It doesn' t feel like it, but we got a raise this week. The sliding price of oil, which made OPEC decide to announce a production cut, has put money in the pockets of consumers, who worry about the world - wide recession(經(jīng)濟(jì)衰退).

      The high price of gasoline has greatly changed driving patterns, perhaps permanently "We are seeing changes in habits. " says Julian Lee from the Center for Global Energy Studies in London. People now prefer to buy small cars instead of gas - guzzling SUVs. If we see this change it becomes a much longer term issue with long - term demand destruction.

     In the short term, there' s simple math. The price slide could save drivers a great deal of money. However, because the U.S. is out of its peak summer driving season, there' s not too much of an encouragement to drive a lot more just because gas prices are down.

     Oil demand in the U.S. has dropped 10% in the few weeks, continuing a year long

trend. According to the U.S. Department of Transportation, Americans drove 15 billion fewer miles in August, or 5.6% less than they did the year before. DOT says it' s the largest ever year -to -year decline recorded in a single month.

      Due to falling worldwide demand, oil price dropped to its lowest level in more than a year.For months leaders of oil - rich countries have watched nervously as world oil prices have been more than 50% lower than the all - time high in July.

      All of which spells disasters for OPEC. Iran and Venezuela have pushed fellow OPEC members to make big enough cuts in production to change the plunge in prices in Vienna on Thursday for OPEC' s emergency meeting. OPEC countries' method of fixing their combined out - put has for years hugely influenced world prices, since OPEC' s 13 members account for about one - third of the world' s total oil supplies.

 

7l. According to the passage, "we got a raise dais week" because __  

     A. the consumers seldom use their cars at present

     B. we' II face financial problems in the recession

     C. the OPEC countries will buy us gasoline fro cars

     D. we' II spend much less money on gasoline for cars

72. In the writer's opinion, the reason people prefer to small ears is that __  

     A, small cars are more beautiful than SUVs

     B. SUVs will cause much more air pollution

     C. small cars cost much less on gasoline than SUVs

     D. SUYs waste too much energy and pollute the air

73. The following statements are all true except __  

     A. Americans drove about 15 billion fewer miles this year

     B. oil demand in America has been dropping for one year

     C. "DOT"" stands for the U.S. Department of Transportation

     D. more cars are on the road in summer than in other seasons

74. The underlined word "plunge" in the last paragraph most probably means 

     A. the action of pulling up              B. delaying or putting off

 C. sudden~ moving downward          D. severe financial problem

The computer keyboard helped kill shorthand—a system of rapid handwriting, and now it’s threatening to finish off handwriting as a whole. When handwritten essays were introduced on the SAT exams for the class of 2012, just 15% of the most1.5 million students wrote their answers in cursive(草寫(xiě)字母). The rest? Block letters.

And those college hopefuls are just the first edge of a wave of US students who no longer get much handwriting instructions in the primary grades, frequently 10 minutes a day or less. As a result, more and more students struggle to read and write cursive.

At Keene Mill Elementary School in Springfield, all their poems and stories are typed. Children in Fairfax County schools are taught keyboarding beginning in kindergarten. Older students who never mastered handwriting say it doesn’t affect their grades.

There are those who say the culture is at a crossing, turning from the written word to the typed one. If handwriting becomes a lost form of communication, does it matter?

It was at University Virginia that researchers recently discovered a previously unknown poem by Robert, written in his unique script. Handwritten documents are more valuable to researchers, historians say, because their authenticity(真實(shí)性) can be confirmed. Students also find them more fascinating.

The loss of handwriting also may be  a cognitive(認(rèn)知的) opportunity missed. Several academic studies have found that good handwriting skills at a young age can help children express their thoughts better—a lifelong benefit.

It doesn’t take much to teach better handwriting skills. At some schools in Prince George’s County, elementary school students use a program called Handwriting Without Tears for 15 minutes a day. They learn the correct formation of manuscript letters through second grade, and cursive letters in third grade.

There are always going to be some kids who struggle with handwriting because of their particular neurological(神經(jīng)系統(tǒng)的) writing, learning issues or poor motor skills. Educators often point to this factor in support of keyboarding.

1.What is the author concerned about after 2012 Sat exams?

A. Keyboarding.      B. Shorthand.      C. Handwriting.     D. Block letters.

2.A poem by Robert mentioned in the passage is used to ____________.

A. prove how valuable handwriting is          

B. explain what a famous poet he is

C. show how unique his poem is        

D. stress how fascinating the documents are

3.The example of Handwriting Without Tears helps to argue that _____________. 

A. the schools are responsible for the loss of handwriting

B. the loss of handwriting is a cognitive opportunity missed

C. it doesn’t take much to teach better handwriting skills

D. the culture is turning from the written word to the typed one

4.According to the author, when is a perfect time to learn handwriting?

A. Kindergarten.                 B. Primary school.       

C. High school.                  D. College.

5.What is the author’s attitude towards this debate? 

A. Devotion.       B. Encouragement.        C. Critical.        D. Objective.

What will power your house in the future?Nuclear,wind,or solar power?According to scientists at the Massachusetts Institute of Technology (MIT) in the US,it might be leaves — but artificial (人造的) ones.

Natural leaves are able to change sunlight and water into energy. It is known as photosynthesis (光合作用).Now researchers have found a way to imitate this seemingly simple process.

The artificial leaf developed by Daniel Nocera and his colleagues at MIT can be seen as a special silicon chip with catalysts (催化劑).Similar to natural leaves,it can split water into hydrogen and oxygen when put into a bucket of water. The hydrogen and oxygen gases are then stored in a fuel cell,which uses those two materials to produce electricity,located either on top of a house or beside the house.

Though the leaf is only about the shape of a poker card,scientists claimed that it is promising to be an inexpensive source of electricity in developing countries. “One can imagine villages in India and Africa not long from now purchasing an affordable basic power system based on this technology,” said Nocera at a conference of the American Chemical Society.

The artificial leaf is not a new idea. The first artificial leaf was invented in 1997 but was too expensive and unstable for practical use. The new leaf,by contrast,is made of cheap materials,easy to use and highly stable. In laboratory studies,Nocera showed that an artificial leaf prototype (原型) could operate continuously for at least 45 hours without a drop in activity.

The wonderful improvements come from Nocera's recent discovery of several powerful,new and inexpensive catalysts. These catalysts make the energy transformation inside the leaf more efficient with water and sunlight. Right now,the new leaf is about 10 times more efficient at carrying out photosynthesis than a natural one. Besides,the device can run in whatever water is available;that is,it doesn't need pure water. This is important for some countries that don't have access to pure water.

With the goal to “make each home its own power station” and “give energy to the poor”,scientists believe that the new technology could be widely used in developing countries,especially in India and rural China.

1.Which of the following orders correctly shows how the artificial leaf is used to produce electricity?

a.a(chǎn)rtificial leaves split water into hydrogen and oxygen

b.the hydrogen and oxygen gases are stored in a fuel cell

c.the artificial leaves are put in water

d.the fuel cell uses hydrogen and oxygen to produce electricity

A. c,a,b,d                               B.c,b,a,d  

C.b,c,a,d                 D.c,a,d,b

2.The purpose of the scientists at MIT in developing the new artificial leaf is to________.

A.build up more power stations in the world

B.provide cheaper energy for developing countries

C.offer people in developing countries access to pure water

D.gain a deeper understanding of the photosynthesis process

3.The main idea of this passage is ________.

A.a(chǎn)n introduction to the history of artificial leaves

B.a(chǎn) mixture of water power and solar energy

C.giving energy to the poor

D.a(chǎn)n invention copying photosynthesis
