C D B D1.sold at twice price,这是倍数词的用法,作状语成分,而as+形容词原形+as 故答案是C(1)倍数+as+adj+n+as (2)倍数+adj(比较级)+than 2.这个题有一定的难度,但把句子成分分析清楚,做起来就简单多了.The way是主语,i told him to try是定语从句,way作try的宾语,由此可见,整个句子就缺谓语,那么答案在C D,但由此句的语境,可以得出答案D3.It was ...that这是很常见的强调句型,即是是一个句子的某个成分提出来,进行强调说明,这个句子的原型应该是:i met Mr.Green in Shanghai ten years ago,把时间状语放到句前,进行了强调,突出时间很久的意思。例:It was he that break the glass.(强调主语he) It was her that i fall in love with(强调宾语) It was by car i go to school everyday(强调状语)4. stadium是露天体育场的意思,那么很显然只能选D了,experienced在这里是“上演”的意思,其他的都不可以
