The ecosystem is 1ike a chain．If any of the links are broken，the whole system is in danger．This is why wetland protection has been put high on the agenda in recent years．Zhao，vice―director of the State Forestry Administration，says nearly 60 percent of the country’s natural wetlands are still not under effective protection．Most Chinese people are ignorant about the importance of protecting the wetlands．
Ocean，forestry and wetlands are the three global ecological systems．Wetlands can conserve and purify water resources, prevent flooding and help protect the ecosystem. As well as ecological values， they can also offer economical returns．
In recent years，many wetlands have become farmland．Drawing too much underground water，hunting and fishing also ruin their ecological system．
Every year，the wetlands in the Sanjiang Plain of Northeast China provide habitat for birds．Local residents search the area for the birds’ eggs. They consider the eggs to be a natural gift. rather than wildlife that should be protected． If they were educated，perhaps this is one activity that could be brought to an end.
China is now ready to make a plan to save some of these areas．Some have been restored to raise awareness among the public．But these moves are not enough．There should be laws in place to provide legal support to the fight. Environment protection is a campaign which needs support from everyone in society．Education may be the first step.

查看习题详情和答案>>Thousands of people began pouring into Pennsylvania from other states. They wanted to buy lottery tickets（彩票）. The tickets cost only ＄0.9 each. But that small spending could bring them a reward of ＄90 million. That was the second largest lottery jackpot（积累奖金）in history.
More than 87 million tickets were bought for the Pennsylvania lottery drawing. Those who bought tickets had to choose seven numbers from l to 80. The chance of winning was one in 9.6 million, but that little chance certainly didn't affect ticket sales. In the last few days before the drawing, tickets were selling at the unbelievable rate of 500 per second.
Experts say many people buy lottery tickets because they just want to have a piece of the action. Others say the lottery is a stock market for poor people. It allows them to dream about wealth they'll probably never have.
But many people believe lotteries are no better than legalized（合法化的）gambling. Some critics note that most people who play are poor and may not be able to afford the tickets. There are also many addicts who take the game seriously. They may pour their life savings into lottery tickets. Some clubs have been formed to help them kick the habit.
Politicians like lotteries because they provide money that would otherwise have to come from new taxes. The profits from lotteries are usually used to pay for education or programs for senior citizens. But critics say this arrangement just allows states to legalize vice（恶习）, under the name of social progress. No matter whether you regard state lotteries right or not, you cannot refuse to accept their extreme popularity with many Americans.

查看习题详情和答案>>Boiler rooms are often dirty and steamy, but this one is clean and cool. Fox Point is a very new 47-unit living building in South Bronx, one of the city’s poorest areas. Two-thirds of the people living there are formerly (以前) homeless people, whose rent is paid by the government. The rest are low-income families. The boiler room has special equipment, which produces energy for electricity and heat. It reuses heat that would otherwise be lost to the air, reducing carbon emissions(碳排放)while also cutting costs.
Fox Point is operated by Palladia, a group that specializes in providing housing and services to needy people. Palladia received support from Enterprise Community Partners (ECP), which helps build affordable housing by providing support to housing developers.
ECP has created national standards for healthy, environmentally (环境方面) clever and affordable homes which are called, the Green Communities Standards. These standards include water keeping, energy saving and the use of environmentally friendly building materials. Meeting the standards increases housing construction costs by 2%, which is rapidly paid back by lower running costs. Even the positioning of a window to get most daylight can help save energy.
Michael Bloomberg, New York's mayor, plans to create 165,000 affordable housing units for 500,000 New Yorkers. Almost 80% of New York City’s greenhouse-gas emissions come from buildings, and 40% of those are caused by housing. So he recently announced that the city’s Department of Housing and Preservation and Development (DHPD) , whose duty is to develop and keep the city’s supply of affordable housing, will require all its new projects to follow ECP’s green standards.
Similar measures have been taken by other cities such as Cleveland and Denver, but New York’s DHPD is the largest city developer of affordable housing in the country.
What is the purpose of describing the boiler room in the first paragraph?
A．To explain the measures the city takes to care for poor people.
B．To suggest that affordable housing is possible in all areas.
C．To show how the environment-friendly building works.
D．To compare old and new boiler rooms.
What is an advantage of the buildings meeting the Green Communities Standards?
A．Lower running costs. B．Costing less in construction.
C．Less air to be lost in hot days D．Better prices for homeless people.
It can be learned from the text that_______________.
A．New York City is seriously polluted
B．people’s daily life causes many carbon emissions in New York City
C．a great number of people in New York City don't have houses to live in
D．some other cities have developed more affordable housing than New York City
What is the main purpose of this text?
A．To call on people to pay more attention to housing problems.
B．To prove that some standards are needed for affordable housing.
C．To ask society to help homeless people and low-income families.
D．To introduce healthy, environmentally clever-and affordable housing.
