Task 5：选择正确的选项。
```
()1. —______?
—He's Bai Bin.

A.How is he
B.How old is he
C.What's his name

C

根据答语“He's Bai Bin.”可知问句询问的是他的名字。A选项“How is he”询问他怎么样，B选项“How old is he”询问他的年龄，C选项“What's his name”询问他的名字。故正确选项为C。

()2. —Is that ______ English book?
—Yes. It's his ______ book.

A.an; a
B.an; /
C.the; /

B

第一空询问“那是一本英语书吗”，English以元音音素开头，需用不定冠词an；第二空回答“是他的英语书”，名词所有格his后不需要冠词，直接接名词book。因此选择an; /。

 ()3. —______?
—No, I'm Bob.

A.Are you Tony
B.Are you Bob
C.Is this your friend, Tony

A

根据答句"No, I'm Bob."可知，问句是询问对方是否是某人，且对方回答不是，自己是Bob。选项A"Are you Tony"意为“你是Tony吗”，符合语境；选项B"Are you Bob"与答句中“我是Bob”矛盾；选项C"Is this your friend, Tony"是询问这是否是对方的朋友Tony，答句应回答是否是朋友，而非自己是谁。所以选A。

()4. Tom is ______ good friend. ______ in ______ China now.
A.my; He's; the
B.my; He's; /
C.her; She's; the

B

第一空后有名词"friend"，需用形容词性物主代词，Tom为男性，排除C；"China"是专有名词，前面不加定冠词"the"，排除A，选B。

()5. Your English teacher is Mary Smith, so you can call her ______.
A.Ms Smith
B.Ms Mary
C.Mr Smith
```

A

在英语中，称呼老师时，通常用“Ms+姓氏”。Mary Smith中Mary是名字，Smith是姓氏。“Ms”用于女性，“Mr”用于男性，题目中是女老师，所以排除C。B选项“Ms Mary”用了名字，不正确。A选项“Ms Smith”符合“Ms+姓氏”的用法。
