The United States government wants to know what the public thinks about its findings on the safety of cloned animals．
The Food and Drug Administration says meat and milk from clones of adult cattle, pigs and goats are safe to eat．An FDA official called them “as safe to eat as the food we eat every day．” And when those clones reproduce sexually, the agency says, their offspring(后代)are safe to eat as well．But research on cloned sheep is limited．So the FDA proposes that sheep clones not be used for human food．
The United States this year could become the first country to agree to the sale of foods from cloned animals．First, however, the public will have ninety days to comment on three suggested documents．On December 28th the FDA released a long report, called a draft risk assessment, along with two policy documents．
The agency says it must receive comments by April second．The FDA seemed ready to act several years ago, but a committee called for more research．
For now, the government will continue to ask producers to honor a request that they not sell foods from cloned animals．
Clones are still rare．They cost a lot and are difficult to produce．
The FDA says most food from cloning is expected to come not from clones themselves, but from their sexually reproduced offspring．It says clones are expected to be used mostly as breeding animals to spread good qualities．
Public opinion studies show most Americans do not like the idea of food from cloned animals．But this research also shows the public knows little about cloning．
Cloning differs from genetic engineering．A cell taken from a so-called donor animal is grown into an embryo(胚胎)in the laboratory．Next, the embryo is placed into the uterus(子宫)of a female animal．If the process is successful, the pregnancy reaches full term and a genetic copy of the donor animal is born．

Dahlia was running around the house screaming and crying．“I hate her! I hate her! I will 1 play with her again!” Finally, her steps slowed． 2 she told her father what had happened．He listened attentively． 3 she stopped, he asked, “Is there 4 else?” Dahlia added more details and began 5 bitterly again．Father listened．When Dahlia 6 talking, he said, “It must 7 to be made fun of like this by your best friend Tina．” Dahlia 8 her father embraced(拥抱)and support as she cried 9 more in his arms．Then as 10 as the storm of tears began, she was finished．She got up and 11 announced, “Daddy, did you know that tomorrow Tina and I are going together to the beach? We are 12 a log house there with Adam and Tom, I will tell Tina before we go that I 13 ruin her work again, and I'm sure she will be 14 to me．”
Why was this encounter(sudden meeting)so successful? How did Dahlia 15 her upset so completely and realize her responsibility in the matter 16 her own?
There were three main parts in her father's reaction that 17 ：(A)Attention(B)Respect(C)Trust．He gave his daughter 18 attention and took her seriously as she 19 her feelings．He respected her by not coming with words of wisdom, advice or help．He validated(证实)the feeling she 20 ．And he trusted her to do and say what she needed in order to lead herself toward resolution of her emotions．
A high school history teacher once told us, “If you make one close fried in school, you will be most fortunate．A true friend is someone who stays with you for life．” 1 teaches that he is right．Good friendship is just not easily 2 ．
It is possible that we simply do not stay in one place long enough for a true friendship to 3 ．However, there can be 4 disagreement in the need for each of us to think carefully about what kind of friendship we want．
To most of us, 5 are considered very important, but we need to make it clear in our minds what kind of friendship we want．Are they to be close or 6 at arm’s length? Do we want to 7 ourselves or do we want to walk on surface? For some people, many friendships on the surface are 8 enough and that’s all right．But at some point we need to make sure that our 9 are the same as our friends’ expectations．The sharing of 10 experiences including our tears as well as our dark dreams is the surest way to 11 friendships．But it must be undertaken(进行)slowly and 12 only if there are signs of interest and action 13 ．
What are some of the 14 of friendship? The greatest is the attraction to expect too much too soon．Deep relationships 15 time．Another “major difficulty” is the selfishness to think one “ 16 ” the other, including his time and attention． 17 , friendships require actions in return．In other words, you must give as 18 as you take．Finally, there is a question of taking care of．Unless you spend 19 time together, talking on the phone, writing letters, doing things together, friendships will die 20 ．
