第二部分 阅读理解（共两节，满分 40分）
第一节（共15小题；每小题2分，满分30分）

Imagine a classroom missing the one thing that’s long been considered a necessary part to reading and writing ------ paper. No notebooks, no textbooks, no test paper. Nor are there any pencils or pens, which always seem to run out of ink at the critical moment.
A “paperless classroom” is what more and more schools are trying to achieve.
Students don’t do any handwriting in this class. Instead, they use palm size, or specially-designed computers. The teacher downloads texts from Internet libraries and sends them to every student’s personal computer.
Having computers also means that students can use the Web. They can look up information on any subject they’re studying from math to social science.
High school teacher Judy Harrel in Florida, US, described how her class used the Web to learn about the war in Afghanistan (阿富汗) before.
“We could touch every side of the country through different sites from the forest to refugee camps (难民营)”, she said. “Using a book that’s three or four years old is impossible.”
And exams can go online too. At a high school in Tennessee, US, students take tests on their own computers. The teacher records the grades on the network for everyone to see and then copies them to his own electronic grade book.
A paperless classroom is a big step towards reducing the waste of paper. High school teacher Stephanie Sorrell in Kentucky, US, said she used to give about 900 pieces of paper each week to each student.
“Think about the money and trees we could save with the computer,” she said.
But, with all this technology, there’s always the risk that the machines will break down. So, in case of a power failure or technical problems, paper textbooks are still widely available for these hi-tech students.
46. What does “run out of ink at the critical moment” in the first paragraph mean?
A. Pens may not write well at the critical moment.
B. Pens get lost easily, so you may not find them at the critical moment.
C. Pens may have little or no ink at the critical moment.
D. Pens use ink, while pencils don’t.
47. The high school teacher, Judy Harrell, used the example of her class to show that ______.
A. the Web could take them everywhere
B. the Web taught them a lot
C. the Web is a good tool for information
D. the Web, better than the textbooks, can give the latest and comprehensive (全面的) information
48. The paperless classrooms will benefit ______ most.
A. students            B. teachers             C. trees     D. computers 


(D)
Malaria, the world's most widespread parasitic（寄生虫引起的）disease, kills as many as three million people every year—almost all of whom are under five, very poor, and African. In most years, more than five hundred million cases of illness result from the disease, although exact numbers are difficult to assess because many people don't （or can't） seek care. It is not unusual for a family earning less than two hundred dollars a year to spend a quarter of its income on malaria treatment, and what they often get no longer works. In countries like Tanzania, Mozambique, and the Gambia, no family, village, hospital, or workplace can remain unaffected for long.
Malaria starts suddenly, with violent chills, which are soon followed by an intense fever and, often, headaches. As the parasites multiply, they take over the entire body. Malaria parasites live by eating the red blood cells they infect （感染）. They can also attach themselves to blood vessels in the brain. If it doesn't kill you, malaria can happen again and again for years. The disease passed on to humans by female mosquitoes infected with one of four species of parasite. Together, the mosquito and the parasite are the most deadly couple in the history of the earth—and one of the most successful. Malaria has five thousand genes, and its ability to change rapidly to defend itself and resist new drugs has made it nearly impossible to control. Studies show that mosquitoes are passing on the virus more frequently, and there are more outbreaks in cities with large populations. Some of the disease's spread is due to global warming.
For decades, the first-choice treatment for malaria parasites in Africa has been chloroquine, a chemical which is very cheap and easy to make. Unfortunately, in most parts of the world, malaria parasites have become resistant to it. Successful alternatives that help prevent resistance are already available, but they have been in short supply and are very expensive. If these drugs should fail, nobody knows what would come next.
76. According to paragraph 1, many people don't seek care because _______.
A. they are too poor
B. it is unusual to seek care
C. they can remain unaffected for long
D. there are too many people suffering from the disease
77. People suffering from malaria _______.
A. have to kill female mosquitoes      B. have ability to defend parasites
C. have their red blood cells infected    D. have sudden fever, followed by chills
78. Which of the following may be the reason for the wide spread of the disease?
A. Its resistance to global warming.
B. Its ability to pass on the virus frequently.
C. Its outbreaks in cities with large populations.
D. Its ability to defend itself and resist new drugs.
79. It can be inferred from the passage that _______.            .
A. no drugs have been found to treat the disease
B. the alternative treatment is not easily available to most people
C. malaria has developed its ability to resist parasites
D. nobody knows what will be the drug to treat the disease
80. Which of the following questions has NOT been discussed in the passage?
A. How can we know one is suffering from malaria?
B. How many people are killed by malaria each year?
C. Why are there so many people suffering from malaria?
D. What has been done to keep people unaffected for long?


B
Wolves are in the news these days, especially with the controversial（有争议的）Alaskan Wolf Hunting Festival being a focus of public attention. Since these animals are getting more attention in the outer world, they may be more likely to show up in your inner world and may take on many forms and have many meanings.
Wolves live in a pack（狼群）and they have a leader, a guide who is responsible for directing the pack and keeping it safe. If a wolf appears in your dream and you have a positive relationship with the wolf, it may suggest your own leadership abilities. Wolves in dreams may also mean the need for trusting your own internal leader-the soft howl from the bottom of your own heart.
While wolves certainly do howl, it is till unknown why they howl at the moon. The wolf’s how is actually a form of communication. Wolves may howl as a form of making friends, or as a warning, or to indicate that they are last and need help. Is your dream wolf howling? If so, what emotions exist in the dream? Do you feel lost and in need of guidance, do you feel like you’ve lost your “pack”? Do you feel the need to let others know they are crossing your land? Or are you simply filled whit a sense of joy that can only be expressed in a howl?
Wolves can be experienced hunters, and often appear in folk stories as something harmless when in fact it is there to do great harm. Are there any wolves in sheep’s clothing in your life? Often we have intuition（直觉）about people or situations, feelings that these people or situations should be avoided, but we ignore them based on their harmless outer appearance. Wolves in dreams could be signs that there are hidden dangers in your life. Never ignore your intuition because it doesn’t make any sense. Your intuition exists to guide and protect you and it can discover a wolf  long before it removes its woolen suit.

A．to support the main idea of the text       B．to introduce the topic of the passage
C．to show his pity for the wolves       D．to prove wolves are getting more attention
