此处的port为何意？

--What should I do with this passage?
--____ the main idea of each paragraph.
A. Find out B. To find out

There ____ no water, he had to fetch some.
A. being B. was

第一题题干应该是：I told sally how to get here,I ______, even though he was very busy. 选B。后面有“尽管他很忙”说明因为忙我没有给他写（怎样到那里），这里的B是虚拟语气用法，意思是我“本应该给他写下来（怎样到那里）的。第二题 a great number of许多大量的意思，它和后面的名词作主语看成复数。since1970 since加上过去的点时间 是现在完成时的标志所以选A. 第三题选B.suggest one's doing 的形式。第四题port打错了，应该是pork猪肉的意思。第五题选Find out祈使句表示要求，建议。第六题选A.独立结构，逗号后面已经是完整的句子了，这里面缺状语成分，being合适。如果选B，必须逗号后有and

答案依次是:B;A;
Our English teacher suggested __us to buy__ a good English-Chinese dictionary.

PORT 指"葡萄酒".

A.

B.

第一题？空在哪呢 但估计问题考的要点是B答案
第二题：A很明显的现在完成时，因为since的存在
第三题：B suggest+doing something
第四题port 应该是原产葡萄牙的深红葡萄酒
第五题：A 问题里就是do，所以回答也相应地用do而不是to do
第六题B

I told sally how to get here, even though he was very busy.
A. had to write it out
B. should have written it out
选B,因为句中“I told sally"所以实际上没有"write"那么用虚拟语气。

A great number of universities ___ set up in this country since 1970.
A. have been
