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. divorced households will promote the sales of products

ays. 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.

A proven method for effective textbook reading is the SQ3R method developed by Francis Robinson. The first is to survey (the S step) the chapter by reading the title, introduction, section headings, summary., and by studying any graphs, tables, illustrations or charts. The purpose of this step is to get an overview of the chapter so that you will know before you read what it will be about. In the second step (the Q step), for each section you ask yourself questions such as "What do I already know about this topic?" and "What do I want to know?" In this step you also take the section heading and turn it into a question. This step gives you a purpose for reading the section. The third step (the first of the 3 R"s) is to read to find the answers to your questions. Then at the end of each section, before going on to the next section, you recite ( the second of the 3 R"s) the answers to the questions that formed in the question step. When you recite you should say the information you want to learn out loud in your own words. The fifth step is done after you have completed step 2, 3 and 4 for each section. You review (the last of the 3 R"s) the entire chapter. The review is done much as the survey was in the first step. As you review, hold a mental conversation with yourself as you recite the information you selected as important to learn. The mental conversation could take the form of asking and answering the questions formed the headings or reading the summary, which lists the main ideas in the chapter, and trying to fill in the details for each main idea.
小题1: The passage implies that the SQ3R method .

A．needs to be prove	B．leaves much to be desired
C．turns out to be practicable	D．cannot be used by every reader

B．four

C．five

B
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
