    Philo Farnsworth was a man who made it possible for one of the most important communication devices (设备)- television to be created. Philo was born on August 19th, 1906, near Indian Creek in the western state of Utah. He attended a very small school near his family's farm. He did very well in school. He asked his teacher for special help in science. The teacher began helping Philo learn a great deal more than most young students could understand.

One night, Philo read a magazine story about the idea of sending pictures and sound through the air. Anyone with a device that could receive this electronic information could watch the pictures and hear the sound. The magazine story said some of the world's best scientists were using special machines to try to make a kind of device to send pictures. 

14-year-old Philo decided these famous scientists were wrong and that mechanical devices would never work. He decided that such a device would have to be electronic. Philo knew electrons(电子)could be made to move extremely fast. All he would have to do was to find a way to make electrons do the work. 

Very quickly Philo had an idea for such a receiver. It would trap light in a container and send the light on a line of electrons. Philo called it "light in a bottle".

Several days later, Philo told his teacher about a device that could capture (捕捉)pictures. He drew a plan for it, which he gave his teacher. Philo's drawing seemed very simple, but it clearly showed the information needed to build a television. In fact, all television equipment today still uses Philo's early idea.

Philo Farnsworth was only 14 years old then. He knew no one would listen to a child. In fact,  experts say that probably only ten scientists in the world at that time could have understood his idea.

On September 7th, 1927, Philo turned on a device that was the first working television receiver. The image produced on the receiver was not very clear, but the device worked. In 1930, the United States government gave Philo patent documents. These would protect his invention from being copied by others.

1.How did Philo get the idea of inventing a television?

A.By learning from his science teacher.

B.By reading a story in a magazine.

C.By thinking hard on his own.

D.By using his knowledge about electrons.

2.The underlined word "it" in the fourth paragraph refers to     .

A.a container sending pictures and sound through the air

B.a receiver that holds light and sends it on a line of electrons

C.a light box with a line of electrons in a bottle

D.a way to make electrons send pictures quickly

3.What can we learn about Philo?

A.His interest in science was raised by his teacher.

B.He made the first television receiver himself.

C.He received patent documents at the age of 24.

D.He found the famous scientists wrong after showing his teacher a plan.

4.We can infer from the text that Philo's idea     .

A.was not recognized at first

B.was only understood by his teacher

C.was turned into a television receiver immediately

D.was widely used in all television equipment in 1927

 

1.B 2.B 3.C 4.A 【解析】 这是一篇记叙文。文章讲述了电视发明人菲罗·法恩斯沃思是如何发明电视的。 1. 细节理解题。由第二段“One night, Philo read a magazine story about the idea of sending pictures and sound through the air. Anyone with a device that could receive this electronic information could watch the pictures and hear the sound. The magazine story said some of the world's best scientists were using special machines to try to make a kind of device to send pictures.”(一天晚上,菲罗在杂志上读到一篇关于在空中传送图片和声音的故事。任何人只要有一个可以接收这些电子信息的设备,就可以观看图片并听到声音。杂志的报道说,世界上一些最优秀的科学家正在使用特殊的机器,试图制造一种发送图片的装置。)和第三段中的“14-year-old Philo decided these famous scientists were wrong and that mechanical devices would never work. He decided that such a device would have to be electronic.”(14岁的菲罗认定这些著名科学家是错误的,机械装置永远不会工作。他决定这种装置必须是电子的。)可知菲罗是在杂志上读故事,才想到发明电视机的。故选B项。 2. 词句猜测题。由第四段“Very quickly Philo had an idea for such a receiver. It would trap light in a container and send the light on a line of electrons. Philo called it "light in a bottle".”(菲罗很快就想到了这样一个接收器。它将光困在一个容器里,然后把光传送到一条电子线上。菲罗称它为“瓶中之光”。)可推断出it 指代上文提到一种接收光,并将光发送到电子线上的接收器。故选B项。 3. 细节理解题。由第一段中的“Philo was born on August 19th, 1906, near Indian Creek in the western state of Utah.”(菲罗于1906年8月19日出生于犹他州西部印第安溪附近。)和最后一段中的“In 1930, the United States government gave Philo patent documents.”(1930年,美国政府给了菲罗专利文件。)可知菲罗在24岁(1930-1906=24)时获得专利。故选C项。 4. 推理判断题。由倒数第二段“Philo Farnsworth was only 14 years old then. He knew no one would listen to a child. In fact, experts say that probably only ten scientists in the world at that time could have understood his idea.”(菲罗·法恩斯沃思那时只有14岁。他知道没有人会听孩子的话。事实上,专家说当时世界上可能只有十位科学家能理解他的想法。)可推断出当时没人认可他的想法。故选A项。

    When a leafy plant is under attack, it doesn’t  sit quietly. Back in 1983, two scientists, Jack Schultz and Ian Baldwin, reported that young maple trees getting bitten by insects send out a particular smell that neighboring plants can get. These chemicals come from the injured parts of the plant and seem to be an alarm. What the plants pump through the air is a mixture of chemicals known as volatile organic compounds, VOCs for short.

Scientists have found that all kinds of plants give out VOCs when being attacked .It’s a plant’s way of crying out. But is anyone listening? Apparently. Because we can watch the neighbours react.

Some plants pump out smelly chemicals to keep insects away. But others do double duty. They pump out perfumes designed to attract different insects who are natural enemies to the attackers. Once they arrive, the tables are turned. The attacker who was lunching now becomes lunch.

In study after study, it appears that these chemical conversations help the neighbors .The damage is usually more serious on the first plant, but the neighbors, relatively speaking, stay safer because they heard the alarm and knew what to do.

Does this mean that plants talk to each other? Scientists don’t know. Maybe the first plant just made a cry of pain or was sending a message to its own branches, and so, in effect, was talking to itself. Perhaps the neighbors just happened to “overhear” the cry. So information was exchanged, but it wasn’t a true, intentional back and forth. Charles Darwin, over 150 years ago, imagined a world far busier, noisier and more intimate(亲密的) than the world we can see and hear. Our senses are weak. There’s a whole lot going on.

1.What does a plant do when it is under attack?

A.It makes noises. B.It gets help from other plants.

C.It stands quietly D.It sends out certain chemicals.

2.What does the author mean by “the tables are turned” in paragraph 3?

A.The attackers get attacked.

B.The insects gather under the table.

C.The plants get ready to fight back.

D.The perfumes attract natural enemies.

3.Scientists find from their studies that plants can ________.

A.predict natural disasters

B.protect themselves against insects

C.talk to one another intentionally

D.help their neighbors when necessary

4.What can we infer from the last paragraph?

A.The world is changing faster than ever.

B.People have stronger senses than before

C.The world is more complex than it seems

D.People in Darwin’s time were imaginative.

    When I was a boy, our extended, immigrant family would sometimes gather at my aunt’s tiny house over the summer. Relatives from all over the country would come in to visit. The adults would crowd together in the living room to talk and catch up on each other' s lives. And the kids would be sent out into the front yard to play when dinner was slowly cooked for all of us.

Those were the days before video games, smart phones, and motorized toys, so we often ended up playing an old game. I remember one of those moments especially. As I was the youngest and smallest of all the kids there, I got caught first and couldn't catch anyone else. My brothers and cousins were all too fast for me, and I grew more and more frustrated. I finally fell my face first into the dirt. I got up with tears forming in my eyes. Then I saw one of my female cousins Susan standing there. She started to run but was going much slower than before. I easily caught up and seized her. Then she turned to me, smiled, and said, I'm it! You d better run! Iran off laughing with glee while she turned and started to chase others.

Now I see how her act of kindness that day saved me from sadness and returned me to joy. It didn't matter that we hardly ever saw each other. I know we are family and she loves me.

In her wonderful book: Box of Butterflies, Roma Downey writes, "We are all one, we all belong to each other, and we are one big. beautiful family." Perhaps it is time that we all started to treat each other that way. Perhaps it is time that we shared our love, our kindness, our laughter, and our joy with everyone without fear. Perhaps it is time to finally and forever bring this world together in one big family reunion.

1.When the adults were chatting, the kids would__________.

A.play video games B.sit in the front yard

C.learn to cook dinner D.play traditional games

2.The author was able to catch Susan because________.

A.the others ran too fast B.the author was good at running

C.Susan gave her a chance D.Susan wanted to chase others

3.What can be inferred from the passage?

A.The author is grateful for hat Susan did to her.

B.The author cant meet Susan any more.

C.The author urges others to love their family.

D.The author believes the world will become a big family

4.What could be the best title of the passage?

A.A memory of my childhood. B.Sharing of goodness unites us.

C.Kindness brightens our life. D.A good deed is invaluable.

阅读下面短文,根据其内容写一篇60词左右的内容概要。

Environmental problems are becoming more and more serious all over the world. For example, cars have made the air unhealthy for people to breathe and poisonous gas is given off by factories. Trees on the hills have been cut down and waste water is being poured continuously into rivers. Furthermore, wherever we go today, we can find rubbish carelessly disposed(处理)

There are different kinds of pollutants, each of which comes from different sources. It is necessary to identify the source of pollution, in order to make a policy to get rid of them. Different products, processes and activities of our industrialized world together form the major source of pollution.

The forms of pollution can be mainly divided into three kinds—solidsliquid and gas. These pollutants have greatly damaged our planet and continue to do so. In factpollution is threatening our existence. The whole ecological balance of the earth is changing. Massive destruction of environment has brought about negative effects and even posed a great threat to man’s existence.

We must face the situation that exists and take action to solve our environmental problems. For instance, new laws must be passed to place strict control over industrial pollution; the public must receive the education about the danger of pollution and raise their awareness of protecting the environment and so on.

The earth is our home and we have the duty to take care of it for ourselves and our later generations. Fortunately, more and more people have realized these problems. Measures have been taken to deal with these situations by the government. And laws have been passed to stop pollution, I hope the problems will be solved in the near future and our home will become better and better.
