2根据选项中词的意思,选择合适的一项放入题干进行检查,看是否符合题意。
3如果发现四个选项中有一个以上的选项可以题干构成搭配,那么就要根据句子的意思确定哪一项正确。
4选定答案后,一定整体再检查,看其内容和句子语义是否相符,且符合语法规则。
注:单选我个人主要运用词组,词性,直接翻译和排除法,记住记单词不如记忆短语;以上信息有可能记忆不全,请谅解。
二完型填空10’文章大意关于小孩子在马路玩耍的危险性,由回忆自己童年时代父亲说自己小时候在马路玩的事,再过渡到父亲给外孙讲自己小时候玩耍危险的事给外孙听,以便告诉外孙安全的重要性,层层递进。
此题中考的最多的还是结合篇章词组的运用,一些介词和副词的用法较多,只要稍稍读懂再前后照应读,自然就会选出答案。
同时and前后语法一致也考了两个。
三阅读:15个30分1.忘了,不过挺简单的。
2.故事:从传说中的岛,到谣传中的人到岛屿上生存,且三个人,还带了一些食物,漂流期间,在海上发生了许多事,这时就设涉及到了吃的,这三个人分别就生存的食物提出了不同的利用方法,最后也给读者留下了疑惑。
本片文章就是让读者猜出一些这中间可能发生的许多事并提出问题。
3.关于艺术的,首先提出一种艺术,再提出一种,最后对比,属于比较事物型。
说明:这三篇文章考的没我们想象的那么难,文章提出的五道问答都是与每一段相对应的!所以我认为即使整篇文章有些句子读不懂,你可以跳过,大概知道下文章的意思即可。
有的甚至是文章的原句,只要你找到在哪个位置,一看便找到答案。
如果文章一点也独步懂,办法是你可以先看题,再定位,到筛选再排除。
注:阅读技能1了解语篇和段落的主旨和大意。
2掌握语篇中的事实和主要情节。
3理解上下文的逻辑关系。
4对句子和段落进行推理。
5了解作者的目的、态度和观点。
6根据上下文正确理解生词的意思。
7了解语篇的结论。
8进行信息转换。
四用词的适当形式填空(Using the right word):10’Quality\accustomed\Sense\secrect\communication\art\accent\comfortable \ fashionable\ obvious注:给定的词忘记是10个还是12个了!1.A man should have a Sense of responsibility for his family.2.The men from the two countries met secrectly because they didn’t want the public know their meeting.3.In the online classroom,people communicate with eath other by writing.4.The store-owner was fined $500 for selling goods of low quality.5.He was a great artist;he composed many great songs.注:1-5准确6.She apeaks Japanese with a Chinse accent .7.For obvious reasons ,we have to put off our meeting .8.This hat-style is now liked by fashionble women in paris.9.I have a nice, comfortable room on the hird floor.10.These days we are so accustomed to using e-mail that we seldom use post offices.注:此题考察的就是词性的变化,做题分四点,一是通读给定的词;二是读句子;三是短语;四是翻译顺口。
句子的成分也很重要,什么词性后该接什么词性不该接什么词性,这时就要自己变换了。
应试方法总结:仔细审词,根据语法结构判断空白处应填写哪一种词性;根据所给的词进行转化,使之变为相应的词性,将正确答案放入题中进行检查,根据句子的意思及语法最后确定答案。
五翻译(汉译英):20’1.新法律不适用于海外合资企业。
The new law does not apply to the joint venture overseas.2.看见大海,孩子们开心的大叫起来。
(at the sight of)The childen cried with delight at the sight of the sea .3.这个计划听起来很难,但他决心将它付诸东流。
(put something into practice)Difficult as the plan sounds,he is determined to put it into practice.4.约翰不习惯这儿的新生活,所以打算搬走。
(be accustomed to )John wants to move because he is not accustomed to the new life here.5.只要你经常锻炼,你又会变得健康起来。
(as long as )As long as you get regular exercise ,you will become healthy again.解答思路;首先看所给定的词组,利用英语的句法结构,弄请句子的主干,句子的特殊句式,想到的不会写的再换一种方式表达,保证翻译后通畅。

Reading Comprehension (40 points; 55 minutes)Section 1Directions: Each of the following three passages is followed by some questions. For each question there are four choices. Choose the best answer to eachquestion. Then blacken the corresponding letter on the Answer Sheet. Passage OneQuestions 41 to 45 are based on the following passage.For the past twenty years, poll-takers (民意测验者) have told us that the vast majority of Americans report that they are “satisfied” or “very satisfied” with their jobs. But, when the surveys pose a slightly different question—“If you had to do it over, would you choose the same line of work?”—sixty percent of working Americans say they would choose another occupation. This seems to tell us that Americans feel that they are supposed to like their jobs but, in reality, they don’t. Most of us are stuck in jobs we’d prefer not to have. And some of us actually hate what we do.How does this happen in a land where citizens are presumably free to do, and become, anything they want? First of all, some of us didn’t deliberately choose our jobs but simply fell into them. Later, there was never time to find out what we really wanted to do.Another reason people dislike their jobs is the result of a change in the American economy. A hundred years ago most Americans worked for themselves on farms or in small stores and workshops. Now, less than 10 percent of us are self-employed. Many of us work as cogs (轮牙) in the wheels of giant corporations. We don’t make a finished product with our own hands, and we feel that we are totally replaceable parts in the machine. Social scientists say that the happiest workers are the ones who are their own bosses—business owners, executives, and professionals. Working for a big company often results in a sense of powerlessness and malaise. Finally, being a member of the baby boom generation increases the chances of job dissatisfaction. In the struggle for careers among the members of this large population “bulge”, many people are losing out in the competition. These individuals may never achieve the standard of living their parents achieved, or go as far up the success ladder as they had ho ped. The result is bitterness, and a feeling of being trapped in a “nowhere” job.41. The best title for this selection is __________.A. Job SatisfactionB. Why People Hate Their JobsC. Nowhere JobsD. A Change in the Workplace42. Which sentence best expresses the main idea of the selection? __________.A. Job burnout is a growing problemB. Large companies provide many benefits for workersC. Workers are unhappy because they no longer work with their handsD. There are several reasons why workers are unhappy with their jobs43. According to the passage, the majority of Americans __________.A. would choose another occupation if they could begin againB. are self-employedC. feel that they are supposed to dislike their jobsD. work in factories44. The author implies that __________.A. job dissatisfaction is a sign of lazinessB. the baby-boomers despise their parentsC. polls can be misleadingD. working for a corporation is very satisfying45. The word “malaise” (Line7, Para. 3) means __________.A. depressionB. fulfillmentC. contentmentD. significancePassage TwoQuestions 46 to 50 are based on the following passage.Most forest fires are caused by human carelessness or ignorance. Forest fire prevention, therefore, is mainly a problem of creating better understanding of the importance of forests, an awareness of the danger of fire in the woods, and a sense of personal responsibility to safeguard the forests from danger. This is not an easy job.Careless smokers are responsible for thousands of forest fires each year. Many of these are started when cigarette butts (烟蒂) and matches are thrown from automobiles. Others are caused by hunters, hikers (徒步旅行者), fishermen, or woods workers who are careless in disposing of their smoking materials. The Forest Service has posted rules in many of the National Forests that prohibit smoking except in certain designated areas. Many of the states have laws against throwing lighted materials from automobiles. The prevention of smoker-caused fires, however, depends upon changing the attitudes and behavior of millions of people who smoke in hazardous areas.The most important natural cause of fire is lightning (闪电). This accounts for 11 percent of forest fires on protected land for the entire nation. In the Western States, lightning causes a much higher percentage of fires than it does in the East.Advances in knowledge of fire weather are helping forest protection forces to know when to be alert to lightning-caused fires. Adequate and well-equipped forces can control them quickly and hold the damage to a minimum. Experiments in “seeding” thunder clouds to pre vent or control the lightning itself have been in process for many years, but new breakthroughs are needed for any significant reduction in the fires lightning starts.46. This passage is chiefly about __________.A. smoking in forestsB. changing the attitudes and behavior of millions of peopleC. the chief causes of forest fires and their preventionD. advances in knowledge of fire weather47. Preventing smoker-caused forest fires is mainly a problem of __________.A. building the proper knowledge and habits in human beingsB. safeguarding the forests from fireC. posting rules in forestsD. holding the damage to a minimum48. Lightning-caused fires can be controlled quickly by __________.A. holding the fire damage to a minimumB. people who have changed their attitudes and behaviorC. enough fire fighters with good fire-fighting devicesD. carrying out experiments in “seeding” thunder clouds49. “Alert to” (Line 2, Para. 4) most probably means __________.A. aware ofB. watchful forC. responsible forD. busy with50. Which of the following statements is true according to the passage? __________.A. It is difficult to prevent forest firesB. Smoking is allowed only in certain forestsC. 11% of the forest fires in the Western States are caused by lightningD. Experiments in “seeding” thunder clouds have helped reduce lightning-causedforest firesPassage ThreeQuestions 51 to 55 are based on the following passage.Some years ago industries had more freedom than they have now, and they did not need to be as careful as they must today. They did not need to worry a lot about the safety of the new products that they developed. They did not have to pay much attention to the health and safety of the people who worked for them. Often new products were dangerous for the people who used them;often conditions in the work place had very bad effects on the health of the workers.Of course sometimes there were real disasters(灾难) which attracted the attention of governments and which showed the need for changes.Also scientists who were doing research into the health of workers sometimes produced information which governments could not ignore.At such times, there were inquiries into the causes of the disasters or the problems. New safety rules were often introduced as a result of these inquiries;however, the new rules came too late to protect the people who died or who became seriously ill.Today many governments have special departments which protect customers and workers. In the U. S., for example, there is a department which tests new airplanes and gives warnings about possible problems. It also makes the rules that aircraft producers must follow. Another department controls the foods and drugs that companies sell.A third department looks at the places where people work,and then reports any companies that are breaking the laws which protect the health and safety of workers.

(对的在答题卡上涂A, 错的在答题卡上涂B) Passage FourQuestions 56 to 60 are based on the following passage.When someone who is in good health dies suddenly, there is usually an inquest.An inquest is a kind of court inquiry. The person in charge of an inquest is called a coroner (验尸官). His job is to find out exactly how a person died.If there is nothing suspicious (怀疑的) about the death, he would decide that the person died from natural causes or an accident. If, however, he is suspicious, he may decide that the person’s death was caused by a person or persons unknown.At one inquest, the coroner was trying to find out exactly what had caused the death of a local businessman, Henry Smith.The man’s widow was offering the evid ence. She was very upset and had to stop from time to time.The coroner did not want to upset her more than necessary, but he had to find out the truth. There were questions he had to ask her.“Mrs. Smith, I know this is too much for you,” he said, “but I want you to think very carefully and then answer my questions.”“Y ou and your husband were having dinner at home. Is that correct?”“Y es.”“Suddenly he fell to the floor.”“Y es.”“Did he say anything?”The widow lowered her head.“Please, Mrs. Smith, you must answer the question. What were his last words?” The widow took a deep breath and then spoke. “He said,” she whispered, “I’mnot surprised you were charged only 50 cents for that seafood we had for dinner.”( ) 56. An inquest is done in one’s home.( ) 57. The coroner decides on the nature of a person’s death.( ) 58. The coroner was very careful in asking Mrs. Smith questions so as not toupset her.( ) 59. Mrs. Smith was quick to tell the truth.( ) 60. The bad seafood was responsible for Mr. Smith’s death.Paper TwoPart IV. Short Answer Questions (10 points; 15 minutes)Directions: In this part there is a short passage with five questions or incompletestatements. Read the passage carefully. Then answer the questions or complete thestatements in the fewest possible words (not exceeding 10 words) . Write your answers on the Answer Sheet of Paper Two. (请将此部分的答案写在试卷二的答题纸上)Questions 61 to 65 are based on the following passage.All of us communicate with one another nonverbally as well as with words. Mostof the time we’re not aware that we’re doing it. We gesture with eyebrows or hands, meet someone else’s eyes and look away , or change positions in a chair. These actions we assume are occasional. However in recent years researchers have discovered that there is a system to them almost as consistent and understandable as language.One important kind of body language is eye behavior. Americans are carefulabout how and when they meet one another’s eyes. In our normal conversation, each eye contact lasts only about a second before one or both of us look away . When two Americans look searchingly into each other’s eyes, they become more intimate. Therefore, we carefully avoid this, except in suitable situations.Researchers who are engagedin the study of communication through bodyAmovement are not prepared to spell out a precise vocabulary of gestures. When anAmerican rubs his nose, it may mean he is disagreeing with someone or refusingsomething. But there are other possible interpretations, too. Another example: when a student in conversation with a professor holds the older man’s eyes a little longer than usual it can be a sign of respect, it can be a challenge to the professor’s authority, or itcan be something else entirely. The researchers look for patterns in the situation, notfor a separate meaningful gesture.Communication between human beings would be just dull if it were all done with words.61. How can people communicate with each other besides language?_________________________________________________________________ 62.Like language, gesture is___________________________________________________.63.According to the second paragraph, an American will feel uncomfortable ifsomeone__________________________________________________________________ 64.If a student holds his professor’s eyes a little longer in a conversation, what can itmean?__________________________________________________________________ 65.What is the main idea of the passage?__________________________________________________________________ Part V.
