How to Do Man-on-the-Street Interviews

The man-on-the-street interview is an interview in which a reporter hits the streets with a cameraman to interview people on the sport. _____ But with these tips, your first man-on-the-street interview experience can be easy.

? When your boss or professor sends you out to do man-on-the-street interviews for a story, think about the topic and develop a list of about ten general questions relating to it. For example, if your topic is about environmental problems in America, you might ask, “Why do you think environmental protection is important in America?” _____

? Hit the streets with confidence. _____ Say, “Excuse me, I work for XYZ News, and I was wondering if you could share your opinion about this topic.” This is a quick way to get people to warm up to you.

Move on to the next person if someone tells you she is not inter

Don’t get discouraged.

Each interview that you get on the street shouldn’t be longer than ten minutes. As soon as you get the answer you need, move on to the next person. Make sure that as you go from interview to interview, you are getting a variety of answers. If everyone is giving you the same answer, you won’t be able to use it. A safe number of interviews to conduct is about six to ten.

● If your news station or school requires interviewees to sign release forms to appear on the air, don’t leave work without them.

A. Limit your time.

B. As you approach people, be polite.

C. If you don’t own a camera, you can buy one.

D. For new reporters, this can seem like a challenging task.

E. To get good and useful results, ask them the same question.

F. That number of interviews should give you all the answers you need.

G. With a question like this, you will get more than a “Yes” or “No” reply.

Before birth,babies can tell the difference between loud sounds and voices.They can even distinguish their mother’s voice from that of a female stranger.But when it comes to embryonic learning(胎教),birds could rule the roost.As recently reported in The Auk:Ornithological Advances,some mother birds may teach their young to sing even before they hatch(孵化).New-born chicks can then imitate their mom’s call within a few days of entering the world.

This educational method was first observed in 2012 by Sonia KIeindorfer,a biologist at Flinders University in South Australia,and her colleagues.Female Australian superb fairy wrens were found to repeat one sound over and over again while hatching their eggs,When the eggs were hatched,the baby birds made the similar chirp to their mothers—a sound that served as their regular “feed me!”call.

To find out if the special quality was more widespread in birds,the researchers sought the redbacked fairy wren,another species of Australian songbird.First they collected sound data from 67 nests in four sites in Queensland before and after hatching.Then they identified begging calls by analyzing the order and number of notes.A computer analysis blindly compared calls produced by mothers and chicks,ranking them by similarity.

It turns out that baby red-backed fairy wrens also emerge chirping like their moms. And the more frequently mothers had called to their eggs,the more similar were the babies’ begging calls. In addition,the team set up a separate experiment that suggested that the baby birds that most closely imitated their mom’s voice were rewarded with the most food.

This observation hints that effective embryonic learning could signal neurological(神经系统的)strengths of children to parents.An evolutionary inference can then be drawn.”As a parent,do you invest in quality children,or do you invest in children that are in need?”KIeindorfer asks.”Our results suggest that they might be going for quality.”

1.The underlined phrase in Paragraph 1 means“ ”.

A.be the worst B.be the best

C.be the as bad D.be just as good

2.What are Kleindorfer’s findings based on?

A.Similarities between the calls of moms and chicks.

B.The observation of fairy wrens across Australia.

C.The data collected from Queensland’s locals.

D.Controlled experiments on wrens and other birds.

3.Embryonic learning helps mother birds to identify the baby birds which .

A.can receive quality signals B.are in need of training

C.fit the environment better D.make the loudest call

Taking a math test can be pretty stressful. Even if you know the material, you can still get the problem wrong. 1. Therefore you’ll improve your grades, as well as your math skills.

Write it out

You can also check a math problem by writing everything out on paper. 2. Writing out math problems reduces your chances of missing anything to the lowest possible level, which is a common cause of incorrect answers.

3.

Make sure your answers work by doing the opposite procedure of what your problem calls for, including the answer you got the first time around. In other words, you would use the opposite of this addition problem—subtraction (减法)—to determine whether your answer is the correct one.

Plug in(代入)

You may find that a variable isn’t good enough or have a problem where you have to solve for a variable (变量). 4. This is the only real way to assure yourself that the answer you’ve found is correct.

5.

If the result of a problem seems to make no sense, it indicates that the answer is incorrect. For example, if you get an answer in the millions and you know it should be in the thousands, you’ve likely misplaced a point. Go back through the work on your paper to make sure all of your formulas and calculations are correct. If everything looks okay, do the problem again and compare the result of the second try to what you’ve got on the first try.

A. Do the opposite.

B. Correct the answers.

C. Plug the variable in the equation (方程) to check it out.

D. Knowing how to go through your math test and checking your work can save you from handing in a test full of mistakes.

E. It also helps you to figure out everything after you have already finished the test.

F. Check for a reasonable answer

G. This helps you to know what information you have and what information you need to solve.
