Every morning my father buys a newspaper on his way to work.Every evening my mother looks through magazines at home.And every night,I look at the posters with photos of David Beckham and Yao Ming on my bedroom wall before I go to sleep.Can we imagine life without paper or print?

When we got to the hospital, we found Dad still coughed a lot, but his smile was as sure as ever. It was another attack of pneumonia(肺炎).My husband and I stayed with him for the weekend, but we had to go back to our jobs on Monday. Local relatives would help Dad get home from the hospital and look after him. But I wanted to let him know that we also cared about him, even when we weren’t with him.

Then I remembered a family tradition when our children were small. Before leaving their grandparents’ home after a visit, each child would write a love note to their grandparents. For days, their grandparents would smile as they read these notes of love.

So when I cleaned Dad’s kitchen and made the bed for him, I wrote some notes. Some were like this,“Dad, I put the food in the fridge.” Some expressed my love,“Dad, I hope you will sleep well in your new bed.” Most notes were put downstairs where he would stay for several weeks when he was ill. But I put one note upstairs under his pillow (枕头),“Dad, if you have found this note, you must be feeling better. We are so glad!”

These notes helped improve his health. Several weeks later, in one of our regular phone calls, I asked Dad how he was doing. He said, “Pretty good. I just found your note under my pillow upstairs!”

二、16.D 本题考查冠词的用法。句意：“早餐你通常吃什么？”“一片面包和一个鸡蛋。”三餐前不加任何冠词，由此可排除A、C两项；此处数量“一个”用不定冠词表示，egg的读音以元音音素开头，前面应用不定冠词an，再排除B项。故选D。

17.A 本题考查数词的用法。句意：“六班在哪里？”“它在三楼。”“几班”的表达为“Class+基数词”， 由此可排除B、D两项；表示“第几”时用“the+序数词”，再排除C项。故选A。

18.B 本题考查介词的用法。since“自从”；between“在两者之间”；as“作为”；during“在……期间”。由句意“工人们将会在这两座城市之间修建一条新铁路。”可知，此处用between。故选B。

19.C 本题考查代词的用法。invite（邀请）为动词，后面的人称代词应该用宾格，故排除Ａ、Ｂ两项；party（聚会）为名词，前面应该用形容词性物主代词修饰，排除D项。故选C。

20.B 本题考查形容词的比较等级。than前应用比较级，popular的比较级应在前面加more，故选B。

21.C 本题考查动词词义辨析。protect“保护”；produce“生产”；join“加入”；receive“收到”。句意为“去年他加入了一个英语俱乐部并且他的英语提高了很多”。故选C。

24.C 本题考查名词词义辨析。instruction“指令”；description“描述”；collection“收藏品”；expression“表达”。句意：“看看我的邮票。”“它们真漂亮！你得到了一个极好的收藏品。”此处用collection。故选C。

25.D 本题考查非谓语动词。promise to do sth.意为“承诺做某事”。句意：他承诺在他待在天津期间去看他的老朋友。

26.C 本题考查动词的时态。由saw和时间状语yesterday可知第一句为一般过去时态；第二句中at that moment是指“昨天的那个时候”，故应用过去进行时态。句意：我昨天在图书馆看见他了。那时他正在看书。

27.A 本题考查动词短语含义辨析。put on“穿上”；turn on“打开”；put up“举起”；give up“放弃”。由句意“外边很冷，出去之前穿上毛衣。”可知此处用put on。故选A。

28.B 本题考查动词时态。句意：“汤姆在家吗？”“不在，他去镇上了。”应选择B项，表明他去了镇上。have/has gone to去了（某地）。另外注意have/has been to表示“去过（某地）”。

29.A 本题考查连词的用法。when“当……时候”；before“在……之前”；since“既然，自……以来”；although“虽然”。由句意“当我回来时，我发现母亲正在为我做饭。”可知此处用when。故选A。

32.C 本题考查情态动词。needn’t“不必”；must“必须”；might“可能”；mustn’t“禁止，不准”。由“we’re not sure”可知，说话人对他们的安排尚不确定，应用might表示可能性的推测。故选C。

33.A 本题考查宾语从句。由答语中的because可知横线处是询问他离开的原因，故应选用why，排除C、D两项。宾语从句应使用陈述语序，排除B项。故选A。

34.A 本题考查定语从句。句意为“昨天晚上我们看的电影棒极了”。先行词movie为“物”，关系代词应选用that，并在定语从句中作saw的宾语。故选A。

35.D 本题考查情景交际。good luck“祝你好运”；not at all“一点也不”；good idea“好主意”；congratulations“祝贺”。由前句“妈妈，我在摄影比赛中得了一等奖。”可知后句表示祝贺，应选用Congratulations。故选D。

三、36. B chance“机会”，advice“建议”，excuse“借口”，business“商业”。根据文章最后一段的“So my advice is this: If a snake bites you,pick up your phone.”可知选B。

37.A suddenly“突然”，nearly“几乎”，especially“尤其”，fortunately“幸运地”。根据文章叙述，应该是“突然”一条蛇出现了，咬到了杰克逊先生的手。

38.C 通过前文“...Henry Jackson was working in a restaurant kitchen.”可知故事应该是发生在一家饭馆里，所以本题选择restaurant。

39.B 根据文章含义可知应该是这条蛇爬出了箱子然后“藏”在盘子底下，故选择hid（原形hide“隐藏”）。其他三个hung（原形hang“悬挂”），jumped（原形jump“跳”），ran（原形run“跑”）均与文意不符。

40.D under“在……下面”，into“进入”，towards“朝”。不能将蛇扔到厨房下面，故排除under；根据前文我们知道这条蛇本来就在厨房内，所以throw...into“扔进（厨房）”和throw...towards“扔向（厨房）”均不符合逻辑。故只有D符合题意，throw it across the kitchen意为“把它从厨房的这一边扔向那一边”。

41.A stay cool意为“保持冷静”，说的是杰克逊先生保持镇静，用手机给蛇拍了一张照片。其他形容词noisy（吵闹的），pleased（满意的），afraid（害怕的）都与文章前面的anyway（无论如何）不符。

42.C 从前文“bit him on the hand”可知“Soon his hand began to ache...（很快他的手开始疼……）”，所以选hand。

43.D 通过“Doctors couldn’t say what was wrong”和“they didn’t know what kind of snake it was”可知“医生说不清楚状况”的原因是“他们不知道这条蛇的种类”，所以选because。

44.B send sth. to...意为“把某物送/寄到……”，根据文章含义，医生把杰克逊先生拍摄的照片发送到伦敦动物园。

45.C 从全文可知杰克逊先生给大家的建议是如果蛇咬了你，给它拍照。所以本题应用it（蛇）的形容词性物主代词its。

四、46.B 根据文章第一段的My grandfather Jack is 96 years old,and he has had an interesting life.可知，杰克过着有趣的生活。

47.A 根据文章第一段的He says the most beautiful place he has travelled to is Kathmandu in Nepal.可知，他认为最美丽的地方是尼泊尔的加德满都。

48.B 根据文章第二段的Jack has married twice.可知，杰克结过两次婚。

49.C 根据文章第二段的He met his second wife Maria while he was cycling round France.可知，当他骑车环游法国时，他遇到了他的第二任妻子Maria。

50.A 根据文章第三段的He also has a glass of wine every night!可知他每晚都会喝上一杯酒。

51.D 根据文章第一段的And every night,I look at the posters...before I go to sleep.可知，作者在睡觉前会看卧室墙上的海报。故选D。

52.A 根据文章第二段的Paper was first created about 2,000 years ago ...可知，纸张是在大约2 000年前被发明的。故选A。

53.D 根据文章第二段的But in those days,books could only be produced one at a time by hand.可知，书昂贵稀少是由于古代手工技术的限制。故选D。

54.C 根据文章第三段的After that,knowledge and ideas spread quickly.可知，自从书变便宜之后，知识和思想的传播变得迅速。故选C。

55.B 根据文章最后一段的No,I don’t think the Yao Ming poster on my bedroom wall will ever be replaced by a computer two metres high!可推知作者认为书本不会被电脑所取代。故选B。

五、56～60 FADCE

六、61.live on live on 为固定短语，意为“以……为食”。

63.at first at first为固定短语，意为“首先，起初”。

64.go sightseeing go sightseeing为固定短语，意为“去观光”。

65.all over all over the world为固定短语，意为“全世界，遍及世界”。

七、66.ill/sick, hospital 由第一段第一句When we got to the hospital, we found Dad still coughed a lot...（当我们到达医院时，我们发现父亲仍然咳嗽得厉害……）可知，作者的父亲生病，被送去了医院。

67.returned, weekend 由第一段中的My husband and I stayed with him for the weekend, but we had to go back to our jobs on Monday.（我和丈夫与他待了一个周末，但我们在周一不得不回去工作。）可知，作者在与她父亲待了一个周末后回去工作。

68.tradition, notes 由第二段的Then I remembered a family tradition...each child would write a love note to their grandparents.可知，孩子们给他们的外祖父母写充满爱意的纸条是家庭惯例。

69.same,care 由第一段最后一句But I wanted to let him know that we also cared about him...(但我想让他知道我们对他也是关心的……)及第三段...I wrote some notes.可知，作者为了表示对她父亲的关心，做了与她孩子相同的事情（写充满爱意的纸条）。

70.words/answer/reply, better 由第三段中的Dad, if you have found this note, you must be feeling better.及最后一段中的Several weeks later...“Pretty good. I just found your note under my pillow upstairs!”可知，当作者听到她父亲的答复时，她知道他感觉好多了。

八、71.clever 由文章第一句话可知海豚是非常聪颖的。该空上下文都围绕这一内容展开，能体现关键词“聪颖”之意、且以字母c开头的单词为clever。

72.similar 空前dolphin intelligence和空后human intelligence是两者的比较，结合下文like humans可知，两者为相似关系，再结合固定搭配be similar to可知应填similar。

73.It 结合句意可知此处应填入一个代词代指前文的name，根据首字母I可以得出答案为It。

74.talk 该句为主从复合句，dolphins, like people,“t________” to each other...为该句的宾语从句，根据句子结构可判断该词是谓语动词，结合下文中的body language，conversations等以及talk to的搭配可知答案为talk。

75.communicate 该句所包含的固定搭配是use sth. to do，其中to do表示目的，由该句可推知，海豚使用声音系统和肢体语言的目的是“交流”，故填communicate。

76.fun and前后内容应意思相近、形式一致，由and前的come to play games可推知其后应为have fun，故填fun。

77.together 由In fact（实际上）可知句子主语“playing t________”所指应为前文内容，结合前文...come to play games from different groups（来自不同群体的海豚来玩游戏）可判断主语应为playing together，故填together。

78.both 该句位于段首，为主旨句，总结全段才能明确该句意思。由下文可知，海豚会帮助人类实施捕鱼计划，即海豚和人类都会计划。两者都会，结合首字母b可得出答案为both。

79.near 后文提到海豚给渔民发出撒网信号，渔民因此捕到很多鱼。由常识可知，撒网捕鱼应该在鱼群靠近船的时候，故答案为near。

80.help 根据上文海豚向渔民发出撒网信号可知，海豚是在帮助渔民捕鱼，故此空填help。

九、One possible version:

Last Saturday evening, all my family had dinner in a restaurant. We enjoyed ourselves while we were at table. However, some teenagers sitting beside our table began to talk and laugh loudly. What’s worse, they began to smoke in the restaurant, which made us angry. After a while, I stood up and advised them to stop smoking and behave themselves. To my surprise, they didn’t follow my suggestions. Instead, they laughed at me, saying that I was too young and too naive.

In my opinion, it’s wrong to do that in public. The future of Tianjin lies in teenagers, who should not only obey the rules in public but also make contributions to the society.
