Answer each question according to the required words limit.

  If you have ever been rock climbing, you will know that it is not a very easy sport.

  There are three basic types.Top roping is probably the most common type and is basically climbing with a partner.Lead climbing is very similar to top roping.In both types, the climber can sit off the wall and rest on the rope.

  Bouldering is a type of free climbing without any type of ropes or harnesses(保护带).This is the most challenging of all types of climbing.The climber must be able to complete the task without taking a rest on the rope.

  Believe it or not, climbing is said to be about 75% legs and 25% arms.To climb successfully, the climber must master a wonderful technique.One of the major rules is to always have 3 points touching the wall, whether it is both feet and one hand, or one foot and both hands, it is much easier to have your weight rest on 3 points than on 2.Another important technique to grip(抓紧)is that your arms will not do the climbing in most cases.They only hold you into the wall so that your legs can push you upward.The closer you are to the wall, the easier it is to climb.

  Rock climbing may sound too extreme but it is really an amazing exercise and mentally challenging, too.

Though I have traveled in hundreds of trains, few unusual things have ever happened to me. But one day in a train something did happen. I do not mean that I was hurt: no one was hurt.

I do my work in a hot country far away from England. Every September I go there to do my business, and every July I come back to England to have a rest. So every September I go to Paris and take a train from the great French city to Mendova, and at Mendova I catch my ship.

There is one very fast train from Paris to Mendova, and it suits me well. It goes as far as Endoran, but it stops at Mendova for a few minutes to let travelers get out or in. It is called The Flying Bluebird. It reaches Mendova at seven minutes past nine in the morning, and it is never late.

A ship leaves Mendova at half past eleven, and so you will understand that The Flying Bluebird suits me very well. I always travel by it, and I have nearly two and a half hours at Mendova to go from the station to the ship. That is more than enough time.

Well, one September night, I took my place in The Flying Bluebird as usual. The train leaves Paris at nine o’clock every night, and I was in my place soon after half past eight. There were three or four people there with me, but very soon a lot of others got into the train. When no more people could sit down, they began to stand up near us and also in the corridor(走廊). In a short time the corridor was full too, and it was impossible for any more travelers to get into the train.

I could see a lot of other people outside the corridor windows, but they could not get in, and the train left Paris without them. The man sitting next to me started to ask all kinds of questions: “Where do you work? How long does it take you to get there? Are you married? How many children do you have? How much money do they pay you every year? How much do you have in the bank? How much do you spend every month?”

He asked questions for about twenty minutes but I did not give him any clear answers, and at last he stopped and began to read the paper.

I usually sleep quite well in the train, but this time I slept only a little. There were too many people, and there were too many things: small bags, large bags, coats, hats, boxes, newspapers and food. As usual, we got angry about the window. Most people wanted it shut, and two of us wanted it open. But that always happens. It was shut all night, as usual.

When I awoke in the early morning I felt hot and dirty, and glad that the journey was reaching its end. At seven minutes past nine The Flying Bluebird stopped. We were at Mendova, and I stood up thankfully. I took my two suitcases, held one in each hand, and tried to move towards the door into the corridor. In order to get out of the train, I had to pass down the corridor to the door at the far end. There was no other way out.

I could not even into the corridor. There was a suitcase on the floor by my feet, and three men were standing in my way. I felt a touch of fear. I had to get out, you see; I had to catch my ship, which left at half past eleven. And the train did not stop again until it reached Endoran, two hundred miles away.

“I must get out!” I cried. Everyone there understood me, but no one could move.

At last I was able to put one foot over the suitcase on the floor, and I nearly reached the door into the corridor. But then, very slowly, the train began to move. It was taking me away!

“Stop!” I cried. “I want to get out!” But no one outside the train could hear me, and the people inside did not care much. The train moved a little faster. What could I do? I was not even in the corridor.

Fear made me think quickly. In front of my eyes, just, above the door, was a notice that told everyone how to stop the train. I had to pull an iron thing near the notice. I did not waste time. I pulled it.

Well, a noise started above our heads. That was to show everyone that there was something wrong. It was not a small sound. Possibly the men in my ship two miles away could hear it. Then the train stopped.

No one likes to stop a train if there is no need. But I had to catch my ship. That was the only thought in my mind: to get out and catch my ship.

Height is just one of the thousands of features your genes(基因)decide. In fact, because you have two parents, your genes provide you a height that usually lands somewhere between the height of each parent. If both your parents are tall, then most probably you will be tall, too, but if you have questions about how tall you're going to be, ask your doctor if he or she can help you find it out.

But genes don't decide everything. For example, eating an unhealthy diet can keep you from growing to your full potential(潜力). Getting plenty of sleep and enough exercise will help you grow to the expected height.

No doubt(怀疑) you're wondering how fast you should grow. It depends. There's no perfect or right answer. Generally speaking, kids grow about 2 inches (6 centimeters) a year between age 3 and the time when they start puberty (when your body starts changing and becoming more grown up).

Your doctor will know how your growth has been going over the years. Two centimeters here and 2 inches there are not nearly as important as the height you're at now, how you've been growing up to this point, and what other changes your body may be going through.

Don't be scared if you seem to have grown a lot in a very short time. Everyone has a growth spurt(高峰)during puberty. The age for starting puberty is about 10 for girls and about 11 for boys. But it can be earlier or later ——between 7 and 13 for girls and 9 and 15 for boys.

You'll usually begin to notice that you're growing faster about a year or so after your body starts to show the first changes of puberty.

1.If you want to know how fast and how tall you should grow, ____________.

   A. you should have enough exercise           B. you can ask doctors for help

   C. you should save the environment           D. You can record your growth during puberty

2. This passage is mainly about ____________.

   A. how the genes work in your body           B. when is the time you grow fast

   C. why you look like your parents                D. how you grow to a certain height 

3. After reading this passage, we can explain ___________.

   A. how good it is to be a doctor             B. how much sleep time we need

   C. why genes can’t decide everything            D. what healthy diet is

4. Which is NOT mentioned in the passage?

   A. Your height most probably depends on how high your parents are.

   B. Girls’ age for starting puberty is usually earlier than that for boys’.

   C. The time showing the first changes of puberty is never noticed.

   D. You may be scared sometimes when you grow too fast.
