China’s first moon rover,Yutu,or Jade Rabbit,separated from the lander early on Sunday,December l5,2013,several hours after the Chang’e-3 probe (探测器) soft-landed on the lunar surface.The l 40 kg six-wheeled rover touched the lunar surface at 4:35 a.m.,leaving deep trace on the loose lunar soil. The process was recorded by the camera on the lander and the images were sent to the earth,according to the Beijing Aerospace Control Center.

After the separation,the rover and lander will take photos of each other and start their own scientific explorations. Engineers made final checks of the environment of the landing site,the situation of the probe and sent signals of separation to Chang’e-3.

Yutu, on the top of the probe,extended its solar panel and started to drive slowly to the transfer mechanism (机械装置) at 3:10.The transfer mechanism unlocked at 4:06 with one side reaching the moon’s surface,allowing the rover to descend to the surface following a ladder mechanism.

Chang’e-3 landed on the moon’s Sinus Iridum,or the Bay of Rainbows,at 9:11 p.m.Saturday,making China the third country in the world to carry out such a rover mission after the United States and former Soviet Union.

In ancient Chinese mythology,Yutu was the white pet rabbit of the lunar goddess Chang’e.The name for the rover was selected following an online poll that collected several million votes from people around the world.

The rover,1.5 meters long with its two wings folded,1 m in width and l.1 m in height,is a highly efficient robot controlled by the command center from the earth.It will face challenges including temperature differences of more than 300 degrees Celsius on the moon.

Yutu will survey the moon’s geological structure and surface substances and look for natural resources for three months,while the lander will conduct in-situ (现场) exploration right at its landing site for one year.

Jenny was a pretty five-year-old girl. One day when she and her mother were checking out at the grocery store, Jenny saw a plastic pearl (珍珠) necklace priced at $2.50. Her mother bought the necklace for her on condition that she had to do some homework to pay it off. Jenny agreed. She worked very hard every day, and soon Jenny paid off the necklace. Jenny loved it so much that she wore it everywhere except when she was in the shower. Her mother had told her it would turn her neck green!

Jenny had a very loving daddy. When Jenny went to bed, he would read Jenny her favorite story.

One night when he finished the story, he said, “Jenny, could you give me your necklace?”

“Oh! Daddy, not my necklace!” Jenny said. “But you can have Rosy, my favorite doll. Remember her? You gave her to me last year for my birthday. Okay? ”

“Oh no, darling, that’s okay.” Her father brushed her cheek with a kiss. “Good night, little one.

A week later, her father once again asked Jenny for the necklace after her favorite story. “Oh, Daddy, not my necklace! But you can have Ribbons, my toy horse. Do you remember her? She’s my favorite.”

“No, that’s okay,” her father said and brushed her cheek again with a kiss. “God bless you, little one. Sweet dreams. ”

Several days later, when Jenny’s father came in to read her a story, Jenny was sitting on her bed and her lip was trembling. “Here, Daddy,” she said, holding out her hand. She opened it and her beloved pearl necklace was inside. She let it slip into her father’s hand.

With one hand her father held the plastic pearl necklace and with the other he pulled out of his pocket a blue box. Inside the box was a real, beautiful pearl necklace. He had had it all along. He was waiting for Jenny to give up the cheap necklace so he could give her a real one.

Sure, we've all heard that we should get more sleep. The realities of life often make it become "we should get more sleep later." 1. The result is that you wake up the next day feeling like a role of The Walking Dead. Here are four ways you can adjust your biology in order to pay less for staying up.

● Move around.

Exercising before bed is a sure way to keep awake. That's why you shouldn't do it when you want to go to sleep, and it is also why hitting the gym, or even some fast push-ups can tell your body that it's not time for bed. Being physically exhausted isn't fun when you are trying to stay up late. 2.

● Eat more protein.

Few people think about the fact that the brain and body use a lot more energy when we're awake. If you are pulling an all-nighter, you're going to need a lot more food than you are used to eating. 3. To stay awake, plan to eat larger meals than normal and to eat them more frequently.

● Drink the right stuff.

It's tempting (诱人) to switch to sugary caffeine drinks like Red Bull, but the sugar will lead to a crash. Instead, if you want to use caffeine, drink early in the evening so it'll wear off by the time you want to sleep.

4. Don't make it worse by drinking sugar.

● 5.

Turn the lights down at night because bright lights keep you awake. For three or four hours after you're exposed to bright white light, your body won't make melatonin, a must for deep sleep. You will sleep better if you turn the lights a little bit down.

A. Turn the lights off.

B. Avoid bright lights.

C. Just do enough to get energetic.

D. And your body can never bear something like that.

E. Your brain can use up to 25 percent of your total calories.

F. When you stay up late, your blood sugar becomes abnormal.

G. There is either more work to be done, or more fun to be had, or both.
