[单项选择]A recent study shows that more and more Americans are choosing to work at home.
There are several reasons for the change. One reason is many parents want more time to be with their children at home. Another is that people want the freedom to decide for them- selves how and when to do their job. The chance to work at home lets people live wherever they wish—out in the country, perhaps. It also makes it possible for many others—disabled and other persons, new mothers-to do useful work and earn money.
About half the people who work at home operate their own business. They sell products or services. The other half works for companies. They may make things, such as clothes. Or they may do office work, such as copying letters. A smaller number work at highly skilled jobs as designers or engineers.
The revolution(革命) in computer technology is one of the main reasons for the change to working at home.
Computers are now used in almost every American workplace in offices, in
A. get a higher pay
B. have enough time to stay with their children
C. have more time for rest
D. do more housework
[单项选择]A new international study shows that six people die every minute from smoking. That equals 3 million deaths around the world every year. If the present rate (率)of smoking continues, the number of deaths each year from smoking could rise to 10 million by the year 2020.
The study describes smoking as the biggest cause to deadly diseases among grown-ups in industrial countries. So far most of the smoking deaths have happened on men, especially in developing countries.
A researcher at the World Health Organization says 70% of Chinese men smoke more than 15 cigarettes each day. In Latin America about 50% of the men are smokers. There also is a very large number of smokers in the former Soviet Union(苏联)and in the east Europe. And 25% of all smoking deaths worldwide are in those areas of the world. Scientists say smoking will kill 50% of the countries.

[单项选择]A new study shows that students learn much better through an active, iterative (反复的) process that involves working through their misconceptions with fellow students and getting immediate feedback from the instructor.
The research was conducted by a team at the University of British Columbia (UBC), Vancouver, in Canada, led by physics Nobelist Carl Wieman. In this study, Wieman trained a postdoc, Louis Deslauriers, and a graduate student, Ellen Schelew, in an educational approach, called "deliberate practice," that asks students to think like scientists and puzzle out problems during class. For 1 week, Deslauriers and Schelew took over one section of an introductory physics course for engineering majors, which met three times for 1 hour. A tenured physics professor continued to teach another large section using the standard lecture format. The results were dramatic: After the intervention, the students in the deliberate practice section did more than twice as well on a 12-question

B. An introductory physics course was given to physics majors.
C. Students were first taught by the "deliberate practice" approach.
D. A professor taught the same section with the traditional lectures.
