拓展提升
1. What are you thinking about？你在考虑什么？A. think about 考虑，思考；与 think of 同义。I can’t tell you now. I’ll have to think about it.
现在我不能告诉你，我要考虑一下。B. think of 意为“想起，想到，认为”时，与think about不同；What do you think of the film
你认为这部电影怎么样？C. think over 意为“仔细考虑，思考”；You’d better think it over and then write down your answers. 你最好仔细考虑一下，然后再写答案。
2. I like it very much because the air is fresher, the sky is bluer and the rivers are clearer there.
我很喜欢它，因为那里的空气更新鲜，天空更蓝，河流更清澈。此句中的 fresher,bluer,clearer是比较级。一般情况下，在单音节词尾加er，以e结尾的只能在词尾加r构成形容词的比较级。在此句中是农村和城市两者之间的比较。
3. I think the countryside is much quieter than the city, too.
我也认为农村比城市安静多了。形容词和副词的比较级前可用much, a little, even, far(much), a lot来修饰，以加强语气。 a little taller 高了一点儿。
4. That must be fun! 一定很有趣！must 意为“一定”，用来表示猜测可能，比may（可能）表示的可能性更大。 但是表示“不可能”时不用mustn’t 或may not，而用can’t。He can’t be in Japan. I saw him just now at school. 他不可能在日本，我刚刚在学校看他了。
5. I think the sheep are the nicest of all.
我认为绵羊是所有动物中最友善的。名词复数特殊的几种：（1）单复数同形的名词有： fish鱼，deer鹿，sheep绵羊， Chinese中国人，Japanese 日本人；（2）不规则变化：child---children 孩子；foot---feet 脚，tooth---teeth牙齿；goose---geese 鹅；mouse---mice老鼠； man---men 男人； woman---women 女人；
注意：与 man 和 woman构成的合成词，其复数形式也是 -men 和-women。如： an Englishman，two Englishmen. 但German（德国人）不是合成词，故复数形式为Germans；（3）只有复数形式的名词： trousers裤子，pants裤子，shorts短裤， glasses眼镜。
6. The pigs must be the fattest and laziest animals on the farm. 在农场上猪一定是最胖最懒的动物。the fattest of ..... 意为“在……中最胖”， fattest是fat的最高级。一般情况下，在单音节形容词词尾加est构成最高级。但fat在变成最高级时要双写t再加est。形容词最高级用于三者或三者以上相比较，其后常用in, of短语表示在某范围内最……。She is the best student in our class. 她是我们班最好的学生。He is the tallest among all the boys. 他是男生中个子最高的。Nanjing Road is one of the the busiest streets in Shanghai.
南京路是上海最繁忙的大街之一。
