It is like a scene from a horror film:a spider web is several meters wide,which is home to thousands of spiders.And that was what Jason G.Goldman,an animal behavior researcher,found along a muddy path in the Peruvian Amazon jungle—the web arched from tree to tree,a structure containing too many spiders to count.They appeared to function as a society,just like ants or bees.
Anelosimus eximius,the species Goldman met in the rainforest,is not the only kind of social spiders in the world,but it does construct the biggest webs.Some can reach more than 7.6m long and 1.5m wide.A web of that size could contain as many as 50,000 individual spiders.
Anelosimus eximius was first discovered more than a century ago by a French scientist named Eugene Simon.More social spiders have been discovered since.One was found as recently as 2006.
An Anelosimus eximius colony(群体) contains adult males and females as well as youngsters,but the majority of spiders on the web are females. Males account for only between 5% and 22% of any colony’s population.Social spiders work together to build,maintain and clean their webs.They work together to catch prey(猎物),and dine together when they trap a large feast.The females work together to care for the young in the colony.They feed their youngsters by vomiting(吐出) up food for them,just like mother birds.
Why did these spiders become social?Researchers have discovered three ecological(生态的) elements that often lead to cooperative(合作的) living among spiders.
Social spiders tend to feed on bigger prey,for one thing.Spiders living in places where it is difficult to hunt large or more profitable prey alone may eventually figure out that it is in their interest to work together.
1.What can we know about Anelosimus eximius from the text?
A. Its latest branch was found in 2006.
B. It was discovered by Jason G.Goldman.
C. It has been in existence for less than a century.

To many web-building spiders, most of whom are nearly blind, the web is their essential window on the world: their means of communicating, capturing prey, meeting mates and protecting themselves. A web-building spider without its web is like a men cast away on an island of solid rock,totally out of touch and destined to starve to death. So important is the web to an orb-web spider's survival that the animal will continue to construct new webs daily even if it is being starved. For 16 days the starving spider builds completely normal webs. Then, as the animal gets scrawnier, it constructs a wider-meshed (网孔、网眼)web using fewer strands(线). Such webs would only trap larger prey, which is more economical from the perspective of a starving spider. The spider stores energy by recycling web protein. It simply eats its own web each evening and reuses it to produce new silk. In studies with radioactivity, labeled materials, it was found that 95 percent of web protein reappears in the next day web. Most of the energy needed for web-building is used in walking over the strands as they are laid down. Scientists are impressed by the adaptability of the spider's highly preprogrammed brain, which is larger for its size than the brain of any other invertebrate(无脊推动物). If web-building is interrupted, or if some of the existing strands are destroyed, the spider simply goes back to see where the web is left off and then finishes building a normal web. One spider will finish building the incomplete web of another.
1.Which of the following best expresses the main ideas of the passage?
A. Secrets of Spiders' Adaptability
B. Importance of Webs to Spiders
C. Secrets of the Spiders' Life
D. Spiders' Highly Preprogrammed Brain
2.According to the passage, which of the following statements is TRUE?
A. Most spiders will stop conducting webs when hungry.
B. One Web-building spider usually conducts one web.
C. Web-building spiders will probably die without their webs.
D. Web-building spiders have good eyesight.
3.The underlined word “scrawnier” in the second paragraph probably means ______.
A. weaker but good-looking
B. fatter and stronger
C. nice and healthier
D. thinner and bony
4.A spider's ability to finish an incomplete web proves that ______.
A. it has a highly preprogrammed brain
B. it reuses its web protein to reproduce new silk
C. the web is everything for a spider
D. it is able to rebuild a destroyed web

It looks like a scene from the thriller movie Jaws,but these photos of a huge shark swimming with swimmers were in fact taken in Britain. The amazing pictures,which showed that the basking shark (姥鲨) was swimming friendly with swimmers,were taken at Porthcurno beach,Cornwall,where the basking shark was swimming just yards off shore.
The single 14foot giant was feeding in the shallow waters off the scenic area,and quickly became curious about the swimmers and surfers sharing the water. Though it came within touching distance,the swimmers and surfers were in no danger. The large sharks are plankton (浮游生物) feeders-unlike the man-eating Great White from Jaws.
Beach-goer Rachel Hosken,who took the pictures,said that several basking sharks had been seen in the area.“It is one of the few I have ever seen around this year and it was great to see,” she said excitedly.“There are usually more of them by now,but for some reason there are fewer around than normal at this time of year. I think more have been spotted in deeper waters,but the particular one in the pictures seems to have taken a liking to this spot. I have seen it a few times.”
Known as the gentle giant of the sea,the basking shark is the second largest fish in the sea,only weighing lighter than the whale shark. They can grow to over 36 feet (11 meters) and weigh up to seven tons (7,000 kilograms) and feed on a diet of plankton and small fish. Basking sharks normally begin to appear in May and June.
1.In the pictures taken by Rachel Hosken,we can infer that ________.
A.swimmers and surfers were escaping |
B.surfers were trying to frighten the basking shark |
C.the basking shark was swimming far from swimmers |
D.swimmers were not frightened by the basking shark |
2.Why didn’t the basking shark attack the swimmers or surfers?
A.Because it was not hungry. |
B.Because it was too far from them. |
C.Because it isn’t a man-eating shark. |
D.Because it enjoyed swimming with them. |
3.From what Rachel Hosken said we know that ________.
A.most basking sharks swim deep in the sea |
B.this basking shark has often appeared in that area |
C.many basking sharks have been killed in that area |
D.the basking shark doesn’t like being with other basking sharks |
4.What’s the best title for this passage?
A.A giant basking shark appeared in Cornwall,Britain. |
B.A giant basking shark tried to please the British people. |
C.Swimmers and surfers were frightened by a giant basking shark. |
D.Brave swimmers swam together with a giant basking shark. |

Those who plan to film a hostage (人质) scene might want to make it obvious to everyone around them that it' s a simulation.That may be the lesson that an independent film crew learned in Larimer County, Colo.after sheriff s deputies (治安警察) surrounded them during a shoot for a low -budget feature movie.Members of the crew were at a campground near Lake Carter, shooting a scene where the lead actor takes a girl hostage and beats up on a man who tries to intervene (干涉)."It happened very suddenly after that.We heard, 'freeze' " said Director Eileen Agosta.They were in the middle of the scene when a team of Larimer County sheriff s deputies ran over, shouting orders to get on the ground, pointing guns at the crew, actor Chris Borden said.Members of the crew were cuffed (戴上手铐) and held on the ground until the situation was sorted out.Borden said he believes the only reason the deputies didn't shoot him was because they saw a cameraman.Maj.Justin Smith of the Larimer County Sheriff s Department said deputies received a call from someone at the lake and sheriff s deputies raced to the park, blocking roads."I think it shows great self - control, great training and great judgment " said Cpl, Scott Shellhaas, a sheriff s spokesman."They didn't rush into the situation and make a potentially bad situation worse."Borden said the incident would have been funny except for the fact that he was issued a citation (传票) for disorderly conduct.Agosta was also cited for being an accessory to disorderly conduct."It was complete ignorance on my part," said Agosta."I honestly thought you could tell what we were doing… I wouldn' t have chosen a state park at 3 : 30 (p.m.) on Saturday if I was going to hurt somebody." Authorities said the scene they saw was realistic enough - - - a woman handcuffed to a car, a man handgun - striking another man, people injured and bloodied and someone with a small video camera filming the event."It is certainly not beyond belief these days that individuals do videotape crimes as they commit them," said Smith."Having a video camera there did not necessarily mean there was not a threat."
1.The underlined word probably means something that is ______.
A.not real B.really interesting
C.simply terrible D.seemingly true
2.The sheriff s deputies surrounded the film crew, because _____.
A.they found a girl hostage was terribly beaten
B.they were informed of a terrible scene at the lake
C.shooting a film was illegal at a state park in the county
D.they saw a cameraman shoot the hostage scene
3.According to the spokesman, the sheriff s deputies _____.
A.needed to be well trained later
B.made the situation from bad to worse
C.dealt with the situation successfully
