Be careful while crossing the road.过马路时要小心。
Don't forget to turn off the lights！不要忘记关灯！
三、重点预习
Don't arrive late for class.You must be on time.上课不要迟到，你必须准时。(P19，1a)
重点1
(2)①arrive late for...意为“(做)……迟到”，相当于be late for。arrive late for侧重到达的时间晚，be late for 侧重于状态。
I hope you will not arrive late for school again.
＝I hope you will not be late for school again.
我希望你上学别再迟到了。
②arrive为不及物动词，意为“到达，抵达”，其后跟介词in或at，in后接大地方，at后接小地方，此时相当于get to。arrive 和get后若是地点副词，则不需要加介词。
When did you arrive in Beijing？你什么时候到北京的？
He arrives at the bus stop at six.他六点钟到公共汽车站。
He arrives home at 5：00 in the afternoon.他下午五点钟到家。
(3)must为情态动词，意为“必须；一定”，表示说话人主观上的看法。情态动词不能单独作谓语动词，必须和动词原形一起构成谓语。
I must leave at six today.我今天必须六点钟离开。
【拓展】①用于否定句时，mustn't意为“千万不要；禁止”，而不表示“不必”。
You mustn't phone him this evening.
今天晚上你千万不要给他打电话。
②由must构成的一般疑问句，它的肯定回答用must，否定回答用needn't或don't/doesn't have to(不能用 mustn't)。
—Must I clean the room now？我必须现在打扫房间吗？
—Yes，you must./No，you needn't/don't have to.
是的。/不，你不必。
(4)on time意为“准时；按时”，指按规定或指定的时间做某事；in time意为“及时”，指不迟到或在规定的时间之前或接近规定的时间做某事。
We must arrive there on time.我们必须准时到达那里。
At last，we reached the park in time.最后，我们及时到达了公园。
