1、Review of units 1-3知识讲解一. 重点词汇1. as as作为连词，引导时间状语从句，“当的时候”，一般用于一般过去时。 例如： As he explored the sea，he took a lot of pictures. 他在探海时，拍了许多照片。 还可以引导原因状语从句，只说明一般的因果关系，语气比because弱，说明比较明显的原因，它引导的从句通常放在句首，有时也放在句尾。 例如： As the car is expensive，we cant buy it. 由于汽车太贵，我们买不起。 As everybody has come，we can set off.
2、 既然大家都到了，我们可以动身了。 assoonas一就 例如： As soon as he arrived in France，he called me. 他一到法国，就给我打电话。 asas表示双方程度相等，“和一样”。 基本句式： A、主语+谓语（系动词）+as+原级形容词+as 例如： Xiao Li is as tall as his brother. 小李和他哥哥一样高。 Your jacket is as new as mine. 你的茄克衫和我的一样新。 B、主语+谓语（行为动词）+as+ 原级副词 +as 例如： He speaks French as fluently as
3、 you. 他说法语和你说得一样流利。 Wang Ying teaches maths as conscientiously as her sister.王莹教数学和她姐姐一样认真。2. a few；few；a little；little few或a few在句中修饰可数名词，后接可数名词复数；也可用来代替复数名词。其中few表示否定，意为“几乎没有”，a few则表示肯定，意为“有一些”。 例如： Few people lived here many years ago许多年前几乎没有人住在这儿。 Look！You made a few mistakes in your homework 看
4、！你在作业中出了几处错。 little或a little在句中修饰或代替不可数名词。其中little表示否定，意为“几乎没有”，a little表示肯定，意为“有一点”。 例如： How much wine did he have last night？ 昨天晚上他喝了多少酒？ Just a little 只喝了一点点。 Hung up，we have little time left 快点，我们没有多少时间了。 a little还常用来修饰形容词、副词、动词，也可以修饰形容词或副词的比较级。 例如： All of them felt a little tiredSo they stopped
5、 to have a rest 他们都感到有点累，所以他们停下来休息。 Lucy runs a little faster than I露茜跑得比我快一点。 3. a little和a bit a bit和a little通常可互换，也可修饰动词、形容词、副词。但在修饰名词时有区别：a little可直接修饰不可数名词；而abit则要与of搭配才能修饰名词。 如： Please open the windowsIts a bit hot请把窗户打开，有点热。 This morning he only had a bit of milk for breakfast今天早上他早餐只喝了一点牛奶。
6、注意： nota little意为“非常、很多、不少”，相当于very或quite等；而nota bit则表示“一点也不”，相当于not at all等。 例如： The boy isnt a bit hungry 那男孩一点也不饿。 The boy isnt a little hungry那男孩非常饿。 4. besides，except，but 这三个词都可以用来表示转折，但是用法有所区别：(1)except与besides 用于肯定句时，except意为“除外(不再有)”；besides意为“除外(还有)”： 例如： We all passed the exam besides Tom.
7、 除了汤姆外，我们也都及格了（汤姆也及格了） 注意：besides在句中的位置较活，可放在句首，亦可放在句中或句末；而except多放在句尾。(2)except前几乎总有all，any，every，no及其复合词等词，而besides前面可用也可不用，依句意而定： 例如： He answered all the questions except the last one. 除最后一个问题没答外，其余问题他都答了。All of them went to Beijing last summer besides Tom. 除了汤姆外，他们去年夏天也都去过北京。(3)except，but，beside
8、s用于否定句时，可以互换。 如： There arent any other people to be considered besides/except/but you. 除你之外，其他人将不予考虑。 I didnt look anywhere besides/except in your bedroom. 除了你的卧室外，我哪儿也没去找。(4)but和except都可以和for连用，构成短语；也可跟 that 从句做宾语。 如： l asked nothing from him but/except that he should write to me every other week 我
9、只要求他每两周给我写一封信。 You cant succeed in the exam but/except that you will work still harder 你若不比以前学习更用功些，是不可能考上的。二. 重点句型1. There be 是“某处有某人或某物”的句型表示“存在”，注意：本句型要用就近一致的原则。 另外，There be句型有一些扩展形式：There + live（lie，stand，come，go）主语其它。 如： (1)Once upon a time，there lived a king. (2)There goes the bell. (3)On the
10、hill（there）stands a house. 注意此句：There will have a class meeting this Thursday afternoon.是错误的。 应将其改为：There will be a class meeting this Thursday afternoon. 对there be句型中的主语提问时，无论主语是单数还是复数都用“Whats + 地点状语？” 如： There are five apples on the plate.Whats on the plate?2. tooto，sothat和enough to do sth. 的句式在一定
11、的情况下可以互换。(1)在肯定句中含so that 的复合句可以转换成含有enough to do sth. 结构的句子。 如： He worked so hard that he finished the work in time. He worked hard enough to finish the work in time. If your son feels well enough to watch TV by then，hell be fine after the game. If your son feels so well that he can watch TV by the
12、n，hell fine after the game.(2)在具有否定意义的句中，三者可以相互转换，但应注意tooto在和enough to do sth. 与sothat转换时，应用句中形容词的反义词或将that从句改为否定句。 如： He is too young to join the army. He is so young that he cant join the army. 或：He isnt old enough to join the army.(3)如果sothat结构中主句和从句的主语不是一致的，应在enough to do sth和tooto结构中的不定式前加上“for
13、 sb.（sth.）”的短语。 如： English is so useful that all of us should learn it well. English is useful enough for us to learn well. The maths problem is so difficult that I cant work it out. The maths problem is too difficult for me to work out. 或: The maths problem isnt easy enough for me to work out.3. li
14、ke后既可接动词-ing形式，也可接动词不定式。含意却有所不同。 如： He likes swimming in Summer.（表示习惯爱好） Its very hot. He would like to（have a）swim. (表示具体的一次行为)：hate等也有类似的用法。三. 综合检测. 看图，根据句意将单词填写完整。 1.

29、rrot 6. kitchen. 单项选择1. 此题考查学生句子中的词语搭配。“举行运动会”为hold a sports meeting，但句中有“there”一词，决定要用there be句型，表示“某时有”，虽然have也有“有”的含义，但它是“(某人/某物)有”故本题答案为A。2. 此题考查学生对助动词、情态动词的理解。will，shall，would都有征求对方意见之意，语气都很委婉、客气，但它们接的人称代词不同。will，would常接第二人称you，shall接第一人称I和we。故此题答案选C。3. 此题考查学生对little/ a little，few / a few的理解。a
30、little/ little修饰不可数名词，a few/ few修饰可数名词。而a little，a few表示“有点，少数几个”，在句中有肯定含义；little/ few表示“少数”，“几乎没有”在句中有否定含义。此题中English是不可数名词，weeks是可数名词，所以答案为A。4. 本题考查疑问词的用法。how long指时间长短，如two days；how often问频率，如three times a day；how much问(不可数)多少；而how far问距离，而本题half an hours bus ride指的是距离，故选C。5. B much, a little, a
31、bit等可以修饰形容词的比较级。6. B同第一题。 7. C看电影要用动词see，worth doing表示值得做。 8. A so表示程度。. 完形填空 1. A从下文“I had to do.”，可看出是拿出练习本。2. C前后有转折关系。3. D use表示运用，符合文意。4. B作者认学数学无用，日常生活用不上数学，因为平时有电脑。5. C吃完早饭就做数学作业，可推断是上午。6. Aat last 表示“最后”的意思。7. B由上文，可知道作者对数学的态度。8. A上午做数学，中饭后，也就是下午，做地理练习。9. C从下文可知答案。10. D around意为“在周围”，take sb. around the world的意思是“带领某人周游世界”。11. B 从作者对地理的态度，可知他的计划认真。12. A it takes sb. time to do sth.是固定句型，意为“花时间干某事”。13. B 从上文可知，妈妈对作者花了整个下午学地理有点担心。14. B the whole=all the，表示“全部的”，“整个的”。15. C but 作介词，后接v-ing分词，和前面not watching连用，意思是“不是而是”。
