A.　 Join a Class, Sports Team, or Club

　　　 B.　 Eat alone in Public

　　　 C. Talk to your Neighbors

　　　 D.　 Keep an Open Mind

　　　 E.　 Take Pictures

　　　 F.　 Meet People through your Job

　　　 What could seem like an exciting, fresh new start can also be a huge pain: moving to a new city. Whether you decided to pick up and go because of a job offer, or simply wanted to get away from your old town, moving to a brand new city allows for a chance to start a new----brand new image and all.

　　　 But the big move can also be terrible; especially if you don’t know anyone in the place you now call home.

　　　 So in order to create your new image, you’ll need a whole new crew. Here’s how to meet some of those new people.

61. _____________

One of the great things about taking pictures at an event or party is that it gives you an excuse to get in touch with the person later. Everybody loves seeing pictures of himself, and it’s very easy after taking a picture to say “Are you on Facebook?” or “If you’d like I can email it to you.”

This can be the seed that leads to new connections. The next time you hear about a fun event email your new contacts to let them know about it.

62. _____________

　　　 If you don’t know anyone in a new city, it can be tempting to order take-out and retreat back to your lonely apartment or hotel room. Instead, try eating by yourself in public as often as possible.

You might feel self-conscious eating by yourself but it has an important benefit: you are much easier to approach when you are alone. People may be afraid of interrupting you or being rude if you are in a conversation with someone else.

Bring a book or newspaper to read (this will make you feel less self conscious). Plus, having an interesting book with you will give others an excuse to start a conversation if they’ve read it.

63. _____________

　　　 Yoga, salsa dancing, volleyball, jogging, Toastmasters (a Public Speaking club), a class for work, martial arts, etc. Take up a new hobby or continue an old one!

These are all great places to meet new people, primarily because you will be forced to see the same people over and over again in the class. You will automatically make friends with them if you have a common interest and are forced to see each other again.

64. _____________

　　　 You’re most likely to meet people at your office, so make sure to chat with the guy who sits at the cubicle next to yours, and try to make casual conversation with everyone from your manager to the guy who fixes the photocopy machine. This is your chance to spread yourself thick and make that extra effort, since you’re still considered “the new guy” and will be getting a certain degree of attention. Use it to your advantage.

　　　 Try to eat at the cafeteria rather than at your desk, and take people up on their offer to join them for lunch or go to the local happy tour; even if some of these people aren’t exactly “your type”, they might have friends that you’d love to hang with.

65. _____________

　　　 You may have never even known your previous neighbors, but home is a great place to start meeting people. There could be a whole pool of cool people in your apartment building or on your street, especially if you’re in the right area. So when you see some one from your apartment building getting their mail or a guy washing his car in his driveway, break the ice by asking a question that shows you’re new in town, like where the local video of liquor store is, and where the hot clubs are. Never overlook those that live next door, as they can always come in handy when you need them.

Lead deposits, which accumulated in soil and snow during the 1960’s and 70’s, were primarily the result of leaded gasoline emissions originating in the United States. In the twenty years that the Clean Air Act has mandated unleaded gas use in the United States, the lead accumulation worldwide has decreased significantly.

A study published recently in the journal Nature shows that air-borne leaded gas emissions from the United States were the leading contributor to the high concentration of lead in the snow in Greenland. The new study is a result of the continued research led by Dr. Charles Boutron, an expert on the impact of heavy metals on the environment at the National Center for Scientific Research in France. A study by Dr. Boutron published in 1991 showed that lead levels in arctic snow were declining.

In his new study, Dr. Boutron found the ratios of the different forms of lead in the leaded gasoline used in the United States were different from the ratios of European, Asian and Canadian gasolines and thus enabled scientists to differentiate (区分) the lead sources. The dominant lead ratio found in Greenland snow matched that found in gasoline from the United States.

In a study published in the journal Ambio, scientists found that lead levels in soil in the Northeastern United States had decreased markedly since the introduction of unleaded gasoline.

Many scientists had believed that the lead would stay in soil and snow for a longer period.

The authors of the Ambio study examined samples of the upper layers of soil taken from the same sites of 30 forest floors in New England, New York and Pennsylvania in 1980 and in 1990. The forest environment processed and redistributed the lead faster than the scientists had expected.

Scientists say both studies demonstrate that certain parts of the ecosystem respond rapidly to reductions in atmospheric pollution, but that these findings should not be used as a license to pollute.

59.　 How did scientists discover the source of lead pollution in Greenland?

A.　 By analyzing the data published in journals like Nature and Ambio.

B.　 By observing the lead accumulations in different parts of the arctic area..

C.　 By studying the chemical elements of soil and snow in Northeastern America.

D.　 By comparing the chemical compositions of leaded gasoline used in various countries.

60.　 The authors of the Ambio study have found that ________.

A.　 forests get rid of lead pollution faster than expected

B.　 lead accumulations in forests are more difficult to deal with

C.　 lead deposits are widely distributed in the forests of the US

D.　 the upper layers of soil in forests are easily polluted by lead emissions
