Losing weight comes with a lot of health benefits—including making your brain sharper.

There have been few studies of overweight and cognitive functioning, (认知功能) possibly because it is generally believed that it is not a primary risk cause for poor cognitive performance. Yet, it turns out that overweight may damage cognitive functions such as memory and attention. Losing weight, therefore, may help improve these mental functions, according to a new research led by John Gunstad, assistant professor of psychology at Kent State University.

Growing evidence suggests that being fat is linked to cognitive deficits (缺陷). So Gunstad and his team guessed that losing weight might improve mental function. For their study, they measured memory and attention in a group of 150 overweight participants, some of whom had some kind of operation for weight loss and some did not. All of the volunteers completed mental skills tests to assess their abilities of memory and attention at the beginning of the study, and again 12 weeks later. To begin with, about 24% of the patients showed damaged learning and 23% showed signs of poor memory when tested. At the end of the study, those who had lost weight after operation improved their scores into the average or above average range for cognitive functions. Scores for the volunteers who didn’t lose weight dropped even further.

The study helped Gunstad to find out whether losing weight had any effect on mental function. Now that he’s seen the positive effect that weight loss can have on memory and attention, he says he will next study those who choose to lose weight by the traditional way—eating healthier and getting more active. He expects that losing weight in this way will have a similarly positive effect on the brain. “If we can improve the condition with operations, then we can probably produce the same change with behavioral weight loss as well,” he says.

1.There is less research on overweight and cognitive functions because researchers _____.

2.The result of Gunstad’s study shows that ______.

3.What is Gunstad planning to prove next in his research?

4.Which of the following is the best title for the text?

A. Body Weight and Health

B. Losing Weight by Operation

C. Ways to Improve Mental Functions

D. Losing Weight to Sharpen Your Mind

Although honey is a natural food with many health benefits, you should avoid giving it to your child until they are a year old. This is because there’s a small chance that it could contain a bacterium (细菌), which can result in infant botulism (婴儿型肉毒中毒): a serious form of food poisoning.

Unfortunately, it’s not possible for manufacturers to destroy the bacteria without cooking the honey, which makes the sweet matter unsuitable for babies under one. Although the British Honey Importers and Packers Association advises its members to print on honey labels that it’s not suitable for babies under 12 months, all products will not carry the warning. So it’s up to you to remember not to add honey to your baby’s food.

Although you may feel your baby’s food could do with a spoonful of honey for sweetness, it’s a good idea to avoid giving her too many sugary tastes. Offering too many sweet foods could mean that your baby develops a sweet tooth.

If, however, adding sweetness to certain foods will help. There are plenty of alternatives to honey. Try low-sugar jams on fingers of toast or in sandwiches. You can also sweeten the flavor of sharp or sour fruit such as rhubarb (大黄) by adding jams like apples or pears.

Once your baby is over a year old, it’s safe to introduce honey. By this time, a child’s intestines (肠) have grown enough to process the dangerous bacteria without allowing it to grow. However, because honey is a type of sugar, nutritionists still advise you should limit the amount to avoid problems as to tooth later on.

1.Why should we avoid giving honey to a baby?

A. Because too much honey will ruin the baby’s teeth.

B. Because a bacterium can cause food poisoning.

C. Because honey can make babies lack appetite.

D. Because honey will lead t0 infant depression.

2.From the second paragraph we can infer that 　　　　 .

A. honey manufacturers will remove the bacteria by cooking

B. every honey product will carry a label in the market

C. some products will carry a label while in the market

D. parents can accuse manufacturers of their products

3.The underlined sentence in the passage means that 　　　　 .

A. we have no choice except honey

B. we have many choices apart from honey

C. we can choose honey and other things

D. we can’t choose honey or other things

4.Which of the following is the best title for the passage?

A. Why Is Honey Dangerous for Your Baby?

B. When Can You Feed Your Baby with Honey?

C. How Does Honey Benefit Your Baby?

D. What Can You Do with Honey for Your Baby?

What can be better than a sweet treat with health benefits? As it happens, our favourite February food, chocolate, has a few shinning characteristics. It comes from the Theobroma cacao tree (food for the Gods), from a bean that grows on that tropical tree. Chocolate originated in Mexico and Central and South America, but West Africa now produces most of the world’s cocoa. Look for fair trade chocolate that meets environmental and labour standards at natural foods markets in Kitsilano and the West End, at Karmavore in New Westminster and at Nature’s Fare Markets throughout the province.

Dark or semisweet chocolate is typically a vegan(素食) product. Because chocolate contains antioxidants（抗氧化剂） that prevent the oxidation （氧化）of LDL (bad) cholesterol（胆固醇）, it has gained a reputation of being beneficial for our heart health. Eaten in an appropriate amount, chocolate may lower blood pressure.

Chocolate is also a source of iron – a “precious metal” when it comes to human health. As part of red blood cells, iron plays a central role in transporting oxygen to the body and carrying away the waste product carbon dioxide. Each day, we lose tiny amounts of iron in cells that are missing from skin and the inner lining of the intestine(肠壁). If our intake is not enough to replace our losses, a tired feeling and sensitivity to cold may develop. With further consuming, people feel exhausted, chilly and even headaches; the skin may appear pale. Since iron absence is such an obvious condition and easily diagnosed, if you have any doubts about your iron level, have a lab test done.

We are good at recycling iron, however, losses must be replaced. Two of the Chocolate Butter Balls in the recipe(食谱) below will provide one quarter of the recommended intake of eight mg iron for the day.

1.Which region produces most of the world’s cocoa now?

A. Mexico　　 B. Central America

C. South America　　 D. West Africa

2.Why is chocolate beneficial for our heart health?

A. It contains antioxidants　　 B. It comes from the cacao tree.

C. It originates in Mexico.　　 D. It is a sweet treat.

3.What does “chilly” in the third paragraph mean?

A. easy to be angry　　 B. having a fever

C. sensitive to cold　　 D. feeling tired

4.From which is the text probably taken?

A. A biology textbook.　　 B. A health magazine.

C. A research paper.　　 D. A travel brochure.
