题目内容

3．---Why won't you go to the movie with me，Gina？
---Because I              it twice．（　　）
A．seeB．have seenC．sawD．will see

分析 翻译：--Gina，你为什么不和我一起去看电影？
--因为我已经看过两次了．

解答 答案：B．若某一动作到现在为止已经发生了若干次，则要使用现在完成时，根据句中的twice可知符合现在完成时，现在完成时结构have/has+动词的过去分词，故选B．

点评 本题考查现在完成时的应用．现在完成时有以下用法：现在完成时的含义之一是过去完成的动作对现在仍有影响，用以下四大标志词可以表达这种含义：以already，just和yet为标志以ever和never为标志以动作发生的次数为标志以so far为标志；过去开始的动作可以延续到某一点结束，也可能继续延续，这时就要根据时间"点"、"段"选择相应的介词for或since．

Follow Your Dream
When Jack was a child，he had a dream to be an astronaut （宇航员）．He studied hard and took a lot of tests，but he was never chosen．Time went by．Jack got older and older，and he couldn't take any tests．However，he went on training and studying hard．He would never give up．
One day，he heard that some doctors were doing some very important medical experiments．For those experiments they needed a very old astronaut．Jack was the only old man in the whole world who was trained to fly in a spaceship （飞船）．He got the chance this time．
The experiments were successful．They helped doctors find a new way to cure （治愈） one of the worst illnesses for old people，and Jack became a hero．
So even if our plans don't work in the way we hope，we should keep on working hard．Because of our hard work，maybe even better things will happen．
