Sometimes, the simplest ideas are the best. For example, to absorb heat from the sun to heat water, you need large, flat, black surfaces. One way to do that is to build those surfaces specially, on the roofs of buildings. But why go to all that trouble when cities are full of black surfaces already, in the form of asphalt (柏油) roads?
Ten years ago, this thought came into the mind of Arian de Bondt, a Dutch engineer. He finally persuaded his boss to follow it up. The result is that their building is now heated in winter and cooled in summer by a system that relies on the surface of the road outside.
The heat-collector is a system of connected water pipes. Most of them ran from one side of the street to the other, just under the asphalt road. Some, however, dive deep into the ground.
When the street surface gets hot in summer, water pumped through the pipes picks up this heat and takes it underground through one of the diving pipes. At a depth of 100 metres lies a natural aquifer (蓄水层) into which several heat exchangers (交换器) have been built. The hot water from the street runs through these exchangers, warning the ground-water, before returning to the surface through another pipe. The aquifer is thus used as a heat store.
In winter, the working system is changed slightly. Water is pumped through the heat exchangers to pick up the heat stored during summer. This water goes into the building and is used to warm the place up. After performing that task, it is pumped under the asphalt and its remaining heat keeps the road free of snow and ice.

举一反三
A rainforest is an area covered by tall trees with the total high rainfall spreading quite equally through the year and the temperature rarely dipping below l6℃．Rainforests have a great effect on the world environment because they can take in heat from the sun and adjust the climate．Without the forest cover，these areas would reflect more heat into the atmosphere，warming the rest of the world. Losing the rainforests may also influence wind and rainfall patterns，potentially causing certain natural disasters all over the world．
In the past hundred years，humans have begun destroying rainforests in search of three major resources(资源): land for crops，wood for paper and other products，land for raising farm animals．This action affects the environment as a whole．For example，a lot of carbon dioxide(二氧化碳) in the air comes from burning the rainforests．People obviously have a need for the resources we gain from cutting trees but we will suffer much more than we will benefit.
There are two main reasons for this．Firstly，when people cut down trees，generally they can only use the land for a year or two．Secondly，cutting large sections of rainforests may provide a good supply of wood right now，but in the long run it actually reduces the world’s wood supply．
Rainforests are often called the world’s drug store．More than 25％ of the medicines we use today come from plants in rainforests．However，fewer than l％of rainforest plants have been examined for their medical value．It is extremely likely that our best chance to cure diseases lies somewhere in the world’s shrinking rainforests．
小题1:Rainforests can help to adjust the climate because they ．
| A．reflect more heat into the atmosphere |
| B．bring about high rainfall throughout the world |
| C．rarely cause the temperature to drop lower than l6℃ |
| D．reduce the effect of heat from the sun on the earth |
| A．We will lose much more than we can gain． |
| B．Humans have begun destroying rainforests． |
| C．People have a strong desire for resources． |
| D．Much carbon dioxide comes from burning rainforests． |
| A．we can get enough resources without rainforests |
| B．there is great medicine potential in rainforests |
| C．we will grow fewer kinds of crops in the gained land |
| D．the level of annual rainfall affects wind patterns |
| A．How to Save Rainforests | B．How to Protect Nature |
| C．Rainforests and the Environment | D．Rainforests and Medical Development |
According to a weather expert" s prediction, the atmosphere will be 3℃ warmer in the year 2050 than it is today, if man continues to burn fuels at the present rate. If this warming up took place, the ice caps in the poles would begin to melt, thus raising sea level several metres and severely flooding coastal cities. Also, the increase in atmospheric temperature would lead to great changes in the climate of the northern hemisphere (北半球), possibly resulting in an alteration of the earth"s chief food growing zones.
In the past, concern about a man-made warming of the earth has concentrated on the Arctic because the Antarctic is much colder and has a much thicker ice sheet. But the weather experts are now paying more attention to West Antarctic, which may be affected by only a few degrees of warming, in other words, by a warming on the scale that will possibly take place in the next fifty years from the burning of fuels.
Satellite pictures show that large areas of Antarctic ice are already disappearing. The evidence available suggests that a warming has taken place. This fits the theory that carbon dioxide warms the earth.
However, most of the fuel is burnt in the northern hemisphere, where temperatures seem to be falling. Scientists conclude , therefore, that up to now natural influences on the weather have gone beyond those caused by man. The question is: Which natural cause has most effect on the weather?
One possibility is the variable behavior of the sun. Astronomers at one research station have studied the hot spots and "cold" spots (that is, the relatively less hot spots) on the sun. As the sun rotates (使旋转), every 27. 5 days, it presents hotter or "colder" faces to the earth, and different aspects to different parts of the earth. This seems to have a considerable effect on the distribution of the earth"s atmospheric pressure, and consequently on wind circulation. The sun is also changeable over a long term: its heat output goes up and down in cycles, the latest trend being downward.
Scientists are now finding shared relations between models of solar weather interactions and the actual climate over many thousands of years, including the last Ice Age. The problem is that the models are predicting that the world should be entering a new Ice Age and it is not. One way of solving this theoretical difficulty is to assume a delay of thousands of years while the solar effects overcome the inertia (惯性) of the earth"s climate. If this is right, the warming effect of carbon dioxide might thus be serving as a useful opposed balance to the sun"s fading heat .
66. It can be concluded that a concentration of carbon dioxide in the atmosphere would_________.
A. mean a warming-up in the Antarctic
B. raise the temperature of the earth" s surface
C. prevent the sun"s rays from reaching the earth"s surface
D. explain the cause of great changes in the climate in the northern hemisphere
67.The article was written to explain ___________.
A. the greenhouse effect
B. the solar effects on the earth
C. the causes affecting weather
D. the models of solar-weather interactions
68. Although the fuel consumption is greater in the northern hemisphere, temperatures there seem to be falling. This is__________.
A. mainly because the levels of carbon dioxide are rising
B. partly due to changes in the output of solar energy
C. possibly because the ice caps in the poles are melting
D. only due to the effect of the inertia of the earth" s climate
69. On the basis of their models, scientists believe the opinion that__________.
A. the climate of the world should be becoming cooler
B. the new Ice Age will be delayed by the greenhouse effect
C. the man-made warming effect helps to increase the solar effects
D. it will take thousands of years for the inertia of the earth"s climate to take effect
70. If the assumption about the delay of a new Ice age is correct, ____________.
A. ice would soon cover the northern hemisphere
B. the greenhouse effect could work in favor of the earth
C. the best way to overcome the cooling effect would be to burn more fuels
D. the increased levels of carbon dioxide in the atmosphere could warm up the earth even more quickly
Expect a lot from your child, just not everything. Except for health and safety problems, such as drug use or careless driving; consider everything else open to discussion. If your child is unwilling to discuss something, don’t insist he tell you what’s on his mind. The more you insist, the more likely that he’ll clam up. Instead , let him attempt to solve（解决）things by himself. At the same time, remind him that you’re always there for him should he seek advice or help. Show respect for your teenager’s privacy （隐私）. Never read him his mail or listen in on personal conversions.
Teach your teenager that the family phone is for the whole family. If your child talks on the family’s telephone for too long, tell him he can talk for15 minutes, but then he must stay off the phone for at least an equal period of time. This not only frees up the line so that other family members can make and receive calls, but teaches your teenager moderation（节制）. Or if you are open to the idea, allow your teenager his own phone that he pays for with his own pocket money or a part –time job
68. The main purpose of the text is to tell parents _____________.

A. become excited B. show respect
C. refuse to talk D. seek help
70. What should parents do in raising a teenager according to the text?
A. Nor allow him to learn driving or take drugs
B. Give him advice only when necessary
C. Let him have his own telephone
D. Not talk about personal things with him
Text messages have exploded in popularity in recent years, particularly among young people. The wireless industry’s trade association, CTIA, estimates (估计) more than 48 billions text messages are sent each month.
The plan comes from the Warning Alter and Response Network Act, a 2006 federal law that requires improvement to the nation’s emergency alter system. The act tasked the Federal Communications Commission (FCC) with coming up with new ways to alter the public about emergencies.
“The ability to deliver accurate and timely warning and alters through cell phone and other mobile services is an important next step in our efforts to help ensure that the American public has the information they need to take action to protect themselves and their families before, and during, disasters and other emergencies,” FCC Chairman Kevin Martin said following approval of the plan.
Participation in the alter system by carriers — telecommunication companies — is voluntary, but it has received solid support from the wireless industry.
The program would be optional for cell phone users. They also may not be charged for receiving alters.
There would be three types of messages, according to the rules.
The first would be a national alter from the president, likely involving a terrorists attack or natural disaster. The second would involve “approaching threats,” which could include natural disasters like hurricanes or storms or even university shootings. The third would be reserved for child abduction (绑架)emergencies, or so-called Amber Alerts.
The service could be in place by 2010.
61. What is the purpose of the approval plan?
A. To warn people of emergencies via message.
B. To popularize the use of cell phone.
C. To estimate the monthly number of messages.
D. To promote the wireless industry.
62. The improvement to the present system is in the charge of ______.
A. CTLA. B. the Warning Alert and Response Network
C. FCC D. federal regulators
63. The carriers’ participation in the system is determined by _______.
A. the US federal government B. mobile phone users
C. the carriers themselves D. the law of the United States
64. Which of the following is true of cell phone users?
They must accept the alert service.
B. They may enjoy the alert service for free.
C. They must send the alerts to others.
D. They may choose the types of messages.
65. An alert message will NOT be sent if __________.
A. a child loses his way B. a university shooting happens
C. a natural disaster happens D, a terrorist attack occurs
66. Which of the following would be the best title for the test?
A. Cell Phone Alerts Protecting Students
B. Cell Phone Alerts by Wireless Industry
C. Cell Phone Alerts Natural Disasters
D. Cell Phone Alerts Coming Soon
