题目内容

I’m part of the Roots & Shoots program founded by Dr. Jane Goodall. The program is intended to make and promote positive changes in the world. As Dr. Goodall says, “What you do makes a difference, and you have to decide what kind of difference you want to make.”

In Bulgaria, where I live, homeless dogs are everywhere. Many people here turn a blind eye to them. But I cannot ignore the life of a street dog whenever I see one wandering in the street, looking for something to eat. That’s why I’m no longer a food waster. When I see wasted food, I always think of a hungry dog climbing to garbage bins, searching for food that people have thrown there. When eating in a restaurant, I’m not afraid to take leftover food to feed stray cats or dogs.

A week ago, I saw a homeless dog around the garbage bins. Immediately I knelt down, spoke to her softly and ran my hands over her. I could see that she had had puppies. I couldn’t imagine how she could have been able to care for them. Hours earlier, I’d bagged up a plate of leftover fish. As I unwrapped it, she wagged her tail and sniffed at it. She ate all the fish in no time.

It’s sad, isn’t it? I can’t understand why many of us waste so much and think little of it. These homeless animals have taught me that food is precious. Even when I don’t have leftovers with me, I’ll take the time to get something from the grocery store to feed them.

I know my power is small, so I hope that next time you see wasted food, do turn it into worthy food. You have the power to save a life!

14.What will people die of 100years from now?If you think that is a simple question,you have not been paying attention to the revolution that is taking place in bio-technology(生物技术).With the help of new medicine,the human body wll last a very long time.Death will come mainly from accidents,murder and war.Today's leading killers,such as heart disease,cancer,and aging itself,will become distant memories.
In discussion of technological changes,the Internet ets most of the attention these days.But the change in medicine can be the real technological event of our times.How long can humans live?Human brains were known to decide the final death.Cells(细胞) are the basic units of all living things,and until recently,scientists were sure that the life of cells could not go much beyond l20years because the basic materials of cells,such as those of brain cells,would not last forever.But the upper limits will be broken by new medicine.So sometime between 2050and 2100,medicine will have advanced to the point at which every 10years or so,people will be able to take medicine to repair their organs.The medicine,made up of the basic building materials of life,will build new brain cells,heart cells,and so on-in much the same way our bodies make new skin cells to take the place of old ones.
It is exciting to imagine that the advance in technology may be changing the most basic condition of human existence,but many technical problems still must be cleared up on the way to this wonderful future.
24.According to the passage,human death is now mainly caused byB
A.accidents and war                  
B.diseases and aging
C.accidents and aging                 
D.heart disease and war
25.In the author's opinion,today's most important advance in technology lies inC.
A.brain cells    
B.the Internet      
C.medicine      
D.human organ
26.Humans may live longer in the future becauseA.
A.human organs can be repaired by new medicine
B.human brains can decide the final death
C.the basic materials of cells will last forever
D.heart disease will be far away from us
27.We can learn from the passage thatD.
A.human life will not last more than 120years in the future
B.humans have to take medicine to build new skin cells now
C.we have already solved the technical problems in building new cells
D.much needs to be done before humans can have a longer life.

On May 23, 1989, Stefania Follini came out from a cave at Carlsbad, New Mexico. She hadn’t seen the sun for eighteen and a half weeks. Stefania was in a research program, and the scientists in the program were studying body rhythms. In this experiment Stefania had spent 130days in a cave, 30 feet in depth.

During her time in the cave, Stefania had been completely alone except for two white mice. Her living place had been very comfortable, but there had been nothing to tell her the time. She’d had no clocks or watches, no television or radio. There had been no natural light and the temperature had always been kept at 21℃.

The results were very interesting. Stefania had been in the cave for over four months, but she thought she had been there for only two. Her body clock had changed. She hadn’t kept to a 24-hour day, she had stayed awake for 20~25 hours and then had slept for 10 hours. She had eaten fewer meals and had lost 171bs in weight as a result! She had also become rather depressed.

How had she spent her time in the cave? As part of the experiment she’d done some physical and mental tests. She’d recorded her daily activities and the results of the tests on a computer. This computer had been specially programmed for the project. Whenever she was free, she’d played cards, read books and listened to music. She’d also learned French from tapes.

The experiment showed that our body clocks are affected by light and temperature. For example, the pattern of day and night makes us wake up and go to sleep. However, people are affected in different ways. Some people wake up naturally at 5:00 a.m., but others don’t start to wake up till 9:00 or 10:00 a.m. This affects the whole daily rhythm. As a result the early risers are at their best in the late morning. The late risers, on the other hand, are tired during the day and only come to life in the afternoon or evening!

1.Stefania stayed in the cave for a long time because ________.

A. she was asked to do research on mice

B. she wanted to experience loneliness

C. she was the subject of a study

D. she needed to record her life

2.What is a cause for the change of Stefania’s body clock?

A. Eating fewer meals. B. Having more hours of sheep.

C. Lacking physical exercise. D. Getting no natural light.

3.This passage mainly tells about ________.

A. an experiment and its result B. a woman living in the cave

C. a depressed woman D. a woman and two mice

1.Most evenings,before watching late-night comedy or reading emails on his phone,Matt Nicoletti puts on a pair of orange-colored glasses that he bought for S8on the Internet.
"My girlfriend thinks I look ridiculous in them,"he said.But Mr.Nicoletti,a 30-year-old consultant in Denver,insists that the glasses,which can block certain wavelengths of light emitted by electronic screens,make it easier to sleep.
Studies have shown that such light,especially from the blue part of the spectrum (光谱),inhibits the body's production of melatonin(褪黑激素),which helps people fall asleep.Options arc growing for blocking blue light,though experts caution that few have been adequately tested for effectiveness and the best solution remains avoiding brightly lit electronics at night.
A Swiss study of 13teenage boys,published in August in The Journal of Adolescent Health.showed that when the boys wore orange-colored glasses,also known as'blue blockers'and shown to prevent melatonin,in the evening for a week,they felt"significantly more sleepy"than when they wore clear glasses.The boys looked at their screens,as teenagers tend to do,for at least a few hours on average before going to bed,and were monitored in the lab.
Older adults may be less affected by blue light,experts say,but blue light remains a problem for most people,and an earlier study of 20adults aged 18to 68found that those who wore orange-colored glasses for three hours before bed improved their sleep quality considerably relative to a control group that wore yellow-colored lenses,which blocked only ultraviolet(紫外线)light.
LEDs used in devices such as smart phones,tablets and televisions tend to emit more blue light than incandescent products(白炽产品).LEDs are also increasingly popular as room lights,but"warm white"bulbs,with less blue,tend to be a better choice than"cool white"for nighttime use.The lighting company Philips also makes a reduced-blue LED bulb,meant to be used妙fore bedtime."In theory,anything that will decrease that blue light exposure at night will be helpful."said Christopher Colwell,a scientist at the UCLA,"I know some gainers who swear by those orange-colored glasses."
But orange glasses are not a panacea(万能药).Dr.Skene said."It isn't just getting rid of the blue and everything's fine,"she said.The intensity of light,in addition to color,can affect sleep,she said,and not all brands of orange-colored glasses have undergone enough independent testing for their ability to aid sleep.
During the daytime,experts say,exposure to blue light is good.Best of all is sunlight,which contains many different wavelengths of light."That's what our brain knows,"said Kenneth P.Wright Jr.,director of the sleep and chronobiology(生物钟学)lab at the University of Colorado,Boulder.
A 2013study he led,published in the journal Current Biology,showed just how different things can be without nighttime lights.After participants had camped in the mountains for a week,their bodies began to prepare for sleep about two hours earlier than normal.
Short of cutting out all evening electronics,experts say,it's advisable to use a small screen rather than a large one; dim the screen and keep it as far away from the eyes as possible; and reduce the amount of time spent reading the device.
"If you can look at the iPhone for 10minutes rather than three hours,that makes a lot of difference,"Dr.Skene said.
