While it is impossible to live completely free of stress, it is possible to prevent stress as well as reduce its effect when it can’t be avoided． 76
● 77 When you are nervous，angry or upset, try releasing the pressure through exercise or physical activity．Running, walking, playing tennis, and working in your garden are just some of the activities you might try．
●Take care of yourself
78 If you easily get angry and can’t sleep well enough, or if you’re not eating properly, it will be more likely that you will fall into stressful situations．If stress repeatedly keeps you from sleeping, you should consult a doctor．
●Make time for yourself
Schedule time for both work and entertainment．Don't forget, play can be just as important to your overall well-being as work． 79 Go window-shopping or work on a hobby．Allow yourself at least a half hour each day to do something you enjoy．
● 80
Stress can result from disorganization and a feeling that “there’s so much to do, and not enough time”．Trying to take care of everything at once can be too much for you and as a result, you may not achieve anything．Instead, make a list of everything you have to do, then do one thing at a time, checking off each task as it is completed．Set out to do the most important task first．
|
A．Do whatever you like and want to do． |
|
B．You should make every effort to eat well and get enough rest． |
|
C．Make a list of things to do． |

D．Try physical activity． |
E．You need a break from your daily routine to just relax and have fun．
F．You could smile to yourself in front of a mirror every day．
G．The following are suggestions for ways to deal with stress．
A purple tomato genetically engineered to contain nutrients more commonly seen in dark berries helped cancer in mice, British researchers said on Sunday. The finding, published in the journal Nature Biotechnology, bolsters the idea that plants can be genetically modified(changed) to make people healthier.
Cancer-prone mice fed the modified fruit lived significantly longer than animals fed a standard diet with and without regular tomatoes, Cathie Martin and colleagues at
the government-funded John Innes Center in Britain reported. “The effect was much bigger than we had expected.” said Martin, a plant biologist.
The study focused on anthocyanins，a type of antioxidant found in berries such as blackberries and blackcurrants that have been shown to lower risk of cancer, heart diseases and some neurological diseases. While an easy way to improve health, many people don’t eat enough of these fruits, the researchers said. Using genes from the snapdragon flower, the researchers discovered they could get the tomatoes to make anthocyanins---- turning the tomato purple in the process.
Mice genetically engineered to develop cancer lived an average of 182 days when they were fed the purple tomatoes, compared to 142 days for animals on the standard diet. “It is greatly encouraging to believe that by changing diet, or specific components in the diet. You can improve health in animals and possibly humans.” Martin said in a telephone interview.
The researchers warned that trials in humans are a long way off and the next step is to investigate( look into) how the antioxidants actually affect the tumors to promote better health. But the findings do support the formal research suggesting that people can significantly improve their health by making simple changes to the daily diet, other researchers said.
“It’s exciting to see new techniques that could potentially make healthy foods even better for us.” said Doctor Lara Bennett, science information office at Cancer Research UK. “ But it is too early to say whether anthocyanins obtained through diet could help to reduce the risk of cancer.”
