听力原文：F: Paul, nice to see you back from the university. How do you like your new university？ I remember your mom had wanted you to go to London University so that you can live at home and walk or cycle to attend the lectures.
M: Well, you know I didn't go to London University after all. My new university is on the suburbs of an ancient cathedral city and it is almost 8 miles from the city center. The university is planned on the so called American campus system. That is to say, students live in halls of residence grouped around the main university buildings.
F: You mean you live, eat and study within the university proper？
M: Yes, I like it. Because we are a real community. We've got comfortable common rooms and bars. We arrange dances and parties. We've got clubs, theater groups, choirs and so on. And we've got an orchestra. I played the drums in it. By the way, how about your university days, Betty？
F: I rented a house with two other girls in the middle of the city about ten minutes walk from the university. The house is falling to pieces. It is damp and there is no proper heating. M: That sounds awful. I couldn't work in a place like yours. The district is poor and could almost be classed as a slum.
F: I don't think so. We live among real people who treat us as real people. We've got an electrician living next door, who is always coming in and mending our cooker and electric fires. We could try to get into one of the halls of the residents. But we prefer to be independent. It's nice to belong to the city and to do things outside the university.
M: What sort of things do you do outside the university？
M: Well, there is a group of us who go and help in a home for handicapped children. And I sing in the city bar "Choir". We get on well with the local people, not like you in that suburban district.
W: Well, I like history. And my university is one of the best universities for that subject. Besides, it is an ancient city with a lot of historical relics and sightseeing spots. If you can drop by by any chance, I can show you around.
F: You bet.

It happens to all of us sometimes, doesn’t it？ You have a deadline to meet，but instead of doing your work, you check Facebook or do some on line shopping.This is called procrastination, and it affects everyone.So how can you stop procrastinating？
We often procrastinate because a task seems too big, or impossible to achieve.Try breaking down the task into smaller pieces.For example, instead of thinking，“I need to finish this essay by 10 p.m.tonight ” tell yourself,“I’ m going to make a short outline, fill that in, and then look for quotes.”
Another important factor is your environment, isn’t it？ If there are too many distractions in your work space, you may be tempted to procrastinate more.Are there any things in your work space (for example, a TV) that could be causing you to lose focus？
Making a timeline with goals and deadlines is a great way to stop yourself from procrastinating.
However, it is important to make your deadlines realistic so that you can be sure you’ll stick to them.
Some people like to wait for the perfect time to start a task, while the perfect time is often now.Try something called the Two-Minute Rule to help you get started.This idea comes from David Allen’ s best-selling book, Getting Things Done.It states that.if something takes less than two minutes， such as washing your dishes after a meal, then you should do it now.
1.Procrastination means().
A.putting your work off till later
B.doing your work quickly
C.doing your work carefully
D.doing your work well
2.Sometimes we procrastinate because a task seems too().
A.easy
B.small
C.fun
D.big
3.Having a TV in your work space is an example of an environmental().
A.distraction
B.reaction
C.attration
D.concentration
4.Setting realistic is a() good way to stop procrastinating.
A.environments
B.deadlines
C.focus
D.places
5.The Two-Minute Rule states that if something takes no more than two minutes, you should().

B.do it later
C.do it now

If you want to teach your children how to say sorry, you must be good at saying it yourself, especially to your own children. But how you say it can be quite tricky.
If you say to your children "I'm sorry I got angry with you, but...", what follows that "but" can render the apology ineffective: "I had a bad day" or "your noise was giving me a headache" leaves the person who has been injured feeling that he should be apologizing for his bad behavior. in expecting an apology.
Another method by which people appear to apologize without actually doing so is to say "I'm sorry you're upset"; this suggests that you are somehow at fault for allowing yourself to get upset by what the other person has done.
Then there is the general, all covering apology, which avoids the necessity of identifying a specific act that was particularly hurtful or insulting, and which the person who is apologizing should promise never to do again. Saying "I'm useless as a parent" does not commit a person lo any specific improvement.
These pseudo-apologies are used by people who believe saying sorry shows weakness. Parents who wish to teach their children to apologize should see it as a sign of strength, and therefore not resort to these pseudo-apologies.
But even when presented with examples of genuine contrition, children still need help to become aware of the complexities of saying sorry. A three-year-old might need help in understanding that other children feel pain just as he does, and that hitting a playmate over the head with a heavy toy requires an apology. A six-year-old might need reminding that spoiling other children's expectations can require an apology. A twelve-year-old might need to be shown that raiding the biscuit tin without asking permission is acceptable, but that borrowing a parent's clothes without permission is not.
If a mother adds "but" to an apology, ______.
A．she doesn't feel that she should have apologized
B．she does not realize that the child has been hurt
C．the child may find the apology easier to accept
D．the child may feel that he owes her an apology
