Rats eat our food or make it so dirty that it isn't fit for people at all. That's why people often kill them by laying down poison. After a day or two, they find the poison still there. The rats haven't touched it, even though it is near the food which they eat. People think they must be clever and cunning. Some scientists have been trying to find the best way to poison rats. They have watched to see just what a rat does day and night. They have found out that rats aren't so clever. They are just very shy.
Rats usually live in holes. They run from these holes to the places where they eat and drink. They have special paths on which they travel each time. So they know their paths quite well.
If anything new, such as stone or wood, is put in the path, the rats won't go near it at first as they are too frightened. It will take them many days to get over the fear. They are also frightened to go near a place that they know, where something has been taken away. If a path goes around a rock, the rats follow the same path around the rock each time. If the rock is taken away, they will still run round the place where the rock was! They won't cross the empty place, which is now open to them, even though it would be quicker.
Rats will always keep away from anything unusual to them. That's why they won't eat poison on the first or second night. They usually won't go anywhere near it for about four days until they get used to being there. Even then they only eat a little at a time.
If people want to kill rats with poison, all they have to do is to leave it out for a few days. Once the rats have got used to it, they will eat it and die.

阅读下面短文，根据所读内容在表格中的空白处填入恰当的单词。注意：每个空格只填一个单词。
Biofuels
Biofules have been around as long as cars have．At the start of the 20th century, Henry Ford planned to fuel his Model Ts with ethanol(乙醇)．But discoveries of huge petroleum deposits(储量)kept gasoline and diesel(柴油)cheap for decades, and biofucls were largely forgotten．However, with the recent rise in oil prices, along with growing concern about global warming caused by carbon dioxide emissions, biofuels have been regaining popularity．
Gasoline and diesel are actually ancient biofuels．But they are known as fossil fuels because they are made from plants and animals that have been buried in the ground for millions of years．Biofuels are similar, except that they're made form plants grown today．
Much of the gasoline in the United States in blended with a biofuel-ethanol．Countries around the world are using various kinds of biofuels．For decades, Brazil has turned sugarcane into ethanol, and some cars there can run on pure ethanol rather than as additive to fossil fuels．
On the face of it, biofuels look line a great solution．Since plants absorb carbon dioxide as they grown crops grown for biofuels should suck up about as much carbon dioxide as comes out of the tailpipes of cars that burn these fuels．And unlike underground oil reserves, biofuels are a renewable resource since we can always grow more crops to turn into fuel．
Unfortunately, it's not so simple．The process of growing the crops, making fertilizers and pesticides, and processing the plants into me!consumes a lot of energy．Also, because much of the energy used in production comes from coal and natural gas, biofiiels don't replace as much oil as they use．
What color do you like best? Do you like yellow, orange and red? If you do, you must be an optimist, a leader, or an active person who enjoys life, people and excitement. Do you prefer grey and blue? Then you are probably quiet, shy and you would rather follow than lead. If you love green, you are likely to be strong-minded and determined. You wish to succeed and want other people to see you are successful. At least this is what psychologists （心理学家）tell us. They have been seriously studying the meaning of color preference, and the effects that colors have on human beings. They tell us that we don’t choose our favorite color as we grow up. If you happen to love brown, you do so as soon as you open your eyes, or at least as soon as you could see clearly.
Black is depressing while light and bright colors make people not only happier but more active. A yellow room makes us feel more cheerful and more comfortable than a dark green one does, and a red dress adds warmth and cheer to sad winter days. It is a fact that factory workers work better, harder and have fewer accidents when their machines are painted orange rather than black or dark grey.
Remember, then, that if you feel low, you can always brighten your day or your life with a few colorful things. Also remember that you will know your friends (and your enemies) better when you find out what colors they like and dislike. And don’t forget that anyone can guess a lot about you when you choose a piece of handkerchief.

A. Because workers tend to prefer orange to other colors.
B. Because other colors are forbidden in factories.

D. Because orange machines are easier to clean.
69. Which of the following statements is Not true according to the passage?
A. It’s possible to cheer you up by enjoying some colorful pictures.
B. You can know your friends better through the color they like or dislike.
C. Some people are born with their colorful preference.
D. One’s color preference is always changeable.

Fred Michel is one of 7.2 million Americans who moonlight, or hold more than one job.
Once a week, after his day job as medical director of a mental health center, the 40-year-old psychiatrist (精神病大夫) heads to a part-time job at a treatment center for young people. Twice a month, he travels three hours to another teenage treatment center.
Last year, 5.4 percent of the American workforce held second jobs, accord
ing to the US Labor Department, and that looks set to increase this year.
Many workers like the safety that moonlighting provides, says Carl Hausamn, the writer of "Moonlighting: 148 Great Ways to Make Money to the Side."
The information from the US Labor Department shows that 40 percent of US moonlighters in 1997 took a second job to meet household expenses or pay off debts. Others save money or buy some special things.
People also take second jobs with an eye to the future - wanting to try out a new field or gain experience.
Michel started moonlighting when medical systems were unstable (不稳定的). He wanted to make sure he wasn't tied to one system that ended up failing.
Just as the purposes for moonlighting vary, the moonlighters cross all age and racial groups. And they work in a variety of industries - no longer just service, office and sale jobs.
“Technology just affects your ability to make money,” Hausman says. "That makes a frequent change in moonlighting."
As its name means, moonlighting still occurs mostly at night. And that results in some pressures. Chief among them is time.
Full-time employers could misunderstand, too. Some companies do not allow after-hour work because they fear it will affect their employees' 9-to-5 performance.
"The primary employer is saying, ‘Wait, I'm paying you for the sharp, fresh, energetic you,’” says Tom Gimbel, president and founder of LaSalle Staffing in Chicago. "If you' re burning yourself at both ends, it's going to show."
Still, the good done to the moonlighters can be great. Besides extra income, moonlighters enjoy variety, freedom and chance to do something new. They also may find their part-time jobs strengthen what they do full time.
Besides, "it's fun," Michel says. Not only do his part-time jobs offer a chance to network, stretch his professional skills and make more money, but they also give him the variety he wouldn't find just in a full-time job.
"It' s a way of pulling from the spice cabinet" he says, "and offering a little variety throughout the day."
60. What is the article mainly about?
A. The ways of moonlighting.
B. The reasons for moonlighting.
C. The problems with moonlighting.
D. The kinds of people who moonlight.
61. The reason why Fred Michel began to moonlight is that ________.
A. he found it exciting to do a part-time job
B. he needed to make ends meet with more money
C. he feared he would lose his present job one day
D. he felt more and more pressure from his employer
62. Some companies don't allow their workers to moonlight because they are afraid ________.
A. their workers can not do extra-hour work for them
B. their workers will be too tired to try their best at work
C. their workers will one day turn to some other different jobs
D. their workers will not get to work and be off work on time
63. The underlined sentence "It's a way of pulling from the spice cabinet." in the last paragraph means _________.
A. moonlighting gets you away from the job you don' t enjoy
B. moonlighting offers you freedom to make extra money
C. moonlighting strengthens your p
rofessional skills
D. moonlighting brings you chances to do something different
