You may come here whenever you like.
你想什么时候来就什么时候来。
2.当对现在及将来正在发生的动作进行推测时，一般用can /
could, may / might, must + be + doing（动词的进行时）。
e.g. — Where is Cindy Cindy在哪儿呢？
— It’s a fine day. She may / might be enjoying the sunshine
on the lawn.
今天天气好，她很可能在草坪上晒太阳呢。
Your sister can’t be touring Nanjing. I saw her just now.
你姐姐根本不可能在南京旅游，我刚刚还看见她呢。

用法
must与have to的区别
have to比较强调客观需要，must着重说明主观看法。
另外have to能用于更多时态, 比较下面的句子：
We had to be there at 10:00.
有时两者都可以用, 意思差别不大。
We must have to leave now.
must在表示说话人对事物的推测时候要注意它，比may肯定得多, 相当于汉语的“一定”或“是”。(只有在肯定句中能这样用。)
This must be your room．
　在回答由must引起的问题时, 如果是否定的答复，不能用mustn’t, 而需要用needn’t 或 don’t have to, 因为mustn’t是“一定不要”的意思。
连词是一种连接词与词、短语与短语以及句与句的虚词，它不能独立担任句子成分而只起连接作用。
表示结果的连词有: so (所以)等；
表示原因的连词有: because, since, as等；
表示意义转折的连词有: but, however, though；
表示递进意义，not only... but also...“不仅……而且”；
表示选择关系的连词有: or (或者；还是)；
表示两件事情同时发生的连词有: when, while等。

No More Mystery in the Neighborhood
Last week, in a quiet neighborhood, something strange happened. Residents heard noises in the night but no one knew why. Victor thought that it was teenagers having fun while his wife and neighbor, Helen, blamed it on animals.
【示例】
We now know what was happening in the neighborhood. A ranger’s station(护林站)is being built in the nearby forest.
Trees had to be cut down to make space for the station. This affected some animals living in the forest. A raccoon(浣熊)family lost their home and had problems finding food.
The raccoons discovered food in the neighborhood’s garbage bins(垃圾桶),so they came back every night.
Now the mystery is solved. People in the neighborhood feel sorry for the raccoons and they are trying to help them.
