During the teenage years, hormonal (荷尔蒙的) changes lead to physical changes like rapid muscle growth, burst in height, and weight gain in both boys and girls. Take a look at the information and height and weight charts for teens presented in this article if the question “How much should I weigh for my age and height” is bothering you.
Average Height and Weight Charts for Teens
Faster growth in kids usually can be noticed at age 8. Genetic factors also determine the physical growth of a child. So, it is perfectly normal for two kids of the same age to have different weights and heights. The following figures should be used as guidelines only.

Ideal Body Fat Percentage
Fit men have 14% - 17% body fat.
Fit women have 21% -24% body fat.
Male athletes have 6% -13% body fat.
Female athletes have 14% - 20% body fat.
The ideal body fat percentage varies mainly according to age, sex and the physical activity of the individual. But it is a fact that some female athletes have body fat as low as 10 % and some male athletes had lower than 4% body fat. So, it can be observed that other than the above mentioned factors, genetic factors also influence the body-fat ratio.
Body Mass Index (BMI)
You may use the following formula to calculate your BMI:
As per SI Units (国际单位) : BMI =" mass" (kg)/[height (meters) ]2
Imperial (英制的) Units 1: BMI =" mass" (Ib. ) x703/[ height (in. ) ]2
Imperial Units 2: BMI =" mass" (Ib. ) x 4. 88/[ height (ft) ]2
Following conclusions can be derived from (得到) calculating the BMI:

“Image is everything.” An entire industry has been built upon the assumption that image is everything, but when it comes down to it, an appealing image is not enough. If there is no substance(事实)behind the image, the product, service or person will fail eventually.
First of all, one should consider how important image is in the selling of products and services. Advertising agencies have raised the art of creating an image to a state of near perfection. Public concept of that product or service is certainly managed by the images created by the advertising agencies.But if the product or service does not live up to the image that was created, the customer will be very dissatisfied and possibly ask for their money back. For example, the Arthur Andersen accounting firm had spent decades building up an image of trustworthiness. But the recent scandal (丑闻) showed that behind that image, it cheated in business practices. Despite the previous positive image, the firm is being accused of criminal actions and it will probably not survive as a business unit. Although the image had been nearly perfect, the reality behind the image has led to the downfall of the world famous accounting firm.
Similarly, personal advisers can build up a public image for politicians and movie stars. Putting out positive news releases, making sure that only the best photographs are published, and ensuring that the person is seen in all the right places can build up a very positive image in the view of the general commons. But once again, history is filled with examples of both politicians and movie stars that fell from grace like the story of the Hollywood actor giving in to the pressures of fame and fortune. With people, just as with products and services, image is certainly important, but without positive substance behind the image, failure is close.
To summarize, it is clear that an appealing image is extremely important to success, whether that image is related to selling a product or service or to the “selling” of a person. But image is only half of the equation. What lies behind that image is every bit as important as the image itself —— the person or product must deliver on that image or there is little chance for long-term success.The downfall of the Arthour Andersen accounting firm is due to ___________.
A.its dishonesty in business | B.its previous images |
C.its bad management | D.its poor service |
Why did some famous people fall from grace?
A.Their images were not well built up. |
B.They failed to live up to their images. |
C.They felt much pressure from the public. |
D.They paid little attention to fame and fortune. |
The structure of the passage is ___________.
A: Argument P: Point C: ConclusionThe author tries to argue that ___________.
A.image creates everything |
B.image is the key to success. |
C.truth is unlikely ever to be equaled |
D.truth and image are equally important |
Today is National Bike-to-Work Day. And on New York City’s jammed streets, people are cycling on hundreds of miles of new bike lanes. But New York’s widespread efforts to make streets safer for bikes have also left some locals complaining about the loss of parking spots and lanes for cars.
When the weather is good, Aaron Naparstek likes to pedal(用踏板踩)his two young kids to school on a special Dutch-made bicycle. Naparstek supports the new lane.
Aaron: The bike lane on Prospect Park West is really introducing a lot of new people to the idea that it’s possible to use a bike in New York City for transportation or to travel around. This is what 21st century New York City looks like.
Prospect Park West is still a one-way road, but where it used to have three lanes of car traffic, now it has two, plus a protected bike lane. Supporters say that makes the road safer for everyone, including pedestrians, by slowing down cars and taking bikes off the sidewalk. But some longtime residents disagree. Lois Carswell is president of a group called Seniors for Safety. She says the two-way bike lane is dangerous to older residents who are used to one-way traffic.
Lois: We wanted a lane — the right kind of lane that would keep everybody safe, that would keep the bikers safe. But we want it to be done the right way. And it has not been done the right way.
Craig Palmer builds bars and restaurants in Manhattan. I was interviewing him for a different story when he brought up the bike lanes all on his own.
Craig: I think the biggest problem is that Bloomberg put all these bike lanes in. You took what used to be a full street and you’re shrinking it.
Then there are the Hasidic Jews in Williamsburg, Brooklyn, who forced the city to remove a bike lane through their neighborhood. But polls show that the majority of New Yorkers support bike lanes by a margin of 56% to 39%. Bicycle advocate Caroline Samponaro of Transportation Alternatives calls that a mandate.
Caroline: If this was an election, we would have already had our victory. The public has spoken and they keep speaking. And I think, more importantly, the public is starting to vote with their pedals.What does Aaron mean by saying “This is what 21st century New York City looks like.”?
A.There are hundreds of miles of new bike lanes in 21 st century New York City. |
B.Drivers slow down their cars and bikes are taken off the sidewalk in New York. |
C.Bikes are used as a means of transport in 21 st century New York City. |
D.It’s possible to make the streets safe for pedestrians in New York. |
According to the passage, which of the following CANNOT support the opponents of these new bike lanes?
A.Drivers lose parking spots and lanes for cars. |
B.The two-way bike lane is dangerous to older residents. |
C.We took what used to be a full street so the road is broader than before. |
D.The removal of one bike lane through a neighbourhood in Brooklyn was not supported. |
“A mandate” in Paragraph 8 was referred to a demand or command from ___________.
A.the authority | B.the public |
C.the supporters | D.the government |
What of the following might be the best title of the passage?
A.Ride on National Bike-to-Work Day |
B.A New Bike Lane Appears in New York |

Traditional fairytales are being abandoned by parents because they are too scary for their young children, a study found.
Research revealed one in five parents has ditched old classics such as Snow White and the Seven Dwarves and Rapunzel in favour of more modern books. One third of parents said their children have been left in tears after hearing the horrible details of Little Red Riding Hood. And nearly half of mothers and fathers refuse to read Rumplestiltskin to their kids as the themes of the story are kidnapping and execution. Similarly, Goldilocks and the Three Bears was also a tale likely to be left on the book shelf as parents felt it forgives stealing.
The survey of 2,000 adults was conducted to mark the launch of the hit US drama GRIMM, which starts tonight at 9 p.m. on Watch, and sees six episodes(片段) based on traditional fairytales. The poll found a quarter of parents polled wouldn’t consider reading a fairytale to their child until they had reached the age of five, as they prompt too many awkward questions from their offspring(后代子孙).
Steve Hornsey, General Manager ofWatch, said: “Bedtime stories are supposed to soothe children and send them off to sleep soundly. But as we see in GRIMM, fairytales can be dark and dramatic tales so it’s understandable that parents worry about reading them to young children.”
“As adults we can see the innocence in fairytales, but a five year old with an over active imagination could take things too seriously. Despite the dark nature of classic fairytales, as we see in GRIMM, good will triumph over evil and there is always a moral to the story.”
The study also found two thirds of mums and dads try to avoid stories which might give their children nightmares.
However, half of parents said traditional tales are more likely to have a strong moral message than a lot of modern kids’ books, such as The Gruffalo, The Hungary Caterpillar and the Mr. Men books.Why don’t some parents want to read Rumplestiltskin to their kids?
A.Rumplestiltskin is too long. |
B.Rumplestiltskin is too difficult. |
C.Rumplestiltskin forgives stealing. |
D.Rumplestiltskin may influence Children badly. |
We can learn from paragraph 3 that Grimm is ___________.
A.a fairytales book |
B.a movie for children |
C.a play loved by children |
D.a drama based on traditional fairytales |
The underlined word “soothe “in paragraph4 can be replaced by___________.
A.put down | B.calm down | C.take down | D.come down |
What’s the author’s attitude towards traditional fairytales?
A.Optimistic | B.Not mentioned |
C.Casual | D.Disapproving |
Recently there was a major discovery in the scientific research—the mapping of all DNA in a human gene(基因) is complete.Couple of years ago, this seems an impossible task for scientist to accomplish.All this progress in science leads us to believe that the day, when the human being will be cloned, is not far away.Human cloning has always been a topic of argument, in terms of morality or religion.
Taking a look at why cloning might be beneficial, among many cases, it is arguable that parents who are known to be at risk of passing a genetic limitation to a child could make use of cloning.If the clone was free of genetic limitations.then the other clone would be as well.The latter could foe inserted in the woman and allowed to ripen to term.Moreover, cloning would enable women, who can't get pregnant, to have children of their own.
Cloning humans would also mean that organs could be cloned, so it would be a source of perfect transfer organs.This, surely would be greatly beneficial to millions of unfortunate people around the world that are expected to lose their lives due to failure of single (or more) organ (s).It is also arguable that a ban on cloning may be unlawful and would rob people of the right to reproduce and limit the freedom of scientists.
Arguments against cloning are also on a perfectly practical side.Primarily, I believe that cloning would step in the normal "cycle" of life.There would be a large number of same genes, which reduce the chances of improvement, and, in turn, development—the fundamental reason how living things naturally adapt to the ever-changing environment.Life processes failing to do so might result in untimely disappearance.Furthermore, cloning would make the uniqueness that each one of us possesses disappear.Thus, leading to creation of genetically engineered groups of people for specific purposes and, chances are, that those individuals would be regarded as "objects" rather than people in the society.
Scientists haven't 100 per cent.guaranteed that the first cloned humans will be normal.Thus this could result in introduction of additional limitations in the human "gene-pool".
Regarding such arguable topics in "black or white" approach seems very innocent to me personally.We should rather try to look at all "shades" of it.I believe that cloning is only legal if its purpose is for cloning organs; not humans.Then we could regard this as for "saving life" instead of "creating life".I believe cloning humans is morally and socially unacceptable.Which of the following is true according to the passage?
A.Genetic limitation will be beneficial for some women |
B.A large number of genes will prevent us from developing |
C.Prohibition of cloning might limit the freedom of scientists |
D.First cloned humans might be normal according to scientists |
What's the author's opinion on cloning?
A.Cloning should be entirely banned. |
B.Cloning should be used in creating life. |
C.Cloning will take away the right to reproduce. |
D.Cloning is acceptable if it is used for cloning organs. |
Where can you read this article?
A.In a story book |
B.In a magazine |
C.In a science fiction |
D.In a brochure |
