()5. I think buying books online can us a lot of money.

A.guess
B.save
C.carry
D.raise

B

辨析各选项词义：A. guess 猜测；B. save 节省；C. carry 携带；D. raise 筹集。句意为“我认为网上买书能为我们省下很多钱”，save sb. a lot of money符合语境，情态动词can后接动词原形，因此选B。

()6. I can't have a picnic with you because I have to my sister at home.

A.look at
B.look like
C.take photos
D.take care of

D

先辨析各选项短语含义：A. look at 意为“看”；B. look like 意为“看起来像”；C. take photos 意为“拍照”，该短语不能直接后接人物对象；D. take care of 意为“照顾”。结合句子语境“我不能和你去野餐，因为我必须在家照顾我的妹妹”，只有D选项符合语义逻辑。

()7. Now schools some of the homework, so students can have more free time to do something they like.

A.put up
B.work out
C.cut down
D.prepare for

C

先辨析各短语含义：A. put up 意为张贴、搭建；B. work out 意为计算出、解决；C. cut down 意为削减、减少；D. prepare for 意为为……做准备。根据后半句“学生可以拥有更多空闲时间做自己喜欢的事”，可知学校是减少了部分作业，只有cut down符合语境。

()8. — do you like reading?
—Because reading makes a full man.

A.Why
B.What
C.How
D.When

A

答句由Because引导，用于说明原因，对原因提问需用疑问词Why，其余选项What询问内容、How询问方式、When询问时间，均不符合语境。

()9. —Sam, we're going to play ping-pong. Would you like to join us?
—Sorry, I'm not player.

A.good a quite
B.quite a good
C.a good quite
D.quite good a

B

本题考察quite的固定用法，当quite修饰带有形容词的单数可数名词时，正确结构为"quite a + 形容词 + 可数名词单数"，对比四个选项的语序，只有B符合该规则。

()10. —You are always talking about your pet cat. What does it look like?
—.

A.It likes eating fish
B.It likes playing with me
C.It's small and white
D.It likes climbing trees

C

"What does it look like?"是用于询问事物外形外貌的句型，A、B、D选项均描述猫的喜好，不符合问句要求，只有C选项描述猫的外形特征，符合语境。

二、根据句意及汉语提示完成句子。
1. There are two （狐狸）in the City Zoo.
2. Do （企鹅）live in the cold Antarctica?
3. It's （凉爽的）today.
4. Let's （拯救）the trees.
5. Whales are （巨大的）animals.

1. foxes
2. penguins
3. cool
4. save
5. huge/large

1. “狐狸”对应的英文单词是fox，空前有数词two修饰，可数名词需要使用复数形式，fox的复数变化规则为加es，即foxes。
2. “企鹅”对应的英文单词是penguin，此处指代企鹅这一类动物，要使用可数名词复数形式penguins。
3. “凉爽的”对应的英文形容词是cool，放在be动词is后作表语，直接填写形容词原形即可。
4. “拯救”对应的英文单词是save，固定结构Let's do sth. 意为“让我们做某事”，后面需要接动词原形，所以填save。
5. “巨大的”对应的英文形容词是huge，也可使用large，此处修饰名词animals，直接填写形容词原形即可。

三、用所给单词的适当形式填空。
1. I don't like (wolf) because they're dangerous.
2. The sign (say) “No photos” in the museum（博物馆）.
3. David (stand) behind Mary.
4. They are friendly with good (look).
5. There are many (mouse) in that old house.
6. These children are (play) but lovely.
7. I want to spend a (meaning) holiday.
8. Here are three nice (photo) of Jim.
9. The (swim) is from China.
10. Every wildlife (count) in nature.

1. wolves 2. says 3. stands/is standing 4. looks 5. mice 6. playful 7. meaningful 8. photos 9. swimmer 10. counts

1. 考点：可数名词复数。此处泛指狼这一类动物，要用wolf的复数形式，wolf以f结尾，变f为v再加-es，即wolves。
2. 考点：一般现在时的主谓一致。主语The sign是第三人称单数，句子描述客观事实，谓语动词say要变为第三人称单数形式says。
3. 考点：一般现在时的主谓一致。主语David是第三人称单数，描述当前的状态，谓语动词stand要变为第三人称单数形式stands，也可使用现在进行时is standing，符合语法规则。
4. 考点：名词变形。形容词good后接名词，good looks是固定表达，意为“好看的外貌”，此处用look的复数形式looks。
5. 考点：可数名词复数。many后接可数名词复数，mouse是不规则变化名词，复数形式为mice。
6. 考点：形容词变形。but连接并列的形容词，和lovely对应，要把动词play变为形容词playful，意为“顽皮的、爱闹的”。
7. 考点：形容词变形。此处需要形容词修饰名词holiday，名词meaning的形容词形式meaningful意为“有意义的”，符合句意。
8. 考点：可数名词复数。数词three后接可数名词复数，photo的复数形式直接加-s，即photos。
9. 考点：名词变形。定冠词The后接名词作主语，此处表示“游泳运动员”，动词swim对应的身份名词是swimmer。
10. 考点：一般现在时的主谓一致。主语Every wildlife是单数概念，谓语动词count要变为第三人称单数形式counts，此处意为“至关重要”。
