Passage 3

(09·安徽E篇)

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.

Passage 2

(09·安徽C篇)

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 rub 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.

B. to express the owners’ anger to the thief

C. to remind the thief of this conscience

2009年高考题

Passage 1

(09·上海C篇)

“Get your hands off me, I have been stolen,” the laptop, a portable computer, shouted. That is a new solution to laptop computer theft: a program that lets owners give their property a voice when it has been taken.

The program allows users to display alerts on the missing computer’s screen and even to set a spoken message. Tracking software for stolen laptops has been on the market for some time, but this is thought to be the first that allows owners to give the thief a piece of their mind.

Owners must report their laptop missing by visiting a website, which sends a message to the model: a red and yellow “lost or stolen” sign appears on its screen when it is started. Under the latest version(版本)of the software, users can also send a spoken message.

The message can be set to reappear every 30 seconds, no matter how many times the thief closes it.” One customer sent a message saying,’ You are being tracked. I am right at your door’,” said Carrie Hafeman, chief executive of the company which produces the program, Retriever.

In the latest version, people can add a spoken message. For example, the laptop’s speakers will say: “Help, this laptop is reported lost or stolen. If you are not my owner, report me now.”

The Retriever software package, which costs $29.95 but has a free trial period, has the functions of many security software programs .Owners can remotely switch to an alternative password if they fear that the thief has also got hold of the access details.

If a thief accesses the internet with the stolen laptop, Retriever will collect information on the internet service provider in use, so that the police can be alerted to its location.

Thousands of laptops are stolen every year form homes and offices, but with the use of laptops increasing, the number stolen while their owners are out and about has been rising sharply.

Other security software allows users to erase data remotely or lock down the computer.
