阅读理解解题技巧


是非判断题是细节题的一种,是要求考生选出与文章内容相符(三误一正)或不相符的一项(三正一误)。题干中常有TRUE,NOT TRUE或EXCEPT等,考生务必要留意是否有NOT或EXCEPT,否则就容易出错。常见的提问方式有:
Which of the following is (NOT) true?
The author mentions all of the items listed below except...
信息点可能在某句、某段,较容易找到;但信息点也可能分散在几段甚至全文,相对就较难了。当分散在几段或全文时,按理需要花较多时间在各段落找到相关句。若要到全文中去一一查证四个选项,效率太低。因此我们可以首先对所有选项作逐一分析,根据常理或自己的知识结构,看看哪一选项最有可能是答案。如问哪一个true,就把四个中最可能正确的一项挑出来首先去查证;如问哪一个NOT true,就把四个中最可能是错误的一项挑出来首先去查证。用这一方法,最多查证两项,答案就会出来。
另外还有一招,假如我们发现四个选项中有两个选项的意思矛盾或相反,那么其中之一很可能是正确答案,就立马排除了另两个选项,只需从这两个选项中选一个去验证。这样不但节省了时间,更大大提高了正确率。
(2015·福建卷)阅读下列选段,然后从所给的A、B、C和D项中,选出最佳选项。
Food festivals around the world
Stilton Cheese Rolling
May Day is a traditional day for celebrations,but the 2,000 English villagers of Stilton must be the only people in the world who include cheese rolling in their annual plans.Teams of four,dressed in a variety of strange and funny clothes,roll a complete cheese along a 50-metre course.On the way,they must not kick or throw their cheese,or go into their competitors' lane(赛道).Competition is fierce and the chief prize is a complete Stilton cheese weighing about four kilos(disappointingly,but understandably the cheeses used in the race are wooden ones).All the competitors are served with beer or port wine,the traditional accompaniment for Stilton cheese.
Fiery Foods Festival—The Hottest Festival on Earth
Every year more than 10,000 people head for the city of Albuquerque,New Mexico.They come from as far away as Australia,the Caribbean and China,but they all share a common addiction—food that is not just spicy(辛辣),but hot enough to make your mouth burn,your head spin and your eyes water.Their destination is the Fiery Food and BBQ Festival which is held over a period of three days every March.You might like to try a chocolate-covered habanero pepper—officially the hottest pepper in the world—or any one of the thousands of products that are on show.But one thing's for sure—if you don't like the feeling of a burning tongue,this festival isn't for you!
La Tomatina—The World's Biggest Food Fight
On the last Wednesday of every August,the Spanish town of Bun~,ol hosts La Tomatina—the world's largest food fight.A week-long celebration leads up to an exciting tomato battle as the highlight of the week's events.The early morning sees the arrival of large trucks with tomatoes—official fight-starters get things going by casting tomatoes at the crowd.
The battle lasts little more than half an hour,in which time around 50,000 kilograms of tomatoes have been thrown at anyone or anything that moves,runs,or fights back.Then everyone heads down to the river to make friends again—and for a much-needed wash!
1.In the Stilton cheese rolling competition,competitors on each team must________.
A.wear various formal clothes
B.roll a wooden cheese in their own lane
C.kick or throw their cheese
D.use a real cheese weighing about four kilos

4.Which of the following is TRUE according to the passage?
A.The chief prize for the Stilton cheese rolling competition is beer or port wine.
B.More than 10,000 Chinese take part in the Fiery Food and BBQ Festival.
C.Thousands of spicy foods are on show in the Fiery Food and BBQ Festival.
D.An exciting tomato battle takes place at the beginning of La Tomatina.

第一节 阅读理解
阅读下面的短文,从每题所给的A、B、C和D项中选出最佳选项。
Here is some must-know information from a handbook on how people behave in doing business in some countries.
In Brazil
Brazilians are warm and friendly.They often stand close when talking and it is common for them to touch the person on the shoulder.People often greet each other (particularly women) with light cheek kisses.Schedules tend to be flexible,with business meetings sometimes starting later than planned.But to be safe,be on time.Meals can stretch for hours—there's no such thing as rushing a meal in Brazil.Lunches also can start in the mid to late afternoon.Brazilians are social,preferring face-to-face communication over emails or phone calls.
In Singapore
Singaporeans shake hands when they meet and often also greet each other with a small,polite bow.Business cards should be offered and received with two hands.Arriving late is considered disrespectful.So be on time.Efficiency(效率) is the goal,so meetings and dealings often are fast-paced.Singaporeans are direct in their discussions,even when the subject is about money.Rank is important and authority is respected.This determines how people interact in meetings.For example,people avoid disagreeing outright with someone with a higher rank.
In the United Arab Emirates
In the UAE,status is important,so the most senior or oldest should be greeted first with their titles.The handshake seems to be longer than elsewhere.So do not pull away from the handshake.Women should cover themselves when it comes to dress.Men also tend to be covered from neck to elbows(肘部) and down to the knees.People do not avoid entertaining in their homes,but they also hold business meals at restaurants.Touching or passing food or eating with your left hand is to be avoided.When meetings are one-to-one,if your host offers you coffee,you should refuse.It might seem odd,but it is a cultural tradition.Coffee should only be accepted if it is already set out or presented.
In Switzerland
The Swiss tend to be formal and address each other by last name.They also are respectful of private lives.You should be careful not to ask about personal topics.Punctuality (守时) is vital,something that comes from a deep respect for others' time.Arrive at any meeting or event a few minutes early to be safe.They also have clear structure in their companies.Higher-ups make the final decisions,even if others might disagree.Neat,clean dress is expected.The Swiss follow formal table manners.They also keep their hands visible at the table and their elbows off the table.It is polite to finish the food on your plate.
1.The passage is mainly about ________.
A.communication types
B.the workplace atmosphere
C.customs and social manners
D.living conditions and standards
2.Why do Singaporeans avoid arguing with their boss?
A.They put efficiency in the first place.
B.They dislike face-to-face communication.
C.They want to finish meetings as quickly as possible.
D.They are supposed to obey the person of a higher rank.
3.In the UAE,when should you refuse the coffee if it is offered?
A.When greeting seniors.
B.When meeting the host alone.
C.When attending a presentation.
D.When dining with business partners.
4.In which country do people care about where to put their hands at the dinner table?

第三节 语法填空
阅读下面材料,在空白处填入适当的内容(不多于3个单词)或括号内单词的正确形式。
(2014·课标全国Ⅰ卷)Are you facing a situation that looks impossible to fix?
In 1969,the pollution was terrible along the Cuyahoga River near Cleveland,Ohio.It 1.________(be)unimaginable that it could ever be cleaned up.The river was so polluted that it 2.________(actual)caught fire and burned.Now,years later,this river is one of 3.________most outstanding examples of environmental cleanup.

Maybe you are facing an impossible situation.Maybe you have a habit 7.________is driving your family crazy.Possibly you drink too much or don't know how to control your credit card use.When you face such an impossible situation,don't you want a quick fix and something to change immediately?
While there are 8.________(amaze) stories of instant transformation,for most of us the 9.________(change) are gradual and require a lot of effort and work,like cleaning up a polluted river.Just be 10.________(patience)
语篇解读:本文以花费多年时间解决河流污染为例来告诫我们:当我们面临貌似不可能改善的情况时,一定要有耐心,变化是循序渐进的,是需要付出很多努力的。
1.解析:考查时态。句意:当时很难想象这条河流能够被清理干净。上一句提到In 1969,所以此处要用一般过去时。
答案:was
2.解析:考查词性转换。该空处修饰动词,所以要用副词形式actually,意为“事实上,实际上”。
答案:actually
3.解析:考查冠词。句意:多年之后,现在这条河流成为了环境清理最杰出的例子之一。此处是“one of+the+形容词最高级+可数名词复数”结构。
答案:the
4.解析:考查连词。句意:但是这条河流不是在几天内改变的,甚至也不是在几个月内改变的。or用于否定中,意为“也不,也不是,也没有”。
答案:or
5.解析:考查非谓语动词。句意:减少工业污染和净化河水花费了多年的工作。It takes/took...to do sth.做某事花费……,为固定句式,故填动词不定式to reduce。该句式中it是形式主语,不定式短语才是真正的主语。
答案:to reduce
6.解析:考查形容词的比较级。句意:最后,辛苦的工作得到了回报,现在河水比以前干净多了。根据句中比较级的标志词than可知,该空应用比较级,故填cleaner。
答案:cleaner
7.解析:考查定语从句。句意:可能你有一种让家人发疯的习惯。根据句子结构可知该空应是定语从句的关系词,先行词是a habit,关系词在定语从句中作主语,故填that或which。
答案:that/which
8.解析:考查词性转换。虽然有一些令人吃惊的快速改观的故事,但是对我们大部分来说,变化是循序渐进的,并且也是需要很多努力和工作的。设空处修饰表示“事物”的名词stories,应该用形容词形式amazing(令人吃惊的)。不能用amazed(感到吃惊的)。
答案:amazing
9.解析:考查名词。定冠词the后面应该填名词,根据谓语动词are和require可知应是名词的复数形式,故填changes。
答案:changes
10.解析:考查词性转换。句意:要有耐心。此处be动词后面应是形容词作表语,故填patient(耐心的)。
答案:patient
第四节 短文改错
