During the teenage years, hormonal (荷爾蒙的) 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.
For Boys | For Girls | |||
Age | Height | Weight | Height | Weight |
in Years | in Inches | in Pounds | in Inches | in Pounds |
12-13 | 58-62 | 85-100 | 60-63 | 95-105 |
14-15 | 63-66 | 105-125 | 63-64 | 105-115 |
16-17 | 67-70 | 130-150 | 64 | 115-120 |
18-20 | 68-70 | 150-160 | 64 | 125-130 |
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 fat. So, it can be observed that other than the above mentioned factors, genetic factors also influence the body-fat rct that some female athletes have body fat as low as 10 % and some male athletes had lower than 4% body faatio.
Body Mass Index (BMI)
You may use the following formula to calculate your BMI:
As per SI Units (國際單位) : 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:
BMI Calculated | Conclusion |
BMI 18.5~25 | Normal or ideal weight |
BMI > 25 | Overweight |
BMI < 18. 5 | Underweight |
BMI < 17. 5 | Extremely underweight |
BMI = 30 or BMI > 30 | Obese(病態(tài)肥胖的) |
BMI = 40 or BMI > 40 | Extremely obese |

At the outbreak of war in September 1939, Doreen Luke was fifteen years old and had just begun work as an apprentice (學(xué)徒) in a department store selling clothing and household goods in her hometown of Bodmin in Cornwall. Doreen recalls the first day of war, “My mother was in the process of cooking the Sunday dinner when the Prime Minister announced over the radio that we were at war with Germany… From then on everything changed in our lives. Suddenly there was a different atmosphere.”
During the first years of the war, Doreen was part of a concert party that entertained civilians and service personnel in Cornwall. Although Doreen made effort for the war through her work in entertainment, she was eager to become involved with the war effort in a more direct way, “ My seventeenth birthday came in January 1941. Many of my friends were joining the Forces. I was becoming very restless. In any case soon at the age of eighteen I would be called up to go and work in a factory or to do some other vital war work but that didn’t appeal to me. I was more adventurous than that!”
Realizing that the Women’s Auxiliary Air Force(WAAF)was recruiting (招募) wireless operators, Doreen quickly made up her mind. At the age of eighteen, she received her call-up papers and became a member of the WAAF. After one year’s training, Doreen became a wireless operator at Bletchley Park and began work in the Auto Room. Doreen recalls her first visit to Bletchley and the secrecy essential to her work, “I didn’t realize when I first stepped into that room that I was going to be a part of a very secret department. In fact I didn’t know that until fifty years after the war.”

China is a country on the move- especially around its Lunar New Year holiday. This year, the holiday crush(客流量) promises to be even heavier than before。
Government officials estimate that Chinese people will take to the air, roads and railways 3.62 billion times over a 40-day period around the nation's most important holiday this year as people push their way home for family gatherings or to satisfy their new-found passion for travel.
Getting tickets to all those would-be travelers is a discounting challenge that annually tries patience. And it is the railway system that routinely is most unable to cope. Railways are the transport of choice for low-cost long-distance travel, and that's where the ticketing system routinely falls down
Much of the criticism has, focused on the railway's-online purchasing system. Which has been unable to keep pace with the huge demand and also failed to stop scalpers(票販子) from ending up with many of the hard-to-find tickets.
While insisting that online sales were the fairest way to get tickets for travelers, railway officials told
reporters that the public need to be patient. Efforts were being made to provide online identity checks that would reduce the ticket scalping problems. While officials had little good news for rail passengers, they did manage to bring a few smiles to those traveling by car as the country's extremely expensive highway tolls (通行費(fèi))will be free of charge for the period of the official holiday.
1.Which of the following words can replace the underlined word "discounting" in Paragraph 3?
A. Promising.
B. Discouraging.
C. Pleasing.
D. Rewarding.
2.According to the text, getting tickets_____. around the official holiday.
A. is just a piece of cake
B. is more costly
C. takes great effort
D. is convenient for travelers
3.We can learn from the text that _______. around the New Year holiday.
A. there will be 3. 62 billion people going home
B the railway system will be facing more stress
C.. people's complaint .focus on the failure of online purchase
D. not railways but cars are the best choices for traveling
4.Which of the following can best describe the author's attitude to the railway service?

D.Worried.

One of the common complaints we hear from the people around us are problems they are facing. Every day and everywhere there are problems. Many times we find it hard to stay happy. When one problem is solved, another one comes up. How to solve them? The answer is that we must equip ourselves to deal with different kinds of worries by learning the three basic steps of problem analysis. The three steps are:
Get the facts
Why is it so important to get the facts? Unless you have the facts, you can’t possibly attempt to solve your problem intelligently. Without the facts, all you can do is wondering around in confusion. It is not an easy job to get facts. When you are worried, your emotions are riding high. 1. .
When trying to get the facts, you can pretend that you are collecting this information not for yourself but for some other person. 2. You can also pretend that you are a lawyer preparing to agree. Try to get all the facts both on your side and the other side of the case. You will generally find the truth lies somewhere in between.
3.
Whenever you are worried, write down the questions that make you worry. And write out all the various steps you could take and then the probable consequences of each step. For example, what am I worrying about? What can I do about it? Here is what I’m going to do about it. After carefully weighing all the facts, you can calmly come to a decision.
Act on that decision.
4. How can you break the worry habit before it breaks you? Crowd worry out of your mind by keeping busy. Plenty of action is one of the best ways to cure worry. 5. If you know a situation is beyond your power, say to yourself: “It is so; it can’t be otherwise.” Don’t permit little things to ruin your happiness. Try to cultivate a mental attitude that will bring you peace and happiness.
A. Analyze the facts.
B. Accept what can’t be avoided.
C. Decide how much anxiety a thing may be worth.
D. This will help you to take a cold and fair view of the evidence.
E. There comes a time when you must decide and never look back.
F. But here are two ideas that can help you see the facts in a clear and objective way.
G. Unless you take your action, all your face-finding and analysis is a sheer waste of energy.

Conventional wisdom says that hardship can make us old before our time. In fact, a new study suggests that violence not only leaves long-term scars on children?s bodies, but also changes their DNA, causing changes that are equal to seven to ten years of premature aging.
Scientists measured this by studying the ends of children?s chromosomes(染色體), called telomeres, says Idan Shalev, lead author of a study published in Molecular Psychiatry.
Telomeres are special DNA sequences which prevent the DNA in chromosomes from separating. They get shorter each time a cell divides, until a cell cannot divide any more and dies.
Several factors have been found to shorten telomeres, including smoking, radiation and psychological stresses such as being treated badly when young and taking care of a chronically ill person.
In this study, researchers examined whether exposure to violence could make children’s telomeres shorten faster than normal. They interviewed the mothers of 236 children at ages 5, 7 and 10, asking whether the youngsters had been exposed to domestic violence between the mother and her partner; physical maltreatment by an adult; or bullying. Researchers measured the children’s telomeres—in cells obtained by swabbing the insides of their cheeks—at ages 5 and 10.
Telomeres shortened faster in kids exposed to two or more types of violence, says Shalev. Unless that pattern changes, the study suggests, these kids could be expected to develop diseases of aging, such as heart attacks or memory loss, seven to 10 years earlier than their peers.
Shalev says there is hope for these kids. His study found that, in rare cases, telomeres can lengthen. Better nutrition, exercise and stress reduction are three things that may be able to lengthen telomeres, he says.
The study confirms a small but growing number of studies suggesting that early childhood adversity imprints itself in our chromosomes, says Charles Nelson, a professor of pediatrics and neuroscience at Harvard Medical School.

A. hardship can change a child?s aging
B. violence leaves scars on a child?s mind
C. violence can speed up a child?s aging

2.According to the text, telomeres ________.
A. are at the ends of people?s chromosomes
B. can help prevent DNA from separating

3.Which of the following is TRUE according to the text?
A. Violence can cause quick cell division in children?s body.
B. Researchers measured the children?s telomeres from their legs in the study.
C. Being treated badly will make a child?s telomeres shorten faster.
D. Children who have shorter telomeres may have a heart attack earlier.
4.What is the best title for the text?
A. Violence Aging Children?s DNA
B. Children?s Changing DNA Patterns
C. Violence and Telomeres
D. The Function of Telomeres

When I was younger, I thought that boys and grown men should not cry. The tears were signs of being weak and a sissy(膽小鬼), which a man is not supposed to be. This was even strengthened in my young mind when the song, Boys Don't Cry, came out in the early 1980s.
But just this June, I discovered that courage is not all about trying to keep all the pain inside in check. Courage is not all about trying to hide the tears. It is the opposite — the tears strengthen the heart's courage. And I saw this in my father. That day my father cried.
My 18-year-old sister eloped (私奔) and from it I saw how weak my father's heart was. My sister and I were used to seeing him as an iron-willed figure and authoritarian father.
For three days after my sister eloped, he would not talk. He would just sit quietly outside our house in the dark. On the fourth night, I sat beside him and asked him to tell me what he felt about everything.
It has been years since I have laid my hand on my father's shoulder as we have drifted apart (疏遠(yuǎn)) farther and farther while I was growing up. That night,though, I sensed my father trying to control his pain and I wanted him to be able to let it out. We have all cried over what happened except him. All of us except him.
The simple touch and my words, “Dad, it is not your fault.”, broke my father's dam. In the darkness, he began to cry. I felt his shoulders shaking as he whispered, "Where did I go wrong? All I ever wanted was for my children to grow up right. Why couldn't your sister wait?"
I understood then why he preferred to be in the dark. By being there, he hoped to spare his family of a father's pain. His tears, though we did not see them before that night, were there all the same. I saw his courage, that night when my father cried with my hand on his shoulder, and understood his pain.
