    “The calm before the storm” is a very familiar expression. It is usually used to describe a peaceful period just before a very stressful situation or a tense argument. 1. They noted that before certain storms the seas would seem to become calm and the winds would drop.

But why is it often so calm before a storm? 2. According to US website HowStuffWorks, a calm period occurs because many storms, tornadoes and hurricanes draw in all the warm and damp air from the surrounding area. As this air rises into the storm clouds, it cools and acts as “ fuel for the storm ,like petrol in a car. “

Once the storm has taken all the energy it can from the air, it is pushed out from the top of the storm clouds and falls back down to ground level. 3. So once it covers an area, it causes a calm period before the storm.

4. First count how many seconds there are between a flash of lightning and a clap of thunder, roughly three seconds equal one kilometer. A good judgement is that if your count is below 30 seconds, you should seek shelter straight away.

However, due to the complexity of storm system ,calm doesn't always go first. So, your best bet is to keep yourself updated with weather reports for any predictions regarding a coming storm in your area. 5.

A. Science has given us the answer.

B. There is no definite answer to the question.

C. Weather reports sometimes cannot be trusted.

D. British sailors coined the phrase in the late l600s.

E. As the air declines, it becomes warm and dry, which is stable.

F. The Weather Network has a tip for working out how far away a storm is.

G. That's the most reliable way to predict the next display of nature's temper.

Benefits and Problems of Genetic Engineering

Plant breeding is the science of changing the characteristics of plants in order to produce desired ones. Genes in a plant are what determine what type of characteristics it will have. Plant breeders try to create a specific outcome of plants and potentially new plant varieties by changing the genes of the plants through breeding, which is making new plants from parents of different varieties or species.

Actually, plant breeding has been practiced for thousands of years, since near the beginning of human civilization. It is practiced worldwide by individuals such as gardeners and farmers and by professional plant breeders employed by organizations such as government institutions, universities, crop-specific industry associations or research centers. They have crossbred plants to create the new types of plants that are, for example, bigger, stronger, or more attractive.

Crossbreeding can take such a long time, however, and it is inaccurate. Now, we can change exact sections of Deoxyribonucleic acid (DNA), so the process is more accurate and faster. But people all over the world are arguing about its benefits and disadvantages. Some people use the technology to produce desired characteristics of plants and animals. Other people are concerned that the genetically engineered plants may harm the environment and worried that they may be dangerous for people to eat.

There are many reasons for changing plants in this way. International development agencies believe that breeding new crops is important for ensuring food security by developing new varieties that are higher yielding(高产的), disease resistant, drought tolerant or regionally adapted to different environments and growing conditions. For example, some genetically engineered plants can live through frost or draught. As a result, famers can make more profit because fewer plants will die.

Some genetically engineered plants are more nutritious. They have less fat, taste better or stay fresher than non-genetically engineered plants. This will allow people to buy better-quality fruit and vegetables.

Some genetically engineered plants can resist natural pests such as viruses or insects. This reduces the amount of chemical needed to kill pests, which is helpful to the environment.

However, genetically engineered plants can cause unexpected problems. Genetically engineered plants that resist pests may pass on that characteristic to a wild relative. This may cause the wild plant to spread fast, because pests are not naturally killing it.

Genetically engineered plants can also harm animals. A type of corn has been developed which kills a species of insect that destroys it. The pollen (花粉) from this corn, however, can also kill monarch butterflies—the most beautiful of all butterflies, which do not harm the corn.

To ensure the most adapted varieties are identified, advocates of organic breeding now promote the use of direct selection for many desired characteristics.

Genetic engineering is a very new science and we have a lot to learn about the good it can do and the damage it can cause. The main concern is that not enough tests are being done to ensure it is safe.
