Diets aren’t the way to go when it comes to losing weight. That’s because they create temporary eating patterns—and, therefore, temporary results. So what’s the best way to drop excess weight? Create a new normal! Weight loss is most likely to be successful when people change their habits, replacing old, unhealthy ones with new, healthy behaviors. Here are five ways to make that happen.
Take exercise.  小题1:  . Walking the family dog, cycling to school, and doing other things that increase your daily level of activity can all help you look and feel good and keep weight off.
  小题2:  One reason people get less exercise these days is that they spend too much time watching TV, looking at the computer, or playing video games. Limit recreational screen time to less than 2 hours per day.
Watch out for unhealthy drinks. Another key factor in weight gain is that more people drink sugary drinks, such as sodas, juice drinks, and sports drinks.  小题3:   
Eat some fruits and vegetables every day. Fruits and vegetables are about more than just vitamins and minerals.  小题4:   And when you fill up on friuts and vegetables, you’re less likely to overeat when it comes to high-calorie foods like chips or cookies.
 小题5:  People who don’t have breakfast often feel so hungry that they eat more later on. So they are likely to get more calories.

A. Attention must be paid to environmental factors.
B. Principles of curing cancers.
C. It will take long to find perfect cures.
D. An important discovery in the research.
E. The causative factor of cancer is very clear.
F. The survival rate differs among patients with various cancers.
小题1:___________
“I have great confidence that by the end of the decade we’ll know in vast detail how cancer cells arise,” says microbiologist Robert Weinberg, an expert on cancer. “But,” he cautions, “some people have the idea that once one understands the causes, the cure will rapidly follow. Consider Pasteur. He discovered the causes of many kinds of infections, but it was fifty or sixty years before cures were available. ”
小题2:____________
This year, 50 percent of the 910,000 people who suffer from cancer will survive at least five years. In the year 2020, the National Cancer Institute estimates, that figure will be 75 percent. For some skin cancers, the five-year survival rate is as high as 90 percent. But other survival statistics are still discouraging—13 percent for lung cancer, and 2 percent for cancer of the pancreas (胰腺) .
小题3:___________
With as many as 120 varieties in existence, discovering how cancer works is not easy. The researchers made great progress in the early 1970s, when they discovered that oncogenes, which are cancer-causing genes, are inactive in normal cells. Anything from universe rays to radiation to diet may activate an inactive gene, but how remains unknown. If several oncogenes are driven into action, the cell, unable to turn them off, becomes cancerous.
小题4:____________
The exact process involved is still mysterious, but the likelihood that many cancers are initiated at the level of genes suggests that we will never prevent all cancers. “Changes are a normal part of the evolutionary process,” says oncologist William Hayward. Environmental factors can never be totally eliminated; as Hayward points out, “We can’t prepare a medicine against universe rays.”
小题5:____________
The prospects for cure, though still distant, are brighter. “First, we need to understand how the normal cell controls itself. Second, we have to determine whether there are a limited number of genes in cells, which are always responsible for at least part of the trouble. If we can understand how cancer works, we can reduce its action. ”
