We experience different forms of the Sun"s energy every day. We can see its light and feel its warmth.
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. |
| 1. According to the passage, the root cause for weather changes on the Earth is _____. |
A. the atmosphere surrounding the Earth
B. water from oceans and lakes
C. energy from the Sun
D. greenhouse gases in the sky |
| 2. Only a small part of the Sun"s energy reaches the Earth"s surface because most of it is _____. |
A. absorbed by the clouds in the lower atmosphere
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 |
| 3. We learn from the passage that _____. |
A. all living things on the Earth depend on the Sun for their food
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 |

Ever since they were first put on the market in the early 1990s, genetically modified (GM, 转基因) foods
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. |
| 1. The author develops the second paragraph mainly _____. |
A. by classification
B. by comparison
C. by example
D. by process |
| 2. What does the underlined word "boost" in the third paragraph probably mean? |
A. Control.
B. Evaluate.
C. Obtain.
D. Increase. |
| 3. GM companies promise farmers that they will benefit from ______. |
A. practicing "green" farming
B. use of less chemicals
C. fair distribution of their crops
D. using more crops for fuel |
| 4. Which of the following best describes the attitude of the author towards GM technology? |
A. Optimistic
B. Defensive
C. Disapproving
D. Casual |

Set to open in 2013, the ￡188m LoB is already beginning to take shape next to the Birmingham Repertory
Theatre, with which it will share some equipment.
As digital media (媒介) is important to its idea. The project is already providing chances for some of the

designed by Baden, the Birmingham virtual worlds specialists. Not only have the public been able to learn about
LoB, but the virtual one has also enabled those working on the LoB to understand the building and how it will
work before it even opens.
Two other small Birmingham-based digital companies are working on the LoB projects. Substrat, a digital
design company, is developing what it calls an example of an "enlarged reality" project. It is about the use of
an exciting smart phone, an important part of which are the early stages of development is an online library of
figures of the city being built up by a content company in Cahoots, in which users with the encouraged to add

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. | | 1. What is the purpose of the project launched by Nancy? | 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.
