请问几道英语题的理由``急吖``

4.He is an experienced teacher.That is to say ,he has (C).
A.many experiences B.much experiences
C.a lot of experience D.little experience
experience作经验解释时,为不可数名词,作经历解释时,为可数名词.根据这句话的意思,可以判断AB都不对.D的话呢,little有否定含义,和前面的语境不合,因此选C,a lot of即可修饰可数也可修饰不可数名词.
5.The teacher praised Jack,because he had made (A).
A.great progress B.great progress
C.a great progress D.little progress
progress为不可数名词,不能加定冠词.D还是与前面语境不合.
7.(D) it is to listen to music after dinner!
A.How fun B.What a fun C.What funny D.What fun
感叹句的句型 how+adj+主+宾.what + a,an+adj+n.fun为不可数名词.A改为how funny就对勒 .
9.These are (D) and one of them is a yellow deer;those are (D) and one of them is a white horse.
A.deers;horses B.deer;horse C.deers;horse D.deer;horses
deer,意思是鹿,单复数同型,因此不加-s.horse可数名词,复数要加-s.
10.I met some (B) on my way to school.
A.Chinese B.Russians C.Germen D.Swisses
12.Will you have a little (B)?
A.more fishes B.more fish C.much fishes D.fishes
这题考察比较级前面的可用a little来修饰.fish一般做不可数名词来用,因此不加-s.
14.I need to buy some (A).
A.tooth brushes B.tooth brushs
C.teeth brushes D.teeth brushs
这里的牙刷,tooth是名词当形容词来用,因此复数只要加在后面的brush就可以勒.
16.The washing machine cost the family five hundred (A).
A.yuan B.yuans C.dollar D.of dollar
货币dollar要加-s,人民币yuan不用.
