A man once said how useless it was to put advertisements in the newspapers. “Last week,” said he, “my umbrella was stolen from a London church. As it was a present, I spent twice its worth in advertising ,but didn’t get it back ”
“How did you write your advertisement ?”asked one of the listeners ,a merchant .
“Here it is,” said the man ,taking out of his pocket a slip cut from a newspaper. The other man took it and read, “Lost from the City Church last Sunday evening a black silk umbrella .The gentleman who finds it will receive ten shillings on leaving it at No 10 Broad Street .”
“Now ,”said the merchant, “I often advertise ,and find that it pays me well .But by the way in which an advertisement is expressed is of extreme importance .let us try your umbrella again ,and if it fails ,I will buy you a new one. ”
The merchant then took a slip of paper out of his pocket and wrote :“If the man who was seen to take an umbrella from the City Church last Sunday evening doesn’t wish to get into trouble, he will return the umbrella to No. 10 Broad Street .He is well known .”
This appeared in the paper ,and on the following morning ,the man was astonished when he opened the front door. In the doorway lay at least twelve umbrellas of all sizes and colors that had been thrown in and his own was among the number. Many of them had notes fastened to them saying that they had been taken by mistake, and begging the loser not to say anything about the matter

Everywhere man is altering the balance of nature．He is facilitating the spread of plants and animals into new regions, sometimes deliberately, sometimes unconsciously．He is covering huge areas with new kinds of plants, or with houses, factories, slag-heaps and other products of his civilization．He exterminates some species on a large scale, but favours the multiplication of others．In brief, he has done more in five thousand years to alter the biological aspect of the planet than has nature in five million．
Many of these changes which he has brought about have had unforeseen consequences．Who would have thought that the throwing away of a piece of Canadian waterweed would have caused half the waterways of Britain to be blocked for a decade, or that the provision of pot cacti for lonely settlers’ wives would have led to Eastern Australian being overrun with forests of Prickly Pear? Who would have prophesied that the cutting down of forests on the Adriatic coasts, or in parts of Central Africa, could have reduced the land to a semidesert, with the very soil washed away from the bare rock? Who would have thought that improved communications would have changed history by the spreading of disease-sleeping sickness into East Africa, measles into Oceania, very possibly malaria into ancient Greece?
These are spectacular examples; but examples on a smaller scale are everywhere to be found．We make a nature sanctuary for rare birds, prescribing absolute security for all species; and we may find that some common and hardy kind of bird multiplies beyond measure and ousts the rare kinds in which we were particularly interested．We see, owing to some little change brought about by civilization, the starling spread over the English country-side in hordes．We improve the yielding capacities of our cattle; and find that now they exhaust the pastures which sufficed for less exigent stock．
The following examples except ________ reflect man altering the balance of nature．

A．man is covering huge areas with new kinds of plants

B．man is facilitating the spread of animals into new regions．

C．man is killing some species on a large scale

D．man is getting to know the importance of keeping the balance of nature．

What had a piece of Canadian waterweed cause?

A．Eastern Australian was overrun with forests．

B．Half the waterways of Britain blocked for a decade．

C．In parts of central Africa, the land reduced to a semidesert．

D．Disease-sleeping has been caused．

What have spread diseases?

A．Disease-sleeping sickness．	B．Measles．
C．Improved communications．	D．Malaria．

We make a nature sanctuary for rare birds but __________

A．some common and hardy kind of bird multiplies

B．rare kinds multiply

C．all bird multiply

D．no bird multiply

The main idea of the passage is _________．

A．that man is deliberately destroying the balance of nature

B．that man has foreseen the consequences of altering the balance old nature

C．that improved communications have changed history

D．that man is altering the balance of nature

An annoying problem for humans, who like to boast (夸耀) about all the distant planets and moons we have explored, is that we've never taken a good look right under our noses. The inside of the earth is relatively close, but how can we get there?
The deepest oil well enters a mere six miles into the crust (地壳) (the center of the earth is about 4,000 miles deeper). Russian scientists dug the deepest hole in Siberia, but bottomed out at about 7.5 miles below the surface. The Mohole project, a U.S. plan in the 1950s, called for drilling a hole 25 miles down to the boundary between the hard rocks of the crust and the soft mantle (地幔). Sadly the project involved government supporting.
It gets harder and harder to drill deep into the earth because rocks get softer and softer. Hard but easily broken at the surface, rocks become plastic at depth, and the pressure caused by the weight of the overlaying crust --- about 52,800 pounds per square inch at a depth of ten miles, makes further drilling impossible.
What little we know about the inside of the earth (like the fact that there's a crust, a mantle, and a core) comes from indirect evidence, such as the analysis of earthquakes.
So maybe it's time for a thorough new method to explore the earth's inside. Scientist David Stevenson says we should forget about drilling holes. Instead, we should open a crack (裂缝).
Stevenson suggests digging a crack about a half mile long, a yard wide, and a half mile deep (not with a shovel) but with an explosion on the scale of a nuclear bomb. Next, he'd pour a few hundred thousand tons of molten (熔化的) iron into the crack, along with a robot. The iron, thicker than the surrounding crust, would move downward at about 16 feet per second, carrying the robot with it and opening the crack deeper and deeper. The iron mass would drop for about a week and 2,000 miles to the outer edge of the earth core, the robot sending out data to the surface.
Stevenson compares his idea to space exploration. "We're going somewhere we haven't been before,"he says. "In all possibility, there will be surprises.”
This idea can probably be put in the drawer marked with Isn't Going To Happen. The robot would have to survive temperatures that would melt pretty much anything. But Stevenson's idea may inspire a new look at an old problem. Great things can come from what seems like impossible ideas.
Going inside the earth is _____ than going into space.

C．It is a good proposal that will soon be put into practice.

On the New York set of the film Hide and Seek, ten-year-old Dakota Fanning spends her time playing a deeply disturbed girl who deals with her mother's suicide (自杀) by creating an imaginary friend, who may not frighten her family.
Today, though, she has the day off. "This week I only worked two days,"says Fanning, sitting in a sofa in her hotel's library, "but I get bored when I'm not working. Especially because it's cold here and I can't do anything, you know? So, I've been knitting (编织) --- all day, every day."The actress, who's held her own opposite Oscar winners such as Sean Penn and Denzel Washington, recently mastered the fine art of scarves (围巾). Though she's about ready to move on to hats, she first plans to make a souvenir (纪念品) scarf for Robert De Niro, who plays her father in the film. "He's the nicest guy you'd ever meet in your entire life,"she says, her voice dropping to a whisper. "I would make him a brown one.”
Like any other fifth-grader, Fanning spends several hours a day going to school. In addition to her personal trailer (活动住房) --- which is kept well-supplied with hot chocolate packets, lemon Gatorade, and a TV that doesn't always work --- she has another trailer where her teacher, Jan, conducts classes in history, spelling, reading, math, science and health. "We have this big board where we have a calendar (日历),"Fanning says. "When we were here in January, I wrote the calendar in all blue. February was red, and March was green.”
On this particular morning, she had a spelling test. "There was a topic for each of the word lists,"she says, sitting on her knees. "This one was flowers --- they were all names like oxygen, carbon dioxide, chrysanthemum (菊花)..."Chrysanthemum? "Well, they didn't make me spell that one. They just had me fill in the ‘e'. But I can spell it: c-h-r-y-s-a-n-t-h-e-m-u-m.”
