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.

16．From the text we know that “ACE inhibitors” are ________．

A．a kind of medicine B．a kind of protein C．a kind of illness D．a kind of food

17．According to what Professor Bruce 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

18．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 19．The text is meant ________．

A．to introduce scientific findings about eggs B．to introduce a medicine made from eggs

C．to tell people how to lower their blood pressure D．to advise people to eat as many eggs as possible

San Francisco has its cable cars. Seattle has its Space Needle. And, Longview has its squirrel bridge. The bridge, which has attracted international attention, is now a local landmark.

The Nutty Narrows Bridge was built in 1963 by a local builder, Amos Peters, to give squirrels a way to cross the busy road without getting flattened by passing cars.

The original bridge was built over Olympia Way on the west edge of the library grounds. Before the bridge was built, squirrels had to avoid traffic to and from the Park Plaza office building where office staff put out a nutty feast for the squirrels. Many times, Peters and others who worked in and near Park Plaza witnessed squirrels being run over.

One day Peters found a dead squirrel with a nut still in its mouth, and that day's coffee break discussion turned into squirrel safety. The group of businessmen cooked up the squirrel bridge idea and formed a committee to ask the blessing of the City Council(市政会). The Council approved, and Councilwoman Bess LaRiviere jokingly named the bridge “Nutty Narrows”．

After architects designed the bridge, Amos Peters and Bill Hutch started construction. They built the 60-foot bridge from aluminum and lengths of fire hose(消防水带). It cost $1，000.

It didn't take long before reports of squirrels using the bridge started. Squirrels were even seen guiding their young and teaching_them_the_ropes. The story was picked up by the media, and Nutty Narrows became known in newspapers all over the world.

In 1983, after 20 years of use, Peters took down the worn-out bridge. Repairs were made and crosspieces were replaced. The faded sign was repainted and in July 1983, hundreds of animal lovers attended the completion ceremony of the new bridge.

Peters died in 1984, and a ten-foot wooden squirrel sculpture was placed near the bridge in memory of its builder and his devotion to the project.

A. Passing them a rope.

B. Directing them to store food for winter. C. Teaching them a lesson.
