I have recently completed my college degree. The last project was called “Smile”. The class was asked to go out to smile at three people and document their reactions（反应）. I am a very friendly person and always smile at everyone and say hello anyway. So, I thought this would be a piece of cake.
My husband, the youngest son and I went out to McDonald. We were standing in line when all of a sudden everyone around us began to back away. As I turned around I smelled a horrible body odour（气味） and saw two poor homeless men standing behind me. As I looked at the short blue-eyed gentleman closest to me, he was “smiling”. The second man fumbled（摸索）with his hands as he stood behind his friend.
The young lady at the counter asked him what they wanted. He said, “Coffee is all, Miss,” because that was all they could afford.
Then I really felt it — I embraced（拥抱）the little man with the blue eyes. That is when I noticed   all eyes in the restaurant were set on me, judging my every action. I smiled and asked two more breakfast meals on and gave them to the men.
The blue-eyed gentleman looked up at me, with tears in his eyes, and said, “Thank you.”
I turned in my project. My teacher said, “Can I share this?” I slowly nodded as she got the attention of the class. She began to read and that is when I knew that we as human beings share this need to heal people and to be healed.
In my own way I had touched the people at McDonald’s and every soul that heard the story in the classroom. But, I graduated with one of the biggest lessons I would ever learn.
【小题1】 The underlined part “a piece of cake” in Paragraph 1 means _______.

Dr. Julie Coulton, a British psychologist, focuses her research on the extraordinary function of the play in the physical and spiritual development of children and Martti Bergson from the University of Helsinki shows that playing outside, in the open air, contributes to a better development of the brain.
Thus parents must encourage their children to spend as much time as possible in the open air, and at the same time, to ask schools and kindergartens to assure the small a playground outside. Recent statistics (数据) and studies show an alarming increase of the number of hours spent by children in front of the TV and the computer and a decrease of the time spent outside.
As a consequence more and more children suffer from eye problems and have to wear glasses. Also the problem of fatness among children concerns many parents who don't know what to do anymore to make their children eat healthy and balanced.
Children need a space where to develop their creativity mid parents should encourage them all the time. Too many rules hold back the child's personality and creativity and prevent them to develop the desire to know, to find out, to learn.
If you tell your child so many times: "Don't do that, don't mess the room, don't go there ...", he will lose the desire to do something, anything. Parents must watch their children without suffocating (窒息) them. Should you consider they mustn't do that or this, you have to logically explain them your reasons and they will understand.
Through playing a child learns how to communicate, how to take decisions. Playing is connected to the intellectual, emotional and social progress of the child. Playing lets your children learn how to express his feelings.
【小题1】What is worrying the scientists is that ______.

When people want to know about the weather,they usually go to their radios,TVs, newspapers,or to the Internet.However,you can also find many weather signs among wildlife, because of their highly developed senses.Drops in air pressure(压力) produce an effect on small animals in many ways.Mice and deer are good weather indicators.People who spend a lot of time outdoors have observed that,before a storm,field mice come out of their holes and run around.Deer leave high ground and come down from the mountains.
Birds are especially good weather indicators because they also show the effect of a pressure drop in many ways.For example,some birds become irritable(急躁的) and quarrelsome and will fight over a piece of bread.Other birds chirp(叽叽喳喳) and sing just before a storm.It seems they know they won’t get another chance for an hour or two.Birds also seek safe places before a storm.You will sometimes see birds settling in trees or gathering together on a wire close to a building.Pre-storm low pressure makes the air so thin that birds have difficulty flying.
It is unusual to see many birds flying overhead in the summertime,rather than during the periods in the spring or autumn.Watch for other weather signs if you see this.If they fly in the wrong direction,they may be flying ahead of a storm.
By paying closer attention to some important signs in nature,we can become better prepared for any kind of weather.
【小题1】The word “indicators” in Paragraph 1 probably means______.

Rowena and Billy Wrangler are model high school students. They study hard and do extremely well on achievement tests. And next year，Rowena will be attending Harvard University．Billy，her younger brother，hopes to go to Cornell．What makes Rowena and Billy different from most students is that they don't go to school．In fact，they've never been to school．Since kindergarten，they've studied at home．Like many of more than one million people who receive home schooling in the United States, they feel as if they've gotten a good education．
The home-schooling trend began in the U.S．in the 1980s with parents keeping their children out of public schools so they could provide religious education at home. Today，as the home-schooling trend continues to grow，parents are more likely to consider home schooling as an option because they believe schools don't do a very good job of teaching and are occasionally dangerous places．But can parents really do a better job?
The answer in many cases is yes．In many studies，students taught at home ranked average or above average when compared to students who went to public schools．More importantly，these students were often more self-directed and have a greater depth of knowledge．They were well prepared for academic challenges．
One such student，Robert Conrad, now a sophomore at university, claims he really learned how to study and schedule his time during his eight years of home schooling．Still, not every student is as successful as Robert．
“For every home-schooling success story，there are an equal number of failures．”states Henry Lipscomb，an educational researcher．“There are just so many disadvantages that students taught at home have to overcome.” For example，they have fewer chances to get in touch with others of their own age．Consequently，they sometimes lack the usual social skills．“No matter what，though，”states Lipscomb，“home-schooling is a growing trend．I think we'll be seeing more and more of this．”
【小题1】Compared with other students, Rowena and Billy are most different in the fact that ___________.
