Now I can search for a lot of things about it.Good! You can also find out about countries in the world.OK! Let’s try it now!1. He could do a lot of things with this computer. 他可以用他的电脑做许多事情。 a lot of 意为“许多,大量的”, a lot of 可以用 lots of 进行替换。 a lot of 与 lots of 既可以修饰可数名词也可以修饰不可数名词,常用于肯定句中。【拓展】 a lot 可用作名词短语,表示“很多;多量” , 也可作副词短语,修饰动词,意为“十分、 非常”,相当于 very much 。2. You can also find out about countries in the world. 你还可以查找有关世界各国的信息。 can 既可以表示“可以;可能;请求;猜测;允许”,也可表示能力,意为“能;会”。 can 是情态动词,后面只能跟动词原形,没有人称和数的变化。find out 意为“发现;查明(真相等)”。【辨析】 look for, find 与 find outlook for 意为“寻找”,强调寻找的过程;find 强调寻找的结果;find out 通常表示“弄明白,搞清楚,查明 ( 真相等 )” , 指经过一番努力才找到。3. Let’s try it now! 现在咱们来试一试吧!此句是由 let 引导的祈使句。句型结构为: Let’s + 动词原形 + 其他。意为“咱们……(吧)。”表示建议某人做某事,其中 let’s 是 let us 的缩写形式,后接动词原形。Let’s Learnemail my friends给我的朋友发电子邮件send greetings向……问好search for a lot of things查找许多东西find out about countries找到有关各国的信息Let’s PractiseWe canemail our friends.send greetings to our friends.What can...
