Many people consider their pets members of the family and are very sad when they die, but what if you could clone your dog, cat or bird?
A scientist in New Orleans, who has proved his ability to clone other animals, is now offering the possibility to pet owners here in Wisconsin．
Scientists have not been able to clone dogs, cats or other pets, but if and when the time comes, several companies will be ready and able to do the job．
The question is: Are you ready to clone your pet? Brett Reggio is betting on it．He is working on his Ph. D at Louisian State University. He's successfully cloned a goat five times and wants to try the process on family pets． So he started a business called Lazaron． “What Lazaron provides is the first step in the cloning process． ”He said．“It’s for curing and storing the fiberglass cells that will be used for cloning．”
“Your first reaction is yeah! I think I’d like that．” said Donna Schacht, a pet owner．
“I don’t believe you can ever replace a special love,” pet owner Paulette Callattion said．
Most pet owners will tell you freezing your pet’s DNA in hopes of one day cloning it is a personal decision．
Scientists say that cloning your own pet doesn’t mean that the offspring（后代） will have the same intelligence, temperament（性情） or other qualities that your pet has．From the passage we know that scientists have ______．
| A．tried to clone animals |
| B．cloned many kinds of animals |

Women with an hour glass figure have brains to go with their curves(曲线)，scientists claim.
Going in at the waist is said to be a sign of intelligence which leads to brighter children, too,Wonmen such as Nigella Lawson with a big difference between thir waist and hip measurements scored significantly better in tests than those with thinner,straighter frames,, Researchers concluded that it was not necessary for a woman to be skinny-what mattered was that her waist should be smaller than her hips, A ratio of 3:5 was found to be idea,
The study ,
by the Universities of Pittsdburgh and California,involved 16,000 women and girls,
According to the scientists，the results are no mere quirk of nature．They claim that the fat
Around culvy hips and thighs(大腿)holds higher levels of-3 fatty acids which are essential for
the growth of the brain during pregnancy．The fat which collects around the waist，howover．is
more likely to contain-6 fatty acids，which areless suited to brain growth．
Reporting in the joumal Evolution and Human Behaviour，the researchers found that the children of curvy mothers are more likely to do well in cognitive tests than others．they claim that this could help explain why the children of teenage mothers．who might not yet be physically mature enough to have developed real curves-tend to do less well in school．
As wel las boosting(提升)brainpower,一3 fatty acids found in oily fish arc considered to be of huge health benefit Although the study analysed women’s bodies only,一3 fatty acids are also stored in men’s hips ,However it is not known whether men with wide hips benefit from the same brain power boost,．

Federal regulators Wednesday approved a plan to create a nationwide emergnecy alert(警报) System using text messages delivered to cell phones.
Text messages have exploded in popularity in recent years, particularly among young people, The wireless industry’s trade association, CTIA, estimates(估计)more than 48 billion text messages are sent each month,
The plan comes from the Warning Alert and Response Network Act,a 2006 federal law that requires improvement to the nation’s emergency alert system. The act tasked the Fedral Communications Conmmissino(FCC)with coming up with new ways to alert the public about emergencies ．
“The ability to deliver accurate and timely warnings and alerts through cell phones and other mobile services is an improtant next step in our offorts to help ensure that the American public has the information they need to take action to protect themselves and their families before, and during, disasters and other emergencies.” FCC Chairman Kevin Martin said following approval of the plan,
Participation in the alert system by carriers-telecommunications companies-is voluntary, but it has received solid support from the wireless industry,
The program would be optional for cell phone users, They also may not be charged for receiving alerts.
There would be three different types of messages, according to the rules.
The first would be a national alert from the president ,likely involving a terrorist attack or natural disaster, The second would involve “approaching threats.” Which could include natural disasters like hurricanes or storms or even university shootings, The third would be reserved for child abduction(绑架)emergencies,or so –called Amber Alerts,
The service could be in place by 2010
68．What is the purpose of the approved plan?
A．To warn people of emergencies via messages．
B．To popularize the use of cell phones．
C. To estimate the monthly number of messages．
D. To promote the wireless industry．

What question do I have about this topic?
A great science project always includes an experiment．Make sure that your question can be
answered through an experiment．Here are some examples of questions：Does the amount of light have an effect on how fast plants grow？How much salt is in different kinds of cookies sold at the store? Why does the sky change color at different times of the day?
How much time do I have before the scienc fair?
A great science project always includes an experiment. Make sure that your question can be answered throuth an experiment, Here some examples of questions,Does the amount of light have an effect on how fast plants grow? How much salt is in different kinds of cookies sold at the store? Why does the sky change color at different times of the day?
How much time do I have before the science fair?
A science fair to be held in two weeks will not give you time for some experiments ,such as growing plants, carefully plan your project so that you allow enough time to perform your experiment accrately.
What do I think is the answer to my question?
Why do I think this? The answer you choose is your hypothesis,You will prove it right or wrong by perfoming an experiment,. If you were to think about the sky question, your hypothesis might be that the color of the sky is related to the position of the
sun,
How can I prove my hypothesis?
This is where the experiment comes in．You have to test your hypothesis．If you wanted to find out how light affects plant growth，you could plant seeds in a number of containers．Then you could expose the plants to different amotmts of light and compare the growth rates．
How can I present my results?
You might display your question and hypothesis on poster boards．You might then add pictures and graphs．A great science project also states a conclusion．A conclusion of the plant experiment might be The plants that got the most light grew the fastest．
When you have finished your project，you may have more questions．A great science project makes you want to learn even more．
