Science Daily (Apr 27, 2008) — Dutch ecologist Roxina Soler and her colleagues have discovered that subterranean (地下的) and aboveground herbivorous (食草的) insects can communicate with each other by using plants as telephones. Subterranean insects issue chemical warning signals through the leaves of the plant. This way, aboveground insects are warned that the plant is already “occupied”.
Aboveground, leaf-eating insects prefer plants that have not yet been occupied by subterranean root-eating insects. Subterranean insects send out chemical signals through the leaves of the plant, which warn the aboveground insects about their presence. This messaging makes it possible for spatially-separated insects to avoid each other, so that they do not compete for the same plant.
In recent years it has been discovered that different types of aboveground insects develop slowly if they feed on plants that also have subterranean residents and vice versa (反之亦然). It seems that a system has developed through natural selection, which helps the subterranean and aboveground insects to notice each other. This avoids unnecessary competition.
Through the “green telephone lines”, subterranean insects can also communicate with a third party, namely the natural enemy of caterpillars (毛虫). Parasitic wasps (寄生的黄蜂) lay their eggs inside aboveground insects. The wasps also benefit from the signals sent by the leaves, as these help them find more insects for their eggs.
The communication between subterranean and aboveground insects has only been studied in a few cases. It is still not clear how widespread this phenomenon is. But scientists are looking into it. This research was carried out at the Netherlands Institute for Ecology (NIOO-KNAW) by Roxina Soler, Jeffrey Harvey, Martijn Bezemer, Wim van der Putten and Louise Vet. The PhD project, in which this study was carried out, was funded by the Free Competition of NWO Earth and Life Sciences.

The old shopkeeper led me through to the back of the shop．The room was filled with boxes and
photographs of people dressed in old-fashioned clothes，holding packages in their hands．
“Who are these-people?”I asked．
“Satisfied customers，”answered young Mr. Hopkins．“We have a very wide choice of items for
sale．Whenever I serve a new customer, I always take their picture．”Mr. Hopkins pointed to an ancient
camera standing next to one wall．“Now, how can I serve you?”he added．
By this time，I had started to trust Mr. Hopkins and had begun to appreciate the lovely items on
sale. I needed to buy Christmas presents for my family and friends，and this seemed to be the perfect
place to purchase them．I spent a very pleasant hour being shown the commodities in Mr. Hopkins’shop．
No matter what I asked for, Mr. Hopkins found it for me．Finally, I bought an antique jewelry box，a pair
of riding boots，a leather-bound edition of the Complete Works of Mark Twain, and a sewing machine．
I was very excited that I had found such a good little shop．I promised Mr. Hopkins that l would
come back soon. “I will tell all my friends about your lovely place，”I told the shopkeeper．
“Please do not do that, sir" , said Mr. Hopkins．“This is a special place for special people．You must
keep this shop a secret．” Then he took my photograph and handed me the picture straight away．
“That was quick!”I exclaimed．I looked at the photograph．In the picture I looked proud and excited holding the presents I had bought in Mr. Hopkins’dusty shop．
On Christmas Day, my friends and relatives were delighted with the presents I had bought for them．
For weeks．my brother begged me to show him where to find this wonderful little shop．I finally agreed to take him to London to show him．
When we arrived in London，we walked along Oxford Street，past the department store and
Found nothing．The little shop was no longer there．In its place was an empty space being used as a car
park．I checked the area again。There was the music shop，and there was the department store．In between
should have been Hopkins and Son, but it wasn’t there．
As l was staring at the place where the shop should have been, a old policeman came along．“Are
you looking for something sir?”he asked．
I turned and said“I am looking for a little shop called Hopkins and Son．I thought it was here．”
“Oh yes，”said the policeman．“There was a shop here once called Hopkins and Son．It sold all
sorts of things，but it was knocked down over 30 years ago．”

"There's no other way to describe it, it's the moment of a lifetime," said Bigelow at the awards ceremony in Los Angeles on Sunday．She has become the first female ever to win a Best Director Oscar．
Bigelow was up against the top-selling film of all time, Avatar．But Bigelow's smallbudget film, The Hurt Locker, swept the awards with six trophies （奖杯） , including Best Director, Best Original Screenplay, Best Sound Mixing and the big one: Best Picture．
Many Hollywood insiders are calling this year’s awards the "Indie Oscars", with smaller films taking the other top awards．This was due in large part to outstanding individual performances: Jeff Bridges in Crazy Heart （Best Actor） and Sandra Bullock in The Blind Side （Best Actress）．But all eyes were on Bigelow, as her movie The Hurt Locker beat Avatar to the major awards．This was sweetened by the fact Avatar's director, James Cameron, is her ex-husband．
Bigelow was only the fourth female ever to be nominated （提名） for Best Director．She followed in the footsteps of Lina Wurtmuller, for Seven Beauties （1976）; Jane Campion, The Piano （1993）;and Sophia Coppola, Lost in Translation （2003）．
Bigelow played down the important occasion last week, telling CBS, "There's really no difference between what I do and what a male filmmaker might do．I mean we all try to make our days, we all try to give the best performances we can, we try to make our budget, we try to make the best movie we possibly can．So in that sense it's very similar．On the other hand, I think the journey for women, no matter what field it is—politics, business, film —it's a long journey．"
Ironically Bigelow's filmography is filled with action movies that are low on female leads and high on guns and steel．Her films such as Point Break and The Hurt Locker focus on the fears of men．
And is there an entertaining end to the story of Bigelow's victory? She won on International Women's Day．
It is, after all, Hollywood．
64．Of all the awards mentioned in Paragraph 2, the most important one is .
A．Best Picture B．Best Sound Mixing
C．Best Director D．Best Original Screenplay
65．We may learn from the passage that _____．
A．four people have been nominated for Best Director
B．The Hurt Locker cost a large sum of money
C．only big films such as Avatar can take top awards
D．Sophia Coppola was a woman director
66．What Bigelow said in Paragraph 5 indicates that women _____．
A．can't compete with men in any field
B．have to make greater efforts in whatever field
C．are weaker than men in the film industry
D．don't have to make a long journey until their careers take off
67．What would be the best title for the passage?
A．Oscar Awards Ceremony B．First Female Oscar Best Director
