You may think that sailing is a difficul...

    You may think that sailing is a difficult sport, but it is really not hard to learn it. You do not need to be strong. But you need to be quick. And you need to understand a few basic rules about the wind. First, you must ask yourself, “Where is the wind coming from? Is it coming from ahead or behind or from the side?” You must think about this all the time on the boat. The wind direction tells you what to do with the sail.

Let’s start with the wind blowing from behind. This means the wind and the boat are going in the same direction. Then you must always keep the sail outside the boat. It should be at a 90° angle (角度) the boat. Then it will catch the wind best.

If the wind is blowing from the side, it is blowing across the boat In this case, you must keep the sail half way outside the boat. It should be at a 45° angle to the boat. It needs to be out far enough to catch the wind, but it shouldn’t flap (摆动). It shouldn’t look like a flag on a flagpole. If it is flapping, it is probably out too far, and the boat will slow down.

Sailing into the wind is not possible. If you try, the sail will flap and the boat will stop. You may want to go in that direction. It is possible, but you can’t go in a straight line. You must go first in one direction and then in another. This is called tacking. When you are tacking, you must always keep the sail inside the boat.

1.What should you consider first while sailing?

A.Wave levels. B.Size of sails.

C.Sailors’ strength. D.Wind directions.

2.What does the word “It” underlined in Paragraph 4 refer to?

A.The boat. B.The wind.

C.The sail. D.The angle.

3.What do you have to do when sailing against the wind?

A.Tack the boat. B.Lower the sail.

C.Move in a straight line. D.Allow the sail to flap.

4.Where can you probably find the text?

A.In a physics textbook. B.In a tourist guidebook.

C.In a popular magazine. D.In an official report.

 

1.D 2.C 3.A 4.C 【解析】 本文是一篇说明文。文章介绍了帆船运动的一些常识,进行帆船运动必须掌握风向,风向决定着帆船的运动速度。后文分别就顺风行驶、侧风行驶和逆风行驶进行了阐述。 1.细节理解题。根据第二段中的First, you must ask yourself, “Where is the wind coming from? Is it coming from ahead or behind or from the side?(首先,你必须问自己,“风是从哪里来的?”它是从前面、后面还是侧面来的?)由此可知,航行时你首先应该考虑风向。故选D。 2.词义猜测题。根据第三段If the wind is blowing from the side, it is blowing across the boat In this case, you must keep the sail half way outside the boat. It should be at a 45° angle to the boat.(如果风是从侧面吹过来的,在这种情况下,它是吹过船的,你必须让帆保持在船的一半之外。它应该和船成45度角。)可知划线词it所在的句子意思是为了获得风,船帆需要伸的足够远。it指代上文提到的the sail。故选C。 3.细节理解题。根据文章最后一段中的It is possible, but you can’t go in a straight line. You must go first in one direction and then in another. This is called tacking. (这是可能的,但你不能走直线。你必须先往一个方向走,然后再往另一个方向走。这就是所谓的“改变船的航向”。)由此可知,逆风航行时,你必须改变船的航向。故选A。 4.推理判断题。根据第一段You may think that sailing is a difficult sport, but it is really not hard to learn it.(你可能认为帆船运动很难,但其实学起来并不难。)结合全文内容,可知这篇文章主要讲了帆船运动是普通的一种体育运动,因此,本文很可能从流行杂志中节选。故选C。

I was leaving the book store this afternoon when I saw a poor family— a mother and her four kid sitting in the cold, that brought back memories to my childhood. The little girl, who was about 13, told me he liked my sweater. I said “Thank you” her. When I was walking to my car, I was started to feel sad. After I put the books in my car, I sudden thought the little girl might need a sweater at the school. So I went back to find the little girl, take my sweater off but gave it to her. I knew she would get much use out of it than me.

    Let children learn to judge their own work. A child learning to talk does not learn by being corrected all the time.1.

He notices a thousand times a day the difference between the languages he uses and the language those around him use. Bit by bit, he makes the necessary changes to make his language like other people‘s.

2.They learn to do without being taught--to walk, run, climb, whistle, and even ride a bicycle. They compare their own performances with those of more skilled people, and slowly make the needed changes.

But in school we never give a child a chance to find out his own mistakes and correct them for himself.3. We act as if we thought that he would never notice a mistake unless it was pointed out to him, or correct it unless he was made to. Let him work out, with the help of other children if he wants, what this word says, what answer is to that problem, and whether this is a good way of saying or doing this or not.

If it is a matter of right answers, as it may be in mathematics or science, give him the answer book.4.

Why should we teachers waste time on such daily work 5. Let the children learn what all educated people must some day learn, how to measure their own understanding, how to know what they know or do not know.

A.We do it all for him.

B.Point out his mistakes.

C.Let him correct his own papers.

D.If corrected too much, he will stop talking.

E.We allow him to learn from other children.

F.Children learn to do all the other things in the same way.

G.We can only help the child when he has no way to solve a problem.

    Daban town is famous for girls and windmills, while Loulan is a mystery in the desert. Two thousand years ago, beside the beautiful Luobu Lake, there lay Loulan ancient city of the Silk Road. Businessmen from every country gathered there with lots of dancing parties. Everything shows that people in Loulan lived a rich life at that moment.

However, two thousand years later, this rich land suddenly disappeared from the map of China. It became an area covered with sand and dead tree trunks (树干).

Loulan was first “discovered” by a Swedish man named Sven Hedin in 1900, and people from America, Britain, Japan and Sweden all set foot here. Then in the 1930s, a Chinese named Huang Wenbi came to Loulan for the first time. He visited and studied this area and found many relics that were beautifully and carefully made.

It is recorded that the ancient city of Loulan was the capital of the Loulan Kingdom during the Han and Jin Dynasties, and covered an area of some 10, 000 square kilometres. Inside the city, there are the ruins of government offices, temples and other old buildings. Outside the city there are some dried-up rivers and much farmland. In the past century many things have been dug up there including Han Dynasty coins, mirrors and many others of Greek and Roman times. All these things show that a lot of business between the East and the West once took place there.

Lying on the northwest of the Lop Nur area, the Loulan Kingdom is now a lifeless area with endless “forests” of mounds which aren‘t easily seen in other parts of the world. Its mystery has been attracting many people from many countries all over the world.

1.Who was the first person to set foot in Loulan in the 20th century?

3.What can be inferred from the text?

C.Too many people gathered in Loulan and destroyed it.

D.How Loulan ancient city disappeared is still unknown to us.
