One day before Christmas, all of us children from the Children's Home Society Orphanage(孤儿院) were taken to the Mayflower Hotel in downtown to attend a Christmas party.
After the man on the stage said a prayer(祈祷), we were told to1 . Within minutes we were 2a meal which was fit for a king. I ate 3I could eat no more. As we ate, Santa Clause came walking out onto the4. The kids cheered with5. Everyone began clapping their hands and yelling as6as they could.
I too was excited7but I knew better than to yell(叫喊)out loud or to jump up and scream. Mrs. Winters, the head matron, sat only three seats from me. She had8it very clear to everyone that we were tobehaveourselves in "a proper manner" and that there was to be "no yelling or shouting".
One orphan9was led up onto the stage and each kid was handed a10by Santa Claus himself.
As the line became shorter and shorter my11finally came. He smiled at me. Then he reached over and handed me a12box which had two gold ribbons(丝带) on it. As I leaned(向前倾) to take the box I tripped and I13to my knees. Santa reached over and helped me to my feet.
"Move14Kiser." called out Mrs. Winters.
I was now leaning against Santa Claus' leg and I was looking15into his eyes. His face was less than an inch from mine.
"Can I16you Santa?" I asked him.
The next thing I knew Mrs. Winters had caught me up by my shirt collar and was17me away from the line of children.
I sat down in my chair just crying. Once in a while I would18at the stage to see if my gift was still sitting by Santa Claus.
When we all lined up waiting, I19"HO HO HO" coming from behind me.
As I20, there stood Santa Claus holding my large box. Then he knelt down and he hugged my neck as hard as he could.

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.
【小题1】From the passage we know that scientists have ______.
A.tried to clone animals |
B.cloned many kinds of animals |
C.been able to clone pets for people |
D.once cloned goats successfully |
A.clone pets for people |
B.store the DAN of people’s pets for cloning one day |
C.make pets members of a family |
D.collect different ideas on cloning from people |
A.they think it would be too expensive |
B.they don’t think scientists will one day be able to clone their pets |
C.they think the cloned pet would not be the one they once had |
D.they don’t want to give any love to the cloned pet |
A.looked different from the pet you once had |
B.turned out to be another kind of animal |
C.had a different character |
D.were just the same pet your once had |
Plants can’t communicate by moving or making sounds, as most animals do. Instead, plants Produce volatile compounds, chemicals that easily change from a liquid to a gas. A flower’s sweet smell, for example, comes from volatile compounds that the plant produces to attract insects such as Bugs and bees.
Plants can also detect volatile compounds produced by other plants. A tree under attack by Hungry insets, for instance, may give off volatile compounds that let other trees know about the Attack. In response, the other trees may send off chemicals to keep the bugs away ——or even Chemicals that attract the bugs’ natural enemies.
Now scientists have created a quick way to understand what plants are saying: a chemical Sensor(传感器)called an electronic nose. The “e-nose” can tell compounds that crop plants make When they’re attacked Scientists say the e-nose could help quickly detect whether plants are being Eaten by insects. But today the only way to detect such insects is to visually inspect individual Plants. This is a challenging task for managers of greenhouses, enclosed gardens than can house Thousands of plants.
The research team worked with an e-nose than recognizes volatile compounds. Inside the device, 13 sensors chemically react with volatile compounds Based on these interactions, the e-nose gives off electronic signals that the scientists analyze using computer software.
To test the nose, the team presented it with healthy leaves from cucumber, pepper and tomato plants, all common greenhouse crops. Then scientists collected samples of air around damaged leaves from each type of crop, These plants had been damaged by insects, or by scientists who made holes in the leaves with a hole punch(打孔器). The e-nose, it turns out, could identify healthy cucumber, pepper and tomato plants based on The volatile compounds they produce, It could also identify tomato leaves that had been damaged. But even more impressive, the device could tell which type of damage ---- by insects or with a hole Punch ---- had been done to the tomato leaves.
With some fine-tuning, a device like the e-nose could one day be used in greenhouses to quickly spot harmful bugs, the researchers say. A device like this could also be used to identify fruits that are perfectly ripe and ready to pick and eat, says Natalia Dudareva, a biochemist at Purdue University in West Lafayette, Ind. who studies smells of flowers and plants. Hopefully, scientists believe, the device could bring large benefits to greenhouse managers in the near future.
