音标的用法及题型
1)Teachers always tell us to try to be()honest student today and()useful man tomorrow.A a,an B an,a
C an,an
D a a 解析:B两个空为泛指,honest以元音音素开头,因此用定冠词an。Useful的音标以辅音音素{ju}开头,则用a 2)Lucy is()university student,she likes playing()piano A a,/ B a,the Can the
D an,/ 解析;B university的首字母u是元音字母,但是其音标的首音节{ju}是辅音,所以其面前要用定冠词the
三、Some,和any的用法
Some用于肯定句中,any用于否定句中和一般疑问句中。
但要注意:在表示请求的would you like的问句中用some,如 would you like some tea?
四,所有的肉类都是不可数名词,如:beef,fish、pork、duck、chicken等,但是:{fish当“鱼”讲时,为可数名词;而当“鱼肉”讲时,为不可数名词。Chicken当“鸡”讲时,为可数名词,当“鸡肉”讲时,为不可数名词。

D are

b:also:用于肯定句句中。He also went there on foot.c:either:用于否定句句末。My sister does not like this song,either。
六、球类前面不能加定冠词the,乐器前面可以加定冠词the,如:play football/basketball。Play the piano/guite
七、回答几年级几班的表达方式为先说班级后说年级且首字母要大写,如:七年级六班Cla Six Garde Seven 八,复合不定代词是由some-,any-,no-,every-加上-one,-body,-thing,-where,-time所组成的不定代词。复合不定代词包括:someone(某人)somebody(某人)something(某事物)somewhere(某地)anyone(任何人)anybody(任何人)anything(任何事物)anywhere(任何地方)no one(没人)nobody(没人)nothing(没事物)nowhere(没有地方)everyone(每个人)everybody(每个人)everything(一切事物)everywhere(一切地方)等。这些复合代词具有名词性质,在句中可用作主语、宾语或表语。
1)不定代词做主语,谓语动词用单数。如Everything is ready,isn’t it? 2)形容词修饰不定代词时要后置,I have something interesting to tell you.九,lots of 和 a lot of ,a lot ,too much ,too many的区别(1)lots of和a lot of可以当做定语,即当做many或much(或者是too many,too much)那样来使用。因此,谓语动词的数不是依据lot和lots来决定,而是依据of所引导的名词来决定,如:
(2)a lot of=lots of表示”许多的“,可以修饰可数名词复数和不可数名词。
A lot of time has been wasted.有许多时间给浪费掉了。(a lot of=much/too much There are lots of books in the library.在图书馆里有好多书。(a lot of=many/too many(3)a lot是表示程度的一个短语,意为”很,非常“。如:thanks a lot(多谢)

few,a few,little,a little 虽然都表示“少”,但

十一、arrive是不及物动词,表示到达、抵达某地(尤指行程的终点),后常接介词at或in,一般in接大地方,at接小地方,若是地点副词(home,here,there),则不需用介词。例如:
