The Food and Drug Administration (FDA) is expected to rule soon that milk from cloned animals and meat from their offspring (后代) are safe to eat.

The agricultural industry has observed a self-acting stop on using the products of clones, but it has recently become clear that a few offspring of cloned pigs and cows are already flowing into the food supply. Many in agriculture believe such genetic copies are the next logical step in improving the nation’s livestock (家畜).

Many Americans are likely to be against the idea of serving clones’ milk to their children or putting meat from the offspring of clones into the kitchens. When they were asked earlier this year in a survey by the International Food Information Council whether they would willingly buy meat, milk and eggs that come from clones if the FDA declared them to be safe, 63 percent of consumers said no.

Yet scientific evidence suggests there is little cause for alarm, at least on food-safety grounds. Studies have shown that meat and milk from clones are not different from that from normal animals, although work is not complete and researchers say that clones do suffer slight genetic abnormalities (反常).

While milk from clones might reach the shelves, clones themselves are not likely to be eaten, since they cost thousands of dollars to produce. They’d be used as breeding stock(培育家畜), so the real question is whether their produced offspring would be safe.

The FDA has been promising a policy for three years, but hasn’t produced a final view, and some biotechnology companies involved in cloning have run out of cash while waiting. Livestock producers have called the FDA the“Foot Dragging Administration”.

Sure, it’s good to get along with your teacher because it makes the time you spend in the classroom more pleasant.

    And yes, it’s good to get along with your teacher because, in general, it’s smart to learn how to relate to (理解)the different types of people you’ll meet throughout your life.

    But really, there’s one super-important reason why you should get along with your teacher. When you do, “learning bursts right open,” says Evelyn Vuko, a longtime teacher who writes an education column（专栏） called “Teacher Says” for the Washington Post newspaper.

In fact, kids who get along with their teachers not only learn more, but they’re more comfortable asking questions and getting extra help. This makes it easier to understand new material and do your best on tests. When you have this kind of relationship with a teacher, he or she can be someone to turn to with problems, such as problems with learning or school issues, such as bullying(欺负人). 

As a kid in a primary or middle school, you’re at a wonderful stage in your life. You’re like a sponge(海绵), able to soak up lots of new and exciting information. On top of that, you’re able to think about all this information in new ways. Your teacher knows that, and in most cases, is very excited to be the person who’s giving you all that material and helping you put it together. Remember, teachers are people, too, and they feel great if you’re open to what they’re teaching you. That’s why they wanted to be teachers in the first place --- to teach!

Some kids may be able to learn in any situation, whether they like the teacher or not. But most kids are sensitive to the way they get along with the teacher, and if things aren’t going well, they won’t learn as well and won’t enjoy being in class.

You can't escape the message that smoking is bad for you.But what if one or both of your parents smoke?You might be worried about their health,sick of smelling the smoke,or even a little embarrassed(尴尬的) by it.You can't order your mom or dad to stop smoking ,but you can encourage them to quit.There are lots of good reasons.Here are some you can mention:

*Smoking will hurt their health.

*Smoking creates secondhand smoke,which you don't like .

*Smoking will make it hard for them to keep up with you because they might run out of breath easily.

If you think it will help,you could print out articles like this one to give it to your mom or dad. But what if your parent gets angry with you for bringing up the topic of smoking?People don't like to be reminded that they are doing something unhealthy,so it's possible that your parents will be insulted or angry,especially if they're worried they won't be able to quit.Maybe they have tried before and failed.

Remember to be kind and respectful when you discuss smoking with your mom or dad. Also rememeber that it is difficult to quit.Some people try several times before they're able to quit for good. Instead of yelling at the them,tell them that you love them and want them to enjoy many healthy years ahead. In time,your mom or dad may realize you are right about smoking .And if they do agree to stop smoking,be their biggest supporter.Ask if there's anything you can do to help them when they feel the urge to smoke.Maybe you could go for a walk,do a puzzle,or listen to music together.As they reach milestones,such as a month without smoking,be sure to celebrate the achievement.Way to go,mom!Way to go,dad!
