Task 5 老师提供了一份介绍自己的小发明的短文作为参考，你需要快速阅读，判断下列句子正(T)误(F)。
Hello! I'm Tom. Last week, I invented a cleaning brush for our class. It's useful for us. We always have trouble cleaning the blackboard gaps. So I made this brush to solve the problem. I used an old brush, a small piece of wood and some tape to make it. First, I prepared the old brush and the wood. Next, I tied the brush to the wood with tape. Then, I polished the wood carefully. Finally, I painted it blue. It was easy to make it. Now, we can clean the blackboard gaps easily. I'm proud of my invention.
()1. Tom invented the cleaning brush yesterday.
()2. Tom used an old brush, wood and tape to make the brush.
()3. First, Tom tied the brush to the wood.
()4. The brush can help clean the blackboard gaps easily.
()5. Tom thinks it was difficult to make the brush.

1~5 F T F T F
1. 根据短文中“Last week, I invented a cleaning brush for our class.”可知，清洁刷是上周发明的，并非昨天，题干表述错误，故填F。
2. 根据短文中“I used an old brush, a small piece of wood and some tape to make it.”可知，制作清洁刷的材料与题干表述一致，题干表述正确，故填T。
3. 根据短文中“First, I prepared the old brush and the wood. Next, I tied the brush to the wood with tape.”可知，第一步是准备材料，并非把刷子绑在木头上，题干表述错误，故填F。
4. 根据短文中“Now, we can clean the blackboard gaps easily.”可知，该清洁刷可帮助轻松清理黑板缝隙，与题干表述一致，题干表述正确，答案为T。
5. 根据短文中“It was easy to make it.”可知，作者认为制作该清洁刷很容易，并非困难，题干表述错误，故填F。

【分析】本题为英语阅读理解正误判断题，解题思路为：首先快速通读短文，掌握短文核心内容（汤姆发明清洁刷的时间、制作材料、步骤、用途及制作感受）；接着逐题分析，定位题干表述在短文中的对应句子；最后对比题干与原文细节是否一致，判断正误。
【解析】1. 原文提到“Last week, I invented a cleaning brush”，题干说“yesterday”，时间不符，故填F；2. 原文明确“used an old brush, a small piece of wood and some tape”，与题干表述一致，故填T；3. 原文制作步骤中“First”是准备材料，“Next”才是绑刷子，题干将步骤顺序混淆，故填F；4. 原文提到“Now, we can clean the blackboard gaps easily”，与题干表述一致，故填T；5. 原文说“It was easy to make it”，题干说“difficult”，表述相反，故填F。
【答案】1.F 2.T 3.F 4.T 5.F
【知识点】英语阅读理解、细节理解
【点评】本题考查英语阅读理解中的细节判断能力，需学生准确提取原文细节信息，难度适中，只要仔细阅读即可正确解答。
