itself - there is no such thing as a high incidence rates(发病率) of cancer. Except for lung cancer,
mostly caused by cigarette smoking, the incidence rates are not on the rise. However, some kinds
of cancer are decreasing. But the fear of cancer is catching, and the country stands at risk of an
anxiety. The earth itself is coming to seem like a huge carcinogen(致癌物). The ordinary, more or
less, scientific statement that something between 80 and 90 percent of all cancers are due to things
in the environment is taken to mean that none of us will be safe until the whole environment is "cleaned
up." This is not at all the meaning.
The 80-percent calculation is based on the unthinkable differences in the incidence of cancer in
various societies around the world - for example, the high incidence of liver cancer in Africa and
the Far East, stomach cancer in Japan, breast cancer in Western Europe and North America, and
the relatively low figures for breast cancer in Japan and parts of Africa and for liver cancer in America.
These data show there may be specific environmental influences, but largely based on personal life-style,
which determines the incidence of various forms of cancer in different communities - that is all the
data suggest. The overall incidence of cancer, counting up all the cases, is probable roughly the same
everywhere.

of ice cream,bowls of noodles and plates of meatall while losing weight?
You might hate me,thinking I have one of those annoyingly good metabolisms (新陈代谢) that just
burn up fat the instant it enters my body.You might wonder if I have an intestinal (肠的) worm,or perhaps an eating disorder.Or maybe you"d just shrug your shoulders and figure I have a rich fantasy life.You"d be
wrong.
For my body to finish such a surprising task,I would have to be a mouse.Not just any mouse,but one
lucky enough to be involved in a new study at Baylor College of Medicine in Houston.
After identifying an enzyme (酶) that allows fat to be stored in the body,scientists fed mice without
those enzymes,and found those mice were able to consume far more food than other miceand still weigh
10 to 15percent less.
Best of all,the mice that had no enzymes were in very good health,producing baby mice with no
problem and generally acting like any other mouse.That"s great news for obesity researchers,who think
that scientists may figure out a way to prevent the fatmetabolizing (脂肪代谢) enzyme in humans and
control weight
gain.And such a pill would be very exciting for many struggling to get rid of dangerous extra pounds.
But don"t start planning any big dinner just yet:At this point,of course,any pill for humans is but a
twinkle (闪烁) in the eye of every medicine company"s CEO.More tests are to be made,and eventually
humans will be introduced in the test.
But for now,unfortunately,control in diet is still key.
B.Burning fat very quickly.
C.Controlling the diet.
D.Having a rich fantasy life.
B.Because the weightlosing tests were made on the mouse.
C.Because the mouse has a very good metabolism.
D.Because the author wants to try the food without the enzyme.
B.Scientists cannot find the key to identifying the enzyme.
C .Don"t overeat before the test is made on humans.
D.It is unnecessary to control weight at present.
bed before midnight, and I would almost always get up late the next morning.
But after a while I couldn"t ignore the high relationship between success and rising early. On those rare
occasions where I did get up early, I noticed that my productivity(效率)was almost always higher. So I set out to become a habitual early riser. But whenever my alarm went off, my first thought was always to stop
that noise and go back to sleep. Eventually some sleep research showed me that I was using the wrong strategy.
The most common wrong strategy is this: You assume that if you"re going to get up earlier, you"d better
go to bed earlier. It sounds very reasonable, but will usually fail.
There are two main schools (流派) of thought on sleep patterns. One is that you should go to bed and
get up at the same time every day. The second school says you should go to bed when you"re tired and get up when you naturally wake up. However, I have found both of them are wrong if you care about productivity. If you sleep at set hours, you"ll sometimes go to bed when you aren"t sleepy enough. You"re wasting
time lying in bed awake and not being asleep.
If your sleep is based on what your body tells you, you"ll probably be sleeping more thanyou need. Also, your mornings may be less predictable if you"re getting up at different times.
The solution for me has been to combine both methods. I go to bed when I"m sleepy and get up with an alarm clock at a fixed time. So I always get up at the same time (in my case 5 am), but I go to bed at different times every night - sometimes at 9:30pm, and other times at midnight. Most of the time I go to bed between 10-11 pm.
However, going to bed only when I"m sleepy, and getting up at a fixed time every morning is my way. If you want to become an early riser, you can try your own.
B. people who get up early in the morning.
C. people who feel sleepy in the morning.
D. people whose productivity is the highest in the morning.
B. Because he/she had found that his / her productivity was higher when he/she got up early.
C. Because he/she wanted to see which of the two main schools of thought on sleep patterns was right.
D. Because he/she was told the high relationship between success and rising early.
B. getting up early occasionally
C. pressing off the alarm to go on sleeping
D. asking scholars for advice on sleeping habits
B. how to have good sleep
C. wrong strategies for getting up early
D. main schools of thought on sleep patterns
Kelly Reeves was getting ready for a trip when her phone slipped into a sink full of water.
Panic moment! She quickly picked up the wet phone and tried to turn it on, but nothing worked.
Her first reaction? She got dressed, drove to the nearest store, and bought a new model at full price.
A new study finds that fear of losing your phone is a common illness. About 66 percent of those
surveyed suffer from nomophobia or "no mobile phone phobia". Interestingly, more women worry
about losing their phone than men.
Fortunately, there"s a solution.
The first step is to figure out if you have nomophobia. Checking your phone too often is one thing,
but the true sign of a problem is that you can"t conduct business or go about your routine when the fear
becomes so severe.
Do you go to unusual lengths to make sure you have your phone? That"s another sign of a problem.
If you find you check your phone plenty of times per hour, or a total of an hour per day, there may be
a problem.
Some of the treatments are similar to those for treating anxiety attacks: Leaving the phone behind
and not checking e-mail or text messages, and then learning to tolerate the after anxiety. Even if this
leads to a high level of worry and stress, the solution is to push through the fear and learn to deal with
not having your phone.
Of course, there are also technological alternatives. Luis Levy, a co-founder at Novy PR, says he
uses an application called Cerberus that can automatically track the location of his phone. To find it, he
can just go to a Web site and see the phone"s location.
He also insures his phone through a service called Asurion. The company"s description of its product
reads like a prescription for anxiety: "60 million phones are lost, stolen or damaged each year. You"ll
have complete peace of mind knowing that your phone is protected and you can quickly reconnect
with family,friends and work, as soon as the very next day!"
B. To inform us that mobile phones are useful.
C. To warn us that we should be careful.
D. To tell us we should get phones ready for a trip.
B. Fear of losing mobile phones.
C. Eagerness for new mobile phones.
D. Independence of mobile phones.
B. Learning more about modern technology.
C. Protecting one"s phone against any damage.
D. Not using a mobile phone in one"s daily work.
B. It will give you a new phone through insurance.
C. It enables you to reconnect with your acquaintance.
D. It gives you a prescription to treat nomophobia.
B. New mobile phone technology.
C. Disadvantages of mobile phone.
D. Solutions to nomophobia
about our diets, our bodies soon become loose and fatty and our systems slow moving. There are some
aspects(方面) of our unhealthy lives that we cannot avoid. I am thinking of such features of modern city life as pollution, noise, rushed meals and stress. But keeping fit is a way to reduce the effects of these evils.
The usual suggestion to a person who is looking for a way to keep fit is to take up some sport or other.
While it is true that every weekend you will find people playing football and hockey in the local park, they are outnumbered a hundred to one by the people who are simply watching them.
For those who do not particularly enjoy competitive sports-and it is especially difficult to do so if you
are not good at them-there are such separate activities as cycling, walking, jogging and swimming. What often happens though is that you do them in such a leisurely way, so slowly, that it is doubtful if you are doing yourself much good, except for the fact that you have at least managed to get up out of your armchair.
Even after you have found a way for keeping in shape, through sport or gymnastics, you are still only
half way to good health, because, according to the experts, you must also master the art of complete
mental and physical relaxation(放松). It has to do with deep breathing, emptying your mind of all thoughts, meditation, and so on. Yoga, as practiced in the West, is the most widely known and popular of the systems for achieving the necessary state of relaxation. It seems ironical (讽刺性的), though, that as our lives
have improved in a material sense we have found it increasingly necessary to go back to forms of
activity-physical effort on the one hand and relaxation on the other-which were the natural way of life of
our forefathers.
B. bad features of living in towns
C. the things we can completely do away with
D. unavoidable things in town
B. don"t do them actively enough
C. find it hard to get out of our armchairs
D. don"t find them interesting
B. keep fit and learn to relax
C. be active and practise Yoga
D. have a sound mind
B. they were careful to get plenty of fresh air
C. they spent most of the time out of doors
D. their environment was not polluted
aging and how to reverse the signs of age. The beauty industry has responded to this by offering
a wide collection of anti aging creams and other anti aging products aimed at all pocketbooks,
ranging from economical to highly priced.
And the question is "do any of these often much-vaunted (被过度吹嘘的) anti aging creams
actually work?" And if they do,how precisely do they perform their miracles?
Well the appropriate response to that is that they do work - after a fashion. There certainly are
anti aging creams available for a relatively modest price that will reduce the appearance of wrinkles
in a comparatively short period of regular application. But this really is the limit of their powers:
they won"t actually undo skin damage or eradicate (根除) all signs of age;they will simply modify
them,some more effectively than others.
The way they work is like so: they remove upper layers of dead skin cells and make deeper
layers absorb water,serving to plump them up and make them look fuller and healthier. But since
such anti aging creams only go skin deep,as it were,skin damage will reappear once you stop using
the anti aging wrinkle cream.
This means fairly heavy regular use,which might be costly depending on your choice of product.
However,if you can afford it or think it"s worth the cost,it won"t be such an issue. After all,what
woman wants to look older than her years when looking good is so tied up with many women"s
self-esteem and sense of identity.
A compromise (折中) solution for those on a tighter budget is to use the cheaper creams. In
addition,it"s always wise to be a little experimental to make sure you end up with the one that suits
our skin best.
So,to sum up: an anti wrinkle face cream will work within limits,depending on your objective.
B. anti aging foods
C. anti wrinkle face
D. anti wrinkle skin
B. skin damage must not reappear after using creams
C. anti aging creams should be properly used
D. skin damage will disappear forever after using creams
B. they make deeper layers absorb water
C. they make layers look fuller and healthier.
D. they make wrinkle faces rough
B. having a smaller amount of money
C. having no money at all
D. having a lot of money
B. easily afford your choice of product
C. think your choice of product wrong
D. believe your choice of product right
