Weighing the Options

Making decisions when shopping is often a tough call.Even if you’re satisfied with the first dress you try on, would you go on looking for alternatives, comparing styles and prices, until you literally dropped dead?

Psychology researchers have studied how people make decisions and concluded there are two basic styles.“Maximizers” like to take their time and weigh a wide range of options—sometimes every possible one—before choosing.“Satisficers” would rather be fast than thorough.

1. So even if they see what would seem to meet their requirements, they can’t make a decision until after they’ve examined every option to make sure that they’re making the best possible choice.Researchers followed 548 job-seeking college seniors at 11 schools from October through their graduation in June.They found that the maximizers landed better jobs.2.

“The maximizer is kicking himself because he can’t examine every option and at some point had to just pick something,” they say.“Maximizers make best decisions and end up feeling bad about them.3.

Satisficers also have high standards, but they are happier than maximizers.Maximizers tend to be more depressed and to report a lower satisfaction with life, his research found.

Faced with so many choices in our lives, we need to learn how not to waste time and energy on our decision-making.

4. For instance, if you’re picking a restaurant for a lunch meeting, first deciding on a certain part of town or type of cuisine can narrow your options.

Once you’ve arrived at a decision, stick with it.5. To limit the number of options you can consider, you can set a time limit for decision-making.Say you are buying a new bag, you could spend an amount of time studying features, price and value—but if you give yourself only five minutes to make a decision, and there are only these bags you can consider, you’ll save time.You’ll be happier with your decision, too.

A.Maximizers are people who want the best.

B.First of all, decrease your range of options.

C.Comparing is often a must when you make a decision.

D.Just accept that no decision is ever completely perfect.

E.Satisficers make good decisions and end up feeling good.

F.The other is to make decisions more accurately at the beginning.

G.Their starting salaries were 20 percent higher but they felt worse about their jobs.

The food we eat seems to have a great effect on our health. Although science has made big steps in making food more fit to eat, it has, at the same time, made many foods unfit to eat. Some research has shown that perhaps eighty percent of human illness is related to food and forty percent of cancer is related to food as well. That food is related to illness is not a new discovery. In 1945, some researchers realized that things commonly used to keep colors in meats and other food additives (添加剂) caused cancer.

Yet, these additives remain in our food, and it is difficult to know which things on the wrappings(包装)of foods are helpful or harmful. The additives which we eat are not all so direct. Farmers often give penicillin (青霉素) to their animals, and because of this, penicillin has been found in the milk of cows. Sometimes similar things are supplied to animals not for their health, but just to make a profit.

The farmers are simply trying to fatten the animals in order to get a higher price on the market. Although some countries have tried to control such things, the practice continues.

1.According to this passage, we can know _____.

A. perhaps most kinds of cancer are related to what people eat

B. perhaps most of human illness is caused by what we eat

C. cancer was discovered in 1945

D. science has made food unfit to eat

2.Things that are used to keep colors in meats are _____.

A. harmful B. useless C. helpless D. dangerous

3.People use additives _____.

A. to make food more unfit to eat

B. to cause cancer

C. to change the color of the food

D. to take off the diseases of the food

4.Which of the following is NOT true?

A. Some wrappings of food are harmful.

B. Farmers try to make more money on the market by fattening their animals.

C. "The practice continues" means "things are still going on like that".

D. We needn't take care of what we eat.

A new planet-hunting technique has detected the most earth-like planet yet around a star other than our sun, raising hopes of finding a space rock that might support life, astronomers (天文学家) reported recently.

“This is an important discovery to answer the question ‘Are we alone?’” said Michael Turner of the National Science Foundation.

“The team has discovered the most earth-like planet yet, and more importantly, has proved the power of a new technique that is sensitive (灵敏的) to detecting planets that are fit for people to live on,” Turner said in a statement.

In the last decade, astronomers have detected more than 160 planets moving around stars outside our solar system. Most of these have been gas giant planets like Jupiter, which are unfit for life.

But an international team has detected a cold planet about 5.5 times more massive than the earth — still small enough to be considered earth-like — moving around a star about 20,000 light years away, close to the center of the Milky Way.

To find this new planet, the team used a technique called gravitational microlensing (引力微观透镜法). When a planet is circling the closest star, the planet’s gravity can add its own signature to the light. This kind of light signature was observed on July 11 by a group of telescopes in a project known as OGLE, short for Optical Gravitational Lensing Experiment.

“The main advantage of microlensing is the signals for low-mass planets: They’re not weak signals. They’re just rare,” Bennett of the University of Notre Dame in Indiana said by telephone. “If there happens to be a straight line between a foreground star with its planet and the background source star, then you’re able to detect that planet.”

1.The underlined word “detected” in Paragraph 1 probably means “_________”.

A. discovered B. destroyed

C. created D. searched

2.The author’s purpose in writing this passage is to ____.

A. prove that scientists have a lot of difficulties in doing scientific research

B. explain why this planet moves around a star like our sun

C. teach the readers some basic knowledge about the universe

D. tell people about a new technique that finds the most earth-like planet moving round another star

3.From the news report we can infer that _________.

A. the planet is like the earth because it is close to the center of the Milky Way

B. it is quite possible that life may exist on other planets in the universe

C. people have no interest in finding a planet that might support life

D. the question “Are we alone” is too difficult for scientists to answer

4.Which of the following statements is NOT true according to the passage?

A. The signals coming from low-mass planets are too weak to be noticed.

B. Most of the discovered planets are not fit for people to live on.

C. If a star with its planet happens to be in line with the source star, then the planet can be found.

D. The power of the new technique is proved by the discovery of the earth-like planet.

House Sitting

In many countries of the world people do what is called house sitting. It means that if owners of the house are going away, they want someone to come into their home and look after the house and maybe pets while they are away.

In Australia, many people travel. After people retire, they might buy a van and travel all over the country. 1.

So if someone wants to travel or go away for some reason, they might want someone in their home to care for it and keep the gardens tidy. House sitters might have to care for pets. Also, quite a few people have swimming pools in their back yard and they need cleaning. 2.I feel it is a great way of seeing the country, because you go and stay in a new city, get to meet new people, and have time to go sightseeing in a new area.

3. There are websites where you find the advertisements by people who want to travel, and by replying to the advertisement, you can make arrangements to go and look after their home.

There are some requirements to be a house sitter. You must be a trusted person, so that the home owner knows you will not steal anything. You must be able to go when the house owner wants you to go, so you need lots of free time.4. You need to be good with pets, able to care for cats and dogs, or other pets they may have.

Some house sitting jobs are just for a few days or a couple of weeks while the house owner have a short holiday. Sometimes it is for much longer. We have had one house sit for six months, while the home owner travelled to Europe.

5. Then you can travel to many different countries and stay there. One of the important things to get are references from the home owners where you have stayed. A reference is a written letter to say that you are trustworthy and have looked after their home well. You can show these letters to prospective house sitting jobs and they know you will do a good job.

A. I have done house sitting many times.

B. Thousands of people do this all the time.

C. It is also possible to do house sitting in other countries.

D. Generally you have many opportunities to get a house sitting job.

E. You must take a little care over what your description says about you.

F. This is an international house sitting service for all city and country areas.

G. You must have a good car, so you can travel to different parts of the country.
