Passage one

On June 26, 2000, two scientists, called Francis Collins and Craig Venter, told the world that they could now read the whole "map" of the human body: DNA. DNA is something that everybody has, and it tells the body what to do. DNA is the reason that we look like our mother and father, because we get some of their DNA to make our own.

People have been trying to understand the human body for a long time. In 1860, Gregor Mendel discovered a special reason why we look the same as other people in our family. It is because of small things named "genes" in our body. In 1953, James Watson and Francis Crick made another discovery and found out that those small parts are real messages written in the DNA with a special language.

In 1961, Marshall Nirenberg and Johann Matthaei found a message in DNA showing how DNA tells the cell (细胞) to build its parts. Scientists have now found all the words in the DNA map, but we still do not understand what they all do. By understanding what just one "word" means, we can help save more people from several illnesses.

Most people hope that this will help make better medicine and help sick people. Other people worry that when people begin to know more words and find out lots of other information, we might use it in a wrong way, just to make people more attractive, or stop sick people from getting jobs. Man would have to meet a lot of trouble if DNA technic wasn’t limited in use.

Passage two

I find it annoying and funny when I think about how we use protective or decorative wrappings (装饰性包装) in this country.

When I come home from the supermarket and start to unpack, I am always shocked at the layers of wrappings we cover our food with.

There is hardly anything we buy that doesn't come in at least two wrappings, and then several of them are gathered by the shop assistant and put into a small bag. Then several of the small bags are grouped together and put into a big bag. If you have several big bags with small bags in them, they give you a cardboard box to put the packages-in-the-little-bags-in-the-big-bags in.

A lot of things we buy wouldn't really need any protective wrapping at all. The skin of an orange protects an orange pretty well for most of its natural life, but we aren't satisfied with what nature has given it. We wrap them in plastic or put them in a net bag, and then in a paper bag. The orange inside the skin, inside the plastic which is in the paper bag, must wonder where it is.

A box of biscuits often has waxed paper(蜡纸) next to the biscuits, a cardboard box holding the food and then a decorative wrapping around it.

A relative of ours bought a new sofa recently because she liked the fine leather (皮革) it was covered with. She liked it so much she didn't want it to get dirty, so she bought a cloth cover to put over it.

We may never again see the leather she's protecting.

6、According to the author, the use of protective wrappings______. A．can be wasteful and unnecessary B．makes everything look funny
