"It's this time of year when the weather starts warming up and frogs start breeding - but they haven't been breeding," says John Wilkinson, research and monitoring officer at the Amphibian and Reptile Conservation Trust (ARC).

Amphibians (两栖动物) are just one of the groups of animals that nature observers fear may have problems reproducing this year, as groundwater levels are even lower now than in the infamously dry summer of 1976, according to the Department for Environment, Food and Rural Affairs (Defra). According to the UK's Centre for Hydrology and Ecology the average rainfall so far this winter has been the lowest since 1972.

"If ponds dry up totally," says Mr. Wilkinson, "you could have lots of dead tadpoles." Drier and windier conditions could also make it more difficult for juvenile amphibians to survive their journeys between wet habitats.

But Peter Brotherton, the biodiversity manager for Natural England, says that "drought is part of nature's cycle", and, at present, a lot of animals, plants and insects are still in hibernation. This means that the population picture is unclear. "However, when we get extreme events, we get animals dying," he says. "And what is worrying is that normally at this time of year we expect soil to be near saturation（湿润）after winter."

Charlie Kitchin, the RSPB's site manager of the Nene Washes in Cambridgeshire, says the 2,000-acre wetland and grassland area is now struggling following two winters with relatively little winter rain and no flooding. One species that could suffer, he says, is the black-tailed godwit（黑尾豫）. "There are only 50 breeding pairs in the country, and we have 40 of them, and everything is bone-dry," Mr Kitchin says.

But one bad nesting season, he says, is "not the end of the world". "One of the features of flood plains is that they're volatile anyway," he adds. "But if they fail to breed another year, the population is likely to dip again."

1.According to the passage animals may have problems reproducing this year mainly due to _____.

2.What really worries Peter Brotherton is that ________.

3.Which of the following is NOT true of Charlie Kitchin’s words?

4.The underlined word volatile in the last paragraph can be replaced by ________.

5.It can be learnt from the text that ______________.

Whether you are racing or touring, long-distance cycling can be very rewarding. 1. In general, it is more important to prepare your mind and your gear (齿轮) for the challenge ahead than it is to train your body. The best way to physically train for a long cycling trip is to take a long cycling trip! There are several steps for you.

Stretch first! Warm up for at least ten minutes before each long-distance cycling session. 2. This way, you can reduce the risk of injury.

Pace yourself. 3. Try to keep up this pace as best you can. Use a lower gear so that you don't wear yourself out. Try to keep up a rate of roughly 90 rpm(revolutions［旋转］per minute) on a low gear to go easy on your muscles and lungs.

Shift gears. When you come to a hill, change into a lower gear so that you can more easily reach the top. 4. Throughout the ride, stay aware of how hard you are working. If you are struggling to push the pedals (踏板), you should switch into a lower gear to conserve your energy.

5. Even if you feel strong, stop every 10-20 miles to give your body a rest and ensure that everything is running smoothly. Rehydrate (补水) by drinking some water, and boost your energy levels with a quick snack. Keep doing so until you arrive at your destination.

A. Take regular breaks.

B. You are sure to face some challenges during your cycling.

C. You should make better use of gears.

D. Try some exercises like jumping and jogging in place.

E. When going down, you should change to a higher gear.

F. It trains your body and provides a chance to appreciate the beauty along the road.

G. Start cycling at a speed which suits you.
