一,下列各有一个错误,请找出来并改正.
1.what language can mary say?
应该有2个错误吧..自我感觉的..还有,mary为什么不加S?
二.按要求进行句型转换.
1.my penpal's name's Alice.对划线部分提问,划线部分：Alice
（ ）your penpal's （ ）
三,完形填空
1.He is staying here ( ) a week.
A.at B.in C.for D.of
是D?
2.we are going to visit ( ) places of interest.
A.much B.few C.little D.many.
这一题,
附加：
what与what's怎么用?
如 what your penpal's name
还是 what's your penpal's name?
go to和go to go ,有什么区别?怎么用?
at,in,on的用法...
6.Mr.Green ( ) his friend to us
掉了一题...
这是首字母填空，首字母是i

一 mary 应该大写,这是人名 Mary ,还有一处错误是say 要改成speak.say+ 说话的内容,
speak+语言.如：Can you speak English?I said you were wrong
二 What is =What's .name
三 1 C for+一段时间
2 D 此题是问many ,much ,few ,little 的异同.many/much 表许多,many+可数名词,
much+不可数名词；lew/little 都表否定,“几乎没有,很少”的意思.few+可数名词,
little+不可数名词.
四 What's you penpal's name?这才是正确的.前面的what's =what is,后面的penpal's 名词
所有格,不是is.
五 go to +some place 去某地 Let's go to school.
go to +do sth 去做某事 Let's go to see a film
go to go 是go to do 的用法,不过动词是go 而已.
六 at+时刻 如：at 8:05,at twelve o'clock,at half past six
on+ 具体某一天 如：on Monday,on May 5th,
in +比一天大的单位 如：in a week ,in two months,in three years,in spring
in+一段时间 如：in five hours,in two minutes
