 "The world's oceans are slowly getting more acidic,”say scientists. The researchers from California report that the change is taking place in response to higher levels of carbon dioxide in the atmosphere.

    The lowering of the waters’pH value is not great at the moment but could cause a serious threat to current ocean life if it continues, they warn. Ken Caldeira and Michael Wickett, from the Lawrence Livermore National Laboratory, report their concerns in the journal Nature.

Increasing use of oil fuels means more carbon dioxide is going into the air, and most of it will eventually be absorbed by seawater. Once in the water, it reacts to form carbonic acid. Scientists believe that the oceans have already become slightly more acidic over the last century.

    These researchers have tried to predict what will happen in the future by combining what we know about the history of the oceans with computer models of climate change."This level of acidity will get much more extreme in the future if we continue releasing CO2 into the atmosphere," said Dr Caldeira. "And we predict the amount of future acidity will exceed(超过)anything we have seen over the last several hundred million years, let alone perhaps after rare disastrous events such as asteroid(小行星) impacts.”

    However, it is not absolutely clear what that means for ocean life.Most organisms live near the surface, where the greatest pH change would be expected to occur, but deep-ocean life forms may be more sensitive to pH changes.Coral reefs and other organisms whose shells contain calcium carbonate(小行星) may be particularly affected if the water's acidity levels keep going up, the team predict. They could find it much more difficult to build these structures in water with a lower pH.

    In recent years some people have suggested storing carbon dioxide from power stations in the deep ocean as a way of dealing with global warming.But Dr Caldeira said that such a strategy should now be re-considered. "Previously, most experts had looked at ocean absorption of carbon dioxide as a good thing-because in releasing CO2 into the atmosphere we warm the planet, and when CO2, is absorbed by the ocean, it reduces the amount of greenhouse warming.”

According to Dr Caldeira,__________ .

   A. ocean absorption of carbon dioxide is a good thing

   B. more oil fuels will be used in the near future

   C. scientists may predict climate changes with computer models

   D. the future situation of the amount of acidity is extremely serious

f the water's acidity level keeps rising,_________ .

   A. ocean life whose structures contain calcium carbonate may be affected

   B. the waters’pH value will become higher and higher

   C. organisms living near the surface are more sensitive to pH changes

   D. some disastrous events will occur more often than before

Most experts once believed storing carbon dioxide in the ocean would reduce________ .

   A. the CO2 absorbed by the ocean             B. the amount of greenhouse warming

   C. the acidity of the ocean                   D. the gradual release of CO2

The purpose of this passage is to_________ .

   A. show people the findings of a research team   B. inform people of how acid the ocean is now

   C. introduce Dr Caldeira and his team's research  D. warn people of the higher level of CO2

Mr. Frank shot well and once he had come in fourth in a competition.

Then he went to a big city on business. There he joined the local rifle club. The club had a very good team, which used to take part in a lot of important shooting competitions. One of these took place while Frank was with them. But one of the members of the club's team suddenly fell ill just before the match. The captain had heard of Mr. Frank.

Johnny was a cashier (收银员) in a large store. Every night when he came home from work, he would find a saying for the day and print it out on fifty pages of paper. Johnny would cut out each saying and sign his name at the bottom of each one. Then he would put them in a paper bag and put the bag beside him at work. Each time he finished bagging someone’s purchases, he would put one of his saying pieces in the customer’s bag as well. It touched me to think that this young man —with a job that most people thought not important —had made it important by creating precious memories for all of his customers. A month later the store manager called me and said, "Barbara, you won’t believe what happened today. When I went up to where the cashiers were, I found Johnny’s line was three times longer than anyone else’s! So I got more cashiers out there and opened more lanes (通道), but no one would move. They all said they wanted Johnny’s saying for the day." The store manager continued, "I got a lump in my throat when a woman came up to me and said, 'I used to shop at your store only once a week, but now I come in every time I go by for Johnny’s sayings.’" A few months later, the store manager called me again. "Johnny has changed our store completely," he said. "All of our cashiers now have their own personal signatures (签名). Everyone’s having a lot of fun creating good memories. Our customers are talking about us in a good way and are coming back with their friends."

Most students hate their endless homework. The students from Class 2, Senior 2 of the High School Affiliated to Peking University certainly did before they published their own collection of English novels at home.

Their small book contains stories about a holy (神圣的) war, the happy life of a self-taught artist and the story of a laid-off worker who devoted his last breath to playing his beloved accordion (手风琴). The book becomes an instant hit on campus. About 3,000 copies have been sold and the class is already working on the second volume.

"We're up to our ears in homework. Exercises and exams make us out of breath. But to do something creative and full of imagination is such a great achievement," said Yu Xiaoxiao, 16.

"I took the writing as an ordinary homework at the beginning, but after I finished the first part of my story, I could not help but let it flow," said Wang An, who wrote "Accordion".

Inspired by "Lord of the Rings", Jiang Lu wrote his story about magic wars between angels from the light and the dark side. "The main message of the story was to look at the balance of the world. Both dark and light angels fight with love as their weapons. I want to tell people that selfish love might bring hate," Jiang said.

"I was shocked by their work and felt so proud to be the editor of my students' book," said Nathaniel Timmermann, the oral English teacher at the school. Liu Xiuqin, an English teacher, started the project by asking students to write whatever was in their mind every week. "They have performed beyond expectation," Liu said. "They wrote interesting stories and their English has improved after they started to express their real minds."

"We never imagined that our homework would be so popular and profitable (盈利的). We sell the novels at five yuan, but many teachers pay more to encourage us," said Yuan Mengyao.

1. After Wang An finished the first part of his story, he _________.

A. couldn't go on                 B. had to put it aside   

C. just wanted to express it freely   D. lost it

2.What was not the outcome of the students' homework of writing whatever was in their mind?

A. Being popular.            B. Being profitable. 

C. Improving their English.    D. Winning prize.

3.What is the reason for the students' liking to write interesting stories?

A. It is creative and imaginative.             

B. It is profitable.

C. Interesting stories are sure to be popular.   

D. Interesting stories can be well sold.

4.What is the best title of this passage?

A. Creative homework leads to a popular book      

B. Writing interesting stories

C. Students' new book           

D. A popular book

 

As the United States nears the tenth anniversary of the 9/11 attacks that killed more than 3,000 people, President Obama announced Sunday night that the al Qaeda(基地组织) leader and mastermind of that horrific day, Osama bin Laden, has been killed.

CNN reports that a senior government official confirmed that bin Laden was shot by a small team of U.S. soldiers while in a mansion with family members outside Islamabad(伊斯兰堡). His body is now in American custody(拘押) and is being handled according to Islamic customs. Three other adult men were killed in the firefight, including a son of bin Laden's, who was a senior member of the terrorist organization.

"Justice has been done," the president announced, saying that the operation he ordered after receiving intelligence information is "the most significant achievement to date in our nation's effort to defeat al-Qaeda."

The immediate reactions ranged from cautious to ecstatic. Crowds cheered outside the White House. But officials said a "worldwide caution" would be set for Americans in case of al Qaeda retaliation(报复).

Will bin Laden's death be the justice Americans have sought for nearly a decade?

Gordon Felt, president of Families of Flight 93, said it does bring comfort.

"This is important news for us, and for the world. It cannot ease our pain, or bring back our loved ones. It does bring a measure of comfort that the mastermind of the September 11th tragedy and the face of global terror can no longer spread his evil," Felt said.

President Obama says this victory does not close the book.

"His death does not mark the end of our effort. There's no doubt that al Qaeda will continue to pursue attacks against us. We must and we will remain cautious," he noted.

1.The underlined word “ecstatic” most probably means _________.    

A. scared              B. extremely happy and excited

C. doubtful            D. amazed

2.The author mentions all of the items listed below EXCEPT_________. 

A. Four people were killed in the firefight.

B. Families of the victims in the 9/11 attacks celebrated together.

C. President Obama thought highly of the Anti-Terrorist Military Action

D. Obama thought that al Qaeda will continue attack against the United States.

3.It can be inferred from the text _________. 

A. The 9/11 attacks happened on September 11, 2001.

B. Osama bin Laden has three sons.

C. Some soldiers were injured in the firefight.

D. More than 3000 people were killed in the 9/11 attacks.

4.From the last paragraph we can learn that _________.  

A. Osama bin Laden’s death will put an end to terrorism.
