If you are invited to a wedding, baby shower or other celebrations, you will be expected to bring a gift. Unless you know the host very well, the gift should be modest in value, about $25 or so.

For a wedding ， the bride will have "registered ( 登 记 )" at one or two local department stores，indicating the items she prefers．You can buy the couple a gift that isn’t listed , but most people buy something listed on the registry (记录簿). If you buy an item listed on the registry, be sure to tell the store that you are doing this, so that the couple doesn’t receive duplicate (重复的) gifts．For a baby shower，bring a gift appropriate for a new born baby．

If you wish to give a gift when you leave to return to your country, the best gift     is something unique to your country. It does not need to be especially valuable or rare. Possibilities include a book about your country, an inexpensive piece of handicraft( 手工艺品)or art, or something else that reflects your culture. If the children collect coins and stamps, they would be very pleased with a set of your country’s coins or a selection of stamps from your country.

If you owe a debt of deep gratitude to an American host family, a common way of repaying it is to take the family to a form of entertainment, such as a baseball, basketball, or a good restaurant.

Gift giving is not as important in America as it is in other countries, so there is nothing wrong with not giving a gift. If you need help, talk to a salesperson at a department store. Tell them about the person who will be receiving the gift and the reason for the gift, and they will help you find something appropriate.

As early as 2005, there were a number of new stories about dog cloning(克隆) and cat cloning. Animal cloning had been old news for nearly a decade by then, with the revolutionary (革命的) cloning of Dolly the sheep in Scotland.

However, Snuppy was the first pet, a dog, to be cloned. Since the cloning of Snuppy, there has been some very successful cloning of pets and other animals. Lou Hawthorne started BioArts while cloning his beloved mixed-breed dog Missy. Hawthorne was very pleased with the results of the cloning, producing three successful clones that were very alike to the original in character and behavior. In January, 2009, a Florida couple, Ed and Nina Otto, announced that they had paid to have their dog cloned by BioArts.

All new technology is overpriced. For example, personal computers were not very affordable at first. Only after the producing process was improved was it   possible for every family to have a computer. How much room there will be for organizations to reduce the price point on pet cloning without broad demand is of course questionable.

There are many great dogs and cats that can be found at the local dog pound ( 野狗收容所) or are given away for “free to good homes” in classified ads (分类广告). However, there is no limit to the value people place on a beloved pet. The Ottos are a good example of that. If people can buy a dog or cat with predictable behavior and characteristics, there is value in that. There is a predictable market here, though it may always be limited in size.

While pet cloning has not taken off as some hoped, it’s clear that it will become   a bigger market in the future and it will be increasingly possible for people to try this out. With the inevitable (不可避免的) success that cloned pet owners will have, the practice will become more widely accepted and it seems inevitable that there is a future for cloned dogs and cats.

The first day my new teacher walked into our school in Spanish Harlem, I burst out laughing. Ron Clark was this young white guy from North Carolina who talked with a funny Southern accent（口音）. He said he used to be a singing waiter. I thought, Who is this guy? He's a complete joke.

It was 1999 and I was in the fifth grade at New York City's P.S. 83. I guessed I'd spend most of the year in the headmaster's office. I'd always been a troublemaker. I'd get shouted at, and then the teachers would give up on me. I thought that's what   would happen with Ron Clark.

I was wrong. That first week, I kept laughing at him. He pulled me out to the hallway and said I'd better shape up（表现好）. "Tamara," he said, "you're a smart kid. You can do better."

He told me I was a natural leader and that I'd go far in life if I started studying hard. I was mad at first, but then something happened: I began to respect him. There were 29 students in our class, and it didn't take long for us to realize that Ron Clark was no ordinary teacher.

Like most teachers, he had lots of rules: Treat each other like family. Don't cut in line. But the real difference was how concerned he was. Mr. Clark ate with us in the lunchroom instead of going to the teachers' day-room. At first, my friends and I were thinking, What is he doing?

He asked us what was going on in our lives. Between classes, he came outside with us, and we taught him how to jump rope. When it snowed, Mr. Clark, who'd never seen snow before, threw us with snowballs, and we threw him back.

Before coming to P.S. 83, he taught at Snowden Elementary in his hometown, Belhaven, North Carolina. His parents were DJs( 流行音乐节目主持人)at dance clubs, so he grew up with music and energy. He wanted a life of adventure, he told me, but his mom encouraged him to ask for a position at Snowden when one of the teachers passed away. Mr. Clark ended up loving it. He came to Harlem because he'd seen a TV show about our troubled schools and the lack of qualified teachers. He wanted a challenge. Boy, did he get one.
