Air Pollution Cloud Measured on Both Sides of Pacific
Scientists watched closely last spring as a haze of pollution, which had been tracked by satellite as it crossed the Pacific Ocean，settled over a large swath of North America from Calgary, Canada，into Arizona．Now it appears that，for the first time, researchers on both sides of the Pacific took detailed measurements of the same plume，a cloud that contained Gobi desert dust as well as hydrocarbons from industrial pollution．
Heather Price，a University of Washington doctoral student in chemistry, found that the amount of light reflected by the particles in the air was more than 550 percent greater than normal for that time of year．The mass of Asian air contained elevated levels of all pollutants measured．
Price said，“but the only thing that came close to being alarming was the level of particulate Matter.”
The haze that settled across the western part of the country was widely reported by the news media，and it was measured as far inland as the ski slopes of Aspen, Colo.
Readings on the western side of the Pacific came from the Aerosol Characterization Experiments, a project aimed at understanding how particles in the atmosphere affect Earth’s climate. Additional measurements were taken in the same region at the same time under a project sponsored by the National Aeronautics and Space Administration．
Knowing the pollution was approaching Washington state，Price loaded sensing equipment aboard a rented Beechcraft on April 1 4 and flew to Neah Bay on the state’s Northwest coast．Taking samples at various levels from 15，000 feet to 20，000 feet in altitude，she monitored
quantities of dust，ozone，carbon monoxide and hydrocarbons．“From my copilot’s seat．the dust
was thick enough to see with the naked eye．”Price said．
Now she’s trying to correlate her findings with those of the two research teams operating on the other side of the Pacific，where at one point the pollution plume was larger than Japan．The huge size of the cloud showed up clearly in satellite images that gave Price plenty of warning the haze was on its way．“You can see these two blobs coming out of the deserts of Mongolia and growing over Asia，then getting swept out over the ocean and finally setting over North America,”
she said. She intends to continue measuring air samples off the Washington coast and will be looking for air masses with evidence of pollution originating somewhere other than Asia. “We’d
like to see if we can get a signature of pollution coming from Europe because computer models suggest that European sources also can be transported across the Pacific，” she said．“However, we
expect that sources in Europe will contribute less than Asian sources．”

The first four minutes
When do people decide whether or not they want to become friends? During their first four minutes together, according to a book by Dr. Leonard Zunin. In his book, "Contact: The first four minutes," he offers this advice to anyone interested in starting new friendships: __1__. A lot of people’s whole lives would change if they did just that.
You may have noticed that average person does not give his undivided attention to someone he as just met.__2__. If anyone has ever done this to you, you probably did not like him very much.
When we are introduced to new people, the author suggests, we should try to appear friendly and self-confident. In general, he says, "People like people who like themselves."
On the other hand, we should not make the other person think we are too sure of ourselves. It is important to appear interested and sympathetic, realizing that the other person has his won needs, fears, and hopes.
Hearing such advice, one might say, "But I’m not a friendly, self-confident person. That’s not my nature. It would be dishonest for me to at that way."
__3__. We can become accustomed to any changes we choose to make in our personality. "It is like getting used to a new car. It may be unfamiliar at first, but it goes much better than the old one."
But isn’t it dishonest to give the appearance of friendly self-confidence when we don’t actually feel that way? Perhaps, but according to Dr. Zunin, "total honest" is not always good for social relationships, especially during the first few minutes of contact. There is a time for everything, and a certain amount of play-acting may be best for the first few minutes of contact with a stranger. That is not the time to complain about one’s health or to mention faults one finds in other people. It is not the time to tell the whole truth about one’s opinions and impressions.
__4__. For a husband and wife or a parent and child, problems often arise during their first four minutes together after they have been apart. Dr. Zunin suggests that these first few minutes together be treated with care. If there are unpleasant matters to be discussed, they should be dealt with later.
The author says that interpersonal relations should be taught as a required course in every school, along with reading, writing, and mathematics. __5__ that is at least as important as how much we know.
A. In reply, Dr. Zunin would claim that a little practice can help us feel comfortable about changing our social habits.
B. Much of what has been said about strangers also applies to relationships with family members and friends.
C. In his opinion, success in life depends mainly on how we get along with other people.
D. Every time you meet someone in a social situation, give him your undivided attention for four minutes.
E. He keeps looking over the other person’s shoulder, as if hoping to find someone more interesting in another part of the room.
F. He is eager to make friends with everyone.
