Telling Time in Mandarin Chinese

When navigating everyday life, it is important to know how to tell the time in order to schedule meetings, meet up with friends, know that youre running on time, and so on. The Chinese time system is fairly straightforward, and once you have learned your numbers you just need a few more vocabulary words to be able to tell the time. Here is an introduction on how to tell the time in Mandarin Chinese so that you can make plans while in a Chinese-speaking region. Numbering System Before learning talk about time in Mandarin Chinese, you need a solid grasp of Mandarin numbers. Here is a quick review of the Mandarin numbering system: All number vocabulary is based on the numbers from zero to ten.Multiples of 10 are expressed as 2-10 (20), 3-10 (30), etc.Numbers above 10 are expressed as 10-1 (11), 20-3 (23), etc.The number 2 has two forms: à ¨r when counting, and liÇŽng when used with a measure word (as in telling the time). Time Vocabulary This is a list of time-related Chinese vocabulary words. Audio files are included to help you with pronunciation and listening comprehension skills.   Ã¥ ° Ã¦â„¢â€š xiÇŽo shà ­: houré ËœÃ©   ­ (traditional) / é’Ÿå ¤ ´ (simplified) zhÃ… ng tà ³u: hour分é Ëœ / 分钟  fÄ“n zhÃ… ng: minuteç §â€™ miÇŽo: secondæâ€" ©Ã¤ ¸Å  zÇŽo shang:  morningä ¸Å Ã¥ Ë† shà  ng wÇ”:  morningä ¸ ­Ã¥ Ë† zhÃ… ng wÇ”: noonä ¸â€¹Ã¥ Ë† xià   wÇ”: afternoon晚ä ¸Å  wÇŽn shang:  eveningÃ¥ ¤Å"è £ ¡ / Ã¥ ¤Å"é‡Å'  yà ¨ lÇ : late  night甚é º ¼Ã¦â„¢â€šÃ¥â‚¬â„¢ / ä »â‚¬Ã¤ ¹Ë†Ã¦â€" ¶Ã¥â‚¬â„¢? shà ©nme shà ­hou:  when?Ã¥ ¹ ¾Ã© »Å¾ / å‡  Ã§â€š ¹? jÄ « diÇŽn:  what time?

The Steroids Epidemic Essay - 999 Words

What is the first thing that comes to mind when steroids are discussed? Is it positive? Negative? What comes to mind for me is the vision of an extremely large man with bulging muscles like we see in bodybuilding competitions. These types of images are becoming extremely commonplace in society today, and also increasingly disturbing considering just a few short years ago the ‘bodybuilder’s body’ was just a niche in the sports world. But what drove this movement? There is no way to possibly limit this phenomenon into one single cause, but rather I can hazard a guess as to what I believe may be at the root of this ideal change. America, since the time it was founded, has grown increasingly confident in itself.

Steroids are considered very dangerous, fickle substances that have the potential to mess up the user’s bodily functions if care is not taken while on them. Steroids come with three different types of risks/side effects that include: mental health, addictive potential and physical dangers. Steroids have immediate effects on the brain of a user as soon as they begin taking them. As soon as steroids are introduced into the user’s system, they â€Å"[bind to the] androgen (male sex hormone) and estrogen (female sex hormone) receptors on the surface of a cell.† Studies have suggested that â€Å"steroids may contribute to psychiatric dysfunction, paranoid jealousy, extreme irritability, delusions, and impaired judgment stemming from feelings of invincibility† (â€Å"NIDA Inf oFacts: Steroids (Anabolic-Androgenic)†, 2009).

What You Eat Is Your Business Essay Example For Students

What You Eat Is Your Business Essay Food as a global issue Topics on health care are becoming more and more popular, as people need to take care of themselves as good as possible. You are what you eat, and your health condition depends on your nutrition. People should be more responsible for the actions they do with their body. Observations show the dependence of the occurrence of ulcers, tumors, other diseases of the gastrointestinal tract and other systems of the body on the quality of food and insufficiency of vitamin complexes in it. At the same time, there are examples and reverse dependence, while paying attention to the quality of food, the level of the disease population will significantly reduce. It’s simply impossible to maintain the perfect balance of nutrients every day. Dont blame the eater, as the fastest way for making the right choices is to spend a little time each day in order to listen to responsible people, to assess the condition of your skin and your physical and emotional status. What you eat is your business The problem of obesity among adults and children is becoming acute in many countries. Food manufacturers are an obstacle in the struggle for a healthy lifestyle against obesity. People with obesity usually have children with the same problem. Obesity can also have genetic causes, but most children simply take on the bad eating habits of their parents at home or from friends. The problem of obesity of people, as well as health care, personal attitude toward food and the government actions toward it, were the main points of an argumentative essay. The author is American journalist, author of criminal justice, anti-drug and civil liberties in the Washington Post. In what you eat is your business he highlights that government has to depict the situation from the various corners. He suggests the government take charge of regulating the prices of products that provoke obesity and, instead, make available so-called healthy products. Balko argues that the government spending more money on anti-obesity measures is the wrong way to fix the obesity epidemic. He claims that people should be more responsible for their personal health and choices.  It goes without saying that we are the main coordinators of our health and the way of life we lead. So, there is no organization that can make corrections into our lifestyle. Of course, we come across various food temptations, but we have to remember that our face is the mirror of the stomach. So, make the right conclusions. On the other hand, there are opponents of such innovations. They believe that the government will not dictate to people who they are and new gifts will not make problems. The food we consume is absorbed by the walls of the stomach and intestines, after this, it enters the blood, with which it begins to circulate throughout the body. The skin renewal cycle is 28 days; other organs and tissues have their own specific renewal cycle. This is a very difficult cycle. Do you know such rule that the products you ate some days later will appear on your skin the next day. Balko is sure that your personal body consists of what you eat and only you, but not the government, is responsible for the condition of your health. The government can’t save the nation from obesity; the person himself or herself should be responsible for her or his actions. If people want to drink cola with pizza without paying attention to the consequences, so do that. Why should the government take care of it? .u62f4d18ea0d629f00c8060c77b092dfe , .u62f4d18ea0d629f00c8060c77b092dfe .postImageUrl , .u62f4d18ea0d629f00c8060c77b092dfe .centered-text-area { min-height: 80px; position: relative; } .u62f4d18ea0d629f00c8060c77b092dfe , .u62f4d18ea0d629f00c8060c77b092dfe:hover , .u62f4d18ea0d629f00c8060c77b092dfe:visited , .u62f4d18ea0d629f00c8060c77b092dfe:active { border:0!important; } .u62f4d18ea0d629f00c8060c77b092dfe .clearfix:after { content: ""; display: table; clear: both; } .u62f4d18ea0d629f00c8060c77b092dfe { display: block; transition: background-color 250ms; webkit-transition: background-color 250ms; width: 100%; opacity: 1; transition: opacity 250ms; webkit-transition: opacity 250ms; background-color: #95A5A6; } .u62f4d18ea0d629f00c8060c77b092dfe:active , .u62f4d18ea0d629f00c8060c77b092dfe:hover { opacity: 1; transition: opacity 250ms; webkit-transition: opacity 250ms; background-color: #2C3E50; } .u62f4d18ea0d629f00c8060c77b092dfe .centered-text-area { width: 100%; position: relative ; } .u62f4d18ea0d629f00c8060c77b092dfe .ctaText { border-bottom: 0 solid #fff; color: #2980B9; font-size: 16px; font-weight: bold; margin: 0; padding: 0; text-decoration: underline; } .u62f4d18ea0d629f00c8060c77b092dfe .postTitle { color: #FFFFFF; font-size: 16px; font-weight: 600; margin: 0; padding: 0; width: 100%; } .u62f4d18ea0d629f00c8060c77b092dfe .ctaButton { background-color: #7F8C8D!important; color: #2980B9; border: none; border-radius: 3px; box-shadow: none; font-size: 14px; font-weight: bold; line-height: 26px; moz-border-radius: 3px; text-align: center; text-decoration: none; text-shadow: none; width: 80px; min-height: 80px; background: url(https://artscolumbia.org/wp-content/plugins/intelly-related-posts/assets/images/simple-arrow.png)no-repeat; position: absolute; right: 0; top: 0; } .u62f4d18ea0d629f00c8060c77b092dfe:hover .ctaButton { background-color: #34495E!important; } .u62f4d18ea0d629f00c8060c77b092dfe .centered-text { display: table; height: 80px; padding-left : 18px; top: 0; } .u62f4d18ea0d629f00c8060c77b092dfe .u62f4d18ea0d629f00c8060c77b092dfe-content { display: table-cell; margin: 0; padding: 0; padding-right: 108px; position: relative; vertical-align: middle; width: 100%; } .u62f4d18ea0d629f00c8060c77b092dfe:after { content: ""; display: block; clear: both; } READ: My Medical Statement Of Purpose EssayEnjoy different foods Paying attention to what was said before, we are almost sure that many people would agree with the essay â€Å"What you eat is your business† by Balko. Keeping this in mind, we would like to warn you against extremes. Nutrition is an important thing, but, for example, if you find out that apples are good for health, does this mean that it is worth eating only apples? Each nutrient has its effect on the body. So even if you limit your diet to only those products that are certainly beneficial to the body and skin, it will be difficult to achieve a direct effect. After all, to exert a beneficial effect on the body and skin, your food must contain a very wide range of vitamins and minerals. Therefore, remembering that every swallowed piece becomes a part of you, do not refuse the food that gives you pleasure of course, within reasonable limits. People should be more responsible for what they eat and take care of themselves. People should remember that at a time when the ecological state of the environment desires to be better when the food is not of the best quality, it is desirable to maintain a healthy lifestyle and engage in physical education and sports.

The ecstasy of influence a plagiarism Essay Example

The ecstasy of influence: a plagiarism Paper In his essay â€Å"The ecstasy of influence: a plagiarism†, Jonathan Lethem contends that all works of creativity could be found to have elements that have been plagiarized from others, whether the artist consciously or subconsciously committed the copying. The copied part may be a line, theme, or an idea. They are also called many things. In music writing, for instance, reworking of melodic fragments and musical frameworks are called â€Å"versions†. Lethem uses the term â€Å"appropriation† to describe how Bob Dylan used lines and titles from film and literature for his song lyrics. The point is that the practice cuts across â€Å"all forms and genres in the realm of cultural production (Lethem)†. Then again, many masterpieces in various cultural genres—like Shakespeare’s plays or Dylan’s songs—were created because the artist has been inspired by the work of the master. Invention is the creation of something new out of something old or putting together several ideas into one new whole. By the way, if you forget to check an essay for plagiarism, do it right now! The concepts of intellectual property rights and the modern copyright law do not refer to a â€Å"right† in the absolute sense, but a monopoly of those who will benefit from the royalties one has to pay for borrowing elements from another’s creative output. They could instead stump creativity instead of promote it because they make the artist conscious against infringing upon the copyright of others. A creative work should be a springboard for inspiration into the production of a new work. Art should be given and received as a gift. Only then could a piece convey an â€Å"uncommodifiable surplus of inspiration (Lethem)† among its recipients.

Writers, painters or musicians who are being copied should be honored instead of suing the copyists. Artists earn already from their work and they should learn to give some away, like when a poet allows a musician to use a line from his poem. Substantially, all ideas are second hand, unconsciously and consciously copied from somewhere. There is no such thing as an original work, only ones inspired from others. Reference Lethem, Jonathan.

Free Essays on Zero-Tolerance

Policing In the USA The appointment of the Presidents Commission on Law Enforcement and the Administration of Justice (1988) marked the beginning of what is generally considered to have been a period of great change in American policing. However the concept of â€Å"Zero-tolerance† emerged in the 1980s. Zero tolerance was originally intended to send a message to people that certain behaviors would not be tolerated, by punishing both major and minor offenses severely. The Zero tolerance drug programs led to a host of civil rights controversies (Skiba and Peterson, 1999). The term then caught on among educators concerned about youth violence, and school boards across the country adapted to a zero tolerance policies for a range of disrupted behaviors. In 1994, President Clinton signed the Gun Free Schools Act, mandating one year expulsion for possession of fire arms in school. Zero Tolerance, the original version was the ‘broken windows’ thesis which promoted the idea of greater use of ‘beat’ police who patrolled neighborhoods on foot and negotiated acceptable public behavior - constantly making distinctions between the respectable and the disreputable. Importantly, in the original thesis public order was improved and maintained through the informal rules which were worked out at the neighborhood level (Wilson and Kelling 1982, p.30). More recently Kelling and Coles (1997) still stress the need for negotiation of a ‘disorder threshold’ and argue that ‘crackdowns’ and street ‘sweeping’ is far different from the ideas proposed in the broken windows thesis. What are the provisions of the Gun-Free Schools Act? The Gun-Free Schools Act of 1994 mandates a 12-month expulsion for possession of a firearm and referral of law-violating students to the criminal or juvenile justice system. It also requires that state law must authorize the chief administrative officer of each local school district to modify such expulsions on...

Essentially, the aim of the aim of a research paper is to try to raise a problem and try to suggest solutions that can be implemented in order to address that problem. The paper should also have highlighted the gap that should be covered in future research in the event that this research failed to provide solutions that can help prevent the problem.

Biological molecules Essay Example | Topics and Well Written Essays - 1250 words

Biological molecules - Essay Example The two strands of the helix run in opposite directions (1 "up" and 1 "down"). The inner edges of the helices are formed by the nitrogenous bases and they run in pairs. Adenine pairs with thymine with 2 hydrogen bonds and cytosine pairs with guanine with 3 hydrogen bonds (Murray et al, 2007). DNA is present in the chromosomes of most of the living beings. The human genome approximately has 3 billion base pairs of DNA which are arranged in the 23 pairs of chromosomes. Sequence pieces of DNA form genes which carry vital information. The genetic information is achieved by complementary base pairing. Transmission, transcription and translation are the steps involved in transmission of genetic information. Currently, DNA is used in the field of genetic engineering for the treatment of many diseases (Murray et al, 2007). RNA or ribonucleic acid is similar to DNA except that it is single stranded and the sugar present in it is ribose sugar. RNA consists of repeating units of nucleotides which are made up of a nitrogenous base, a ribose sugar and a phosphate. The pyramidines are guanine and cytosine and the purines are adenine and uracil. RNA is transcribed from DNA by the enzyme called RNA polymerase. There are basically 2 types of RNA: coding RNAs and non-coding RNAs. Messenger RNA (mRNA) is a coding RNA. There are many non-coding RNAs. These include ribosomal RNA (rRNA), transfer RNA (tRNA) and others. Functions: mRNA carries information from DNA to the ribosome which is the site of synthesis for proteins. The amino acid sequence in the protein is based on the coding sequence of the mRNA. tRNA and rRNA are involved in the process of translation. Many other non-coding RNAs are involved in RNA processing, gene regulation, catalysis of chemical reactions, cutting and ligation of other RNA molecules, catalysis of peptide bond formation in the ribosomes and other roles (Murray et al, 2007). Carbohydrates Structure: Carbohydrates are organic compounds that are either ketones or aldehydes with many hydroxyl groups added. These hydroxyl groups are added one on each carbon atom that is not a part of either the aldehyde or the ketone group. Thus the general formula of a carbohydrate can be designated as (C'H2O)n. Here n is any number greater than 3. There are many carbohydrates like uronic acids and fucose which don't have this formula in their structure. Also, all chemicals which have this structure do not fall into the category of carbohydrates. The basic carbohydrate units are monosaccharides. These are further classified based on the number of carbon atoms, the placement of the carbonyl group and the chiral handedness. Monosaccharides with the carbonyl group aldehyde are known as aldoses, those with carbonyl group ketone are known as ketoses, those with three carbon atoms are known as trioses, those with four are called tetroses, five are called pentoses and six are hexoses. Each carbon atom wi th a hydroxyl group (except the first and last carbon atoms) is assymmetric making them stereocenters with either right-side configuration or left-side configuration. Thus many isomers can exist for any given monosaccharide formula. Glucose, galactose and fructose are monosaccharides. Monosaccharides can link together in many ways to form disaccharides and poly- saccharides. One or
