Modern science has given clear evidence ______ smoking can lead to many diseases.
A. what       B which        C. that     D where

C

解析試題分析:考查同位語(yǔ)從句。本題中的同位語(yǔ)從句that smoking can lead to many diseases解釋名詞evidence的內(nèi)容,that在句中不充當(dāng)任何成分,沒(méi)有任何實(shí)際意義,也不能省略。句意:現(xiàn)代科技已經(jīng)給出了很多的吸煙可以導(dǎo)致疾病的證據(jù)。ABD三項(xiàng)都要在句中充當(dāng)句中成分。故C正確。
考點(diǎn):考查同位語(yǔ)從句
點(diǎn)評(píng):正確判斷句子結(jié)構(gòu)是解題的關(guān)鍵。同位語(yǔ)從句屬于名詞性從句,大多由從屬連詞that引導(dǎo),常常跟在fact, news, idea, thought, question, reply, report, remark, hope, belief等名詞后面。同位語(yǔ)從句一般用來(lái)解釋或說(shuō)明這些名詞的具體含義或內(nèi)容,在邏輯上表現(xiàn)為同位關(guān)系。同位語(yǔ)從句與that引導(dǎo)的定語(yǔ)從句:(1)從先行詞看,同位語(yǔ)從句與名詞之間在邏輯上是“主語(yǔ)+be+表語(yǔ)”的同位關(guān)系。該名詞是需要作特殊說(shuō)明的抽象名詞。例如:They were delighted at the news that their team had won. The news was that their team had won. (2)從引導(dǎo)詞來(lái)看,引導(dǎo)詞that在同位語(yǔ)從句中是連詞,只起連接作用,無(wú)具體詞義,that不可省略;that在定語(yǔ)從句中是關(guān)系代詞,它在從句中充當(dāng)一定成分——主語(yǔ)或賓語(yǔ),有具體詞義,作賓語(yǔ)時(shí)還可以省略。(3)同位語(yǔ)從句的簡(jiǎn)易判斷方法,同位語(yǔ)從句與其先行詞在邏輯上是“主語(yǔ)+be+表語(yǔ)”的同位關(guān)系。所以,可以在名詞和從句之間加系動(dòng)詞be,使之構(gòu)成一個(gè)新句子,如果合乎邏輯,句子通順,則原句為同位語(yǔ)從句;定語(yǔ)從句是不能夠用系表結(jié)構(gòu)把先行詞與從句連接起來(lái)的。

Thirteen vehicles lined up last March to race across the Mojave Desert, seeking a million in prize money. To win, they had to finish the 142-mile race in less than 10 hours. Teams and watchers knew there might be no winner at all, because these vehicles were missing a key part -drivers.

DARPA, the Defense Advanced Research Projects Agency, organized the race as part of a push to develop robotic vehicles for future battlefields. But the Grand Challenge, as it was called, just proved how difficult it is to get a car to speed across an unfamiliar desert without human guidance. One had its brake lock up in the starting area. Another began by throwing itself onto a wall. Another got tied up by bushes near the road after 1.9 miles.

One turned upside down. One took off in entirely the wrong direction and had to be disabled by remote (遠(yuǎn)距離的) control. One went a little more than a mile and rushed into a fence; another managed to go for six miles but stuck on a rock. The “winner,” if there was any, reached 7.8 miles before it ran into a long, narrow hole, and the front wheels caught on fire.

“You get a lot of respect for natural abilities of the living things,” says Reinhold Behringer, who helped design two of the car-size vehicles for a company called Sci-Autonics. “Even ants (螞蟻) can do all these tasks effortlessly . It’s very hard for us to put these abilities into our machines.”

The robotic vehicles, though with necessary modern equipment such as advanced computers and GPS guidance, had trouble figuring out fast enough the blocks ahead that a two-year-old human recognizes immediately, Sure, that very young child, who has just only learned to walk, may not think to wipe apple juice off her face, but she already knows that when there’s a cookie in the kitchen she has to climb up the table, and that when she gets to the cookie it will taste good. She is more advanced, even months old, than any machine humans have designed.

Watchers doubted if any of the vehicles could finish the race because        .

A.they did not have any human guidance

B.the road was not familiar to the drivers

C.the distance was too long for the vehicles

D.the prize money was unattractive to the drivers

DARPA organized the race in order to         .

A.raise money for producing more robotic vehicles

B.push the development of vehicle industry

C.train more people to drive in the desert

D.improve the vehicles for future wars

From the passage we know “robotic vehicles” are a kind of machines that         .

A.can do effortlessly whatever tasks living thing can

B.can take part in a race across 142 miles with a time limit

C.can show off their ability to turn themselves upside down

D.can move from place to place without being driven by human beings

In the race, the greatest distance one robotic vehicle covered was          .

A.a(chǎn)bout eight miles    B.six miles

C.a(chǎn)lmost two miles     D.a(chǎn)bout one mile

In the last paragraph, the writer implies that there is a long way to go         .

A.for a robotic vehicle to finish a 142-mile race without any difficulties

B.for a little child who has just learned to walk to reach the cookie on the table
