11．Before accepting a job offer，you should consider seriously （61）whether/if the job is really what you want to do．Why are you interested in this position？
The reasons for （62）taking（take） a job mainly depend on your desires and your ability．It may be okay to take a job that is not something you（63）really（real） want to do right now，if it allows you to get into a （64）better（good） position in the future．
Furthermore，you should consider the company （65）which/that offers you the position．Is it a good company（66）to work（work） for？Do they share your values？If not，does this matter （67）to you？
One of the most （68）satisfying（satisfy） parts of a job for many people is that the job （69）challenges（challenge） them．It allows them to think and focus on （70）problems（problem）．It's more than just a desk job．

10．Last week I went to visit my former neighbor，Mr．Yang．He and I used tolivenext to each other for many years．About half a year ago，an order came that the old building，with many othersimilar相似的） ones，should be pulled down to make room for a main street．So we had to move apart．Mr．Yang hassettled（定居） in the suburbs near a beautiful park．His apartment is much larger than before．The only problem is that ittakes quite a long time to get to the downtown area．However，Mr．Yang doesn't seem to worry about the longdistance（距離）．He says that a new subway line will be built in a fewyears，whichmeans life will certainly be more convenient in the future．

9．Festivals and celebrations of all kinds have been held everywhere（91）sinceancient times．Today's festivals have many（92）origins，some religious，some seasonal，and some for special people or events．In Mexico，people celebrate the Day of the Dead in early November．On this important feast day，people eat food in the shape of skulls and cakes （93）with"bones"on them．In the USA，Columbus Day is in memory of the（94）arrivalof Christopher Columbus in the New World．Harvest and Thanksgiving festivals are happy events because the food is（95）gatheredfor the winter and a season of agricultural work is over．The most（96）energeticand important festivals are the ones（97）that look forward to the end of winter and the coming of spring，such as the Spring Festival in China．
Wang Peng sat in his empty restauran（98）feelingvery frustrated．Suddenl y he saw his friend Li Chang  （99）hurrying（100）by．But Li Chang （101）seemednot to hear his greetings．Something terrible must have happened if Li Chang was not coming to eat in his restaurant（102）as he always did．Wang Peng followed Li Chang into a new small restaurant．（103）Curiosity drove Wang Peng inside．What amazed him was that the food there cost more than that in his own restaurant．After doing some research，he wrote his own sign to（104）win his customers （105）back．

8．Last week，I went shopping for the items I needed（61）formy voluntary work of cooking breakfast on Saturday at a shelter for the（62）homeless （home） in San Jose，California．I went to a store （63）to buy（buy） some tofu and vegetables．As I（64）was waiting （wait） in line to finish the shopping，the lady next to me approached （走近） me to find out （65）how I was going to consume （吃）such  a big box of tofu I was buying．I told her that I was buying food to cook breakfast for those people in the shelter．While I was getting ready to pay the bill，to my（66）amazement （amaze），she offered to pay for everything without saying（67）her name．She said that she felt good because I was doing the kind of community work from which her parents once received help （68）when/as they came to this country as refugees （難民）．So she wanted to take this opportunity to show her gratitude．
It was the（69）best （good） reward I had ever received for my voluntary work，（70）whichbegan three years ago．In a strange way we are all connected and we feel grateful for each other．

7．Giving hong bao，or red packets，during the Spring Festival or other important occasions is a long Chinese tradition．A red packet，usually a red envelope with money in it，（61）which is traditionally given out to children by relatives or friends，is a way of wishing them good luck or good fortune．According to the Internet，（62）compared（compare） with the fat hong bao children got in previous years，red envelopes during this Spring Festival became fewer and （63）thinner（thin）．For those children who had got a lot of money from their red envelopes in the past，the slim red packets they （64）received（receive） this year might have led to their complaints （65）and/or/which/that made them quite disappointed during the festival．However，fewer red packets stand for a positive social trend and this is just （66）what sociologists thought should be encouraged．（67）Handing/To hand（hand） out red packets is a kind of expression of love to children，regardless of how much money （68）they contain．With a large amount of lucky money during the Spring Festival，some children become moneybags over one night．Too much money won't be beneficial for children to make a wise choice （69）between saving and spending．In this reason，it is necessary （70）to change（change） the way to express our feelings．

6．It was a summer afternoon and some boys were playing together in a park．They knew each other well，（56）asthey had spent the last three years of school together and tomorrow was the start of a new term，about（57）whichthey were excited and nervous．
The first day of school came，and all the boys from the park the day before were put in the same class（58）by coincidence．They jumped for joy all morning long．After lunch，the teacher came into the classroom with a boy and it was evident（59）thatthey had never seen him before．
All the children were quiet，（60）waiting（wait） for the teacher to speak．And she said："Hello everyone，this is Mei Pei from China，our newest class member．Mei Pei knows some English so I hope you will treat him as if he（61）were（be） your brother．"
Then one child said to Mei Pei："How come you speak（62）differently（different）？"Mei Pei answered："In（63）mycountry，we all talk this way．On the other hand，we're just the same as you．I wish I could speak English as well as you ill three months．"
The children in the class（64）understood（understand） this，and that it also didn't matter what he looked like，or what colour his skin was，or that he didn't speak perfect English．
So the new（65）addition（add） to the class helped everyone learn how to respect new people．And the boys stayed in the same class for another two years，with Mei Pei as one of their best friends．

5．Laura went to the stable（馬廄）．Four horses stood there．She put a saddle on Star，a big and brown horse．Her sister，Janice，（41）chose（choose） Moon，a white horse．They were both going to exercise the horses．
It was a（42）sunny（sun） day．They got on the horses and started walking（43）them（they）．Some minutes later，Laura was telling Janice about the doctor（44）who/thatwas new to her hospital．She raised her hand for（45）asecond to speak．Just then，Star bucked．Laura went flying into the air．She landed on her head and shoulder on the grass．
"Oh，my God!"Janice cried，"Laura，are you all right？"Janice（46）gently（gentle） rolled her over．She didn't see any blood．"That's good，"she thought
"Can you move？You're not paralyzed（癱瘓的）anywhere，are you？"Janice pulled Laura up into a sitting position．Laura slightly moved her legs and（47）arms（arm）．When she moved her right hand to touch her head，she groaned（呻吟）．
Janice asked Laura（48）whatwas the matter．"When I moved my arm，it hurt．"Laura answered．They still didn't see any blood．Janice unbuttoned Laura's blouse（49）andlooked at her right collarbone．"Oh，no，"Janice shouted，"You're seriously （50）injured（injure）．"And then she sent Laura to the new doctor as soon as possible．

4．Polar bears live in environments too cold for most（41）animals（animal）．For much of the year，they live and hunt on the （42）frozen（freeze） Arctic sea ice．Nature has prepared them for the cold conditions．But nothing has prepared the bears for the danger（43）that/whichthreatens the only home they know．
The polar bears'world is melting．Studies show that the polar ice（44）has reduced（reduce） by 9.8% every 10 years since l978．Now about 20，000 to 25，000 polar bears live in the Arctic．Polar bears depend on the sea ice for their（45）survival（survive）．"The sea ice is more（46）thanjust this platform that the bears walk over，"says Andrew Derocher，a scientist who studies North American polar bear populations．"Without（47）it，they can't exist．"
Some melting and refreezing of the polar ice is（48）natural（nature）．But in a warmer world，these cycles speed up，and bears have（49）less（little） time to hunt．Normally，they have three months in the spring when they gain more weight．The extra fat is used（50）later（late），when the bears are not actively hunting．
