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 won’t 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’s the perfect excuse to sign up for that hip-hop dance class you’ve 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’re short of time or want to get everything you can out of your usual 45-minute workout, try total-body activities such as rowing ormming. You can evenng your arms as hard as you can while you walk.
小题1: 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 faster. |
| D．By forcing your body to work harder. |
| A．Dance. | B．Movement. | C．Body. | D．Muscle. |
| 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. |
答案
小题1:D
小题2:C
小题3:A
解析
小题1:第一段提到“the wet stuff is about 12 to 15 times as resistant (具有阻力的) as air”，因此在水中跑步需更用劲。
小题2:it 代指“Surprising your body with new activities”中的body。
小题3:根据第3部分内容，A正确。

The largest study of the effects of ageing on the heart has found that women’s longevity may be linked to the fact that their hearts do not lose their pumping power with age.
“We have found that the power of the male heart falls by 20-25 percent between 18 and 70 years of age,” said the head of the study, David Goldspink of Liverpool John Moores University in the UK.
“Within the heart there are millions of cells that enable it to beat. Between the age of 20 and 70, one-third of those cells die and are not replaced in men,” said Goldspink. “This is part of the ageing process.”
What surprises scientists is that the female heart sees very little loss of these cells. A healthy 70-year-old woman’s heart could perform almost as well as a 20-year-old one’s.
“This gender difference might just explain why women live longer than men,” said Goldspink. They studied more than 250 healthy men and women between the ages of 18 and 80, focusing on healthy persons to remove the confusing influence of disease. “The team has yet to find why ageing takes a greater loss on the male heart,” said Goldspink.
The good news is that men can improve the health of their heart with regular exercise. Goldspink stressed that women also need regular exercise to prevent their leg muscles becoming smaller and weaker as they age.

| A．health | B．long life | C．ageing | D．effect |

| A．enable your heart to beat much faster |
| B．find out the reason for ageing |
| C．exercise regularly to keep your heart healthy |
| D．prevent your cells from being lost |
| A．the reason why ageing takes a greater loss on the male heart has been found out |
| B．scientists are on the way to finding out why the male heart loses more of the cells |
| C．the team has done something to prevent the male from suffering the greater loss |
| D．women over 70 could lose more heart cells than those at the age of 20 |
