Everyone knows that we are busy all day. Seldom do we know what is happening both at home and abroad, let alone what we can do for our country. By reading newspapers we can get more information about the world outside. So I think “Friday News Hour” can broaden our mind and enrich our school life. What‘s more, it will help us improve our reading skills. As for my suggestion, I think it’s better to have it twice a week. And we should make a choice about what we‘ll read.

A./; the B.the; the C.a(chǎn); / D.a(chǎn); the 答案:D 解析:考查冠詞。語意為“在中國,為了向老年人表示尊敬,每年有一天被定為敬老日”。day為可數(shù)名詞,在此表示泛指,故其前用a修飾;elders前加the表示老年人。 2.It’s unnatural for a mother to leave her child ______ to enjoy herself. A.a(chǎn)lone B.behind C.out D.off 答案:A 解析:leave...alone表示“丟下……不管”,是一個固定短語。 3.The accident happened on such an evening with strong winds ______ by heavy rain.

A.who B.which C.that D.whom 答案:D 解析:考查定語從句。先行詞是人,又是非限制性定語從句,排除B、C兩項。關(guān)系代詞作介詞of的賓語,所以選whom。 13.(2010·上海春招)The employees ______ that they should renew their contracts within a week. A.a(chǎn)dvise B.have advised C.a(chǎn)re advised D.had been advised 答案:C 解析:考查動詞的語態(tài)。語意:(公司)建議員工在一周內(nèi)簽合同。根據(jù)題意。The employees與advise為動賓關(guān)系,所以應(yīng)該用被動結(jié)構(gòu),故選C項。 14.The old woman ______ her sons and daughters ______ and see her from time to time.

A.to be told B.to tell C.told D.telling 答案:A 解析:“only+不定式”做結(jié)果狀語,表示動作的結(jié)果,該結(jié)果常常出乎意料。根據(jù)句意可判斷出 he是 tell的動作被執(zhí)行者,所以要用不定式的被動式,表示被告知。 Ⅲ .閱讀理解 A What is an animal? For many people, an animal has four legs, a head at the front and a tail at the back. There are, in fact, many different kinds of animals. Some are so small that you cannot see them with human eyes. Some have no head, no mouth and no legs. Some live in the ocean. Some can't fly. They come in thousands of different shapes, sizes and colors. One of the largest groups of animals is the insect group. These animals have six parts to their bodies. Many insects cause human problems. Some carry diseases. Others are a problem because they eat the food that farmers grow. But there are insects, like bees and butterflies, which we need because they help flowers and fruit to grow. Like many of the insects, birds have wings and can fly. There are many different types of birds. Some eat fish and are happy living near rivers or the ocean. Others like to live in the countryside or near towns in flocks of many hundreds and mostly eat insects, and there are birds, like the mountain eagles, which eat meat with their strong sharp beaks. They also have sharp claws on their feet, which are perfect for hunting and killing. Like birds, mammals are warm-blooded, and just as all birds have feathers, all mammals have hair on their bodies. Sometimes you can hardly see the hair. Sometimes the hair is very thick, and then it is called fur. There are several different groups of mammals. There are the cats, which include lions and tigers; there are animals with large front teeth, which include mice and rats; there are the sea mammals, which include the whale, the largest animal in the world. Then there are animals which have two arms and can walk on two legs like monkeys and, of course, humans. Fish and reptiles are cold-blooded animals. Fish live in the ocean, but reptiles usually live on the land. Reptiles are probably the least popular animals. They include the long thin snakes that many people are afraid of. However, some people keep snakes in their homes as pets. 1.According to the passage, an animal ______. A.has four legs, a head at the front and a tail at the back B.is a living thing which is quite strong to humans C.is so small that people can't see it with human eyes D.may come in a different shape, size and color 答案及解析: 1.D。推理判斷題。根據(jù)第一段可知動物大小各異,顏色各異。 2.Why are insects commonly considered to be harmful? A.They are among the largest groups of animals. B.They all have six legs and three parts to their bodies. C.Many of them bring trouble like disease to humans. D.They help flowers and fruit to grow every year. 答案及解析: 2.C。事實細節(jié)題。從第二段Many insects cause human problems.可知,許多昆蟲會給人類帶來麻煩,或傳染疾病或破壞糧食。 3.- 1.請仔細閱讀文檔,確保文檔完整性,對于不預(yù)覽、不比對內(nèi)容而直接下載帶來的問題本站不予受理。
