【提示】 today作后置定语修饰air , air前要加定冠词the.
【扩展】The air today is nice and clean.意思是:今天的空气非常／很清新。英语nice and和good and同样是一个习惯用语，用在形容词之前加强语气,其含义是very (很、非常),实际上就是一个偏正结构,nice and对后面的形容词起了修饰作用。
例如： I was good and hungry.我当时很饿。
【答案】D
4.We often_______(clean )our classroom after school.
【提示】一般现在时表示经常性、反复性和习惯性的现时行为。当句子主语为除第三人称单数外的其他人称时（一、二人称单数及复数各人称），一般现在时的构成为动词原形。由于一般现在时所表现的是现时行为的三性（经常性、反复性和习惯性），所以常用的时间状语有：often，sometimes， every，usually，always， normally等。
【答案】clean
5.Who_______(watch)TV every day? Do you know?
【提示】首先看时间状语，判定是一般现在时。然后，判定用watch还是watches,在不知道是谁的情况下，一律用单数。
【答案】watches
6.What time do the students have lunch?(用Tom改句子)
【提示】完成本题关键在于要明确一般现在时的构成：
①主语+谓语+宾语+状语；
②当主语是一、二人称或复数人称时，谓语动词不变；
③当主语是单数第三人称时，谓语动词要变化（+s或es），如变此句为一般疑问句用does，然后谓语动词恢复原形。
【答案】What time does Tom have lunch?
7.“_______do they get there?”“By air.”
A、What B. Where C. How D. Which
【提示】By air意思是by plane，译作乘飞机。对by air进行提问,在四个选项中只有C是对的。
【答案】C
【妙文赏析】
I Get an A in Maths
Mr Brown was born in a poor family .He couldn\'t go to school when he was young. Now he\'s a porter (搬运工)and works at a station. He doesn\'t think it\'s necessary (必要的)to know some knowledge(知识)of science .His son, Bill, began to go to school last year. The boy likes nothing except playing. He doesn\'t listen to the teachers in class and can\'t do his homework after class. It\'s the hardest thing for him do maths exercises .And he wents to drop it .

“I can\'t do my maths homework,”said the women.“Maybe your father can help you.”
Then she asked her husband to help their son with his maths. Mr Brow said,“but I don\'t know maths, either.”
“It doesn\'t matter,” said his wife .“You\'ll only coax him out of crying .”
Mr Brow had to do as his wife said. The next afternoon Bill came back and showed his exercise-book to his father. The man had a look at it and shouted to his wife,“ come here quickly ,dear ! I got an A in maths!”
【思路点拨】
1.第一句就告诉读者，Mr Brown was born in a poor family ,接下来讲，He couldn\'t go to school .就是说Mr Brown未能上学是因为他家境贫寒。
2、在文章中指出：The boy likes nothing except playing,这就是他无法完成作业的最主要原因。
3、Their son, Bill ,began to go to school last year.从这句话可以看出Bill还不到十岁，像这么大的孩子，哭泣大都是为了一些小事。
