Unit 7考點透視 考例回顧

1. AIDS is a disease that breaks down the body’s immune system and.... (Reading)

【考點】 break down可作及物動詞,作“破壞;使失效”解。也可作不及物動詞,常表示“(計劃,談判等) 受挫折、失敗”或“感情失去控制”或“(機器)停止運轉”。

【考例】 News reports say peace talks between the two countries______ with no agreement reached.(NMET 2003)

A. have broken down

B. have broken out

C. have broken in

D. have broken up

【解析】由with no agreement reached (沒達成任何協議)這一提示可知,全句要表達“和談失敗”之意。而break up“驅散,分開”;break in “插嘴”;break out“爆發”,都不符合句意,可排除。break down意為“(談判等)失敗”,符合句意,故選A。

2. She spends much of her time telling others about her disease and encouraging people to learn how to protect themselves. (Reading)

【考點】 及物動詞encourage的意思是“鼓勵”,表示“鼓勵某人做某事”用encourage sb. to do sth.。

【考例】 My advisor encouraged ______ a summer course to improve my writing skills. (北京2004)

A. for me taking B. me taking

C. for me to take D. me to take

【解析】 根據短語encourage sb. to do sth.可知應選D。

3. I had been feeling sick for a long time and my mum had taken me to hospital to have me examined. (Integrating skills)

【考點】 過去完成進行時的構成是“had+ been+ doing”,表示從過去某時間開始到過去另一時間為止,該動作一直在持續進行着,它具有過去完成時和過去進行時二者的特徵。

【考例】 The crazy fans ______ patiently for two hours’ and they would wait till the movie star arrived.(重慶2004)

A. were waiting

B. had been waiting

C. had waited

D. would wait

【解析】從and後的分句可知電影明星還沒有到,所以當時還在“等”,體現了進行時態;從第一分句的時間狀語for two hours可知是過去完成時,由此可知用過去完成進行時,故選B。

虛擬語氣的幾種常見句式

1. wish後的賓語從句

表示現在不能實現的願望,從句的謂語用過去式;表示過去未能實現的願望,從句的謂語用had + 過去分詞;表示將來不太可能實現的願望,從句的謂語用would + 動詞原形。如:

我真希望知道這個問題的答案。

(事實上不知道)

(你去的可能性不大)

2. as if 或as though引導的表語從句和狀語從句

表示與現在事實相反,從句的謂語用過去式;表示與過去事實相反,用had +過去分詞;表示與將來事實可能相反,用would + 動詞原形。如:

She looks as if she were sick.

He looks as if nothing had happened to him.

他看上去好像什麼事都沒發生似的。

(事實是出問題了)

(場上情況表明有可能)

3. if only後的句子

If only I could learn English well in one day.

要是能在一天內把英語學好就好了。

(事實上做不到)

If only I had not been late for the interview.

要是我面試沒遲到就好了。(事實上遲了)

(事實上不會回信)

4. would rather後的從句

你早該睡覺了。

6. advise， suggest， order， require， command， demand， desire， propose， insist， request等後的賓語從句常用虛擬語氣,從句謂語動詞用should+動詞原形,should常被省略。
