1．The mst pwerful earthquake in the past 40 years caused a tsunami that crashed int castlines acrss Asia yesterday，killing mre than 6，500 peple in Indnesia，India，Thailand，Malaysia，and at least fur ther cuntries. 昨天，过去40年来最强烈的地震引发的海啸袭击了亚洲的海岸线，造成印度尼西亚、印度、泰国、马来西亚以及至少四个其他国家6 500多人死亡。
(1)这是一个主从复合句。主句是The mst pwerful earthquake in the past 40 years caused a tsunami；that crashed int castlines acrss Asia yesterday是定语从句，修饰前面的先行词a tsunami，关系代词that在定语从句中作主语；killing mre than…fur ther cuntries是现在分词短语在句中作结果状语。
(2)现在分词短语作结果状语时表示自然而然的结果，它常常位于句末，可以扩展为一个含有并列谓语的简单句。His father died，leaving him a lt f mney(＝and left him a lt f mney). 他的爸爸去世了，留给他很多钱。Their car was caught in a traffic jam，thus causing the delay(＝and thus it caused the delay). 他们的车困在了交通阻塞中，因而耽误了。
现在分词的逻辑主语和句子的主语应保持一致。听到这个消息，他脸红了。(正)Hearing the news，he turned red. (误)Hearing the news，his face turned red. (his face不能发出hearing这个动作)
不定式作结果状语时常表示出乎意料的结果，且其前可加nly表示强调。We hurried t the statin，nly t find that the train had left. 我们匆匆忙忙地赶去车站，结果发现火车已经走了。
单句语法填空①He lifted the rck nly _________(drp) it n his wn feet. ②He cut ff the electricity in time, ____________(prevent) an accident. ③He did his hmewrk carelessly, _________(make) a lt f mistakes. ④They reached the cmpany ut f breath nly ___________(tell) they were fired. ⑤Eurpean ftball is played in mre than 80 cuntries，_________ (make) it the mst ppular sprt.

(1)这是一个主从复合句。主句是Fishermen，turists，htels，hmes，and cars were swept away by huge waves caused by the strng earthquake其中caused by the strng earthquake是过去分词短语作后置定语，修饰前面的名词huge waves，相当于定语从句that/which were caused by the strng earthquake；that reached a magnitude f 9.0是that引导的定语从句，修饰先行词earthquake，关系代词that在定语从句中作主语。
单句语法填空①Yu cannt accept an pinin __________(ffer) t yu unless it is based n facts. ②The by _________(call) Tm is my brther. ③The bk，__________(write) in 1957，tells the struggle f the miners.
句中 when 用作并列连词，意为 “这时(突然)” ，相当于 and then 或 and just at that time。We were discussing the maths prblem when the headmaster came in. 我们正在讨论数学问题，这时校长进来了。
3．I was having breakfast with my three children when water started filling my hme. 我正和我的三个孩子吃早饭，突然海水冲入了我家。
when 作并列连词时，通常不能位于句首；句型中的 be 通常为 was/were；when后句子中谓语动词通常用一般过去时。She was cking when smene kncked at the dr. 她正在做饭，这时有人敲门。
I was abut t start when it began t rain. 我正要动身，这时下雨了。They were n the pint f leaving when the pwer was cut ff. 他们正要离开，这时突然停电了。I had just finished reading the nvel when my father came in. 我刚读完这本小说，这时父亲进来了。
