Grammar Focus
祈使句
1．定义：祈使句用于表达命令、请求、劝告、警告、禁止等含义。祈使句最常用于命令，因此也被称为命令句。祈使句的主语通常为第二人称you，经常省略。故祈使句通常以动词原形开头，也常以“be＋形容词”的形式出现。
Please help him. 请帮帮他。
Open the door, please. 请打开门。
Be careful！当心！
2．否定形式：在动词原形前加don't。
Don't eat here! 不要在这里吃东西！
Don't be noisy! 别吵！
3．祈使句的其他形式：在生活中常有一些表示警告的句子，
其结构是“No＋v. ing！”或“No＋可数名词复数/不可
数名词！”意为“禁止……”。
No swimming! 禁止游泳！
No photos! 禁止拍照！
4．注意：
以let开头的祈使句，若let后的宾语是us时，其否定形式是在宾语后面加not；若let后面的宾语是第三人称时，否定形式是在let前面加don't。
Let's not do that again. 我们别再那样做了。
Don't let him come in. 别让他进来。
have to与must的用法
1）must表示一种主观的需要，而have to表示一种客观的需要，意思是“不得不”。如：
I have to attend an important meeting afternoon.
今天下午我不得不参加一个重要的会议。
Mother is out, so I have to look after the shop.
妈妈不在家，因此我不得不照看商店。
2）have to的否定形式是don't have to, 相当于needn't。如：
They don't have to buy a computer at present.
他们目前没有必要买电脑。
—Must I get up early 我必须早起吗？
—No, you needn't. 不，你不必。(√)
—No, you don't have to. 不，你不必。(√)
—No, you mustn't. 不，你禁止(早起)。(×)

Writing
Dear Jack,
I’m not happy these days. I have too many rules to contain the spread of the novel coronvirous. I have to get up at 7:30 in the morning. I have to make breakfast for my family. I can’t be late for the online classes. I can’t watch TV, either. On weekends, I must clean my room and wash my clothes. I have to go to bed at 9:00 every night. I have to wear a surgical mask if I need to go out. And I have to exercise for half an hour at home. I feel boring and I don’t have any fun every day. What about you
Yours,
Li Qiang
