Ⅲ.单项填空
1．The two girls are so alike that strangers find________difficult to tell one from the other.
A．it
B．they
C．her
D. that
答案 A [考查代词用法。
句意：两个女孩长得如此相像以至于陌生人都发现很难区分开来。it在句中充当形式宾语，代替后面的真正的动词不定式宾语to tell one from the other，故选A项。]
2．Does________matter if he can't finish the job on time?
A．this
B．that C．he
D．it
答案 D [matter作动词时，在疑问句或否定句中用it作主语，然后把whether引导的从句位于句末。]
3．I was disappointed with the film. I had expected________to be much better.
A．that
B．this
C．one
D．it
答案 D [it 特指the film。C项有一定干扰性。one 在此等于a film。]
4．Helping others is a habit，________you can learn even at an early age.
A．it
B．that
C．what
D．one
答案 D [考查代词作同位语。句意：帮助他人是习惯，是一种甚至年幼时你就能学着养成的习惯。设空处作a habit的同位语。one用来代替前面出现的泛指的单数名词a habit，以避免重复。故选D项。]
5．You promised to write the article, so you must________.
A．do writing
B．do writing it
C．write an article
D．do it
答案 D [do it指 write the article, C项属于冠词使用错误。]
6．I like this house with a beautiful garden, but I don't have enough money to buy________.
A．one
B．it
C．this
D．that
答案 B [考查替代词的用法。句意：我喜欢这套前面带美丽花园的房子，但我没有足够的钱买它。one与that作替代词时常表示“同类不同物”，其中one代替前面提到的表泛指的单数名词；that替代特指的单数名词或特指的不可数名词；this一般不用作替代词；it表示同类同物，替代前面的特指的单数名词或不可数名词。本题表同类同物，it替代前面提到的this house，故选B项。]
7．—Is it going to snow tonight?
—I'm afraid________.
A．it
B．that
C．so
D．this
答案 C [本空极易错选A项。afraid为形容词，后面不能直接跟名词或代词作宾语。so在本句中指代上文中的观点。]
8．Isn't it amazing how the human body heals________after an injury?
A．himself
B．him
C．itself
D．it
答案 C [考查反身代词的用法。句意：人的身体在受伤后会自动痊愈，这不令人惊奇吗？根据句意，空白处应用反身代词，the human body的反身代词是itself，故选C项。]
9．Nothing can stop us，________？
A. can't it
B．can it
C．can't we
D．can we
答案 B [本句的主语是nothing, 第二次提到 nothing, anything, everything, this, that，用it。在本句中it相当于anything。]
10．—Do you like________here?
—Oh, yes. The air, the weather, the way of life. Everything is nice.(2017·杭州高二检测)
A．these
B．that
C．that
D．it
答案 D [考查代词it的用法。句意：——你喜欢这里吗？——噢，是的。(我喜欢)这里的空气、天气、生活方式。这里的一切都是美好的。it用来指代下句中的the air，the weather, the way of life，其他代词都无此用法，故选D项。]
11．________the harder you work, the better result you'll get.
A．It's believed that
B．What we believe that
C．It's fact that
D．What the fact is
答案 A [It's believed that为固定搭配，意思是“人们相信”，其中it为形式主语，真正的主语为that 从句。]
12．The doctor thought________would be good for you to have a holiday.
A．this
B．that
C．one
D．it
答案 D [考查it作形式主语。句意：医生认为度假对你有好处。句中不定式短语to have a holiday在宾语从句中作真正的主语，只有it可作形式主语，故选D项。]
13．________is a pity that you forgot both her address and her telephone number.
A．That
B．This
C．It
D．There
答案 C [It is a pity that为固定搭配，意思是“太可惜了”，其中it 是形式主语。]
14．Being a parent is not always easy, and being the parent of a child with special needs often carries with________extra stress.
A．it
B．them C．one
D．him
答案 A [考查代词it的用法。句意：做家长并不总是很容易，做一个有特殊需求的孩子的家长更有压力。it指代上文出现的“being the parent of a child with special needs”。 故选A项。]
15．________needs further discussion whether we'll build a library or not.
A．We
B．He
C．It
D．The thing
答案 C [it为形式主语，真正的主语为whether 引导的从句。D有一定干扰性。 若用the thing 作主语，放在句末的whether从句多余。]
