Back in high s chool in Chicago, Sue Napolitano and Larry McNevin were just friends. They wore jackets and were always sitting on the bridge smoking. But neither gave the other a romantic thought. In fact, asked to describe each other back in those days, Sue and Larry bo th came up with the adjective: “nice”.On Sept. 11, 2004, after 35 years, the high school friends were about to find out how nice “nice” could be. Larry was looking for another friend with whom he went to high school through , a service that reconnects high school friends through e-mails. That friend suggested he call Sue.Then Larry and Sue talked from the topics of music to food and found they shared similar tastes. After that, they both ran to their closets to dig out their yearbooks t o find the other‟s picture.With that one call, Sue, who divorced (离婚) in 1985 after five years of marriage, and Larry, who divorced in 1997, began calling and e-mailing each other daily. A month later Sue flew to Chicago. Larry and Sue hugged and cried when they met at the airport. They were like two lovers separated for years.On April 11, 2005, while the two were in Las Vegas, they got married. After the wedding, Larry said it made more sense for him to move to Phoenix, since he planned on retiring to someplace warm, and few places are warmer. They now live in Phoenix and are surprised how high school friends found their way back together after 35 years.36. When Sue and Larry were in high school, _______.A. Sue was Larry‟s girlfriendB. they felt it was nice to stay togetherC. they both liked lifetime TV moviesD. they always had romantic ideas with each other37. On Sept. 11, 2004, Larry was surfing at Classmates. com. with the purpose to ________.A. search for his girlfriendB. look for how to reconnect SueC. seek advice about marriageD. search for another schoolmate38. According to the passage, the climate in Phoenix is probably _______.A. coldB. warmC. wetD. dry39. After so many years, Sue and Larry got married, which they both felt ________.A. amusingB. foreseeableC. amazingD. impossibleBPeople today, in all this new world technology and thinking, have lost sight of what a true friendship is. I thought I would help the world out a little and explain what real, true friends are.1. Friends don‟t have to be exactly the same. Friends have similarities but they also have their differences. The key to opening up the world of friendship is not only to expand on similarities but to accept each oth er‟s faults. Because you can‟t ever judge your friend.2. Friends have to argue! No one likes to but it is necessary.3. You have to be comfortable together. Otherwise, you just aren‟t going to click. If you feel uneasy around the person then something isn‟t quite right.4. Friends love unconditionally. They have their little angry moments but what‟s done is done and all is forgiven and forgotten. Why let something that happened in the past ruin the happiness you could have in the future?5. Believe in love at first sight because there is the same thing happening in friendship. Some people think that you have to know someone really well to become good friends. Trust me, it‟s not true.These are only a few of the basics. Just remember, friends are forever. But only if you keep it that way. Don‟t disrespect your friends, love them instead.40. According to the writer, friends can be made _______.A. only when there‟s no difference between the two peopleB. only when the two people get to know each other very wellC. shortly after the two people met sometimesD. simply by forgetting the two people‟s past41. The underlined sentence means that _______.A. you will feel angryB. you can‟t be friendsC. you can‟t be com fortableD. you shouldn‟t drop him / her a line42. In the writer‟s opinion, true friends ________.A. must be similar to each otherB. do not argueC. must be honestD. must always love each other43. Which of the following is the best title for the passage?A. True Friends.B. Love Your FriendsC. How to Make FriendsD. Friends Are ForeverCDear Jewel,I’m not exactly shy, but I always avoid making friendships with people. I have two close friends whom I contact occasionally (偶尔) and I want to have more, but sometimes I think I’m just too much of a loner. I didn’t really make any close friends in my four-year-long university. The one or two friends I did make, but I didn‟t put any effort into keeping in touch with them and we lost touch. I often find myself alone on weekends. But I keep up with music and fashion. Once in a while, cool people have tried to become friends with me, but I always finally pull away. Do you think it‟s strange to be a loner? Should I try to change my life? How can I do that?—ALONE AS ALWAYSDear A.A.A,Do I think you’re “strange”because you’re a “loner”? No, I think you’re just human. Would I encourage you to live a life of solitude (孤单)? No, of course not. Life is all about growth, reflection (反省) and socialization. Relaxing alone once in a while is totally cool. However, leaving completely from your social scene isn‟t healthy.It leads to a lonely existence. Now, it‟s time to take action. Try to pick up the phone and call good friends. Chances are they will be happy to hear from you. Want to enlarge your social circle? V olunteer (自愿) for a good cause. Take general interest courses. Get off your couch and take a dance class or join an amateur (业余的) sports team.Get stuck when chatting with people? Plan what you want to say in advance. List conversationtopics that‟ll get people talking. Learn to ask open-ended and follow-up questions.Most importantly, have some confidence. Know your strengths. Know your weaknesses. Work on becoming an interesting person to meet.Best of luck.Jewel44.

Which advise did Jewel not offer?A. Call good friends.B. Enlarge social circle.C. Travel with parents.D. Have confidence.46. According to the second letter, Jewel thought that______.A. life should not be total solitudeB. loners aren‟t healthy in maint aining relations with othersC. being lonely often is completely coolD. A.A.A. should catch up with fashion47. After reading the letter from Jewel, ALONE AS ALWAYS will probably be ______.A. more lonelyB. disappointedC. doubtfulD. satisfiedDThere’s a new zoo in Louisiana, US, which has many of the usual attractions. Like most zoos, its goal is to protect wild animals and educate the public. However, the Louisiana Audubon Nature Center is more than a wildlife center. It has a planetarium (天文馆), a forest, and a special frozen zoo that rarely has visitors.Saving species from dying out is the main goal of the Nature Center. Tourists visit the public areas of the Nature Center. But scientists work behind the public areas. They use the place to prevent animals dying out. They hope that the frozen zoo will one day be able to save and keep allthe animals alive on our planet. In the frozen zoo, there aren’t any live animals in cages. Instead, it has live cells in tiny building blocks of the animals—in liquid nitrogen (氮) bottles. Liquid nitrogen is very cold and it keeps the cells perfect, so the cells should be safe for hundreds of years. The frozen zoo has over 1,000 different species that are put in nitrogen. If one of these species becomes endangered, the scientists can unfreeze the cells and bring the species back.Many animals are struggling to survive. But their future is not that worrying, because there are more and more zoos joining the frozen zoo project. And scientists are also working to save habitats (the places where animals live and plants grow). Hopefully we will be able to save all species from dying out and give them a safe place to live.48.

It takes a lot of people to decide.1) If a country wants one of its places to be on the World Heritage List, it has to ask UNESCO(联合国教科文组织). The place must be important and special. UNESCO put the Great Wall on the list in 1987 because it said it was a great part of Chinese culture and beautifully made to go with the land. When a country asks, it must also make a plan for taking care of the place.2) The World Heritage Committee of UNESCO talks about different places and decides whether to put them on the list. The committee meet every June. Many experts help the committee to decide.3) After a new place goes on the list, UNESCO gives money to help keep it looking good. If a place is in serious danger, it may be put on the List of World Heritage Sites in Danger. UNESCO gives special care and help to those places.4) Countries have to give UNESCO regular reports about places on the list. If UNESCO thinksa country isn‟t taking good care of a place, the site will be taken off the list.52.
