题目内容

15．If Nina _____ that her husband would go to the bus stop to meet her，she wouldn't have walked back home．（　　）

A．

knows

B．

knew

C．

has known

D．

had known

分析如果Nina早知道她的丈夫会去汽车站接她，她就不会走着回家了．

解答答案：D
分析句意可知，本题考查的是虚拟条件句，当条件句表示与过去相反的事实时，要用过去完成时即：had+done的形式，主句谓语用"should （would，could，might）+have+done；根据主句的意思：她就不会走着回家了．可知，之前她不知道她的丈夫会去汽车站接她，此处从句表达了与过去相反的事实，所以要用虚拟语气即：had+done的形式．故选D．

点评本题考查的是虚拟条件句．需要注意牢记以下用法：（1）表示与现在事实相反，条件从句的谓语用过去式（be通常用were），主句谓语用"should （would，could，might）+动词原形"；（2）与过去事实相反，条件从句的谓语用过去完成时（had+过去分词），主句谓语用"should （would，could，might）+have+done"；（3）与将来事实相反，条件从句的谓语用过去式（be通常用were），主句谓语用"should （would，could，might）+动词原形"．

3．For those who are tired doing the laundry，Samsung has found an answer：a washing machine that can tell you when your laundry is done via a smartphone app（application）．
Strange though it may seem-"my wife already does that"was a common response among attendees viewing the device when it was introduced at the Consumer Electronics Show （CES） this week-Samsung is just one of many appliance makers racing to install （安装） a large number of internet-connected features in machines in an effort to make them"smart"．
Last year，it was a refrigerator that tweeted．This year，it's Wi-Fi-enabled laundry machines and fridges that can tell you when your groceries are going bad．
The washers and dryers，available starting in the spring，connect to any smartphone through a downloadable application．The phone can then be used as a remote control，so the machines can be turned on and off while their owners is at work or on the bus．
Samsung says it's not just something new-the app connection actually has some practical uses．
"If you started to dry clothes in the morning and forgot to take them out，you can go to your phone and restart your dryer for the time when come home，so your clothes are refreshed and ready to go，"said spokesperson Amy Schmidt．
The company also says that with electricity rate（电价）varying depending on the time of day，more control over when the machines are used can help save money．
Perhaps，but what they will probably really accomplish is what all good technologies do-enable laziness．Rather than getting up to check on whether the laundry is done，users will instead monitor it on their phones while watching TV．

A．The machine will be a big success．
B．their wives like doing the laundry．

C．smartphone can shorten the drying time
D．we should refresh clothes back at home
75．What is the main idea of the last paragraph？C．
A．The laundry should be frequently checked
B．Lazy people like using such machines
C．Good technologies also cause problems
D．Television may help do the laundry．

20．

Our brains work in complex and strange ways. There are some people who can calculate the day of the week for any given date in 40,000 years, but who cannot add two plus two. Others can perform complex classical piano pieces after hearing them once, but they cannot read or write.

Dr. J. Langdon Down first described this condition in 1887. He called these people idiot savants. An idiot savant is a person who has significant mental injury, such as in autism (自闭症) or retardation. At the same time, the person also exhibits some extraordinary skills, which are unusual for most people. The skills of the savant may vary from being exceptionally gifted in music or in mathematics, or having a photographic memory. One of the first descriptions of a human who could calculate quickly was written in 1789 by Dr. Benjamin Rush, an American doctor. His patient, Thomas Fuller, was brought to Virginia as a slave in 1724. It took Thomas only 90 seconds to work out that a man who has lived 70 years, 17 days, and 12 hours has lived 2,210,500,800 seconds. Despite this ability, he died in 1790 without ever learning to read or write.

Another idiot savant slave became famous as a pianist in the 1860s. Blind Tom had a vocabulary of only 100 words, but he played 5,000 musical pieces beautifully.

In the excellent movie Rain Man, made in 1988 and available on video cassette, Dustin Hoffman plays an idiot savant who amazes his brother played by Tom Cruise, with his ability to perform complex calculations very rapidly.

Today we more clearly recognize that the idiot savant is special because of brain impairment. Yet not all brain injury leads to savant skills. Some studies have shown that people who have purposeful interruption of the left side of the brain can develop idiot savant skills. However few people wish to participate in such experiments. There are many excellent reasons for not undergoing unnecessary experimentation on one’s brain. The term idiot savant is outdated and inappropriate. Virtually all savants have a high degree of intelligence and are thus not idiots.

1.The first paragraph is presented by ________.

A. stating the background of the text

B. making a definition of “idiot savant”

C. giving examples to lead in the topic

D. making comparison to show our brains work

A. The concept “idiot savant” was first out forward by Dr. Rush.

B. Thomas Fuller who could calculate quickly is poor in art.

C. The idiot savant played by Dustin Hoffman is good at calculation.

D. Tom Cruise has the ability to perform rapid complex calculations.

3.From the last paragraph, we know that ________.

A. brain impairment is a kind of incurable disease

B. the idiot savant may result from the purposeful interruption of the brain

C. experiments on one’s brain are harmful

D. idiot savants are actually very clever in certain fields

4.The text mainly talks about ________.

A. the understanding of idiot savants

B. mental impairment in our work

C. the way that our brains work

D. how to be an idiot savant
