We experience different forms of the Sun’s energy every day. We can see its light and feel its warmth. The Sun is the major source of evaporation (蒸发) of water from the oceans and lakes. Sunlight also provides the energy used by green plants to make their own food. These green plants then provide food for all organisms (生物) on the Earth.

Much of the energy that comes from the Sun never reaches the Earth’s surface. It is either reflected or absorbed by the gases in the upper atmosphere. Of the energy that reaches the lower atmosphere, 30% is reflected by clouds or the Earth’s surface. The remaining 70% warms the surface of the planet, causes water to evaporate, and provides energy for the water cycle and weather. Only a tiny part, approximately 0.023%, is actually used by green plants to produce food.

Many gases found in the atmosphere actually reflect heat energy escaping from the Earth’s surface back to the Earth. These gases act like the glass of a greenhouse in that they allow energy from the Sun to enter but prevent energy from leaving. They are therefore called greenhouse gases.

When sunlight strikes an object, some of the energy is absorbed and some is reflected. The amount reflected depends on the surface. For example, you’ve probably noticed how bright snow is when sunlight falls on it. Snow reflects most of the energy from the Sun, so it contributes to the low temperatures of winter. Dark-coloured surfaces, such as dark soil or forest, absorb more energy and help warm the surrounding air.

According to the passage, the root cause for weather changes on the Earth is ______.

A. the atmosphere surrounding the Earth

B. water from oceans and lakes

C. energy from the Sun

D. greenhouse gases in the sky

Only a small part of the Sun’s energy reaches the Earth’s surface because most of it _______________.

A. absorbed by the clouds in the lower atmosphere

B. reflected by the gases in the upper atmosphere

C. lost in the upper and lower atmosphere

D. used to evaporate water from the oceans and lakes

We learn from the passage that _______________.

A. all living things on the Earth depend on the Sun for their food

B. a forest looks dark in winter because it absorbs solar energy

C. only 0.023% of the energy from the Sun is made use of on the Earth

D. greenhouse gases allow heat energy to escape from the Earth’s surface

A famous American John Muir said in 1898: “The Grand Canyon… as unearthly (神秘的) in the color and grandeur (壮观) of its architecture as if you had found it after death on some other star.” Like Muir, those of us who stand along the rim are prompted to wonder about the unearthliness and the forces that created and are still changing this place.

After more than 100 years of studies, many things are still mysterious. Today visitors come by the thousands -- the great and simple of the earth -- all in a spirit of wonder. Travelers come from every state of the Union, from every country in Europe and Asia.

From the depths of the canyon comes welling silence. Seldom can you hear the roar of the river, for all sounds are swallowed in this gulf of space. “It makes one want to murmur.” A woman once whispered to her companion. This silence is not the silence of death; rather, it is a presence. It is like a great piece of music. But music made of man works up to a climax (高潮) and stops.

Now, visitors to the South Rim alone may number 18,000 in a single day. Some of that number will travel by mule train down Bright Angel Trail to the canyon's floor, cross the raging river by a suspension bridge (吊桥) and walk to the North Rim. Though the two rims face each other across only 12 miles, it is a journey of 214 miles by car from one to the other. Nor can you visit the North Rim except in summer; some 1,200 feet higher than the South Rim, it is snow covered much of the year except in July and August.

But there is no day that you may not visit the South Rim and find the sun warm on your face and the air perfumed with the incense (香气) of smoke from an Indian hearth (香炉). No wonder an American writer and journalist said, “I came here an atheist (无神论者), and departed a devout （虔诚的）believer.”

What is it that attracts so many travelers to the Canyon?

A. The unearthliness and the grandeur of its architecture.

B. The presence of American super stars.

C. The saying made by American writers and journalists.

D. The roaring of the river in the Canyon.www..ocm

What does the underlined word “simple” refer to?

A. peaceful stream B. land surface C. common people D. tamed animals

If you want to visit the North Rim from the South Rim, which of the following won’t be the way of traveling for you?

A. By train. B. By animal. C. By car. D. On foot.

The last sentence “I came here an atheist, and departed a devout believer.” implies that ______.

A. natural wonders such as the Canyon have some effect on human activities

B. all visitors to the Grand Canyon are God believers

C. atheist can’t see the magnificence of the Grand Canyon

D. the Grand Canyon is an unearthly sight that only God could create

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 run 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 meters 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, warming 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．
【小题1】Which of the following is true according to the first two paragraphs?

A．Arian de Bondt got his idea from his boss．

B．Large, flat, black surfaces need to be built in cities．

C．The Dutch engineer's system has been widely used．

D．Heat can also be collected from asphalt roads．

【小题2】For what purpose are the diving pipes used?

A．To absorb heat from the sun．	B．To store heat for future use．
C．To turn solar energy into heat energy．	D．To carry heat down below the surface．

【小题3】From the last paragraph we can learn that ________．

A．some pipes have to be re-arranged in winter

B．the system can do more than warming up the building

C．the exchangers will pick up heat from the street surface

D．less heat may be collected in winter than in summer

【小题4】What is most likely to be discussed in the paragraph that follows?

A．What we shall do if the system goes wrong．

B．What we shall do if there are no asphalt roads．

C．How the system cools the building in summer．

D．How the system collects heat in spring and autumn．

Human beings are the most intelligent of all animals because we are gifted with the ability to think and reason logically. Scientists and even common people with special intelligence have made a lot of inventions and contributions to modern lifestyle in the past. "Houses" have been the most popular area for discoveries and inventions in the past and even now.

Many household items have been the result of inventions of people who desired better functioning of the existent products. Every individual has intelligence and if it is used properly for the right purpose it leads to invention of a new tool or device. Many new household inventions are made almost every day and there are specific companies, which particularly keep a record of all these inventions.

A lot of inventions have been made recently in the household field. These products are patented（专利的）and have trade mark licenses（许可）. The patented sliding cinch is a very simple but effective method to prevent shoulder stress and injury for those who work before computers all day long. Vanity PC is a type of computer furniture that specifically hides all the computer wires and keeps a clean and good look. All the outdoor dust, mud and snow can be kept out of the house by installing（安装）the dirt drain（排水管）at the entrance of the door. Another important invention is the automatic toilet night-light, in which a small light starts when the lid of the toilet seat is opened and closes as soon as the lid（盖子）is closed.

These are some of the new household inventions invented mostly by common people. Thus, a variety of new household items are invented every day, which helps in a better functioning of household chores（家务）and in a more useful manner.
