科学的英语作文高中【第一篇】

Science,as the basis for the development of contemporary society,is actually a double-edged sword which can be either beneficial or detrimental to human is obvious that we can not live so happily and conveniently without scientific has pervaded every aspect of our lives and better our working and living conditions as well as our mental ,any scientific research must not violate the fundamental ethical and moral laws of gh scientists hold goals to make differences and breakthroughs to contribute to human beings,occupations such as human cloning engineering,computer viruses production,nuclear weapons, spite of personal interests,should be taken into put,if it was not the case,our society would have to encounter numerous unexpected problems like moral complications,threats of nuclear explosion and other novel patterns of a result,peace and harmony will evaporate into the air,leaving a world with jeopardy and horror,even leading to human for this reason,it is crucial to well orient the direction of scientific research.

Modern technology makes life more convenient; tools are the milestores of the technology as well as human being’ s progress.

Men used to cut trees with hand saw. But now, by using electronic saw they can cut down a tree in only a few minutes. Another example is more vivid: You have something urgent which has to be informed to your friend whose house is two hour’s ride away. You probably want to make a phone call. But no telephone is installed in your friend’ s home. What could you do? Nowadays, with modern technology advanting, using internet is popular with us. Some years ago, people had to get what they wanted through looking into a lot of information; at last people could become tired and spent too much time. Now, if you use Internet, all becomes a piece of cake. Only by clucking, you will gain what you expect.

We all hope that modern technology will reach a higher level, because modern technology makes life more convenient indeed.

Buckyball Traps Single Water Molecule【第三篇】

The carbon molecule known as a buckyball, a member of the fullerene family, can act as a cage for a variety of other chemicals. And now researchers have used one to trap a single molecule of water. The work appears in the journal Science.

[Kei Kurotobi and Yasujiro Murata, A Single Molecule of Water Encapsulated in Fullerene C60]

Placing a molecule that's essential to life within a spherically symmetrical one could let researchers learn more about each.

Water molecules stick together, because they carry a slight charge on each end. As the positive pole of one H2O attracts the negative pole of another, the molecules cling tightly together. You can't separate a single water molecule from its fellows with a tiny pair of tweezers, so isolating it in a carbon cage may reveal new secrets about the intrinsic nature of a lone H2O.

What about the cage itself? Researchers already know that buckyballs refuse to dissolve in water, sometimes even floating like miniature beach balls. But what happens when the water is within? Putting polar molecules inside buckyballs may influence the chemical behavior of their outsides, and create new molecules with unique properties. Not to mention making our understanding even…fuller.

科学的英语作文高中【第四篇】

Think of the weirdest creatures you’ve even seen in a sci-fi film. Now think of this: there are far stranger, albeit smaller, critters living in your own home. And Rob Dunn at North Carolina State University wants you to go on safari to find them.

Research has been done on the diversity of bacteria, fungi and other organisms that live on our skin, in our guts, even in our belly buttons.

But there are other entire ecosystems that surround us. And scientists want to understand how they differ based on how and where we live. What’s the tiny life like on a doorframe in Brooklyn compared with that in Des Moines? Or how do fridge microbes of an urban singleton stack up with those of a suburban family?

The research team seeks ten volunteers from each state, five urban and five rural. Each volunteer will get a kit of vials and swabs, along with instructions about where and how to swipe – such as door frames, couch cushions, refrigerators, even yourself. The samples will be analyzed, to uncover the secrets of our microscopic companions. To find out more, go to
