【解析】此题重点考查too much,much too的区别;more和another的区别。too much “太多”用作形容词,后接不可数名词。也可用作代词。much too "太”是副词。后接形容词或副词。too much当中的too是副词,修饰much. much too当中的much是修饰too的,用来加强too的语气。
another 和 more 跟数词结合,一般都表示“额外的数量,另外一些”的意思,但两者也有区别: another 位于数词的前面,而 more 后既可跟可数名词也可跟不可数名词。
On June 26, 2000, two scientists, called Francis Collins and Craig Venter, told the world that they could 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 Matthaci 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(限制)in use.
