这几道题不会做，请大家帮帮忙，题后面的数字与题没有关系。~~~

Answer 1

1.Nine _______pounds a week?That's very good
A hundred of B hundreds of C hundreds D hundred (D)
2.Our summer holiday is coming .Two___the students in our school will go to the beach
A hundred B hundreds C hundred of D hundreds of(C)
为什么第一个不用of，第2个用？
这是由后面的pounds和students in the school 定的，因为钱是没有限量的，而后的学是代指全校学生中的一部分。
3.---Is ____here?
---No,Tom and Jack have asked for a leave
A anybody B everybody C somebody D nobody (B)
很明显由Tom and Jack have asked for a leave知，强调的是全部人是否在这里。很以用everybody
4._____will make your grandma happy if you buy a walking stick for her birthday,I guess.
---It sounds a good idea !She has some problems walking now
A that B It C this D what (B)
做这题是凭语感的，一般都是用It，这是外国人的习惯用法，要用多阅读来提升。这是没有办法解释，若要解释的话， 我想是钴牛尖。

5.---John,someone in your class phoned you this moring.
-Oh,who was______?
A he B she C it D that(C)
同上

6.--We found____necessary to protect the earth.
A it B this C that D what(A)
同上
7.---Why did ______take Aunt Alice almost an hour to get home?
-- I don't know.Maybe there was something wrong with her car.
A that B it C she D this (B)
同上
8-- I wan some large____,not small_____
A ones,its B ones,ones C these,those D those,ones (B)
these是特指的 而one是泛指的。很明显题目要的东西是同种类，但不确定是那一个啊！
9.---Help me hold the tree,please.
Ok!Is it straight?
________
A now and then B more and more C up and down D more or less (D)
外国人的习惯用法，无法解释的，只能通过运用来掌握。
10.--.---We did_____Mr. HU told us and we won the first place in the league at last.
A though B like C as Dwhile (C)
是指“正如”的意思。
还有什么不懂，可以发信息给我。

Answer 2

1.Nine _______pounds a week?That's very good
A hundred of B hundreds of C hundreds D hundred (D)
当数词hundred/thousand/million/billion/trillion前有其他数词修饰时，只用单数形式。
2.Our summer holiday is coming .Two___the students in our school will go to the beach
A hundred B hundreds C hundred of D hundreds of(C)
为什么第一个不用of，第2个用？
因为第二个有定冠词the，“the students”是一个整体，不能分开，前面必须加介词才能通顺。
3.---Is ____here?
---No,Tom and Jack have asked for a leave
A anybody B everybody C somebody D nobody (B)
考查语境。语意为：
——大家都在吗？
——不，汤姆和杰克请假了。
4._____will make your grandma happy if you buy a walking stick for her birthday,I guess.
---It sounds a good idea !She has some problems walking now
A that B It C this D what (B)
代词it作“虚主语”。其他代词都无此用法。
5.---John,someone in your class phoned you this moring.
-Oh,who was______?
A he B she C it D that(C)
考查代词it的用法。在不确定对方性别的情况下，只能用it。
6.--We found____necessary to protect the earth.
A it B this C that D what(A)
考查代词it作形式宾语的用法。真正的宾语是不定式短语“to protect the earth”，it作形式宾语代替该短语并提前。
7.---Why did ______take Aunt Alice almost an hour to get home?
-- I don't know.Maybe there was something wrong with her car.
A that B it C she D this (B)
it作虚主语。与第4题相同。
8-- I wan some large____,not small_____
A ones,its B ones,ones C these,those D those,ones (B) 33
结合句意，显然是泛指而不是特指，故用不定代词ones，而不用
指示代词these或those。its是物主代词，与题干不相关。
9.---Help me hold the tree,please.
Ok!Is it straight?
________
A now and then B more and more C up and down D more or less (D) 56
考查语境中的交际。四个选项的含义是：A、偶尔。B、越来越……。C、上上下下。D、差不多。
句意是：
——请帮我扶着点树。
——好的。它是直的吗？
——差不多吧。
10.--.---We did_____Mr. HU told us and we won the first place in the league at last.
A though B like C as Dwhile (C) 76
句意是：我们按照胡先生告诉我们的去做，最终获得了第一名。as表示“按照……”，最为恰当。

Answer 3

1,2因为第二个有the，第一句意思是900英镑，第二个意思是学生中的200个。
3.根据回答，汤姆和杰克请假了，可推断有人，但是汤姆和杰克不在。所以问的应该是所有人都在这吗？如果选A就是问有人在吗？回答应该是yesle
4.it在此时指代，指代的是walking stick拐杖，意思是如果你给你奶奶买个拐杖，她一定很高兴。
5.以前讲过，如果电话上不知道是谁，就用it来代指。
6.在此，it是found的宾语，叫做形式宾语，因为真正的宾语的to protect the earth。我们发现保护地球很必要。这种用法很常见，在make，find ，think等动词后+it+形容词（做宾语补足语）+to do（真正宾语）
7.这个用法是it+take +sb+时间段+to do，意思是花费某人某些时间干某事。可以当做句型记住，也可以按照刚才给你解释的，it是形式上的，不过在此是形式主语，真正的主语是后边的to do形式。
8.要一些大的，而不是小的。这算是泛指，而those那些人/东西是特指。
9.more or less 差不多，几乎，大约，让你帮他扶着树，然后问冲齐了吗？回答差不多。
10.as按照，我们按照胡先生告诉我们的做的。
