這個(gè)情態(tài)動(dòng)詞后該接什么

請(qǐng)看題，這個(gè)情態(tài)動(dòng)詞后該接什么？

That day Mr Smith got up late, so he ran as fast as he could _________ the early bus.

A. catch                        B. to catch                  C. catching                    D. caught

【分析】此題容易誤選A，認(rèn)為情態(tài)動(dòng)詞后只能接動(dòng)詞原形。但是，錯(cuò)了，正確的答案是B。其實(shí)情態(tài)動(dòng)詞 could 后本來(lái)有動(dòng)詞原形 run，只是被省略了，即此句的完整形式應(yīng)是 …so he ran as fast as he could run to catch the early bus，其中的不定式 to catch the early bus 為目的狀語(yǔ)。又如：

(1) My parents did what they could _________ my aunt and uncle.

A. help                        B. to help                       C. helping                        D. helped

(2) He read what he could _________ his knowledge.

A. widen                     B. to widen                     C. widening                     D. widened

以上兩題均選B，即選不定式，且此不定式為目的狀語(yǔ)。但是，同學(xué)們?nèi)魮?jù)此形成思維定勢(shì)，也會(huì)麻煩。為此，請(qǐng)?jiān)倏磧深}：

(1) He ran as fast as he could _________to catch the bus.

A. hope                       B. to hope                       C. hoping                        D. hoped

【分析】此題的最佳答案不是B，而是C，其中的現(xiàn)在分詞短語(yǔ) hoping to catch the bus 用作伴隨狀語(yǔ)，即一邊跑一邊在希望能趕上早班車(chē)。

(2) He spent every minute he could _________ foreign languages.

A. study                      B. to study                      C. studying                     D. studied

【分析】此題也應(yīng)選C，但是，它與上題選現(xiàn)在分詞 hoping 表伴隨有所不同，此題的 studying 其實(shí)與其前的動(dòng)詞 spend 有關(guān)，即此句中的 studying 為動(dòng)名詞，其前省略了介詞 in。注意spend 的句型：spend + 時(shí)間或金錢(qián) + (in) doing sth(from m.52ysedu.com)。
