7.Some colors people see late at night could cause signs of clinical(臨床的)depression (沮喪).That was the finding of a study that builds on earlier study findings.They show that individuals (個(gè)人) who live or work in low levels of light overnight (整夜) can develop clinical depression.Doctors use the word"clinical depression"to describe severe form of depression.Signs may include loss of interest or pleasure in most activities,low energy levels and thoughts of death or suicide.
In the new study,American investigators designed an experiment that exposed hamsters(倉鼠)to different colors.The researchers chose hamsters because they are nocturnal(夜行的),which means they sleep during the day and are active at night.
The animals were separated into four groups.One group of hamsters was kept in the dark during their night-time period.Another group was placed in front of a blue light,a third group slept in front of a white light,while a fourth was put in front of a red light.
After four weeks,the researchers noted how much sugary water the hamsters drank.They found that the most depressed animals drank the least amount of water.
Randy Nelson heads the Department of Neuroscience at Ohio State University.He says animals that slept in blue and white light appeared to be the most depressed."What we saw is that these animals didn't show any sleep uneasiness (不安) at all but they did mess up biological clock genes and they did show depressive sign while if they were in the dim(微弱)red light,they did not."
Randy Nelson notes that photosensitive(感光)cells in the eyes have little to do with eyesight.He says these cells send signals to the area of the brain that controls what has been called the natural sleep-wake cycle.
He says there's a lot of blue in white light.This explains why the blue light and white light hamsters appear to be more depressed than the hamsters seeing red light or darkness.

58.Researchers use hamsters in the experiment becauseD.
A.they are similar to humans in dealing with colors
B.they are easy to observe and study
C.they are sensitive to colors like human beings
D.they are active at night and sleep during the day
59.What sign shows that the hamsters are being depressed?A
A.They drink less sugary water.
B.They don't sleep well.
C.Their eyesight becomes worse.
D.Their energy level becomes low.
60.What can help people who work late at night to avoid being depressed?B
A.Not being exposed to dim red light when using computers.
B.Equipping their computer screens to put it more in the reddish light.
C.Living or working in low levels of light overnight.
D.Going to see doctors of clinical depression regularly for help.

17.Some of the world's most famous musicians recently gathered in Paris and New Orleans to celebrate the first annual International Jazz Day.UNESCO( United Nations Educational,Scientific and Cultural Organization) recently set April 30 as a day to raise awareness of jazz music,its significance,and its potential as a unifying(聯(lián)合) voice across cultures.
Despite the celebrations,though,in the U.S.the jazz audience continues to shrink and grow older,and the music has failed to connect with younger generations.
It's Jason Moran's job to help change that.As the Kennedy Center's artistic adviser for jazz,Moran hopes to widen the audience for jazz,make the music more accessible,and preserve its history and culture.
"Jazz seems like it's not really a part of the American appetite,"Moran tells National Public Radio's reporter Neal Conan."What I'm hoping to accomplish is that my generation and younger start to reconsider and understand that jazz is not black and write anymore.It's actually color,and it's actually digital."
Moran says one of the problems with jazz today is that the entertainment aspect of the music has been lost."The music can't be presented today the way it was in 1908 or 1958.It has to continue to move,because the way the world works is not the same,"says Moran.
Last year,Moran worked on a project that arranged Fats Waller's music for a dance party,"Just
to kind of put it back in the mind that Waller is dance music as much as it is concert music,"says Moran."For me,it's the recontextualization.In music,where does the emotion(情感) lie?Are we,as humans,gaining any insight(感悟) on how to talk about ourselves and how something as abstract as a Charlie Parker record gets us into a dialogue about our emotions and our thoughts?Sometimes we lose sight that the music has a wider context,"says Moran,"so I want to continue those dialogues.
Those are the things I want to foster."

28.Why did UNESCO set April 30as International Jazz Day?C
A.To remember the birth of jazz.
B.To encourage people to study music.
C.To recognize the value of jazz.
D.To protect cultural diversity.
29.What does the underlined word"that"in paragraph 3refer to?C
A.The jazz audience becoming larger.
B.The production of jazz growing faster.
C.Jazz being less popular with the young.
D.Jazz becoming more accessible.
30.What can we infer about Moran's opinion on jazz?A
A.It should keep up with the times.
B.It remains black and white.
C.It will disappear gradually.
D.It changes every 50 years.
31.Which of the following can be the best title for the text?D
A.Celebrating the Jazz Day.
B.The Rise and Fall of Jazz.
C.The Story of a Jazz Musician.
D.Exploring the Future of Jazz.

18.With limited space for parks and gardens,architects and city planners often find it challenging to include greenery in neighborhoods in cities.One creative solution is to grow plants on unused areas like walls and rooftops.It's a popular idea,and now rooftop gardens and green walls have been sprouting up(大量冒出)in cities around the world.
There are many benefits of having green spaces to the urban landscape.Adding gardens to rooftops or walls can create a pleasant environment--what was once a gray cement(水泥)wall can become a colorful,blooming garden.The CaxiaForum art gallery in Madrid,Spain,is a famous example--one of its walls is covered with 15,000 plants from over 250 different species.In other cities,green walls are being used more functionally,to cover up construction sites and empty buildings and to decorate the lobbies of office buildings.
Using plants to cover walls and rooftops can also keep cities cooler in the summer.Buildings and roads absorb the sun's heat and hold it,causing a building or neighborhood to stay warmer longer.Plants,on the other hand,provide an enormous amount of shade.There is evidence that growing a roof or wall garden can lower a building's energy costs.
In New York City,public schools plant rooftop gardens that can reduce heating and cooling costs.In addition to saving the school money,teachers and parents love the gardens because of their educational value--it's a fun and healthy way for their kids to investigate the world around them."For the children,it's exciting when you grow something edible(可食用的),"said Lauren Fontana,principal of a New York public school.
Rooftop gardens and green walls may require a bit more effort to grow and maintain.However,hard work always brings rewards,and with green spaces,the rewards are plentiful.
Due to the limited space in cities,rooftop gardens and green walls have emerged.(要點(diǎn)1)One benefit of adding green to rooftops and walls is to offer an agreeable surroundings.(要點(diǎn)2)Besides,shade can be created to make cities stay cooler longer,thus reducing the costs in energy.(要點(diǎn)3)What's more,green gardens in school bear educational value of children's exploring the world.(要點(diǎn)4)Though hard to maintain,green spaces in cities ensure abundant rewards.(要點(diǎn)5)

19.A mystery woman said today she has won£1.5 million from the UK National Lottery-but has never told her husband.
For the past three years,the woman,a mother-of-two who gave her name as Jane,had hidden her fortune from colleagues,friends and family,she said.
"Jane"has remained in her job and,if she ever splashed out on treats for the family,tells her husband she has had a pay rise or bonus.
The woman told her extraordinary story on BBC Radio Five Live this morning.

She continued,"I do feel if I had said,yes,I've won this money,that he would have wanted holiday,he perhaps would have wanted to give up work,which would destroy our little family unit we've got now."
The presenter told her,"I'm very surprised,I can barely believe it but it's clearly true.Do you feel it's made you happier?"
"Jane",who said her won was"about three years ago",said,"It's nice because I know I haven't got to worry about bills."
Derbyshire told her,"I'm full of admiration for you,but is it not a betrayal of your relationship?"
The woman admitted,"I feel terribly guilty in one way,but in another way,we've got two young children and I think,well,if their lives change dramatically then it's not fair on them.So I just want to keep things as they are."
