Ways to Burn More Calories

Run through water

Running in water is one of the toughest activities you can perform because the wet stuff is about 12 to 15 times as resistant（具有阻力的）as air．Try your hardest to run and you can burn about 17 calories per minute．

Start fast

Don’t be fooled — slow and steady will not win the race．A recent study found that after a short warm-up，cyclists who rode hard during the first half of their workouts and then slowed for the second half burned about 10 percent more calories than those who started slow and finished fast．

Take to the sand

Here is some easy-to-remember advice on burning calories: the softer the surface，the more you burn．By walking or running on the beach，you can use up 20 to 50 percent more calories than you do going at the same pace on a hard trail．

Shut up and dance

Here is the perfect excuse to sign up for that hip-hop dance class you have been eager to try．Surprising your body with new activities — dance，a new sport，you name it — forces it to work harder because it’s doing unfamiliar movements and using muscle groups in different ways．

Use your arms

Getting both your upper and lower body involved can provide a big calorie-burning advantage．So if you are short of time or want to get everything you can out of your usual 45-minute workout，try total-body activities. You can evenng your arms as hard as you can while you walk．

59．How can water help you burn more calories?

A．By pushing your body． B．By wetting your clothes and shoes．

C．By forcing you to run father． D．By forcing your body to work harder．

60．What does “it” in Part 4 refer to?

A．Dance． B．Movement． C．Body． D．Muscle．

61．Which of the following statements is TRUE?

A．One can burn more calories when walking on the sand than on land．

B．One can burn more calories when walking on stones than on earth．

C．One can burn more calories when running in water than on the sand．

D One can burn more calories when exercising using the upper body than using the lower body．

　　He held the blazing(点燃的)matches to a piece of wood．After a while, he became aware that he could smell his hands burning．Then he began to feel the pain．He opened his hands, and the blazing matches fell onto the snow．The flame went out in a puff of gray smoke．

　　The first person to use the sun's energy on a large scale was the Greek, Archimedes．He used it to set fire to an attacking Roman fleet at Syracuse in 212B．C．He did this by means of a burning glass composed of small square mirrors made to move in all directions on hinges．In the early twentieth century, solar energy was used to power water distillation plants in Chile and irrigation pumps in Egypt．

　　Today over ninety-eight per cent of our energy comes from fossil fuels; coal, oil and natural gas．But coal and oil are not only fuels．They are also important raw materials for our chemical industries．People now think we should limit their use as fuel, otherwise the world's supply will soon run out．Consequently, much research is being done into the practical use of the sun for heating(and cooling)buildings．The less fossil fuel we use now, the more we will have for the future．

　　Solar energy is transmitted from the sun－through space－to earth by electromagnetic radiation．It must be converted to heat before it can be used．Various types of solar energy collectors(also called absorbers or absorber plates)are used to convert the sun's radiation to heat．Solar-heated hot water provides not only the building's hot-water requirements, but space-heating as well．This solar system, based on water-heating, works like this．Each of its collectors, placed on the roof, consists of a shallow fiberglass tray that holds a number of copper tubes under a special glass cover．The tubes are, in turn, fixed to a blackened metal surface which absorbs energy from the sun．The sun's rays, passing through the glass, heat the water in the tubes．

　　Since the energy is available only during the day and only then when there is not a great deal of cloud cover, the heat must be stored．This can be done in water, or in rock or pebble beds．The energy is stored in the hot water in the pipes．

(1)

Solar energy was first used ________．
[　　]
A．	to start a fire
B．	to cook food
C．	to power a heating-system
D．	in a war

(2)

What must be done to solar energy before it can be used?
[　　]
A．	It must be stored in rock beds．
B．	It must be distilled．
C．	It must be converted to heat．
D．	It must be purified．

(3)

There is so much research into the use of solar energy because ' ________．
[　　]
A．	more irrigation projects are needed
B．	the construction industry is expanding
C．	fossil fuels are running out
D．	it transmits electromagnetic radiation

(4)

Solar energy must be stored because ________．
[　　]
A．	it is limited
B．	there is not much of it
C．	it is not always available
D．	the passage does not tell us why

(5)

How many uses has solar energy been put to according to the passage?
[　　]
A．	2．
B．	3．
C．	4．
D．	More than 4．
