重要词句详解】

1. let’s look at the following words and their usage(让我们看看下面的这些词及其用法).

always 一直,总是 usually 通常 often 经常 sometimes 有时候

hardly ever 很少,几乎没有 never 从不。

这些词都是表示频率的副词, 但是在程度上有差别。通常用于一般现在时。如:

i always h**e some milk for my breakfast. 我早餐总是喝牛奶。

he usually gets up at 6:30 in the morning. 他通常早上6:30起床。

he often does homework before dinner time. 他经常晚餐前做作业。

he sometimes goes to movies on friday evening. 他有时周五晚上去看电影。

i hardly /ever eat out at noon. 我很少中午在外就餐。

i never arrive late for school. 我从没有到校晚过。

seldom/rarely

seldom,表示频率,很少,不常,反义词often

rarely,很少地,难得地,少见地

he seldom eats breakfast. 他很少吃早餐。

i rarely eat in restaurants. 我很少在饭馆吃饭。

2. 英语中表次数的用法。

once一次, twice两次, three times三次, four times四次 …

我们可以看出表示次数的词,除了“一次,两次”特殊外,后面的次数都是“基数词+times”构成。

另外同学们还要记住以下词组:

once (twice) a day/ week/ month/ year每天(周/月/年)一(两)次。

3. all, most, some, no 的用法及差异。 all “所有的,全体的”

all students do homework after school.

last night, i cooked all the vegetables in the fridge.

most “大多数的” most students play computer games on weekends.

some “一些” some students go to english movies every day.

no “没有”,注意这里no是形容词。 no students read english novels.

我们可以看出:

all, most, some, no 放在名词的前面做定语,表示数量的多少。

6. how many hours do you sleep every night? 你每天晚上睡几个小时?

这是一个特殊疑问句。“how many +名词”构成了特殊疑问词。

注意:how many 后跟可数名词的复数形式。

how many apples do you h**e?

how many students are there in your class?

如果名词是不可数名词,要用“how much +不可数名词”。

how much milk do you drink each time?

how much water do we need every day?

课文解析3a】

1. pretty表示“十分”作副词用,我们以前学过quite和very也有这种意思。其中它们的程度由浅入深为quite→pretty→very.

he is quite serious.

it sounds pretty good.

nina can sing english songs very well.

2.i exercise every day, usually when i come home from school.

我每天锻炼身体,通常是放学后。

3. eating habits“饮食习惯”。

4. try to do sth意为“尽力去做某事”。

try to get here early.

he tried to pass the exam.

5. ten to eleven times a week.“每周十到十一次”。

注意这种表达。“to”为介词。

翻译:(1)两到三次。 twice to three times.

2)每月四到五次。four to five times a month.

6. of course. “当然”。

7. so you see, i look after my health.“所以你看,我很在意我的健康”。

look after 意为“照顾、照看”。

can you look after my baby when i le**e?

please look after your own bags carefully.

look还可以和许多词搭配,但意思不一样。

(1)look at“看,认真地看”。

please look at the blackboard.

some people are looking at the notice.

(2)look for“寻找”。

old henry looked for his dogs, but he didn’t find it.

i’m looking for my lost pen.

8. good food and exercise help me to study better.好的饮食和锻炼帮助我学得更好。

help sb. to do sth. better帮助某人把某事做得更好。
