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.

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

The Occupy protests(抗议) in Hong Kong are approaching an end. Traffic on Mong Kok’s Argyle Street resumed in the late afternoon after the clearance of the barriers and tents by protesters, who remained largely calm, only resisting the clearance at several points.
Some 3,000 police officers were deployed(部署) in the operation, a much higher number than were used to assist in the clearance of a protest site in Admiralty District on November 18.
The operation in Mong Kok comes a week after the partial clearance of another protest site next to the local government headquarters in Admiralty, bringing an end to the months-long protest movement.
Some 3,000 police officers also stood guard at the former protest site in Admiralty on Tuesday.
Hong Kong Chief Executive Leung Chun-ying expressed on Tuesday his hope that business could resume for shops in the area. He also restated that the protest was an unlawful gathering, and called for the protesters to respect and obey the law.
“The common call of Hong Kong people has finally been answered. Now the protest is coming to an end which is necessary and unavoidable. The public has suffered enough,” Leticia Lee See-yin told the Global Times.
“Many people are living in Mong Kok or operating their businesses in the area. They are all angry at the protest for affecting their business. Two shop owners even shut down their stores because they can no longer afford losses caused by the protest,” said Lee.
It is believed that the successful clearance of the Mong Kok site has proven that the protests are decreasing as they approach an end.
“The authorities met with much less resistance compared to a month ago when protesters reacted violently when police tried to remove barriers in the same area in Mong Kok. Now the public has expressed a stronger desire than ever for the protest to end,” Tang Ka-piu, a lawmaker, told the Global Times.The underlined word “resumed” in the first paragraph most probably means “_______”.

My 16-year-old son, Anton, had gone to the local swimming hole. Most of the kids who swim there are fit and strong teens, and there are plenty of rocks for them to use as safe harbors, so I had no fears for his well-being. Still, the firefighter’s first words, “You need to come up here to the Stillwater River,” made me catch my breath.
When I got to the river, I saw Anton sitting quietly on a low platform of the fire engine, with a towel wrapped about his shoulders.
I hurried over to him. “You OK?” I asked.
“Yeah,” was all he said. But my eyes begged for an explanation. I didn’t get it from my son.
The story was this: A couple in their 20s, unfamiliar with the Stillwater, had gotten caught in the current and began screaming for help. Without hesitation Anton and his friend dived into the water, swam out to the drowning(溺水的) woman, and brought her safely to shore.
In an age in which the world “hero” is broadcast with abandon(随意）and seemingly applied to anyone, I realized the real thing in my son and his friend—the disregarding of personal safety for the sake of another human being. I know that teens are headstrong and self-centered, but this didn’t lower the gravity of the event and the desire to do good.
Along the way home I tried to get some more information from him, but the only words were, “What’s for supper?”
I thought twice about the tragedy(悲剧) that might have been. Questions flew across my mind like a flight of swallows: Would I have risked my life to save a drowning person? Or would I have chosen to dial 911? Would I have told the story over and over to anyone who’d listen?
The next morning, when Anton got up, I half expected him to tell me the story from his point of view, now that he had some distance from the event. But all he did was to toast a pie, pull himself together, and head for the door to begin the new day.The writer caught her breath when she heard the fire fighters’ first words because______.
| A．her son saved a woman |
| B．she was scolded by fire fighters |
| C．she was anxious about her son’s safety |
| D．her son was to blame for a fire |
We can infer from the passage that _______.
| A．firefighters always turn up in case of emergency |
| B．parents are always worried about their children |
| C．it’s dangerous to swim in an unfamiliar river |
| D．teens are more responsible than expected |
Which would be the best title for the passage?
| A．My Mother, My Love | B．My Son, My Hero |
| C．A Narrow Escape | D．A Silent Boy |
Anton kept silent about his deed because_______.
| A．he was still in fear |
| B．he was annoyed with mother |
| C．he regarded it as a normal thing |
| D．he was afraid of being scolded |
As a young boy, I sometimes traveled the country roads with my dad. He was a rural mail carrier, and on Saturdays he would ask me to go with him. Driving through the countryside was always an adventure: There were animals to see, people to visit, and chocolate cookies if you knew where to stop, and Dad did.
In the spring, Dad delivered boxes full of baby chickens, and when I was a boy it was such fun to stick your fingers through one of the holes of the boxes and let the baby birds peck on your fingers.
On Dad's final day of work, it took him well into the evening to complete his rounds because at least one member from each family was waiting at their mailbox to thank him for his friendship and his years of service. "Two hundred and nineteen mailboxes on my route," he used to say, “and a story at every one." One lady had no mailbox, so Dad took the mail in to her every day because she was nearly blind. Once inside, he read her mail and helped her pay her bills.
Mailboxes were sometimes used for things other than mail. One note left in a mailbox read, "Nat, take these eggs to Marian; she's baking a cake and doesn't have any eggs." Mailboxes might be buried in the snow, or broken, or lying on the ground, but the mail was always delivered. On cold days Dad might find one of his customers(顾客) waiting for him with a cup of hot chocolate. A young girl wrote letters but had no stamps, so she left a few buttons（纽扣）on the envelope in the mailbox; Dad paid for the stamps. One businessman used to leave large amounts of cash（现金）in his mailbox for Dad to take to the bank. Once, the amount came to $ 32,000.
Ten years ago, when I traveled back to my hometown on the sad occasion of Dad's death, the mailboxes along the way reminded（回想） me of some of his stories. I thought I knew them all, but that wasn't the ease.
As I drove home, I noticed two lamp poles(杆), one on each side of the street. When my dad was around, those poles supported wooden boxes about four feet off the ground. One box was painted green, and the other was red, and each had a long narrow hole at the top with white lettering: SANTA CLAUS, NORTH POLE. For years children had dropped letters to Santa through those holes.
I made a turn at the comer and drove past the post office and across the railroad tracks to our house. Mom and I were sitting at the kitchen table when I heard footsteps. There, at the door, stood Frank Townsend, Dad's postmaster and great friend for many years. So we all sat down at the table and began to tell stories.
At one point Frank looked at me with tears in his eyes. "What are we going to do about the letters this Christmas?" he asked.
"The letters?"
"I guess you never knew."
"Knew what?"
"Remember, when you were a kid and you used to put your letters to Santa in those green and red boxes on Main Street? It was your dad who answered all those letters every year. "
I just sat there with tears in my eyes. It wasn't hard for me to imagine Dad sitting at the old oak table in our basement reading those letters and answering each one. I have since spoken with several of the people who received Christmas letters during their childhood, and they told me how amazed they were that Santa had known so much about their homes and families.
For me, just knowing that story about my father was the gift of a lifetime.It can be inferred from the passage that the writer considered his travels with Dad as .
| A．great chances to help other people |
| B．happy occasions to play with baby chickens |
| C．exciting experiences with a lot of fun |

| A．Dad had a strong sense of duty |
| B．Dad was an honest and reliable man |
| C．Dad had a strong sense of honor |
| D．Dad was a kind and generous man |

| A．Dad read letters for a blind lady for years. |
| B．Dad paid for the stamps for a young girl. |
| C．Dad delivered some eggs to Marian. |
| D．Dad answered children's Christmas letters every year. |
What surprised the children most when they received letters in reply( 回复) from Santa Claus every year?
| A．Santa Claus lived alone in the cold North Pole. |
| B．Santa Claus answered all their letters every year. |
| C．Santa Claus had unique mailboxes for the children. |
