The amount of carbon taken in by growing plants increased from 1982 through 1999 as
temperatures rose and the amount of carbon dioxide in the atmosphere increased. But a new study
in Friday ’ s edition of the journal Science found a drought - related decline in such plant growth
from 2000 to 2009，even though temperatures continued to climb.
As drought caused by warming reduces the land ’ s ability to take in carbon，the result could
be more carbon dioxide left in the atmosphere，and thus more warming，Zhao Maosheng from the
University of 
Montana explained in a telephone interview.
“This is a pretty serious warning that warmer temperatures are not going to endlessly improve
plant growth ’” co - author Steven Running，also from the University of Montana ’ said in a
statement. “ We see this as a bit of a surprise，and potentially significant on a policy level because
previous interpretations suggested global warming might actually help plant growth around the
world, “ he said.
Instead, he and Zhao found a small but measurable decline of about 1%，compared to a6%
increase in the past decade.
Their study，based on the data collected by NASA satellites，found that north areas continued
to increase plant growth，thanks to warmer temperatures and a longer growing season.
Someone commented, "This past decade’ s net decline in earthly productivity suggests that a
complex relationship between temperature, rainfall, cloudiness, and carbon dioxide, probably in
combination with other factors such as nutrients(营养）and land management，will determine
future patterns and trends in productivity.，，From the first paragraph, we can learnin

No one can change the weather. Nobody can control the weather. But if we read correctly the signs around us, we can tell what the more important changes in the weather will be. This way of telling what the weather will be like on the following day or two is called weather forecasting.
For many centuries and in all countries, people have studied the weather and tried to make weather forecasting. Rings around the sun are a sign of coming rain. That many people feel their joints(关节) hurt is a sign of wet weather. Some birds fly high if the weather is fine, but they fly near the ground if rainy or stormy weather is on the way. If you see a rainbow during rainy weather, this is a sign that the weather will become clear and fine. Such rainbows come in the evening. If the stars twinkle clearly at night, then fine weather will continue. If a fog appears in the morning just above a river, then the day will be warm. If the sunset is mostly red in colour, then the following day will be fine. If a rainbow appears in the morning, rainy weather will probably come.
Most of the above sayings have been made by the people who have used their eyes and brains to make weather forecasting.Which is true about weather forecasting?
| A．Weather forecasting is a way of telling what the weather will be like. |
| B．Weather forecasting is a report about the weather. |
| C．Weather forecasting is a sign of coming rain. |
| D．People can change the weather forecasting. |

Several years ago, a student working on a research project in my laboratory approached me with concern.“I’m doing something wrong,”she exclaimed. I had seen her research results and knew she was making good progress, so I was surprised to hear that she was having a problem. Over the next several days we went through her experiment; yet I could not find a problem. Finally, I asked her,“Why do you think you’re doing something wrong?” “Because I’m not getting what you said I should get,”she replied with some confusion.
Her response shocked me. I had not told her what she“should get”, but we had discussed some published hypotheses(假说) several weeks earlier. On seeing the research data that did not fit these predictions, I recognized that she had a new finding and came to change my hypotheses. But she was interpreting her results as a mistake. With almost four years of a college science major behind her, this student still had the common misunderstanding that science is a boring exercise in proving something we already know to be true.
But how can this happen? Throughout school, science is often described in textbooks as a series of“known”facts and figures; for example, DNA is a double helix; earthquakes occur at plate boundaries, etc. Unfortunately, the process by which these discoveries were made and how they fit into scientific progress are often ignored in the classroom. These details help show the nature of scientific discoveries and the tails help show the nature of scientific discoveries and the skepticism(质疑) that goes with new discoveries before they are accepted.
Understanding science is more than memorizing that DNA is a double helix. It is to have the ability to take in new information on diet, exercise, or disease and apply it to our own lives. Understanding the process of science and scientific problem-solving can help us make better decisions every day.The student thought her research project had gone wrong because.
| A．she was not making progress |
| B．her teacher told her so |
| C．she couldn’t get enough data |
| D．she had some unexpected findings |
How did the writer feel when he found out the reason for the student’s confusion?
| A．Confused. | B．Surprised. | C．Excited. | D．Pleased. |
What is to blame for the student’s misunderstanding about science?
| A．Her own carelessness. |
| B．Her teacher’s lack of experience. |
| C．The method of science education. |
| D．The publication of some wrong hypotheses. |
What is the last paragraph mainly about?
| A．The meaning of understanding science. |
| B．How to use known facts. |
| C．The best way to make scientific discoveries. |
| D．How to use scientific knowledge in daily life. |
Do you enjoy watching beautiful sunsets and seeing wildlife in some of the best parts of Wisconsin? Do you like being around people who share the same respect and love for natural resources? If you say“yes”, then a fisheries biologist is a great career choice for you.
As you can probably guess, education is very important. A Bachelor of Science degree in fisheries or biology is strongly recommended(推荐). Many biologists have a Master’s degree. But it’s not only good education that prepares you for a career as a fisheries biologist—field experience is also important. Volunteer work, internships(实习) and short-term fish technician positions are good ways to gain valuable training that can give you an edge in the competitive job market.
In addition to good education and field experience, a fisheries biologist needs other skills. You’ll spend a lot of time working with the public, so it’s important to feel comfortable talking to a variety of people. Good communication, listening, and presentation(陈述) skills are a must.
A common misconception among many people is that fisheries biologists get to fish all the time. Most biologists wish that were true. But as a fisheries biologist, you are especially busy during the fishing season, which leaves little time for you to actually go fishing. It’s sad, but true.
Each day brings something different in the life of a fisheries biologist. In the spring and fall, you spend a lot of time on the water shocking fish in order to sample the population, studying fish, and talking with people. The winter is spent analyzing(分析) fish data and communication with the public.
So if you find fish interesting and fun to learn about, and like working both outside and inside, consider a career as a fisheries biologist. You’ll never be bored!We can infer this passage was written to.
| A．advise us to respect and protect wildlife |
| B．encourage us to spend more time working outside |
| C．explain why education is important for our career |
| D．introduce a good career to those who are interested in wildlife |
What are Paragraphs 2 and 3 mainly about?
| A．Education needed to find a good job. |
| B．Requirements for becoming a fisheries biologist. |
| C．The benefits of being a fisheries biologist. |
| D．Some good ways to gain valuable training. |
The underlined word“misconception”in Paragraph 4 probably means“”。
| A．question | B．misunderstanding | C．dream | D．explanation |
It can be inferred from the passage that.
| A．fisheries biologists like working in winter most |
| B．fisheries biologists can easily get bored of their work |
| C．fisheries biologists get to fish all the time all year round |
| D．fisheries biologists spend a lot of time working outside in spring and fall |
England has been the birthplace of most of the great English-language theater written throughout history. Most of the plays in England that are truly famous have something in common. They usually come from a playwright(剧作家) with several famous plays.
Shakespeare
William Shakespeare is considered the most famous British playwright. Shakespeare has a large catalog(目录) of tragedies, comedies and history plays, and each category is home to some of the most famous plays ever written. Hamlet, Macbeth, Romeo and Juliet, Othello and Julius Caesar are all tragedies and performed in theaters around the world every year. Famous comedies include A Midsummer Night’s Dream and Much Ado About Nothing. In the history category, Richard Ⅲ and Henry Ⅴ are very famous.
Oscar Wilde and George Bernard Shaw
Several hundred years after Shakespeare, English people began to enjoy the works of Oscar Wilde and George Bernard Shaw. Wilde’s plays are still popular now, and The Importance of Being Earnest is both performed and studied extremely frequently. A Woman of No Importance and An Ideal Husband are among his other famous works. Shaw and Wilde were born within a few years of each other, but Shaw was a much more productive writer. His most famous plays include Pygmalion and Candida. Shaw’s plays are loved so much that an entire theater company is devoted to performing his work in Niagara-on-the-Lake in southern Ontario.
