     Many people have heard stories of the California gold rush during the 19th century, when lots of
people went there in search for gold. Panning (淘洗) for gold has a rich and interesting history.
Nowadays some people continue to pan for gold in California. Although it cannot be regarded as a
method for earning income, taking on gold-panning as a hobby can give you a feeling of being in the old
west and get you out into nature.
     The only tool that is required to pan for gold is a gold pan. You can use a regular old flat pan, but
"officially" gold pans are quite cheap so you may as well buy one that is made for the task. Most sold
pans come in either plastic or metal.
     Once you have your pan you will want to start practicing your gold panning technique. Panning for
gold works because gold is much heavier than most rocks. To pan for gold you add rock and dirt form
the bottom of a stream to your pan and then gently let water flow through the pan. The lighter-weight
rocks are slowly swept away while any gold will be left behind in the pan.To start panning for gold, first
you will need to find a good location. Try checking maps of your area and old history books to find
location where there were gold mines in the past. Even though most of the gold have already been
removed, there are likely to be small leftovers that you can find. Once you have found an area that looks
promising, look for any small stream or river where you can try out panning for gold.
     Panning for gold requires patience and it may be a long time before you hit anything of value. However, it is an enjoyable hobby and provides a great opportunity to get outdoors, so don't give up too quickly.
1. What is Paragraph 3 mainly about?
A. Where to pan for gold.

Every people has its own way of saying things, its own special expressions. Many everyday American expressions are on colors.

Red is a hot color. Americans often use it to express heat. They may say they are red hot about something unfair. When they are red hot they are very angry about something. The small hot tasting peppers found in many Mexican foods are called red hots for their color and their fiery taste. Fast loud music is popular with many people. They may say the music is red hot, especially the kind called Dixieland jazz.

Pink is a lighter kind of red. People sometimes say they are in the pick when they are in good health. The expression was first used in America at the beginning of the twentieth century. It probably comes from the fact that many babies are born with a nice pink color that shows that they are in good health.

Blue is a cool color. The traditional blues music in the United States is the opposite of red hot music. Blues is slow, sad and soulful. Duke Ellington and his orchestra recorded a famous song – Mood Indigo – about the deep blue color, indigo. In the words of the song: “You ain’t been blue till you’ve had that Mood Indigo.” Someone who is blue is very sad.

The color green is natural for trees and grass. But it is an unnatural color for humans. A person who has a sick feeling stomach may say she feels a little green. A passenger on a boat who is feeling very sick from high waves may look very green.

Sometimes a person may be upset because he does not have something as nice as a friend has, like a fast new car. That person may say he is green with envy. Some people are green with envy because a friend has more dollars or greenbacks. Dollars are called greenbacks because that is the color of the back side of the paper money.

The color black is used often in expressions. People describe a day in which everything goes wrong as a black day. The date of a major tragedy is remembered as a black day. A blacklist is illegal now. But at one time, some businesses refused to employ people who were on a blacklist for belonging to unpopular organizations.

If you had your wallet stolen while doing some shopping, you may call it        .

A.a white day      B.a black day      C.a red day  D.a green day

ARLANDA, Sweden (Reuters Life!)—Many people hate the idea of having to sleep on a plane. But Swedish entrepreneur Oscar Dios thinks they can be persuaded otherwise and he has created a new kind of hostel to prove it.

Dios says it is the world’s first jumbo (unusually large) jet hostel, an actual jet-plane at Sweden’s main airport outside Stockholm which has been changed into a 25- room guesthouse that sleeps as many as 72 people.

“I learned about this plane that was standing deserted at Arlanda airport and I’ve been trying the concept of hostels in many different houses and buildings,” he told Reuters. “I thought, ‘Why not a plane?’”

Jumbo Hostels opened for business on Thursday, giving customers the chance to check in and sleep in a room that can best be described as comfortable.”

“The most challenging part with this project is trying to build something inside a metal hull(壳) – it’s just really, really tight.”

The jet, which was originally produced for Singapore Airlines, was taken out of service in 2002. It is held on a concrete foundation with the landing gear secured in steel cradles.

One feature of the hostel is its price – a room starts at 350 Swedish crowns (about $ 41), which is a lot less than hotel rooms outside of major airports.

Another feature is that customers can get married on the wing of the plane and stay in the plane’s more luxurious honeymoon suite (套房).

Instead of walking down the aisle in the church, lovebirds can take what Jumbo Hostels calls the “wing walk,” where they can be joined in great happiness at the wing tip. The hostel has someone ready to perform the ceremony.

But in some respects this hostel remains a plane – most customers have to share the jet’s nine bathrooms and the staff only wear air host and hostess outfits. The only room that has its own bathroom is the honeymoon suite.

Which of the following is not true?

A. The jet plane was out of use for over eight years

B. The hostel provides ten bathrooms for customers

C. The rooms in the hotel are comfortable

D. The hostel lies at Arlanda airport in Stockholm

One of the features of the plane hostel is that         .

A. air hostesses can offer good service

B. a wedding ceremony can be held on the wing    

C. customers can sleep in comfortable rooms      

D. the staff can have a “wing walk”

Why does Oscar Dios make jet plane hotel?

A. Because he is fond of plane very much.

B. Because he is very curious

C. Because he wants to earn more money.

D. Because he likes trying the concept of hotel in many different things.

The writer mainly wants to          .

A. call on people to make use of the deserted things

B. describe a wonderful place for weddings

C. introduce a new kind of hostel    

D. prove people can sleep on a plane

Thirty- two people watched Kitty Genovese being killed right below their windows. She was their neighbor. Yet none of the 32 helped her. Not one even called the police. Was this in gunman cruelty? Was it lack of feeling about one’s fellowman?

  “Not so,”say scientists John Barley and Bib Fatane. These men went beyond the headlines to research into the reasons why people didn’t act. They found that a person has to go through two steps before he can help. First he has to notice that is an emergency(紧急情况). Suppose you see a middle-aged man fall to the side - walk. Is he having a heart attack? Is he in a coma(昏迷) from a headache? Or is he about to sleep off a drunk? Is the smoke coming into the room from a leak(漏洞)in the air conditioning? Is it “steam pipes”? Or is it really smoke from a fire? It’s not always easy to tell if you are faced with a real emergency. Second, and more important, the person faced with an emergency must feel personally responsible(负责任的). He must feel that he must help, or the person won’t get the help he needs.

  The researchers found that a lot depends on how many people are around. They had college students in to be “tested.”Some came alone. Some came with one or two others. And some came in large groups. The researchers started them off on the “tests.”Then they went into the next room. A curtain divided the “testing room”and the room into which they went. Soon the students heard a scream, the noise of bookshelves falling and a cry for help. All of this had been prerecorded on a tape recorder.

  Eight out of ten of the students taking the test alone acted to help. Of the students in pairs, only two out of ten helped. Of the students in groups, none helped.

  In other words, in a group, Americans often fail to act. They feel that others will act. They, themselves, needn’t. They do not feel any direct responsibility.

  Are people bothered by situations where people are in trouble? Yes. Scientists found that the people were shocked, they sweated, and they had trembling hands. They felt the other person’s trouble. But they did not act. They were in a group. Their actions were shaped by the actions of those they were with.

60. The purpose of this passage is ________.

 A. to explain why people fail to act in emergencies

 B. to explain when people will act in emergencies

 C. to explain what people will do in emergencies

D. to explain how people feel in emergencies

61. Which of the following is NOT true?

  A. When a person tries to help others, he must be clear that there is a real emergency.

  B. When a person tries to help others, he should know whether they are worth his help.

  C. A person must take the full responsibility for the safety of those in emergencies if he wants to help.

  D. A person with a heart attack needs the most.

62. The main reason why people fail to act when they stay together is that ________.

  A. they are afraid of emergencies

  B. they are not willing to get themselves involved

  C. others will act if they themselves hesitate

D. they do not have any direct responsibility for those who need help

63. The author suggests that ________.

  A. we shouldn’t blame a person if he fails to act in emergencies

  B. a person must feel guilty if he fails to help

  C. people should be responsible for themselves in emergencies

D. when you are in trouble, people will help you anyway
