7._____cold it is， the young man refused to put on a warm coat.（  ）

A.However

B.No matter

C.As

D.Though

7.A【解析】句意：不管天多冷，这个年轻人都不愿穿上暖和的外套。however引导让步状语从句，其结构为however+形容词+主语+系动词，意为“不管怎样……，无论如何……”，相当于no matter how；no matter“无论，不管”，引导让步状语从句时要与疑问词连用；as/though也可引导让步状语从句，表示“虽然，尽管”，但要用部分倒装结构，即形容词 + as + 主语 + 系动词。故选A。

8.The price of this skirt is _____ that one.（  ）

A.three times much as

B.three times as many as

C.as three times much as

D.three times as much as

8.D【解析】times表倍数的常见形式为“数词+times+as+形容词/副词原级＋as”，故选D。

9.It was not until she had arrived home _____ her appointment with the doctor.（  ）

A.did she remember

B.when she remembered

C.that she remembered

D.had she remembered

9.C【解析】 分析句子结构可知，本句为强调句型：it is/was+被强调成分that/who+其它成分；本题强调的是时间状语从句not until she had arrived home。句意：直到她到家的时候，她才记得与医生的约会。故C正确。
