11.   The rise in the price of crabmeat and an increase in demand has convinced some Floridians they should try to harvest and sell a species of large crab that lives deep in the waters of the Gulf of Mexico.

(A) has convinced some Floridians they should try to harvest and sell a species of large crab

(B) has convinced some Floridians to try harvesting and selling a large crab species

(C) has convinced some Floridians that they should try the harvest and sale of a large crab species

(D) have convinced some Floridians to try to harvest and sell a species of large crab（D）

(E) have convinced some Floridians to try and harvest and sell a large crab species

偶查了WEBSTER's 字典,看到两个这样的用法:

convinced himself that she was all right?William Faulkner*  A convinces A self that ...

*something I could never convince him to read?John Lahr   A convince B to do sth

是不是可以解释这题为虾米选D了?大侠们还有更详细的解释么?

这个啊....

A,B,C用has，肯定错；

E将原意try to harvest改成try and harvest错。

另外还有小毛病一大堆：A类似于convince这样的祁使动词后面的从句用虚拟但是要省略should；B里面a large crab species好像是a large species一样rather than "species of large crab".... 等等等等

(D) have convinced some Floridians to try to harvest and sell a species of large crab（D）

(E) have convinced some Floridians to try and harvest and sell a large crab species

补充一下，还有一个错误是large crab 是后面主语从句的主语，而不是large crab species

两位大侠真是仔细啊!谢谢!

1)sell a large crab species -----unidiomatic

2)A,B,C用has，肯定错；

3)TRY TO DO和TRY AND DO有细微区别

重心不同.
