e group.In a beehive there live three kinds of bees:the queen bee，the male bees and the worker bees.The worker bees are born to be hard-working，flying from flower to flower collecting nectar（花蜜），which is made up mostly of sugar mixed with water.Bees draw this nectar into their honey bags where some sort of liquid in their bodies turns the nectar into honey.The newly made honey flows slowly from the bees’ underside and then is stored in small cells in the hive.When the weather turns cold，and there are no flowers for them to collect nectar，the stored honey will see them through the winter months.People who raise bees and depend on bees for a living are thought of as beekeepers.A bee-keeper usually keeps hundreds of hives，and removes honey from hives and keeps it in glass bottles or jars.Honey usually appears as a clear golden-colored liquid，but this lie
s in the sort of flowers from which bees have taken the nectar.66.The best title of this passage is_______.
A.The Social Habits of Bees B.Three Kinds of Bees
C.The Production of Honey D.Bee Keepers’ Work
67.Bees are regarded as social insects because they_______.
A.form themselves into a good organization
B.have learned something from human society
C.need beekeepers to arrange their jobs
D.are born to work hard
68.The color of honey in its final stage depends on the_______.
A.type of flowers which the nectar is taken from
B.amount of sugar the beekeeper gives the bees
C.season in which the nectar is collected
D.quantity of water the bees are able to drink
69.Worker bees are always busy collecting nectar in order to_______.
A.help beekeepers to earn money from honey
B.turn it into honey

Hydrogen is a colorless, smell-less gas that takes up 75 percent of the whole universe. Hydrogen is found on earth only in mixture with other elements such as oxygen, carbon and nitrogen. To use hydrogen, we must separate it from these other elements.
Hydrogen can be used in NASA’s space program as fuel for the spaceships, and in fuel cells that provide heat, electricity and drinking water for astronauts. Fuel cells are devices that directly change hydrogen into electricity. In the future, hydrogen could be used to fuel vehicles and aircraft and provide power for our homes and offices.
Hydrogen can be made from natural gas. An electrical current can also be used to separate water into its elements of oxygen and hydrogen. Some plants in the sea and bacteria（细菌） give off hydrogen through sunlight under certain conditions.
Hydrogen as a fuel is high in energy. Yet a machine that burns pure hydrogen produces almost zero pollution. NASA has used liquid hydrogen since the 1970s to drive rockets and spacecraft into orbit. Hydrogen fuel cells power the spacecraft’s electrical systems, producing clean by-product-pure water, which the crew drinks.
56. We can get hydrogen from the following EXCEPT ______ according to the passage.
A. natural gas B. water C. creature in the sea D. bacteria
57. Why could the hydrogen be used widely in the future?
A. Because it is of high quality.
B. Because it has no pollution.
C. Because it is easy to get it from all kinds of ways.
D. Because there are much hydrogen existing in the universe.
58. The passage mainly tells us ________.
A. the usage of a new energy source B. the future energy sources
C. a new energy source －hydrogen D. how to get the energy source
C.

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.
