教材分析
本单元是环绕first aid, safety in the home,打开论题。对话课中描绘两个学生在街上看到一个女孩从自行车上摔下来的经过，一起对话中运用了神态动词的用法，课文中附有图像和口语操练，协助学生晓得急救的重要性及有关的常识。
要点难点:
1. what should you do if a person has drunk poison by mistake? 假定有人误喝了毒药，你怎么办？
by mistake是固定词组，意为“差错地”，“无心肠（做错完事）”。例如:
she put salt in her cup of coffee by mistake．她错将盐放入咖啡里了。
2. do with，deal with
二者都可以用来标明“处置”的意思
可是用于特别疑问句的时分do with与what连用；deal with则与how连用。例如:你会怎样处置一个从自行车上颠仆而严峻受伤的？
另外，do with还可表达另外意思。例如:
what did you do with my umbrella? (=where did you put my umbrella?)

语法:神态动词（modal verbs）
1） must
a.标明必需要干的事。如:
we must obey the rules．咱们有必要恪守规则。
you mustn’t talk like that．你可不能那样说话。
must也可以表达曩昔情况，首要用于直接引语中。
she said that we must wait a little while．她说咱们必需要等一会儿。
b．标明一种估测（只用于必定句中，口气比may要必定得多）。
must have则标明对曩昔情况的估测。例如:
this must be tom’s room. 这准是tom的房间。
jack must have gone there, hasn’t he? / didn’t he?杰克准是去过那儿了，对不对？
c．比照:have to也标明“有必要”，但have to更偏重客观需要，must偏重阐明片面观点。如:
we had to be there at 10 o’clock．咱们得在10点到那儿。（客观需要）
we must be back before 10 o’clock．咱们有必要10点前回来。（片面认为）
有时也可交换:
we must / have to leave now．咱们得走了。
must和have to的否定式即mustn’t和don’t have to意思完全不一样。mustn’t标明“不作某事”，有阻止的意义；don’t have to标明“不必要（作某事）”，富含“客观上无此必要”的意思。例如:
you mustn’t move someone if the person is badly hurt．假定这人受了重伤，你必定不要动他．
the person isn’t hurt at all. you don’t have to give him first aid．这自个根柢就没有受伤，你不必给他进行急救。
2）need need作及物动词，和不定式连用:
need to do sth. 需要干某事
need也可做神态动词，首要用于否定句，即:
needn’t + v.不必干某事 例如:
you need to tell him the reason．你需要告诉他缘由。
you needn’t tell him the reason. 你不必告诉他缘由。
神态动词need也可用于疑问句，必定答复对一般must，否定答复时用needn’t．
——need i come？ ——yes，you must．／no，you needn’t．
