3．Complete  the  exercise withoutreferring（参阅）to a dictionary．
10．A  new study of 8，000young people in the Journal of Health and Social Behavior shows that although love can make adults live healthily and happily，it is a bad thing for young people．Puppy love（早恋）may bring stress for young people and can lead to depression．The study shows that girls become more depressed than boys，and younger girls are the worst of all．
The possible reason for the connection between love and higher risk of depression for girls is"loss of self"．According to the study，even though boys would say"lose themselves in a romantic relationship"，this"loss of self"is much more likely to lead to depression when it happens to girls．Young girls who have romantic relationships usually like hiding their feelings and opinions．They won't tell that to their parents．
Dr Marianm Kaufman，an expert on young people problems，says 15% to 20% young people will have depression during their growing．Trying romance often causes the depression．She advises kids not to jump into romance too early．During growing up，it is important for young people to build strong friendships and a strong sense of self．She also suggests the parents should encourage their kids to keep close to their friends，attend more interesting school activities and spend enough time with family．
Parents should watch for signs of depression-eating or mood changes-and if they see signs from their daughters or sons，they need to give help．The good news is that the connection between romance and depression seems to become weak with age．Love will always make us feel young，but only maturity gives us a chance to avoid its bad side effects．
28．What's the main idea of the passage？C
A．Romance is a two-edged sword for adults．
B．Parents should forbid their children's love．
C．Puppy love may bring young people depression．
D．Romance is good for young people．
29．Which of the following is more likely to have depression？D
A．Careless parents whose children are deep in love．
B．Young people who have a strong sense of selfishness．
C．Young boys whose parents watch for their behavior．
D．Young girls who always hide their feelings and opinions．
30．What can be inferred from the passage？B
A．Lacking love can lead young people to grow up more quickly．
B．The older a woman is，the less likely she seems to lose herself in romance．
C．Early love makes young people keep close to their friends and parents．
D．Parents should help their children to be aware of the signs of depression．
31．What's the author's attitude towards puppy love？A
A．disapproving        
B．confused           
C．neutral      
D．scared．
20．The bad girl deserved to be punished---nobody took pity on her．
7．Jo worked at a bush school （56）whose classroom were made from bamboo and grass．There's no electricity or water there．It （57）tookthe  students about two hours（58）to get （get） to the school．Jo hoped to make some difference to the children's lives by teaching them．The other day，Jo visited Tombe's home．When they arrived （59）atthe village，Tombe's mother who （60）hadbeen working （work） in the garden，started crying"Ieee Ieee"．Tombe's father led them to his house，（61）a  low bamboo hut with grass （62）sticking  （突出） out of the roof，（63）what  he could only see a few tin plates and cups and greens．That night Jo and Jenny slept on a （64）newly （新近地） made platform．They left the village the next morning （65）after many goodbyes and shaking of hands．
4．It was by accident that he broke the valuable vase．He didn't do that onpurpose （故意）．
5．I had been called to examine a ten-year-old dog （61）named （name） Belker．I examined Belker and found he was dying of cancer．I told the family I couldn't do anything．
Shane，a six-year-old in the family，seemed so calm，petting the old dog （62）for the last time．I wondered if he understood what was（63）going （go） on．Within a few minutes，Belker slipped peacefully away．
The little boy seemed to accept the fact without any difficulty（64）or confusion．We sat together for a while after（65）Belker's （Belker） death，wondering aloud about the sad fact that animal （66）lives （life） are shorter than human lives．
Shane，who had been listening quietly，said，"I know why．"
We all turned to him．What came out of his mouth next surprised me （67）greatly （great）．I'd never heard a（68）more （much） comforting explanation．It has changed the way I try and live．
"People are born so that they can learn how to live a good life-like loving everybody all the time and （69）being （be） nice，right？"The six-year-old continued，"Well，dogs already know（70）how to do that，so they don't have to stay as long．"
