Every scientific field uses the scientific method to conduct experiments. Performing experiments is very important in the field of psychology (心理学). Before beginning a study, however, any scientist who wishes to perform an experiment should be familiar with the steps of the scientific method. 1.

◆ Form a hypothesis (假设). It is an educated guess about what will happen during the study. 2. Coming up with a hypothesis before you start can help guide your experiment.

◆ Plan out a study. Planning out the experiment is essential because the psychologist needs to know if they have time, materials, and testing area prepared beforehand. This step also helps the scientist to determine if they will be performing descriptive or experimental research. The ideal situation is to always perform experimental research. 3. Descriptive research simply collects data regarding the problem and forms a hypothesis according to the data.

◆ Collect data. 4. If the data collected is not recorded and organized, the entire efforts of the study may be wasted. The best way to do this may be to record the proceedings so that no details are lost.

◆ Analyze the data. Once all the data has been collected and organized, it must be analyzed. Using previous research or scientific information about the problem, the psychologist must apply the new data gathered.

◆ Publish the information learned. The final step of the scientific method in psychology is publishing the results of the study. 5. Most psychological experiments are published in scientific journals.

A. It is based on scientific facts, not just opinions.

B. Read on to find out how to use the scientific method in psychology.

C. Before psychologists start the experiment, they must plan out the steps.

D. This helps other psychologists to learn about and use the new information.

E. The scientific method has proved to be an effective way to conduct research.

F. To fully understand the study, each part of the experiment must be recorded.

G. Sometimes, however, this is impossible and descriptive research will have to be used.

Ask someone what they have done to help the environment recently and they will almost certainly mention recycling. Recycling in the home is very important of course. However, being forced to recycle often means we already have more material than we need. We are dealing with the results of that over-consumption in the greenest way possible, but it would be far better if we did not need to bring so much material home in the first place.

The total amount of packaging increased by 12% between 1999 and 2005. It now makes up a third of a typical household’s waste in the UK. In many supermarkets nowadays food items are packaged twice with plastic and cardboard.

Too much packaging is doing serious damage to the environment. The UK, for example, is running out of it for carrying this unnecessary waste. If such packaging is burnt, it gives off greenhouse gases which go on to cause the greenhouse effect. Recycling helps, but the process itself uses energy. The solution is not to produce such items in the first place. Food waste is a serious problem, too. Too many supermarkets encourage customers to buy more than they need. However, a few of them are coming round to the idea that this cannot continue, encouraging customers to reuse their plastic bags, for example.

But this is not just about supermarkets. It is about all of us. We have learned to associate packaging with quality. We have learned to think that something unpackaged is of poor quality. This is especially true of food. But it also applies to a wide range of consumer products, which often have far more packaging than necessary.

There are signs of hope. As more of us recycle, we are beginning to realise just how much unnecessary material is collecting. We need to face the wastefulness of our consumer culture, but we have a mountain to climb.

1.What does the underlined phrase “over-consumption” refer to?

A. Using too much packaging.

B. Recycling too many wastes.

C. Making more products than necessary.

D. Having more material than is needed.

2. The author uses figures in Paragraph 2 to show _______.

A. the tendency of cutting household waste

B. the increase of packaging recycling

C. the rapid growth of super markets

D. the fact of packaging overuse

3.What can be inferred from Paragraph 4?

A. Unpackaged products are of bad quality.

B. Supermarkets care more about packaging.

C. It is improper to judge quality by packaging.

D. Other products are better packaged than food.

4.What can we learn from the last paragraph?

A. Fighting wastefulness is difficult.

B. Needless material is mostly recycled.

C. People like collecting recyclable waste.

D. The author is proud of their consumer culture.

Dear Jeremy and Alice,

Although we’ve been delighted to have you as neighbors, we’re hoping to settle something that bothers to us. In a word, your dog—Cleo.

The early morning barking have been disturbing us as we are often up all night with the baby. Beside, Cleo tends to bark a average of six hours a day. This morning she starts barking even before 5 o’clock. That is too much for us. considering how closely the houses are.

We appreciate our apologies and goodwill, but we hope which you can figure out a good way of settling the matter.

Do you drink water that's been left sitting out overnight or even for another day? Have you noticed it tastes different?

Tap water that has been left to sit out slowly begins to acquire an off taste. Many people think that this is because of microorganisms(微生物). But that's not what makes old water taste not fresh. For that we can thank carbon dioxide. After about 12 hours, tap water starts to go flat as carbon dioxide in the air starts to mix with the water in the glass, lowering its pH and giving it an off taste. But it's most likely safe to drink.

However, back to those microorganisms. If you use a dirty glass day after day, there is more of a chance of bacteria making themselves known; a risk that increases if you share the glass with another mouth as well. But assuming you use a fresh glass every few days, you probably won't have a problem unless the glass has been touched by dirty fingers, and especially if those dirty fingers went unwashed after using the bathroom.

As for plastic water bottles that have been left out in the sun or in the car, step away from the bottle, warns Dr. Kellogg Schwab, director of the Johns Hopkins University Water Institute. "A chemical called bisphenol-A, or BPA, along with other things used to make plastic can leach(过滤) into your water if the bottle heats up or sits in the sun," he explains. BPA, as you probably know, has been linked to everything from heart disease to cancer.Schwab also adds that plastic used for commercial bottled water isn't meant to be washed or refilled, so use only one time and recycle. Or don't buy them at all; use refillable water bottles instead.

1.Tap water begin to acquire an off taste because of .

A. BPA B. the glass

C. the microorganism D. carbon dioxide

2. According to Paragragh 2 , tap water that's been left sitting out for 12 hours____.

A. tastes better B. is still safe to drink

C. contains few microorganisms D. is most likely undrinkable

3. What should we do with plastic water bottles that have been left out in the sun or in the car?

A. Throw them away. B. Refill them with fresh water.

C. Use them after they cool down. D. Clean them and use them again.

4.Which of the following is true about BPA?

A. It is safe for people to use.

B. It is a kind of new material.

C. It can cause great harm to people.

D. It is the main material to make plastic.

When I come across a good article in reading newspapers, I often want to cut and keep it. But just as I am about to do so, I find the article on the side is as much interesting. It may be a discussion of the way to in good health, or about how to behave and conduct oneself in society. If I cut the front article, the opposite one is likely to damage, leaving out half of it or keeping the text the title. Therefore, the scissors would before they start, .halfway done when I find out the result.

Sometimes two things are to be done at the same time, both worth your .You can only take up one of them, the other has to wait or be up. But you know the future is unpredictable(不可预料) — the changed situation may not allow you to do what is left . Thus you are in a difficult position and feel sad.
