Support for renewable energy technology to figllt global warming is weakening in the face of
worldwide economic problems and the true scale of the carbon reductions required，a survey pub-
lished today has suggested．
Figures presented at the UN climate talks in Poznan，Poland，show that climate experts have
less faitll in alternative energy than they did 12 months ago．
The survey shows less support for wind energy，solar power，biofuels，biomass and hydrogen
energy as technologies with“high potential”to reduce carbon levels in the atmosphere over the next
25 years．
Eric Whan of Globesean，which carried out t}le survey of“climate decision makers”．said．
“As the climate crisis deepens they could be becoming less optimistic that individual technologies
may be able to solve the problem．’’
The survey，supported by groups including the World Bank，the United Nations Environment
Programme and the Pew Center for Global Climate Change，questioned l，000 senior figures across
governments，pressure groups and companies in 1 15 countries over the last few weeks．
Almost three—quarters of the experts agreed in the survey that“equitable(公平的，平等的)e—
eonomic growth and development and significant progress in combating(与…斗争)climate change
Call be achieved at the salne time．’’
Asked to rate the likely Success of low—carbon technologies in the mid—term，they showed
less confidence than a similar survey 12 months ago．Support for offshore wind farms，was down
61％from 65％last year.Solar electricity generation was rated as having high—potential by 66％of respondents，down from 74％．Support for hydrogen power was 32％，down form 36％in 2007．
The respondents also warned that a deep recession(衰退)would make a new global deal on climate harder to achieve．Some 44％agreed that the current economic crisis will significantly delay orcompromise the“achievement of effective climate change agreements．’’
72．Which of the following is NOT the alternative energy? ·
A．Wind energy． B．Solar power． C．Hydrogen energy．D．Conventional energy．
73．Which of the following altemative energy sees the most remarkable reduction in support'?
A．Offshore wind farms． B．Solar electricity．
C．Hydrogen power． D．Natural gas．
Why is support for renewable energy technology to fight dobal warming weakening?
A．The technology has no use at all．
B．People don’t want to use the technology．
C．Nothing can be done to reduce carbon levels in the atmosphere．
D．The current economic crisis iS to blame．
75．What’S the best title of the passage?
A．Experts Lost Faith in Renewable Technology B．Global Environment Is Worsening
C．Who Is to Blame f．0r tIle Environment D．What Can Be Done to Save the Earth
-
The global warming is more and more serious，for which human beings ________.
A．are blaming B．are to blame
C．are going to blame D．are to be blamed

Dangers from Outer Space
What is the greatest threat to life on our planet? Is it climate change? Shortages of food or water? Or might an altogether bigger danger come from somewhere further away: space?
We’re not talking about an attack by little green men here. Instead, how about being hit by a large falling star, beat by deadly universal rays or fried by the energy of an erupting star?
It wouldn’t be the first time that our Earth has had a rough ride over the last 3.7 billion years, with some disastrous events. The most famous mass extinction（灭绝）was 66 million years ago, when it’s widely believed that a meteorite（陨石）killed off the dinosaurs. A 110-mile-wide crater in Mexico with the same geological age supports this theory.
Believe it or not, this wasn’t the worst catastrophe in our planet’s history. That was when 96% of life was wiped out at the end of the Permian period, 252 million year ago. Scientists don’t know for sure why this happened, but any potential explanations carry with them the possibility that similar events could happen again.
Some experts believe that our Sun has a twin star which is too far away to observe directly. This huge sleeping star could twist the paths of orbiting icy rocks and cast them towards the rest of the Solar System.
Is this what happened 252 million years ago? Or is there instead, perhaps, a distant, ninth plant in our Solar System which pulls in passing comets（彗星）and sends them dashing our way?
The Sun that has given us the warmth is gradually turning into a deadly enemy. Like all stars, it is slowing dying, burning through its energy supplies. As it does so, it expands, and in about 2 billion years it will have grown so much that the heat will make life on planet Earth unbearable.
While all this sounds a little horrible, take comfort from the fact that the chance of being hit by a huge interstellar projectile（星际碰撞物）is unbelievably slim, and that 2 billion years is a very long time.
1.When did dinosaurs die out according to the passage?
A. 3.7 billion years ago. B. 252 million years ago.
C. 66 million years ago. D. 2 billion years ago.
2.Why was 96% of life destroyed at the end of the Permian period?
A. The cause is still unknown.
B. A huge falling star hit the earth.
C. A twin star cast icy rocks towards the Solar System.
D. A ninth planet pulled in passing comets.
3.What can we learn from the passage?
A. All stars will eventually run of energy.
B. Our planet will be attacked by little green men.
C. We will be fried by the energy of an erupting star.
D. A huge sleeping star will hit the earth in millions of years.
4.What is the author’s attitude toward the dangers from outer space?
A. Frightened. B. Relieved.
C. Worried. D. Doubtful.

Our planet is home to about seven billion people. Since the 1990s, population experts have predicted the number would grow to nine billion before it begins to slow down and possibly decrease.
But a new report predicts the world’s population is likely to increase to almost 11 billion by 2100. Based on the most modem statistical tools, the new report makes use of government records and considers expert predictions, including death rates, birthrates and international migration, or people moving across borders. The report says during the rest of this century, Africa’s population will grow from about 3.5 billion to 5.1 billion over the next 85 years.
John is director of the United Nations Population Division. He says that in the past, researchers thought population growth in Africa would be similar to that of other areas. They expected slower growth rates as birth control use became more widespread. But he says those ideas were wrong.
“The level of contraception use has continued to increase but slowly — more slowly than expected, and birthrate therefore has been falling less rapidly than expected, and the population therefore continues to grow somewhat more rapidly than we expected.
The new findings are based on a joint research project of the United Nations and the University of Washington,
The researchers believe the population of Asia will reach five billion by 2050. That is up from the current 4.4 billion. And then begin decline. The researchers also believe that North America, Europe, Latin America and the Caribbean area will have a total population of below one billion.
John says the pressure of feeding the rising population is likely to be less than that might be expected.
“The relatively good news is that the world has been winning the race between population growth and food production. If you look back historically over the last 50 years, certainly for the world as a whole and for many, most individual countries and regions, the increase in food production has outpaced the increase of population.”
1.Which area will experience the largest increase in population at the end of the century？
A. Asia. B. Africa.
C. Europe. D. North America.
2.“Contraception use” in the fourth paragraph refers to ________.
A. a method of expert predictions
B. a way of avoiding growth in population
C. a joint research into the rising population
D. a potential technology for food production
3.Why is the pressure of feeding the rising population less than expected according to John?
A. Expert predictions are not exactly like what the facts happen.
B. Birthrates have always been falling less rapidly than we expected.
C. The population grows less rapidly than population experts expected.
D. The increase in food production has outpaced the increase of population,
4.What can be inferred from the passage?
A. The world’s population will increase constantly.
B. The population of Asia will rise by 5 billion by 2050.
C. John is optimistic about feeding the rising population,
D. Population growth in Africa was much slower than expected.
