What are the advantages and disadvantages of greenhouse technology?

There are many benefits of using greenhouses.Firstly,by using it,the productivity of the crop is increased considerably.Secondly,a superior quality can be obtained as they are grown under a better controlled environment. Thirdly,the percentage of germination of seeds is high in greenhouses.Finally,greenhouses allow an effective control of pests and diseases as the growing area is enclosed.
However,it has many disadvantages.On the one hand,greenhouses require a lot of work and constant maintenance.On the other hand,it is expensive to construct since gardeners will spend more money to buy a prefabricated greenhouse or to build a greenhouse than to plant directly in the ground or containers.Also,if Gardeners want to build their own greenhouses,they must pay highly for construction materials and sometimes,for additional labour. Moreover,greenhouses needs more space and homeowners need a very large space in their backyards or gardens for the greenhouse.Finally,the maintenance of the equipments used in greenhouses necessitates a lot of money and control.

Which of the following is not a disadvantage the greenhouse technology brings?
A:Greenhouses need constant care.
B:Building a greenhouse costs a lot.
C:The equipment used in greenhouses is cheap.
D:More labour is sometimes needed for greenhouse work.

Around 45%of the UK's carbon dioxide emissions come from the energy people use every day-at home and when they travel.In order to generate that energy,fossil fuels(coal oil,and gas)are burnt,and these produce greenhouse gases-in particular carbon dioxide(CO2).Car emissions are a major problem, but the truth is that more CO2 comes from the energy used at home.The average household creates around
five and a half tonnes of CO2 a year,and it is the same CO2 that is changing the climate and damaging the environment.
CO2 and various other gases wrap the earth in an invisible blanket helping to prevent heat from escaping.Without this greenhouse effect,the average temperature on Earth would be around-18℃， compared with the current average of around+15℃．The composition of this blanket of gases has remained relatively constant for many thousands of years.However,since the industrial revolution began around 200 years ago,people have been burning increasing amounts of fossil fuels,thus releasing more CO2 and other greenhouse gases in the process.This has increased the heating effect of the blanket,trapping more of the sun's energy inside the Earth's atmosphere in turn the Earth's temperature has increased more rapidly in a shorter period of time than it has for thousands of years.
In 2008,the total UK CO2 emissions were 533 million tonnes.27%(144 million tonnes)of those emissions came from the energy used to heat,light,and power homes.Transport emissions caused by passenger cars,buses and motorcycles accounted for a further 16%(87 million tonnes)of the UK's CO2 emissions.These figures show that a significant amount of CO2 results from ordinary citizens carbon footprint in their daily activities and lifestyle.
The effects of climate change can be seen all around us.Weather patterns are becoming more and more fractured and uncertain,and over the last century trends in warm weather have become increasingly common.In the UK in the last 40 years,winters have grown warmer,with much heavier rainfall.One of the clearest shifts over the last 200 years is towards summers that are hotter and drier,causing pervasive（普遍的）water shortages.Recent years have been the hottest since records began and during August 2003,the hottest ever outdoor temperature in the UK was recorded-38.5℃．

What is the author's opinion about the level of CO2 emissions in the UK?
A:The majority of CO2 emissions come from motorized transport.
B:CO2 emissions may cause climate change in the future.
C:More CO2 emissions come from homes than from cars.
D:The average citizen does not create much CO2.

第3题：

A greenhouse is a building made of glass which is used for keeping plants when the outside temperature is low. In a similar way there are several gases in the atmosphere which trap(捕捉)the heat produced by the sun and prevent it from escaping. These gases are known as"greenhouse gases"，and the way in which they trap heat in the atmosphere is called the "greenhouse effect". This is not simply air pollution. Most of the main greenhouse gases exist naturally in small amounts in our atmosphere, and without them earth would be 30 degrees colder and human life would not exist. In other words, the greenhouse effect is a natural course which is to some degree helpful to us.

The problem is that in the last century and a half, we have been putting too many of these gases into the earth's atmosphere by burning large quantities of coal and oil and by cutting down forests. The rapid increase in greenhouse gases is making the world warmer. The world's temperature has already gone up by half a degree this century, and the sea level has risen by 10 centimetres. If the amount of carbon dioxide(二氧化碳)in the atmosphere doubles, there will probably be a rise in the earth's temperature of between 1 and 4 degrees. This may seem a small increase, but it would be enough to cause major changes in geography and agriculture. Large areas of the world would be flooded, and some areas would become dry and unable to produce crops. It is important, too, to consider that there may be a delay of about 30 years in the greenhouse effect. This means that we are probably experiencing only now the effect of the gases put into the atmosphere before the 1960s. Since then, our use of these gases has greatly increased.

1. The"greenhouse effect"means _____.

A. the way in which gases are used for keeping plants warm

B. a natural course which is some degree helpful to us

C. the way"greenhouse gases"trap heat on the earth

D. the whole course in which greenhouse gases prevent heat

2. If there were no greenhouse effect, _____.

A. no plants would grow on our planet

B. earth would be thirty degrees colder

C. man could not live on the earth

D. All of the above answers are correct

3. Which of the following is NOT true? _____

A. Burning too much coal and oil produces lots of greenhouse gases.

B. It has become warmer on the earth now than in the past.

C. Gases put into the atmosphere now will affect the earth years later.

D. The temperature in a greenhouse is as high as that in the atmosphere.

4. Suppose the earth's temperature rose by 3 degrees, _____.

A. great harm would be done to mankind

B. the sea level would go by 10 centimetres

C. all the land in the world would be flooded

D. crops would be unable to grow on the earth

5. This passage mainly deals with _____.

A. the concept(概念)and harm of greenhouse effect

B. the relation between greenhouse gases and man

C. the concept and change of greenhouse effect

D. the effect of the rise of the earth's temperature

High Stress May Damage Memory

According to a report issued in May 1998,elderly people who have consistently high
blood levels of cortisol (皮质醇）don't score as well on memory tests as their peers with
lower levels of the stress hormone. What's more,high levels of cortisol are also associated
with shrinking of the hippocampus（海马区）,a region of the brain that plays a key role in
learning and memory.
The findings suggest that even cortisol levels in the normal,"healthy"range can
actually accelerate brain aging.
The study results"now provide substantial evidence that long-term exposure to adrenal
(肾上腺的）stress hormones may promote hippocampal aging in normal elderly humans",
write Nada Porter and Philip Landfield.Cortisol is a hormone released in response to stress
by the adrenal glands（腺）,which sit on top of the kidneys(肾）.
Over a 5-to 6-year period,Dr. Sonia Lupien and his colleagues measured 24-hour
cortisol levels in 51 healthy volunteers,most of whom were in their 70s.
The researchers tested the volunteers' memory on six people in the increasing/high
category and five people in the decreasing/moderate group.The groups did not differ in
tests of immediate memory,but the increasing/high cortisol group had other memory
problems compared with those in the decreasing/moderate group.
The researchers also found that the total volume of the hippocampus in those in the
increasing/high group was 14% lower than those in the decreasing/moderate group,
although there were no differences in other brain regions.
The results suggest that“…brain aging can be accelerated by levels of adrenal
hormones that are not generally regarded as pathological（病态的）and that variation within
this normal range is related to variation in the rate of brain aging",write Porter and
Landfield."This further suggests that chronic stress may accelerate the worsening of the
hippocampus."

When the levels of cortisol go high,the hippocampus
A:may expand.
B:may shrink.
C:may disappear.
D:may function better.
