一、圈出你所能找到的单词并把它们写下来

usually、sometimes、mountain、season、second、weekend、birthday、because、lunch、car

我们可以沿着横向、纵向两个方向，在字母方阵里寻找连续排列的、符合五年级英语学习范围的常见单词，逐一排查后即可得到所有符合要求的单词。

二、读一读,圈一圈,写一写
1. My mother usually (cooks / cooking) at 5:30 p.m. It is 5:30 p.m. now. But she is (watches / watching) TV. Because it is Mother's Day. Look at my father. He is (cooks / cooking) now.
2. Usually I (go to bed / going to bed) at 9:00 p.m. But it is 9:30 p.m. now, I am still (watch TV / watching TV). Because today is Friday.
3. I often (play computer games / playing computer games) in the evening. But this evening I am (swim / swimming) in the pool. Because it is too hot.
4. Usually I don't (clean / cleaning) my room in the evening. But this evening I am (clean / cleaning) my room. Because my friends are coming.

1. cooks; watching; cooking
2. go to bed; watching TV
3. play computer games; swimming
4. clean; cleaning

本题考查一般现在时和现在进行时的基础用法，符合五年级知识点要求：
1. 当句中出现usually（通常）、often（经常）这类表示经常性、习惯性动作的标志词时，要用一般现在时：主语是第三人称单数时，谓语动词用第三人称单数形式；主语是第一人称I时，谓语动词用原形；助动词don't后面必须接动词原形。
2. 当句中出现now（现在）、句中存在am/is/are这类be动词时，要用现在进行时，结构为"be动词+动词的ing形式"，表示当下正在发生的动作。
逐空判断：
1. 第一空有usually，主语my mother是第三人称单数，选cooks；第二空前有be动词is，选watching；第三空后有now、前有be动词is，选cooking。
2. 第一空有usually，主语是I，选go to bed；第二空前有be动词am，选watching TV。
3. 第一空有often，主语是I，选play computer games；第二空前有be动词am，选swimming。
4. 第一空在助动词don't之后，要接动词原形，选clean；第二空前有be动词am，选cleaning。
