()1. —Mum, there's a river in the park.
—Cool!

A.Let's go boating.
B.Let's go eating.
C.Let's go climbing.

A

对话提到公园里有一条河，和河匹配的合理活动是划船。A选项意为“我们去划船吧”，符合语境；B选项“去吃东西”、C选项“去爬山”都和存在河流的场景不相符，因此选A。

()2. —Are there any trees in the park?
—Yes. There's a big here.

A.forest
B.children's center
C.lake

A

问句询问公园里是否有树，答句给出肯定回应，需要选择和树木相关的词汇。forest意为森林，里面有大量树木，符合语境；children's center（儿童中心）、lake（湖）都和问句提到的树木没有对应关联，所以选A。

()3. There are some rabbits in the .

A.waterfalls
B.mountains
C.sea

B

先分析句子含义：句子意为“有一些兔子在______里”。A选项waterfalls（瀑布）、C选项sea（大海）都不符合兔子的生存场景，B选项mountains（山）是兔子可以栖息的自然场景，符合逻辑。

()4. —Is there a lake in the mountains?
—

A.Yes, it is.
B.Yes, there is.
C.Yes, there are.

B

本题考查there be句型一般疑问句的回答规则。问句以Is there引导，对应的肯定回答固定为Yes, there is. 选项A用于回应Is it...类的问句，选项C的be动词are和问句的单数is不匹配，因此正确选项是B。

二、选择合适的句子补全对话。
A: There's a new park near my home.
B: Great! 1.
A: It's very big and beautiful.
B: 2.
A: Yes, there is. And there is a lake in it.
B: Cool! Are there any rivers in the park?
A: 3.
B: Wonderful! What do you usually do in the park?
A: 4.
B: It sounds fun. Can I go there with you this Sunday?
A: Sure. We can have a picnic there. 5.
A. That will be very interesting.
B. What's it like?
C. Yes, there are two. They're in front of a forest.
D. Is there a mountain in the park?
E. I usually go hiking and go boating with my parents on Sunday mornings.

1.B 2.D 3.C 4.E 5.A

我们可以根据上下文的问答逻辑匹配选项：
1. 空后A回答公园又大又漂亮，是描述公园的特征，对应询问公园是什么样子的B选项。
2. 空后A用"Yes, there is."作答，说明空处是Is there开头的一般疑问句，对应D选项。
3. 空处是回答上文"Are there any rivers in the park?"的提问，C选项给出了复数形式的肯定答复，符合语境。
4. 空处是回答上文询问在公园通常做什么的问题，E选项描述了自己在公园的活动，符合要求。
5. 空前提到可以在公园野餐，A选项表达“那会非常有趣”，承接上文语义通顺。
