it是指代 前面的her baby.因为小孩较小可不太区分性别所以有此用法.
注意第5点
简简单单一个代词IT真是神通广大,用途多多,其功力比其他任何代词都庞大.
从中文立场看,好些无主语的句子,在译成英文时,都非请IT协助不可.例如：
①是这样!（That's it!）
②没办法.（It can't be helped.）
③轮到我了.（It is my turn.）
④事实上,我们可以打败他们.（As it is,we can beat them.）
⑤离开这里不远.（It is not far from here.）
⑥只要一块钱.（It is only one dollar.）
⑦这儿真热.（It is so hot here!）
此外,“it”还有下列五种用法：
⒈代替上文提到的事物或情况,如：
Look up the word in the dictionary if it is difficult to you.
I would appreciate it if you could do me a favour.
⒉代替没生命的东西,如：
Here is a plastic box.It is useful.
Don't throw the old newspaper away; you may need it.
⒊代替普通动物,如：
The dog outside belongs to the owner of the house.It is very fierce.
Look at the cat!Isn't it furry?
指大动物,如马、大象等或指人们心爱的宠物,如猫、狗等时,可用“he”或“she”,而不用“it”；故事中的动物便是个例子,如：
When the children saw a horse coming,they stopped and looked at him.
A cow is grazing grass in the field.She looks very strong.
⒋用来指天气、日期、季节、时刻、距离等,如：
It is raining outside.Don't go out!
It is the 20th of December.
Time flies!It is vacation again.
It was half past five when Jason got up.
It is very far from the school to the market.
It is only a short distance to the library.
⒌可以指性别不详的婴儿,及已知的事实,如：
The baby next door kept me awake.It cried loudly.
Yes,I was at home last night.What about it?
When the company closes down,it (i.e.this event) will affect some staff's future.
⒍可以用来强调句子的某部分,如：
I respect David.It is he that has made the department what it is now.（强调主语）
It is Mandarin that Janet has failed to pick up.(强调宾语)
It is only recently that she has embarked on the learning of Mandarin.（强调副词“recently”）
从上述例子看,代词IT的功用,不仅在代替单数的事物和动物等,还可以协助强调句子成分以及在中英翻译中协助中文无主句的英译.

D
表示五分之三的意思~~

1,the third three
2,C

（u）nder /ʌ/
l(igh)t /ai/
b(e)d /e/
(o)nly /əu/
n(a)me /ei/
thr(ee) /i:/
c(a)n /æ/
s(o) /əu/
t(oo) /u:/
g(o) /əu/
cl(o)ck /כ/
m(i)nus /ai/

the same...as...什么 同什么一样.前后的东西要一致.
例如：he has a coat the same as my coat.也可以说成,he has a coat the same as mine.但是不可以说 he has a coat the same as me.因为me和外套不能一样,不是同一类.

B

填had had.
应该用完成时态,因为主句是过去式,所以宾语从句用过去完成时.
