14．Everybody has his own hobbies：some are fond of collecting stamps，coins，etc．，some like swimming，and there are some who like reading or music--all these are good hobbies．
Nowadays，most teenagers are crazy about"hit-song"．From those songs we can learn many phrases which we can not find in books．Although teenagers like those songs very much，adults dislike them．And if they indulge （沉溺） in them，it would be a waste both of time and of money．
This should not be considered as a good hobby．
The worst hobbies of all are smoking and gambling （賭博）．Smoking is bad for our bodies．
Some men like to smoke in public places，and do not care about other people's feelings．Gamb|ing will make you lose everything．You may lose your money，family and friendship．
So，why don't we do something useful？Some good hobbies，like collecting stamps and reading，can help us get much knowledge．Music can make us happy，and sports can keep us healthy．So why not take the good and give up the bad？

106、We canlearn many phrases from hit songs but we can't find them inbooks．
107、It is a waste of both time andmoney for teenagers tospend too much time on hit songs．
108、Smoking and gambling are the worst hobbies of all．Both of them arebad for us．
109、Reading can help us getknowledge，and sports can keep ushealthy/fit．
110、The writer advises us to take thegood hobbies andgive up the bad hobbies．

11．DNA is the whole"map"of the human body．It is something that all humans have，and it tells the body
what to do．DNA is the reason that we look like our parents，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 I860，Mr Mendel discovered why we look the same as other people in our family．It is because of small things called"genes"（基因） in our body．In 1953，two scientists，Watson and Crick，found out that those small parts are really messages．They're written in the DNA with a special language．
In 1961，another two scientists found the first"word"that they could understand in that language．It
shows how DNA tells the cell （細(xì)胞） to build its parts，（有幾個單詞看不清） 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 to save people from several illnesses．So the more we understand，the more doctors will be able to do．
Most people hope that this will help to make better medicine and help sick people：Other people worry that when we learn more"words"and find out more information，we will use it in the wrong way，just to
make people more attractive （有吸引力的），or stop sick people getting jobs．Man would have to meet a lot of trouble if DNA technic wasn't limited in use．

31．When did Mr．Mendel discover why we look the same as other people in our family？D
A．In 2000．
B．In 1961．
C．In 1953．
D．In 1860．
32．How can we help sick people if we understand more"words"in the DNA map？A
A．Make better medicine．
B．Make them get jobs．
C．Make maps for them．
D．Make them attractive．
33．Which one is not true according to the article？B
A．We look like our parents because of"genes"in our body．
B．We have understood what all the words in the DNA map do．
C．DNA is the whole"map"of the human body．
D．DNA tells the cell to build its parts．
34．What does the underlined word"limited"mean？A
A．有限的 
B．充分的 
C．特別的
D．部分的
35．Where can we probably read the article？B
A．A sports newspaper．
B．A science magazine．
C．A history book．
D．An ad．
