Mulch is a protective cover of material that is spread on top of soil.It is usually made out of organic material, like crop waste.Farmers may keep the remains of maize or other crops on top of the soil.This creates mulch on the soil surface.The plant remains help protect the soil against wind and water damage.Mulching is one of the best things people can do for their plants.It also helps keep the soil from getting dry, and reduces the need for watering plants.It also limits temperature changes in the soil.And it stops unwanted plants, or weeds，from growing.

Organic mulch improves the condition of soil.As the mulch breaks down, it provides material which keeps the soil from getting hard.This improves the growth of roots and increases the movement of water through the soil.It also improves the ability of the soil to hold water. Organic mulch contains nutrients for plants.It also provides a good environment for earthworms and other helpful organisms in the soil.

It is easy to find organic mulch materials.Cut?up leaves and small pieces of tree bark can be used.Grass cuttings are also a good mulch for plants. Mulch from newspapers works well in controlling weeds.

The best time to add mulch depends on your goal.Mulch provides a thick barrier between the soil and the air.This helps to reduce temperature changes in the soil. As a result，mulched soil will be cooler than other soil in the summer.In winter, the mulched soil may not freeze as deeply as other soil.The best time is after the ground has frozen, but before the coldest weather arrives.Spreading mulch before the ground has frozen may attract small animals searching for a warm place to spend the winter.Delaying the spreading should prevent this problem.The animals will probably find another place to live.

1.The author tells us the following EXCEPT________.

A．what mulch is and its benefits

B．the best time to add mulch

C．what can be mulched on the soil surface

4.The main idea of Paragraph 2 is that organic mulch can________.

A．improve the condition of soil

B．improve the ability of the soil to hold water

It's hardly surprising that weather is a favorite topic for so many people around the world—it affects where we choose to live, what we wear, our moods, and perhaps even our national characteristics.Studies have shown that changeable weather can make it difficult to concentrate, cloudy skies slow down reaction, and hot，dry winds make many people bad?tempered.

If you live in a place like Britain, where the weather seems to change daily if not hourly，you could be forgiven for thinking that the weather is random.In fact the weather is controlled by systems which move around areas of the globe.In the UK the weather depends on depressions (低壓氣流), often called lows，and anticyclones(反氣旋)，also known as highs.These systems start in the Atlantic Ocean, and make their way across the British Isles from the west to the east.Highs bring sunny weather, while lows bring rain and wind.In modern times, human activities seem to be altering weather patterns.Gases produced by heavy industry change the temperature of the earth's surface，and affect cloud formation.Some researchers say that factories in Europe and North America may have been one of the causes of the droughts in Africa in the 1980s.

The human race has always tried to guess the weather，especially in areas of the world where there are frequent changes.Traditional rhymes point to early attempts to identify weather patterns; popular poems include：

Red sky at night, shepherd's delight；red sky in the morning, shepherd's warning.

Flies will swarm before a storm.

Rain before 7，clear by 11.

While folk wisdom can provide a guide to help forecast weather, today's methods of prediction increasingly rely on technology.Satellites, balloons，ships, aircrafts and weather centers with sensitive monitoring equipment, send data to computers.The data is then processed, and the weather is predicted.However，even this system cannot predict weather for longer than about a week.

1.When weather keeps changing，________.

A．people become bad?tempered

B．people's reaction slows down

C．people find it hard to focus on their work

D．people find it easy to focus on their work

2.The weather in Britain is________.

A．random　B．moist

C．depressing　D．satisfying

3.According to a traditional rhyme, if there is a red sky at night, the next day will be________.

A．windy　B．rainy

C．fine　D．snowy

4.Which of the following statements is TRUE?

A．Anticyclones often bring rain and wind.

B．Weather forecasting has been done for a long time.

C．Weather could never be predicted.

D．Modern methods of weather prediction are developed from folk wisdom.

5.What is mainly talked about in the second paragraph?

A．Changes in weather.

B．Weather in Britain.

C．African droughts.

D．Research on weather.
