这是SC不是CR，我帮你转过来了。 37题：1. can 和perhaps一起用显得累赘，排除CDE。2. to the treatment of 相对 treating显得累赘。排除A。3.这里that后不能把整个句子倒装。 38题：1.很明显这里用so... that...句型，太....以至...。对马可波罗的影响太深，以至于他把...比作Italy。所以选D 39题：1.and连接两个句子必须是独立的，要用标点符号格开。如果 they therefore diagnose也是前面谓语contend的内容那么必须是 and that 而不是用and。所以排除用they therefore diagnose的句子ACD。2.定语从句用分词时一般不用having done，而是用who代替。3.E的句子更容易看懂，因为B里后面 therefore diagnose必须判断究竟是Psychotherapists的谓语还是male psychotherapists 的谓语。而E很明显就可以判断它是male psychotherapist的谓语了，因为单复数不一样。
