　　To many web building spiders, most of whom are nearly blind, the web is their basic 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 man isolated on an island of solid rock, totally out of touch and for sure to starve to death.

　　So important is the web to a web spider's survival that the animal will continue to construct new webs daily even if it is being straved. For 16 days the starving spider builds completely normal webs. Then, as the animal gets much thinner, it constructs a web using fewer strands. Such webs would only trap larger prey, which is more economical from the view of a starving spider.

　　The spider preserves energy by recycling web protein (蛋白质). It simply eats its own web each evening and re - uses it to manufacture new silk. In studies with redioactively labeled materials, it was found that 95 percent of web proten reappears in the next day's web. Most of the energy needed for web - building is used in walking over the strands (线，绳) 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 (无脊椎动物). If web - building is interrupted, or if some of the existing strands are destroyed, the spider simply retraces its steps to see where the web is left off and then finishes building a normal web. One spider will even finish building the incomplete web of another.

1．That a spider is able to finish an incomplete web of another proves that ________.

[　　]

A．a spider re - uses its web energy to reproduce new silk

B．spiders have a highly preprogarmmed brain

C．the web is everything to a spider

D．a spider is able to mend a destroyed web

2．A spider preserves its energy ________.

[　　]

A．because it constructs new webs daily

B．as it walks over the strands it lays

C．by eating its own web protein and then re - using it in the new web

D．by eating only in the evening

3．Without its web a web - building spider would NOT be able to ________.

[　　]

4．The underlined word “isolated” in the first paragraph means ________.

[　　]

Legos （乐高玩具）

    Architecture lovers in Washington do not have to travel far to see some of the world’s must famous building. Architect Adam Reed Tucker has rearrested fifteen of them using Lego bricks. The exhibit is called “LEGO Architecture: Towering Ambition.” It is at the National Building Museum in Washington until early September.

　　Lego bricks are small, colorful plastic blocks. They can be snapped together to make any number of objects. They are popular with children of all ages around the world.

　　Adam Reed Tucker calls himself an “architectural artist.”

　　He was a professional architect for ten years. After the terrorist attacks against the United States in two thousand one he decided to do something different. He wanted to express his feelings for the form of the skyscraper while deepening his understanding of architecture, engineering and construction. He chose to use something that most people used as children and could relate to.

　　The buildings in the exhibit include the World Trade Center in New York that was destroyed in the terrorist attacks; the Gateway Arch in Saint Louis, Missouri; the famous house called Fallingwater in Pennsylvania, designed by Frank Lloyd Wright; and the Burj Khalifa in Dubai, the tallest building in the world. Tucker used more than four hundred fifty thousand Legos to make his version which is more than five meters tall.

　　Tucker does all his work by hand, using only pictures of the buildings. He does not use any computers or drawings to plan his buildings. While the exhibit is going on, Tucker will be working on his latest work, the White House where the American president lives. Visitors can watch him create the famous building brick by brick.

　　Anne Bennett visited the Building Museum with her two grandchildren, Dylan and Daisy. She used the Lego exhibit to teach her grandchildren about famous buildings.

“My favorite is probably that tall building because it’s made out of Legos. It’s really cool because it looks like there’s individual little rooms.” Said Daisy.

What Daisy was talking about is the Willis Tower, formerly known as the Sears Tower in Chicago, Illinois. The real building is over four hundred forty meters tall. Tucker’s model stands six meters tall.

　　After walking through Tucker’s models, visitors can create their own works at the building station. They can make houses, office buildings, stores or factories. They can then place their models on a large map of a city. As more visitors come, the Lego city will grow.

　　To many people, Legos might seem like toys for kids. But Adam Reed Tucker proves that the only limit to what the toy can do is a person’s imagination.
