trouble speaking, and other problems. Some people also have a decrease in mental skills ( dementia).
4 At this time, there is no cure for Parkinson’s disease. But there are several types of medicines that can control the symptoms and make the disease easier to live with. You may not even need treatment if your symptoms are mild. Your doctor may wait to prescribe medicines unntil your symptoms start to get in the way of your daily life. Your doctor will adjust your medicines as your symptoms get worse. You may need to take several medicines to get the best results.

Martin Luther King Jr.
By the time the Montgomery Improvement Association chose the 26-year-old Martin Luther King Jr. as its leader, the hours-old bus boycott by the black citizens of Montgomery, Alabama, was already an overwhelming success. King would later write that his unanticipated call to leadership \through.\nomination.\
Although press reports at the time focused on his inspiring oratory,

King was actually a reluctant leader of a movement initiated by
others.(The boycott began on Dec. 5 1955.) His subsequent writings and private correspondence reveal man whose inner doubts sharply contrast with his public persona. In the early days of his involvement, King was troubled by telephone threats, discord within the black community and Montgomery's \tough\policy, to which king attributed his jailing on a minor traffic violation. One night, as he considered ways to \of the picture without appearing a coward,\at that moment, \experienced Him before.\
He would later admit that when the boycott began, he was not yet firmly committed to Gandhian principles. Although he had been exposed to those teachings in college, he had remained skeptical. \thought the only way we could solve our problem of segregation was an armed revolt,\he recalled. \relationships.\
Only after his home was bombed in late January did king reconsider his views on violence. (At the time, he was seeking a gun permit and was protected by armed bodyguards.) Competing with each other to influence King were two ardent pacifists: Bayard Rustin, a black activist with the War Resisters League, and the Rev. Glenn E. Smiley, a white staff member of the Fellowship of Reconciliation. Rustin was shocked to discover a gun in King's house, while Smiley informed fellow pacifists that King's home was \
31. What did King think of his nomination as leader of the Montgomery Boycott?
A) He hadn't expected it.
B) He had to think about it carefully. C) He would refuse to accept it. D) He was prepared to accept it.
32. Why was King unwilling to lead the movement at first? A) Because he doubted if the boycott would be successful.
B) Because he was troubled with a traffic accident at that time. C) Because he thought he was too young to be a leader. D) Because he himself didn't start the boycott. 33. Which of the following is Not mentioned as something that happened at the beginning of the black people's movement?
A) King was put into prison.
B) Black people disagreed with each other.
C) King's armed revolt proposal was turned down.
D) Black people found it hard to accept the policy pursued in Montgomery.
34. Which of the following was the immediate cause that made King change his view on violence?

B) The attack of his home.
C) The influence of two active non-violence advocates. D) The verdict of the Supreme Court.

A) King's home was a place where people got together. A Phone That Knows You're Busy
It's a modem problem: you're too busy to be disturbed by incessant (连续不断的) phone calls so you turn your cell phone off.But if you don't remember to turn it back on when you're less busy. You could miss some important calls if only the phone knew when it was wise to interrupt you, you wouldn't have to turn it off at all. Instead, it could let calls through when you are not too busy.
A bunch of behavior sensors (传感器) and a clever piece of software could do just that, by analyzing your behavior to determine if it's a good time to interrupt you. If built into a phone, the system may decide you're too busy and ask the caller to leave a message or ring back later.
James Fogarty and Scott Hudson at Camegie Mellon University in Pennsylvania based their system oil tiny microphones, cameras and touch sensors that reveal body language and activity. First they had to study different behaviors to find out which ones strongly predict whether your mind is interrupted.
The potential \signals they focused on included whether the office doors were left open or closed, the time of day, if other people were with the person in question, how close they were to each other, and whether or not the computer was in use.
The sensors monitored these and many other factors while four subjects were at work. At random intervals, the subjects rated how interruptible they were on a scale ranging from \not-interruptible\behaviors . \is a shotgun (随意的) approach: we used all the indicators we could think of and then let statistics find out which were important, \
The model showed that using the keyboard, and talking on a landline or to someone else in the office correlated most strongly with how interruptible the subjects judged themselves to be. Interestingly, the computer was actually better than people at predicting when someone was too busy to be interrupted.The computer got it right 82 per cent of the time, humans 77 per cent. Fogarty speculates that this might be because people doing the interrupting are inevitably biased towards delivering their message, whereas computers don't care.
The first application for Hudson and Fogarty's system is likely to be in an instant messaging system, followed by office phones and

Effects of Environmental Pollution
If pollution continues to increase at the present rate, formation of aerosols (浮质) in the atmosphere will cause the onset (开始) of an ice age in about fifty years' time. This conclusion, reached by Dr. S.I. Rasool and Dr. S.H. Schneider of the United States Goddard Space Flight Centre, answers the apparently conflicting questions of whether an increase in the carbon dioxide (二氧化碳) content of the atmosphere will cause the Earth to warm up or increasing the aerosol content will cause it to cool down. The Americans have shown conclusively that the aerosol question is dominant.
Two specters haunting conservationists have been the prospect that environmental pollution might lead to the planet's becoming unbearably hot or cold.One of these ghosts has now been laid.Because it seems that even an increase in the amount of carbon dioxide in the atmosphere to eight

times its present value will produce an increase in temperature of only
2 ℃, which would take place over several thousand years. But the other problem now looms larger than ever.
Aerosols are collections of small liquid or solid particles dispersed in air or some other medium. The particles are all so tiny that each is composed of only a few hundred atoms. Because of this they can float in the air for a very long time. Perhaps the most commonly experienced aerosol is industrial smog (烟雾) of the kind that plagued London in the 1950s and is an even greater problem in Los Angeles today. These collections of aerosols reflect the Sun's heat and thereby cause the Earth to cool.
Dr. Rasool and Dr. Schneider have calculated the exact effect of a dust aerosol layer just above the Earth's surface in the temperature of the planet. As the layer builds up, the present delicate balance between the amount of heat absorbed from the Sun and the amount radiated from the Earth is disturbed.The aerosol layer not only reflects much of the Sun's light but also transmits the infrared (红外线的 ) radiation from below. So, while the heat input to the surface drops, the loss of heat remains high until the planet cools to a new balanced state.
Within fifty years, if no steps are taken to stop the spread of aerosols in the atmosphere, a cooling of the Earth by as much as 3.5~C seems inevitable.If that lasts for only a few years it would start another ice age, and because the growing ice caps at each pole would themselves reflect much of the Sun's radiation it would probably continue to develop even if the aerosol layer were destroyed.
The only bright spot in this gloomy forecast lies in the hope expressed by Dr. Rasool and Dr. Schneider that nuclear power may replace fossil fuels in time to prevent the aerosol content of the atmosphere from becoming critical.
