Question

and the problem could be settled

____，I think，and the problem could be settled．（　　）

A. To keep up your spirits

B. A bit more effort

C. If you double your effort

D. Making great efforts

Answer 1

答案：B 句中I think是插入语，不影响句子结构；and是并列连词，说明前面是一个简单句，可以排除ACD；a bit more effort是一个省略的祈使句，和后面的部分构成祈使句+陈述句句型，意思是做某事就会怎样．故选B．
