(D)
You can not see any object unless light from that object gets into your eyes. Some of the things you see give off light of their own. The sun, the stars, a lighted lamp are examples that can be seen by their own light. Such things are luminous. Most of the things you see are not giving off light of their own. They are simply reflecting light that falls on them from the sun or some other luminous bodies. The moon, for example, does not give off any light of its own. It is non-luminous. You see it because sunlight falls on it and some of it reflects in our direction. So moon light is only second hand sunlight.
When you look at a book, it sends to your eyes some of the light which falls on it, and you see the book. If light could be kept out from where you are so that there would be no light for the book to reflect, then you could not see the book even with your eyes wide open.
Light travels so fast that the time in which it travels from the book you are reading to your eyes is so short as if there were no time at all. Light reaches us from the moon, which is about 380 000 kilometers away, in only a little more than a second.

A. Decide to Be Happy B. Lower Your Expectations C. Learn to Enjoy the Moment D. Look for the Good in Everything E. Let People Deal with Their Own Problems F. Focus More on What You Can Control Than on What You Can’t |
So many times I hear people say that they will be happy once a certain event occurs. They think that once they move into a new house, start their new job, travel or retire they will be happy. But it doesn’t work that way.
If you truly want to be happy, here’s what to do.

You are not just a victim of circumstances or your emotions. Think about it this way. If you are in a horrible argument with someone, and the person you most respect enters the room, what will happen? The fighting will likely stop immediately, your mood will change, and so will your behavior. You do have control, and you are the one who decides how you will face the day!
2 |

We are never disappointed unless we have expectations. If you base your emotions on the need for certain things to happen, you will likely be let down most of the time. Instead, work hard, and treat everything good that happens as a bonus for which you can be thankful.

Don’t get too wrapped up in issues involving friends or family. We are each responsible for our own lives, and even when someone makes a bad mistake, it is not up to you to make things better. And remember that worry doesn’t help anyone!

You might not be satisfied with your income, but there’s no point complaining about it. Improve your diploma so that you can get a better job in the future. You may have an incurable illness, such as diabetes, but the fact that it’s incurable doesn’t mean that it cannot be managed.

You don’t have to be a Pollyanna(盲目乐观者)about life, but you can see the bright side of almost every situation if you just make a point of looking for it. Happiness is not an uncatchable mouse! Once you have made up your mind that you are going to be happy despite what is going on around you, the task becomes easier. One of the key things to remember is that happiness doesn’t come from outside but begins on the inside and actually spread outward, and can influence everyone around you in a positive manner.

Our lives were supposed to be more flexible and familyfriendly thanks to the technology at our fingertips. But in this age of BlackBerrys, recession pressures, working at home after hours and on weekends, family time may not be working out the way we thought.
Busy parents who expected more time with the kids are finding that more work hours at home don't necessarily translate into quality time with them.
A new generation of parents need to discover the meaning of “quality time”, researchers say. “Personally, just given the life I lead, I think there is something to this idea of quality time—spending productive time with children vs. just being around,” says Peter Brandon, a professor at Carleton College. He says engaging or interacting with a child in activities such as reading or playing counts as quality time rather than “passive monitoring”, such as washing the dishes while the child is watching TV.
“This_time_with_children_pays_off,” Brandon says. He notes that good parentchild relationships result in children being happier and more successful, including at school.
As parents struggle to be more available to their kids, new research on work and family schedules to be presented Friday at the meeting in Dallas includes a study that shows parents' availability is on the decline because more parents are in the workforce. Although parents today may be spending more time on child care, they are less available overall.
Working parents who spend less time with their children should try to make sure the time they do spend is communicating with them, vs. doing the dishes or spending more time on themselves, Brandon says “The tradeoff is not necessarily taking away time from your kid,” he says, “You're taking away time from other things.”
20.The first paragraph mainly intends to tell us that ________.
A.technology lets parents work at home

A.some families are not experiencing quality time
B.it's enough for parents to stay with their children

D.working hours at home can transform into quality time
22.According to Brandon, the quality time means ________.
A.just being around with children
B.work time is separate from family time
C.spending interactive time with children
D.letting the children do whatever they want to do
23.The underlined sentence “This time with children pays off” means________.
A.the time with children is of little value
B.the time with children costs quite a lot
C.the time with children leads to good result
D.the time with children has a bad effect on them
24.What will the author most probably talk about in the next part of the passage?
A.How to spend more time at home.
B.How to do the dishes in a proper way.
C.How to spend more time in working at home.
D.How to take away time in a much proper way.
