情境应用
1. Pandas live on bamboo
shoots
and leaves, and most of them live in China. (shoot)
2. He
shot
down an apple off the tree with a stone just now. (shoot)

答案

1. shoots
2. shot

解析

1. 本题需要根据句子意思，选择所给词“shoot”的适当形式填空。bamboo为名词“竹子”，空格处应为名词修饰名词的结构，故本空应为名词“嫩芽”shoot，竹嫩芽不止一个，故应为复数形式。
2. 本题需要根据句子意思，选择所给词的适当形式填空。shoot down为“射下”，根据just now可知本句时态为一般过去时，shoot的过去式为shot。
探究点2 feel free (to do sth)的用法
feel free to do sth 意为“可以随便做某事”,这是英语口语中的一个常用表达。
- If you need any help, feel free to ask. 如果你需要任何帮助,随时开口。
情境应用
1. Please feel free
to call
me at 4032 - 6166 if you would like to give help! (call)
2.
Feel free
to make yourself at home and help yourself to some snacks. (随意)

答案

1. to call；2. Feel free

解析

1. "feel free to do sth"为固定搭配，意为“可以随便做某事”，故此处应填动词不定式"to call"。
2. 该句为祈使句，表达“随意”应用"Feel free"，句首首字母需大写。

A.popular
B.more popular

D
) 2. Giraffes like eating ______, and pandas like eating ______.
A.leaf; bamboo
B.leafs; bamboo
C.leaf; bamboos
D.leaves; bamboo

答案

D

解析

本题考查名词的复数形式。“leaf”（树叶）的复数形式应为 “leaves”，是以 “f” 或 “fe” 结尾的名词变复数时，将 “f” 或 “fe” 变为 “v” 再加 “es”；“bamboo”（竹子）是不可数名词，没有复数形式。所以长颈鹿喜欢吃树叶，熊猫喜欢吃竹子应表达为 “Giraffes like eating leaves, and pandas like eating bamboo.”

—No. ______, she is an English teacher.

A.Finally
B.Carefully
C.Actually

答案

C

解析

问句询问Ann是否在医院工作，答句先否定，后说明她是英语老师。"Actually"意为“实际上”，符合语境，用于纠正或补充说明事实。A项“Finally”（最后）、B项“Carefully”（仔细地）、D项“Hardly”（几乎不）均不符合句意。

D.Like what?

答案

A

解析

根据对话语境，对方说这是第一次去长城，回答者表示惊讶“不敢相信你从未去过，你到北京快一年了”，“Really?”符合惊讶、难以置信的语气，用于回应对方的陈述。B项“那是什么？”、C项“对吗？”、D项“比如什么？”均不符合语境。

B选项“Never mind!”（没关系）用于安慰或回应道歉，不适用。
C选项“You're welcome.”（不客气）用于回应感谢，不适用。

解析

1. "good"的名词形式为"goodness"，表示"美德"，符合句意"互相帮助是一种优秀的美德"。
2. "didn't"后接动词原形，故填"appear"。
3. 根据"yesterday"可知用一般过去时，"shoot"的过去式为"shot"。
4. "seem to do sth"为固定搭配，意为"似乎做某事"，故填"to know"。
5. "one of the + 形容词最高级 + 名词复数"表示"最……之一"，"use"的形容词为"useful"，最高级为"most useful"。
6. 修饰动词"treat"用副词，"exact"的副词形式为"exactly"。
7. "use sth to do sth"为固定搭配，意为"用某物做某事"，故填"to build"。
