1． 重点句型
1. If you do, you'll have a great time. (p73-1c)
【直击考点】
1) 本句含有一个由if 引导的条件状语从句，如果主句为一般将来时，条件状语从句要用一般现在时，而不用一般将来时（主将从现）。
If it doesn't rain tomorrow, we'll go to the park.
【注意】if还可以引导宾语从句，此时可译为“是否”，要注意它和引导条件状语从句时的区别。
I wonder if he will come to my party.
2) have a great time 意为“玩的很开心”，其中great可以用nice, good, wonderful, pleasant等代替，与enjoy oneself, have fun同义，其后若接动词应用-ing形式。
The students have a great time learning English.
—I’ll go to Beijing for my summer holiday.
—Have a good time.
—Thank you, I will.
2. Half the class won't come. (p74-2c)
【直击考点】
1) half意为“一半；半数”。half of后跟名词时，这个名词前若有the, this, my等限定词修饰，这时of可省略。此时谓语动词与half后的主语保持一致。
Half (of) this money is mine.
Half (of) the time you don’t even listen to what I said.
2) half of 后也可接代词，这时of不能省略。
Half of them enjoyed the party last night.
2) half还可以作名词，意为“一半；半”，其复数形式为：halves。
“几个半……”可表达为“数词+名词（可单/可复）+and a half”或“数词+ and a half +名词（复数）”。
three months and a half = three and a half months
2) class在本句中意为“班级里的学生”，是一个集体名词。集体名词表示由若干个体组成的集合体，它可以表达单数意义，也可以表达复数意义，具体情况如下：
①当集体名词强调组成该集体的各个成员时，表示复数意义（但无词形变化，即用其本身表达复数），本句中class就属于此种情况。
All the class are very interested in English.
②当集体名词表示一个单位（即表达一个不可分割的整体时），它表示单数意义，作主语时，谓语动词用第三人称单数形式。
Our class is on the fifth floor.
3. If we ask people to bring food, they'll just bring potato chips and chocolate because they'll be too lazy to cook. (p74-2d)
【直击考点】
1) too...to ...是初中英语中的重点结构之一，其构成形式是：“too + adj./adv. + to +v.”，表示“太……以至于不能……”。
His father was too poor to send him to school.
2) too...to可以和so...that/not...enough to...互换
too...to 太……不能 She is too young to go to school. = she is so young that she can't go to school.= She is not old enough to go to school.
so...that... 如此……以至于……
not...enough to 不够……
3) too...for sb. to... 转换成so...that...时，主句主语与从句主语不一致，从句主语应为for sb.中的sb.，此时还可转换成not+adj./adv. + enough for sb. to...，其中形容词或副词也必须是too...to...结构中形容词或副词的反义词。
4) 如果在too...to...结构中含有not或never等否定词时，则表示肯定。
One is never too old to learn.
English isn't too difficult to learn.
4. If you join the Lions, you’ll become a great soccer player.
【直击考点】
1) join在此句中为及物动词，意为“成为……的一员；参加；加入”。
I've joined the swimming club.
2) 辨析：join, join in与take part in
join, join in与take part in 例句
join表示“加入某一政党、团队、组织或人群等”，如入党、入团、参军，着重强调成为其中的一员。 join the army; join the PartyShe joined the company three months ago.
join in通常指参加某种活动，尤指和某人一起参加活动。 May I join in the game
take part in表示“参加”，着重强调主语参加会议、群众性活动或比赛等。 She took part in the World Championship when she was twelve.

1． 重点语法
if引导的条件状语从句
引导条件状语从句最常用的连词是if，表示在某条件下，某事很可能发生，条件是可能存在的，主句中某种情况发生的概率也是很高的。在if引导的条件状语从句中，if和条件句位置灵活，可直接放在主句后面，若if条件句放句首，从句后面要加逗号，和主句隔开。
If you ask him, he will help you.
If you fail in the exam, you will let him down.
If you have finished the homework, you can go home.
另外，if从句还表示不可实现的条件或根本不可能存在的条件，也就是一种虚拟的条件或假设。从句多用一般过去时或过去完成时，表示对现在或过去相反的一种假设。
If I were you, I would invite him to the party.
I would have arrived much earlier if I had not been caught in the traffic.
注意if条件句的时态搭配：
1．if从句用一般现在时表示将来，主句可以使用一般将来时、含有情态动词的句子或祈使句。
If he runs he'll get there in time.
If the fog gets thicker the plane may/might be diverted.
If it stops snowing we can go out.
If you want to lose weight you must/should eat less bread.
2．if从句用现在进行时，主句用一般将来时
If you are looking for Peter you'll find him upstairs.
3．if从句用现在完成时，主句用一般将来时
If you have finished dinner I'll ask the waiter for the bill.
情态动词should 用法
should这个中学英语课本中出现频率很高的一个词。它用法灵活、含义丰富，一直属于热点。should用来提出建议和忠告，后边加动词原形，否定句直接在should后边加not。一般疑问句要把should提前。
1、通常用来表示现在或将来的责任或义务，表示“应该，应当”。
Crime should be punished.
We should obey the traffic rules.
You shouldn’t smoke in the hospital.
Should I come here tonight
二、可以用来表示有较大可能实现的猜测、推论，表示“可能，按理说应该 (=will probably) ” The headmaster should arrive soon.
They should be home by now, because they have left half an hour.
3、表示“竟然”
It's strange that he should be late.
语法运用
1.If you go to the party, you_________ (have) a great time.
2. It will be a long time before Peter _________ (finish) his work.
3. I will tell her the answer if she _________ (ask) me.
