Rain and cold weather this summer saw honey yields from hives(巢)fall by almost three-quarters, the British Beekeepers Association(BBKA)said today. The average crop per hive was down 72% compared to last year, with just 3.6kg (81b) of honey produced compared to an annual average, the annual honey survey by the BBKA revealed.
The survey of 2,712 beekeepers in England, Northern Ireland and Wales found that 88% said this summer’s bad weather caused the descent in honey yields. The bad weather made it difficult for bees to excrete(排泄),which led to disease easily, and the bad weather also increased the risk o
f keeping bees for heavy rain caused the places which bees regularly visited to meet natural disasters. The bad weather also influenced the plants flowering which increased the cost of keeping bees. The BBKA issued a midsummer warning to feed bees if necessary to avoid dying from hunger. But in London, which recorded the worst results with just 2.5kg (5.61b)of honey harvested on average, beekeeping experts said that in addition to the bad weather there was a lack of food for bees in the city.
Angela Woods, secretary of the London Beekeepers Association, said, “Rather than putting beehives on office roofs, we encourage companies in London that want to help to look at different ways of supporting bees and beekeepers. We need more food for the bees and better-educated beekeepers.”
Elsewhere, the weather was the main problem. Peter Hutton, a beekeeper in Tunbridge Wells, Kent, said, “It has been the most difficult year I have known in my 53 years of beekeeping. Bad weather in spring prevented bees in many areas from collecting nectar(花蜜)from early-flowering crops such as oilseed rape(油菜),and the rain continued in many places throughout June and July, preventing honeybees from searching for food on later crops.”
The BBKA warned that as well as reducing the honey harvest, the bad weather is likely to have a longer-term influence as it will have affected the normal process of breeding for t
he queens, which mate(交配)on the wing on fine, still summer days. As a result they may have mated poorly and be unable to produce enough new babies to see groups through the winter.

Cold weather during winter months may keep many people from leaving home and running in the open air.
However, a new study shows that the drop in temperature is a good reason to run. In fact, researchers say, running in cold weather helps improve one’s performance.
Many people say running in the winter can be difficult. Two reasons are the low temperatures and bitter winds. Yet many runners might find it easier than running in hot weather.
That could be because lower temperatures reduce stress on the body. When you run in cold weather, your heart rate and the body’s dehydration (脱水) levels are lower than in warmer conditions. The body needs less water on a cold day than in warm weather.
This information comes from sports scientists at St. Mary’s University in London. John Brewer is a professor of applied sport science at St. Mary’s.
For this study, he and other researchers put a group of people into a room they called an “environmental chamber.” The researchers then recreated summer and winter weather conditions in the room. The test subjects were asked to run 10,000 meters under both conditions. Brewer says he and his team recorded biological measurements of the runners.
“We’ve got a group of subjects into the environmental chamber, we’ve changed the conditions to replicate the summer or winter and we’ve got them to run a 10km under both of those conditions and taken various measurements on each runner while they’ve been completing their 10km.”
Brewer says every movement runners make produces heat. He explains that one way in which we lose heat is by sweating. The body loses heat through droplets of sweat. He says the body also loses heat by transporting the blood to the surface of the skin.
1.What can we know about running in winter?
A. It increases pressure of the body. B. It improves the function of body.
C. It makes your heart rate higher. D. It needs more water than in summer.
2.What can we know about the research according to the text?
A. Researchers interviewed the subjects
B. Subjects were asked to run in winter and summer.
C. Subjects built the “environmental chamber”.
D. Biological measurements of the runners were recorded.
3.Which of the following can replace the underlined word “replicate” in Paragraph 7?
A. Combine. B. Remember.
C. Copy. D. Decorate.
4.What’s the best title for the passage?
A. Environmental Chamber B. The Way of Losing Heat
C. Running in Cold Weather Improves Performance D. Biological Measurements of the Runners

All across California, honeybees are flying away from their hives(蜂箱) and dying. Empty hives are causing a lot of worry about some important food crops.
Bees give us a lot more than delicious honey. They are pollinators（授粉者）—they enable plants to produce the fruits and nuts we enjoy by carrying pollen from one plant or flower to the next. The wind pollinates oats, corn, and wheat, but many other plants (like apple and cherry trees and melon vines) depend on insects, bats, and birds. In the U.S., millions and millions of bees kept by human beekeepers fly around doing a lot of this important work for food crops. “Bees are worth protecting because their work adds so much to our diet,” says Dr. Jeff Pettis of the Bee Research Laboratory.
California’s almond (杏仁) crop alone depends on about half the bees in the country. But now the almond crop and many others could be in trouble with so many bees dying.
Researchers at government and university labs all over the country are trying to figure out why so many bees are dying. However, bees are hard to study. Most die away from the hive, so researchers don’t have dead bodies to examine. And when researchers return to a hive after two weeks, about half the bees they studied on their first visit will be dead, replaced by new ones in the natural life cycle of bees. “It isn’t like studying a large animal like a cow that doesn’t move around much and is easy to find out in the cow field,” says Pettis.
Researchers have some ideas about what could be affecting bee health. They could be sick from poisons widely used to kill insects, or they might not be getting enough good food to stay strong. Also, tiny insects called mites feed on bees. “A virus or bacteria could also be doing the killing.” explains Pettis.
1.What is Paragraph 2 mainly about?
A. The wind helps pollinate.
B. Bees are important in food crops.
C. Bees give us a lot of delicious honey.
D. Cherry trees are pollinated by bees.
2.Bees are hard to study because ____________.
A. they move around too much
B. new bees soon replace all the bees studied by researchers

D. they never return to hives
3.What could cause so many bees to die?
A. Poisons to kill birds. B. Eating too much.
C. Large insects. D. Some virus.
4.What can we learn from the article?
A. A large number of bees have died in the hive.
B. Without bees, some foods would disappear from our diet.
C. Only researchers in California want to know what kills bees.
D. Large animals are easier to study than tiny insects.

When is the best time to exercise and what times will yield the best results?1.This means anytime that our bodies are not feeling exhausted and at least an hour after a meal to allow the enzymes (酶)to break down the food and help the body return to its normal state.
2.However, those who prefer to exercise in the morning but end up feeling bored and worn out, do so because of a lack of sugar in the body.3. If you don’t have time to enjoy a delicious one, just have a couple of biscuits to fill your stomach.
For exercise in the afternoon or evening, it is strongly advised that you do not allow your stomach to start growing after a session of exercise either. The body requires about 2, 000 kilocalories per day, but when exercising, we will burn up to 500 kilocalories extra.4. If we do not refill our energy stores, we are easier to feel cheerless or even exhausted.
For those who do not have the time to exercise properly, it is advisable that you by to use stairs instead of lifts and walk to get your lunch rather than drive. Even though these activities will not burn as many calories as serious exercise, they will ensure that your muscles are working harder than usual.5.
A.That is why eating breakfast is so important.
B.The best time for exercise is different for each person.
C.It’s said that people who work out early are most likely to stick with a routine.
D.The truth is that anytime you are available and prepared to exercise would be okay.
E.When this energy is running out, our bodies will send us a message that food is needed.
F.If these activities then become habits, they will have a positive effect on how well your body energy.
G.Not only will these activities help improve our physical wellbeing, they can increase productivity at work.
