35、an enjoy them at the teahouse,从句是 you like the Beijing opera, traditional music or magic shows。精选学习资料 - - - - - - - - - 名师归纳总结 - - - - - - -第 11 页,共 17 页12 思考:如何使用 if条件状语从句呢? 在句中做条件状语的从句是条件状语从句,可以放在句首, 也可以放在句末。常见的 if条件状语从句表示在某条件下, 某事很可能发生。 紧跟在 if 后面的句子是从句。e.g.If you ask him,he will help you如果你请他帮忙,他
36、会帮你的。If you fail in the exam,you will let him down如果你考试不及格,你会让他失望的。 另外,if从句还表示不可实现的条件或根本不可能存在的条件,也就是一种虚拟的条件或假设。 从句多用一般过去时或过去完成时,表示对现在或过去的一种假设。e.g.If I were you,I would invite him to the party如果我是你,我会邀请他参加聚会。学习小窍门:if 条件句不一般,几个要点记心间;条件句,放在前,逗号要放句中间。条件句表可能,主句多用将来时;条件句表事实,主句常用现在时。 if:当“是否”讲时,引导宾语从句。e.g.
37、I dont know if he will be free tomorrow. 我不知道他明天是否有空。注意: if引导的条件状语从句中,如果主句使用的是一般将来时,或含有情态动词的句子或祈使句,从句通常用一般现在时。e.g.If it rains tomorrow, we will not go to the zoo. 如果明天下雨的话,我们将不去动物园。If he comes, let me know. 如果他来,让我知道。(从句用一般现在时,主句是祈使句)难点知识讲解:动词不定式(I )(1)动词不定式的含义生活中我们常遇到“我努力去理解”、“决定留下来”等表达方式,其中连续出现了两个
38、动词,这种情况下英语应该如何表达呢?首先请看下面的例句:We decided to stay for a cup of tea. 我们决定留下来喝杯茶。精选学习资料 - - - - - - - - - 名师归纳总结 - - - - - - -第 12 页,共 17 页13 I tried to understand the words. 我努力理解这些话。I want to go to the teahouse. 我想去茶馆。这三个句子中使用了decide to do sth. ,want to do sth. ,try to do sth.的表达方式,即行为动词后的动词都采用了“to+动词原
39、形”的结构。我们把这种结构称为动词不定式。其否定形式是“not to do”。(2)动词不定式作宾语的用法动词不定式置于谓语动词之后,作动词的宾语, 表明意图、 希望或决定的内容。在英语中,并不是所有两个动词连用时都采用“动词+不定式”的形式,一般说来,用不定式时, 所表示的多为将来的行为。 但是在具体使用中同学们还要注意记忆,因为动词不同,其后动词形式的要求也就不同。常见的后面接“ to 十动词原形”作宾语的动词有:plan, decide, hope, want, agree, offer, try, like, love等。口诀(接不定式作宾语的动词)想要学习早打算( want lear
40、n plan)快准备 有希望( prepare hope wish expect)同意否 供选择( agree offer choose)决定了 已答应( decide determine promise)尽力去 着手做( manage undertake )别拒绝 别假装( refuse pretend)失败不是属于你( fail)e.g.Tom refused to lend me his pen. 汤姆拒绝把他的钢笔借给我。We hope to get there before dark. 我们希望在天黑之前到达那儿。The girl decided to do it herself.

42、例子一些以“辅音字母 +y”结尾的形容词,要把 y 改为 i 再加-ly 。happyhappily, angryangrily 有些以 -ble 或-le结尾的形容词,去掉e 加-y 。possible possibly terribleterribly 少数以 e 结尾的形容词,要去掉e 再加-ly 。但绝大多数以 e 结尾的形容词仍然直接加-ly 。true truly politepolitely widewidely 以-l 结尾的形容词变为副词时仍然要在词尾加 -ly , 而不是只加 -y 。 除非是以 -ll结尾的才在词尾只加 -y 。careful carefully usef
43、ul usefully fullfully 温馨提示:副词修饰行为动词这一点。如:He is very _(careful). He does everything _(carefully) 第一句中是作表语,用形容词careful ;第二句中修饰行为动词does 用副词carefully。常考的形容词和副词辨析有:hard 努力 hardly 几乎不; late 迟的,晚的lately 近来;deep 深 deeply 深深地; near 靠近 nearly 差不多;wide 宽 widely 广泛地;high 高的 highly 高度地; close 靠近的closely 密切地; fre
44、e免费的 freely 自由地。典例剖析:Tom studies _ but his sister _ studies. Ahard,hard Bhardly ,hardly Chard,hardly Dhardly ,hard 答案: C 解题技巧:此题第一个陷阱是hard 和 hardly的区别,通常我们会认为hard 的副词是hardly ,事实上 hard 既是 adj. 又是 adv. ,而 hardly 是另外一个 adv. ,中文是“几乎不”。 hard 作为 adv. 时,通常在修饰的动词之后,而hardly 通常在动词之前,译这句中文“ Tom学习努力,而他的妹妹则几乎不学习
