Question

sat语法题 1:Robert Koch performed his first significant researc

Answer 1

用isolated更简洁,在SAT中v.>n.

同理,用从句比用两个句子好,因为简洁

3. 首先从语意上来看我们不能判断是哪个变化导致商业变化,所以要有which,接着,accountable 后面要跟介词to 而不是by

4.such--->that

5.will increase--->to increase

6.recline--->decline

7.prided themselves--->prided itself（like只是插入语）

8.to gather---> for gathering（gather这个动作不是technique所发出的）
