单选题根据以下材料，回答题
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 givesquirrels 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. The Council approved, and Councilwoman Bess LaRiviere 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. 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 rop_. 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
D． Showing them how to use the bridge

参考答案D

单选题根据以下材料，回答题
Even a small reduction in salt in the diet can be a big help to the heart. A new study used a computer model to predict how just three grams less a day would affect heart disease in the United States.
The result: thirteen percent fewer heart attacks. Eight percent fewer strokes. Four percent fewer deaths. Eleven percent fewer new cases of heart disease. And two hundred forty billion dollars in
health care savings.
Researchers found it could prevent one hundred thousand heart attacks and ninety-two thousand deaths every year.
The study is in the New England Journal of Medicine. Kirsten at the University of California,was the lead author. She says people would not even notice a difference in taste with three grams,or one-half teaspoon, less salt per day. The team also included researchers at Stanford and Columbia University.
Each gram of salt contains four hundred milligrams of sodium, which is how foods may list their salt content.
The government says the average American man eats ten grams of salt a day. The American Heart Association advises no more than three grams for healthy people. It says salt in the American diet
has increased fifty percent since the nineteen-seventies, while blood pressures have also risen.Less salt can mean a lower blood pressure.
New York City Mayor Michael Bloomberg is leading an effort called the National Salt Reduction Initiative. The idea is to put pressure on food companies and restaurants.
Mayor Bloomberg has already succeeded in other areas, like requiring fast food places in the city to list calorie information. Now a study by the Seattle Children's Research Institute shows how
that idea can influence what parents order for their children.
Ninety-nine parents of three to six year olds took part. Half had McDonald's menus clearly showing how many calories were in each food. The other half got menus without the calorie information.
All the following are related to the salt in diet except

A． Strokes
B． heart attacks
C． blood pressures
D． stomach diseases
