Dear Mr. Dyson,

I would like apply to become an assistant in your company.

I will expect to get an Master¡¯s degree in mechanical engineering from BeijingUniversity in 2016. In the past few years, I had got experience in designing new project.

I worked in my holidays for a company designed engines for jeeps. I helped their design several parts of the new engine, it made me think I would like to work in a real inventor¡¯s company.

I would be grateful when you would consider employ me in your company.

Yours sincerely,

Liu Xue

¡¾ÌâÄ¿¡¿While astronauts in space get to do many exciting things, they miss out on ordinary things that we all take for granted¡ªbeing 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 (É豸) 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 (Ô­ÐÍ) that begins by creating a single slice of dough (ÃæÍÅ) that is cooked and printed at the same time. Then comes the tomato ¡°sauce¡± ¡ª 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 (ÅäÁÏ) 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!

¡¾ÌâÄ¿¡¿Kids with special needs refer to any kid who might need extra help because of a medical,emotional,or learning problem.For example,kids who cannot walk need wheelchairs.They not only need equipment that helps them get around,but they might need to have ramps£¨ÆÂµÀ£©or elevators available.¡¾1¡¿

We all regard receiving presents as a pleasant experience and yet it can be one of the most awkward situations. It is often difficult to look pleased when you receive a gift which is entirely useless or the wrong size.

However, you have no right to change an article purchased just because it does not fit or is not to your liking. Worse still, the agreement on the sale is between the person who bought it and the shop.

So you will have to tell your favorite aunt that the T-shirt does not fit. But an exchange is not always that simple because there has to be a good reason for it.

For example, if the buyer was told that a switch was voice operated and later found out it was not, then action could be taken. You would have the right to return it and get the money back.

But if you are returning something, no matter what the reason is, you will be expected to have proof of purchase. If the receipt cannot be found, then it is possible to use another proof of purchase such as a credit card receipt.

Many big stores have a much more tolerant policy towards returns and see it as a gesture of goodwill to exchange goods without question. Stores including Marks & Spencer are well known for their ¡°no argument¡± policy on returned goods.

So if a shop refuses to exchange the goods or to offer a refund(ÍË¿î), the seller is likely to be within his legal rights unless there is something wrong with the goods. In that case, the boot is on the other foot. You have every right to demand a cash refund or a replacement, but only if you have returned it within a ¡°reasonable¡± time.

Some shops and stores expect things to be returned within a week of purchase, while others may permit a much longer time limit. In any case if you return a thing

after what is considered a ¡°reasonable¡± time, then all you are legally entitled to is the cost of repair.

A. It is unlike anything you would buy for yourself.

B. If all of these have been lost, you may have to rely on a witness.

C. However, shoppers should remember this is a privilege, not a right.

D. Unfortunately, the law does not explain what is meant by ¡°reasonable¡±.

E. All you can do is exchange it after your friend or relative has gone home.

F. Either the thing has to be broken or unsuitable for the job it was intended to do.

G. You should make clear what your legal position is before returning goods to the shops.

Freeflyers: Modem Skydivers

Have you experienced the thrilling sport¡ªfreeflying? Imagine falling towards the planet Earth at ¡¾1¡¿ awesome speed of 300 kilometers per hour. You start your fall from over four kilometers above the Earth. And you have less than one minute before you pull your parachute (½µÂäÉ¡£©cord. You are falling ¡¾2¡¿ fast that just turning your head can send you off ¡¾3¡¿ a different direction. This is the wild side of a sport that has not found its limit¡ªfreeflying.

Freeflying ¡¾4¡¿ (base) on the more traditional skydiving, ¡¾5¡¿ of which are eye-catching. However, it is more terrifying to watch freeflyers create formations and movements. Freeflyers, ¡¾6¡¿ the name suggests, enjoy the more spontaneous(¼´Ð˵ģ©thrill of doing their own things.

The wildest trip for a freeflyers is falling ¡®head down¡¯. Falling ¡®head first¡¯ requires a great deal of control, which means ¡¾7¡¿ (travel) not only fast but also steadily. Even the ¡¾8¡¿ (slight) movement has a great effect on your direction.

They wear the amusing jumpsuits, strange helmets and smaller parachutes. ¡¾9¡¿ (actual), their parachutes are about one quarter the size of the traditional skydiver¡¯s parachutes. It is only in the last few years ¡¾10¡¿ freeflying has gained any real public acceptance.
