【解析】①get to与地点副词（here/there/home…）不用介词to
E.g. I want to go to Beijing.
I got home at 15:00.
②arrive是不及物动词，后面若接地点名词则要和in/at连用，接地点副词时则不用介词。
E.g. I arrived home at 15:00. = I got home at 15:00.
He arrived in Shanghai yesterday.
③reach是及物动词，后面直接接地点名词或副词。

三、重点语法
1. 情态动词have to的用法
意思是“必须、不得不”，它侧重于客观上的必要和外界的权威。 
●结构：主语+have to+动词原形+其他 
●一般现在时：主语是第三人称单数时用has to，其它时候用have to
（过去时：无论人称和单复数都用had to）
E.g. We have to wear sneakers（运动鞋）for gym class.
Tom has to practice the guitar every day.
I had to get up at 5:00 am last Monday. 
●否定形式：主语+don't have to+动词原形+其他
●一般现在时：主语是第三人称单数时用doesn't have to, 其它时候用don't have to
（过去时：无论人称和单复数都用didn't have to）
E.g. Nick doesn't have to wear a uniform.
We didn't have to do our homework at once. 
●疑问句：Do, Does或Did+主语+have to +动词原形+其他
E.g. —Do you have to stay at home on weekends? 
—Yes, I do. / No, I don't.
Did he have to go to bed by 11:00 last night?

2. 情态动词must的用法
must表示说话人的主观看法，及主观上的必要性，还用于命令或愿望。只用于现在时，无人称和单数的变化。在表示过去、将来和完成时，用have to的相应形式来代替must.
●在表示有做某一个动作的必要和义务，它的意思是“必须，应该”。
E.g. You must finish your homework first.
●表示有很大把握的判断或者推测，意思是“一定，准是”。
E.g. The tall man must be your father.
●以must开头的一般疑问句，它的否定回答用needn’t（不必要），不用mustn’t（不允许），mustn’t常用于否定句中表示“不允许，禁止”。
E.g. —Must I go there on foot?
—No, you needn’t.
You mustn’t park your car here.

3.情态动词can的用法
①表示能力：“会；能”，
E.g. Can you play the guitar?
Judy can speak a little Chinese.
I can dance and sing.
②表示允许、许可：“可以；能”
E.g. Can the students run in the hallways（走廊）?
We can eat outside.
Can I come in?
【注】同样是情态动词can 和have to 的用法是有区别的，和大部分情态动词一样，can在否定句中直接在can后加上not；在疑问句中把can放到主语前面，并且没有人称和数的变化，而 have to 是有相应变化的。
4. 祈使句（Imperative Sentence）
●定义：用于表达命令、请求、劝告、警告、禁止等的句子叫做祈使句，祈使句最常用于表达命令，因此有时也常称为命令句。
●祈使句因对象（即主语）是第二人称，所以通常都省略。祈使句的动词都为一般现在时，句末则使用句号或感叹号来表示结束。
●祈使句的肯定句：行为动词原形+其他
E.g. Go and wash your hands. 去洗你的手。——命令
　 Be quiet, please.= Please be quiet. 请安静。——请求
　 Be kind to our sister. 对姐妹要和善。——劝告
　 Watch your steps. 走路小心。——警告
　 Look out！Danger！ 小心！危险！——强烈警告
　 Keep off the grass. 勿践草坪。——禁止
　 No parking. 禁止停车。——禁止
●以Let开头的祈使句，Let后宾语是是第一人称时，否定形式是在宾语后加not,
E.g. Let’s not do that again.我们别再那样做了。
如果Let 后面宾语是第三人称，否定形式是在Let前加助动词Don’t,
E.g. Don’t let them come in.别让他们进来。
●祈使句的否定通常使用“Don't …”，Don't+动词原形（行为动词/be动词）+其他
E.g. Don't let the dog in.
　 Don't touch（触摸）, please.
　 Don't be silly.
●祈使句有时也把主语“You”表达出来，使对方听起来觉得柔和些
E.g. You go and tell him, Chris.
