Everything on Earth that scientists can see, measure or study is made of
atoms and atoms are named by what types of elements(元素)they are. You probably
know the name of many elements, such as oxygen, gold or hydrogen. In any
case,elements are everywhere:You,your shoes,your desk,cars,water and air are all
made of elements.
Now, there’s a new kid on the block: copernicum.
This element was officially named on February 19,but the element itself is
n’t new. German scientists made and observed it in 1996.But In the l4 years
since then, other scientists have been working to study and validate(证实)the
original findings. Validation is an important part of the scientific process
because it shows that a scientific discovery was not a mistake.
All that hard work finally paid off when the element finally received its
name,copernicum,from the International Union of Pure and Applied Chemistry
Copernicum is named in honor of Nicolaus Copernicus, a 16th century Polish
scholar who proposed that Earth moves around the sun and that Earth turns on its
own axis.
Scientists organize all the elements on a chart called the Periodic Table,
Each element gets a symbol and its own number, and copernicum gets the symbol Cn
and the number 112. This number means that inside every atom of copernicum are
ll2 protons(质子).The lightest element hydrogen has only one proton inside each
atom. Its ll2 protons make copernicum the heaviest known element with a name. It
was first observed by Sigurd Hofmann, a scientist in Germany. In l996,Hofmann
mad his team had to figure out a way to get all the protons together and
stick.They used a machine that can speed up atoms up to 10 percent the speed of
light. After a week of working on these high-speed co llisions(碰撞), Hofmann’s
team found copernicum even though it quickly disappeared.
Now, 14 years after Hofmann’s experiment, other scientists are able to make
copernicum and validate Hofmann’s original work. Scientists are excited about
copernicum. If such a super heavy atom can be created, then even heavier
elements might be waiting in the future “One of the exciting things is,how far
can we keep going?” says nuclear chemist Paul Karol.
54. What do we know about copernicum?
A. It is the heaviest element so far B. It was officially named in l996
C. It is a newly-discovered element D. It is the most difficult element to
validate
55. Why is copernicum named after Nicolaus Copernicus?
A. Because he proved the existence of the element
B. Because he put forward the sun-centered theory
C. Because he observed the element in the l6th century
D. Because he designed the Periodic Table for all the elements
56. By asking “how far can we keep going?” Karol means .
A. how many elements p eople can find in the future
B . how soon people can find another Dew heavy element
C. how long people can walk carrying the heavy element
D. how long people can continue to research into copernicum
57. What is the best title for the passage?
A. A New Element Has Been Discovered
B. The Periodic Table Is Changed Again
C. The Heaviest Named Element Is Official
D. Superheary Copernicum Needs Its Place

Learning to save money when you’re young is an important lesson. All good
lessons and habits begin early, and saving is a skill that everyone needs. Many
people-adults included-do not have a good sense of saving for the long run.
I have been lucky to learn this lesson early because I have had a
grass-cutting business since I was 10 years old. Of the money I make I spend
about 10 percent and save the other 90.
Making sure you save and don’t spend too much is a good way to build up
wealth. I have put my earnings in a bank. Many teens I know spend all the money
they earn so it never has a chance to grow. Young people should realize that
their teenage years are a great time to begin saving.
At high school,if you have a part time Job,you should have fun with some of
the money. But you should also save some so that it will grow. Then you can
begin planning for your future. When you spend money,you not only lose that
money,but also lose the interest you could have earned by saving it.
After high school, college is expensive and then “real” life begins, with
expenses such as food and rent. If you can hold onto a good percentage of the
money you earn as a teen, going to college will be much easier.
Later in life it can be hard to start saving because general costs of
living are more expensive and you may only have enough to pay your bills. If you
want to buy a house and have a family, you need money to star with,which comes
from saving.
Many say money cannot make you happy, and this is true. But money can help
you to lead a sale life.
Saving early will mean yon will have to work for fewer years when you aye
older. It will also allow you to spend time doing the things that you want to
do.
In addition to this,it means you can live the way you want to without
worrying.
