1、When it comes to walking off those excesses（过剩）, a lengthy hike once a day will do you far more good than nipping down to（一溜烟跑）

walks add up to the same amount of time, say exercise researchers in Britain. But walks of any length beat sitting at home with your feet up and watching television. They stress.

Some researchers in Britain reached these conclusions after putting 56 couch potatoes through an 18-week course of daily walks.

They found that longer walks produce the most beneficial changes to the composition of blood fats, but walks of any length improve the fitness of the heart.

In the study, the normally inactive subjects were divided into three roughly equal groups. The "long walker" took a hike of between 20 and 40 minutes every day. "Intermediate walkers" had two rounds of jogging of 10 to 15 minutes, and "short walkers" did three stints of 90 to 110 minutes. The controls sat at home, as usual.

At the start and end of the 18 weeks, the health and fitness of each group were measured and it was found that the long walkers were healthiest, as measured by altered fat profiles in their blood.

At the end, each liter of blood from the long walkers contained an average 0.05 grains less apolipoprotein （阿朴脂蛋白）II, a "bad" fat that is linked with heart disease. This was more than twice the drop seen in the intermediate walkers, and five times that in short walkers. In the controls, the level of this fat stayed the same. The drop in apolipoprotein II in the long walker was matched by a rise in the blood level of apolipoprotein I, a "good" fat that is associated with smooth arteries. (1)、According to the researchers, ______ is least beneficial to your health.

A：taking a lengthy hike once a day

(5)、Why is long walk beneficial to our heart?

2、If you have recently started collecting stamps, or are thinking about starting, you may be wondering if the hobby is expensive. Can you enjoy it with limited money? What if you have no money at all for the hobby? The answer is an absolute positive one.

Not all collections consist mainly of unused stamps that you buy in the post office. Used stamps are worth saving, have value, and they may cost you nothing. In fact, many stamp collectors save only used stamps!

The first place to search for stamps, then, is your own mailbox. You can ask people who write to you to use commemorative(纪念性的) stamps on their mail. Also, if you write away for offers that require a self-addressed stamps envelope, you can put commemoratives on your return envelopes, knowing that they will come back to you later. Neighbors, friends, and relatives are another good source of stamps. A majority of people is only too happy to save the stamps on their mail for someone who will appreciate them. You may even know someone who works in an office that gets a lot of mail. Many businesses get a lot of foreign mail and regularly throw away stamps that may have interest or value to a collector. And don't forget to ask your parents if they have any old letters which may still have stamps on the envelopes.

Now that you have stamps on paper, what do you do with them? The most common way to get stamps off paper is to soak them in water, then dry them on paper. To understand more about soaking stamps, it is best to find a handbook on stamp collecting at the library.

Stamp clubs are another place to get stamps. A club may offer stamps as prizes, or have inexpensive stamps you can afford to buy. If you don't have a stamp club around you, try to start one

with a few others. All it takes are four or five other stamp collectors who are interested in getting together to learn about and trade stamps and ideas. Obtaining a pen pal(笔友) in another country is a very good way to get stamps from that country. His or her extra stamps may seem really common in that country, but over here they are much scarcer.
