(她走了。)从这句话中动词所用的现在完成时态可以看出“走”的动作是过去发生的，而对现在所造成的结果是她不在这里了。He speaks French so fluently. He learned it in Paris. He was there for two years.He has studied French.
(他学过法语。)这句话所说明的结果是他现在懂法语。Look! The blackboard is so clean now. He has cleaned the blackboard.
(他已经擦过黑板了。)?这句话所表示的结果是黑板现在是干净的。定义2：现在完成时态还表示动作或状态从过去开始一直延续到现在甚至将来。Mike borrowed the books two days ago.Mike has kept the books for two days.二、现在完成时的构成 1. 现在完成时的肯定句句型 主语（第一、二人称单、复数)+have 主语（第三人称复数） +have +过去分词 主语（第三人称单数） +has We have lived in Beijing.

I haven’t seen the film yet.2 I have done my homework already.I haven’t done my homework yet.3. Mother has just cleaned the house.Mother hasn’t cleaned the house yet.1 I have seen the film already. 标志词（2）：这种用法还可与 for +一段时间, since+过去的时间点, these years, so far, in the past/last …years等连用1.We __________ (learn) English for three years/ since two years ago/since 2000.

Changes to my hometown Great changes have taken place in my hometown over the years. In the past, the environment here was natural and beautiful. The rivers and lakes were clean and the air was fresh. People went to work on foot or by bike. They lived in small, old houses.
Now the small village has turned into a modern town. You can see many tall buildings and new roads in the town. People go to work by bus, taxi or car. Many people have moved into large, new flats.
I hope my hometown will become more and more beautiful in the future.Bye-bye!
