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 (蒸發) 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

Damage to Ozone Layer Gets Worse
In the middle of winter, when snow is falling in many parts of the United States, scientists have sounded a warning to people who plan to spend many hours in the sun this summer．The warning: The sun's summertime rays are more dangerous than once thought.
A team of scientists from 80 nations recently reported to the United Nations that a layer of ozone（臭氧層）in the atmosphere, which protects humans from harmful levels of ultraviolet（紫外線）radiation, will be thinner over the United States this summer．The thinner layer allows more ultraviolet rays from the sun to reach Earth．The extra amount of ultraviolet radiation could cause an increase in the number of cases of skin cancer.
Scientists first became concerned about the layer in the mid-1980s when a hole was discovered in the layer above Antarctica during the winter．The hole was caused in chemicals used in refrigerators and air conditioners．When these chemicals are sent out into the atmosphere, they produce gases that destroy the ozone.
Concern about the protective ozone layer rose more recently when data from satellites and ground stations showed that ozone levels were dropping over areas other than Antarctica．Low ozone levels were recorded in the spring and summer over the United States and over other populated areas in the world.
Although many countries have already begun stopping the use of ozone-destroying chemicals, the new findings are expected to advance the timetable for a total ban of the chemicals.
The scientists have observed the ozone layer ______．
A．since 1980 B．since last winter
C．for more than 20 years D．for about one year
The ozone layer in the atmosphere can ______.
A．do a lot of good to human beings in many ways
B．protect humans from diseases caused by bad weather
C．do a lot of harm to human beings in the summer-time
D．protect humans from harmful levels of ultraviolet radiation
Scientists first found that there was a hole in the ozone layer ______.
A．above Arctic during the winter in the mid-1980s
B．above Antarctica during the winter in the mid-1980s
C．over somewhere in the north of the equator in 1980
D．over the USA in the summertime in the mid-1980s
The damage to the ozone layer was caused by ______.
A．the changeable weather B．ozone-destroying chemicals
C．chemicals from refrigerators D．chemicals from air conditioners

It’s interesting that the arrival of snow has effect on people in different countries. For some countries it is an important happening to celebrate each year, while for others a catastrophe(災害) or even a wonder.
But there are countries between these two kinds that normally expect snow some time over the winter months, but never receive snow regularly or in the same quantities every year. Britain is one of them, for which the arrival of snow quite simply causes problems. Within hours of the first snowfalls, however light, roads are blocked, trains and buses have to stop in the middle of the way. Normal communication is affected as well: telephone calls become difficult and the post immediately takes more time than usual. And almost within hours, there are also certain shortages----bread, vegetables and other things-----not because all these things can no longer be produced or sent to shops, but mainly because people are frightened and go out and store up with food and so on…just for fear that something bad should happen.
But why does snow have this effect? After all, the Swiss, the Austrians and the Canadians don‘t have such problems. It is simple because there is not enough planning and preparation. We need money to buy equipment to deal with snow and ice. To keep the roads clear, for example, requires snow-ploughs(掃雪機) and machines to spread salt. The reason why a country like Britain does not buy snow-ploughs is that they are used for a few days in any one year, and the money could be more useful in other things such as hospital, education, helping the old and so on..
1.According to the writer, Britain is a country ________.
|
A．which has regular snow |
B．which is not well prepared for snow |
|
C．for which snow is a catastrophe |
D．for which snow is a wonder |
2.After a few hours’ snowing there are often some shortages of food because ______.
A. shops have closed down B. people buy as much as they can
B. farmers cannot produce any more D. people eat more vegetables in winter
3.The words "two kinds" in the passage mean the countries ______.
|
A．which have weather as yearly happening to celebrate or as rare(少見) weather |
|
B．which either have heavy snow or light snow |
|
C．to which snow either causes problems or no problems |
|
D．which either have snow-ploughs or no snow-ploughs |
