[单项选择]Is teaching important Well, of course it is. There was a time when the necessary knowledge could be taught to the young by family members. (25) But as societies became more complex and division of labor more common, it was impossible for family members to teach the information and skills young people needed to become useful members of the society. As the need for specialists appeared, the job of teaching came into being in our society, and teaching as a job has been of increasing importance over the past hundred years. Today, we have strict rules for teachers. We hope all children can attend schools. Many things tell us that teaching is indeed an "important" job. In recent years, there has been an increasing need for teachers to be "responsible". This means that the public expects teachers to succeed in teaching important information to the young. Teachers’ salaries today, while not much, certainly are much higher than they were in years past. These increases have come about be

[简答题] Open source’’s local heroes
Software: If the commercial sort does not speak your language, open-source software may well do so instead
Its popularity is growing around the world, but open-source software has particular appeal in developing countries. In China, South Korea, India, Brazil and other countries, governments are promoting the use of such software which, unlike the proprietary kind, allows users to inspect, modify and freely redistribute its underlying programming instructions. The open-source approach has a number of attractions. Adopting open-source software can reduce costs, allay security concerns and ensure there is no danger of becoming too dependent on a foreign supplier. But there is another benefit, too; because it can be freely modified, open-source software is also easier to translate, or localise, for use in a particular language. This involves translating the menus, dialogue boxes, help files, templates and message strings to

Archive Gallery: The Best of Bionics(仿生学)
Humans might be the most highly-evolved species on the planet,but most animals possess skills we can
only dream of having.Imagine how much electricity we could save if we could see in the dark the way cats
do. Imagine leaping from tree to tree like a monkey.Giraffes(长颈鹿),which are otherwise calm and good-
natured,sleep only 4.6 hours a day.
We realized a long,long time ago that nature provides the best blueprint(蓝图)for invention.We've
borrowed canals from beavers(河狸)and reflectors from cat's eyes.Although the words "bionics" became
popular only after the 1960s,history shows that nature has always provided ideas on solving everyday prob-
lems. Our archives(档案)don't go back to the time of Leonardo da Vinci and his bird-like flying machines,
but we can take you to the late 19th century,where we applied those same principles for building our first
practical airplanes.
To prepare for their flight at Kitty Hawk,the Wright brothers studied the movements of pigeons to figure
out how they stayed high up when they were heavier than air. Their success inspired scores of successors to
improve on the airplane by studying various aspects of nature,One of Orville Wright’、pupils caught and
stuffed seagulls to examine their wingspan.Meanwhile,two French inventors examined spinning sycamore(美
国梧桐)seeds in an effort to apply those same motions,reversed,to a helicopter.
Some examples are more obvious than others.The outside of the airplane designed by the Wright
brothers looks like a minimalistic(简单抽象艺术)structure. On the other hand , Barney Connett ' s fish
submarine(潜水艇)actually looks like a fish.
Some bio-inspired concepts have yet to be invented.In the 1960s,the US Army commissioned several
university professors to conduct research on the motor skills of animals in hope of applying those same abili-
ties to tanks. Tanks that run like horses or jump like grasshoppers(蚂昨)一sounds shocking,doesn't it?
But imagine how life would change if we could achieve that.
What does the writer want to tell in the passage?
A.Some animals possess unique skills.
B.Many inventions get ideas from nature.
C.People should protect nature.
D.Bionics is far from perfect.
