教材导读

1.After our ship crashed against the rocks, I swam as far as I could. 在我们的轮船触礁之后，我尽可能地游。 探究点：against可用作_______词。

[指点迷津] against用作介词，其具体意思如下： (1)相反；反对；违反；违背；逆。

We all should fight against evil.我们都应该同邪恶做斗争。

(2)撞击；撞着，碰着，顶着，触及，与??相撞，同??冲突。．

I pushed against the door and the door opened at last.我用力推门，最后门开了。 (3)逆行，逆??方向，对着；跟??反方向。 Don't drive against the traffic.不要逆向行车。

不要用球撞墙。Don't_______ the ball_______ the wall.

2.By the time I finally felt the land under my feet,1 was tired out. 当我最后觉得土地在我脚下时，我累坏了。 探究点：by the time的意思是“_______”。

by the time通常引导一个时间状语从句，表示“到??的时候”，主句则表示在 此时间之前某个事件已完成。值得注意的是，从句用一般过去时，主句通常用过去完成时； 从句用一般现在时，主句通常用将来完成时。

By the time I got to the station, the train had already gone. 当我到达车站时火车已经开了。

如果主句的谓语是be动词或者是像know等表示认知的持续性动词，则往往用一 般过去时，不用完成时。

By the time he went abroad，he was fourteen.出国那年他14岁。 当我到家时，他们已经离开了。

_______ _______ _______ I got home, they _______already_______. 3. I woke up as the sun was rising?我醒来了，这时太阳正在升起?? 探究点：rise和raise有何区别？

这两个词都有“提高，上升，增加”的意思，但其用法不同。

(1)raise是及物动词，发出此动作的通常是人，可用于被动语态，意为“举起；提高”，如抬头、举手（目、帽、石头、重物等），还可用作比喻，如提高政治觉悟（生活水平、地位、名誉、声音等）。

(2) rise是不及物动词，不能用于被动语态，意为“上升，升起；起身，起立（主语是人）；上涨”以及“（日、月星等）升起到地平线上”。 Please raise your hand if you know the answer. 如果你知道答案就请举手。（请举手，主语是你） The sun rises in the east. 太阳从东方升起。（太阳升起，主语是太阳） ( ) The river_______ recently.

A. rose B. has raised C. has risen D. raised
