Soaring divorce rates around the globe are affecting the environment, American researchers suggested in a study released Monday.
Michigan State University researcher Jianguo “Jack” Liu and his assistant Eunice Yu said the increasing number of divorces leads to more households with fewer people and greater consumption of water and energy. They said housing units require space, construction materials and fuel to heat and cool, regardless of the number of inhabitants.
For example, in the United States in 2005, divorced households consumed an extra 73 billion kilowatt hours of electricity and 627 billion gallons of water. An additional 38 million extra rooms required heating and lighting that same year due to divorced households.
“A married household actually uses resources more efficiently than a divorced household”, Liu said. He said that in cohabitating households, people will watch the same television, share the air conditioning and heat and use the same refrigerator, all things that use energy at a regularly stable rate regardless of the number of users.
Liu said he was not condemning divorce, “Some people really need to get divorces.” He said that cohabitation was simply a more environmentally friendly option. Additionally, the researchers noted that trends other than divorce are also changing family living structures, such as the end of multiple generations of a family sharing a home and people remaining single longer.
“People’s first reaction to this research is surprise, and then it seems simple.” Liu said in a release, “But a lot of things become simple after research is done. Our challenges were to connect the dots and quantify their relationships. People have been talking about how to protect the environment and refuse climate change, but divorce is an overlooked factor that needs to be considered.”
He said the increasing energy demands caused by divorce should be considered by governments when they are creating environmental policies.
This passage is mainly meant to ____.
A. inform the reader of the increasing divorce in America
B. emphasize the importance of protecting the environment
C. tell people the effect divorce has on the environment
D. appeal to married people to keep their households
According to the passage, what’s the attitude of Mr. Liu towards divorce?
A. Supportive B. Objective. C. Indifferent. D. Unclear.

A. divorced households will promote the sales of products
B. married households are more willing to protect the environment
C. divorced households contribute more to the society’s development
D. divorce is not taken into account when people are protecting the environment

Computer programmer David Jones earned $ 150,000 a year designing new computer games, yet he cannot find a bank prepared to let him have a check card (信用卡). Instead, he has been told to wait another two years until he is 18.
He works for a small firm in Liverpool, where most young people of his age are finding jobs. David”s biggest headache is what to do with his money. Though he has high payment, he cannot drive a car, or get credit cards.(信用卡)
David got his job four months ago, a year after leaving school with six O-Levels(普通成绩) and working for a time in a computer shop. “I got the job because the people who run the firm knew I had already written some programs,” he said.
“I suppose $150,000 sounds a lot but I hope it will come to more than that this year.” He spends some of his money on records and clothes, and gives his mother $20 a week as he lives with his parents. But most of his spare time is spent working.
“Unfortunately, computing was not part of our studies at school,” he said. “ But I had been studying it in books and magazines for four years in my spare time. I knew what I wanted to do and never considered staying on at school. Most people in this business are fairly young, anyway.

A solar pump(太阳能水泵 ) was built in a desert small village. The pump used the deserts most common resource – sunlight, to increase its greatest need, water. Solar collectors were used to collect the sun’s rays. Flat collectors were used instead of concave (凹的) collectors. Flat collectors can be still and do not have moving parts, which can be broken in sandstorms. The system used the 20C temperature difference between the solar collectors and the ground water to work a steam engine which pumped water from under the ground.
Some of the social effects of the new pump were planed for. Children aged 6—15 used to meet the old men to receive the informal education there. In order to replace this, a school was also included in the project. But the project had not considered the traditional power structure of the village. As soon as the foreign experts left, the two richest men in the village took control of the pump and started selling water to everyone else. The result was that the majority of the people were poorer than before.

Mountain High and Annie"s Song have become very popular. But less than thirty years ago, John Denver was a young man with little more than a fine voice, a guitar, and a dream. Growing up in conservative (保守的) family, he was not believed to drop out of college and head to Los Angeles, where the music scene was flowering. Nor was he believed to succeed.
In Take Me Home, John Denver talked about the story that shaped his life, with the story of the rich inner journey of a shy Midwestern boy. With honesty and cleverness, he wrote about his childhood, the feeling of moving to Los Angeles as the 60s came, his first lucky breaks, his first songwriting success with leaving on a Jet Plane and finally got a world fame.
He also wrote about his relationship with his first and second wife, as well as his parents, his children, his partners through his life and his friends.

China is going green.In order to reduce air pollution and oil shortages, carmakers have announced their plans to develop hybrid vehicles (混合燃料汽车) for the Chinese market.Toyota’s hybrid car Prius will be ready to drive in China this week.Let’s have a look at the new car.
Any vehicle is a hybrid run on a rechargeable battery and gas.Hybrid cars have special engines, which are smaller than traditional gas engines.The gasoline engine provides 99 percent of the power when the car is going at a steady speed. A specially designed battery motor provides extra power for running up hills or when it needs to speed up.
Step into a Prius, and turn on the engine.The first thing you notice is that it is quieter than a traditional car.At this point, the car’s gas engine is at rest.The electric motor will provide power until the car reaches about 24km/h.If you stay at a low speed, you are effectively driving an electric car, with no gas being used, and no waste gas given off.
The computer decides when to use the gas engine, when to go electric, and when to use a combination of the two.If you go over 24km/h, when you step on the gas pedal (油门), you are telling the computer how fast you want to go.
The electric motor recharges automatically using a set of batteries.And when driving at a high speed, the gas engine not only powers the car but also recharges the batteries.When you use the brake, the electric motor in the wheels will work like a generator (发电机) to produce electricity to recharge the batteries.As a result, the car’s batteries will last for around 200,000 miles.
66.The underlined sentence probably means ________.
A.there will be more and more green land in China
B.China’s new cars are combinations of different green models
C.China is still young and lacking in experience
D.the environment is getting better in China
67. What is the most important feature of hybrid cars?
A. They are powered by both a rechargeable battery and gas.
B. They have smaller engines than traditional gas ones.
C. They only use 99 percent of their power to run up hill.
D. They are much quieter than traditional cars.
68. We can know from the story that ________.
A. the gas engine recharges the batteries as well as powering the car
B. using the brake suggests that the gas engine should work
C. the car’s batteries will last for around 200,000 miles without being recharged
D. the batteries can be recharged at any time you want
69. The author writes the passage mainly to________.
A. announce plans to develop hybrid vehicles for the Chinese market
B. let people know how to save their gas when driving a car
C. teach people how to drive a hybrid car
D. introduce a new kind of “green” car
70.Which of the following statements is TRUE according to the text?
A.The hybrid car is environmentally friendly.
B.The hybrid car is unable to get itself recharged.
C.The hybrid car has been made in mass.
D.The hybrid car can decide what power to use
