Teens and preteens who start the school day really early tend to weigh slightly more than those who start later. That’s the finding of a new study of nearly 30, 000 Canadians between the ages of 10 and 18. These data are the latest evidence that starting school too early can harm health.
“We know from earlier studies that when school starts too early, kids can’t get the sleep they need,” says Genevieve Gariepy. She works at Mcgill University in Montreal, Canada. Getting too little sleep can put kids at risk for a number of problems. Sleepy teens are more likely to be overweight, to have trouble concentrating and to struggle in school. They also are at higher risk of feeling depressed, using alcohol or drugs and getting in car accidents.
As an epidemiologist (流行病学家), Gariepy is interested in patterns of disease. She studies teen obesity,or extreme overweight. In this study,she wanted to know how earlier school start times might be linked to weight.
“Overweight and obesity in adolescents is a big problem in North America,” she says. The number of overweight kids has grown over the past 30 years. About one in three U. S. and Canadian teens are now overweight or obese. Kids who don’t sleep enough may be at higher risk. So Gariepy decided to find more about the impact of school start times.
Her team collected start times of 362 Canadian schools and found that among “6 to 10” graders, those who started school earlier tended to be slightly heavier for their height. Every 10-minute delay in school start time was linked, on average, to a slightly lower weight among students who were the same sex, age and height. But it’s not clear that changing school start time would help heavier kids lose weight. To know for sure, researchers would want to compare the same kids before and after changing to a later school start time.
1.What is the function of the first paragraph?
A.To introduce the main topic.
B.To show concern for teenagers
C.To show the importance of the study.
D.To offer advice on school starting time.
2.What does Gariepy want to find out in her research?
A.How to rid adolescents of being overweight.
B.The links between school start times and teen obesity.
C.Why more and more students are becoming obese.
D.The most suitable sleep time for school students.
3.What can we infer about the study of Gariepy and her team?
A.A 10-minute delay is enough. B.Schools may value its conclusion.
C.Its conclusion is reliable. D.More work remains to be done
4.What can be a suitable title of this text?
A.Experts Worry about the Health of Adolescents.
B.Overweight Becomes Common among teenagers.
C.Study Links Weight to School Starting Time.
D.Students Tend to Sleep Less Than Before.

Most female fashion models start their careers(事业)in their late teens and retire in their early 30s, but 96-year-old Alice Pang isn’t an ordinary fashion model. She started modelling at 93.
Alice always liked dressing well and looking elegant, but never actually considered a career in modelling. But her granddaughter always thought she had it in her, so when she saw an online ad for senior models of 65, she sent in Alice’ s pictures and she was chosen for a photo shoot. Never one to back away from a challenge, Pang decided to give it a shot and even though she knew nothing about modelling, she had all the natural qualities to succeed in it. Today, she is recognized as one of the best senior models in Asia, as well as the oldest.
Born in 1923, Alice never dreamed she’ d one day be modelling for high-end fashion brands like Gucci, Ellery or Valentino, let alone at age 96. But her wonderful skin color and excellent posture(姿势)—uncommon qualities for people of her age—make her one of the most sought-after senior models in the business.
Surprisingly, Alice doesn’t credit exercise or a strict diet for her enviable figure and posture. Even though she agrees that exercise helps some people stay in good shape, she doesn’t even have a morning exercise routine, crediting her good genes(基因)instead. She says her skin is white because she’ s seldom exposed to the sun and she has a straight back.
While most people praise her for her active lifestyle and the courage to start a whole new career in her nineties, some say she should dress and act according to her age. She chooses to ignore them, though, saying that her personal happiness is all that counts.
1.What makes Alice Pang a special fashion model?

B.Her being famous worldwide at an old age.

B.is quite fond of competing with others
C.doesn’t do anything she is unfamiliar with
D.often dreams of being a professional model
3.In Alice’ s opinion, her good shape is ________.
A.completely natural B.quite unexpected
C.due to her strict diet D.the result of regular exercise
4.What can be inferred about Alice from the last paragraph?
A.Active as she is, she is rather stubborn.
B.She always turns a deaf ear to others’ opinions.
C.There are different voices on her present lifestyle.
D.She thinks personal happiness comes before modelling.

I had been living with Dino and his family for ten days or so, who lived and worked in the rainforest. They were the “bad guys”, burning much of the western Amazon to tun it into cattle farms. They were also some of the nicest and warmest hosts. They are a family trying to survive in a very tough environment through hard work. Their view and understanding of the problems the Amazon faces are different from mine. I see the Amazon as an extraordinary valuable life that should be treasured and protected at all costs-the world needs it, and we all need it. However, the Dinos see the Amazon as a vast, lasting resource that feeds them. After talking extent win them, I realized their respect for it was as deep as my own: they just saw it very differently.
Cattle farming in the Amazon is perhaps mainly responsible for the fires we are seeing now. It is an industry of cutting forest, burning it and turning it to cattle farms. Fires spread throughout the Amazon every year as a result of that practice. Putting cattle on the land means replacing trees with animals that produce damaging levels of greenhouse gases. This is just about the most stupid thing humans can do.
One morning after a fire, I returned to the land. I felt as though I had seen the blue smoke from those blackened tree trunks that remained upright, which are memorials to human stupidity.
The problems the Amazon faces are perhaps more complex now than ever before, but they are curable. We need to decide where and how we appoint and apply values based on sensible economic models that favor both the farmer and the forest. One of the issues facing the Brazilian Amazon now is a loosening of rules by the current administration which has opened up more land for deforestation(毁林) and burning. This could be disastrous, both for the Amazon and the rest of the world.
1.What does Paragraph 2 mainly talk about?
A.The consequences of cattle farming. B.The main cause of forest fires.
C.The causes of greenhouse gases. D.The importance of cattle farming.
2.How did the author feel when returning to the land after a fire?
A.It helped the author recall his memory about the land.
B.It reminded us of our foolishness of destroying the land.
C.It's not surprising to see the land destroyed by the fire.
D.It's amazing to see the trees keep straight after the fire.
3.Which of the following statements is true?
A.The writer and Dino respected the Amazon equally in different ways.
B.Cattle farming is not to blame for the fires happening in the Amazon.
C.The problems the Amazon faces are more complex and can't be solved.
D.The Dinos are considered to be bad for burning the forest to make a fortune.
4.What should the Brazilian government do to solve the Amazon problems?
A.Prevent the deeds of burning. B.Offer more land.
C.Take stricter measures. D.Appoint economic models.

Do you have trouble getting started in the morning? Do you have problems learning early in the day? If you do, you are not alone, __1._ They learn better at night than they do in the morning.
To investigate when cockroaches(蟑螂) learn best, researchers at Vanderbill University tested the insects for which odor(peppermint 薄荷 or vanilla 香草) they preferred. Most cockroaches preferred the smell of vanilla to that of peppermint at all times. _2._ Therefore, the scientists trained the cockroaches to prefer the peppermint smell by rewarding the insects with a taste of sugar water when they approached a peppermint smell. _3.__
When the cockroaches were trained at night, they remembered the new associations(peppermint=sugar water; vanilla=salt water) for up to 48 hours. However, if the cockroaches were trained in the morning, they quickly forgot which smell went with which water. __4._
So, cockroaches learn better at night than they do in the morning. _5._ Because of this, it is likely that information they gather at night will be more useful to them. These experiments provide some clues about the interactions between body rhythms, learning and memory.
A.When these insects moved toward a vanilla smell, on the other hand, they were punished with a taste of salt.
B.This result thus shows that the time when they were trained decided the effect of their learning.
C.They are often more active and tend to search for food during the night.
D.They were also found to like sugar water, but not salt water.
E.Cockroaches have the same problem!
F.But they prefer warm conditions found within buildings.

The Great Fire of London started in the very early hours of 2 September 1666. In four days it destroyed more than three-quarters of the old city, where most of the houses were wooden and close together. One hundred thousand people became homeless, but only a few lost their lives.
The fire started on Sunday morning in the house of the King's baker(面包师) in Pudding Lane. The baker, with his wife and family, was able to get out through a window in the roof. A strong wind blew the fire from the bakery (面包房) into a small hotel next door. Then it spread quickly into Thames Street. That was the beginning.
By eight o'clock three hundred houses were on fire. On Monday nearly a kilometer of the city was burning along the River Thames. Tuesday was the worst day. The fire destroyed many well-known buildings, old St Paul's and the Guildhall along them.
Samuel Peyps, the famous writer, wrote about the fire. People threw their things into the river. Many poor people stayed in their houses until the last moment. Birds fell out of the air because of the heat.
The fire stopped only when the King finally ordered people to destroy hundreds of buildings in the path of the fire. With nothing left to burn, the fire became weak and finally died out.
After the fire, Christopher Wren, the architect (建筑师), wanted a city with wider streets and fine new houses of stone, In fact, the streets are still narrow, but he did build more than fifty churches, among them the new St Paul's.
The fire caused great pain and loss, but after it London was a better place: a city for the future and not just of the past.
