it、one、that的用法付与区别.pptVIP

3. that代替前面提到的同名异物中特指的事物，所代替的名词可以是可数名词, 也可以是不可数名词，但其前通常不能有修饰语。如：those都可用来代替上文出现的名词， The doctor in our school is younger than that in their school. (that代替可数名词doctor) 　The weather of this week is worse than that of last week. (that代替不可数名词weather) 　The quality of iron produced in your factory is better than that in their factory. (that代替不可数名词quality) 4. those代替前面提到的同名异物中特指的事物，只能指代复数名词，相当于the ones。如： 　　In China students learn English at school as a foreign language，except for those in Hong Kong，where many people speak English as a first or a second language. (those代替复数名词students) 　　The computers in your office are more expensive than those in our school. (those代替复数名词computers)? 区别 I. it／one ／that三者均可用作代词, 指代前面提到的名词。一般说来, it指代同名同物; one与that则指代同名异物。 I have lost my umbrella; Im looking for it. （该句中it就是指前面的my umbrella） I have lost my umbrella; I think I must buy one. （one在该句中表泛指, 因为my umbrella已经丢了） The umbrella you bought is cheaper than that I bought. （替代词that在该句中特指“the umbrella I bought”, 以区别“the umbrella you bought”） II. one与that虽可用来指代同名异物, 但one为泛指, 相当于a／an＋名词; that为特指, 相当于the ＋名词。所以one所指代的名词的修饰语一般为 a／an ／some ／any; that所指代的名词的修饰语往往是the ／this ／that。 A chair made of steel is stronger than one made of wood. （该句中one可以换成a chair） The water in the cup is hotter than that in the pot. （该句中that可以换成 the water） III. one只能代替可数名词单数, 代替可数名词复数时用ones; that既可以代替不可数名词也可以代替可数名词单数, 代替可数名词复数时用 those。 I like this pen more than that one. （one代替可数名词单数pen） There were a few young people and some older ones in the house. （ones代替可数名词复数people） Marys handwriting is far better than that of Peter. （that代替不可数名词 handwriting） These pictures are more beautiful than those. （those代替可数名词复数 pictures） IV. one既可代替事物, 也可代替人, that只能代替事物而不能代替人。有时可以用the one或the ones代替that或those。 The one ／That on the table is mine. （该句中The one代替事物, 并且也可以用That） He is the teacher, the one who is loved by the students. （该句中the one代替人, 不能用that） He advised the farmers to choose the best seed-heads, the ones ／those that had the
