While astronauts in space get to do many exciting things, they miss out on ordinary things that we all take for granted-being able to walk on firm ground, hanging out with family and digging into a slice of hot steaming pizza. Though not much can be done about the first two things, there may soon be a solution to the third one, thanks to this cool 3-D pizza printer!
About a year ago, NASA offered $125,000 to Anjan Contractor, a 3-D technology expert, to build a device（设备）that would allow astronauts to make pizza on demand. The mechanical engineer promised that his invention would produce pies in large quantities that looked, tasted and even smelled like pizza made in common ovens.
Late last year, the engineer presented a video of his first prototype（原型）that begins by creating a single slice of dough（面团）that is cooked and printed at the same time. Then comes the tomato “sauce” —a mix of tomato powder, oil and water and finally, a protein slice that resembles cheese. While the video doesn’t show the baking process, the inventor says that once the pizza is printed, it can be ready to be consumed in 7 seconds.
While the pie in the video looks delicious enough to attract any pizza lover, Anjan Contractor is far from ready for astronauts. That’s because he still has to find a solution to make the food container in the printer last for 30 years. Though that may sound unrealistic, actually it is not.
Anjan Contractor believes that the only way that is possible is that the water is removed from all the ingredients（配料）and then they are reduced to the powder form. This, as you can imagine, will not be so easy. But, while the printer may not be ready for space, it certainly looks ready enough for people on earth. Hopefully, NASA and Contractor will consider selling it to those not fortunate enough to go to Mars!Why does the author mention the things that astronauts in space cannot do?

Do's and Don'ts in Whale(鲸) Watching
The Department of Fisheries and Oceans has developed guidelines for whale watching in Johnstone Strait, where killer whales are found on a daily basis each summer. It is strongly recommended that vessel(船只) operators follow these guidelines for all kinds of whales.
· Approach whales from the side, not from the front or the back.
· Approach no closer than 100 metres, then stop the boat but keep the engine on.
· Keep noise levels down - no horns, whistles or racing of engines.
· Start your boat only after the whales are more than 100 metres from your vessel.
· Leave the area slowly, gradually moving faster when you are more than 300 metres from the whales.
· Approach and leave slowly, avoiding sudden changes in speed or direction.
· Avoid disturbing groups of resting whales.
· Keep at low speeds and remain in the same direction if traveling side by side with whales.
· When whales are traveling close to shore, avoid crowding them near the shore or coming between the whales and the shore.
· Limit the time spent with any group of whales to less than 30 minutes at a time when within 100 to 200 metres of whales.
· If there is more than one vessel at the same observation spot, be sure to avoid any boat position that would result in surrounding the whales.
· Work together by communicating with other vessels, and make sure that all operators are aware of the whale watching guidelines.

More than 10 years ago, it was difficult to buy a tasty pineapple. The fruits that made it to the UK were green on the outside and, more often than not, hard with an unpleasant taste within. Then in 1996, the Del Monte Gold pineapple produced in Hawaii first hit our shelves.
The new type of pineapple looked more yellowy-gold than green. It was slightly softer on the outside and had a lot of juice inside. But the most important thing about this new type of pineapple was that it was twice as sweet as the hit-and-miss pineapples we had known. In no time, the Del Monte Gold took the market by storm, rapidly becoming the world's best-selling pineapple variety, and delivering natural levels of sweetness in the mouth, up until then only found in tinned pineapple.
In nutrition(营养) it was all good news too. This nice-tasting pineapple contained four times more vitamin C(维生素C) than the old green variety. Nutritionists said that it was not only full of vitamins, but also good against some diseases. People were understandably eager to be able to buy this wonderful fruit. The new type of pineapple was selling fast, and the Del Monte Gold pineapple rapidly became a fixture in the shopping basket of the healthy eater.
Seeing the growing market for its winning pineapple, Del Monte tried to keep the market to itself. But other fruit companies developed similar pineapples. Del Monte turned to law for help, but failed. Those companies argued successfully that Del Monte's attempts to keep the golden pineapple for itself were just a way to knock them out of the market.

C
Napoleon, as a character in Tolstoy’s War and Peace, is more than once described as having “fat little hands.’’ Nor does he “sit well or firmly on the horse.’’ He is said to be “undersized.’’ with“short legs’’ and a “round stomach”. The issue here is not the accuracy of Tolstoy’s description--it seems not that far off from historical accounts but his choice of facts：other things that could be said of the man are not said. We are meant to understand the difference of a warring commander in the body of a fat little Frenchman. Tolstoy’s Napoleon could be any man wandering in the streets and putting a little of powdered tobacco up his nose—and that is the point.
It is a way the novelist uses to show the moral nature of a character. And it turns out that, as Tolstoy has it, Napoleon is a crazy man. In a scene in Book Three of War and Peace, the wars having reached the critical year of 1812,Napoleon receives a representative from the Tsar(沙皇), who has come with peace terms. Napoleon is very angry：doesn’t he have more army? He, not the Tsar, is the one to make the terms. He will destroy all of Europe if his army is stopped. “That is what you will have gained by engaging me in the war!” he shouts. And then, Tolstoy writes, Napoleon “walked silently several times up and down the room, his fat shoulders moving quickly.’’
Still later, after reviewing his army amid cheering crowds, Napoleon invites the shaken Russian to dinner. “He raised his hand to the Russian’s…face,” Tolstoy writes, and “taking him by the ear pulled it gently….” To have one’s ear pulled by the Emperor was considered the greatest honor and mark of favor at the French court. “Well, well, why don’t you say anything?’’ said he, as if it was ridiculous in his presence to respect any one but himself, Napoleon.
Tolstoy did his research, but the composition is his own.Tolstoy’s description of Napoleon in War and Peace is _________.
| A．far from the historical facts | B．based on the Russian history |
| C．based on his selection of facts | D．not related to historical details |
Napoleon was angry when receiving the Russian representative because _________.
| A．he thought he should be the one to make the peace terms |
| B．the Tsar's peace terms were hard to accept |
| C．the Russians stopped his military movement |
| D．he didn’t have any more army to fight with |
What did Napoleon expect the Russian representative to do?
| A．To walk out of the room in anger. | B．To show agreement with him. |
| C．To say something about the Tsar. | D．To express his admiration. |
Tolstoy intended to present Napoleon as a man who is _________.
| A．ill-mannered in dealing with foreign guests | B．fond of showing off his iron will |
| C．determined in destroying all of Europe | D．crazy for power and respect |
What does the last sentence of the passage imply?
| A．A writer doesn’t have to be faithful to his findings. |
| B．A writer may write about a hero in his own way. |
| C．A writer may not be responsible for what he writes. |
| D．A writer has hardly any freedom to show his feelings. |
Sometimes you'll hear people say that you can't love others until you love yourself. Sometimes you'll hear people say that you can't expect someone else to love you until you love yourself. Either way, you've got to love yourself first and this can be tricky. Sure we all know that we're the apple of our parents' eyes, and that our Grandmas think we're great talents and our Uncle Roberts think that we will go to the Olympics. but sometimes it's a lot harder to think such nice thoughts about ourselves. If you find that believing in yourself is a challenge. it is time you build a positive self-image and learn to love yourself.
Self-image is your own mind's picture of yourself. This image includes the way you look, the way you act, the way you talk and the way you think. Interestingly, our self-images are often quite different from the images others hold about US. Unfortunately, most of these images are more negative than they should be. Thus changing the way you think about yourself is the key to changing your self-image and your whole world.
The best way to defeat a passive self-image is to step back and decide to stress your successes. That is, make a list if you need to, but write down all of the great things you do every day. Don't allow doubts to occur in it.
It very well might be that you are experiencing a negative self-image because you can't move past one flaw or weakness that you see about yourself. Well, roll up your sleeves and make a change of it as your primary task. If you think you're silly because you aren't good at math, find a tutor. If you think you're weak because you can't run a mile, get to the track and practice. If you think you're dull because you don't wear the latest trends, buy a few new clothes. But remember, just because you think it doesn't mean it's true.
The best way to get rid of a negative serf-image is to realize that your image is far from objective, and to actively convince yourself of your positive qualities. Changing the way you think and working on those you need to improve will go a long way towards promoting a positive self-image. When you can pat(拍) yourself on the back, you'll know you're well on your way. Good luck!
