Notice also the difference between the following two sentences:
Mr Brown lived in Hong Kong for ten years. (past simple)
Mr Brown has lived in Hong Kong for ten years. (present perfect)
The first sentence indicates that Mr Brown is not living in Hong Kong now; the second one indicates that Mr Brown still lives in Hong Kong at the moment of speaking. (although we are not told whether he will continue to live in Hong Kong or not).
6. The present perfect continuous is used for activities that began in the past, continued up to the present moment and may (or may not) extend into the future(指過去開始、今天繼續、將來或許延續的事情).
e.g. Where have you been? We've been waiting here for hours.
I have been learning English for ten years (and intend to continue learning it).
NOTE: There is little difference in meaning between Mr Brown has lived in Hong Kong since 1970 and Mr Brown has been living in Hong Kong since 1970; but with certain verbs there is a difference in meaning.
e.g. I've been reading The Old Man and the Sea (but I haven't finished it).
I 've read The Old Man and the Sea: I finished it yesterday.

Who's been eating my cake? (i.e. there is some left)
7. The past perfect and past perfect continuous are used

e.g. After the dentist had pulled out my bad tooth, I felt much better.
When we arrived at the station, the train had left.
A fault was discovered in the engine when the ship had been sailing for a few hours.
By 1975, Mr Brown had been living in Hong Kong for five years.

8. The future simple is used for future events or activities(將來的事情或活動).

Mr Chan will go to Japan on Business next week.
9. The future continuous is used
(a) for activities or states that will extend over a period of time in the future(某些延續將來一段時間的事情).
e.g. The train will be passing through the tunnel in about five minutes.
I wonder what we shall be doing tomorrow night.
(b) for a future event that will take place as a matter of course, and the use of this construction avoids giving the impression of volition, insistence, etc(將來因必須性以顯示其不甘及執意的事情).
e.g. Now that we work in the same office we shall be seeing each other a lot.
When will you be coming to Hong Kong?
NOTE: I will write to you soon shows stronger volition or commitment than I will be writing to you soon. The same principle applies to we shall see each other a lot and we shall be seeing each other a lot.
Similarly, the question When will you come to Hong Kong? indicates stronger insistence than When will you be coming to Hong Kong?
10. The future perfect and future perfect continuous are used
(a) for a future event that will take place before some other future event(未來兩樁事情中,其中較早發生的一件事).
e.g. He will have left by the time you get there.
By the end of this school year, I shall have been attending this school for five years.
11. Future in the past (i.e. future time as seen from the past) can be expressed by
(a) the use of would.
e.g. She decided at that time she would never see her boyfriend again.
I thought he would recover, but the poor man died after all.
(b) the use of was (or were) going to. (Such a construction also indicates unfulfilled intention.表示一樁仍未達成願望的事情)
e.g. You were going to say something to me a minute ago, weren't you?
I was going to leave the house when it started to rain.
12. There are some verbs which are not often used in the continuous tenses. Some of these verbs are: believe(相信), belong to(屬於), compare(比較), consist of(包括), contain(包含), cost(價值), depend on(依靠), desire(渴望), differ from(不同), dislike(討厭), exist(存在), forget(忘記), hate(憎惡), interest(興趣), know(知道) , like(喜歡), love(愛慕), matter(困擾), measure(量度), own(擁有), remember(記住), seem(似乎), think(想到), understand(明白), want(要).
e.g. This beautiful villa belongs to a very rich man.
He seems to know the answer.
I believe you are right.
Do you remember seeing him before?
I think it's going to rain.
13. The simple past is used to show imaginary or unreal situations in the present (在現在的情況下一些想像或虛假的事情)and the past perfect is used for similar situations in the past(在過去的情況下一些想像或虛假的事情).
e.g. I wish John were here now. (But he is not.)
Some women wish they had been born men.
"Children, it is time you went to bed." (But they are not in bed.)
If I were a king, I would make you my queen.
We would have caught the train if we had started earlier.
She looks as if she had seen a ghost.

Dear Madam Wise,
I (go) 1 steady with a man for seven years and we are planning (engage) 2 to get married. But there is one problem: he seems (care) 3 more for his mother than for me.
He always says his mother takes very good care of him. (be) 4 a career woman myself, I can't possible devote as much attention to him as his mother (do) 5 . He also says getting married means (have) 6 to pay more taxes. I wouldn't put up with him if I (not love) 7 him so much.
I enjoy (go) 8 to the movies but he would rather stay at home (watch) 9 TV with his mother. He is so attached to his mother that he even insists on her (come) 10 to live with us after our marriage.
Now I (catch) 11 in the dilenma of either (leave) 12 him or marrying him and becoming a neglected and frustrated wife. I (approach) 13 30. It would be rather late to start another romantic affair, even if I (feel) 14 inclined to do so.
What would you do if you (be) 15 me?
Yours sincerely,

For some reason Michael (suffer) 56 from insomnia recently. One night he (decide) 57 to go to bed much earlier than usual. At 9:30 he (lie) 58 down in bed, closed his eyes and began to count sheep, (hope) 59 that he (fall) 60 asleep very soon. However, thinking of those furry little animals (jump) 61 over fences only made him (feel) 62 more restless, so he (stop) 63 , went to his bookshelf and (take) 64 out the most boring book he had. It (call) 65 Buddhism in Japan. At the end of an hour he (still read) 66 . In fact, he (become) 67 quite interested in the subject. He (lay) 68 down the book and tried another method.

Half an hour later the lump of mud (still murmur) 72 the words. Indeed, Michael felt so heavy that he could hardly breathe. In desperation he gave up (try) 73 to be a lump of mud and (swallow) 74 a sleeping pill, but it had no effect on him whatsoever.
At 3 o'clock he got up and (walk) 75 round and round his room until he (grow) 76 dizzy. At 4 he went back to his bed and gazed abstractedly into space. Gradually his eyes began to feel heavy and, finally, he fell into a troubled sleep.
He (awake) 77 the next morning only (find) 78 that it (be) 79 already a quarter to nine, which meant another mad morning rush to get to work. When he arrived at the office, his boss (already stand) 80 beside his desk, (eye) 81 him severely. "(Look) 82 here, Mic," he said, "this is the sixth time you (be) 83 late this month.
