參考答案及解析：

1.C 自從Johny離開(kāi)學(xué)校有四年時(shí)間了。

2.C　將來(lái)完成時(shí)態(tài)。Leave for 離開(kāi)一個(gè)地方到另一個(gè)地方去，By the time　信號(hào)詞。

3.B　一般將來(lái)時(shí)態(tài)。 will 表示一種主觀意愿。

4.D　將來(lái)完成時(shí)態(tài)。by the end of　到……時(shí)間為止，在此句中引導(dǎo)的時(shí)間狀語(yǔ)從句為將來(lái)時(shí)間，所以是用將來(lái)時(shí)。答案B，D選取哪個(gè)?機(jī)器(machines)是被修的，所以用被動(dòng)語(yǔ)態(tài)。顯然，D為正確答案。

5.D 他們相信通過(guò)使用計(jì)算機(jī)，工廠的生產(chǎn)效率將會(huì)大大地提高。這是一個(gè)表示將來(lái)的被動(dòng)語(yǔ)態(tài)，主句中believed為謂語(yǔ)動(dòng)詞，是過(guò)去式，故從句中的將來(lái)時(shí)態(tài)為過(guò)去將來(lái)時(shí)，答案范圍縮為B，D。另外，工廠的生產(chǎn)(the production of their factory)是被提高的，所以為被動(dòng)語(yǔ)態(tài)。由此，答案為D。

6.B “no sooner……than……”固定短語(yǔ)結(jié)構(gòu)，意為 “ 一……就……”，?？純?nèi)容。

7.A unless除非，information信息，我們什么都不能做除非被給予更多的信息，這句為一般現(xiàn)在時(shí)的被動(dòng)語(yǔ)態(tài)。

8.B 被動(dòng)語(yǔ)態(tài)的否定形式。environmental problems環(huán)境問(wèn)題。

9.C is going to表示將來(lái)要怎么樣，相當(dāng)于will，其后面的動(dòng)詞同樣用原形. 足球賽將在下午舉行，足球賽是被舉行的，所以用被動(dòng)形式be held.

10.D take down記下;in case以防;witness目及者，見(jiàn)證人;address，住址。我將記下你的名字和住址，以備你作為一個(gè)見(jiàn)證人時(shí)用。一般現(xiàn)在時(shí)的被動(dòng)語(yǔ)態(tài)。顯示然答案為D。
