In the 1920s demand for American farm products fell, as European countries began to recover from World War I and started austerity (紧缩) programs to reduce their imports. The result was a sharp drop in farm prices. This period was more disastrous for farmers than earlier times had been, because farmers were no longer self-sufficient. They were paying for machinery, seed, and fertilizer, and they were also buying consumer goods. The prices of the items farmers bought remained constant, while prices they received for their products fell. These developments were made worse by the Great Depression, which began in 1929 and extended throughout the 1939s.
In 1929, under President Herbert Hoover, the Federal Farm Board was organized. It established the principle of direct interference (干预) with supply and demand, and it represented the first national commitment to provide greater economic stability for farmers.
President Hoover's successor attached even more importance to this problem. One of the first measures proposed by President Franklin D. Roosevelt when he took office in 1933 was the Agricultural Adjustment Act, which was later passed by Congress. This law gave the Secretary of Agriculture the power to reduce production through voluntary agreements with farmers who were paid to take their land out of use. A deliberate shortage of farm products was planned in an effort to raise prices. This law was declared unconstitutional (违背宪法的) by the Supreme Court on the grounds that general taxes were being collected to pay one special group of people. However, new laws were passed immediately that achieved the same result of resting soil and providing flood-control measures, but which were based on the principle of soil conservation. The Roosevelt Administration believed that rebuilding the nation’s soil was in the national interest and was not simply a plan to help farmers at the expense of other citizens. Later the government guaranteed loans to farmers so that they could buy farm machinery, hybrid (杂交) grain, and fertilizers.
53.What caused the problem in the demand for American farm products?
A. The effect of the Great Depression.
B. The shrinking of overseas markets.
C. The destruction caused by the First World War.
D. The increased exports of European countries.
54. The word “successor” refers to ______.
A. President Hoover B. US Secretary of State
C. President Franklin D. Roosevelt D. US Secretary of Agriculture
55. The Agricultural Adjustment Act encouraged American farmers to ______.
A. reduce their scale of production
B. make full use of their land
C. adjust the prices of their farm products
D. be self-sufficient in agricultural production
56.The Supreme Court rejected the Agricultural Adjustment Act because it believed that the Act ______.
A. might cause greater shortage of farm products
B. didn't give the Secretary of Agriculture enough power
C. would benefit neither the government nor the farmers
D. benefited one group of citizens at the expense of others

Teamwork is just as important in science as it is on the playing field or in the gym. Scientific investigations (调查) are almost always carried out by teams of people working together. Ideas are shared, experiences are designed, data are analyzed, and results are evaluated and shared with other investigators. Group work is necessary, and is usually more productive than working alone.
Several times throughout the year you may be asked to work with one or more of your classmates. Whatever teh task your group is assigned, a few rules need to be followed to ensure a productive and successful experience.
What comes first is to keep an open mind, becasue everyone’s ideas deserve consideration and each group member can make his or her own contribution. Secondly, it makes a job easier to divide the group task among all group members. Choose a role on the team that is best suited to your particular strengths. Thirdly, always work together, take turns, and encourage each other by listening, clarifying, and trusting one another. Mutual support and trust often make a great difference.
Activities like investigations are most effective when done by small groups. Here are some more suggestions for effective team performance during these activities: Make sure each group member understands and agrees to the task given to him or her, and everyone knows exactly when, why and what to do; take turns doing various tasks during similar and repeated activities; be aware of where other group members are and what they are doing so as to ensure safety; be responsible for your own learning, though it is by no means unwise to compare your observations with those of other group members.
When there is research to be done, divide the topic into several areas, and this can explore the issue in a very detailed way. You are encouraged to keep records of the sources used each person, which helps you trace back to the origin of the problems that may happen unexpectedly. A format for exchanging information (e.g. photocopies of notes, oral discussion, etc.) is also important, for a well-chosen method not only strengthens what you present but also makes yourself easily understood. When the time comes to make a decision and take a position on an issue, allow for the contributions of each member of the group. Most important of all, it is always wise to make decisions by compromise and agreement.
After you’ve completed a task with your team, make an evaluation of the team’s effectiveness — the strengths and weaknesses, opportunities and challenges.

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 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.
59. 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
60. Only a small part of the Sun’s energy reaches the Earth’s surface because most of it _______________.
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
61. 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
What time is it? Most people are pretty accurate in their answer. And if you don’t know for sure, it’s a very likely that you can find out. There may be a watch on your wrist, there may be a clock on the wall, desk, or computer screen; or maybe you’re riding in a car that has a clock in the dashboard (仪表板).
Even if you don’t have a timepiece of some sort nearby, your body keeps its own beat. Humans have an internal clock that regulates (调节) the beating of our heart, the pace of our breathing, the discharge (排出) of chemicals within our bloodstream, and many other bodily functions.
Time is something from which we can’t escape. Even if we ignore it, it’s still going by, ticking away, second by second, minute by minute, hour by hour. So the main issue in using your time well is, “Who’s in charge?” We can allow time to slip by and let it be our enemy. Or we can take control of it and make it our ally.
By taking control of how you spend your time, you’ll increase your chances of becoming a more successful student. Perhaps more importantly, the better you are at managing the time you devote to your studies, the more time you’ll have to spend on your outside interests.
The aim of time management is not to schedule every moment so we become slaves of a timetable that governs every waking moment of the day. Instead, the aim is to make informed choices as to how we use our time. Rather than letting the day go by, largely without our awareness, what we are going to discuss next can make us better able to control time for our own purposes.The underlined word “ally” in Para. 3 more likely means somebody or something that is _________.
| A．your slave and serves you |
| B．your supporter and helps you |
| C．under your control and obeys you |
| D．under your influence and follows you |
The author intends to tell us that time _____________.
| A．could be regulated by a timepiece such as a clock or a watch |
| B．could be managed by the internal clock of human bodies |
| C．should be well managed for our own interest |
| D．should be saved for outside interests |
In the next part, the author would most probably discuss with you ________.
| A．how to keep up with the times | B．how to make up for lost time |
| C．how to have a good time | D．how to make good use of time |
Melissa Poe was 9 years old when she began a campaign for a cleaner environment by writing a letter to the then President Bush. Through her on efforts, her letter was reproduced on over 250 donated billboards (广告牌)across the country.
The response to her request for help was so huge that Poe established Kids For A Cleaner Environment (Kids F.A.C.E.) in 1989. There are now 300,000 members of Kids F.A.C.E. worldwide and it is the world’s largest youth environmental organization.
Poe has also asked the National Park Service to carry out a “Children’s Forest” project in every national park. In 1992, she was invited one of only six children in the world to speak at the Earth Summit in Brazil as part of the Voices of the future Program. In 1993, she was given a Caring Award for her efforts by the Caring Institute.
Since the organization started, Kids F.A.C.E. members have distributed and planted over 1 million trees! Ongoing tree-planting projects include Kids’ Yards — the creation of backyard wildlife habitats (栖息地) and now Kids F.A.C.E. is involved in the exciting Odyssey, which is a great way to start helping.
“We try to tell kids that it’s not OK to be lazy,” she explains, “You need to start being a response, environmentally friendly person now, right now, before you become a resource-sucking adult.”
