II. Grammar and Vocabulary
Section A: Multiple choices
Directions: Beneath each of the following sentences, there are four choices marked A, B, C and D. Choose the one answer that best completes the sentence.
1. Self-driving is an area ________ China and the rest of the world are on the same starting line.
A. that B. where C. which D. when
【答案】B
【解析】
【詳解】考查定語從句。句意:自動駕駛是一個中國和世界其它國家都在同一起跑線的領(lǐng)域。此處是限定性定語從句,先行詞為area,關(guān)系詞在從句中作地點狀語,應(yīng)用關(guān)系副詞where,相當于in which。故選B。
2. There’s been much finger-pointing and debate over who ________ for the extreme weather conditions.
A. blames B. has to blame C. is to be blamed D. is to blame
【答案】D
【解析】
【詳解】考查固定搭配。句意:對于誰應(yīng)該為極端天氣狀況負責(zé),人們有很多的指責(zé)和爭論。根據(jù)句意可知,此處表示“某人應(yīng)受責(zé)備”,應(yīng)用固定搭配be to blame,表主動表示被動,故選D。
3. Our ancestors had no iron tools and wheeled vehicles,yet they managed to move stones that ________ more than a hundred tons to the site.
A. weighed B. were weighed C. were weighing D. weigh
【答案】A
【解析】
【詳解】考查時態(tài)。句意:我們的祖先沒有鐵制工具和輪式車輛,但他們設(shè)法將重達100多噸的石頭運到了現(xiàn)場。分析句子可知,句子為“that”引導(dǎo)的限制性定語從句,“that”代指先行詞“stones”,在從句中作主語,根據(jù)句意和句中“managed”可知,句中陳述的是過去發(fā)生的事,應(yīng)用一般過去時,“weigh”意為“有……重”,“stones”和“weigh”為主動關(guān)系,“weigh”的過去式為“weighed”,故空格處應(yīng)填“weighed”。故選A項。
