初中英语动词不定式用法梳理

八年级英语动词不定式用法梳理动词不定式是由“不定式符号to+动词原形”构成的一种非谓语动词结构。有些动词不定式不带to,动词不定式可以作句子的主语、表语、宾语、定语、补语、状语或单独使用。不定式保留动词的某些特性,可以有自己的宾语、状语等。动词不定式和它后面的宾语、状语等一起构成短语,叫作不定式短语。 一、用作主语 直接把动词不定式置于句首的情况不多,多数情况用it作形式主语,把真正的主语——动词不定式置于句末,特别是不定式短语较长时。动词不定式作主语,谓语动词用第三人称单数形式。带疑问词的不定式短语作主语常置于句首,复合不定式结构作主语常置于句末。如: 1. I t is our duty to try our best to deal with these problems. 2.The head teacher said it was necessary to talk with his mother. 3.How to learn English well is important. 4.To see is to believe.(眼见为实;百闻不如一见) 二、用作表语 动词不定式作表语,常说明主语的内容、性质、特征。如: 1.The best way is to join an English club. 2.The first thing is to listen to the teacher carefully. 三、用作宾语 1.可以接带to的动词不定式作宾语的动词主要有:要求选择同意(ask, choose, agree),期望决定学习(expect, hope, decide, learn),宁可假装知道(prefer, pretend, know),希望想要愿意(wish, want, would like / love)。如: 1)We decided to talk to some students about why they go there. 2)He prefers to eat white bread and rice. 3)Id love to visit Mexico.

初中英语数词

初中英语数词 讲解 数词分为基数词和序数词两种。表示数目或数量多少的词叫基数词;表示数目顺序的词叫序数词。 一、基数词 1.基数词就注意以下几点: (1)几十几的基数词的十位数与个位数之间要用连字符“-”连接。如: eighty-five 85 twenty-six 26 (2)三位数的基数词须在百位和十位(若无十位则和个位)之间用and连接。如:three hundred and sixty-five 365 two hundred and six 206 (3)基数词的复数形式。当基数词hundred,thousand,million,billion等词前有详尽数词或several修饰时,必须用单数。如: several hundred year“s ago几百年前 two thousand students两千个学生 2.基数词的分外用法: (1)表示“几十年代”或“几十岁”时,用逢十的基数词的复数形式。如:in the 1990“s 20世纪90年代 i n one“s twenties在某人20多岁时 (2)用在习语中。如: in twos and threes三三两两地

二、序数词 序数词应注意的几点事项: 1.多位数的基数词变成序数词时,只需将末位基数词变成序数词,前边的基数词不变。 如: forty-two 42 forty-second第42 nine-hundred 900 nine-hundredth第900 2.当序数词用阿拉伯数字表示时,必须在数字后加上序数词的最后两个字母。如:21st第21 32nd第32 3.序数词前大凡要用定冠词the,如果序数词前用a或an时,则表示“又一;再一”(没有详尽范围的限制)。如: Though he had failed twice,he wanted to try a third time. 尽管他已失败了两次,他还想再试一次。 The little monkey had had three apples,and he wanted to eat a fourth one.那只小猴子已经吃了3个苹果,他还想再吃一个。 三、分数和百分数 1.分数 (1)分数的分子用基数词,分母用序数词。如: one fifth五分之一 one tenth十分之一 (2)当分子大于1时,分母用序数词的复数。如:
