In the dark night of the desert,a group of U.S.Air Force scientists is testing a new device for a missile to target.Designed to seek out the heat of an enemy aircraft engine,it is now going through its paces by tracing the movement of a flashlight waving thirty feet away in the darkness.A hundred yards away,unseen by the man,a rattlesnake sliding between the stones senses a patch of warmth. Although the snake's mechanism is small enough to be packed into a head the size of a nut,it can detect a change in temperature of one-thousandth of a degree.With a sound the snake closes in and strikes for the kill.
Whenever we look in the animal world we find the same story.Almost anything that man can do,nature has already done better. So,it is for the purpose of learning from nature that a new science called bionics has grown up.Its aim is to find out how animal's instruments work so that man can copy them for his own purpose.
Imagine being able to know a friend several miles off by his smell. Male silk moths can do this. Their antennae are so sensitive to the chemical odor of female moths that they can detect their presence by picking up only one molecule of the chemical.Even with their most sensitive instruments, human cannot approach this perfection.
Studying beetle's eyes has already paid off. A group of scientists in Germany found that a beetle can accurately measure with its eyes the speed of moving background.After finding out how a beetle accomplishes this scientists built a machine that operated on the same principle.This instrument is able to determine the ground speed of moving aircraft with a high degree of accuracy.

Which of the following can be used to replace the word"accomplishes"?
A:Succeeds in.
B:Completes.
C:Does.
D:Finishes.

His immature behavior was not so interesting.

A:naive
B:foolish
C:childish
D:silly

flowering,the appearance of leaves and the first frog calls of the spring一all around the world.But ecologists
can't be everywhere so they're turning to non-scientists,sometimes called citizen scientists,for help.
Climate scientists are not present everywhere.Because there are so many places in the world and not
enough scientists to observe all of them,they're asking for your help in observing signs of climate change
across the world.The citizen scientist movement encourages ordinary people to observe a very specific

research interest一birds,trees,flowers budding,etc.and send their observations to a giant database to be
observed by professional scientists.This helps a small number of scientists track a large amount of data that they
would never be able to gather on their own.Much like citizen journalists helping large publications cover a
hyper-local beat,citizen scientists are ready for the conditions where they live in.All that's needed to become
one is a few minutes each day or each week to gather data and send them in.
A group of scientists and educators launched an organization last year called the National Phenology
Network."Phenology"is what scientists call the study of the timing of events in nature.
One of the group's first efforts relies on scientists and non-scientists alike to collect data about plant
flowering and leafing eveiy year.The program,called Project BudBurst,collects life cycle data on a variety of
common plants from across the United States.People participating in the project一which is open to every-
one一record their observations on the Project BudBurst website.
"People don't have to be plant experts一they just have to look around and see what's in their neighbor-
hood,"says Jennifer Schwartz,an education consultant with the project."As we collect these data,we'll be
able to make an estimate of how plants and communities of plants and animals will respond as the climate
changes."

What are citizen scientists asked to do?
A:To develop a specific research interest and become professional scientists.
B:To send their research observations to a professional database.
C:To increase their knowledge about climate change.
D:To keep a record of their research observations.

Einstein's Theory of Relativity was so pofound that only a few scientists could understand it.

A:deep
