appeared to be some disagreement among scientists as to what effect this might have on humancaused
global warming. Now climate scientists agree a less active sun won"t have much of an effect.
According to the reports from the IPCC, global climate is expected to warm between 4 and 10
degrees Fahrenheit by the year 2100. On the other hand, scientists show that the reduction in radioactive
forcing due to low solar activity would reduce world temperature half a degree F if the lull in solar activity
lasted until the end of the 21 century.
It is highly unlikely the current lull in solar activity would have such a long period. "It is more likely that a new lull in solar activity would reduce the global temperature average of 0.2 Celsius by the end of
2100," commented Professor Stefan Rahmstorf, who was responsible for a study of a lull in solar activity
effects on climate at the Institute for Research on the Impacts of Climate Change in Potsdam.
In short, this small forcing is likely to have little, if any, observable effect on humancaused global
warming,at most reducing the temperature increase to between 3.5 and 9.5 degrees F. The reason for
the small effect on temperature is due to the fact that the difference between solar activity highs and lows
changes solar output by less than one half of one percent. So the difference in the amount of energy
coming out of the sun between solar highs and lows isn"t very large. The result is that the human forcing
on climate is many times larger than that caused by any natural difference in the sun.
Generally if humancaused climate_change isn"t controlled it can"t be stopped by natural changes in the
sun.
B. That humans are responsible for global warming.
C. That humans are stronger than nature.
D. Whether the lull in solar activity has effect on humancaused global warming.
B. more trees are planted
C. redioactive forcing becomes strong
D. the lull in solar activity lasts a long period
B. The current lull in solar activity will last very long.
C. The power of humans is stronger than the sun on global warming.
D. The IPCC reported that world temperature would fall greatly.
B. Global warming.
C. The earthquake.
D. Global environmental change.
B. An argument among scientists.
C. That humans are a cause of global warming.
D. That a less active sun cannot stop global warming.
答案
6. Now climate scientists have done some research on a lull in solar activity and agreed a less active sun
won"t have much of an effect.

even children are getting overweight. Today some of the newborn babies are also born fat. It has been
proved that the people living in the developed Western countries are more likely to become overweight.
There are a number of causes behind this.
The people in the developed countries including the United States almost enjoy all the comforts of life. Almost all the things in the lives of the people living in these countries are at their fingertips. A very limited
amount of movement and physical effort is required to do any kind of job. Because of the fact that these
countries are quite developed, most of the jobs that the people take up are desk jobs. So the lifestyle of
them is just around the office desk.
Most of the developed Western countries are cold ones. Nature demands that people eat the food
that can somehow make them stand the coldness. Therefore, wine fatty dairy products, bread, junk food
and red meat become an important diet in these countries.
However, the blame cannot be entirely put on the unhealthy eating habits of the people. Technology
allows them to import almost all the foods products that they do not grow. Although some healthy food
are grown in the countries nowadays, the quantity is very limited. It is not enough to meet the demand.
So when they are not available and fatty foods are cheaper, then people prefer to go for the eating habit
that they have always been following.
B. management
C. desk
D. tiring
B. gene(基因)
C. education
D. weather
B. the people in the developed countries
C. the fatty foods
D. the unhealthy eating habits
B. remind people of the relation between food and weight gain
C. inform people of the causes of weight gain in the developed countries
D. tell people that fatness in the developed countries is natural
B. blame the fatness on the weather
