9大语法难点(1)一、宾语从句1.宾语从句的含义充当主句宾语的从句叫做宾语从句。
如:She knew that the teacher had se en the film.她知道这位老师看过这部电影。
“that the teacher had seen the film”做 knew 的宾语,同时又是由连接词 that 引导的从句,所以它叫做宾语从句。
2. 宾语从句的分类(1)动词宾语从句:顾名思义,它是位于动词后面的宾语从句。
如:He asked whose handwriting was the best in our class.他问我们班上谁的书法最好。
(2)介词宾语从句:顾名思义,它是位于介词后面的宾语从句。
如:I agree with what you said just now.我同意你刚才说的话。
(3)形容词宾语从句:顾名思义,它是位于形容词后面的宾语从句。
如:I am afraid that I will be late. 恐怕我要迟到了。
3. 引导宾语从句的连接词(1)that:没有含义,在宾语从句中不做成分(2)whether/if:表示是否,在宾语从句中不做成分。
I don't know if /whether he still lives h ere after so many years. 我不知道这么多年后,他是否还住在这里。
(3)连接代词:what, which, who, whom, whose(在宾语从句中做主、宾、表和定语)连接副词:where, when, how, why(在宾语从句中做状语)The small children don't know what is in their stockings.(what 在宾语从句中做主语)这些小孩子不知道什么在他们的长筒袜里。
Could you tell me why you were late for the meeting this morning?(why 在宾语从句中做原因状语)你能告诉我为什么你今天早上开会迟到吗?4. 在做宾语从句的题目时应注意两点(1)时态:①当主句是现在时态时,宾语从句可以根据需要使用任何时态。

5.美国内战爆发的根本原因、导火线、开始的标志分别是什么?
6.简单评价林肯。
7.日本明治维新的内容有哪些?
8.日本明治维新的性质和影响分别是什么?
参考答案:
1.玻利瓦尔和圣马丁。
南美的“解放者”。
2.封建王公。
英军进攻章西城,年轻的章西女王领导军民与英军展开激战;章西失陷后,她率军转战外地,战斗中,她身先士卒,直到壮烈牺牲。
3.(1)通过改革,俄国的经济、军事实力大大增强,一跃成为欧洲军事强国,为对外扩张准备了条件。
(2)彼得一世改革以强兵和学习西方技术为目标,开启了俄国近代化的进程。
(3)在彼得一世的统治下,农奴制进一步强化,后来成为俄国社会发展的障碍。
4.性质:自上而下的资产阶级性质的改革。
积极影响:是俄国历史上的一个重要转折点,改革废除了农奴制,促使社会的各个方面出现了新的气象,推动俄国走上了发展资本主义的道路。
5.根本原因:南方种植园经济与北方资本主义经济在奴隶制存废问题上的矛盾无法调和。
导火线:1860年11月,共和党候选人林肯当选为美国第16任总统。
开始的标志:1861年4月,南方军队挑起战争。
6.林肯为维护国家统一和解放黑人奴隶作出了杰出贡献,得到了美国人民衷心的爱戴,成为美国历史上的著名总统。
7.政治上,废藩置县,实现中央集权。
军事上,实行征兵制,建立新式军队。
经济上,推行地税改革,以“殖产兴业”为口号,大力发展近代经济。
社会生活上,提倡“文明开化”,向西方学习,改造日本的教育、文化和生活方式。
8.性质:自上而下的资产阶级性质的改革。
影响:明治维新成为日本历史的重大转折点,通过明治维新,日本迅速走上了发展资本主义的道路,实现了“富国强兵”,开始跻身资本主义强国之列;但明治维新保留了大量旧制度的残余,军国主义色彩浓厚,日本强大起来后,很快走上了对外侵略扩张的道路。
