[单项选择]There’s a simple idea that two of West Germany’s top car manufacturers are seriously studying at the moment, both out of self interest, but also out of concern for the environment.
The concept is to develop vehicles that can run on a virtually limitless element hydrogen which when burned does not produce damaging fumes, but instead a bit of water vapour. The concept can solve two problems at once. First, it is a hedge for that day in the 21st century when hydrocarbon fuels run out, a prospect of no minor concern for the automotive industry.
Beyond that, the increasingly dire warnings by environmental scientists about the "greenhouse effect" in atomosphere caused by carbon dioxide exhausts adds urgency to the quest for a fuel that is less damaging to the environment.
Of course, there is a hitch to hydrogen, both carmakers admit : though the know - how to run vehicles on nature’s lightest element is already available, hydrogen is far from being cost competitive compared to
A. It is nontoxic.
B. It has lots of vapour.
C. It doesn’t produce damaging fuels.
D. It costs less.
[单项选择]Student loans are based on a simple idea: that a graduate’s future flow of earnings will more than cover the costs of doing a degree. But with unemployment rates in parts of the rich world at post-war highs, that may no longer hold true for many people. The consequences will be felt by everybody.
All over the world student indebtedness is causing problems—witness this month’s violent protests in Chile. In Britain, according to a recent parliamentary report, rising university fees mean that student debt is likely to treble to ￡70 billion by 2015. But, partly because higher education there is so expensive, the scale of the problem is far greater in America. When the next official estimates of outstanding student debt there are published, it is expected to be close to $1 trillion, higher than credit-card borrowing. Credit quality in other classes of consumer debt has been improving; delinquency rates on student loans are rising.
Many of the anti-Wall Street protesters push the i
A. high unemployment rates make it hard for students to get loans
B. rising university fees is a valid way to balance the student loans
C. student indebtedness has become an increasingly tricky issue
D. credit quality has been improved including student debts

Born in 1879, in Ulm, Germany, Einstein was two years old when his parents moved to Munich. There his father opened a business in electrical supplies. As a boy, Einstein did not learn to talk until later than others of his age, and in his early childhood he was not considered especially bright. But by the time he was 14 years old, he had taught himself advanced mathematics from textbooks. By them he knew what he wanted to be when he grew up. He wanted to be a physicist and &vote himself to research.
Einstein could not afford to pay for the advanced education he needed, because his family business had declined. Later, he and his family were forced to leave Munich to live in Milan, Italy, where they had relatives. As for him, the family did manage to send him to a technical school in Switzerland, and later to the Federal Institute of Technology in Zurich. In 1901, when Einstein was 22 years old, he began teaching, and in 1902, be went to work as a patent office examiner
A. Patiently.
B. Intelligently.
C. Indifferently.
D. Vividly.
