The effects of air pollution on natural conditions have been a disturbing problem for many years. Some scientists hold the view that the air inside houses may be more dangerous than the air outside. It may even be one hundred times worse.
Most scientists agree that every modern house has some kind of indoor pollution, which can cause a person to feel tired, to suffer eye pain, headache and other problems. Believe it or not, some pollutants can cause breathing diseases of blood and even cancer.
What made us feel relieved is that there’s growing concern about the problem now. It is true that when builders began constructing houses and offices they did not want to waste energy. To do this they built buildings that prevented or limited the flow of air between inside and outside. For the same purpose, man-made building materials were employed to build houses, which are now known to let out some harmful gases.
Facing the serious challenge, scientists have been searching for a way to handle the problem. To everyone’s delight, they discovered a natural pollution control system for building—green plants, though they do not really know how plants control air pollution. Scientists suppose that a plant’s leaves absorb or take in the pollutants and in exchange gives out oxygen through its leaves and tiny organizations on its roots. Therefore they recommend that all buildings should have one large plant or several small plants inside for every nine square meters of space. Because studies indicate that different plants absorb different chemicals, the most effective way to clean the air is to use different kinds of plants. In conclusion, having green plants inside your house can make it a prettier and healthier place. Why not try?Which of the following statements is TRUR?

Chinese and Nigerian media should pay more attention to their own growing roles and strive to present a reliable image of China to African audiences and vice versa(反之亦然). Agreement on this important step in ongoing cooperation between the two sides was reached by media representatives attending a media forum on September 19 in Abuja, Nigeria.
The agreement comes in the wake of increasing attention being paid by the international community on Africa's deepening relationship with China. "This presents an important opportunity for media in China, Nigeria and other African countries. We should seize the moment to expand cooperation between Chinese and Nigeria media, increase our say, and contribute to cooperation between China, Nigeria and Africa as a whole," said Li Wufeng, Vice Minister of the State Council Information Office at the China-Nigeria Media meeting.
The media meeting was jointly held by the State Council Information Office, the Chinese Embassy in Nigeria, and the Federal Ministry of Education, Nigeria. It formed part of the "Experience China" program, which aims to increase cultural exchanges and mutual understanding between China and other parts of the world.
In the past, due to poor communication facilities, China and African countries could only learn about each other through third parties, in particular Western media, which may have given rise to and perpetuated misunderstandings.
"China is still not a constant feature or subject on the front page and prime time in the news media in Nigeria unless there are disasters and alleged human rights abuses to be reported," said Martins Oloja, Editor of The Guardian.
Major Western media continue to promote a Cold War mentality and view Sino-African ties through the lens of geopolitics, framing everything as competition between East and West, Chinese and Nigerian media professionals said at the forum. Some Western media outlets accuse China of ignoring mutually beneficial solutions or sustainable development of African people, while robbing the continent of its natural resources.
"Nigerians cannot expect Aljazeera or BBC to report on Africa, and indeed Nigeria and China relations, the way we want," said Oloja.

It’s common for parents to feel emotional when the moment comes for their child to leave home and go to university. Even parents who don’t speak about the event are likely to feel a sense of sadness because it’s the end of an era where you and your family were at the centre of your child’s world. As a parent you’ll probably continue to support your child in different ways, but the main job of raising your child is over. It’s a huge change for everyone involved.
There are a few things that you can do to make the transition easier. Plan carefully for your child’s departure and think about how you can help. Many parents take their child to university for the first time. If you decide to do that, be ready to feel a real wrench when the time comes to say goodbye. Your child will probably be as nervous as you are about the moment when you finally say goodbye – but that might not show!
Be positive and cheerful about the choice your child has made to continue studying, and plan to leave once you’ve unpacked the car and looked around your child’s new living accommodations. If you can, save your tears for the car – you’ll make things easier on your child and yourself.
The more you’ve invested in being a parent, the more you’ll feel a sense of loss, so the sadness you feel now is a sign that you’ve been a good mom or dad. Remind yourself that parenting is all about raising an independent and confident child who functions well without you. If your child quickly settles and starts enjoying himself, you should congratulate yourself.
It’s also only fair to allow yourself some time to grieve. Don’t expect to pick yourself up and move on straight away. But you may decide to find a hobby or sport to fill your extra time. Perhaps you’ve always wanted to learn a new language, go to yoga classes or take up swimming. You may decide to spend more time with family and close friends, who are likely to be feeling the absence of your child as well.
Agree on the best approach to staying in touch before your child leaves, and stick to your agreement. Try not to panic if your child doesn’t respond immediately – remember, they’re starting a new and busy life.The underlined word “wrench” in Paragraph 2 means a feeling of ________.
| A．sorrow | B．regret | C．anger | D．love |

Keeping a busy social life among lots of friends may keep people thinner than spending hours doing some exercises, according to scientists. They say that socializing and meeting with friends help increase levels of brown fat in the body which burns calories to produce heat.
Living in an exciting social environment was found to reduce fat in mice's belly by half over four weeks, even if they ate more. US researchers say that social excitement aids weight loss by turning white fat into brown. White fat stores calories and makes us fatter, while brown burns energy to produce heat. Turning white fat into brown is extremely difficult, normally requiring long-term stay in cold conditions or exciting part of the body's nervous system.
However, scientists from Ohio State University now think that having a busy social life is an even more effective way of changing white fat into brown. The team came up with their theory by studying the effects of various living environments on mice. Those, who lived alongside a greater number of mice, had more space and toys to excite themselves and then lost far more weight over the course of the study than their “couch potato" fellows.
Study author, Dr Matthew During, whose team’s findings appear in the journal Cell Metabolism, said, “I'm still amazed at the degree of fat loss that occurs.” explaining how new technology had threatened face-to-face socializing, he added, “It's not just a sedentary(久坐的) lifestyle and high calorie foods, but an increasing lack of social activities.” Co-author Dr Lei Cao said，“Loneliness is a potential factor for cancer and death; it's equal to cigarette smoking to a certain extent. Social activities are very vital.”What information can we get from the first two paragraphs?

As a senior, my future is always on my mind. To be exact, thoughts of the future have kept me up countless nights and made me worry enough to do poorly on more than one test. Because of this, words of wisdom are a source of comfort. Steve Jobs gave a speech to Stanford’s graduating class in 2005 and his words resound repeatedly in my mind whenever I think about my future.
It wasn’t always like that, though. It started when I became a junior, when college came into view. It’s the first big step to making your life your own. So when Jobs discussed his life as a student, some fears were eased. He, too, felt the need to attend college to make something of himself. He faced what many are extremely afraid of: uncertainty. His lack of understanding caused him to stop attending college and focus on what he felt was important. His story had a happy ending, of course, since he certainly turned out well.
This doesn’t mean that students shouldn’t attend college, but rather that they shouldn’t worry so much. You’ll get where you need to go, even if your path is a bit more winding than you’d like.
Jobs talked about the hardships in his work. His love of his work helped him carry on and he got where he was meant to be, which restates the point: don’t panic.
One particular part of his speech stayed with me. Steve Jobs quoted the saying “Stay hungry, stay foolish” and it has become my motto. Staying foolish is realizing that you are still a fool, no matter how much you’ve learned or experienced. There is always more to explore. Staying hungry is wanting to find those things about which you are still uneducated.
Steve Jobs’s level of success is attainable, and I aim to prove that. With the will power to go into the world living every day like it’s my last and allowing the future to take care of itself, I will do great things. In the last moments of my life, I’ll be proud of what I have done and hope to have all the wisdom a person could wish for.The author felt worried when _________.
| A．he had to take tests at school | B．he thought about his future |
| C．he had lots of sleepless nights | D．he searched for words of wisdom |
What did the author gain from Jobs’s speech?
| A．Courage to drop out of school. | B．Confidence in defeating Jobs. |
| C．Interest in computer industry. | D．Bravery to face uncertainties. |
What did NOT Steve Jobs encourage students to do in his speech?
| A．Have the desire to learn more. | B．Be content with what they know. |
| C．Stay calm in the face of hardships. | D．Be modest so as to learn more. |
An older friend once gave me a piece of advice, “Enjoy the last few weeks of college,” she said, “since college is the best time of your life.”
This was not the first time I’d heard such a statement, but with graduation fast coming close, her words especially struck me. It seemed a bit disappointing to reach one's life peak at only 22 years of age, but in her opinion, college had been one of the best times in my life so far. I made friends, took classes, and learned a great deal about myself. But I was also excited for the time after college—moving to a new city, starting a new job, and becoming a "real" person. I hoped that my great dreams were practical.
Then, last week I read a column in Real Simple Magazine called 100 Years of Attitude, in which women 100 years or older shared their life experiences and views. I noticed that none of them considered college as the "best" time of their life. Not all of them went to college, but still in most cases their teens and twenties were not the best times of their life. They said some of their favorite times were raising their children, traveling after retirement, and even enjoying their present time and age.
Enjoying one's present time and age was a clear theme of the interviews. A piece of advice given by the women was about the importance of making the best of all situations. I think it more accurate than that of my friend; I can say with certainty that if I am lucky enough to make it to 100, I refuse to spend the last 80 years of my life plummeting (跌落) downhill, or even leveling off.
I am sure that our eagerness and devotion will make us college students live a meaningful life. We will not just look backwards or miss our college days. We will look forward in excitement about continued journey uphill. Which of the following opinions does the writer agree with?
| A．College is the best time of one’s life. |
| B．Twenties were the best time of the old people. |
| C．One should make the best of all situations. |
| D．One should not look backwards at their college time. |
In the second paragraph, the writer wants to say ______.
| A．her achievements in college would be the peak of her success |
| B．she is looking forward to living as a “real” person in college |
| C．she becomes more and more uneasy with graduation |
| D．she is satisfied with the college life but is hopeful for the future |
The column the writer read is mainly about those old women’s ______.
| A．best time of life at youth | B．life experiences and views |
| C．different opinions about life | D．favorite time with best friends |
By saying “I refuse to spend the last 80 years of my life plummeting downhill, or even leveling off” (in Paragraph 4), the writer really means ______.
| A．she will not spend the rest of her time at college |
| B．she will not just obtain a college level certificate |
| C．she will not be satisfied with what she has already accomplished |
| D．she will not be content with the life in the future |
