1)The _____ (天空) is bluer.
(思考:蓝色是blue,在句中加了“r”起什么作用?你能预习相关的内容吗?需要帮助的话,可以在课本P124中找到答案。预习完相关的内容后,2b的表格你一定能先完成了。)
2)The _______(河流) are _______(更清澈)there.
(导学:因be动词是are,所以“河流”用了复数,加了“s”。从第二个空格的词汇,你是否想到了上一题的预习内容?请在1a中继续找出含相应内容的一个词。)
3)Peple can enjy the ______ f _________(自然美).
(导学:“美”在句中是名词,前面学过它的形容词是_________。)

(导学:因be动词是are,所以“马”要用复数,加“s”。)

(导学:句中用了are,所以你所填入的词组要加“ing”构成现在进行时。同时用该词组时要小心,如果是it 和them作宾语时,要将it 和them置abut 的后面,而不是像think ver 一样,放中间。)
10) I’m thinking abut the life _______ _______ ________(在乡村).
二、重要句型:
1)That _____(一定) be fun.
The bk _____(一定) be Tm’s. His name is n it.
(导学:这两句中的情态动词均表示较肯定的“猜测”,若肯定语气不强的话可用may ,否定的猜测用can’t.)
2)The cuntryside is ____ ________ (更安静得多)than the city.
(导学:根据句中than或两个比较项目等可以提示形容词要用比较级,比较级可以被much,a little ,still ,even 等词修饰。)
3) I think the sheep are _____ ________(最好看的) f all.
(导学:根据句中f all 或三个及以上比较项目等可以提示形容词要用最高级,形容词最高级前要有定冠the。)
