After over 2,100 days of operation, the central route of the South-North Water Diversion Project,     1     (transfer) 30 billion cubic meters of water and benefitted more than 67 million people up to now. The route,     2     (send) water from the Danjiangkou Reservoir located in the upper and middle reach of the Hanjiang River to Henan, Hebei, Tianjin and Beijing, stretches a total     3     (long) of 1,432 kilometers.

When the project just kicked off, only 20 of the 42 sections     4     (evaluate) in the Danjiangkou Reservoir and its upper reaches met water quality standard, and some even failed to meet Grade V standard,     5     lowest in China’s classification. After the operation of the project, all sections have met standard. The water fetched 15 meters below the surface in the project’s reservoirs is     6     (drink).

Since the project     7     (launch) in 2005, the water sources of the project have been well protected, and sound ecological environment has been maintained. At present, the forest coverage in Henan’s Nanyang and Hubei’s Shiyan,     8     the reservoirs locate, stands at 40.5 percent and 66.7 percent, respectively. The improved ecology also lifted biodiversity. These regions are home     9     170 migrant birds and a number of valuable plants. The improved environment has led to booming local tourism, attracting numerous visitors and constantly expanding the service industry for local communities. The enhanced ecological conservation efforts not only have no impacts on local people’s livelihood, but also     10     (steady) increase their income.

3 . The twilight zone (朦胧地带) contains the largest and least explored fish stocks (储备) of the world’s oceans. Ranging from just below 200 metres to 1,000 metres deep, it is an interface between the well-studied sea life in the sunlit zone above and the ecosystems of the darkest territory below. It has a major role in removing carbon dioxide from the atmosphere and storing it for centuries or longer. The twilight zone is also known to the largest migration on Earth. Huge numbers of fishes and zooplankton (浮游动物) move hundreds of metres towards the surface each night to feed, before withdrawing back down at dawn.

Yet the zone is poorly understood — physically,     biogeochemically and ecologically. Even the number of organisms that live there remains a mystery, let alone their diversity and function.

It is alarming, then, that this vast ocean domain is at risk in three ways-even before any of the potential consequences are understood. First, the world’s growing population has an increasing need for food. Second, sea-floor mining for minerals and metals could release waste into the region. And   third, climate change is varying temperature, acidification and oxygen levels in ways that are likely to affect life there.

The twilight zone is hard Io study. Its organisms are difficult to sample and analyse, being thinly distributed, almost invisible and often fragile. They also live at pressures of up to 100 atmospheres, which poses problems for laboratory-based investigations.

Critics might argue that walers near coasts and above shelves are more deserving of study, given the huge environmental pressures there, as well as their importance to societies. And, of course, they need attention. Sadly, however, it is too late to avoid widespread environmental damage to these inshore regions. Instead, research efforts and local policies must aim at minimizing the worst effects.

By contrast, the twilight zone is almost left in its original condition. Moreover, the majority of it lies beyond national administration. This makes it of common interest and responsibility, and means that global agreement is necessary to manage it.

1. What can we learn about the twilight zone?

A．It has the least fish stocks.

B．It reduces atmosphere’s carbon dioxide.

C．It lies at the bottom of sea.

D．Il is located above the sunlit zone.

2. What does Paragraph 3 mainly tell us?

A．Where global warming leads us.

B．Why high food consumption arises.

C．How the twilight zone is threatened.

D．What impacts pollution has on ocean.

3. What does the underlined word “it” in the last paragraph refer to?

A．The twilight zone.	B．The inshore area.
C．Its original condition.	D．National administration.

4. Which statement does the author agree with?

A．International cooperation is essential.

B．Inshore regions deserve more attention.

C．Global agreement has been reached.

D．Study on the twilight zone is out of the question.

4 . You might think people all over the United States have Wi-Fi----wireless Internet service---and mobile phones. But there is no such service in Green Bank, West Virginia, a tiny town four hours from the U.S. capital, Washington D.C. Fewer than 150 people live in Green Bank, which has two churches, an elementary school and a public library. It is also home to the largest radio telescope in the world.

There is a ban on Wi-Fi in Green Bank, along with anything else that can create electromagnetic(电磁的)waves. Officials say the waves could disturb the signals the telescope receives.

For many American, a visit to Green Bank is a little like returning to the 1950s. To get there, you must read road signs---because there is no GPS service in the town. People can connect with the Internet through telephones, but wireless service is not allowed.

The observatory(天文台)is one of the largest employers in the area. The federal National Science Foundation(NSF)spends about ﹩8.2 million a year to operate the observatory, telescope and educational center.

Jonah Bauserman is a technician. If he supposes there is a signal that is not allowed in the zone, he drives to the house where the signal is coming from and checks it. But once a week, when the device is cleaned, some banned devices are allowed near it.

People in the town respect the work of the scientists. And they say they are happy to live without Wi-Fi and mobile phones. “You know, instead of sitting here on our phones and other devices we’re out fishing and hunting and going to each other’s houses.” Everyone knows each other and communication is almost always face-to-face.

1. What will you see when you pay a visit to Green Bank?

A．GPS service	B．Radio-controlled toys
C．Cell phone towers	D．Guide posts

2. What is Jonah Bauserman’s duty in his work?

A．Cleaning the telescope once a week.	B．Following signals from cell phones.
C．Protecting the telescope from being affected.	D．Listening for signals from outer space.

3. What is the attitude of the local people towards the telescope?

A．disapproving

B．favorable

C．controversial

D．indifferent

4. What may be the best title for this text?

A．A Better Life Without Wireless Devices

B．The Largest Radio Telescope in the World

C．An American Town Without Wi-Fi and Mobile Phones

D．Good Relationships Between People in an American Town

5 . 语法填空

For you, the "Clear and Bright" day that falls in every April might be no more than just another holiday — the fact that it comes with three days off school matters to most students     1    (much) than the fact that it is part of the 24 solar terms (二十四节气).

But this ancient system that Chinese people have used     2    (keep) track of the time of year was added to the UNESCO Representative List of the Intangible Cultural Heritage of Humanity (人类非物质文化遗产)on Nov. 30.

To be fair, the terms do sound old; they     3    (invent) thousands of years ago to offer weather information for agricultural     4    (activity). But the truth is     5    they still have an influence on our lives today, even if we don’t realize it most of the time. For example, people from     6    (north) China are in the habit of eating dumplings     7    the day of the winter solstice (冬至). And on the start of autumn, some treat     8    (they) to a big feast, especially of meat, something they call "putting on autumn weight", or tieqiubiao.

According to Chinese writer and academic Yu Shicun, the system is a philosophy of time,     9    applies to everything. And this means they are     10    (likely) to die out.
