题目内容

  The United States Environmental Protection Agency says only seven per cent of plastic waste in the United States is recycled each year. A new compa?ny in northern New York says it can increase that percentage. It also says it can help the United States reduce the amount of oil it imports.

  The company has a machine named the "plastic-eating monster". Every hour,thousands of kilograms of milk jugs,water bottles,and grocery bags are fed into the machine. The plastic waste comes from landfills across the United States. John Bordnyniuk runs the company,called JBI.

  Mr Bordnyniuk has invented a new process for turning plastic into fuel. First,many different kinds of unwashed plastics are melted together.

Mr Bordnyniuk uses a special chemical to turn the liquid into a vapour. This reduces the plastic to its most basic elements.

  "Plastics are just long hydrocarbon chains. What we're doing is reforming them into links and chains that we want so they have a high fuel value.” Eight per cent of the recycled plastic is used to run the system. Independ?ent testers say eighty-six per cent of what goes in comes out as fuel.

  Bob Molodynia helps run the company. He watches as the plastic-eating machine pours a thin,brown liquid into an oil barrel.

  JBI produces several thousand liters of fuel a day. It creates different grades of fuel for different industries. It sells the fuel for up to one hundred dollars a barrel. Each barrel costs about ten dollars to produce.

  Scientists say plastic-to-oil technology is still new and developing. They say it is not yet known if the process is environmentally friendly. And some questions whether turning plastic into oil can even be considered "recycling".

  Carson Maxted is with the publication Resource Recycling,a magazine that reports on the plastic recycling industry. He says because there is a lot of plastic waste and a great demand for oil,JBFs recycling technology may create great changes in both industries.

1. What should be the best title of the passage?

   A. Could waste plastic reduce our need for oil?

   B. How can waste plastic be changed into oil?

   C. What should we do to reduce the import of oil?

   D. What is the "plastic-eating monster"?

2. What is the purpose of using a special chemical?

   A. To melt the unwanted plastic.

   B. To turn liquid plastic into vapour.

   C. To turn plastic into fuel.

   D. To make the machine use more plastic.

3. From the passage,we know      .

   A. there is a great profit for JBI to turn waste plastic to oil

   B. plastic-to-oil technology is very developed in America

   C. the process of turning plastic into fuel is environmentally friendly

   D. JBI's recycling technology must create great changes in the plastic re?cycling industry

4. Who is the boss of JBI?

   A. Carson Maxted.

   B. John Bordnyniuk.

   C. Bob Molodynia.

   D. Machiel Smiths.

[文章大意]本文是一篇说明文。文章介绍了美国一家新公司jbi把废弃的塑料变成油的新技术,这可能会让塑料循环行业和油需求有所改变。

1. A主旨大意题。根据文章第一段以及最后一段中的"… JBI's recycling technology may create great changes in both industries."可知,本文所讲述的是一家美国公司将废弃的塑料变成油的过程以及可能对美国处理废弃垃圾以及油的进口产生的影响。故选A项。

2. B细节理解题。根据第四段中的"MrBordnyniukusesa special chemical to turn the liquid into a vapour. "Hj"知选b项。

3. A推理判断题。根据倒数第三段中的"It sells the fuel for up to one hundred dollars a barrel. Each barrel costs about ten dollars to produce."可知,卖一桶油是100美元,每桶油的生产费用是大约10美元。故选a项。

4. B细节理解题。根据第二段中的"John Bordnyniuk runs the company,called肌"可知选B项。

  Women are friendly. But men are more competitive. Why? Researchers have found it’s all down to the hormone oxytocin (荷尔蒙催生素) .Although known as the love hormone,it affects the sexes differently.

 “Women tend to be social in their behaviour. They often share with others. But men tend to be competitive. They are trying to improve their social status ,” said Professor Ryan.

 Generally,people believe that the hormone oxytocin is let out in our body in various social situations and our body creates a large amount of it during positive social interactions (互动) such as falling in love or giving birth.

  But in a previous experiment Professor Ryan found that the hormone is also let out in our body during negative social interactions such as envy.

  Further researches showed that in men the hormone oxytocin improves the ability to recognize competitive relationships,but in women it raises the ability to recognize friendship.

  Professor Ryan’s recent experiment used 62 men and women aged 20 to 37.

Half of the participants (参与者) received oxytocin. The other half received placebo (安慰剂).

  After a week,the two groups switched with participants. They went through the same procedure with the other material.

  Following each treatment,they were shown some video pictures with different social interactions. Then they were asked to analyze the relationships by answering some questions. The questions were about telling friendship from competition. And their answers should be based on gestures,body language and facial expressions.

  The results indicated that,after treatment with oxytocin,men’s ability to correctly recognize competitive relationships improved,but in women it was the ability to correctly recognize friendship that got better.

Professor Ryan thus concluded, “Our experiment proves that the hormone oxytocin can raise people’s abilities to better distinguish different social interactions. And the behaviour differences between men and women are caused by biological factors (因素) that are mainly hormonal. ”

(   ) 1. What causes men and women to behave differently according to the text?

   A. Placebo.

   B. Oxytocin.

   C. The gesture.

   D. The social status.

(   ) 2. What can we learn from Professor Ryan’s previous experiment?

   A. Oxytocin affects our behaviour in a different way.

   B. Our body lets out oxytocin when we are deep in love.

   C. Our body produces oxytocin when we feel unhappy about others’ success.

   D. Oxytocin improves our abilities to understand people’s behaviour differences.

(   ) 3. Why did Professor Ryan conduct the recent experi ment?

   A. To test the effect of oxytocin on the ability to recognize social interactions.

   B. To know the differences between friendship and competition.

   C. To know people’s different abilities to answer questions.

   D. To test people’s understanding of body language.

(   ) 4. The author develops the text by _________.

   A. explaining people’s behaviours

   B. describing his own experiences

   C. distinguishing sexual differences

   D. discussing research experiments
