6．Getting paid to stay in bed all day sounds pretty good．But what if someone offered you $23，000to stay in bed for two months？That's the deal that a medical research team in Toulouse，France，is offering to 24volunteers．Those volunteers must be men between the ages of 20 and 45 who are in perfect health and physically active．
Researchers at MEDES，the Institute of Space Medicine and Physiology，are looking for volunteers to help them study the effects of weightlessness on the human body by spending 60 days lying down．Lying in bed isn't exactly the same as being weightless，but the effects on the human body are similar．
When astronauts spend a long time in an environment with no gravity，like the International Space Station，their bodies are affected in many ways．After a couple of months on the ISS，astronauts'hearts don't beat as hard．Their muscles become smaller and weaker because they no longer have to work against gravity．Their bones may break more easily．There may also be changes in the astronauts'immune（免疫）systems and sleep habits．
Dr．Arnaud Beck，the doctor in charge of the study，said his goal is to measure the effects of weightlessness，and also to find ways to prevent problems．
The study will take 88 days altogether．During the first two weeks，the volunteers will be measured and tested about their levels of fitness and strength．Then they will spend 60days lying in bed with their heads slightly lower than their bodies．
They will have to do everything while lying down，including eating，brushing their teeth，and going to the bathroom．Dr．Beck said the rule is that they must have at least one shoulder touching the bed at all times．
Half of the volunteers in the study will be taking medicine containing special food supplements（补充物）several times a day to see if they help reduce the health problems caused by weightlessness．
The last two weeks of the study will be spent taking more measurements and trying to build up the subjects'strength again．

28．All the volunteers are required toA．
A．be healthy and energetic
B．stay in bed for 88days
C．take medicine several times a day
D．have only one shoulder touching the bed
29．What can we infer from the passage？D
A．Astronauts have to lie in bed when they are in the space station
B．The volunteers will have to do everything while lying down
C．The volunteers will live in an environment with no gravity
D．There are altogether three stages in the study
30．The passage is mainly aboutB．
A．the medical research on lying in bed
B．the medical research on weightlessness
C．the study on astronauts'bodies and health
D．the study on young men's fitness and strength．

20．New research findings show bilingual（able to speak two languages equally well） people are great at saving brain power．To do a task，the brain recruits different networks，or the highways on which different types of information flow，depending on the task to be done．A research team from Montreal，Canada，compared what are known as functional brain connections between seniors who are monolingual （speaking or using only one language） and seniors who are bilingual．The team established that years of bilingualism change how the brain carries out tasks that require concentrating on one piece of information without becoming distracted by other information．This makes the brain more efficient and economical with its resources．
To arrive at this finding，the team asked two groups of seniors （one of monolinguals and one of bilinguals） to perform a task that involved focusing on visual information （the color of an object） while ignoring spatial information （the position of the object）．The researchers compared the networks between different brain areas as people did the task．They found that monolinguals recruited a larger circuit with multiple connections，whereas bilinguals recruited a small circuit that was more appropriate for the required information．These findings were published in the Journal of Neurolinguistics．
"After years of daily practice managing interference between two languages，bilinguals become experts at selecting relevant information and ignoring information that can distract from a task．In this case，bilinguals showed higher connectivity between visual processing areas located at the back of the brain．This area is specialized in detecting the visual characteristics of objects and therefore is specialized in the task used in this study．These data indicate that the bilingual brain is more efficient and economical，as it recruits fewer regions and only specialized regions，"explained Dr．Ansaldo，the head of the team．
Bilinguals therefore have two cognitive （connected with mental processes of understanding） benefits．First，having more centralized and specialized functional connections saves resources compared to the multiple and more diverse brain areas allocated by monolinguals to accomplish the same task．Second，bilinguals achieve the same result by not using the brain's frontal regions，which are vulnerable to aging．This may explain why the brains of bilinguals are better equipped to stave off （to delay sth．） the signs of cognitive aging or dementia （a serious mental disorder caused by brain disease or injury）．
All the benefits of bilingualism have yet to be discovered．

27．According to the passage，which of the following statements is NOT true？B
A．Bilinguals are more efficient and economical with brain resources．
B．Monolinguals do better in focusing on a piece of information while performing a task than bilinguals do．
C．Daily practice of dealing with two languages enables bilinguals to effectively avoid being influenced by irrelevant information．
D．Monolinguals use larger brain areas and more connections when doing a task．
28．The benefits of being bilingual are the following EXCEPTA．
A．Bilingual people are unlikely to develop dementia when they grow old．
B．Bilingual people have the cognitive advantages．
C．Being bilingual is helpful to saving brain resources by using more centralized and specialized functional connections．
D．Bilingual people can accomplish the same task as monolinguals do without using the frontal areas of brain．
29．What is the main purpose of the passage？C
A．To tell readers the differences between bilinguals and monolinguals．
B．To present disadvantages of being monolingual．
C．To tell readers bilingualism can save brain resources．
D．To discuss how to become a bilingual．
30．What type of writing is this text？D
A．An argumentation
B．A news report
C．A descriptive essay
D．A scientific report．
