Starting the day on an egg could keep your blood pressure(血压) under control, research suggests.Scientists have shown that eggs produce proteins with a function similar to that of powerful blood pressure-lowering drugs.

The research, from the University of Alberta in Canada, showed that when eggs come in contact with stomach enzymes(酶) they produce a protein that acts in the same way as Ace inhibitors, but more work is needed to show the effects outside a lab and in the human body.

Earlier this month, British researchers declared that, contrary to popular beliefs, it is healthy to go to work on an egg.They concluded that the type of cholesterol (胆固醇) found in eggs has little effect on increasing heart disease risks.

Researcher Professor Bruce Griffin, from the University of Surrey, said:“The wrong beliefs linking egg eating to high blood cholesterol and heart disease must be corrected .The amount of fat in our diet has an effect on blood cholesterol that is several times greater than the relatively small amounts of cholesterol found in eggs.The UK public do not need to be limiting the number of eggs they eat.They can be encouraged to include them in a healthy diet as they are one of nature’s most nutritious foods.”

The British Heart Foundation dropped its three-egg-a-week limit in 2005.However, almost half of Britons believe the limit still applies.

A.a kind of medicine       B.a kind of protein  

C.a kind of illness         D.a kind of food

54.According to what Professor Brcue said, eggs______.

A.are the most nutritious food.

B.have no effect on blood cholesterol

C.can be included in a healthy diet  

D.are forbidden to be eaten in the UK

55.We can infer from the text that______.

A.drugs to lower blood pressure will be replaced by eating eggs

B.stomach enzymes mixed with eggs can cure heart diseases

C.most Britons agree the three-egg-a-week limit should be dropped

D.about 50% of Britons think eating an egg a day is bad for their health

56.The text is meant______.

A.to introduce scientific findings about eggs

B.to introduce a medicine made from eggs

For thousands of years, man has enjoyed the taste of apples. Apples, which are about 85 percent water, grow almost everywhere in the world but the hottest or coldest areas. Among the leading countries in apple production are China, France and the United States.

   There’re different kinds of apples, but a very few make up the majority(大多数) of those grown for sale. The three most common kinds grown in the United States are Delicious, Golden Delicious and Mclntosh.

   Apples are different in color, size and taste. The color of the skin may be red, green or yellow. They are of different size, with Delicious apples being among the largest. The taste may be sweet or tart(酸). Generally, sweet apples are eaten fresh while tart apples are used to make applesauce(苹果酱).
