閱讀下面的短文，并完成短文后的任務(wù)。
Have you ever wondered why birds sing? Maybe you thought that they were just happy. After all, you probably also sing or whistle when you are happy.
Some scientists believe that birds do sing some of the time just because they are happy. However, they sing most of the time for a very different reason. Their singing is actually a warning to other birds to stay out of their territory.
Do you know what a “territory” is? A territory is an area that an animal, usually the male, claims（宣稱）as its own. Only he and his family are welcome there. No other families of the same species（物種）are welcome. Your yard and house are your territory where only your family and friends are welcome. (76▲) If a stranger should enter your territory and want to hurt you, you might shout. Probably this would be enough to frighten him away.
If so, you have actually frightened the stranger away without having to fight him. (78▲)一只鳥也將會做同樣的事. But he expects an outsider almost any time, especially at nesting （筑巢）season. So he is screaming（尖叫）all the time, whether he can see an outsider or not. This screaming is what we call a bird’s song, and it is usually enough to keep an outsider away.
Birds sing loudest in spring when they are trying to attract a mate（同伴）and warn others not to enter the territory of theirs.
You can see that birds have a language of their own. Most of it has to do with attracting mates and setting up territories.
【小題1】根據(jù) (76) 處劃線部分的意思來完成下面句子。（每空一詞，共2詞）

科目：初中英語 來源：2011年江蘇省常州市中考模擬試卷（英語） 題型：閱讀理解

In the summer of 1978 an English man named Steven was driving his tractor through a field of wheat when he discovered something strange. Some of his wheat was lying on the ground. The flattened wheat formed(形成)a circle about six meters across . Around this circle were four smaller circles of flattened wheat.

　 Three years later a farmer who lived nearby discovered almost the same circles in one of his fields. These circles were larger—nearly 15 meters across . That same year , another English farmer discovered three circles of flattened wheat on his land—one large circle between two small circles. During the following years, farmers in England found circles in their fields more and more often.

　 The circles are called “crop circles” because they usually appear in fields of wheat or corn. The wheat in the circles lies on the ground but is never broken; it keeps on growing, and the farmers can later harvest it. Farmers always discover the crop circles in the morning, so the circles probably form at night. They appear only in the months from May to September. What causes the crop circles?

　 At first, people thought that some kids were making them as a joke, or that farmers were making them to attract tourists.(In fact, in 1991, two men said they made the circles themselves, but many scientists don’t believe them.) People tried to copy them: They tried to make circles exactly like the ones the farmers had found. They couldn’t do it. They couldn’t enter a field of wheat without leaving tracks, and they couldn’t flatten the wheat without breaking it.

　 Several times people reported seeing stranger objects near the fields where crop circles later appeared. Many people believe that these crop circles are the messages sent by living things from outer space(外層空間)or the marks left by their spaceships.

　 Scientists who have studied the crop circles try to find out what causes them. In the summer of 1990 some scientists spent three weeks in the part of England where many circles have appeared. They had all the latest high-tech equipment(最新高科技設(shè)備). The equipment—worth 1.8 million dollars—got nothing. But one night, as the scientists were watching a field, crop circles formed in the field behind them, which were quite different from the others. The scientists had neither seen nor heard anything.

　 When Steven discovered the crop circles on his land in 1978, he said, “It was just like something that had landed in the field from the air and gone back up again. I don’t know what to make of these things.”

　 Crop circles have appeared in England, Japan, the United States and Russia. Experts from all over the world have studied them, and they say what Steven said: They don’t know what to make of these things.

1.Which picture is probably the one formed in the field behind the scientists?

2.“Flattened wheat” means ___________.

　　   A. broken wheat             B. lying wheat

　　   C. harvested wheat          D. growing wheat

3.The passage is mainly about something ___________ .

A. that is done by living things from outer space

B. that cannot be solved but found all around the world

C. that cannot be made clear or understood

D. that is discovered and copied by the farmers
