2. He transplanted the little tree to the garden ______ it was the best time for it.

A. where B. when C. thatD. until

解析：易誤選A。最佳選項(xiàng)B。when 在此意思是“既然”、“考慮到”， when = since /considering that，實(shí)質(zhì)是表示一種原因。除上面提到的意思外，when 還可表示“當(dāng)……的時(shí)候”、“盡管”、“雖然”。

3. He went home for lunch ______ the clock struck twelve.

A. while B. immediately C. right awayD. at once

解析：易誤選A。最佳選項(xiàng)B。immediately用作連詞，意為“一……就……”，相當(dāng)于 as soon as。

陷阱二 利用相似句型加大迷惑性

常見句型有：It is + 時(shí)間點(diǎn) + when…， It is + 時(shí)間段+ since…， It was /will be + 時(shí)間段+ before…; such...that…， such…as…， so…that…; It is /was + 被強(qiáng)調(diào)部分+ that +其他

2. His plan was such a good one ______ we all agreed to accept it.

A. so B. and C. thatD. as

3. It was after he got what he had desired ______ he realized it was not so important.

A. that B. when C. since D. as

解析：易誤選B。最佳選項(xiàng)A。本題考查強(qiáng)調(diào)句型，正常語序是：He realized it was not so important after he got what he had desired.

陷阱三 利用狀語從句中的時(shí)態(tài)、語態(tài)、語氣、語序、省略等設(shè)置干擾項(xiàng)

1. The old man runs very fast as if he ______ a young man.

A. is B. was C. were D. will be

2. ______ he has limited technical knowledge， the old worker has a lot of experience.

A. Since B. Unless C. AsD. Although

解析：易誤選C。最佳選項(xiàng)D。although引導(dǎo)的讓步狀語從句不倒裝，意為“盡管….”。as引導(dǎo)的讓步狀語從句應(yīng)倒裝，將從句中的表語、狀語或動(dòng)詞原形置于句首。若表語是名詞，前置時(shí)不帶冠詞。如：Child as he is， he knows a lot.

3. This is a very interesting book. I’ll buy it， ______.

A. how much may it cost B. no matter how it may cost

4. ______ your composition carefully， some spelling mistakes can be avoided.

A. Having checked B. CheckC. If you check D. To check

解析：易誤選A。最佳選項(xiàng)C。非謂語動(dòng)詞作狀語時(shí)，其邏輯主語應(yīng)與句子主語一致，此句的 some spelling mistakes 不是 having checked 或 to check 的邏輯主語，排除A和D；若選 B，則兩個(gè)句子之間缺少必要的連詞。

5. —Shall Mary come and play computer games?

—No， ______ she has finished her homework.”

A. when B. since C. unlessD. as soon as

解析：易誤選D。最佳選項(xiàng)C。此句為省略句，答句句首的 No，表明其后省略的是一個(gè)否定句，全句補(bǔ)充完整為：She can’t play computer games unless she has finished her homework.

陷阱四 狀語從句與其他從句、句型結(jié)合起來加大干擾
