       Unlike modern animal scientists, dinosam scientists cannot sit on a hillside and use telescopes to
watch dinosaurs in order to know how they lived and whether they were good parents Instead, they
have to search hard for information from dinosaurs’fossils（恐龍化石）because dinosaurs died out
millions of years ago.
       It’s very difficult for the scientists to reach an agreement because different results can be got from
the same fossils, Many fossils of the same kind of dinosaurs have been dug out from one place. They
might have formed when an entire group of dinosaurs got stuct（陷入）all st once. Or they might have
been the result of dinosaurs getting stuck one after another over a course of a few centuries. Thys we
can say that dinosaurs might have in the first case lived in big groups and in the second lived alone.
      Though there are two different results, dinosaur scientists now generally agree that at least some kinds
of dinosaurs lived in big groups. “That’s pretty much settled at this point.” Says Paul Sereno, A kind of
dinosaurs called Sauropods left behind tracks in the western United States that appear to run north and
south,suggesting that they even moved long distances together.
      As to whether dinosaurs cared for their young, dinosaur scientists have turned to the closest living
relativers of dinosaurs―birds and crocodiles―for possible models. Birds give a lot of care to their young,
while crocoeiles just help their young to the water, The discovered fossils of dinosaurs sitting on their gees
and staying with their  young  suggest the parents were taking care of their babies, but we still cannot say
that all dinosaurs did the same.
       There is still a long way to go before the above questions could be answered. Dinosaur scientists will
have to find more proof to reach an agreement.
1. Dinosaur scientists can get information directly by _____.
A. studying dinosaur fossils
B. examining modern animals
C. watching dinosaurs
D. using teleeopes
2. What is pretty much settled according to Paul Sereno?
A. Half of the dinosaurs lived alone.
B. Most dinosaurs moved long distances.
C. Many dinosaurs settled in the north.
D. Some dinosaurs lived in big groups.
3. Dinosaur scientists can probably know whether dinosaurs were good parents by _____.
A. watching many kinds of animals
B.  studying dinosaurs’living relatives
C. following the tracks left behind
D. working on dug-out dinosaur eggs
4.Which of the following is true according to the paragraph?
A. Birds hardly ay attention to their young.
B. Baby crocodiles can look after themselves well.
C. Some dinosaurs took care of their young.
D. Birds and crocodiles take good care of their young.

請認真閱讀下列短文，從短文后各題所給的A、B、C、D四個選項中，選出最佳選項，并在答題卡上將該項涂黑。
A
Around the age of 40, honest people may already admit to noticing changes in their mental abilities. This is the beginning of a gradual decline that in all too many of us will end with full-blown dementia(癡呆).
However, a few drugs that might do the job, known as “cognitive enhancement(認知增強)”, are already on the market, and a few dozen others are on the way. Perhaps the best-known is modafinil. Licensed to treat narcolepsy, the condition that causes people to suddenly fall asleep, it has notable effects in healthy people too. Modafinil can keep a person awake and his or her attention fixed for 90 hours straight, with none of anxiety, nervousness and bad concentration. In fact, with the help of modafinil, people who can hardly go to sleep can perform even better than their well-rested, un-medicated(未服藥的) selves.
It’s an open secret that many, perhaps most, prescriptions for modafinil are written not for people who suffer from narcolepsy, but for those who simply want to stay awake. Similarly, many people are using Ritalin not because they suffer from attention problem or any other disorder, but because they want superior concentration during exams or heavy-duty activities.
Some drugs have also been specially designed to improve memory. Many of these seem to work, and without any major side effects. So why aren’t we all on cognitive enhancers already?
“We need to be careful what we wish for,” says Daniele Piomelli at the University of California at Irvine. Repairing and improving memory may have unwanted effects, he warns. “Eventually we may end up remembering things we don’t want to.”
56. According to the message, we can learn that originally modafinil is a drug designed for _____.
A. for both healthy and unhealthy people
B. the treatment of dementia
C. people who can hardly go to sleep
D. those suffering from falling asleep suddenly
57. The passage mainly talks about _____.
A. dementia—a threat to the old people                     B. modafinil—a nice drug for dementia
C. relevant drugs to a better brain                      D. cognitive enhancement
58. The underlined sentences in paragraph two wants to tell us that _____.
A. without modafinil people suffering from sleep problems cannot rest well
B. people lacking sleep can work better than they are in a healthy state if taking modafinil
C. modafinil has greater effects on healthy people if they take it
D. with modafinil people suffering from narcolepsy can fall asleep easily
59. What’s the writer’s attitude to the drugs mentioned in the passage?
A. Positive.    B. Negative.    C. Objective(客觀的).   D. Doubtful.

閱讀理解
     The UN Environment Programme says that rising temperatures could mean the end for some migrating animals.
     Migrating or mobile animals move through several environments as they travel away from the cold of
winter to warmer areas. Birds may fly from one part of the world to another, perhaps stopping at feeding
grounds on the way. Whales and turtles (海龜) cover vast areas of ocean. The report says that changes in any one of the places which these animals use can cause serious harm. "Obviously these animals have
developed their travelling patterns over thousands of years. But climate change is almost certain to be
extreme over the next 25 to 50 years and it is extremely unlikely that these animals can change their habits
fast enough," said the report author Dr Robert Hepworth.
     Hardest hit by rising temperatures are turtles. Scientists have found that at higher temperatures, turtles
produce far more female eggs than male ones. In parts of Malaysia, turtle birthing sites are producing only
females, the report says. It also provides evidence that some turtles are more likely to develop cancer as
the waters get warmer.
    With birds, the main problem is climate-related damage to important areas at either end of the travels or at resting places along the way. About one-fifth of migrating birds are now in danger because of
climate-related changes including rising sea levels, land loss and more violent storms, the report concludes.
Other animals picked out as particularly in danger include:
    the North Atlantic Right Whale, whose main food (tiny shrimp) is disturbed by the change in ocean
flows and
    the White-Nose Dolphin, which is out-competed by other kinds of dolphins in warmer waters.
The report is not all bad news. Even with major climatic changes, protecting the environment can still help mobile animals to recover. "We need governments to start taking action at the national and international
lever. “The clock is running.” said Dr Hepworth. And some animals are already adapting, with the report
mentioning whales that are changing their feeding behaviour, finding new feeding grounds and new foods to eat.

1. What is the main topic of the text?
A. The effect of climate change on migrating animals.
B. How animals are adapting to changes in temperature.
C. The actions required to save migrating animals.
D. The need for government policies to prevent global warming.

2. By saying "the clock is running" in the last paragraph, Dr Hepworth means that “_______”.

A. it may be too late to save some animals
B. it is time to start protecting the animals
C. there is not much time to solve the problem
D. it takes time to complete the actions

3. According to the report, how will global warming affect turtles in the future?

A. They will only produce female babies.
B. Their food supply will gradually disappear.
C. Some will suffer from higher rates of cancer.
D. They will be in greater danger because of more violent storms.

4. Which of the following is mentioned as a consequence of rising temperatures?

A. More storms will affect the ability of whales to find their feeding grounds.
B. 20 percent of all birds are likely to die out because of land loss.
C. Migrating animals are likely to start adapting to the changes more quickly.
D. Warmer oceans will increase the competition between different kinds of dolphins.

5. What can be inferred (推斷) about turtles from the text?

A. They are the only animals besides humans that suffer from cancer.
B. They have traditionally lived longer than other ocean-based animals.
C. Those born nearer a hotter area are more likely to be female.
D. Most kinds of turtles are likely to die out within 50 years.
