提能力——微写作
根据汉语提示并运用以上语法用英语写一段话
最近我一直在读一本吴承恩写的小说。这本名叫《西游记》(Jurney t the West)的书非常有趣。别人都喜欢勇敢聪明的孙悟空，而我却喜欢懒惰可爱的猪八戒。
Recently I have been reading a nvel that/which was written by Wu Cheng’en.The bk whse name is Jurney t the West is very interesting.Others like Sun Wukng，wh is brave and clever.Hwever，I like Zhu Bajie wh is lazy but lvely.•be affected by受……的影响；被……感动
be affected with感染……疾病
•effect n．作用；影响
have an effect/influence n/upn对……产生影响
•affectin n．喜爱
•be a shck t...对……而言是一件震惊的事
in shck吃惊地，震惊地
•shcked adj.感到震惊的
be shcked at sth./that...对……感到震惊
be shcked t d sth.因做某事而感到震惊
•shcking adj.令人震惊的
bury 把某物埋在……

•survivr n．幸存者

•suffer frm遭受……折磨；患……病
•suffering n.受苦，遭难；苦楚，苦难
•sufferer n.受害者；患者
•be struck with/by被……所袭击(感动)
It strikes 某人觉得……；某人突然想起……
sth.strike sb.(＝sb.strike n sth.)某人想到……
•be n strike在罢工
g n strike举行罢工
•表示“突然想到”的单词还有hit，ccur。
ruin n.废墟；毁灭 vt.毁灭；使破产
be/lie in ruins成为废墟；毁灭
fall/cme int ruin成为废墟；毁灭
ruin ne’s hpe/health毁掉某人的希望/健康
•as if相当于as thugh，意为“似乎，好像”，用在seem，lk等系动词之后引导表语从句。
•as if/thugh还可引导方式状语从句。若as if从句描述非现实情况，则用虚拟语气。
①当从句表示与现在事实相反的情况时，谓语动词用一般过去时(be动词一般用were)；
②当从句表示与过去事实相反的情况时，谓语动词用过去完成时(had＋过去分词)；
注意：若从句描述的情况发生的可能性很大，则不用虚拟语气。
•本句中killing mre than 6,500 peple...为现在分词短语作结果状语。
•现在分词(短语)作结果状语常表示意料、情理之中的结果，而不定式(短语)作结果状语常表示出乎意料的结果。
•结果状语表示的动作一定发生在谓语动词之后，所以一定不能使用having dne，因为having dne一定发生在谓语动词之前。
技巧一点通
•定语从句是指一个句子作定语，修饰一个名词，该名词叫先行词。引导定语从句的that，which，wh，when，where等叫关系词。其中that，which，wh，whm常常在从句中作主语或者宾语。而whse常常在定语从句中作定语。
•在写作中，如果涉及两个简单句，而一个简单句的主语或者宾语恰好在另一个句子中出现过，就可以把两个句子合并成一个定语从句。
