    A recent announcement by scientists that they have successfully cloned the first human embryo(胚胎) has caused much debate and has shocked many people around the world. On the one hand, some scientists point out that if you clone an embryo, you can produce valuable tissues(组织) and organs that could be used to save human lives. On the other hand, many people, including some scientists, disagree and fear that if mankind interferes with (干涉) nature in this way, they may be on their way to producing a real-life Frankenstein's monster.

Cloning is producing an exact copy of a plant or an animal using its cells. The first mammal to be cloned successfully from an adult cell was Dolly—the sheep. She was born in 1996 and died in early 2003, at a much younger age than normal. When she was born, many people were angry because they thought cloning would create more diseases in the animal world. However, in general the scientists were praised for their wonderful scientific breakthrough.

    The Scottish scientist who created Dolly, Ian Wilmut, is shocked that some scientists are now considering cloning human beings. Although he researches cloning, he has never thought of creating copies of humans. Instead, he thinks the scientists should concentrate on creating new tissues and organs that could eventually be used to cure diseases like cancer. However, some people consider that cloning human embryos with the intention of destroying them shows no respect for human lives.

    While cloning human embryos is illegal in many countries, some scientists are already pushing ahead with the research so as to deliver a cloned human baby. Severino Antinori, an Italian doctor, is one of the leaders in this field of research. He has declared that he wants to be the first to clone a human being.

In China, scientists have focused their efforts on cloning animals, as well as stem cells to be used in medical research. China has succeeded in producing clones of cows and goats, and continues to research ways in which cloning can benefit mankind.

“Nature does not hurry, yet everything is accomplished.”—Lao Tzu

If you are in a city where everyone rushes, realize that you don't have to be like everyone else. You can be different. You can walk instead of driving in rush hour traffic. You can be on your iPhone or Blackberry less, and disconnected sometimes. Your environment doesn't control your life—you do. I'm not going to tell you how to give you a step-by-step guide to moving slower.      

    ⒈Do less.

Cut back on your projects, on your task list, on how much you try to do each day.       Pick 2-3 important things— or even just one important thing— and work on those first. Save smaller, routine tasks for later in the day, but give yourself time to focus.

    ⒉      Meeting are usually a “big waste of time”. And they eat into your day, forcing you to squeeze the things you really need to do into small windows, and making you rush.

    ⒊Start to put off or cancel the unnecessary.

    When you do the important things with focus, without rush, there will be things that get pushed back, and that don't get done. And you need to ask yourself:      What would happen if I stopped doing them?

    ⒋Practice mindfulness.

          Don't care so much about future or the past. When you eat, fully appreciate your food. When you are with someone, be with them fully. When you are walking, appreciate your surroundings, no matter where you are.

    Try these things out. Life is better when unrushed. Remember the quote: if nature can get everything done without rushing, so can you.

A. Have fewer meetings.

B. How necessary are these things?

C. Simply learn to live in the present.

D. Focus not on quantity but on quality

E. Give yourself more time to get ready and get there.

F. The world likely won't end if you don't pass one of the examinations.

G. But here are some things to consider and perhaps adopt, if they work for your life.
