Everyone in our class was working hard and doing what we could _______ a good
college.A.enterB.to enter C.enteringD.entered,求分析句子成分,and doing

选B.
不定式做目的状语.努力学习的目的是上好大学.
and是并列连词,working 和doing由and连接,表示并列的成分.
doing what they could （do）的what引导宾语从句,做do的宾语
再问： working 和doing连接表示什么意思？doing what they could （do）这里面doing是跟what连在一起的？怎么知道could后面有没有省略的 do呢？could是可以的意思吧，在这里意思不通吧
再答：首先，and是并列连词，【连接的句子成分和时态必须一致】。这里都是现在进行时态。要不怎么叫并列连词呢？第二个问题could是情态动词，不能单独做谓语，所以肯定是省略了实意动词啊。比如： I could read a book。就不能把read去掉。
再问： could 这里不是省略了do 吗？或者说直接加enter的原型也行啊，这个怎么分辨啊？working hard and doing这什么意思啊？我说翻译过来汉语，工作努力，？
再答： doing what they could （do）的what引导宾语从句，做do的宾语这是what的宾语从句啊。 do 【what you could 】to do sth 是做你能做的以达到...目标。实际上是do 【sth】 to do sth 只不过这里的sth改成了宾语从句而已
再问： what引导的从句，然后不能和主句do一样，然后就省略吗？一个句子不能同时出现两个do吗？
再答：英语中为了简洁，通常会尽量避免同时出现两个一样的谓语动词。你可以说： I can do what I can do。但为了简洁，同时can的实意动词也是do，与主句谓语动词do一样，是可以省略的！
