A green house is a building made of glass which is used for keeping warm when the outside temperature is low. In a similar way there are several gases in the atmosphere (mixture of gases that surround the earth) which trap the heat produced by the sun and prevent it from escaping. These gases are known as “greenhouse gases”. And the way in which they trap heat in the atmosphere is called the “greenhouse effect”. This is not simply air pollution. Most of the main greenhouse gases exist naturally in small amounts in our atmosphere, and without them the earth would be 30 degrees colder and human life would not exist. In other words, the greenhouse effect is a natural course which is to some degree helpful to us.
The problem is that in the last century and a half, we have been putting too many of these gases into the earth’s atmosphere by burning large quantities of coal and oil and by cutting down forest. The rapid increase in greenhouse gases is making the world warmer. The world’s temperature has already gone up by half a degree this century, and the sea level has risen by 10 centimetres. If the amount of carbon dioxide in the atmosphere doubles, there will probably be a rise in the earth’s temperature of between I and 4℃;. This may seem a small increase, but it would be enough to cause major changes in geography and agriculture. Large areas of the world would be flooded, and some areas would become dry and unable to produce crops. It is important, too, to consider that there may be a delay of about 30 years in the greenhouse effect. This means that we are probably experiencing only now the effect of the gases put into the atmosphere before the 1960s. Since then, our use of these gases has greatly increased. According to the passage, we can know “greenhouse effect” means_______.
| A．the way in which gases are used for keeping plants warm |
| B．a natural course that is to a certain degree useful to us |
| C．the way “greenhouse gases” trap heat on the earth |
| D．the whole course in which greenhouse gases prevent heat |
If there were no greenhouse effect,_______.
| A．all plants would not grow on our planet |
| B．soil would reduce the temperature by 30 degrees |
| C．man would breathe the cleaner air |
| D．people couldn’t live in the earth |
Which of the following is not true?
| A．Burning too much coal and oil produces lots of greenhouse gases. |
| B．It has become warm on the earth now than in the past. |
| C．Gases put into the atmosphere now will affect the earth years later. |
| D．The temperature in a greenhouse is as high as that in the atmosphere. |
Suppose the earth’s temperature rose by 3 degrees, _______.
| A．great harm will be done to mankind |
| B．the sea level would go up by 10 centimeters |
| C．all the land in the world would be flooded |
| D．crops would be unable to grow on the earth |
This passage mainly deals with ________.
| A．the concept (概念) and the harm of the greenhouse |
| B．the relation between greenhouse gases and man |
| C．the concept and change of greenhouse effect |
| D．the effect of the rise of the earth’s temperature |
Babies who watch TV are more likely to show late learning development and language at 14 months, especially if they are watching programs aimed at adults and older children, according to a new study, which would probably surprise those parents who leave their babies in front of a TV set.
Babies who watched 60 minutes of TV daily had developmental scores a third lower at 14 months than babies who were watching less TV. Although their developmental scores were still in the normal range, the difference may have been due to the fact that when children and parents are watching TV, they are missing the talking, playing and other communications that are important to learning and development.
This new study, which appeared in the Aechives of Pediatric and Adolescent Medicine, followed 259 lower-income families in New York, most of whom spoke Spanish as their primary language at home. Other studies of higher-income families have also come to the same conclusion: TV watching is not only non-educational, but it seems to slow down babies’ development.
But what about “good” TV, like Sesame Street? The researchers didn’t find any difference when compared to non-educational programs designed for small children, like Spongebob SquarePants. Earlier research by some of the same scientists, most of whom are at New York University School of Medicine’s Bellevue Hospital Centre, has found that parents whose children watch non-educational TV programs like Spongebob SquarePants spend less time reading to their children or teaching them.
At this point, parents reading this will probably be astonished. TV is so often a parent’s good friend, keeping children happily occupied（占时间）so that the adults can cook dinner, answer the phone, or take a shower. But, clearly, this electronic babysitter（保姆）is not an educational aid. It is best to make sure the babies are fast asleep if you have to watch TV.According to the first paragraph, 14-month-old babies who watch TV probably_______.
| A．learn things quickly |
| B．prefer programs for older children |
| C．surprise their parents with their development |
| D．speak later than babies who don’t |
Babies who watched 60 minutes of TV daily had lower developmental scores perhaps because _______.
| A．they watch non-educational programs |
| B．they have little communication with their parents |
| C．they lost interest in real things |
| D．their parents don’t speak English at home |
We can infer from the passage that______.
| A．Educational and non-educational TV have different effects on babies |
| B．Many parents leave babies to the TV to do their own things |
| C．Educational TV is very popular among higher-income families |
| D．Lower-income families tend to teach their babies at home |
Which would be the best title for the passage?
| A．Developing Better Learning Ability |
| B．A New Study on Babies’ Bad Habits |
| C．TV Watching Is Bad for Babies’ Brains |
| D．Make Sure Your Babies Watch “Good” TV Programs |
Who doesn’t have a clingy friend? You know, that person who often calls, texts, and e-mails. He often needs your attention, your feedback, or your help. Worse yet, he often gets antsy when you don’t reply immediately.
Is there ever a moment when you just want to turn off your phone and be alone? But you won’t do that to a friend. Actually there are better ways to deal with a clingy friend.
Give Yourself Some Time
If you really need some time for yourself, or you’re just tired of being the listener, just explain to your friend honestly that you want or need some time of your own. Even the most determined friends will understand and give you some space. Of course, those extremely clingy friends will still call, text, and e-mail. If that happens, just reply gently that you need some time for yourself.
Suggest an Activity for Your Friend
If you are tired of different get-togethers and outings, then you should advise your friend to do something alone. If you both like sports, you could tell your friend to have a try at the new gym. If your friend likes your suggestion, but insists that you go along, just explain that you’ve already visited the gym. Mention that you enjoy the gym. If you’re lucky , he’ll try it, and like it.
Introduce Your Clingy Friend to Others.
Your clingy friend may just be lonely or have trouble meeting new people. If that’s the case , introduce him to others with similar interests. He may just make some new friends.

Two traveling angels(天使) stopped to spend the night in the home of a wealthy family. The family was rude and refused to let the angels stay in the guest room. Instead the angels were given a space in the cold basement. As they made their bed on the hard floor, the older angel saw a hole in the wall and repaired it. When the younger angel asked why, the older angel replied: “Things aren’t always what they seem.”
The next night the pair came to rest at the house of a very poor but very hospitable(好客的)farmer and his wife. After sharing what little food they had, the couple let the angels sleep in their bed where they could have a good night’s rest. When the sun came up the next morning, the angels found the farmer and his wife in tears. Their only cow, whose milk had been their only income, lay dead in the field.
The younger angel was very angry and asked the older angel, “How could this happen? Why didn’t you watch out for the cow? The first man had everything, yet you watched over his house,” she accused. “The second family had little but was willing to share everything, and you did not help.”
“Things aren’t always what they seem,” the older angel replied. “When we stayed in the basement, I noticed there was gold stored in that hole in the wall. Since the owner was so greedy and unwilling to share his good fortune, I asked God if I could seal(封口)the wall so he couldn’t find it. Then last night as we slept in the farmer’s bed, the angel of death came for his wife. I asked God if the angel could take the cow instead. Things aren’t always what they seem.”Why did the older angel repair the hole for the rich family?
| A．Because the basement was too cold to stay in. |

Run Freely ——A Lesson about Courage
One afternoon, many years ago，I went to pick up my mother from work. I got there a little early so I the car by the roadside and waited for her.
As I looked the car window, there was a small park where I saw a little boy, around one and a half to two years old, freely on the grass as his mother watched from a short .The boy had a big smile on his face he had just been set free from a .The boy would then fall to the grass, get up, and without or looking back at his mother, run as fast as he could, again ,still with a on his face, as if nothing had happened.
Kids, when they fall down, they don’t consider their falling down as a failure, but , they treat it as a learning experience. They feel inspired to try and try again until they .
Not only was I impressed by the boy’s courage, but I was touched by the manner in which he ran. With each attempt, he looked so , so natural, without signs of fear, nervousness, or of being disappointed. His only was to run freely and to do it as effectively as he could. He was just being a , just being himself. He was not looking for or worrying about whether was watching. He wasn’t concerned about being judged. He didn’t seem to be bothered(困扰) by the fact that maybe someone would see him and that it would be if he did fall. No, all that to him was to complete the task of activity at hand to the best of his ability, feeling the experience of running fully and freely.
I learned a lot from that observation and , and have successfully brought that lesson with me in life.

As many as 4 out of every 1,000 infants born today have permanent hearing loss. When parents learn that their child has hearing loss, they are faced with many difficult decisions. These decisions can include choosing therapies and schools, as well as finding financial help for hearing aids or cochlear implants (人工耳蜗).
Help Me Hear Foundation is a public charity that gives the gift of hearing to deaf children from families existing on very low incomes around the world.
Help Me Hear Foundation believes that a child’s first years of development are critical. Being able to hear is vital to human, and Help Me Hear Foundation seeks to provide a positive lasting impression on society through its programs.
Recipients(受助人) of Help Me Hear Foundation’s benefits receive state-of-the-art hearing devices that otherwise would cost thousands of dollars per child over the course of their lifetime. The Foundation raises money through donations for hearing aids and cochlear implants, which saves recipients and their families on average over $50,000 on related expenses.
The Foundation tries to be a transparent charity, and wants to be a catalyst for allowing deaf and hearing-impaired children to develop in a typical fashion alongside their peers.
Needy families can obtain information on specific services, and find out about deafness education by visiting the Help Me Hear Foundation’s website. The website offers helpful information on how hearing aids work, and how hearing aids ease many of the learning and language challenges that hearing-impaired children deal with on a daily basis.Help Me Hear Foundation was probably set up to _____.
