() 12. —Whose jump rope is this?
—It belongs to . She likes pink.

A.Lily's
B.Lily
C.Peter
D.Peter's

B

首先，固定搭配belong to后需接人名或人称代词宾格，不能接名词所有格，因此排除A、D选项；其次，后文的She表明对应的人是女性，Peter是男性名字，排除C选项，最终选B。

() 13. My parents always encourage me hard to achieve my dream.

A.study
B.studying
C.to study
D.studies

C

本题考查固定搭配encourage sb. to do sth.，意为“鼓励某人做某事”，因此空格处需要填入动词不定式结构to study。

() 14. We exercise a lot to keep fit.

A.ours
B.we
C.our
D.us

D

本题考查人称代词的用法，动词keep后需要接人称代词的宾格作宾语。A是名词性物主代词，B是作主语的人称代词主格，C是后面必须接名词的形容词性物主代词，只有D选项us是we的宾格，符合keep sb. fit的搭配要求。

() 15. Healthy eating means eating healthy food and good eating habits.

A.having
B.to have
C.has
D.have

A

本题考查并列结构和固定搭配mean doing sth的用法。and连接两个并列的宾语，前面是动名词短语eating healthy food，空格处要和其形式保持一致，使用动名词having。

() 16. I don't like eating apples. , I often have pears, bananas and oranges.

A.Because
B.Instead
C.And
D.But

B

辨析各选项含义：A. Because表原因，后面需要接解释不喜欢苹果的理由，不符合语境；B. Instead意为“相反、取而代之”，可放在句首作状语，契合“不喜欢吃苹果，常吃其他水果”的语义；C. And表并列顺承，逻辑不符；D. But表转折，此处不存在转折逻辑。由此确定正确选项。

() 17. Eating fast food may cause heart problems.

A.much too
B.many too
C.too many
D.too much

D

先辨析各选项用法：1. much too 用于修饰形容词/副词，不符合本题语境；2. many too 是不存在的错误搭配；3. too many 用于修饰可数名词复数，而fast food是不可数名词，不符合要求；4. too much 用于修饰不可数名词，符合本题“吃太多快餐可能引发心脏问题”的语义要求。

() 18. I eat all kinds of , but I don't eat snacks.

A.choices
B.vegetables
C.coffee
D.menus

B

理解句子含义为“我吃各种各样的______，但我不吃零食”。逐一分析选项：A.choices意为选择，不符合“吃”的逻辑搭配；B.vegetables意为蔬菜，属于可食用的食物，all kinds of vegetables表示各种各样的蔬菜，符合句意；C.coffee意为咖啡，是饮品，和动词eat不匹配；D.menus意为菜单，不符合吃的逻辑。因此正确选项是B。

() 19. If you don't eat breakfast, it's hard to our work or studies.

A.put on
B.keep away
C.focus on
D.go with

C

辨析各选项短语含义：A.put on意为穿上/增重；B.keep away意为远离；C.focus on意为专注于；D.go with意为伴随。结合句子语境“不吃早饭很难在工作和学习上集中注意力”，只有C项语义符合逻辑。

() 20. This year, my goal is to be fit. I use an app to help me.

A.hardly
B.really
C.recently
D.friendly

B

辨析各选项词义：A. 几乎不；B. 真正地；C. 最近；D. 友好的。此处需要修饰形容词fit，结合后半句“我用APP辅助自己”的语境，要表达的目标是真正达到健康的状态，只有B项语义和用法都符合。

这是一篇记叙文，讲述了想要减肥的David购买健身器材后多次更换摆放位置，却始终没有真正坚持锻炼的小故事，逐题解析如下：
1. 由首句David太胖想要减肥可知，他买的是健身器材，"exercise machine"是固定搭配，意为健身器材，符合语境。
2. 句意为他一开始把这台机器放置在地下室，"put sth. in sp."是常用表达，意为把某物放在某处，符合语境。
3. 前文提到地下室不是适合锻炼的舒适场所，他几乎不使用这台机器，因此他很少去地下室，seldom表示很少，符合语境。
4. 前文提到他认为把机器放在卧室会更好，因此他把机器搬到了自己的卧室，符合上下文逻辑。
5. 句意为他走进卧室的时候总是很疲惫，只想快点睡觉，结合卧室的场景，sleep符合语境。
6. 后文提到了窗帘，窗帘是挂在窗户上的，因此他把机器放在了窗户旁边，符合后文提到窗帘的设定。
7. 句意为几天后他的妻子询问他锻炼进展如何，asked表示询问，符合语境。
8. 句意为每次我想要拉开窗帘，我都得绕着这台机器走，open符合此处动作搭配。
9. 句意为从这个故事我们能看出David想要做出改变，但并没有好好落实他的计划，follow his plan是固定表达，意为执行/落实他的计划，符合语境。
10. 句意为如果我们想要达成目标，我们需要更加认真对待，serious意为认真的、严肃的，符合故事传递的道理。
