Moreover, it reveals how a low-calorie diet, the only known method of slowing aging in several animal species, works at the most basic level to extend life span and preserve health. Such knowledge, used in concert with new technologies capable of rapidly surveying the activity of thousands of genes at once, premises to accelerate the development of drugs that mimic the age-retarding effects of a low-calorie diet, according to the Wisconsin scientists.

[不定项选择题]共用题干 Toads are Arthritic and in Pain

Arthritis（关节炎）is an illness that can cause pain and swelling in your bones. Toads（蟾蜍）,a big problem
'in the north of Australia,are suffering from painful arthritis in their legs and backbone,a new stu街has shown.
The toads that jump the fastest are more likely to be larger and to have longer legs.______(46)
The large yellow toads,native to South and Central America,were introduced into the north-eastern Aus-
tralian state of Queensland in 1935 in an attempt to stop beetles and other insects from destroying sugarcane
crops.Now up to 200 million of the poisonous toads exist in the country,and they are rapidly spreading
through the state of Northern Territory at a rate of up to 60 km a year. The toads can now be found across
more than one million square kilometres.________(47)A Venezuelan poison virus was tried in the 1990s
but had to be abandoned after it was found to also kill native frog species.
The toads have severely affected ecosystems in Australia. Ariinials,arid sometimes pets,that eat the toads die im-
mediately from their poison,and the toads themselves eat anything they can fit inside their mouth._________(48)
A co-author of the new study,Rick Shine,a professor at the University of Sydney,says that little atten-
tion has been given to the problems that toads face.Rick and his colleagues studied nearly 500 toads from
Queensland and the Northern Territory and found that those in the latter state were very different.They were
active,sprinting down roads and breeding quickly.
According to the results of the study,the fastest toads travel nearly one kilometre a night._________(49)
But speed and strength come at a price一arthritis of the legs and backbone due to constant pressure placed on
them.
In laboratory tests,the researchers found that after about 15 minutes of hopping,arthritic toads would
travel less distance with each hop（跳跃）.________
(50)These toads are so programmed to move,
apparently,that even when in pain the toads travelled as fast and as far as the healthy ones,continuing their
constant march across the landscape. __________(50)
A.Toads are not built to be road runners一they are built to sit around ponds and wet areas.
B.The task now facing the country is how to remove the toads.
C.Furthermore,they soon take over the natural habitats of Australia's native species.
D.Toads with longer legs move faster and travel longer distances,while the others are being left behind.
E.But this advantage also has a big drawback一up to 10%of the biggest toads suffer from arthritis.
F.But arthritis didn't slow down toads outside the laboratory,the researchers found.
