一、阅读理解(共7小题，每小题2分，共14分）
A
Northern California’s national parks appear pure and clean, almost untouched. But scientists are finding that there is more to this wild area than one can see. Even in the deep forests and on the mountain tops, animals may be poisoned by pesticides used in valley farms far below.
Researchers with the United States Geological Survey (美国地质勘探局) are working late into the night. They are searching for and catching frogs in the mountains of the Sierra Nevada. The Pacific chorus frog (拟蝗蛙) breeds in the high mountains just as the snow melts. The pools basically fill with melt water, and as soon as the ponds melt the chorus frogs begin breeding there. Some Pacific chorus frogs in the mountains of California have tested positive for farming pesticides.
Gary Fellers is a researcher who once worked for the USGS. He and other team members are collecting the frogs to test them for agricultural poisons. No one farms in these forested national parks. However, winds carry chemicals from the Central Valley farming area into the mountains.
Kelly Smalling was the lead writer of the USGS study. “The decline of amphibians (两栖动物) has been documented for decades and decades. Some populations have gone extinct. And why these populations are declining is still a mystery.” Ms. Smalling says pesticides could be harming frogs and other amphibians.
The researchers tested pond water and soil from the bottom of the ponds. They were clean or almost free of pesticides. But tests on the bodies of the frogs showed the presence of 12 agricultural pesticides.
The concentration on the frog becomes greater than the concentration that is present on the water or some other part of the environment. Kelly Smalling says the next step is to find a way to deal with the pollution. “The first thing we need to do is understand how these chemicals that we’re finding harm the frogs. We have to understand the problem before we can fix it.”
1. Animals in Northern California’s national parks ________.

2. According to the text, the Pacific chorus frogs ________.
A. breed when it snows
B. are only found in the ocean
C. are studied by the scientists

Under the cold clear water of Lake Huron, researchers have found a fiveandahalffootlong piece of wood that is 8,900 years old. The wood, which is tapered (使成锥形) on one side in a way that looks deliberate, may provide important clues to a mysterious period in North American prehistory.
“This was the stage when humans gradually shifted from hunting large animals to fishing, gathering and agriculture，” said anthropologist John O’Shea. “But because most of the places in this area that prehistoric people lived in are now under water, we don’t have good evidence of this important shift itself. We just have clues from before and after the change.”
With support from the National Science Foundation (NSF) and the National Oceanic and Atmospheric Administration (NOAA), O’Shea and his colleague Guy Meadows began exploring the area several years ago. In 2009 they reported finding a series of stone features that they believe were “drive lanes” used by ancient Indian hunters.
Since that discovery, O’Shea and Meadows have worked on identifying human campsites, which are typically located away from hunting areas. On their 25foot boat, the researchers first spotted the ancient wood object using a small piece of equipment with a camera. Then a team of divers — including O’Shea — went down about 100 feet to get it.
The wood’s age has now been fixed by means of carbon dating. It is currently undergoing more detailed analyses to determine whether there has been human modification, which visual examination suggests. “The first thing you notice is that it appears to have been shaped with a rounded base and a pointed tip，” O’Shea said. “It must have been created. It looks like it might have been used as a tent pole or a pole to hang meat.”
In addition to the wood, the researchers have collected many other samples from the bottom of the lake. O’Shea and his colleagues will need to wait for calmer weather before they can resume their search for evidence of human life under the great lake.
4. During the mysterious period mentioned in the passage, the Lake Huron ________.
A. was deserted by ancient Indians
B. witnessed the start of agriculture
C. was taken up by large animals
D. began to be covered by water
5. Which of the following statements is WRONG?
A. The findings of John O’Shea and his colleagues may prove a previous theory.
B. The effort that John O’Shea and Meadows made before 2010 was meaningless.
C. Some equipment was used to support the discovery.
D. John O’Shea and his colleagues didn’t draw the final conclusion from visual examination.
6. What’s the fourth paragraph mainly about?
A. How the wood was found.
B. Why the wood is important.
C. Preparations that were made for the discovery of the wood.
D. Conclusions the experts have made from the discovery of the wood.
7. According to the passage, ________.
A. experts haven’t found out the age of the wood
B. experts first noticed the wood when they were diving
C. the wood was probably a humanmade tool
D. the wood is the most important discovery among all the samples found under the lake

Dear Mr. Headmaster,
I'm Li Hua, a student from Class One, Senior Two. I am writing to draw your attention to some improper behaviour among us students：littering and scribbling.
It makes our school dirty and unpleasant and does harm to the image of our school. I always feel ashamed whenever I see this. It is clearly not appropriate for a student to litter and scribble about. I wonder if the school could place more dustbins around and set up specific rules against such behaviour. At the same time, students should be encouraged to develop good habits and better behave themselves.
I believe that, with the joint efforts of both teachers and students, our school will become a more enjoyable place in the near future. Thank you for your consideration.
Yours faithfully,
Li Hua
