您好,
第一题
1）就是考从属连词that引导的宾语从句中,
如果同时出现多个宾语从句,第一个宾语从句中的that可以省略,其他的that是不可以省略的.
2）colleges that have since become coeducational=
（colleges）, that they have been admitted to those colleges since they become coeducational
括号中的colleges跟后面的宾语从句没关系,不是定于从句,
注意：that引导的是believe的宾语从句
所以就选D
第二题
1）首先 be able to do 能做.是表示经过自身的努力,进而可以做一件事（符合题意）
2）have sth done 是让某事被做,不是由自己做,那传播好的种群特征可以由别人完成吗?
所以就选A
3）第三题
这里应该考的是表达的简洁吧.
1)我们来看D,首先句中的lasting,remain在意思上是重叠的,
2）然后定于从句中的先行词是 an art form,D中后出现了这个词组,那不是重复吗?应该用one
3）E这个答案,即没有意义的重合,也没有结构的重复,表达非常简洁,且语义完成.
希望能帮到您.
