马鞍山市2014高考英语阅读理解、动词短语精讲讲练（31）及答案

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 energy for our planet. It causes the 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. 64. 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 65. Only a small part of the Sun’s energy reaches the Earth’s surface because most of it is________. 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 66. 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

参考答案64 CC A **************************************************结束

When I was small and my grandmother died, I couldn't understand why I had no tears. But that night when my dad tried to cheer me up, my laugh turned into crying. So it came as no surprise to learn that researchers believe crying and laughing come from the same part of the brain. Just as laughing has many health advantages, scientists are discovering that so, too, does crying. Whatever it takes for us to reduce pressure is important to our emotional (情感的) health, and crying seems to work well. One study found that 85 percent of women and 73 percent of men report feeling better after crying. Besides, tears attract help from other people. Researchers agree that when we cry, people around us become kinder and friendly and they are more ready to provide support and comfort. Tears also enable us to understand our emotions better; sometimes we don't even know we're very sad until we cry. We learn about our emotions through crying, and then we can deal with them. Just as crying can be healthy, not crying—holding back tears of anger, pain or suffering—can be bad for physical (身体的) health. Studies have shown that too much control of emotions can lead to high blood pressure, heart problems and some other illnesses. If you have a health problem, doctors will certainly not ask you to cry. But when you feel like crying, don't fight it. It's a natural and healthy emotional response. 67. Why didn't the author cry when her grandmother died? A.
