Today, there is a lot

21、 of pollution. 如今有许多污染。【句析】在there be 句型中, be 后的名词是句子的主语，因而be的数应该与该名词的数保持一致。当后面的名词不止一个时，be的数应该按“就近”原则来确定。【例句】There is some milk in the glass. 杯里有一些牛奶。There are four chairs, a able and a small bed in the room.房间里有四把椅子，一张桌子和一张小床。【考点】there be 与 have (has) 比较：there be 表示“某处存在某人或某物”。have/has 表示“某人拥有某物”。 【

22、例句】I have a pet dog. 我有只宠物狗。There are five pens in the pencil-box. 铅笔盒中有五支钢笔。【注意】当have/has 表示“包括有”或“存在”时，可与there be互换。【考题链接】There is some soup on the table, isnt _?No, I think thats water.A. there B. it C. that D. one答案：A思路分析：there be结构的反意疑问句应用 be there结构。2.

23、a glass for you. 我们应该每天喝水。给你个水杯。【句析】本句中出现了不可数名词water“水”和可数名词glass“水杯”。可数名词：该名词所表示的人或事物可以用数来计量。常见的有： apple, banana, pear 等。不可数名词：该名词所表示的事物不能直接用数来计量。不可数名词前一般不用定冠词the 或不定冠词 a/an 。常见的有：rain雨,tea茶 ,milk 牛奶,water 水等。【例句】There is some tea in the glass. 杯子里有一些茶。【注意】1. 不可数名词前不能直接加数词或a(n)。如：a meat (错)， two te

24、a (错)。2. 不可数名词无单复数变化，谓语动词一般用单数形式。3. 不可数名词可以用much, a little, a bit, some, any, a lot of 等来修饰。4. 表示具体的数量时，常用下面的句式结构：“基数词+ 单位名词+ of +名词”。a piece of paper 一张纸 three glasses of milk 三杯牛奶【考题链接】Some food on the table _ bad.A. goes B. go C. to go D. going答案：A思路分析：food为不可数名词，谓语动词用单数形式。3. It is important for

25、us to protect the Earth for our future.为了我们的未来，保护地球对于我们来说是很重要的。【句析】此句中it 为形式主语，不定式 to protect the Earth for our future 为真正的主语。【例句】Its useful for you to learn how to use the computer. 学计算机对你很有用。【拓展】It + be + adj. + for sb. to do sth. 表示“做某事对某人来说是的”。这一句型中形容词与for后的人物有主表关系，形容词仅仅是描述事物，不是对不定式行为者的品格进行评价。It

26、 + be + adj. + of sb. to do sth. 表示“某人做某事是的”。这一句型中形容词与of后的人物没有主表关系，形容词描述不定式行为者的性格、品质等。【例句】It is kind of you to come to see me. 你来看望我真好。【考题链接】It is important _ us to learn English well.A. of B. with C. on D. for答案：D思路分析：句中人物“我们”与形容词“重要的”有主表关系，故选D。【即学即练】根据括号中的汉语提示完成句子。 1. _ _(有) a book and two pens on
