A.knock over them
B.knock them over
C.knock them off
D.knock off them
A.knock over them
B.knock them over
C.knock them off
D.knock off them
答案：B
解析：
1. 动词+副词型短语中，代词作宾语时需置于动词与副词之间，因此排除A、D选项；2. 辨析短语含义：knock over意为“打翻，撞倒”，knock off意为“打掉”等，结合语境“小心桌上的瓶子”，此处应表示孩子可能打翻瓶子，故选择knock them over；3. 综上，正确选项为B。
() 2.Our Chinese teacher was so satisfied Jim's article that he read it to us in class.
A.to
B.about
C.on
D.with
A.to

A.high
B.low
C.expensive
D.cheap
A.high
B.low
C.expensive
D.cheap

A.have; on
B.have; in
C.be; on
D.be; in
A.have; on
B.have; in
C.be; on
D.be; in
答案：C

1. there be句型的将来时结构为“there is/are going to be”，不能与have连用，排除A、B选项；2. 具体节日前用介词on，排除D选项，因此选C。
() 5.I you to be here from 9 to 11 o'clock, at the very least.
A.let
B.expect
C.keep
D.make
A.let
B.expect
C.keep

答案：B
解析：
本题考查动词固定搭配：
A. let：用法为let sb do sth（让某人做某事），后接不带to的不定式，不符合题干结构；
B. expect：用法为expect sb to do sth（期待某人做某事），后接带to的不定式，符合题干结构且语义通顺；
C. keep：用法为keep sb doing sth（让某人持续做某事），后接动名词，不符合；
D. make：用法为make sb do sth（使某人做某事），后接不带to的不定式，不符合。
综上，正确选项为B。
A. let：用法为let sb do sth（让某人做某事），后接不带to的不定式，不符合题干结构；
B. expect：用法为expect sb to do sth（期待某人做某事），后接带to的不定式，符合题干结构且语义通顺；
C. keep：用法为keep sb doing sth（让某人持续做某事），后接动名词，不符合；
D. make：用法为make sb do sth（使某人做某事），后接不带to的不定式，不符合。

答案：A

A.cookie
B.yard
C.fall

B.as a result
C.because of
D.in order to
A.so that
B.as a result
C.because of
D.in order to
答案：D

本题考查目的状语的表达。A.so that后接从句，空格后是动词原形have，不符合；B.as a result表结果，用法不符；C.because of后接名词、代词或动名词，不能接动词原形；D.in order to后接动词原形，表目的，符合题意。
() 9.—Will the robot any bad changes to your life? —Maybe it will.
A.bring
B.take
C.carry
D.catch
A.bring
B.take
C.carry
D.catch
答案：A
解析：
本题考查动词固定搭配。“bring changes to...”为固定表达，意为“给……带来变化”，符合语境。选项B（take）表示带走，选项C（carry）侧重搬运，选项D（catch）意为抓住、赶上，均不符合题意。因此选A。
() 10.—How often do you think your robot should be checked? —.
A.Very long
B.One year
C.In two years
D.Every two months
A.Very long
B.One year
C.In two years
D.Every two months

() 11.The woman carefully the eggs on the table and went into the kitchen.
A.lied
B.lay
C.laid
D.lain
A.lied
B.lay
C.laid
D.lain
答案：C
解析：
首先区分lie和lay的用法及变形：
1. lie表“躺；位于”时，过去式为lay，过去分词为lain；表“说谎”时，过去式为lied。
2. lay表“放置；下蛋”时，过去式和过去分词均为laid。
题干中动作是“放置鸡蛋”，且与went（过去式）并列，需用过去式，因此选laid对应的选项。
1. lie表“躺；位于”时，过去式为lay，过去分词为lain；表“说谎”时，过去式为lied。
2. lay表“放置；下蛋”时，过去式和过去分词均为laid。
题干中动作是“放置鸡蛋”，且与went（过去式）并列，需用过去式，因此选laid对应的选项。
() 12.The teacher found that Sam and often gave him some different homework to do.
A.was clever boy
B.was a clever boy
C.a clever boy
D.clever
A.was clever boy
B.was a clever boy
C.a clever boy
D.clever
答案：B
解析：
首先，"found"后接宾语从句，从句需具备完整的句子结构。分析选项：A选项中可数名词单数"boy"前缺少冠词"a"，语法错误；C选项缺少谓语动词，无法构成完整的宾语从句；D选项缺少系动词"was"，不能形成主系表的完整结构；B选项"was a clever boy"与主语"Sam"构成完整的主系表结构，符合宾语从句的语法要求。
() 13.The little girl didn't know .
A.what to do it
B.what could she do
C.how to do it
D.how to do
A.what to do it
B.what could she do
C.how to do it
D.how to do
答案：C
解析：
①“疑问词+不定式”结构中，what可作do的宾语，A选项多了it，表述错误；how是方式副词，do后需接宾语，D选项缺少宾语，表述错误。②宾语从句需用陈述句语序，B选项为疑问句语序，不符合要求。③C选项结构正确，符合语法规则。
() 14.We must do everything we can waste water from running into rivers.
A.prevent
B.prevented
C.preventing
D.to prevent
A.prevent
B.prevented
C.preventing
D.to prevent
答案：D
解析：
句子中"we can"是省略that的定语从句，修饰先行词everything；空格处需用动词不定式作目的状语，表“阻止废水流入河流”的目的，因此选不定式形式to prevent。
() 15.My hair needs . I want to have it this afternoon.
A.to cut; cutting
B.cutting; to cut
C.cut; cutting
D.cutting; cut
A.to cut; cutting
B.cutting; to cut
C.cut; cutting
D.cutting; cut
答案：D
解析：
1. 第一空：need后接动名词doing表被动含义，意为“需要被……”，头发与剪是被动关系，故用cutting；2. 第二空：have sth done是固定结构，意为“让某事被做”，此处cut为过去分词表被动，符合语境。综上选D。
二、完形填空
"When it comes to the Earth, there's no time to waste," says the Earth Day Network. And that is right. Protecting our environment is very important, and World Earth Day was created in 1970 to make people pay attention to the protection of our environment. On 22 April, people around the world celebrate Earth Day.
Every year there is a special . For example, the year 2016 is "Trees for the Earth", so Earth Day that year was all about planting trees. Their goal was to plant 7.8 billion trees the next five years.
That's a big goal, and you might wonder trees are so important. Well, for one, they can help stop climate change. Carbon dioxide (二氧化碳) is a chemical in our atmosphere, but make too much of it. Each person makes about 2.3 tons a year, which is bad for the environment.
Well, guess what! Trees carbon dioxide and improve the air quality. Planting new trees is important because people cut down trees. In 2015, there were three trillion (万亿) trees in the , about 139 billion in China. But according to Time, the world's total number has been cut in half since human civilization (文明) began. That's to say, 15 billion trees are cut down every year.
So we need to plant more to replenish (补充) the ones we've lost. One tree can take in 48 pounds (21.8 kg) of carbon dioxide per year. And it's still one of the cheapest and ways to get rid of too much carbon dioxide.
