a world filled with smart robots, which will be helping you to take care of your children, or your elderly
parents in your home. You"ll live much longer thanks to the medicine made by genetic (基因的) science.
And mankind may be going farther in space than ever before-you will be living on the moon or Mars.
How should we view the changes that wait for us in the future? Should we be optimistic about the years
ahead, or worried about what the future holds? Some scientists and experts are having a discussion about how technology, science and society will develop in the future.
"I"m looking forward to the day when more technology will come to my life," says John Searle, a
professor at the University of California Berkeley Philosophy, "because I think further research in such
areas as genetics, physics, chemistry and medicine will help us to overcome poverty, improve health,
and make life longer."
Hugh Herr, at MIT"s Biomechatronics Group, considers very powerful weapons as concern over
the future. Another is the growing role of technology in our lives."Machines taking over what humans
do is not a good thing," Herr says.
That is a similar concern shared by Daniela Cerqui, a social and cultural scientist. "I am afraid
that the long-term future we are building will have no space left for human beings," says Cerqui. "The
main values of our society are related to information that must progress as quickly as possible, and
computers are much better than humans in these tasks ."
B. how people will live in a modern society
C. what life would be like in the future
D. what computers will bring to our society
B. Optimistic.
C. Uncertain.
D. Disappointed.
B. machines taking over what humans do
C. the technology of weapons
D. the health problem of humans
B. Great changes will take place in the future
C. The relationship between technology and humans

live perfectly well. But some fish put us to shame. They can get by without stomachs.
One such fish is the stout longtom. The group it belongs to carries a more appropriate name: the
needlefish. All needlefish lack stomachs. Their ancestors had them, but later they were lost.
The stout longtom can reach 1.3 meters in length, and lives near the sea surface. Like all needlefish, it
can jump out of the water to escape its enemies. Tropical fishermen are sometimes injured by needlefish.
In 1977, a 10-year-old Hawaiian boy was killed when a needlefish jumped through his brain. The
longtom eats smaller fish. It teeth are not good at cutting fish into pieces, so it swallows fish whole.
Ryan Day from Australia and his colleagues wanted to know how the longtom digests its meaty meals without a stomach, so they ran some chemical tests about the fish.
Day"s results show that the longtom can consume food without the help of a stomach. It uses a special material called trypsin that can break down proteins without acid - although the approach is less efficient
than using a stomach.
Because it"s a meat-eating animal, the longtom gets a lot of protein in its food, so it can afford this
slightly less efficient system for absorbing it. Two plant-eating fish that Day studies actually had higher
levels of trypsin in their body, as their food was low in protein.
Day thinks that the longtom and its stomachless relatives might actually have arrived at an
energy-saving solution. He says that although the stomach is critical to many kinds of animal, the organ is
"a fairly expensive organ to run". This perhaps explains why some animals have got rid of theirs.
B. Fight.
C. Hunt.
D. Live.
B. digests the smaller fish in its body
C. can jump so high to escape its enemies
D. uses acid to break down the protein
B. Acid
C. The stomach.
D. Protein in its body.
B. the longtom often waste energy
C. the longtom"s high-protein food helps its unique way of consuming food.
D. meat -eating fish have higher levels of trypsin in their bodies than plant-eating fish
resting time.
However, another study shows that sitting in front of computer or TV screens for long hours is not the
only reason for myopia (近视). An Australian research team studied young children in Sydney and
Singapore to find the reasons for myopia.
The research team found that the prevalence (流行) of myopia among children in Sydney was lower
than children in Singapore, even though they spent more time in front of computer and TV screens. The
major finding is that children in Sydney spend longer hours on outdoor activities than those in Singapore.
Indoor and outdoor sports activities both make the eyes focus on more distant objects, which prevents
the eyes from changing shape. But outdoor activities may better help avoid myopia than indoor sports
activities.
Jane Gwiazda, who does research in sight problems, says: "Natural light is good for eye growth. And
extra vitamin D from the sun might contribute to eye growth."
Many doctors suggest that every child get its first eye test done when he/she is about two and half
years old, and even if his/her sight seems perfect.
It is necessary for myopic children to wear glasses to prevent headaches, trouble reading or injuries. It
is also important that schools invite doctors to test their students" eyes.
If that is not possible, school teachers should at least encourage parents and children to have regular
eye examinations and wear glasses. And parents should remember not only to limit the total screen time
for their children, but also to encourage them to spend time outdoors.
B. To find the ways to treat myopia.
C. To prove the bad effects of myopia.
D. To prove the prevalence of myopia.
B. Because Sydney children have more eye resting time.
C. Because Sydney children use computers less.
D. Because Sydney children do more outdoor sports.
B. Singapore children do few exercises.
C. Outdoor activities do more good to eyes.
D. Room light does harm to children"s eyes.
B. Doing outdoor activities with no glasses is good for myopia children.
C. Focusing on distant objects can help the eyes keep their original shape.
D. Children should limit their time in the sun in order to protect their eyes.

| We know that many animals do not stay in one place. Bird, fish and other animals move from one place to another at a certain time. They move for different reasons: most of them move to find food more easily, but others move to get away from places that are too crowded. When cold weather comes, many birds move to warmer places to find food. Some fishes give birth in warm water and move to cold water to feed. The most famous migration (迁移) is probably the migration of the fish, which is called "salmon". This fish is born in fresh water but it travels many miles to salt water. There it spends its life. When it is old, it returns to its birthplace in fresh water. Then it gives birth and dies there. In northern Europe, there is a kind of mouse. They leave their mountain homes when they become too crowded. They move down to the low land. Sometimes they move all the way to the seaside, and many of them are killed when they fall into the sea. Recently, scientists have studied the migration of a kind of lobster (龙虾). Every year, when the season of bad weather arrives, the lobsters get into a long line and start to walk across the floor of the ocean. Nobody knows why they do this, and nobody knows where they go. So, sometimes we know why humans and animals move from one place to another, but at other times we don"t. Maybe living things just like to travel. | |||

| Robots are being used for the first time in hospitals. "Robot-nurses" perform a variety of tasks such as delivering medicine, food and laboratory samples to sickrooms and taking away waste. Patients aren"t treated by robots, as this is still done by medical staff. The idea is to employ robots to transport supplies between departments. "Nurses often have to break off from what they are doing to gather supplies," says Peter Seiff, who makes the robots called TUGs. Research shows any interruption in medical work can lead to errors-a nurse may forget whether she has given medicine and may give a patient double the dose (剂量) or none at all. The robots vary in size according to what job they perform, but normally take the shape of a metal box on wheels, with a box on the side containing their software. After being programmed, the robots are able to find their way around a hospital unassisted. They also contain scanning technology to create electronic pictures or a "memory" of routes on their hard drives to help them go through passages, doors and other obstacles. Each robot is also monitored at the producer"s headquarters (总部) in case it runs into any difficulties. Trials show TUGs reduce the time it takes for a patient to receive medicine, and stop drugs from going missing. A study at the University of Maryland Medical Centre in the U.S. found that when three TUGs were used over the course of a year, the average length of time from the drugstore receiving a prescription to the patient receiving it dropped from 74 minutes to 30 minutes and saved nurses 6,123 hours finding medicines. It also cut the number of medicines that went missing to zero. "The biggest complaints we receive from patients is that the nurses don"t spend enough time with them. Anything that frees nurses is a boon," says Katherine Mulligan, director of nursing at the hospital, "The TUGs allow nurses to spend more time focusing on patient care. Nurse satisfaction has improved." | |||
| 1. Which of the following activities are robot-nurses NOT programmed to deal with? | |||
| A. Transporting supplies. B. Taking away waste. C. Taking care of patients. D. Creating electronic pictures. | |||
| 2. The underline word "boon" in the last paragraph probably means . | |||
| A. benefit B. dream C. habit D. complaint | |||
| 3. Which of the following is TRUE according to the passage? | |||
| A. Robots can help nurses save a lot of time. B. All robots have the same size. C. Robots are unable to find their way by themselves. D. Robots cannot get help if they run into difficulties. | |||
| 4. What is the attitude of the author towards robot-nurses? | |||
| A. Neutral. B. Positive. C. Negative. D. Unknown. |
