The right pair of exercise shoes can do a lot to prevent discomfort and injuries, personal trainers say. Here are some shopping tips:

【1】 Depending on your workout, shoes designed for walking, running, tennis, cross-training or another specialty will provide the best support for your feet.

Shop when you normally exercise. Feet actually get bigger throughout the day, sometimes swelling up as much as a half-size by nighttime. 2

Try them on. Never grab a pair of exercise shoes based only on the size of footwear you normally buy. Bring the type of socks you’d wear to work out and go for a walk through the store.

3 You should be able to spread your toes out comfortably. Make sure there’s about a half-inch of space between them and the front of the shoe. The back should fit snugly (warmly and comfortably) against your heel and not move up and down. If your feet are different sizes, buy based on the larger one.

Talk to an expert. Shoe salesmen and personal trainers can study your stride (步伐) and the shape of your feet. 4

5 Many trainers recommend switching footwear every three to five months, if possible, to maintain proper cushioning and support.

One tip: if you have to tie your shoes very tightly to feel a good amount of support, they may be ready to go.

A. Think about how much you can afford to buy the workout shoes.

B. Consider your type of exercise.

C. Focus on fit.

D. So/span> don’t shop first thing in the morning if you often work out in the evening.

E. Pay more attention to new style shoes.

F. Replace worn shoes regularly.

G. Usually they can recommend the best shoes to guard against injuries.

Medical drugs sometimes cause more damage than they cure. One solution to this problem is to put the drugs inside a capsule,protecting them from the body-and the body from them-until they can be released at just the right spot. There are lots of ways to trigger(引发)this release,including changing temperature,acidity,and so on. But triggers can come with their own risks-burns,for example. Now,researchers in California have designed what could be a harmless trigger to date:shining near-infrared light(NIR,近红外线)on the drug in the capsule.

The idea of using light to liberate the drug in the capsule isn't new. Researchers around the globe have developed polymers(聚合物)and other materials that begin to break down when they absorb either ultraviolet(UV,紫外线)or visible light. But tissues also readily absorb UV and visible light,which means the drug release can be triggered only near the skin,where the light can reach the capsule. NIR light largely passes through tissues,so researchers have tried to use it as a trigger. But few compounds(化合物)absorb NIR well and go through chemical changes.

That changed last year when Adah Almutairi,a chemist at the University of Califomia,San Diego,reported that she and her colleagues had designed a polymer that breaks down when it absorbs NIR light. Their polymer used a commercially available NIRabsorbing group called onitrobenzyl(ONB).When they catch the light,ONB groups fall off the polymer,leading to its breakdown. But ONB is only a so-so NIR absorber,and it could be poisonous to cells when it separates from the polymer.

So Almutairi and her colleagues reported /span>creating a new material for capsules that's even better. This one consists of a long chain of compounds called cresol groups linked in a polymer. Cresol contains reactive(易反应的)components that make it highly unstable in its polymeric form,a feature Almutairi and her colleagues use to their advantage. After polymerizing the cresols,they cap each reactive component with a light-absorbing compound called Bhc. When the Bhcs absorb NIR light,the reactive groups are exposed and break the long polymer into two short chains. Shining additional light continues this breakdown,potentially releasing any drugs in the capsule. What's more,Almutairi says,Bhc is 10 times better at absorbing NIR than is ONB and is not poisonous to cells.

D.UV light.

【2】Why is ONB unsatisfactory?

A.It breaks down when it absorbs NIR light.

B.It falls off the polymer and triggers drug release.

C.It has not come onto the market up till now.

D.It is not effective enough and could be poisonous.

【3】Which word can be used to complete the following process of changes?

A. protected

B.formed

C.exposed

【题目】Nicknamed the Golden Music Boy, Hu Yanbin was born and grew up in Shanghai. At the age of 15,he made a that he would make his own album before he was 18. Fortunately, the boy's dream came true.

Some people would this rising star with Jay Chou from Taiwan, but Hu says his musical is quite different from Jay Chou, s, he likes Jay Chou's music.

With many music awards already in his Hu Yanbin seems to be up with many of the superstars in the country. Though some people don't like him and say things about him, he says that it doesn't him. All he plans to do is focusing on his music and bringing out more and better songs for his fans.
