2019-2020年高三11月周考英语试题 缺答案（时间120分钟，满分150） xx.11第卷（共70分）. Grammar and vocabulary（20%）Section ADirections: After reading the passages below, fill in the blanks to make the passages coherent and grammatically correct. For the blanks with a given word, fill in each blank with the proper form of the given word; for the other blanks, use one word that best fits each blank.In most industrialized countries about 105 boys are born for every 100 girls, for a ratio of 1.05, known as the secondary sex ratio, or SSR; the primary sex ratio is the ratio at conception. This is often expressed as the percentage of boys among all births, or about 51.2 percent. The percentage of males among all births is not fixed, however. Since the 1950s and 1960s the overall SSR 25 (decline) in the U.S., Canada and several European countries, there are also both personal and environmental factors that affect the average sex ratio. 26 chance of having a boy appears 27 (decline)with the mothers age, the fathers age and the number of children the family already has. These effects are small. One study in Denmark found that the SSR of children born to fathers younger than 25 was 51.6 percent, which decreased 28 51.0 percent among children of fathers at least 40 years of age. Therefore it is unlikely that the declining SSR in many countries results solely from large-scale changes in such personal factors. With regard to environmental factors, improved prenatal and obstetrical care during the first part of the 20th century is largely responsible for an 29 (increase) SSR over this period in many countries. The male fetus is more susceptible to loss in the womb than is the female fetus, so with more conceptions reaching term, proportionally more males are born. It is difficult to discern how much of the decrease in sex ratio since the 1950s arises from contaminants in the environment. What is known is that drug use, high occupational exposures and environmental accidents 30 affect SSR. For example, hopeful mothers 31 (take) clomiphene citrate (Clomid) for infertility bore babies with an SSR of only 48.5 percent. Workers producing 1,2-dibromo-3-chloropropane (DBCP), a chemical used to kill worms in agriculture, experienced even larger decreases in the number of male babies. Effects of DBCP on sperm quality 32 (discover) incidentally when male workers found that they were unable to father children. After the exposure ended, male workers experienced some recovery of sperm quality and 36 children were born to 44 workers. Of these 36 children only 10 were boys-an SSR of just 27.8 percent. These dramatic changes resulting from extreme exposures raise the concern that chemicals in the environment at 33 (low) concentrations may also change the SSR by exposing people over longer periods of time. For example, there are reports that parental exposure to polychlorinated biphenyls (PCBs) and mercury, each of which is widely distributed in the environment, can affect the sex ratio. 34 (confirm) such effects will take careful work on large populations, but the results may be quite important.Section B（8%）Directions: plete the following passage by using the words in the box.

We will take students into artistic venues.”“We hope that our children will enjoy visiting theaters, galleries and museums after work to make their life more colorful when they grow up,” she added.“Most theaters for 38 are empty on weekdays, which means our schools have not made good use of them,” said Cai Jinping, a political adviser and director of the Childrens Theater of China Welfare Institute. ”Artistic education should not be 39 to music or art classes in schools,” Cai said.“We have to bring children into professional venues to 40 the plete presentation of real and elegant arts in person.”Wang Yang, principal of Caoyang No 2 High School, weled the plan, saying that Chinese students do not enjoy the same standard of arts 41 extracurricular activities that are taken for 42 in western countries.“Its important to cultivate artistic tastes in our children when they are young. Listening to a concert when being taught about a musician, or seeing an exhibition after learning about the artist, would be really helpful in understanding the arts,” he told Shanghai Daily.“But most students focus on lessons at school and only some who are members of student artistic groups have the opportunity to visit artistic venues 43 .”He said that some parents bring children to concerts or exhibitions on weekends, but not every family can afford it. “Visits to galleries and theaters are cheaper when they are organized by schools,” Wang said, adding that the government could help to improve Shanghais cultural 44 by building new arts venues.Reading prehension（45%）Section ADirections: For each blank in the following passage there are four words or phrases marked A,B,C and D.

Each passage is followed by several questions or unfinished statements. For each of them there are four choices marked A, B, C and D. Choose the one that fits best according to the information given in the passage you have just read.(A) The case for college has been accepted without question for more than a generation. All high school graduates ought to go, says conventional wisdom and statistical evidence, because college will help them earn more money, bee better people, and learn to be more responsible citizens than those who dont go. But college has never been able to work its magic for everyone. And now that close to half our high school graduates are attending, those who dont fit the pattern are being more numerous, and more obvious. College graduates are selling shoes and driving taxis; college students interfere with each others experiments and write false letters of remendation in the intense petition for admission to graduate school. Other find no stimulation in their studies, and drop outoften encouraged by college administrators. Some observers say the fault is with the young people themselvesthey are spoiled and they are expecting too much. But that is a condemnation of the students as a whole, and doesnt explain all campus unhappiness. Others blame the state of the world, and they are partly right. We have been told that young people have to go to college because our economy cant absorb an army of untrained eighteen-year-olds. But disappointed graduates are learning that it can no longer absorb an army of trained twenty-two-year-olds, either. Some adventuresome educators and watchers have openly begun to suggest that college may not be the best, the proper, the only place for every young person after the pletion of high school. We may have been looking at all those surveys and statistics upside down, it seems, and through the rosy glow of our own remembered college experiences. Perhaps college doesnt make people intelligent, ambitious, happy, liberal, or quick to learn thingsmay it is just the other way around, and intelligent, ambitious, happy, liberal, quick-learning people are merely the ones who have been attracted to college in the first place. And perhaps all those successful college graduates would have been successful whether they had gone to college or not. This is heresy to those of us who have been brought up to believe that if a little schooling is good, more has to be much better. But contrary evidence is beginning to mount up.60.According to the author, _.A.people used to question the value of college education.B.people used to have full confidence in higher education.C.all high school graduates went to college.D.very few high school graduates chose to go to college.61.In the 2nd paragraph, those who dont fit the pattern refer to_.A.high school graduates who arent suitable for college education.B.college graduates who are selling shoes and driving taxis.C.college students who arent any better for their higher education.D.high school graduates who failed to be admitted to college.62.The dropout rate of college students seems to go up because_.A.young people are disappointed with the conventional way of teaching at college.B.many people are required to join the army.C.young people have little motivation in pursuing a higher education.D.young people dont like the intense petition for admission to graduate school.63.According to the passage, the problems of college education partly originate in the fact that_.A.society cannot provide enough jobs for properly trained graduates.B.High school graduates do not fit the pattern of college education.C.Too many students have to earn their own living.D.College administrators encourage students to drop out.64.In this passage the author argues that_.A.more and more evidence shows college education may not be the best thing for high school graduates.B.College education is not enough if one wants to be successful.C.College education benefits only the intelligent, ambitious, and quick-learning people.D.Intelligent people may learn quicker if they dont go to college.BCCAA(B) Bugs Bunnys Hoping Carrot Hunt In this game you are Bugs Bunny. and your goal is to reach the finish line.

American-owned intellectual property, say, may be uploaded in one country and downloaded in a second, via a website whose puters are in a third, operated by anonymous enthusiasts (or criminals) from goodness-knows-where. So whom do you sue, and in which courts? The Stop Online Piracy Act (SOPA), now before Americas Congress, is the latest of many recent attempts to defend property rights on the internet. The bill aims to cut off Americans access to foreign pirate websites by squeezing intermediaries. Rights-holders, such as Hollywood film studios, will be able to request that a credit-card firm or advertising network stop doing business with a foreign site; or ask a search engine to take down links to the site; or ask an internet-service provider to block the sites domain name, making it harder to reach. The intermediary then has just five days to ply or rebut the plaint; after that the rights-holder can go to court. This would rope intermediaries into law enforcement to an unprecedented degree, and give rights-holders exceptional power. Critics of the bill say that takedown requests and court orders will swamp smaller firms and start-ups. They say that blocking entire websites via their domain name smacks of censorship, and that determined downloaders will anyway find the block easy to bypass. Two mighty coalitions have formed around SOPA. Supporting the bill are not only film studios and music labels, but also drug firms and other manufacturers. Though SOPA itself does not affect them, they have a big interest in fighting any kind of intellectual-property infringement. On the other side are internet panies, technology investors and digital activists, who share an interest in disrupting business models and a dislike for anything that smacks of old-fashioned regulation. But the real row is about how content should be distributed and paid for. The bills supporters want this to change as slowly as possible, so they have time to adapt. Opponents want see more rapid changes in business models to speed up overdue innovation: cheaper pricing in poor countries, more use of on-demand digital services, less exclusivity in distribution, and ultimately, less reliance on selling albums and DVDS. Yet self-interest is at work on both sides: many of the bills critics are trying to create just these kinds of business.67. Why is it hard to stop or manage online piracy? A. There are not enough executive organizations. B. The congress doesnt pay attention to this problem. C. It is difficult to identify the offenders D. No court can deal with the cases.68. We can infer from paragraph 2 that the bill_. A. Will prohibit advertising network from doing business with foreign sites B. Is designed to make intermediaries unreadable by blocking their domain names. C. Will require a search engine to cut off links to an intermediary D Intends to fight against online intellectual property infringement. 69. Internet panies, technology investors and digital activists would most probably agree that . A. People should oppose illegal copying and sharing of copyrighted material B.
