Arbor Day: Day of Trees
Nebraska was covered with few trees many years ago. The pioneers had trouble in getting enough to build houses. There was no shade from the sun or wind, and crops (庄稼) didn't grow well in the dry earth. So the idea for Arbor Day formed there.
Fortunately, among those moving into Nebraska in 1854 was J. Sterling Morton. He and his wife were nature lovers, and the home they built in Nebraska was quickly planted with trees and flowers. Morton was a reporter of Nebraska's first newspaper, then he became a member of the Nebraska State Board of Agriculture (农业委员会).
On January 4, 1872, Morton first proposed (提议) a tree-planting holiday to be called "Arbor Day" at a meeting of the State Board of Agriculture. The date was set for April 10, 1872. It was estimated (估计) that more than one million trees were planted in Nebraska on the first Arbor Day.
In the years following the Arbor Day, his ideas spread to Kansas, Tennessee, Minnesota and Ohio. Today all 50 states have their own Day of Trees in keeping with local weather.
Hawaii celebrates it in November, while Alaska in May! More interesting, each state has a special "state tree". The "state tree" for Nebraska is cottonwood, for Alaska is Sitka Spruce.
Arbor Day is of American origin (起源) and the idea has spread widely to other lands where it is observed as the "Greening Week" of Japan, "The New Year's Days of Trees" in Israel, "The tree-loving Week" of Korea, and "The National Festival of Tree Planting" in India. Arbor Day in its various forms is now recognized in more than fifty countries. China spends "Tree-planting Day" on March 12.
We have known a lot about Arbor Day. So we should get into action and ask as many people as possible to gather and recycle paper. Then we can use what we earn from the waste paper to buy a special tree to plant in a park or other public places. It is an act of kindness, a labor of love and a duty as citizens. Anyone can do it.

Sleep and Weight
A couple of groups of researchers have found the reason why people are getting fatter. Researchers from the University of Chicago recruited (征募) 12 young men who came to their sleep lab on four different nights. Two nights, the men slept only four hours. The other two nights, they slept ten hours. Researchers Van Carter headed the study.
"After two nights of either short sleep or long sleep, we checked in their blood every 20 minutes or 30 minutes the levels of the hormone stimulating appetite (刺激食欲)."
They also checked the hormone that signals the brain when you're full. They found that when the men slept 10 hours, they woke up with normal levels of hormone and normal appetite. But when they slept only four hours, they had higher levels of hormone that stimulates appetite and lower levels of the hormone that signals fullness.
"Yeah, our study suggests that short sleep does modify the hormone that controls appetite in such a way that one is hungrier."
And not only were the men hungry, but also what they wanted to eat wasn't nutritious (有营养的).
"The foods that they preferred were candy, cookies, cake, ice cream, potato chips, pretzels, bread, pasta, rice, all high carbohydrate (碳水化合物) food."
Another study came to similar results. Researchers at Stanford University analyzed (分析) data from over 1, 000 volunteers who answered questions about sleep habits and also had their hormone levels measured. Psychiatrist (精神病专家) Emmmanuel Meno saw the same increase in the hormone stimulating appetite, and the same decrease (降低) in hormone that signals fullness.
"What's interesting about it is that it's counter-intuitive (反直觉的), because most people would say, 'Oh, yes. If you sleep a lot, you are lazy and you're going to be overweight.' and actually that's not what we observe (观察)."
Over the past forty years, American adults have cut down their average sleep time. They slept about eight and a half hours. Today, it's down to seven or less. Meno says Americans might want to reconsider (重新考虑) the amount of time they sleep.
"Now I think what we are finding is that it's important to sleep the right amount, and healthy sleep is as important as exercise and nutrition. I think, indeed, people who are overweight should sleep a little more. But if they treat better their sleep, it may help them to lose weight."
1.According to the passage, the researchers find that ________.

C.have no sense of sleep and keep awake all the night
D.have high blood pressure and result as a bad headache
3.What does the underlined word "modify" mean in the passage?

4.What can we infer from the passage?

D.Americans are facing the problem of getting overweight at present.
At present, we can use computers or smart phones to text messages to the friends around the world. We can buy fruit from Brazil or see movies made in India on the websites. But how can we get to know and understand people who are living in different countries better?
As we all know, it is beneficial for teenagers to have more knowledge and understand the world better. We must remember that they are the decision-makers of the future. To shape the world in the interests of all, we should help them to act as responsible global citizens (公民). So it is important for them to learn more about how other people live in different parts of the world. By doing this, they can find out what problems they have in their communities and decide how they can help each other better.
A charity (慈善) group in the UK started a project for Africa in February, 2004. The aim of the project was to take a fresh look at Africa's past and present and the international community's role in its development. Lots of British students took part in the project. Students from 25 UK schools connected with students from 25 African schools to discuss the African Continent (非洲) and its culture on the Internet. Some students from the poor areas in Africa were taken to the places that had computers, so they could take part in the project. Students used their computers to work on the Internet and send emails. They could even design their own web pages with pictures, sounds and videos. Together the teenagers built a website which went live in June, 2005. Through the project teenagers were encouraged to study the different cultures of Africa as well as some of the problems facing young people in Africa.
Now, more and more projects have been started since then all around the world. Teenagers from schools in different countries are still trying to make connections and find out more about each other. Let's hope these projects help teenagers understand more about the lives of others on the other side of the world.
