二 能力提升题 阅读对话, 判断句子正 (T) 误 (F)。
A: Wow! We are at the zoo!
B: Yes. What's this?
A: It's a giraffe. It's so tall.
B: Yes, and it's also thin. What's that?
A: It's an elephant. It's big and fat. Look! What are they?
B: They are tigers. Do you like them?
A: Yes, I do. They are so cool!
□ 1. This is a giraffe.
□ 2. That is a tiger.
□ 3. The elephant is big and fat.

【解析】：
1. 根据对话中的“A: It's a giraffe.”可以确认第一个句子“This is a giraffe.”是正确的。
2. 对话中提到“B: They are tigers.”，说明“that”指代的是多个老虎，因此第二个句子“That is a tiger.”是错误的，因为它暗示“that”只指代一个老虎。
3. 对话中“A: It's an elephant. It's big and fat.”直接支持了第三个句子“The elephant is big and fat.”的正确性。
【答案】：
1. T
2. F
3. T
