“We all know that exercise is good for us, but can you get the benefits without actually doing the exercise?” asks Michael Mosley.
Having a hot bath or a sauna is a good way to soothe your limbs after exercise, but what happens if you do it instead of exercise? Dr. Steve Faulkner of Loughborough University asked me to take part in an experiment comparing the relative benefits of having a long, hot bath versus an hour of hard pedalling.
For this study I join a group of volunteers who have all been fitted with monitors which continuously record blood sugar levels. Keeping your blood sugar levels within the normal range is an important measure of your “metabolic” fitness.
The first part of the experiment is very relaxing, consisting of having a long, hot bath. While I sit in the bath, which they keep at 40℃, Steve closely monitors my core temperature. Once it has risen and stayed there, I am allowed out.
A couple of hours after my bath I have a light meal. Since we want to see how having a hot bath compares with exercise we repeat the experiment.
So what’s the result?
“One of the first things that we were looking at,” Steve says, “is the energy expenditure while you’re in the bath and what we found was an 80% increase in energy expenditure just as a result of sitting in the bath for the course of an hour.”
This is nothing like as many calories as cycling for an hour (which comes out at an average of 630 calories) but we do burn 140 calories, the equivalent of a brisk 30-minute walk.
1.What is the meaning of the underlined word in Paragraph 2?
A. exercise B. strengthen C. relax D. build up
2.What is the purpose of the experiment?
A. To compare energy expenditure of hot bath and pedalling
B. To tell people how to lose weight.
C. To show the benefit of hot bath.
D. To encourage people to have a hot bath instead of pedalling.
3.What does normal sugar level mean?
A. It means you are healthy. B. It means your temperature is normal.
C. It means you don't need exercise. D. It means your metabolic system is normal.
4.If you want to burn 600 calories, what can you do?
A. Have a hot bath for one hour. B. Cycle for one hour.
C. Have a brisk 60-minute walk. D. Have a brisk 30-minute walk.

Some people can stay up all night and still get work done the next day.I'm not one of them.After a night without enough sleep, I feel badtempered.I have trouble remembering things.And all I want to do is to crawl into bed and sleep.
How do you feel after you've stayed up late to finish schoolwork? Or the day after an overnight party? Scientists now say that your answers to these questions may depend on your genes.
New research suggests that a gene called “period 3” affects how well you function without sleep.The “period 3” gene comes in two forms：short and long.Everyone has two copies of the gene.So, you may have two longs, two shorts, or one of each.Your particular combination depends on what your parents passed on to you.
Scientists from the University of Surrey in England studied 24 people who had either two short or two long copies of “period 3”．Study participants had to stay awake 40 hours straight.Then，they took tests that measured how quickly they pushed a button when numbers flashed on screen and how well they could remember lists of numbers.
Results showed that the people with the short form of “period 3” performed much better on these tests than the people with the long form did.In both groups，people performed worst in the early morning.
After the first round of experiments，participants were finally allowed to sleep.People in the group that performed well on the tests (those with the short form of “period 3”) took about 18 minutes to nod off.
People with the long “period 3” gene, by contrast, fell asleep in just 8 minutes.They also spent more time on deep sleep.That suggests that people with the long form of the gene need more and deeper sleep to keep their brains working in top form.
I think I must have the long form of“period 3”．What about you?
1.The purpose of this passage might be________.
A．to tell us the importance of plenty of sleep
B．to tell the result of a research on sleepy gene
C．to inform the harm of lacking sleep
D．to announce the sleeping rules of humans
2.Which of the following decides how well you perform without sleep?
A．One short form.
B．One long copy.
C．One short and two long copies.
D．Period 3.
3.What kind of people need less sleep according to the research?
A．Those with two long copies of the gene.
B．Those with two short copies of the gene.
C．Those with one short and one long copy of the gene.
D．Those with three short copies of the gene.
4.If one lacks enough sleep，one should avoid doing important or dangerous things
________.
A．at dawn B．at night
C．in the afternoon D．at noon
