Captain Cook Arrow Legend
It was a great legend while it lasted, but DNA testing has 1 ended a two-century-old story of the Hawaiian arrow carved from the bone of British explorer Captain James Cook 2 died in the Sandwich Islands1 in 1179.
“There is 3 Cook2 in the Australian Museum,” museum collection manager Jude Philip said not long ago in announcing the DNA evidence that the arrow was not made of Cook’s bone. But that will not stop the museum from continuing to display the arrow in its 4 , “Uncovered: Treasures of the Australian Museum,3” which 5 include a feather cape presented to Cook by Hawaiian King Kalani’opu’u in 1778.
Cook was one of Britain’s great explorers and is credited with 6 the “Great South Land,” 7 Australia, in 1770. He was clubbed to death in the Sandwich Islands, now Hawaii.
The legend of Cook’s arrow began in 1824 8 Hawaiian King Kamehamcha on his deathbed gave the arrow to William Adams, a London surgeon and relative of Cook’s wife, saying it was made of Cook’s bone after the fatal 9 with islanders.
In the 1890s the arrow was given to the Australian Museum and the legend continued 10 it came face-to-face with science.
DNA testing by laboratories in Australia and New Zealand revealed the arrow was not made of Cook’s bone but was more 11 made of animal bone, said Philp.
However, Cook’s fans 12 to give up hope that one Cook legend will prove true and that part of his remains will still be uncovered, as they say there is evidence not all of Cook’s body was 13 at sea in 1779. “On this occasion technology has won,4” said Cliff Thornton, president of the Captain Cook Society，in a 14 from
Britain. “But I am 15 that one of these days … one of the Cook legends will prove to be true and it will happen one day.”

Affectionate Androids
Computers are now powerful enough to allow the age of humanoid robots to dawn1. And it won’t be long before we will see realistic cyber companions, complete with skin, dexterity, and intelligence. They will be programmed to tend to your every need.
Will we ever want to marry robots? Artificial intelligence researcher David Levy has published a book claiming human-robot relationships will become popular in the next few decades. ____1____Will humans really be able to form deep emotional attachments to machines? It will, in fact, be relatively easy to form these strong attachments because the human mind loves to anthropomorphize: to give human attributes to other creatures—even objects.
For example, researchers in San Diegorecently put a small humanoid robot in with a toddler playgroup for several months. ____2____ The children ended up treating it as a fellow toddler. When it lay down because its batteries were flat，the kids even covered it with a blanket.
In a few decades, when humanoid robots with plastic skin look and feel very real, will people want to form relationships with them? What if the bots could hold a conversation? And be programmed to be the perfect companions—soul mates, even? ____3____ And like those toddlers in the experiment, they will be very accepting of them.
The next question, then, is whether there is anything wrong with having an emotional relationship with a machine. Even today there are people who form deep attachments to their pets and use them as substitutes for friends or even children. Few consider that unethical.
____4____ For those who always seem to end up marrying the wrong man or woman, a robotic Mr. or Ms. Right could be mighty tempting. As the father of artificial intelligence, Marvin Minsky, put it when asked about the ethics of lonely older people forming close relationships with robots: “If a robot had all the virtues of a person and was smarter and more understanding, why would the elderly bother talking to other grumpy old people?”
A robot could be programmed to be as dumb or smart, as independent or subservient, as an owner desired. And that’s the big disadvantage. Having the perfect robot partner will damage the ability to form equally deep human-human relationships. People will always seem imperfect in comparison. When you’re behaving badly, a good friend will tell you. ____5____People in relationships have to learn to adapt to each other: to enjoy their common interests and to deal with their differences. It makes us richer, stronger, and wiser. A robot companion will be perfect at the start. However, there will be nothing to move the relationship to grow to greater heights.

The First Four Minutes
You may have noticed that the average person does not give his undivided attention to someone he has just met. ___2___ If anyone has ever done this to you, you probably did not like him very much.
When we are introduced to new people, the author suggests, we should try to appear friendly and self-confident. In general, he says, “People like people who like themselves1. ”
On the other hand, we should not make the other person think we are too sure of ourselves. It is important to appear interested and sympathetic，realizing that the other person has his own needs， fears, and hopes.
Hearing such advice, one might say, "But I"m not a friendly, self-confident person. That"s not my nature. It would be dishonest for me to act that way. ”
___3___We can become accustomed to any changes we choose to make in our personality. “It is like getting used to a new car. It may be unfamiliar at first, but it goes much better than the old one. ”
But isn"t it dishonest to give the appearance of friendly self-confidence when we don"t actually feel that way? Perhaps, but according to Dr. Zunin, "total honesty" is not always good for social relationships2 ’ especially during the first few minutes of contact. There is a time for everything, and a certain amount of play-acting may be best for the first few minutes of contact with a stranger3. That is not the time to complain about one"s health or to mention faults one finds in other people. It is not the time to tell the whole truth about one"s opinions and impressions.
___4___For a husband and wife or a parent and child, problems often arise during their first four minutes together after they have been apart. Dr. Zunin suggests that these first few minutes together be treated with care. If there are unpleasant matters to be discussed, they should be dealt with later.
The author says that interpersonal relations should be taught as a required course5 in everyschool, along with reading, writing, and mathematics. ___5___That is at least as important as how much we know.
Undivided/ ʌndɪ"vaɪdɪd / adj．不分散的，专一的
accustomed / ə"kʌstəmd / adj．惯常的
personality / pɜːsə"nælɪtɪ / n．个性，人格
1.People like people who like themselves.人们喜欢那些有自信心的人。这里的who like themselves不作“喜欢自己”解，根据上下文，可以解释为“有自信的人”。
A In reply, Dr. Zunin would claim that a little practice can help us feel comfortable about changing our social habits.
B Much of what has been said about strangers also applies to4 relationships with family members and friends.
C In his opinion, success in life depends mainly on how we get along with other people.
D Every time you meet someone in a social situation, give him your undivided attention for four minutes.
E He keeps looking over the other person"s shoulder, as if hoping to find someone more interesting in another part of the room.
F He is eager to make friends with everyone.
