四、阅读短文，判断句子正(T)误(F)。
Look! There are so many children in the park. What are they doing? The girl in red is reading books. The boy in a black jacket is listening to music. What are those two boys doing? They are playing football. There are three girls under the big tree. What are they doing? They are talking too loudly. Please tell them to talk quietly.
()1. There are so many children in the park.
()2. The girl in red is reading books.
()3. The boy in a yellow jacket is listening to music.
()4. Two boys are playing football.
()5. There are three girls talking quietly under the big tree.

1. T
2. T
3. F
4. T
5. F

我们可以将每个句子和短文原文逐一对照判断：
1. 短文第一句直接提到"Look! There are so many children in the park."，和题目句子表述完全一致，所以该句正确。
2. 短文中明确说明"The girl in red is reading books."，和题目句子表述完全一致，所以该句正确。
3. 短文中描述的是"The boy in a black jacket is listening to music."，并非穿黄色夹克的男孩，和题目句子不符，所以该句错误。
4. 短文中提到"What are those two boys doing? They are playing football."，和题目句子表述完全一致，所以该句正确。
5. 短文中说明大树下的三个女孩"are talking too loudly"，并不是在小声说话，和题目句子不符，所以该句错误。
