【文章內容簡介】 sts say that the fruit may disappear by 2050. One reason for this is climate（氣候） change. Scientists at the University of Exeter collected data（數(shù)據(jù)） from 27 countries and regions that produce 86 percent of the world39。s bananas. They found that climate change has improved growing conditions in 21 of these countries. In the past 60 years, the average yield（平均產量） has reached tons of bananas per hectare（公頃）. However, if temperatures keep rising, this advantage will disappear. Ten of the countries, including India, the world39。s biggest producer of bananas, will produce fewer bananas. By 2050, the fruit may die out. Shouldn39。t bananas grow more easily if it39。s hotter outside? In fact, the perfect temperature range for growing bananas is between 24 and 32 C. If temperatures get too high, they will stop growing. Diseases are another danger to bananas. Unlike other crops, the bananas we grow e from shoot cuttings（莖段） rather than seeds. This means that all banana plants have the same genotype（基因型）. In other words, if a disease is able to kill one plant, it could kill them all. One serious disease is called Panama. Caused by fungus（真菌） in the soil, it spreads easily. It has spread across South Asia, Africa, the Middle East, and Australia. If one banana plantation（種植園） suffers from the disease, it will take 30 years until it is able to grow bananas again. Scientists have yet to find a cure for this disease.（1）What does the underlined word this in Paragraph 2 refer to? A.People39。s love for bananas.B.The taste of bananas.C.The convenience of eating bananas.D.The future disappearance of bananas.（2）What might happen if temperatures keep going higher? A.More countries will start to grow bananas.B.Bananas will grow better in most countries.C.Bananas will not be able to grow any more.D.Bananas won39。t be as tasty as before.（3）What does Paragraph 5 tell us? A.What diseases bananas may suffer from.B.How bananas are grown.C.How diseases can easily kill bananas.D.Which diseases can kill bananas.（4）The passage is written to ________. A.offer tips for growing bananasB.explain why bananas may die outC.show the difficulties of growing bananasD.describe bananas39。 growing conditions【答案】 （1）D（2）C（3）C（4）B 【解析】【分析】主要講了香蕉可能消失的原因。 （1）推斷題。根據(jù)前句However, British scientists say that the fruit may disappear by ，所以this代指香蕉消失，故選D。 （2）細節(jié)題。根據(jù)However, if temperatures keep rising, this advantage will disappear. Ten of the countries, including India, the world39。s biggest producer of bananas, will produce fewer bananas. By 2050, the fruit may die out可知溫度持續(xù)上升，香蕉將更少，最終可能消失，即不能生長，故選C。 （3）細節(jié)題。根據(jù)Diseases are another danger to ，即疾病是怎樣殺死香蕉的，故選C。 （4）主旨題。根據(jù)全文可知主要講了香蕉可能消失的原因，故選B。 【點評】考查閱讀理解。本文涉及細節(jié)題、推斷題和主旨題三種?？碱}型，細節(jié)題要注意從文中尋找答案；推斷題需要聯(lián)系上下文，推斷出需要的信息；主旨題需要通讀全文，了解大意之后找出中心思想。6．閱讀理解 Grace Murray was born on December 9, 1906 in New York City. In 1928 she finished her education in Vassar College in Maths and Physics. Since 1931, she had been teaching at Vassar and continued her study at Yale University, where she achieved a lot in Maths in 1934. In 1930, Grace Murray married Vincent Foster Hopper. They were happy together for 15 years. She taught at Vassar College until 1943, when she joined the United States Navy（海軍）to help her country during World War Ⅱ.Then she was given a job at the Bureau of Ships Computation Project at Harvard University, where she worked on the Mark series of puters. In 1945, she began to do research in Applied（應用）Physics at Harvard39。s Computation Laboratory. In 1949 she joined the EckertMauchly Computer Corporation and worked with people working in it. Years later, she returned to the Navy. She retired in 1971 but continued teaching for the puter development. Brewster Academy, a school in Wolfeboro, New Hampshire, the United States, gave its puter lab to her for free in 1985, calling it the Grace Murray Hopper Centre for Computer Learning. She had spent her childhood summer at a local family in Wolfeboro. She passed away in her sleep in 1992. Since her death, her workmate Elenor Briggs has been going on with her work. Grace Murray was a great woman and a leader in the puter development. Her work helped improve the use of puter languages. She practised her words Dare and Do in her lifetime.（1）How many years did Grace Murray teach at Vassar? A.About 2 years.B.About 6 years.C.About 12 years.D.About 18 years.（2）Before she joined the United States Navy, what did Grace Murray do at Yale University? A.She studied Maths.B.She researched Applied Physics.C.She developed puter languages.D.She worked on the Mark series of puters.（3）Why did the school in Wolfeboro give its puter lab to Grace Murray for free? A.Because the lab was built with her help.B.Because she once spent some time there.C.Because Wolfeboro was her home town.D.Because she once taught there.（4）The underlined phrase passed away in Paragraph 3 means . A.workedB.diedC.waitedD.dreamed【答案】 （1）C（2）A（3）B（4）B 【解析】【分析】本文介紹了Grace Murray的一生。 （1）細節(jié)題。根據(jù) Since 1931, she had been teaching at Vassar and continued her study at Yale University 從1931年起，她一直在瓦薩任教，She taught at Vassar College until 1943，直到1943年，可知格蕾絲默里在瓦薩教了大概12年書 ， 故選C。 （2）推理題。根據(jù) Since 1931, she had been teaching at Vassar and continued her study at Yale University, where she achieved a lot in Maths in 1934. 自1931年以來，她一直在vassar教書，并繼續(xù)在耶魯大學學習，1934年在那里她在數(shù)學方面取得了很大成績，可知在加入美國海軍之前，格雷斯默里在耶魯大學教數(shù)學 ， 故選A。 （3）推理題。根據(jù)She had spent her childhood summer at a local family in Wolfeboro 她在沃爾夫博羅的一個當?shù)丶彝ザ冗^了童年的夏天 可知沃爾夫博羅的學校免費把它的計算機實驗室給格雷斯默里因為她曾經(jīng)在那里呆過一段時間 ， 故選B。 （4）詞義猜測題。根據(jù) Since her death自從她死后，可知 passed away是去世的意思 ， 故選B。 【點評】考查閱讀理解。本文涉及細節(jié)題、推斷題，詞義猜測題，細節(jié)題要注意從文中尋找答案；推斷題需要聯(lián)系上下文，推斷出需要的信息，詞義猜測題需要根據(jù)上下文提煉相關信息鎖定詞意。7．閱讀理解 A doctor entered the hospital hurriedly after being called in for an important surgery（外科手術）.He found the boy39。s father in the hall waiting
