Early rising makes people able to plan the work for the day. We can’t work well without a good plan. Just as the plan for the year should be made in the spring, the plan for a day should be made in the morning. Early rising gives us enough time to get ready for our work, such as to wash our hands and eat our breakfast. So the popular saying says, “Early to bed and early to rise makes a man healthy, wealthy and wise.”

One bag, that’s it.

The importance of packing light cannot be overemphasized(过度强调). Limit yourself to 20 pounds in a carry-on bag. A 9’× 22’ ×14’ bag fits under most airplane seats. And after you enjoy that sweet mobility and freedom, you’ll never go any other way.

You’ll walk with your luggage(行李) more than you think you will. Before leaving home, give yourself a test. Pack up completely, and practice being a tourist for an hour. Fully loaded, you should enjoy window-shopping. If you can’t, go home and thin things out.

Packing light isn’t just about the trip over and back—it’s about your traveling lifestyle. Too much luggage marks you as a typical tourist. It slams the back door shut. Changing locations becomes an important operation. With only one bag, you’re mobile and in control. Take this piece of advice seriously. Pack light, and pack smart. These days, you can’t bring anything possibly dangerous—such as knives, lighters or large amounts of liquid (液体)—in your bag.

What to bring?

How do you fit a whole trip’s worth of luggage into a small backpack or suitcase(衣箱)? The answer is simple: bring very little.

Bring out everything you think you might need on the floor. Pick up one item(件) at a time and check it. Ask yourself—not “Will I use it?”, but—“Will I use it enough to feel good about carrying it all the way? The world is getting really small—you can buy Colgate toothpaste, Nivea cream and Gillette razors in almost every country.

Think about what you can do without—not what will be convenient on your trip. When in doubt, leave it out.

1.What do the last two paragraphs mainly talk about?

A. Packing light is a kind of travelling lifestyle.

B. Packing light can give you mobility and freedom.

C. How to find out what to take and what not to take on a trip.

D. How to find out if your luggage is too heavy.

2.You are allowed to take _______with you when you travel according to the passage.

A. Colgate toothpaste     B. Lighters    C. Knives     D. a great deal of liquid

3.The underlined part “thin things out” possibly means________.

A. make things thin to bring

B. make your luggage lighter

C. take out dangerous things

D. throw useless things away

4.The author seems to believe that _________.

A. people had better bring nothing when they travel

B. people can use Nivea cream only in their home town

C. the importance of packing light is overemphasized now

D. you will be easily seen as a tourist with a lot of luggage

5.What is the best title for the passage?

A. Dying for a trip

B. Things to take on a trip

C. Pack light and pack right

D. Travelling: a typical way of life

When we can see well, we do not think about our eyes often: It is only when we cannot see perfectly that we come to see how important our eyes are.

People who are nearsighted（近视的） can only see things that are very close to their eyes. Many people who do a lot of close work, such as writing and reading, become nearsighted. Then they have to wear glasses in order to see distant things clearly.

People who are farsighted face just the opposite problem. They can see things that are far away, but they have difficulty reading a book if they don't hold it at arm's length. If they want to do much reading, they must get glasses too.

Other people do not see clearly because their eyes are not exactly the right shape. This, too, can be corrected by glasses. Some people's eyes become cloudy because of cataracts (白内障). Long ago these people often became blind. Now, however, it is possible to operate on the cataracts and remove them.

When night falls, colors become fainter（更模糊） to the eyes and finally disappear. After your eyes have grown used to the dark, you can see better if you use the side of your eyes rather than the centers. Sometimes, after dark, you see a small thing to one side of you. It seems to disappear if you turn your head in its direction. This is because when you turn your head, you are looking at the thing too directly. Men on guard duty sometimes think they see something moving to one side of them. When they turn to look straight at it, they cannot see it anymore, and they believe they were mistaken. However, this mistake happens because the center of the eye, which is very sensitive (敏感的) in daylight, is not as sensitive as the sides of the eye after dark,

1.According to the passage, a _______ is more likely to be nearsighted.

A. guard                B. doctor                 C. writer                  D. painter

2.People who are farsighted _______.

A. cannot do a lot of close work without glasses

B. can only see things that are very close to their eyes

C. have the same problem as the nearsighted people

D. have difficulty reading a book if they hold it at arm's length

3.To see a small thing at night, we need to look _______.

A. with wide open eyes                             B. with half shut eyes

C. straight at it                                             D. in a slightly different direction

Because earthquakes happen without warning, it’s important to take steps now to prepare. Because you don’t know where you will be when an earthquake happens, prepare some supplies(急需品) for your home, work place, and car.

1．Water

A person needs at least 1/2 gallon(加仑，容量单位) of water daily just for drinking. Store at least 1 gallon of water per(每一个) person per day and be prepared for a 72 hour period. It is suggested that you buy bottled water. Keep bottled water in its original container(容器) and do not open it until you need to use it. Also, do check the “use by” date.

2．Food

It’s always a practical idea to keep a supply of non perishable(不易腐烂的) food on hand. Have an enough supply of canned(灌装的) food, powdered milk(奶粉), dried fruits, non salted nuts and canned juices for at least 72 hours.

3．Flashlights(手电筒) and spare batteries(备用电池)

Keep a flashlight beside your bed, at your place of work, and in your car. Do not use matches or candles after an earthquake until you are sure that no gas leaks(泄漏).

Prepare a battery powered(装电池的) radio and spare batteries. Most telephones will be out of order(发生故障), so radios will be your best source of information.

4．Clothes

If you live in a cold place, you must think about warmth. You might not have heat after an earthquake. Think about your clothing and bedding supplies.
