Recently, tests have proved that Beethoven died from lead poisoning. Bill Walsh directed the Beethoven Research Project. Mr. Walsh and his team examined pieces of bone belonging to Beethoven. They found a large amount of lead in the bone pieces. They said the lead levels were equal to those found in pieces of his hair in earlier studies of other scientists.
Genetic tests proved the bone pieces and his hair came from Beethoven. The research also examined bone fragments from someone else who lived during the same period. Both were from the top of the skull. The fragments from Beethoven had more lead than those from other person. Their study didn’t find measurable levels of cadmium(镉) or mercury(汞), which scientists used to consider were the causes of his health problems.
Beethoven was sick for much of his life. He experienced strong stomach pains, a sign of lead poisoning, and a change of personality when he was around 20. he also got angry easily, and suffered from depression and hearing loss. His health problems became worse as he grew older.
Walsh said the lead levels found in his skull suggested that the metal might have been present in his body for many years. He said although there had been recognized cases of deafness caused by lead poisoning, there was no strong evidence to suggest that lead poisoning was the cause of his deafness.
Beethoven visited many doctors to find a cure for his health problems, in a letter he wrote to a friend, he urged researchers to examine his body after he died so that other people would not have to suffer as he did.
61. If too much lead is in a person’s body, he will______.
A. suffer hearing loss             B. get angry easily
C. suffer serious stomach pains     D. lose most of his hair

A. this is the first research into the cause of Beethoven’s death
B. any amount of lead will do great harm to people’s health
C. more lead was found in Beethoven’s bones than in his hair
D. scientists used to think that his death was caused by other metals instead of lead
63. In which section of the newspaper might you read this report?
A. Health.   B. Technology.   C. Entertainment.   D. Culture.
64. What is the best title of the passage?
A. A surprising discovery about Beethoven   B. Beethoven died from lead poisoning

Parents often believe that they have a good relationship with their teenagers (青少年). But last summer, Joanna and Henry noticed a change in their older son: suddenly he seemed to be talking far more to his friends than to his parents . “The door to his room is always shut.” Joanna noted.
Tina and Mark noticed similar changes in their 14-year-old daughter. “She used to cuddle up (蜷伏)with me on the sofa and talk ,” said Mark . “Now we joke that she does this only when she wants something. Sometimes she wants to be treated like a little girl and sometimes like a young lady. The problem is figuring out which time is which.”
Before age 11, children like to tell their parents what’s on their minds. “In fact, parents are first on the list.” said Michael Riera, author of Uncommon Sense for Parents with Teenagers. “This completely changes during the teen years.” Riera explained. “They talk to their friends first, then maybe their teachers, and their parents last.”
Parents who know what’s going on in their teenagers’ lives are in the best position to help them. To break down the wall of silence, parents should create chances to understand what their children want to say, and try to find ways to talk and write to them. And they must give their children a mental break, for children also need freedom, though young. Another thing parents should remember is that to be a friend, not a manager, with their children is a better way to know them.
69. “The door to his room is always shut” suggests that the son        .
A. is always busy with his studies           B. doesn’t want to be disturbed
C. keeps himself away from his parents       D. begins to dislike his parents
70. What troubles Tina and Mark most is that        .
A. their daughter isn’t as lovely as before   B. they can’t read their daughter’s mind exactly
C. they don’t know what to say to their daughter
D. their daughter talks with them only when she needs help
71. Which of the following best explains “the wall of silence” in the last paragraph?
A. Teenagers talk a lot with their friends.
B. Teenagers do not want to understand their parents.
C. Teenagers do not talk much with their parents.
D. Teenagers talk little about their own lives.
72. What can be learned from the passage?
A. Parents are unhappy with their growing children.
B. Parents have suitable ways to talk with their teenagers.
C. Parents should be patient with their silent teenagers.
D. Parents should try to understand their teenagers.

Rising levels of carbon dioxide in the atmosphere are a major cause of climate change, and now a new study has confirmed that atmospheric CO2 is also affecting the ocean chemistry and potentially harming sea life.
Montana State University scientist Robert Dore has been researching the water in the Pacific Ocean for almost two decades.
"We"ve been going to the same spot in the Pacific Ocean, and we try and characterize long-term change in the open ocean environment. And one of the key things that we measure is CO2 levels. And we"ve been able to record this increasing quantity of atmospheric CO2 into the ocean."
Scientists expected that as atmospheric CO2 increased, more and more of the carbon dioxide would be absorbed into the ocean, affecting the chemical balance of the sea water, with a potentially harmful impact on shellfish and coral in particular.
"As carbon dioxide dissolves（溶解） in the water, or seawater in this case, it forms a weak acid, carbonic acid," Dore explains. "And therefore, as the concentration of CO2 in the atmosphere goes up and that exchanges with the surface seawater, it drives the pH down, and makes it more acidic."
The seawater Dore and his colleagues have analyzed confirms what the theory predicts.
The effect was particular striking at about 250 meters down, and again at 500 meters. Dore and his colleagues came up with two possible explanations. It could be that surface water picked up CO2 and then moved to those depths. Or there could be a biological explanation.
"It"s important to realize that the oceans are really becoming acidic. And it can have negative impacts on a whole variety of sea life from fish to coral. It"s potentially catastrophic."
53．What can be the best title of the passage?
A．Sea Life Facing Danger B．Climate Change Affecting Seawater
C．Oceans Becoming More Acidic D．Scientist Researching Seawater
54．Which of the following shows the process of the impact of atmospheric CO2 on sea life?
a．Sea life is endangered．
b．CO2 goes into the surface water．
c．The ocean chemistry is affected．
d．CO2decreases the PH and makes the seawater more acidic．

e．CO2 levels in the atmosphere go up．
55．Scientist Robert Dore came to the conclusion based on__________.
A．his research and analysis
B．a major cause of climate change
C．some former theory
D．the expectation of other scientists
56．What does the passage want to tell us most?
A．It takes time to make a scientific study．
B．Atmospheric CO2 is doing harm to sea life．
C．Robert Dore is a committed and serious scientist．
D．Measures should be taken to prevent the potential catastrophe．

"Depend on yourself" is what nature says to every man. Parents can help you. Teachers can help you. But all these only help you to help yourself.
There have been many men in history. But many of them were very poor in childhood, and no uncles, aunts or friends to help them. Schools were few. They could not depend upon them for an education. They saw how it was and set to work with all their strength to know something. They worked their own way till they became well-known.
One of the most famous teachers in England used to tell his pupils, "I can not make worthy men of you, but I can help make men of yourself."
Some young men don"t try their best to make themselves valuable to the human beings. They can never gain achievement(成就) unless they see their weak points and change their course. They are nothing now, and will be nothing as long as they live, unless they accept the advice of their parents and teachers, and depend on their own efforts.

阅读下列短文，从每题所给的A、B、C、D中，选出最佳选项，并在答题卡上将该项涂黑。
Learning new words is learning new ideas: High school students can take control of their
learning by always looking up new words and finding out what they mean. They should keep a dictionary and a thesaurus close at hand.
Make clear lists: Students should make a list of everything that they need to get done. They should check off assignments （作业）once completed. They should include clear due dates.
Make a commitment: Active learners will resolve to keep up –to-date from the start. They will avoid procrastinating (delay doing something). They will complete most of their work as early as possible.
Independent work is best: Students will so all assignments independently—they will never copy! Students who copy are passive learners. Passive learners do not give their mind a chance to think on its own.
Organization is key: Students should keep an excellent folder and notebook. All problems should be clearly stated and solutions given. All tests and quizzes should be corrected and used as study guides for exams and finals.
All actions without solutions are dead: Active learners will always show their work needed to solve a problem. Active learners will never turn in a list of answers without giving an explanation or a solution.
Advanced reading: Students should do any required reading for the topic before class. They should write an outline of the section or chapter. They should actively take notes as they read to help them remember.
