【題目】Directions: Read the following passage. Summarize the main idea and the main points of the passage in no more than 60 words. Use your own words as far as possible.

California condors are North American’s largest birds, will wing-length of up to 3 meters. In the 1980s, electrical lines and lead poisoning nearly drove them to dying out. Now, electric shock training and medical treatment are helping to rescue these big birds.

In the late 1980s, the last few condors were taken from the wild, and there are nowmore than 150 flying overCaliforniaand nearbyArizona,Utahand Baja inMexico. Electrical lines have been killing them off. “As they go in to rest for the night, they just don’t see the power lines,” says Bruce Rideout of San Diego Zoo. Their wings can bridge the gap between lines, resulting in electrocution(電死) if they touch two lines at once. So scientists have come up with a shocking idea. Tall poles, placed in large training areas, teach the birds to stay clear of electrical lines by giving them a painful but undeadly electric shock. Before the training was introduced, 66% of set-freed condors died of electrocution. This has now dropped to 18%.

Lead poisonous has proved more difficult to deal with. When condors eat dead bodies of other animals containing lead, they absorb large quantities of lead.This affects their nervous systems and ability to produce baby birds, and can lead to kidney failures and death. So condors with high levels of lead are sent to Los Angeles Zoo, where they are treated with calcium EDTA, a chemical that removes lead from the blood over several days. This work is starting to pay off. The annual death rate for adult condors has dropped from 38% in 2000 to 5.4% in 2011.

Rideout’s team thinks that theCaliforniacondors’ average survival time in the wild is nowjust under eight years. “Although these measures are not effective forever, they are vital for now,” he says. “They are truly good birds that are worth every effort we put into recovering them.”

【題目】 As the saying goes, “Without music, life would be a mistake.” Music is very important in our lives and here are four of the greatest musicians in history.

Ludwig van Beethoven(1770-1827)

Born in Bonn, Germany, Beethoven never held an official position in Vienna. He supported himself by giving concerts, teaching piano, and the sale of his compositions(作曲). The last 30 years of Beethoven’s life were filled with a lot of hard times, the first of which was his deafness. Beethoven’s music greatly influenced the next generation of musicians.

Johann Sebastian Bach(1685-1750)

Bach, “the father of modern music”, was born in Eisenach, Germany. His parents died when he was nine years old, and in 1695 he went to live with his brother Johann Christoph, who was an organist(風(fēng)琴手) in Ohrdruf. He stayed there until 1700. Seven years later, he moved back to Weimar, where he served as court(宮廷) organist for nine years. His music greatly influenced classical music.

Frederic Chopin (1810-1849)

Chopin was born in Zelazowa Wola, Poland. He showed a talent for the piano at a very young age. Chopin began composing when he was still a child, but some of his early works have been lost. He gave his first public concert in 1818. Chopin was considered as the leading musician of his time.

Franz Schubert(1797-1828)

Schubert was born and died in Vienna. Unlike most of his predecessors(前輩),Schubert was not a great performer. He never had much money but he was very productive. He wrote his first masterpiece when he was only sixteen. However, he died young, before his talents had even been known.

【1】Beethoven did Not make a living by ___.

A.teaching studentsB.doing business

C.selling his worksD.giving concerts

You can relax if remembering everything is not your strong suit. Recent research makes the case that being forgetful can be a strength—in fact, selective memory can even be a sign of stronger intelligence.

Traditional research on memory has focused on the advantages of remembering everything. But looking through years of recent memory data, researchers Paul Frankland and Blake Richards of the University of Toronto found that the neurobiology（神經(jīng)生物學(xué)） of forgetting can be just as important to our decisionmaking as what our minds choose to remember.

“The goal of memory is not the transmission of information through time. Rather, the goal of memory is to help improve decisionmaking. As such, transience(轉(zhuǎn)瞬即逝) is as important as persistence in memory systems，” their study in Neuron states.

Making intelligent decisions does not mean you need to have all the information at hand, it just means you need to hold onto the most valuable information. And that means clearing up space in your memory palace for the most uptodate information on situations. Our brains do this by generating new neurons(神經(jīng)元) in our hippocampus(海馬體), which have the power to overwrite existing memories that are influencing our decisionmaking.

“If you're trying to deal with the situation and your brain is constantly bringing up multiple conflicting memories, that makes it harder for you to make a wise decision，” Richards told Science Daily.

If you want to increase the number of new neurons in your brain's learning region, try exercising. Moderate aerobic exercise like jogging, power walking, and swimming have been found to increase the number of neurons making important connections in our brains.

When we forget the names of certain clients and details about old jobs, our brain is making a choice that these details do not matter. Although too much forgetfulness can be a cause for concern, the occasional lost detail can be a sign of a perfectly healthy memory system. The researchers found that our brains facilitate decisionmaking by stopping us from focusing too much on minor past details. Instead, the brain promotes generalization, helping us remember the most important gist of a conversation.

“One of the things that distinguishes an environment where you're going to want to remember stuff versus an environment where you want to forget stuff is this question of how consistent the environment is and how likely things are to come back into your life，” Richards said.

If you're an analyst who meets with a client weekly, your brain will recognize that this is a client whose name and story you need to remember. If this is someone you may never meet again, your brain will weigh that information accordingly.

These findings show us that total recall can be overrated. Our brains are working smarter when they aim to remember the right stories, not every story.

Title：Being Forgetful Might Actually Mean You're 【1】

【題目】WHAT WOULD YOU DO WITH A DOLLAR？

AMERICAN DINNER-TABLE rules are simple：Don't discuss religion，politics，or money.

Money is especially bad. It makes people evil，small-minded and mean. Still，we want it. Little in life is simpler，or more symbolic of possibility，than a single George Washington. So we asked a handful of creative thinkers：What's the best way to invest a dollar？

■I would travel to an American post-industrial town，find a boardedup theater，and buy it for one dollar. Working with friends，I would rally（重整）the community together，raise money，and open it independently. This is what happened in the town of Cohoes，New York，and it can happen anywhere.

DEV AUJLA，founder of DreamNow

■Buy a newspaper which provides a credible source of news. It's cheap, it's informative, and staying current will help you strike up a conversation with people who could help advance your career.

ROB FRIEDMAN, a risk associate

■In my travels, I'd say that what people need most besides security and education is access to clean drinking water. So I'd give the dollar to a nonprofit or tech company that provides water sources to communities in need. A simple well with a solar-powered pump might have met their temporary needs.

BEN HARRISON, a U. S. Marine

■I would bury the dollar in the most beautiful place I could find，then create an elaborate（復(fù)雜的）map to the dollar.I would hope someone would discover this map years from now and have an adventure to go on.

PHILP STOCKTON，a filmmaker
