9、earchers at the University of Bristol have discovered that the 24hour rhythms of plants leave them more defenseless to herbicides (除草剂) at different points in their daily 24 hour cycleThey believe the findings could help farmers by reducing crop loss and improving harvests And gardeners could benefi
10、t from knowing which weeds respond better at certain times of the day In recent years, pesticides and herbicides have been implicated in the decline of important pollinating insects, such as beesDr Antony Dodd, senior author of the new study, said, The research suggests that, in future, we might be
11、able to improve the use of some chemicals that are used in agriculture by taking advantage of the biological clock in plantsJust like humans, plants have evolved to take advantage of cycles of night and day, with certain biological processes turning on at different times of the day Scientists have d
12、iscovered that many drugs work much better in humans if they are given at specific hours Aspirin, for example, has doubled the impact on thinning the blood if taken at night as opposed to in the morning The process is known as chronotherapy (时间疗法) and researchers wanted to find out if the same conce
13、pt could be applied to plantsMany gardeners already know that plants drink in more water in the morning because their pores (气孔) are open to take advantage of early morning dew and water vapour At the break of he day, plants are also not busy producing food through photosynthesis (光和作用) The open por
14、es could also be the reasons that chemicals are more effective at dawn and also at duskThe air is also likely to be stiller at dawn and dusk, meaning that pesticides or herbicides are less likely to be blown away to places where they are not wanted Pesticide labels often warn against spraying on win
15、dy days in case they endanger people or animals Many insects are active early in the morning and around dusk, also making very early morning and early evening effective times for insecticideCommenting on the study, Dr Trevor Dines, Botanical Specialist at the conservation charity Plantlife, said, Th
16、is is fascinating research which will be of great interest to many gardeners like me If anything they used to think the opposite was true that applying herbicides and pesticides late in the day would be better as theyd remain in wet contact with the plant for longer in the cool of the night and ther

18、using herbicides in the morning?A.The process of photosynthesis is most active in the morningB.Insects are more defenseless in the morning than any other time of the dayC.Bigger pores on the plants make herbicides work more effectivelyD.The stronger morning wind blows pesticides away to more places2
19、3.What is the main idea of this article?A.New chemicals have been found to help kill harmful insectsB.Biological clock of plants could help gardeners use less weed killerC.Plants cycles can be taken advantage of to improve the environmentD.The research on the effects of pesticides has enabled good h
20、arvestsB In some places around the world, you can find bright green balls of moss ( 苔藓 ) scattered across glaciers, which, surprisingly, move all at about the same speeds and in the same directions.The glacier moss balls are commonly called “glacier mice”, and were the subject of a recent study publ
21、ished online in Polar Biology this month. The studys authors believe that they develop from impurities ( 杂质 ) on ice surfaces. “Theyre not attached ( 黏附 ) to anything and theyre just resting there on ice,” said one of the authors. “Theyre bright green in a world of white.”The moss balls dont stay at
22、 rest for long, though. They moved about 2.5 centimeters per day on average. Another one of the studys authors pointed out that movement is a necessity for the glacier moss balls because the entire surface of the ball must occasionally get exposed to the sun. “These things must actually roll around
23、or else that moss on the bottom would die,” she said.Glacier mice have ever been spotted in Alaska, Iceland, Svalbard and South America, but scientists still have a lot to learn about them.One of the biggest questions is why the moss balls, which can live for at least six years, move the way they do
24、. The researchers tried to explain this strange phenomenon in many ways.First, they thought the balls had rolled downhill, but later found that they werent going down a slope ( 斜坡 ). Then, they thought the wind was blowing them in consistent directions. But when they measured the dominant direction
25、of the wind, that didnt explain it either. And finally, they considered the sun, which melts the ice and may make the moss balls move, but the direction of incoming solar radiation wasnt in the direction which the balls were going in. Still confused with this problem, the researchers said that they
26、hope that one day, future generations will “get to the bottom of these great mysteries”.24.What interests the researchers most?A.The discovery of glacier mice.B.The development of impurities.C.The distribution of glacier moss.D.The movement of glacier moss balls.25.Which of the following is TRUE abo
27、ut Glacier mice?A.They can move fast.B.They are attached to ice.C.They move so as to keep alive.D.They move from other places to glaciers.26.How does the author explain the unusual way the glacier mice move?A.By drawing maps and making analysis.B.By making assumptions and doing research.C.By doing e
28、xperiments and presenting reports.D.By making comparison and setting down general rules27.What can we infer from the last paragraph?A.Wind blows Glacier mice to move.B.The direction of sunlight helps Glacier mice.C.Scientists leave these mysteries to future generations.D.It remains a puzzle why the
29、glacier moss balls move in this way.CWhen life gives you pineapplesand hundreds of millions of tons of pineapple wastewhat do you do? Engineers in Singapore and Vietnam decided to tum all the waste into something usefulthe heat barrier for their pineapple juice. Not only does their new material keep
30、 drinks cool better than many commercial coolers, but it could also offer a final resting place for the worlds pineapple waste.To find a use for those leftovers, the researchers mixed pineapple fibers, which they cut up in an electric device, with a sticky agent as a solvent. They then treated the m
31、ix with sound waves at frequencies greater than 20 kHz and heated it in an oven at 80 for 2 hours. The suspension that formed was then cooled before being freeze-dried.The result was a pale yellow aerogel (气凝胶) that is lightweight, flexible, and more than 96% porous (多孔的)qualities that make it an id
32、eal material against both heat and sound.When the researchers wrapped a sheet of the pineapple aerogel around a military-style canteen bottle, they found that the aerogel could provide three times the heat exchange reduction of commercially available alternativesthey reported this month in Materials
33、 Chemistry and Physics. The gel-wrapped bottle kept -3 water cooled below 0 for 6 hours and liquid heated to 90 above 40 for 2.5 hours. Whats more, the pineapple gel also acted as a sound barrier; in another test, the gel did a better job of preventing noise from getting in or out than Basmel, a pop
34、ular kind of sound barrier.The findings provide a new, eco-friendly approach to recycling agricultural cast-offsand a good excuse to get a better electric device for your kitchen.28.Why do engineers come up with the idea of the heat barrier?A.To lower the cost of heat barriers.B.To make good use of
35、pineapple waste.C.To find a better cooler for pineapple juice.D.To turn pineapples into something more useful.29.What is the last step of making the pineapple aerogel?A.Freeze-drying the suspension.B.Cooling the formed suspension.C.Cutting up the pineapple leftovers.D.Treating the mix with sound wav
36、es.30.What can we learn about the pineapple aerogel from paragraph 4?A.It kept the liquid heated to 130 for about 2.5 hours.B.It kept the water cooled below -3 for nearly 6 hours.C.It could be three times as effective as other heat barriers.D.It did a better job as a sound barrier than as a heat bar
