The oldest and most common source(来源) of renewable energy known to man, biomass is one of the most important forms energy production in the United States and elsewhere. Since such a wide variety of biomass materials is everywhere ---- from trees and grasses to agricultural and city ---- life wastes ----biomass promises to play a continuing role in providing power and heat for millions of people around the world.
According to the Union of Concerned Scientists(UCS), biomass is a kind of renewable energy source that produces no carbon dioxide(二氧化碳), because the energy it contains comes from the sun. When plant matter is burned, it gives off the sun’s energy. In this way, biomass serves as a sort of natural battery(电池) for storing the sun’s energy. As long as biomass is produced continuously ----with only as much grown as is used--- the “battery” lasts forever.
According to the Energy Information Administration, biomass has been one of the leading renewable energy sources in the United States for several years running through 2007, making up between 0.5 and 0.9 percent of the nation’s total electricity supply. In 2008----although the numbers aren’t all in yet----wind power probably took over first place because of the rapid development of wind farms across the country.
Producing power from biomass helps reduce some 11 million tons of carbon dioxide each year. Some homeowners also try to make their own heat by using biomass materials. Such practice may save homeowner’s money, but it also produces a lot of pollution. So, the best way is to encourage power plants to use it.

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 for500,000 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.

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
4.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.
I grew up in a house where the TV was seldom turned on and with one wall in my bedroom entirely lined with bookshelves, most of my childhood was spent on books I could get hold of. In fact, I grew up thinking of reading as natural as breathing and books unbelievably powerful in shaping perspectives (观点) by creating worlds we could step into, take part. in. and live in.
With this unshakable belief, I, at. fourteen, decided to become a writer. Here too, reading became useful. Every writer starts off knowing that he has something to say, but being unable to find the right ways to say it. He has to find his own voice by reading widely and discovering which parts of the writers he agrees or disagrees with, or agrees with so strongly that it reshapes his own world. He cannot write without loving to read, because only through reading other people’s writing can one discover what works, what doesn’t and, in the end, together with lots of practice, what voice he has.
Now I am in college, and have come to realize how important it is to read fiction (文学作品)．As a. law student, my reading is in fact limited to subject matter—the volume (量) of what I have to read for classes every week means there is little time to read anything else. Such reading made it all the clearer to me that I live in a very small part in this great place called life. Reading fiction reminds me that there is life beyond my own. It allows me to travel across the high seas and along the Silk Road, all from the comfort of my own armchair, to experience, though secondhand, exciting experiences that I wouldn't necessarily be able to have in my lifetime.
1. What can be inferred about the author as a child?

A. It helps him to realize his dream.
B. It opens up a wider world for him.
C. It makes his college life more interesting.
D. It increases his interest in worldwide travel.
4.Which of the following can be the best title of this text?

I am a Canadian girl aging 17 and I’ m mad about music. It is one of the most important thing in my life. I listen music whenever I can. I have a minidisk player, with it I can have access to music whether walking in the street or ride on the bike. At home, there is a CD player in my room, but music is on all the time. I like rock music better of all and my favorite band is Rolling stones. It so happened that there had a live concert of Rolling stones last Sunday. I went there and it was a great fun. I am also fond of classic music and I especial enjoy Beethoven when I’m doing my homework.
