20、to.After that Christmas,David and I became good friends and I never forgot the meaning _20_the little empty box set on my desk.1A.anxious B. courageousC. serious Dcautious解析anxious“焦急的;急切的”;上文中提到虽然才十月份,学生们已经私下讨论圣诞节的计划了,所以学生们应该是焦急地等着最后的铃声。答案A2A.warning BringingC. calling D. yelling 解析句子“Upon its”中its

21、指的是上文中的school bell,所以只能和ring搭配。warn“警告”;call“打电话”;yell“喊;叫”。答案B3A.scolded BwonderedC. realized Dlearned解析wonder“想知道;纳闷”。大卫穿得很破,“我”很想知道他的家庭生活是什么样子。scold“责骂”;realize“意识到”;learn“得知”。答案B4A.modestly BnaturallyC. inaccurately D. inappropriately解析inappropriately“不适当地;不适合地”。根据下文中的the cold winter months,with

22、out a coat,boots,or gloves可知大卫穿得不合时宜。modestly“谦虚地”;naturally“自然地”;inaccurately“不精确地;有错误地”。答案D5A.popular B. upsetC. special Dfunny解析special“特殊的;特别的”。上文中提到大卫穿得不好,下文中提到“我”能记得的是大卫脸上一直挂着微笑,总是乐于助人,说明他与众不同。popular“深受喜欢的;流行的”;upset“情绪低落的;不安的”;funny“滑稽可笑的”。答案C6A.expressing BdeliveringCwearing D. sharing解析wea

23、r“呈现;显现;脸上露出(某种神态)”,wear a smile“面带微笑”。express“表达”;deliver“传递;递送”;share“分享”。答案C7A.practised BwanderedC. studied Dstayed解析stay“留下”,stay after school“放学后留下来”。上文中提到大卫乐于助人,所以此处表示大卫放学后总是留下来摆齐凳子,拖地。practise“练习”;wander“闲逛”;study“学习”。答案D8A.would B. shouldCmight Dcould解析would“老是;总是”。我们说话不多,但他总是微笑着并且问还能干什么。sh

24、ould“应该”;might“可能”;could“能够”。答案A9A.aim at Bturn toCput off D. head for 解析head for“朝进发;前进”。大卫打扫完教室,感谢我留下他,然后就回家了。aim at“瞄准”;turn to“转向”;put off“推迟”。答案D10A.argument BexcitementCmovement D. judgment解析excitement“兴奋;激动”。上文中提到学生十月份就焦急地等待着圣诞节的到来,到放假前的那天,期待圣诞节到来的“兴奋”之情已经变成了不安。argument“争论”;movement“运动”;judgm

25、ent“判断力,识别”。答案B11A.school B. yearCeducation Dprogram解析下文中before the holiday break“放假前”,显然说明应该是school day。其余三项都不符合上下文的语境。答案A12A.relief BreturnC. vain Dcontrol解析relief“轻松;宽慰”,in relief“轻松地;宽慰地”。当所有的学生走出教室后,“我”宽慰地笑了。in return“作为回报”;in vain“徒劳”;in control“控制住”。答案A13A.weakly BsadlyCquietly Dhelplessly解析q

26、uietly“静静地”。从上文中可知大卫不像其他人那样激动,他只是微笑,说话不多,所以此处应是大卫静静地站在讲桌旁。weakly“虚弱地”;sadly“难过地”;helplessly“无助地”。答案C14A.searched B. foundC. raised D. pulled解析pull“拽;拉”。大卫说他有东西给老师,此处应该是大卫从身后把那个盒子拉出来。search“寻找”;find“找到;发现”;raise“举起;抬起”。答案D15A.Holding B. HandingCSending D. Leaving解析hand sth.to sb.“把交给某人”。大卫把盒子交给了“我”,并

27、急切地让“我”打开它。hold“拿着;握着”;send“送;寄”;leave“把留给”。答案B16A.delight B. expectationC. appreciation D. surprise解析surprise“吃惊;惊讶”。送给别人礼物,盒子里应该有东西,而老师打开盒子后发现盒子是空的,所以应该感到惊讶。delight“高兴”;expectation“企盼”;appreciation“感谢”。 答案D17A.cheap BemptyC. useless D. improper解析empty“空的”。由上文中的saw nothing和下文中的Its full of love,可知B项

28、正确。improper“不合适的”。答案B18A.as BuntilC. because Dthough解析as“当的时候”,引导时间状语从句。老师听了大卫的话后被感动了,看着这个平时自己不太关心的孩子,老师眼里充满了眼泪。until“直到”;because“因为”;though“虽然”。答案A19A.advice B. supportC. attention Dcommand解析attention“留心;注意;关心”。从上文中的We never talked much可知,作者对大卫没有注意(关心)太多。advice“建议”;support“支持”;command“命令”。答案C20A.fr

29、om B. behindCover Dtowards解析behind“在后面”。由整篇文章可知,空盒子背后的意义令作者终身难忘。答案B.阅读理解Food sometimes gets poisoned with harmful things.A person who eats such food can get an illness called food poisoning.Food poisoning is usually not serious,but some types are deadly.The symptoms of food poisoning usually begin w

33、is means that people should never touch food with dirty hands or put food on unwashed surfaces.Food should be kept in a refrigerator to stop microorganisms from growing.Meat needs to be cooked thoroughly to kill any dangerous microorganisms.People should also wash food covered with chemicals before

34、eating it.Finally,people should not eat wild mushrooms or other foods that grow in the wild.Some of these foods may contain natural materials that are poisonous to humans.In addition,some types of fish can be poisonous. Most people recover from food poisoning after a few days of resting and drinking

35、 extra water.If people eat natural poisons,they must go to the hospital right away to have their stomachs emptied.1Which of the following statements is NOT true?AFood when poisoned can make people sick.BFood poisoning means death.CFood poisoning comes in varieties.DFood poisoning can be serious.解析细节

36、理解题。根据第一段第三句“Food poisoning is usually not serious,but some types are deadly.”可知选项B“食物中毒就意味着死亡”是错误的,因此选项B为本题的正确答案。答案B2We know from the passage that the symptoms of food poisoning _.Aare always accompanied by a feverBare too common to be notedCcan be noticed within hoursDcan be ignored解析细节理解题。根据第一段的倒

37、数第二句话“The symptoms of food poisoning usually begin within hours of eating the poisoned food.”可知在食物中毒的数小时内便会出现中毒症状,所以选项C正确。答案C3Food poisoning can be caused by all the following EXCEPT _.Asome chemicals Blow temperaturesCsome tiny living thingsDcertain natural materials解析细节理解题。根据第五段第四句“Food should be

38、kept in a refrigerator to stop microorganisms from growing.”可知冰箱里的温度即低温会阻止微生物的生长,因此不可能是导致食物中毒的原因之一。所以选项B正确。答案B4From Paragraph 5,we can learn that _.Amushrooms should not be eatenBvegetables are safer than meat and seafoodCnatural poisons are more dangerous than chemicalsDdifferent types of food should be handled differently解析细节理解题。根据第五段,选项A说蘑菇不能吃,而文中是说野蘑菇不能被食用,所以错误;选项B在文中未被提到;选项C说由于吃了本身有毒的食物而中的毒比化学物质导致的中毒更严重,这一点在第五段也没有提到;所以选项D说不同类型的食物应该用不同方法处理,是正确的答案。答案D
