The Sun is the major source of energy for our planet. It causes the evaporation (蒸发) of water from the
oceans and lakes. Sunlight also provides the energy used by green plants to make their own food. These
green plants then provide food for all organisms (生物) on the Earth.
Much of the energy that comes from the Sun never reaches the Earth"s surface. It is either reflected
or absorbed by the gases in the upper atmosphere. Of the energy that reaches the lower atmosphere, 30%
is reflected by clouds or the Earth"s surface. The remaining 70% warms the surface of the planet, causes
water to evaporate, and provides energy for the water cycle and weather. Only a tiny part, approximately
0.023%, is actually used by green plants to produce food.
Many gases found in the atmosphere actually reflect heat energy escaping from the Earth"s surface back
to the Earth. These gases act like the glass of a greenhouse in that they allow energy from the Sun to enter
but prevent energy from leaving. They are therefore called greenhouse gases.
When sunlight strikes an object, some of the energy is absorbed and some is reflected. The amount
reflected depends on the surface. For example, you"ve probably noticed how bright snow is when sunlight
falls on it. Snow reflects most of the energy from the Sun, so it contributes to the low temperatures of winter.
Dark-coloured surfaces, such as dark soil or forest, absorb more energy and help warm the surrounding air.
B. water from oceans and lakes
C. energy from the Sun
D. greenhouse gases in the sky
B. reflected by the gases in the upper atmosphere
C. lost in the upper and lower atmosphere
D. used to evaporate water from the oceans and lakes
B. a forest looks dark in winter because it absorbs solar energy
C. only 0.023% of the energy from the Sun is made use of on the Earth
D. greenhouse gases allow heat energy to escape from the Earth"s surface

have been increasingly developed and marketed in many countries in the word, mainly on the basis of their
promise to end the worldwide food crisis. But can GM technology solve world hunger problems? Even if it
would, is it the best solution?
Despite what it promises, GM technology actually has not increased the production potential of any corp.
In fact, studies show that the most crown GM crop.
GM soybeans, has suffered reduced productivity. For instance, a report than analyzed nearly two decades
of research on major GM food crops shows that GM engineering has failed to significantly increase US crop
production.
Something else, however, has been on the rise, While GM seeds are expensive, GM companies tell farmers
that they will make good profits by saving money on pesticides (***虫剂). On the contrary, US government
data show that GM crops in the US have produced an overall increase in pesticide use compared to traditional
crops. "The promise was that you could use less chemicals and boost production. But neither is true," said Bill
Christenson, President of the US National Farm Coalition.
At the same time, the authors of the book World Hunger: Twelve Myths argue that there actually is more
than enough food in the world and that the hunger crisis is not caused by production, but by problems in food
distribution and politics. These indeed deserve our efforts and money. Meanwhile, the rise in food prices results
from the increased use of crops for fuel rather than food, according to a 2008 World Bank report.
As a matter of fact, scientists see better ways to feed the world. Another World Bank report concluded that
GM crops have little to offer to the challenges of worldwide poverty and hunger, because better ways out are
available, among which "green" farming is supposed to be the first choice.
B. by comparison
C. by example
D. by process
B. Evaluate.
C. Obtain.
D. Increase.
B. use of less chemicals
C. fair distribution of their crops
D. using more crops for fuel
B. Defensive
C. Disapproving
D. Casual
A. A sense of humour is not an inborn ability. B. A sense of humour can be developed in our life. C. A sense of humour helps us from several aspects. D. A sense of humour means more than telling jokes. E. A sense of humour can be expressed in many ways. F. A sense of humour helps people to better enjoy life. |

| An idea that started in Seattle"s public library has spread throughout America and beyond. The concept is simple: help to build a sense of community in a city by getting everyone to read the same book at the same tome. In addition to encouraging reading as a pursuit (追求) to be enjoyed by all, the program allows strangers to communicate by discussing the book on the bus, as well as promoting reading as an experience to be shared in families and schools. The idea came from Seattle librarian Nancy Pearl who launched (发起) the "If All of Seattle Read the Same Book" project in 1998. Her original program used author visits, study guides and book discussion groups to bring people together with a book, but the idea has since expanded to many other American cities, and even to Hong Kong. In Chicago, the mayor (市长) appeared on television to announce the choice of To Kill a Mockingbird as the first book in the "One Book, One Chicago" program. As a result, reading clubs and neighborhood groups sprang up around the city. Across the US, stories emerged of parents and children reading to each other at night and strangers chatting away on the bus about plot and character. The only problem arose in New York, where local readers could not decide on one book to represent the huge and diverse population. This may show that the idea works best in medium-sized cities or large towns, where a greater sense of unity (一致) can be achieved.Or it may show that New Yorkers rather missed the point, putting all their energy. And passion into the choice of the book rather than discussion about a book itself. Ultimately was Nancy points out, the level of success is not measured by how many people read a book, but by how many people are enriched by the process or have enjoyed speaking to someone with whom they would not otherwise have shared a word. |

| A. To invite authors to guide readers. B. To encourage people to read and share. C. To involve people in community service. D. To promote the friendship between cities. |
| 2. Why was it difficult for New Yorkers to carry out the project? |
| A. They had little interest in reading. B. They were too busy to read a book. C. They came from many different backgrounds. D. They lacked support from the locate government. |
| 3. According to the passage, where would the project be more easily carried out? |
| A. In large communities with little sense of unity B. In large cities where libraries are far from home C. In medium-sized cities with a diverse population D. In large towns where agreement can be quickly reached |
| 4. The underlined words "shared a word" in Paragraph 5 probably mean _____. |
| A. exchanged ideas with each other B. discussed the meaning of a word C. gamed life experience D. used the same language |
| 5. According to Nancy, the degree of students of the project is judged by _____. |
| A. the careful selection of a proper book B. the growing popularity of the writers C. the number of people who benefit from reading. D. the number of books that each person reads. |

| In college, Spring Break (春假) is usually associated with the beach, parties and sleepless nights, bringing about relaxation, free time and friends. Students who wish to spend their break doing something productive and rewarding, however, may choose to participate in the Alternative Break Program. It places college students in communities both at home and abroad. The Program allows students to take part in various projects dealing with issues such as literacy (识字), homelessness and the environment. It includes helping kids with their lessons, raising money for families in need and collecting data for environmental research. The hope is that, by getting themselves involved in different environments, students will have the opportunity to learn about members of communities and broaden their view. In turn, they will incorporate (融 合) their experiences and lessons learned into their own communities. In a word, the Program aims to encourage students to be active citizens and engage themselves in making a difference in society. In the spring of 2006, about 36,000 students in the USA participated in the Alternative Break Program. Samantha Giacobozzi, now director of the Program, has been on five alternative break trips herself, including trips to New Orleans, India and Dominican Republic. "I was a student who went on alternative break trips and had my life totally transformed by that experience," she said. "Every year, we meet many students who have attended the Program. You can see changes in their life that are connected with their alternative break experiences." The Program began in 1991. Today, it has become increasingly popular with college students in the United States. |
