2．By May，after three months，I had lost 22pounds and reached my goal of 115pounds．My friends would say"Alice，you look great!"or"How did you lose so much weight？"．Those compliments（赞扬）made me feel good and confident．
Soon I dropped to 110ponds．A few of my friends told me that I need to stop dieting because I was starting to look sick．They brought me a present-a bag of chocolates，which I later gave to my sister．My mum would come to my room，with tears in her eyes，and have long chats about how harmful this diet was and begged me to stop．My dad would leave worried messages on my cell phone at school，telling me that it would do serious harm to my body．
By mid-June，when school was coming to an end，I was down to an only alive state of 95pounds．All of a sudden，I knew I had to do something．I guessed the number itself scared me．I recalled my doctor．He told me about a girl who was 95pounds and was at the risk of dying．I knew I was putting my life at risk，but for what？To make those who love me worried？Is it worthwhile to be thin？
Now I realize that models in magazines，TV and movies are not realistic．The price to pay for the"perfect body"is living with the dangerous and sometimes deadly eating disorder．And there are more important things to think about than how thin you are．

19．My first child was due in a couple of months．All of my shopping was done except for one thing．When my little brother was born，my mom had bought an old-fashioned，red-velvet baby carriage（天鹅绒童车）．Ever since then，I wanted one for my child．
I knew that this would be hard to find．So mum offered to take me around．Even used carriages cost quite a bit，and l had only 35to spend．I hoped that I could only use the money I had．Early one Saturday morning，we drove for about an hour to a city with flea （跳蚤）market，and second-hand stores．
As we searched place after place without even seeing a baby carriages，we'd take turns saying，"It
will be at the next stop．"I lost hope as day passed and it was getting dark．I was ready to give up．My mom wanted to go to one more store．One the way Mom told me I should never lost hope．
When we got to the store，I took a deep breath．I knew that this was my last chance．My mom's words began to ring in my ear．"Never lose hope．"As we walked in，l made a quick rush down the middle of the store．There was one new red-velvet baby carriage．I ran over to touch it because I could hardly believe my eyes．
I was so excited that I can't say a word．When I calmed down，it occurred to me that，because it was new，I probably couldn't afford it．The saleslady said it came with the store when she bought it several years ago，and that it had been in storage（储存）until just this morning．She said she wanted to get rid of it as a bargain and was only asking 35．You can imagine how happy we were on our way home．If it hadn't been for my mother，I wouldn't have made it．

6．You can tell a lot about people by looking at their hair-not just whether they brush，spray or blow-dry．Scientists have found a way to use hair to figure out where a person is from and where that person has been．The finding could help solve crimes，among other useful applications．
Water is central to the new technique．The liquid makes up more than half an adult human's body weight．Our bodies break water down into hydrogen（氢） and oxygen．Atoms of these two elements end up in our tissues，fingernails，and hair．
But not all water is the same．Hydrogen and oxygen atoms can vary in how much they weigh．In the case of hydrogen，for example，there are three types according to their weights．Each type is called a hydrogen isotope（同位素）．And depending on where you live，tap water contains different isotopes．
Can hair record this information？That's what James R．Ehleringer，an environmental chemist at the University of Utah，wondered．To find it out，he and his colleagues collected hair from hair stylists in 65cities across the United States．Even though people drink a lot of bottled water these days，the researchers have found that people's hair has the same isotopes as found in local tap water．That's probably because people usually cook their food with the local water．
Authorities can now use the information to analyze hair samples from criminals or crime victims and narrow their search for clues．For example，one hair sample used in Ehleringer's study came from a man who had moved from San Francisco to Salt Lake City．As his hair grew，it reflected his change in location．

28．What do we know about the hydrogen isotopes according to Paragraph 3？B
A．They are classified by size．
B．Each type of them differs in weight．
C．They can improve the quality of tap water．
D．Some of them cannot combine with oxygen．
29．Why is it possible to know where people are from by analyzing their hair？D
A．People use the same bottled water．
B．People wash their hair in different ways．
C．People's hair is affected by the weather of the places they stay．
D．People'hair indicates the type of water in the places they stay．
30．The last paragraph is mainly to showC．
A．how to recognize criminals
B．how to collect hair samples
C．the usefulness of hair analysis
D．the process of Ehleringer's study
31．Which of the following can be the best title for the passage？C
