The big box is too heavy for me （ ） A to carry B to carry it C that carry D carrying Only then （ ） that he had lost a chance of achieving his dream A he realized B did he realize C he did realize D when he realized
解题思路： 如下
解题过程：
The big box is too heavy for me （ ）
A to carry B to carry it C that carry D carrying
本题选A。
本题考查“too…to 句型”的用法：
该结构的基本形式为“too+形容词或副词+to+动词原形”，其意为“太…以至于不能…”：
He is too tired to go any further. 他太累了，不能再往前走了。
He is too shy to speak to her. 他太害羞，不敢同她讲话。
It’s too cheap to be good. 这东西太便宜，好不了(即便宜无好货)。
He is too young to know right from wrong. 他太小，还分不清是非。
有时不定式前可以带有一个由介词for引出的逻辑主语：
The box is too heavy for me to carry. 这个箱子太重，我提不起。
另外，该句型有时可与so…that结构转换：
The box is too heavy for me to carry.
→The box is so heavy that I can’t carry it.
注意：
在too…to结构中，当句子的主语和to后面的动词的宾语是同一个时，动词的宾语不能加。
在这个句子中The big box是主语，而carry的宾语也是它，那么就不能再加宾语了。
所以不可以选B。
so...that句型转换的四种方法：
◎当从句的主语与主句中的主语一致，且that从句是否定式时，常用too...to...转换。
The little girl was so tired that she couldn’t walk farther.
=The little girl was too tired to walk farther.
这个小女孩太累了，她不能再走路了。
◎当从句的主语与主句中的主语不一致，且that从句是否定式时，常用too...for sb to do sth转换。
The work is so difficult that we can’t finish it in time.
=The work is too difficult for us to finish in time.
这份工作太难了，我们不能按时完成。
◎当从句的主语与主句中的主语一致，且that从句是肯定式时，常用...enough to do sth转换。
He is so strong that he can lift the heavy box.
=He is strong enough to lift the heavy box.他强壮得足以举起那个重箱子。
◎当从句的主语与主句中的主语不一致，且that从句是肯定式时，常用...enough for sb to do sth转换。
He spoke so clearly that I could hear him.
=He spoke clearly enough for me to hear him.他说得很清楚，我能听明白。
Only then （ ） that he had lost a chance of achieving his dream
A he realized B did he realize C he did realize D when he realized
本题选B。
本题考查的是部分倒装。
句意：直到那时，他才意识到他失去了实现他的梦想的一次机会。
部分倒装是指将谓语的一部分如助动词或情态倒装至主语之前。如果句子的谓语没有助动词或情态动词，则需添加助动词do, does或did，并将其置于主语之前。
only 所修饰的副词、介词短语或状语从句放在句首时，用倒装。
Only in this way, can you learn English well. 只有这样，你才能学好英语。
Only after being asked three times did he come to the meeting. 叫了三次，他才来参加会议。
Only by working hard can we succeed. 只有努力工作我们才能成功。
Only then did I realize that I was wrong. 直到那时，我才意识到我错了。
注意：
当only修饰状语从句时，主句部分倒装，被only修饰的状语从句部分不倒装。
例如：Only when he told me did I realize what trouble he was in.
当only修饰主语时，则不用倒装。
例如：Only Wang Ling knows this.
