高一(下)学期英语月考试卷 满分:150分时间:100分钟 第一部分(共20小题;每小题2分,满分40分) 第一节阅读理解(共15小题;每小题2分,满分30分) 阅读下列短文,从每题所给的四个选项(A、B、C和D)中,选出最佳选项,并将答案写在答题卡上 A Ireland has had a very difficult history. The problems started in the 16th century when English rulers tried to conquer(征服) Ireland. For hundreds of years, the Irish people fought against the English. Finally, in 1921, the British government was forced to give independence to the south of Ireland. The result is that today there a re two ―Irelands‖. Northern Ireland, in the north, is part of the United Kingdom. The Republic of Ireland, in the south, is an independent country. In the 1840s, the main crop, potatoes,was affected by disease and about 750,000 people died of hunger. This, and a shortage (短缺) of work, forced many people to leave Ireland and live in the USA, the UK, Australia and Canada. As a result of these problems, the population fell from 8.2 million in 1841 to 6.6 million in 1851. For many years, the majority of Irish people earned their living as farmers. Today, many people still work on the land but more and more people are moving to the cities to work in factories and offices. Life in the cities is very different from life in the countryside, where things move at a quieter and slower pace. The Irish are famous for being warm-hearted and friendly, Oscar Wilde, a famous Irish writer, once said that the Irish were ―the greatest talkers since the Greeks‖,Since independence, Ireland has revived(复兴) its own culture of music, language, literature and singing. Different areas have different styles of old Irish songs which are sung without instruments. Other kinds of Irish music use many different instruments such as the violin, whistles, etc. 1.What does the author tell us in Paragraph 1? ________ A. How the Irish fought against the English. B. How two ―Irelands‖ came into being. C. How English rulers tried to conquer Ireland. D. How Ireland gained independence. 2.We learn from the text that in Ireland________. A. food shortages in the 1840s led to a decline(下降)in population B. people are moving to the cities for lack of work in the countryside C. it is harder to make a living as a farmer than as a factory worker D. different kinds of old Irish songs are all sung with instruments 3. What can be the best title for the text? ________ A. Life in Ireland B. A Very Difficult History C. Ireland, Past and Present D. The Independence of Ireland B When newspapers and radio describe the damage caused by a hurricane named Hazel, girls named Hazel are probably teased(取笑)by their friends. To keep out of trouble, the Weather Station says,‖ Any resemblance between hurricane names and the names of particular girls is purely accidental.‖ Some women became angry because hurricanes are given their names, but many other women are proud to see their names make headlines. They don’t even care that they are the names of destructive storms. Because more women seem to like it than dislike it, the Weather Station has decided to continue using girl’s names for hurricanes. In some ways a hurricane is like a person. After it is born, it grows and develops, then becomes old and dies. Each hurricane has a character of its own. Each follows its own path through the world, and people remember it long after it gone .So it is natural to giv e hurricanes’ names, and to talk about them almost if they were alive. 4. What happens to girls named Hazel according to the passage? ________ A. Others often make fun of them. B. The Weather Station look for them. C. They suffer from hurricanes. D. T hey can’t find boyfriend. 5. The underlined word ―resemblance‖ probably means ______ A. trouble B. difference C. sameness D. success 6. According to the passage, which is more reasonable? ________ A. Some women feel unhappy because hurricanes are given their names. B. A lot of women complain of the Weather Station. C. Many women want to be known. D. All the hurricanes are caused by women. 7. It is natural to give hurricane names because ______ A. they become old and die B. each hurricane has its own character C. each hurricane has its own day to come D. all of them should be remembered C Do you want to improve the way you study? Do you feel nervous before a test? Many students say that a lack of concentration (注意力) is their biggest problem. It seriously affects their ability to study, so do their test results. If so, use these tips to help you. Study Techniques ●You should always study in the same place. You shouldn’t sit in a position that you u se for another purpose. For example, when you sit on a sofa to study, your brain will think it is time to relax. Don’t watch TV while you are studying. Experts warn that your concentration may be reduced by 50 percent if you attempt to study in this way. Always try to have a white wall in front of you, so there is nothing to distract (make less concentrated) you. Before sitting down to study, gather together all the equipment you need. Apart from your textbooks, pens, pencils and knives, make sure you have a dictionary. If your study desk or table is needed when you are not studying, store all your equipment in a box beside it. ●Your eyes will become tired if you try to read a text which is on a flat surface. Position your book at an angle of 30 degrees. ●Be r ealistic and don’t try to complete too much in one study period. Finish one thing before beginning another. If you need a break, get up and walk around for a few minutes, but try not to telephone a friend or have something to eat. Test-taking Skills ●All your hard work will be for nothing if you are too nervous to take your test. Getting plenty of rest is very important. This means do not study all night before your test! It is a better idea to have a long-term study plan. Try to make a timetable for your study which lasts for a few months. ●Exercise is a great way to reduce pressure. Doing some form of exercise every day will also improve your concentration. Eat healthy food too. ●When you arrive in the examination room, find your seat and sit down. Breathe slowly and deeply. Check the time on the clock during the test, but not too often. Above all, take no notice of everyone else and give the test paper your undivided attention. 8. Which of the following statements is true according to the passage? A. You sh ould study in a different place every day, so you don’t get bored. B. Your concentration will improve if you study and watch TV at the same time. C. Check the time during the exam at a certain time. D. Staying up all night and studying is tiring, but you will learn a lot using this method. 9. What does the underlined word ―it‖ in the paragraph3 refer to?
