二、单元重难点知识讲解
1．—How many tins of dog food can we buy with that?
—None, Eddie.
[译文]—一我们用那些钱能买多少听狗食?
—一听也买不成,埃迪.
with在这里是“用”的意思.
e.g.We see with our eyes.
我们用眼睛看.
You can cut it with a knife.
我们可用刀把它切开.
He hit it with a hammer.
他用锤子砸.
none作代词,表示“没有任何人、物”,这里none是we can buy none的省略说法.
e.g.None came on time.
没有人准时来.
I know none of you.
我对你一无所知.
—Is there any food in the fridge?
冰箱有什么食物吗?
—None.
没有任何食物.
2．Maybe we can order a pizza…
[译文]也许我们能订个比萨饼……
maybe意思是“或许”,用来表示不确定的猜测.它是副词.
e.g.—Will he come tomorrow?
—Maybe, but I’m not sure.
—明天他会来吗?
—或许会,但我不确定.
Maybe it is fine tomorrow, maybe it isn’t.
也许明天是晴天,也许不是.
注意maybe与may be的区分.maybe是副词,而may be是情态动词后接动词原型.意思是“可能是”“也许是”.
e.g.This coat may be Peter’s.
这件大衣可能是彼得的.
That may not be true.
那可能不是实情.
order在这里是“订购”的意思,还可以表“点（酒、菜）等”.
e.g.I’d like to order a fish, please.
我想点条鱼.
I’ve ordered a steak.
我要了一份牛排.

3．There is less air pollution in Sunshine Town than in other areas of Beijing.
[译文]在阳光镇空气污染要比北京其他地区少.
句中less是little的比较级形式,与more意思相反.
e.g.There are more people in Hongkong than in Nanjing but there is less land in Hongkong than in Nanjing.
香港人口比南京多,但土地比南京少.
It rains less in the north than in the south.

4．They do not have to go far if they need help with their homework!
[译文]如果他们做作业需要帮助,就不必跑得很远了.
have to意思是“必须,不得不”.
e.g.We have to do too much homework every day.
每天我们不得不做太多的作业.
I have to be at my office everyday.
我每天必须待在我的办公室.
not have to表示needn’t,意思是“不必”.
e.g.We have plenty of time to get there. You don’t have to walk so fast.
我们有足够的时间去那里.你没必要走这么快.
You don’t have to finish this exercise before class, because the teacher asked us to hand it in tomorrow.
你没有必要上课前完成这次作业.老师要求我们明天交.
注意：must与have to的区别,两个词意思相近,都表示“必须”的意思,但在含义仍有区别：must表示说话人的义务或说话人主观认为“必须,应当”做某事；have to表示由于某种外界原因而“必须,不得不”作某事.即must侧重说明主观看法,have to强调客观需要.
e.g.I must go to the bank to get some money.

8．If you don’t like Chinese food, there are lots of Western restaurants too!
[译文]如果你不喜欢中国的食物,这儿也有许多西式餐馆.
lots of是“许多的”的意思,亦可说a lot of,它既修饰可数名词复数,也可修饰不可数名词.
e.g.There are lots of good shops in Sunshine Town.
在阳光镇有许多好商场.
I haven’t got a lot of time to do it.

9．You pay a little money and they are yours.

pay是“花费,支付”的意思,经常构成短语“pay money for something”意思为“买……花钱多少”.
e.g.I pay ten dollars for the book.

a little是“一点儿”的意思,修饰不可数名词.
e.g.There is only a little water in the bottle.
瓶子里只有一点儿水.
a little milk/ sugar/ tea… 少许牛奶、糖、茶……
注意a little与little的区别：两词均修饰不可数名词,a little是“有一点儿”的意思,“little”是“几乎没有”的意思.a little带有肯定语气,而little带有否定语气.
e.g.I have little time for reading.
我没有多少时间看书.
三．语法点拨：
1．How much与How many的用法；
2．正确运用名词所有格’s的表达方式.
（1）学会用How many和How much谈论数量.
当我们问数量是多少时,就用How many和How much来提问,但要注意How many用来提问可数名词的多少,而How much是用来提问不可数名词的多少.如下表所示.
How much
Beijing Duck can you eat?

How many
restaurants are there in Sunshine Town?

e.g.How many pencils do you have?
你有多少支铅笔?
How much milk do you drink every day?
你每天喝多少牛奶?
How much money do they have?
他们有多少钱?
How many floors do the buildings in Sunshine Town usually have?
阳光镇的建筑通常有多少层楼?
（2）正确运用名词所有格’s的表达方式
在英语里,表示某个物体属于某个人,我们可以用’s来表示,即“……人的”的意思.但要注意,如果名词是单数的,就加’s,如果名词是复数的,但结尾的字母不是s,则加’s,若结尾的字母是s,则只需加’就行.
e.g.Millie’s home Millie的家
Kitty’s pencil Kitty的铅笔
Daniel’s calender Daniel的日历
teachers’ office 教师办公室
students’ bedroom 学生们的卧室
children’s presents 孩子们的礼物
men’s cap 男式帽子
women’s gloves 女式手套
people’s right 人民的权利

给你U2的短语1.welcme to sunshine town 2.a tin of dog food ^^^等等
