[单选题]Years ago our cities were full of cars,buses and trucks．Now the streets are completely congested(拥挤的)and it is very difficult to drive a car along them．Drivers must stop at hundreds of traffic lights．What are our cities going to be like in ten or twenty years?Will enormous(巨大的)motorways be built across them?With-big motorways cutting across them,full of noisy,dirty cars and lorries,our cities are going to be awful places．How can we solve the problem?
There are some good ideas to reduce the use of private cars．In 1989,for example,the authorities in Rome began an interesting experiment:passengers on the city buses did not have to pay for their tickets.
In Stockholm there was another experiment:people paid very little for a season ticket to travel on any bus,trolley bus,train or tram in all the city.
In many cities now some streets are closed to vehicles,and pedestrians are safe there.
In London there is another experiment:part of the street is for buses only,so the buses can travel fast．There are no cars or taxies in front of them.
What the writer worries about in a big city is__.
A.the number of traffic lights
B.the shortage of buses
C.the lack of motorways
D.the traffic congestion

[填空题]The US health care costs have doubled in the last 30 years, but Americans are not
1
healthier than they were in the 1980"s. Hamilton Moses analyzed the changes and trends and
2
his findings.
The researchers found Americans spent between $2.5 trillion and $3 trillion on health care in 2011, more than any other developed country. The report highlights two major factors that
3
costs.
The first is that the price of medical and
4
services has gone up, along with the cost of drugs, procedures and devices. Moses says Americans" love of technology is part of the problem—they look to technology for the solution of all problems. The second factor is simple to identify, but more complex to address. Poor lifestyle habits, such as smoking and over-eating, have resulted in
5
levels of obesity and diabetes as well as heart disease and lung diseases. Managing chronic disease is expensive. Many of these diseases can be prevented through exercise, diet and
6
a healthy weight, yet in the US prevention has not historically been part of medical care.
7
a nutritionist or participating in wellness activities can be expensive, and those services are not normally
8
by health insurance.
Moses" research shows that those who spend the most on chronic disease are not elderly, and that their investment in care does not
9
a long life.
Meanwhile, a new report from the Organization of Economic Cooperation and Development shows that the US spends between 250% to 300% of what other member nations spend. Despite that, the US trails other developed countries in
10
, coming in at 26th place out of the 36 members of the organization.
