7.Bobby cannot(can’t) see any cakes in the fridge. 波比看不到冰箱里有蛋糕。
四、语法点(理解)
1.There be句型表示“某处有某物”
(1)其中there is 用于单数名词或不可数名词,如:
There is a pencil case in the school bag. There is some soup/milk /tea/coffee/juice/water/chocolate.
(2)There are用于可数名词的复数,如: There are some desks in the classroom.
(3)There be 句型的就近原则:be动词后面如果跟的是不止一种物品,就根据离它最近的物品选用is或are.
如:There are some pictures and a telephone. There is a telephone and some pictures.
2.There be 句型的否定形式:在be动词的后面加not(is not可以缩写为isn't,are not可以缩写为 aren't)把some 改成any。
例:There is a pencil in the pencil-box.(改为否定句) There isn't a pencil in the pencil-box.
There are some crayons on the desk.(改为否定句) There aren't any crayons on the desk.
3.“some”和“any”都有“一些”的意思.“some”一般用于肯定句,“any”用于否定句和一般疑问句。但在一些表示委婉请求,想得到对方肯定回答的疑问句中,也用“some”.
