Ⅱ.阅读理解(建议用时15′)
A
Since the beginning of the year, smog (雾霾) has covered parts of North China. In January, Beijing saw only five days without smog. The rising PM2.5 readings terrified many people, and some health experts said that whenever the smog gets serious, hospitals receive more patients suffering acute respiratory (呼吸系统) and heart diseases.
Later, news of polluted underground water in some provinces scared people who wondered whether the water they drink is safe.
So the need to emphasize environmental protection while developing the economy is heard everywhere.
Smog is especially a common concern. As a popular online post said, air may be the only thing that is equal for everyone, despite your income or profession. People with higher incomes are able to drink only bottled spring water and eat only organic food by paying higher prices, but they breathe the same air as everyone else.
At a meeting on Monday, many representatives have expressed their concerns about the air quality, too. One talked about his experience in Beijing. “After taking a taxi from the capital airport to my hotel, which took about an hour, I washed my nose and found the inside of my nose was black. We should ask ourselves this question：Why do we want to develop? It's for living a better life. Dirty air is definitely not a better life, ” he said.
China needs to develop its economy and invest (投资) in hightech. Every Chinese has a dream to make China stronger. But without blue sky, clean water and safe food, the achievements in the economy will become meaningless. Space technologies are not to be developed for building a base on Mars so that one day all human beings can move to the red planet because they have destroyed Earth.
What the public wants is a strong and beautiful China. The great efforts must be made to promote ecological progress and build a beautiful China. The words have shown the central government's determination to address the environment issue.

4.From the last two paragraphs we can infer that ________.
A.hightech can completely solve the problem of pollution
B.we must protect the environment while developing economy

[2016·湖北百校联考]We are surrounded every day by thousands of chemicals. These chemicals have been found to be safe-on their own. But are they still “safe” if mixed with other chemicals? That's the big question.
On its own, each chemical seems harmless. But in combination with other chemicals, they may become deadly. That is the finding of a two-year study by a high-profile task force of scientists. The task force was told to investigate the cancer-causing possibility of chemical mixtures.
Linda Gulliver was one of 174 scientists on the task force. Their job was to study the cancer-causing potential of 85 chemicals. All 85 are said to be common in the environment.
Ms Gulliver explains that chemicals have the potential to form dangerous mixtures. Even simple minerals can become dangerous when mixed with chemicals found in plastics or beauty products. While the chemicals are safe on their own. She says, the researchers found that many chemical compound cause cancer in human cells.
Working in groups, the scientists explored how different chemical mixtures could lead to cancer. Ms Gulliver's team looked at the ability of different combinations to support the increase of malignant (恶性的) human cells.
She says the big issue-what she calls “the $ 64 million dollar question”-is, “Which common, everyday chemicals do people need to avoid?”
“The $ 64 million dollar question that everybody wants to ask is, ‘Which chemicals should we be looking out for?’ And the answer to that is, ‘We don't know yet.’”
She says the current way to identify whether chemicals cause cancer is to test them one at a time. This method leads, she adds, to a long list of supposedly “safe” chemicals. She and her team say that approach needs to change.
“We definitely need certain research ... to find out what mixtures of chemicals would be more harmful than others; what groups of chemicals, when together, would produce more harmful effects. And at the moment, that is not known.”
本文讲述的是一种新的发现：单独看来无害的化学物质，可能与另一物质产生化学反应并会产生致癌物质。这项研究会不断地进行下去。
5.The purpose of the researchers' work is ________.
A.to find ways to protect human cells
B.to study the character of the chemicals
C.to study the cancer-causing possibility of mixtures
D.to study how deadly the chemicals in our homes are
答案：C 细节理解题。根据第三段的描述可知，研究的对象是造成癌症的可能的混合物。
6.According to Ms Gulliver's words, their research work is ________.
A.still limited
B.completely successful
C.practical to other researchers
D.not well received
答案：A 推理判断题。根据第六段和第七段Ms Gulliver所说的话可以判断对这些物质的不确定性，因而可推知答案是A。
7.What's the best title of the passage?
A.Chemicals are everywhere
B.Chemicals can lead to cancer
C.What is in chemicals in our daily life?
D.Mixture of safe chemicals may cause cancer
答案：D 主旨大意题。根据第一段中的几个问题“are they still ‘safe’ if mixed with other chemicals? That's the big question.”可知。
8.What can be inferred from the passage?
A.Harmful chemicals are throughout our homes.
B.Scientists know which mixture does harm to our health.
C.Researchers have quick approaches to studying the chemicals.
D.It is hard to tell what mixture of chemicals is harmful.
答案：D 推理判断题。根据文章最后一段，专家所描述的“...what groups of chemicals, when together, would produce more harmful effects. And at the moment, that is not known.”可知答案。
1.surround vt. 包围;围绕 2.mixture n. 混合物
3.avoid vt. 避免;逃避 4.identify vt. 辨别
5.harmful adj. 有害的
1.in combination with 与……结合
