【文章內容簡介】 in Africa are destroyed. C． The whole mankind bees extinct. D． The visit of the et results in wars. 答案： C 辨別正誤題。據(jù)第三自然段的描述可知， A、 B、 D均符合本文所假想的事實，只有 C不符。文中 “No more than 10 million people have survived” 一句意為 “ 只有一千萬人幸存下來 ” ，而 C項說全人類都滅絕了。顯然與文章不符。題干要求找出不對的選項。 37． Why does the author mention dinosaurs at the end of the passage? A． Because they could only live in the warm climate. B． Because they once dominated the earth. C． Because their extinction indicates future disasters. D． Because dinosaurs and humans never live in the same age. 答案： C 推理判斷題。第三段中，作者描述假想的人類災難 ?? 最后一段提到生活在地球上的恐龍在 65 million years ago 突然消失 (即滅絕 )，許多 科學家相信地球曾受到過外空星體碎片的襲擊，故而導致恐龍絕種。由此暗示人類未來的災難。 38． In writing the passage, the author intends to________. A． give an accurate description of the possible disaster in the future B． prove that humans will sooner or later be destroyed C． tell the historical development of the earth D． warn of a possible disaster in the future 答案： D 觀點態(tài)度題。本題要求考生推測作者意圖。作者通過一段幻想的災難和一段地球歷史上出現(xiàn)過的恐龍絕跡的事實以及科學家們分析恐龍絕跡的原因，來警示人類未來可能發(fā)生的災難。 39． It can be concluded that the passage is most probably part of a(n)________． A． horror story B． news report C． research paper D． article of popular science 答案： D 推理判斷題。據(jù)全文大意，又據(jù)文章的性質，可判定 D為最佳選項。 A、 B、 C均不太妥當。 B (2021 山西省大同高一下學期期中 ) Satellites are an important part of our ordinary lives. For example, the information for weather forecasts is sent by satellite. Some satellites have cameras which take photographs of the Earth to show how clouds are moving. Satellites are also used to connect our international phone calls. Computer connections of the World Wide Web and Inter also use satellites. Many of our TV programs e to us through satellites. Airplane pilots also sometimes use a satellite to help them find their exact location. We use satellites to send television pictures from one part of the world to another. They are usually 35, 880 kilometers above the equator. Sometimes we can see a satellite in the sky and it seems to stay in the same place. This is because it is moving around the world at 11,000 kilometers an hour— exactly the same speed that the earth rotates. A satellite must orbit the Earth with its antennae (天線 ) facing the earth. Sometimes, it moves away from its orbit. So there are little rockets on it which are used to put the satellite back in the right position. This usually happens about every five or six days. Space is not empty! Every week, more and more satellites are sent into space to orbit the Earth. A satellite usually works for about 10－ 12 years. Satellites which are broken are sometimes repaired by astronauts or sometimes brought back to Earth to be repaired. Often, very old or broken satellites are left in space to orbit the Earth for a very long time. This is very serious because some satellites use nuclear power and they can crash into each other. 40． Which of the following is NOT done by satellites according to the passage? A． Sending information for weather forecast. B． Taking photographs of the Earth. C． Sending TV pictures. D． Providing food for airplane pilots. 答案： D 從第一段可知， A、 B項的內容都是衛(wèi)星的功能，從第三段可知，衛(wèi)星還可以發(fā)送電視畫面，而 D項內容文中并未提及。 41． What39。s the speed the earth rotates at? A． 35,880 kilometers per hour. B． 335,880 kilometers per hour. C． 11,000 kilometers per hour. D． 110,000 kilometers per hour. 答案： C 從第三段的 This is because it is moving around the world at 11,000 kilometers an hour— exactly the same speed that the earth C項為正確答案。 42． What does the underlined word “This” in the 3rd paragraph refer to? A． A satellite. B． A little rocket. C． A satellite seems to stay in the same place in the sky. D． The satellite puts the rockets in the right position. 答案： C 上一句話的意思是：有時候我們看到天空中的衛(wèi)星好像呆在同一個地方，這是因為 ?? ，故本題答案為 C。 43． Which is true of satellites? A． A satellite usually works for about 10－ 12 years. B． Every time a satellite gets broken, it is brought back to the Earth to be repaired. C． A broken satellite is never left in space. D． They often crash into each other. 答案： A 從最后一段的第三句話可知 A項正確。 C Brian arrived at the San Francisco airport two hours before the flight to Paris. He was wearing three shirts, a jacket， two pairs of socks， a pair of shorts, and two pairs of jeans. He was carrying one small backpack， which was very full, but he didn39。t have any other luggage. Brian needed to meet a man named Tony before he checked in for his flight. He found Tony near the Air France counter. Tony gave him a round173。trip ticket and a small package. “Give this package to Jean Paul at the airport in Paris. He will have a sign with your name on it. I think you can find him easily， ” Tony said ， “You don39。t have any luggage, right？ ” “Only this backpack ， ” Brian answered ， “You said I could bring one carry173。on bag.” “That39。s right. One carry173。on bag is f
