[单项选择]One of the most pressing challenges that the United States—and indeed, the world—will face in the next few decades is how to alleviate the growing stress that human activities are placing on the environment. The consequences are just too great to ignore. Wildlife habitats are being degraded or disappearing altogether as new developments take up more land. Plant and animal species are becoming extinct at a greater rate now than at any time in Earth’s history. As many as 30 percent of the world’s fish stocks are overexploited. And the list goes on.
Yet, there is reason to have hope for the future. Advances in computing power and molecular biology are among the tremendous increases in scientific capability that are helping researchers gain a better understanding of these problems. Recent developments in science and technology could provide the basis for some major, and timely actions that would improve our understanding of how human activities affect the environment.
One
A. there are many more ways in which humans are hurting the environment.
B. environmental degradation is continuing unabated.
C. the total of animal and plant species facing extinction are too numerous to list.
D. in addition to fish, many other plant and animal species face over-exploitation by humans.

Passage One

Two pressing problems face the world: economic meltdown and global warming. Conveniently, a solution presents itself that apparently solves both: governments should invest heavily in green technology, thus boosting demand while transforming the energy business. This notion is gaining agreement around the world. Last month the United Nations called for a "Global Green New Deal". But it is in America that the idea is really taking off. The United States Conference of Mayors reckons that green investment should provide 2.5m jobs. The Centre for American Progress thinks $100 billion worth of spending in the area would provide 2m jobs. The new president tops both. Barack Obama proposes spending $150 billion over ten years, thus helping, he says, to create 5m jobs.
There is a historical parallel to this synergy between two worthy aim
A. It can provide millions of jobs with little money investment.
B. It can promote demand while reforming the energy industry.
C. It is helpful to the world’s peace and development.
D. It is well accepted by all of the countries in the world.

Passage One

Most people think of lions as strictly African beasts, but only because they’ve been killed off almost everywhere else. Ten thousand years ago lions spanned vast sections of the globe. Now lions hold only a small fraction of their former habitat, and Asiatic lions, a subspecies that spit from African lions perhaps 100 000 years ago, hang on to an almost impossibly small slice of their former territory.
India is the proud steward of these 300 or so lions, which live primarily in a S60-square-mile sanctuary (保护区). It took me a year and a half to get a permit to explore the entire Gir Forest-and no time at all to see why these lions became symbols of royalty and greatness. A tiger will hide in the forest unseen, but a lion stands its ground, curious and unafraid-lionhearted. Though they told mc in subtle ways when I got too close,
A. have killed off other lions
B. have descended from African lions
C. used to span vast sections of the globe
D. have lost their habitat
