Riding your bike regularly not only gets you where you want to go faster than on foot, but protects you against a variety of diseases and makes you feel better.

Cycling is good for your health.

Everyday cycling is an effective and enjoyable form of aerobic exercise. This is the type of exercise that is most effective at promoting good health. For example, cycling reduces the risk of serious conditions such as heart disease, high blood pressure, obesity and the most common form of diabetes(糖尿病).

A study suggest that new cyclists covering short distances can reduce their risk of death by as much as 22%. Cycling helps us with weight loss.

Cycling helps to lose weight because it burns the energy supplied by a chocolate bar or a couple of alcoholic drinks in an hour. A 15-minute bike ride to and from work five times a week burns off about 11 pounds of fat in a year. That kind of cycling pattern also meets the Government’s latest target on exercise: we should take part in some physical activity that leaves us out of breath for at least 30 minutes five times a week.

Cycling can improve your mood.

Cycling has positive effects on how we feel too. Proper exercise has been found to reduce levels of depression and stress, improve moods and raise self-respect.

Cycling can help to maintain strength and coordination(协调).

There can also be indirect benefits in terms of reducing injuries from falls, which can lead to serious disability, especially in older people. The strength and coordination that regular cycling brings make them less likely. Physically active older people have much reduced rates of broken bones.

If you are worried about traffic fumes, there may be no need. Cyclists and walkers actually absorb lower levels of pollutants from traffic fumes than car drivers.

I will leave you with my personal bike motto in the hope that it can help you become inspired to go cycling. When it is cold outside, ride faster to warm up; when it is hot outside, ride faster to create a breeze. Happy pedaling! 61. How does the author convince readers of the benefits of cycling? A. By providing an exact figure B. By making comparisons

C. By offering detailed explanations D. By analyzing cause and effect

62. What’s the authors purpose of writing this passage? A. To show why people prefer cycling to driving B. To encourage more people to give bike riding a try C. To confirm what has long been believed about cycling D. To clarify some misunderstanding of fitness and cycling

B

Ohio---Lake Erie, the fourth largest lake of North America’s five Great supplies fresh drinking water to an estimated 11 million people in Ohio, Michigan and South Ontario, Canada.

Yet sometimes pollution, both from industrial waste and farm-chemical runoff, leaves large areas of the lake covered in half-meter-thick layers of green slime(黏液). Scientists blame a lot of chemicals entering the water, which has caused pollution.

To find out where these chemicals come from, the Ohio Department of Natural Resources has been studying data from its network of 14 water-quality monitoring stations installed along the rivers that flow into the Lake Erie basin. At one point, water from the small stream is diverted into pipe where it is pumped into the testing station. “We’ll have a sample a day, year round so that really pins down what the chemistry is like,” says Dave Baker of Ohio’s Heidelberg University, who took charge of the monitoring stations for the Department of Natural Resources. The U.S. Environmental Protection Agency, the federal government’s pollution watchdog, requires point sources, such as factories, to monitor and report their discharges(排出物). So Baker is looking for where the other sources of pollution come from.

“If there are problems in Lake Erie, we want to know where it’s coming from and make sure we’re putting resources to solve the problem properly,” Baker says. “It’s stations like this that help do that.”

In this case, a primary source of the pollution turns out to be chemical fertilizers that wash off farmland during rainstorms.

Because farmers and ranchers believe fertilizers are essential to high crop yields, they would like to use them. However, the USDA’s Natural Resource Conservation Service isn’t asking them to abandon farm chemicals, but rather to use them more sparingly(慎用地) so that they don’t run off the land when it rains.

Another technique for reducing farm chemical pollution of Lake Erie is cover-crop farming. After the harvest, farmers plant a second quick-growing crop to reduce erosion. The deep-rooted plants, such as rye or turnips, help to

cover the soil, allowing worms and fungi to work their magic and helping the soil to absorb more water and nutrients. 63. Who provides data from Lake Erie? A. The water-quality monitoring stations. B. Natural Resource Conservation Service. C. The Ohio Department of Natural Resources. D. The U.S. Environmental Protection Agency.

64. The underlined phrase “pin down” in Paragraph 5 means “___________”. A. looks through B. explains exactly C. keep a record of D. show clearly 65. What causes the pollution in Lake Erie? A. Animal waste from nearby farms. B. Waste water from a nearby factory. C. Chemical fertilizers from the fields. D. Pesticide farmers used to kill locusts.

66. What is the purpose of planting quick-growing crops? A. To prevent worms from eating crops. B. To increase the harvest of the farmers.

C. To make full use of chemical fertilizers in the soil. D. To keep the soil from being washed away.
