问题补充：

Tom is little his mother has to help him put on his clothes.

A. enough; to

B. too; to

C. so; that

D. such; that

答案：

A. enough; to

B. too; to

(答案→)C. so; that

D. such; that

解析：句意：汤姆是如此地小以至于他的妈妈不得不帮助他穿衣服。too…to…意为“太……而不能……”，to后面跟动词；be+形容词+enough+to do sth意为“足够……以至于”；so…that…和such…that…都表示“如此……以至于……”；但是so后面跟形容词，而such修饰名词；故选C。
