D
Many disease researchers have warned that rising global temperatures could lead to more diseases. for example by allowing tropical diseases to expand their ranges into what are now mild regions. This is a particular fear for the diseases carried by insects such as malariac(疟疾) and
sleeping sickness.
But the reality is more complex, argues Kevin Lafferty. a disease ecologist. He argues that a warming climate could favour some diseases in certain regions while controlling them in others.
Lafferty does not deny that climate change might allow malarial mosquitoes to spread to new areas. However he believes that hotter and drier conditions may also get rid of mosquitoes from areas where they currently exist. If this were the case, he says. there would be little. if any, net
increase (净增长) in the risk of disease.
In addition, many mild regions such as southern Europe or the southern U.S. have good sanitation(卫生设备) and insect control programmes which, Lafferty says, would prevent diseases from becoming common even if climatic conditions were suitable.
Finally, he argues, climate change could wipe many species off the plant. Infectious pathogens(病原体) depend on their hosts for survival so they too may become endangered-especially if they,like malaria, rely on more than one host.
But Mercedes Pascual of the University of Michigan points out that there are large human populations in the east African highlands, just outside of the existing range of malarial mosquitoes.She said as temperatures rise, the mosquitoes will reach these areas. So the disadvantages will
outweigh the advantages of decreased risk elsewhere.
Most of the ecologists do, however, seem to agree on one point: predicting where a disease is going to go next involves far more than just considering climate. No matter what the results of the debate are, they all agree that health concerns should continue to play a critical role in climate policy and the debate shouldn"t be regarded as weakening the case for action against global warming.
53. According to Kevin Lafferty, climate change__________
A. will not increase the spread of insect-bome diseases
B. may not significantly increase the risk of disease in the whole world
C. will not affect the dry regions where sanitation is good
D. may not affect viruses that depend on more than one host
54. What does Mercedes Pascual think of Lafferty "s conclusion?
A. She disagrees with it. B. She supports it.
C. She is not sure ofit. D. She thinks it needs proving.
55. We may infer from the passage that ___________
A. climate is the only factor in the predictior of the spread of diseases
B. when making a climate policy one should take health into account
C. the debate mentioned in the passage furthers the debate on global warming
D. a policy should be made immediately to try to stop climate change
56. We can learn from the passage that ___________
A. all the disease researchers agree that climate change will spread disease
B. nothing can be done to stop the present global warming
C. scientists have found ways to stop the wild spread of disease
D. ecologists have different views on whether the global warming will spread diseases further

Fifteen years spent in the field of education has provided me with many treasured moments. One of the most unforgettable 36 when I was teaching second grade 10 years ago.
In May I decided to plan something special for the children; a Mother’s Day tea. We had put our 37 together to come up with ideas of how to 38 our mothers. We practiced singing songs, memorized poems and wrote cards. We decided to hold our tea the Friday before Mother’s Day. I was surprised and 39 to learn that every mother was planning to attend. I 40 invited my own mother.
Finally, the big day arrived. Each child lined up at our classroom door, 41 the arrival of his or her mom. 42 it got closer to starting time, I looked around and my eyes quickly found Jimmy. His mother hadn’t 43 up and he was looking upset.
I took my mother 44 the hand and walked over to Jimmy. “Jimmy,” I said, “I have a bit of problem here and I was 45 if you could keep my mother 46 while I’m busy.”
My mom and Jimmy sat at a table. Jimmy 47 my mom her treats, presented her with the gift I had made, just as we had 48 the day before. Whenever I looked over, my mother and Jimmy were in deep 49 .
Last year, I took a senior class on a field trip, and there was Jimmy, I had the students complete an outline of the day’s 50 and an evaluation of our trip. Then I collected the students’ booklets and checked them to see if 51 was completed. When I came to Jimmy’s 52 , he had written “Remember our Mother’s Day tea we had in second grade, Mrs, Marra? I do! Thanks for all you did for me, and thank your mother, too.”
I told him I really enjoyed what he had written. He looked rather embarrassed and 53 his own thanks and walked away. Suddenly he ran bark and gave me a big hug.
“Thanks again. No one even knew my mother didn’t 54 it.”
I ended my workday with a hug from a teenage boy who 55 stopped hugging teachers years ago.

Ausubel of Rockefeller University in New York, US. says the key renewable energy sources, including sun, wind and biofuels, would all require vast 1 of land if developed up to large scale production1 – unlike nuclear power. That land would be far better left alone2, he says. Renewables look attractive when they are quite 2 . But if we start producing renewable energy on a large scale, the fallout is going to be horrible. Instead, Ausubel argues 3 renewed development of nuclear.
Ausubel draws his conclusions by analysing the amount of energy renewables, natural gas and nuclear can produce in terms of power per square metre of land used3. Moreover, he claims that as renewable energy use increases, this measure of efficiency4 will 4 as the best land for wind, biofuels, and solar power gets used up.
Using biofuels to obtain the 5 amount of energy as a 1000 megawatt nuclear power plant would require 2500 square kilometres of farm 6 , Ausubel says. "We should be sparing land for nature5, not using it as pasture for cars and trucks," he adds.
Solar power is much more efficient than biofuel in terms of the area of land 7 , but it would still require 150 square kilometres of photovoltaic cells to 8 the energy production of the 1000 MW nuclear plant. In another example, he says meeting the 2005 US electricity demand via wind power alone would need 780,000 square kilometres, an area the size of Texas.
However, several experts are highly critical 9 Ausubel’s conclusions. John Turner of the US government’s National Renewable Energy Laboratory says that 10 the US got all of its power from solar energy, it would still need less than half the amount of land that has been paved over for highways. Further, it need not 11 additional land. The US could get a quarter of its energy just from covering rooftops of 12 buildings, he says.
According to Turner, the same "dual use" also applies to wind power6. "The footprint for wind7 is only 5% of the land that it 13 . Farmers can still farm the land that the turbines are on8. Turner says looking solely at land use is an oversimplification of the 14 . "I’m not sure I’d want to build one of these nuclear plants in Afghanistan9, but we could 15 put in wind and solar power," he adds.

The product, called Speed Alert, links real-time location data and speed obtained with the help of GPS(全球定位系统) to a database of posted speed limits stored in a driver’s PDA or programmable mobile phone.The setup of the product does not need to be hooked(钩住) up to a car’s speedometer.In fact, it is entirely portable.It will also work with newer phones and PDAs that have built-in GPS receivers.If a driver exceeds(超过) the speed limit, the speed is shown and an alert sounds.
Michael Paine, an Australian vehicle design engineer and traffic safety consultant, was hired to analyze the product.He told Live Science that his colleagues in the road safety field are “very enthusiastic” about what they’re now calling “intelligent speed alert.” Other research, according to Paine, shows that 40 percent of all traffic deaths involve speeding.There is also a potentially future use: “Since the system is so portable, it would be easy to make it a requirement for teenage drivers to always use a speed alert device when driving,” Paine said.“The system even has the function to record speeding violations(违背), so parents can monitor their teenage drivers.”
The product will soon go on sale in Sydney.
41.What’s the purpose of the new product_______.
A.To inform us of the new car system. B.To introduce some improvement in cars.
C.To limit certain drivers to safe driving. D.To popularize the built-in car system.
42.Lead-footed drivers refer to the ones .
A.who drive too carelessly B.that drive extremely fast
C.who are partly disabled D.that drive too slowly
43.The second paragraph mainly talks about .
A.the project of the built-in product B.why the system becomes popular
C.the functions of GPS in cars D.how the product is programmed
44.Which of the following is true of Speed Alert according to Michael Paine?
A.Most of the traffic deaths can be avoided.
B.Speeding violations can be easily found out.
C.The system will excite some teenage drivers.
D.The product will not be available for adults.
Many teachers are opposed to it.They don’t mind being evaluated.But they are upset because the results are then being posted on the Internet and accessible to millions of Internet users.On the website www. spickmich.de during the past four months students have posted evaluations of 100,000 teachers.
The teachers are graded on categories such as “motivated”, “good instruction,” “easy examinations”, or even “sexy.” Many teachers think that their privacy has been violated.
The creators of the website say that the students are only being offered the chance to provide teachers with some feedback about their classroom instruction.Bernd Dicks, who founded the website with three friends, says that the students are largely quite satisfied with their teachers.On a grading scale of one to six, the teachers’ average grade is 2.7 and it has been improving lately.He often says the impression is that students are bullying(欺负) their teachers.But there is also bullying of the students by teachers.
“Teachers must also learn to live with criticism,” he added.But still, the website is not totally immune from manipulation(操纵), as one teacher near the northern city of Hanover recently proved.He registered himself on the website as a student and then rated his own teaching colleagues highly.Within a few days, seven of his colleagues were listed in the top 10 rankings of Germany’s best teachers.
45. Many teachers are opposed to the website because .
A.their privacy has been violated B.they are afraid of being assessed
C.their evaluations are unfair D.the results are not satisfying
46.The founders of the website intended to .
A.get the students to know their teachers better
B.conduct a survey on teachers’ performances
C.help the teachers to improve their teaching
D.change the teachers’ ways of giving instructions
47.From what the teacher in Hanover did, we can infer .
A.he intended to help his colleagues
B.there was some disadvantage of the website
C.his colleagues were more popular than him
D.he wanted to know how he was evaluated
48.Which of the following can be the best title of the passage?
A.Teachers get graded by pupils B.Teachers are angry with website
C.Teachers need self-assessment D.New invention in assessing teachers
About 2,000 years ago, the world population was probably about 250 million. It reached a billion in 1850. By 1930 the population was two billion. It is now three and a half billion. It is expected to double by the year 2,000. If the population continues to grow at the same rate, there will be 25 billion in the world a hundred years from now.
Man has been using the earth’s resources more and more rapidly over the past years. Some of them are almost used up. Now many people believe that man’s greatest problem is how to control the growth of the population. The material supplies in the world will be far from enough to support the human population, in time to come, if the present rate of increase continues. Already there is overcrowding in many cities and starvation in some countries. Should man’s population keep on growing so rapidly as before? Many people believe that human survival in the future depends on the answer to this question.
59. The rapid increase in population is considered to be __________.
A. the increase of resources B. population pollution
C. the development of mankind D. the present rate
60. The world population will be _________ by the year 2,000.
A. 7 billion B. 250 million C. 25 billion D. 3.5 billion
61. If the present rate of increase continue, ________________.
A. the world is going to end
B. the earth won’t be able to support the growing population in the future
C. pollution has nothing to do with the rapidly increasing population
D. there would be four billion in the world a hundred years from now
62. Which of the following is WRONG according to the passage?
A. In 1850 the world population reached a billion.
B. Man must fight a battle against population pollution.
C. The world’s population is increasing with years.
D. All of the earth’s resources are gone now.
