Philo Farnsworth is not a name most people know. But his work changed the way we learn, the way we live, and even the way we think. Philo Farnsworth is responsible for one of the 20th century: television.

Philo Farnsworth was born in America in 1906. He was interested in science and technology at an early age. When he was twelve years old, he built an electric motor for his family’s washing machine. When he was fourteen, he was already giving a lot of thought to electrons(电子). As he was driving the family’s horse-drawn plowing machine, he noticed the evenly spaced rows of the potato fields. This sight gave him the idea that electrons could scan(扫描) an image one row at a time—an idea that was the key to electronic television.

By the time he was twenty-one years old, Farnsworth had started his own company and had managed to build the world’s first electronic television. It was a very simple device(设备). But after years of hard work, Farnsworth was able to introduce the kind of television we now use.

Farnsworth was a great inventor, but lived an unhappy life. He had a legal battle with the company, Radio Corporation of America (RCA) over who the real inventor of the TV was. He won the case, but the government stopped companies from making TVs during the war, so Farnsworth didn’t make much money from the invention.

When Farnsworth was young, he imagined television as a convenient way for distant audiences to enjoy lectures by famous professors, or entertainment by the best symphonies(交响乐) and ballets. When he was older, television became much more popular, but he was very disappointed in the silly programs on TV. He even told his own son, “There’s nothing on it worthwhile, and we’re not going to watch it in this household.”

1.What can we learn about Philo Farnsworth?

A. He had a strong physical advantage.

B. He had strong powers of observation.

C. He had a strong interest in journalism.

D. He had a strong sense of responsibility.

2.The underlined sentence showed Farnsworth was legally recognized as ________.

A. the real founder of RCA

B. the real inventor of the TV

C. the greatest inventor of his time

D. the organizer of the battle with RCA

3.The last paragraph mainly tells us that Farnsworth ________.

A. didn’t like to watch TV programs

B. couldn’t afford to buy a TV set

C. couldn’t listen to famous lectures

D. didn’t like what television became

4.What is the best title for the text?

A. How did Philo Farnsworth invent television?

B. What caused Philo Farnsworth to invent television?

C. Philo Farnsworth: the unhappy father of television

D. Philo Farnsworth: a well-known scientist and inventor

The coyote (丛林狼), that clever animal of wide-open spaces, has come to the nation’s capital. In fact, coyotes have spread to every corner of the United States, changing their behaviors to fit new environments and causing researchers to deal with a troublesome new kind of creature: the city coyote.

The coyote originally lived in the middle of the continent. One of its most obvious characters is its smartness, which has made the animal a notorious (臭名昭著的) pest. Hunters trapped, shot and poisoned more than a million coyotes in the 1900s. It’s still one of America’s most hunted animals. Yet the coyote has survived. How has the coyote shown this extraordinary ability? “I guess if you wanted to use one word, it’d be ‘plasticity’,” says Eric Gese, an expert at Utah State University. Coyotes can live alone, in pairs, or in large packs like wolves; hunt at night or during the day; occupy a small region or an area up to 40 square miles; and live on all sorts of food, from lizards and shoes, to ants and melons.

Unbelievably people helped coyotes increase when they killed most of the wolves in the United States. The spreading of coyotes into city areas, though, is recent. They travel at night, crossing sidewalks and bridges, running along roads and ducking into culverts (钻入涵洞) and underpasses. No one knows why coyotes are moving into cities, but experts explain that cleverer, more human-tolerant (不怕人的) coyotes are teaching urban survival skills to new generations.

Occasionally, coyotes might attack human beings. There have been about 160 attacks on people in recent years. Therefore, people have been consistently told not to feed coyotes or leave pet food unsecured. That, plus a large trapping program in the neighborhood, has cut down on the coyote population.

1.The underlined word “plasticity” in Paragraph 2 refers to ________.

A. the ability to fit the environment

B. notorious smartness

C. hunting ability

D. being human-tolerant

2.The aim of the passage is to ________.

A. tell people how to fight against coyotes

B. tell us why the coyote is the most hunted animal

C. supply the reason why the coyote is a kind of notorious pest

D. explain how the coyote has spread to and survived in cities

3.According to the passage, coyotes ________.

A. originally lived in the west of the continent

B. sleep during the day but look for food at night

C. are teaching survival skills to their younger generations

D. suffered a population decrease because people killed wolves

4.According to the passage, to cut down on the coyote population, people are advised to ________.

A. leave pet food securedB. keep coyotes in small regions

C. force coyotes to live aloneD. avoid using trapping programs

根据短文内容,从短文后的选项中选出能填入空白处的最佳选项。选项中有两项为多余选项。

Money Matters

Parents should help their children understand money. 1. So you may start talking about money when your child shows an interest in buying things, candy or toys, for example.

1. The basic function of money

Begin explaining the basic function of money by showing how people trade money for goods or services. It is important to show your child how money is traded for the things he wants to have. If he wants to have a toy, give him the money and let him hand the money to the cashier(收银员). 2. When your child grows a bit older and understands the basic function of money, you can start explaining more complex ways of using money.

2. Money lessons

Approach money lessons with openness and honesty. 3. If you must say no to a child’s request to spend money, explain, — You have enough toy trucks for now. Or, if the request is for many different things, say, — You have to make a choice between this toy and that toy.

3. 4.

Begin at the grocery store. Pick out two similar brands of a product — a name-brand butter and a generic (无商标产品),for example. You can show your child how to make choices between different brands of a product so that you can save money. 5. If he chooses the cheaper brand, allow him to make another purchase with the money saved. Later, you may explain how the more expensive choice leaves less money for other purchases.

A. Wise decisions.

B. The value of money.

C. Permit the child to choose between them.

D. Tell your child why he can — or cannot — have certain things.

E. Ask yourself what things that cost money are most important to you

F. Talk about how the money bought the thing after you leave the toy store.

G. The best time to teach a child anything about money is when he shows an interest.

The guy who tried to edit English

The English vocabulary is not only huge, it is also full of words that mean practically the same thing. Get, obtain, acquire. Shine, gleam, glow, sparkle. 1.

That was the thinking of a British writer named C.K. Ogden, who in the 1930s promoted a new form of English with a vocabulary of just 850 words. He called the project Basic English. 2.

Ogden arrived at his 850-word list through experimentation. The words he finally included were not necessarily the shortest or most concrete. 3. Because any verbal (动词的) idea could be expressed with a small number of “operators”— words like come, go, take, have, make, be and do — Ogden argued that most verbs were unnecessary. In Basic English, eat is “have a meal” and forget is “go from memory.”

Winston Churchill was a fan of the concept as a way to get foreigners to speak English, and he encouraged the BBC to use it. 4. Roosevelt, who expressed mild interest, joked that Churchill’s famous speech about offering his “blood, toil, tears and sweat” to his country wouldn’t have been so exciting if he “had been able to offer the British people only blood, work, eye water and face water, which I understand is the best that Basic English can do with five famous words.”

5. Churchill didn’t use it either. When seeking to express ourselves, we don’t necessarily need fewer words; we need the right words. So it’s our benefit to have a large supply of words on hand.

A. Do we really need them all?

B. How many words are there in English?

C. Ogden himself didn’t actually use Basic English.

D. Plenty of seeming basic words did not make the list at all.

E. He also tried to persuade President Franklin Roosevelt to promote it.

F. He believed it would make the language more efficient and easier to learn.

G. Despite attention from world leaders, Basic English never got as far as expected.

Day 1

I first heard of “Show Racism (种族歧视) the Red Card” when my friend Jill asked me to support their work. Basically, it’s an organization which uses professional (职业的) footballers to help fight racism in sport and society. A few weeks later, he asked me if I wanted to do a bit more for them. I thought he probably meant for me to give money or do some voluntary work. But then he told me that a group of about 20 people were getting sponsored (赞助) to play the highest ever game of rugby (橄榄球) at 5,140 meters on Mount Everest.

Day 4

We’re making our way up to the base camp — that’s where most climbers start their final climb to the top — and then, we’ll play our game. Today we started out at 8 am. We had to cross three suspension bridges (悬索桥). One of them was so high that you couldn’t see the bottom. Then we walked through some beautiful forest areas before we started a two-hour uphill hike to Namche Bazaar.

Day 10

Base camp is basically just a lot of stones and tents. The walk up was really exhausting. Maybe if I was fitter, I wouldn’t find this so hard, but then it was not just me — all of us got very short of breath.

Day 11

Today we played our game. It was supposed to be a “friendly” game, and last night, we had agreed we’d just walk and not run. However, it was a really heated game and two players were even sent off. We only played for 14 minutes. I think someone would have got hurt if we’d played any longer! My team won and I scored the last try! Of course, none of this matters. What’s really important is that we did it and we’ve raised a load of money.

1.The first time the author was asked to do something for Jill’s work, he _____.

A. got a big shock

B. accepted his request

C. looked down upon Jill

D. spread the news to 20 people

2.What can we learn about the game of rugby on Mount Everest?

A. It got little attention.

B. It was a bit competitive.

C. It ended because someone was injured.

D. It was held on the top of Mount Everest.

3.The author’s trip to Mount Everest can be described as _____.

A. frightening and fruitless

B. relaxing and interesting

C. hard but successful

D. short but fantastic
