The world's oceans have warmed 50 percent faster over the last 40 years than previously thought due to climate change, Australian and US climate researchers reported on Wednesday. Higher ocean temperatures expand the volume of water, contributing to a rise in sea levels that is submerging small island nations and threatening to great damage in low-lying, densely-populated delta regions around the globe.
The study, published in the British journal Nature, adds to a growing scientific chorus of warnings about the pace and consequences of rising oceans. It also serves as a corrective to a massive report issued last year by the Nobel-winning UN Intergovernmental Panel on Climate Change(IPCC), according to the authors.
Rising sea levels are driven by two things: the thermal(熱)expansion of sea water, and additional water from melting sources of ice. Both processes are caused by global warming. The ice sheet that sits at the top of Greenland, for example, contains enough water to raise world ocean levels by seven metres(23 feet), which would bury sea-level cities from Dhaka to Shanghai.
Trying to figure out how much each of these factors contributes to rising sea levels is critically important to understanding climate change, and forecasting future temperature rises, scientists say. But up to now, there has been a confusing gap between the projections of computer-based climate models, and the observations of scientists gathering data from the oceans.
The new study, led by Catia Domingues of the Centre for Australian Weather and Climate Research, is the first to reconcile(與…一致)the models with observed data. Using new techniques to assess ocean temperatures to a depth of 700 metres(2,300 feet)from 1961 to 2003, it shows that thermal warming contributed to a 0.53 millimetre-per-year rise in sea levels rather than the 0.32 mm rise reported by the IPCC.
64. What happens when the ocean's temperature rises?
A. It causes sea levels to rise.
B. It causes sea levels to remain constant.
C. It causes sea levels to decrease.
D. It causes sea level to change.
65. Which of the followings would be buried by the rising sea?
A. Small island nations.
B. All coastal cities around the world.
C. People who enjoy holiday on the beach.
D. Low-lying regions.
66. The new study in this passage _____________.
A. shows that thermal warming contributed to a 0.32 millimeter-per-year rise in sea levels.
B. did not reveal anything that scientists hadn't already known.
C. used new techniques to assess ocean temperatures.
D. shows that models contradict the observed data.
67. What was the main finding of the study?
A. Nothing enough is being done about global warming.
B. That ocean waters have warmed faster than scientists had previously thought.
C. That the warming of the world's oceans is not a threat.
D. A massive report issued last year by IPCC was wrong.

The ocean contains many strange and surprising creatures. One such creature is the puffer fish. This very strange fish is probably the most poisonous creature in the ocean. The poison that this fish produces is 275 times more poisonous than the chemical which is usually used to kill rats.
The puffer fish gets its name from the way the fish protects itself from enemies. Whenever it is attacked, the fish blows up its body to three times bigger than its normal size!
Another strange thing about this fish is the fact that it can swim like other fish. Because it does not have bones like other fish, the puffer fish can only move slowly through the water as it is carried by waves.
The puffer fish also has funny teeth. These teeth stick out of the fish’s mouth and are used by the fish to open the shells of the creatures that live on the ocean floor.
This strange, ugly, and very poisonous fish is actually a very expensive kind of food in Japan. The Japanese call this fish “fugu”, and people have been known to pay $150 per person to eat a fugu meal (usually eight servings)!
Very brave people want to eat the most poisonous part of the fugu fish on purpose. They think that this part of the fish tastes the best! Strict laws have been passed to control restaurants which serve fugu; however, quite a few people have still died from eating fugu.Almost 200 people have died over the past 25 years.
When people eat fugu poison, they do not die on the spot. First, they feel a strange tickle on their lips and in their mouth. Then they can not feel anything with their fingers. Finally, they cannot move or speak. Death follows when they can no longer breathe. The poison may take only a few minutes or up to six hours to kill a person. There is no known cure for fugu poisoning.
小題1:According to the passage, the puffer fish       .

C.It gives off poison. D.It can swim swiftly.
小題3:The underlined expression “on the spot” in the last paragraph is closest in meaning to      .
A.now and then B.once in a while
C.then and thereD.sooner or later
小題4:Who is allowed to serve fugu according to the passage?
A.The Japanese government. B.Licensed restaurants.
C.Strict lawyers in Japan . D.Very brave people

In 1990 Peter Salovey Ph. D and John Mayer Ph. D coined the term Emotional Intelligence. Their research has opened many people’s eyes to the fact that EQ or emotional quotient holds the key to one’s happiness and well being, and helped us to realize that our emotional makeup can be so much more important than our mental, or what we refer to as IQ—intelligent quotient.
IQ is essential for learning and mental development and EQ is much more important for happiness and success. Some time ago a study done in the United States proved that doctors who were impatient and did not exhibit much care towards their patients were more likely to be sued (起訴) for malpractice(瀆職), whereas doctors who were caring and attentive to their patients were less likely to be sued even if they made a critical mistake. A woman wrote to newspaper recently telling about her brother. He was apparently a genius but did not get along with people, quit every job he started, and eventually became a taxi driver. These are just a few examples of people with high IQ but low EQ.
We have all known people who did not complete college, but who have become very successful in business. We call them street smart. We also know people who, on the whole, are positive, communicative, pleasant and supportive—these people enjoy a high level of EQ.
Many people wish to improve their EQ for the purpose of becoming happier, more successful, and at the same time more balanced, individuals. The remarkable thing about EQ is that it can always, at any age, be improved, unlike IQ, which remains more or less fixed in adult life.
Now psychologists start workshops focusing on showing people how to increase their EQ. This enables them to accomplish their dreams and desires, rid themselves of negative patterns and shows them that once they master their inner world, their outer world becomes much better.
47. In the second paragraph, the author gives us two examples to show that _____.
A. doctors in the United States are often involved in cases
B. working as a taxi driver in the United States requires high EQ
C. those with high IQ are often engaged in the low-rank work
D. those with low EQ have a harder time surviving in life
48. Which of the following can’t be used to describe the people with a high level of EQ?
A. They are positive, communicative, pleasant and supportive.
B. They are optimistic and untroubled by difficulties.
C. They are impatient and show little care towards others.
D. They may be very successful in business.
49. It can be inferred that predicting future successes, ______.
A. a person’s brainpower might actually matter less than a person’s character
B. a person’s IQ might be more important than a person’s EQ
C. IQ plays an important role as well as EQ
D. both IQ and EQ are the key points that should be considered
50. Which of following is NOT true according to the passage?
A. People with high IQ are likely to gain knowledge quickly.
B. At work EQ gets you hired easily and IQ gets you promoted.
C. Having a high IQ will help us in some ways but having a high EQ might help us even more.
D. People’s EQ could be raised much more than their IQ.

  A new study has found that it may be possible to train people to be more intelligent,increasing the brainpower they had at birth.
  Until now,it has been widely assumed that the kind of mental ability that allows us to solve new problems without having any relevant previous experience—what psychologists call fluid intelligence—is innate and cannot be taught(though people can raise their grades on tests of it by practicing).
  But in the new study,researchers describe a method for improving this skill,along with experiments to prove it works.
  The key, researchers found, was carefully structured training in working memory—the kind that allows memorization of a telephone number just long enough to dial it. This type of memory is closely related to fluid intelligence,so the researchers reasoned that improving it might lead to improvements in fluid intelligence.
  First they measured fluid intelligence of volunteers using standard tests. Then they trained each in a complicated memory task—the child’s card game,in which they had to recall a card they saw and heard. During the course, they needed to ignore irrelevant items,monitor ongoing performance,manage two tasks at the same time and connect related items to one another in space and time.
  The four groups experienced a half-hour of training daily for 8,12,17 and 19 days,respectively. To make sure they were not just improving their test-taking skills,the researchers compared them with control groups that took the tests without the training.
  The results, published Monday in The Proceedings of the National Academy of Sciences,were striking. Improvement in the trained groups was a lot greater. Moreover,the longer they trained, the higher their scores were. All performers,from the weakest to the strongest,showed significant improvement.
  “Our results show you can increase your intelligence with proper training.”said Dr Jaeggi, a co-author of the paper.“No one knows how long the gains will last after training stops,”he added,“and the experiment’s design did not allow the researchers to determine whether more training would continue to produce further gains.”
67.The researchers thought the key to improving the intelligence was ______________.
A.memorizing telephone numbers
B.improving working memory
C.training in concentration
D.recalling a card
68.The following aspects of the training help increase intelligence EXCEPT___________.
A.ignoring irrelevant items
B.monitoring ongoing performance
C.managing two tasks at the same time
D.using previous experience
69.When the experiment was conducted,the researchers______________.
A.trained the four groups for the same period of time
B.only made comparisons between the four groups
C.compared the four groups with control groups
D.trained the four groups together
70.By writing the article,the writer intends to ______________.
A.inform the readers of a new study
B.call on people to be trained to increase intelligence
C.prove one’s born brainpower can be improved
D.tell people the improved intelligence will last forever

“Help! Help! Help!” a resident screamed over the phone, “I am being eaten alive by mosquitoes!”
Recent rainfalls have produced an early hit of blood-seeking mosquitoes.Once flooded, eggs laid during the drought along water banks hatch(孵化)quickly, flying off to seek hosts such as people, birds, and other animals.
The flood mosquitoes are big and aggressive.They chase you down, drill into your skin and take your blood, causing pain and itchiness.“I have lost a pint of blood to those suckers,” a Spring Hill resident claimed.“Mosquitoes are killing my kids,” a Ridge Manor woman shouted.
Residents are urged to protect themselves when going out, especially during the hours of dusk and dawn.Long-sleeve shirts, long pants, socks and hats will help keep mosquitoes at bay.
Mosquito Control has already received hundreds of service requests this month.When calling in, residents need to provide their name, address, phone number and nature of the problem.Technicians will respond by investigating the problem and making proper treatment and notification to resident.
Mosquitoes grow in almost any kind or amount of water.Controlling mosquito larvae(幼蟲) is vital to mosquito control.Confined in their water habitat, larvae are treated and eliminated before they mature and “take to wing.” Field technicians check their areas searching for mosquitoes breeding in lakes, ponds, drainage ditches and they treat the water with a host of larvicides(殺幼蟲劑).
It is important to understand that mosquito control is much more than sending a spray truck (airplane or helicopter in other counties) to kill adult mosquitoes.Night-time spraying is actually the last defense after all the above procedures have been done, but there are still mosquitoes present in the area.
56.The author writes the first paragraph in order to _________.
A.make the public take action at once
B.a(chǎn)ttract readers to read the following contents
C.show that the people bothered by mosquitoes are helpless
D.criticize the government has done nothing
57.When do the eggs hatch according to the passage?
A.When the flood hits.     B.During the drought.
C.After the flood leaves.  D.When spring comes.

The Red Panda isn’t much bigger than an average size house cat. At first you may think it’s a bear because of its name. They’re actually a member of the raccoon(浣熊) family which you can tell if you look at their appearance. The Red Panda has a long bushy tail that is useful in two ways. It helps them stay balanced when they are high up in the trees and it keeps them warm in cold weather. Their fur is thick and reddish brown, which may be why they’re known as the fire fox.
The Red Panda can be found in forested mountains. They’re originally from the forested mountain in the Himalayas in India, Nepal and Southern China. Bamboo is the most important part of their diet. They only eat the young leaves and shoots (嫩芽) of a bamboo plant. Red Pandas have a very low metabolic(新陳代謝的) rate in order to deal with their low energy diet and cool environmental temperatures.
They’re very shy and gentle and don’t hang around the wild too much during the day. If they feel endangered, they’ll stand on their back legs and make a hissing(嘶嘶) sound. Red Pandas are good climbers and spend most of their time living mainly in trees. Their claws are very strong and help them hold onto the branches. They sleep in an unusual way by curling up tightly and wrapping their tails around their heads while sitting on a branch. Sometimes they’ll sleep with their head beneath their chest and behind their back feet. This is the same position as an American raccoon sleeps.
小題1:You can tell that the Red Panda is a member of the raccoon family from ____.
A.its nameB.its appearanceC.its dietD.its living place
小題2:Which of the following is TRUE according to the passage?
A.The Red Panda can only be found in India, Nepal and Southern China.
B.The Red Panda’s tail can help it stay balanced when it is high up in the trees.
C.The Red Panda eats the whole of the bamboo.
D.The Red Panda has high metabolic rate when the temperature is low.
小題3:What will Red Pandas do when they are in trouble?
A.They will hang around the wild during the day.
B.They will climb into the trees.
C.They will wrap their tails around their heads.
D.They will stand on their back legs and make a hissing sound.
