This is a computer.?这是一台电脑。（在近处）? That is a bike.?那是一辆自行车。（在远处）? 2.在回答“this”和“that”作主语的疑问句时，常用“it”代替“this”和“that”。如：? －Is this/that a car??这/那是一辆小汽车吗？? －Yes, it is./No, it isn′t.?是的，它是。/不，它不是。? －What′s this/that??这/那是什么？? －It′s a ruler.?这/那是一把尺子。? 3.陈述在一起的两样东西时，应先说“this”，后说“that”。如：? This is a book. That is a pen.?这是一本书，那是一枝钢笔。?4.one与it的区别?one指代上文提到过的同类事物中的一个，但不是上文提到的那一个事物。如果指同类事物中的一些，要用ones。如：?This apple is small. Please give me a big one.?这个苹果小，请给我一个大的。?These books are mine. Those ones are Lily's.?这些书是我的，那些书是莉莉的。?it指代前文中提到过的那一个事物。如：?My bike is very old,but I like it very much.?我的自行车很旧，但我很喜欢它。?Where is my new pen? I can't find it.?我的新钢笔在哪儿？我找不到它了。 1.I’m ___ Chinese student(学生), and Jim is _____ English student. A. a;a B.an; a C.a;an D.an;an 2.This is ___ orange orange and that is __ green orange.
