老师们好~我有两道题不懂..—I can't see the blackboad clearly .—perhaps you need ____.A.examine your eyes B.examining your eyes C.having your eyes examined D.to have your eyes examined我觉得他说也许是你的眼睛该被检查检
老师们好~我有两道题不懂..
—I can't see the blackboad clearly .
—perhaps you need ____.
A.examine your eyes B.examining your eyes
C.having your eyes examined D.to have your eyes examined
我觉得他说也许是你的眼睛该被检查检查了,用被动语态.need后用doing或者need to be done 表示,为什么选项是D?
Every minute and every second should be made full ___of___the finails.
A.use ;preparing for B.used ;being prepared for
C.use ;to prepare for D.using ;prepare for
为是么不选A 选C 介词后不是跟动名词

第一个问题：
Perhaps you need to have your eyes examined.或许你需要检查一下你的眼睛.
sth +need+doing\to be done 这时候这个句型表被动,这时need 的主语是物,不是人.
The flowers need waterinig\to be watered.这些花需要浇水了.
在这个句子中Perhaps you need to have your eyes examined.主语是you ,你需要干某事就是主动,所以就是you need to do.
have sth done 汉语是：让（某人）干某事.例如.You should have your hair cut.你该理发了.（也就是你该让理发师给你理发了）
I had my bike repaired yesterday. 昨天我修了下自行车.（也就是我让修车师傅给我修了车）
第二个问题：
Every minute and every second should be made full ___of___the finails.这是个被动语态,它的主动语态是：We should make full use of every minute and every second (to prepare for the finals).这儿是短语make full use of.to do sth. to do sth动词不定式作目的状语,和前面的介词of没有关系,不过改成被动语态后与of靠着了.
满意请采纳,希望对你有帮助.
