Language points
拓展提升
1. Sure,go ahead.当然可以，请问吧！ahead 意思是向前，这里的go ahead原意为向前走，在这里译作继续问问题，相当于go on
如: — May I start 我可以开始了吗？
— Yes, go ahead. 好，开始吧。
1. So what should we do to prevent it 那么我们该如何防控呢？
prevent 动词，意为“阻止，阻挠”，可与stop互换使用。
prevent sb./ sth. (from) doing sth. =stop .... (from) doing sth. = keep .... from doing sth. (这里的from不能省略)阻止某人/某物做某事
e.g. Lucy's parents tried to prevent her from playing computer games.
= Lucy's parents tried to stop her playing computer games.
露西的父母试图阻止她玩电脑游戏
3.Well, first, we should exercise often to build us up.
首先呢，我们应多锻炼增强自身体质
build sb. up 增强某人的体质，相当于make sb. strong
e.g.: You need to do more exercise to build yourself up.你得多锻炼增强体质。
拓展：warm up 热身
4. Finally, we should keep away from crowded places.
最后，我们要远离人群拥挤的地方
keep away from...=stay away from... 意为“远离.....”，后面接名词、代词或动名词，
e.g.:As students, we should stay away from smoking and drinking.
作为学生，我们应该远离烟酒。
keep...away from... 意为“让...远离...”
e.g.: You’d better keep the child away from the flu.你最好让孩子远离火点。
5. Well, first, ... Second, ... Third, ... Finally, ...first 首先（也可以作为序数词来解释，第一）second 其次（第二）third 然后、以及（第三）finally 最后这是一般来说用于介绍步骤或者表达观点的词,可运用于作文中。
6. 含有must的一般疑问句，肯定回答用must，否定回答不能用mustn’t，而用needn’t或don’t have to。用don’t have to回答时，有人称和数的变化。e.g.: —Must we go there at six
—Yes, you must./ No, you needn't/ don't have to.
—我们必须六点去那里吗？
—是的，必须。/ 不，你不必。
【辨析】must和have to两者都是“必须”的意思
must侧重于个人意志和主观上的必须，have to侧重于客观上的必要；
must可用来表示现在和将来的“必须”，无时态变化，have to则可用于各种时态。e.g.: I know I must study hard. 我知道我必须努力学习。My grandma was ill, so I have to call the doctor in the middle of the night.我奶奶病了，所以我不得不半夜里把医生请过来。
