Starting the day on an egg could keep your blood pressure (血壓) 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 (膽固醇) 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

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

4.The text is meant to .

A. introduce scientific findings about eggs

B. introduce a medicine made from eggs

C. tell people how to lower their blood pressure

D. advise people to eat as many eggs as possible

2．Shyness is the cause of much unhappiness for a great many people．Shy people are anxious and self-conscious； that is，they are concerned with their own appearance and actions too much．Negative thoughts are constantly occurring in their minds：What kind of impression am I making？Do they like me？Do I sound stupid？Am I wearing unattractive clothes？
It is obvious that such uncomfortable feelings must affect people unfavorably．A person's self-concept is reflected in the way he or she behaves and the way a person behaves affects other people's reactions．In general，the way people think about themselves has a deep effect on all areas of their lives．
Shy people，who have low respect，are likely to be passive and easily influenced by others．They need faith that they are doing"the right thing"．Shy people are very sensitive to criticism．Itmakes them feel inferior（自卑）．They also find it difficult to be pleased by praises because they believe they are unworthy of praise．A shy person may respond to a praise with a statement like this one："You're just saying that to make me feel good，I know it's not true．"It is clear that，while self-awareness is a healthy quality，overdoing it is harmful．
Can shyness be completely got rid of，or at least reduced？Fortunately，people can overcome shyness with determination since shyness goes hand in hand with lack of self respect．It is important for people to accept their weakness as well as their strengths．Each one of us has his or her own characteristics．We are interested in our own personal ways．The better we understand ourselves，the easier it becomes to live up to our chances for a rich and successful life．

29．The first paragraph is mainly aboutA．
A．the effect of shyness on people

D．a(chǎn) weak point of shy people
31．The underlined word"it"in Paragraph 3 refers toB．
A．shyness    
B．criticism   
C．sensibility  
D．praise
32．We can learn from the passage that shyness canD．
