初二英语人教版［Unit １１］课堂讲解（二）

8.less than(a week)不到(一周)
He stayed here less than a week.他在那儿呆了不到一星期。
You should finish it in less than a week.你要在一周内完成它。
【提示】less than是“不到(用)……”之意。又如：
It took me less than ten minutes to get there.用不了十分钟我就到那样了。
The woman is less than forty years old.这位妇女不到40岁。
9.more than(two weeks)(两周)多
When will you finish this work?这个工作你什么时候干完?
I’ll finish it in more than two weeks.我将用两完成它。
【提示】more than后亦可变成three(five)weeks三(五)周多，nore than five metres 五米多远，more than two years两年多。
There are more than fifty students in this class.这个班有50多个学生。
10.how often多久，多长
How often do you exercise?你多久锻炼一次?
How often do you write to your friend?你多久给你的朋友写一封信?
【提示】该短语用来提问频率。
11.be late for迟到
Don't be late for school.上学别迟到。
I was late for the meeting for 20 minutes.我开会去晚了20分钟。
12.take a walk散散步
I take a walk every morning.我每天早上散步。
【提示】类似词组还有：take a rest休息一下；take seat坐下，坐一坐；take a bath洗个澡。它们相当于have a walk 散散步，have a rest休息一下，have bath洗个澡。
13.no more than只不过，仅仅
There are no more than ten tickets left.剩不下10张票了。
I have no more than five yuan in my pocket.我的钱包里仅有5元钱。
【提示】no more than与not more的意思不一样，no more than(只不过)，有“少”
的意思。not more than(不多于)没有“多”或“少”的意思，只是客观说明数目。如：
I have not more than five yuan in my pocket.我口袋里最多有5元钱。
14.be late for,be late to,be late(in)的区别
Hurry up.or we'll be late for the train.快点，不然就赶不上火车了。
【提示】be late for后接名词，往往强调主语(某人)晚了，迟了。be late to是“迟迟去，很晚去”，后接名词时，to是介词。后接动词时，to是不定式。be late(in)表示“(做某事)晚了”，往往强调本身晚了，in后接动名词。in常省去。如：
It's not too late to go now.现在走还不晚。
Sorry,I was late(in)getting up this morning.对不起，今天早晨我起晚了。
