// want, wash, was, what
// American, away, ago, woman
/e/ many, any

2.字母组合al的发音

词汇
1.be on duty 值日
Whos on duty today?今天谁值日?
2.heavy
形容词,重的,其反义词为light轻的,在句中可作表语或定语。
(1)My bag is heavy.我的包很重。
(2)It is a heavy bag.它是一个重的包。
3.full
形容词,满的,其反义词为empty空的,在句中可作表语或定语。
(1)This bottle is full.这个瓶子是满的。
(2)Toms bag is empty. Tom的书包是空的。
4.Carry
搬动、带去,表示用力地提、扛、搬较重的物体等意思,不太强调方向,但有时可以与介词to连用,表示搬到地方。与之意思相近的词take表示把某物或某带到某处去,不强调用多大力气,强调方向性,或有目的地带、拿。
(1)The bag is too heavy. I cant carry it.
这个包太重,我搬不动它。
(2)We often help old people carry water.
我们经常帮助老人提水。
(3)Please carry the book to the classroom.
请把这些书搬到教室去。
5.too
副词,太,有不恰当,不适合之意,在句中修饰形容词或另一副词;它还有另一种意思,即也。句型tooto,表示太以致不能。
(1)She is too young. She cant go to school.
她太小,不能上学。
(2)I cant sing this song, too.
我也不能唱这首歌。
6.have a look, look, see区别
have a look看一看,短语中的look是名词,功能上基本相同于look,强调看这一动作。具体用法上还是有所不同的:have a look是短时间的随意看一看,而look一般是一段时间内倾心专注地看。表示看的词还有see,强调的是看的结果,意思是看见、 看到。Let me see是让我想想的意思。
(1)Let me have a look.
让我看看。
(2)Let me have a look at your picture.
让我看看你的照片。
(3)Please look at the blackboard.
请看黑板。
(4)I cant see it. Its too small.
我看不见那东西,它太小了。
句型
1. Its twelve minutes past eleven.
在该句中minutes 可以省去例如:我们既可以说
Its ten minutes to nine. 也可以说:
Its ten to nine 或Its eight fifty.
2. Today is Tuesday, February 18th.
同学们必须注意该句和汉语的表达顺序不一致,我们在收看资讯联播时,播音员一般总是说:观众朋友们,晚上好。今天是二月十八日,星期二,农历在英文日记中一般也按星期几、日期、天气的顺序,这一点大家要注意。
3. It has no eyes or ears.
它的同义句为It has not any eyes or ears. 或It doesnt have any eyes or ears. 或It has no eyes and no ears.
在这里no=not any.
4. It has three hands-two long ones and a short one.
one 为不定代词,在第一册(上)中已出现过。ones 为它的复数形式。又如:
Thats an empty bottle. Heres a full one.
这里的one就是bottle。再如:
This is your new shirt? Wheres my new one?
这里one指的是上文中的shirt.
5. I want to take some books to the classroom.
want后跟不定式构成短语want to do sth. 我们还学过了 like to do sth.
Take 一般是把物品从说话的地点拿到别的地方。而bring一般是把物品从别处拿到对方说话的地点,故take、bring分别和there、here结合在一起用,例如:
Can you take these clothes there?
Can you bring them here?
6. Its full of books.
be full of是充满的意思,后面跟名词。例如:
The basket is full of eggs.篮子里装满了蛋。
7. So she goes to the policeman for help.
这里for是介词,有寻求,寻找的意思,相当于to ask for或to look for. 例如
The Greens all go out for food = The Greens all go out to look for food.
格林一家都出去找食物了。
语法
形容词的用法
形容词用以修饰名词,表示人或事物的特征。在句中主要用作表语和定语。作表语时,常和be动词或者其他联系动词连用;作定语时,一般放在所修饰的名词前面。
1.This bag is new.(new作表语)
This is a new bag.(new作定语)
2.These bags arent heavy. They are light bags.
这些包不重,它们是轻的包。
