牛津高英语重点讲(模块 unit 1) Period 1 1. The ship sank but we managed to get on a lifeboat. 【辨析】 manage to do, try to do 两者都有“设法”，“试图”的意思，用法也相似，都接动词不定式。但意思却有区别： manage意思是“设法成功地办好了某事”，即事情有了结果或者会有结果。 try to do的意思是“努力去做某事”，但不一定会成功。而且去做的事情，不一定都是困难的。试比较： He tried to stop a car but he failed．他设法要拦一辆车，但没拦住。 He managed to stop a car and got onto it. 他设法拦了一辆车，并上了车。 【考例】 ① They were surrounded by the enemy, but they____ at last. A. managed to escape B. tried to escape C. tried escaping D. managed escaping 2. Then the ship turned to the left, then the right. turn to 在这里意思是“转向”，又如： Turn to the left and you will find the post office. 向左拐，你会找到邮局的。 【拓展】 turn to 还有“求助、变成”等意思，如： The child turned to its mother for comfort. 那孩子向母亲寻求安慰. The ice turned to water. 冰化成水。 【考例】 ② — Why does she always ask you for help? — There is no one else ________, is there? (2005 北京) A. who to turn to B. she can turn to C. for whom to turn D. for her to turn 3.

After finishing his homework, he went to bed. Having (=When we have) made full preparations, we are ready for an examination. 【考例】 ③ ____ the room, the nurse found the tape-recorder _____. A. Entering; stealing B. Entering; gone C. To have entered; being stolen D. Having entered; to be stolen 4.
