All that sunlight was fantastic for Moms vegetable garden. Working in the garden at midnight tended to throw her timing off, so she didnt care much about my bedtime.Dad was a Railway Express agent and Mom was his clerk. That left me in a mess. I usually managed to find some trouble to get into. Once I had a little fire going in the dirt basement of a hotel. I had tried to light a barrel（桶）of paint but couldnt really get a good fire going. The smoke got pretty bad, though, and when I made my exit, a crowd and the police were there to greet me. The policemen took my matches and drove me home.Mom and Dad were occupied in the garden and Dad told the police to keep me, and they did! I had a tour of the prison before Mom rescued me. I hadnt turned 5 yet.As I entered kindergarten, the serious cold began to set in. Would it surprise you to know that I soon left part of my tongue on a metal handrail at school?As for Leonhard Seppala, famous as a dog sledder（駕雪橇者）, I think I knew him well because I was taken for a ride with his white dog team one Sunday. At the time I didnt realize what a superstar he was, but I do remember the ride well. I was wrapped（包裹）heavily and well sheltered from the freezing and blowing weather.In 1950, we moved back to Coeur dAlene, but we got one more Alaskan adventure when Leonhard invited us eight years later by paying a visit to Idaho to attend a gathering of former neighbors of Alaska.35.

C 考查判斷推理。根據(jù)文中Working in the garden at midnight tended to throw her timing off, so she didnt care much about my bedtime及Mom and Dad were occupied in the garden and Dad told the police to keep me等話語(yǔ)可以推斷出，作者的父母當(dāng)時(shí)忙于他們自己的事情，無(wú)暇照顧我。36. D 考查細(xì)節(jié)理解。根據(jù)文章第三段話的敘述，I had tried to light a barrel（桶）of paint but couldnt really get a good fire going.The smoke got pretty bad, though, and when I made my exit, a crowd and the police were there to greet me，可知，我點(diǎn)燃了一桶油漆，但火并沒(méi)燃得很大煙卻很濃，警察來(lái)把我?guī)ё?。所以答案選D。37. A 考查判斷推理。根據(jù)倒數(shù)第二段話At the time I didnt realize what a superstar he was, but I do remember the ride well可以推斷Leonhard很擅長(zhǎng)駕雪橇。38.

D 考查細(xì)節(jié)理解。根據(jù)文章第一段及第二段話Izzy, nine,restarted father Colms heart by stamping(踩)on his chest after he fell down at home and stopped breathing可知，女孩的父親因?yàn)閲?yán)重的過(guò)敏反應(yīng)導(dǎo)致心臟驟停，她踩她父親的胸部，目的是讓他父親的心臟重新起搏。40. C 考查細(xì)節(jié)理解。此題考查四個(gè)細(xì)節(jié)的排序。根據(jù)文章的敘述，女孩以前就學(xué)會(huì)了CPR，在父親的心臟停止跳動(dòng)之后，她的母親先撥打了999，女孩發(fā)現(xiàn)自己的手臂力氣不夠用，才用踩她父親胸部的方式。故答案選C。41. A 考查主旨大意。本段描述了女孩的父親Colm星期六因?yàn)椴幻髟虻倪^(guò)敏反應(yīng)被送去醫(yī)院，回家的第二天便發(fā)生了心臟驟停。因此本段是講訴了父親這兩天的遭遇，故選A。42. C 考查判斷推理。通讀文章，可以看出，本文是一篇新聞報(bào)道，報(bào)道了女生在其父親心臟驟停之后的勇敢之舉通過(guò)踩她父親的胸部而挽救了父親，故答案選B。DWith around 100 students scheduled to be in that 9 am Monday morning lecture, it is no surprise that almost 20 people actually make it to the class and only 10 of them are still awake after the first 15 minutes; it is not even a surprise that most of them are still in their pyjamas（睡衣）.Obviously, students are terrible at adjusting their sleep cycles to their daily schedule.All human beings possess a body clock. Along with other alerting（警報(bào)）systems, this governs the sleep/wake cycle and is therefore one of the main processes which govern sleep behaviour. Typically, the preferred sleep/wake cycle is delayed in adolescents, which leads to many students not feeling sleepy until much later in the evenings. This typical sleep pattern is usually referred to as the “night owl” schedule of sleep.This is opposed to the “early bird” schedule, and is a kind of disorder where the individual tends to stay up much past midnight. Such a person has great difficulty in waking up in the mornings. Research suggests that night owls feel most alert and function best in the evenings and at night. Research findings have shown that about 20 percent of people can be classified as “night owls” and only 10 percent can be classified as “early birds”the other 70 percent are in the middle. Although this is clearly not true for all students, for the ones who are true night owls this gives them an excellent excuse for missing their lectures which unfortunately fall before midday.43. What does the author stress in Paragraph 1?A. Many students are absent from class.B. Students are very tired on Monday mornings.C. Students do not adjust their sleep patterns well.D. Students are not well prepared for class on Mondays.44. Which of the following is true according to Paragraph 2?A. Most students prefer to get up late in the morning.B. Students dont sleep well because of alerting systems.C. Ones body clock governs the sleep/wake cycle independently.D. Adolescents delayed sleep/wake cycle isnt the preferred pattern.45. Which of the following is closest in meaning to the underlined word “classified”?A. Criticised. B. Grouped. C. Organised. D. Named.46. What does the text mainly talk about?A. Functions of the body clock.B. The “night owl” phenomenon.C. Human beings sleep behaviour.D. The school schedule of “early bird”.【內(nèi)容要點(diǎn)】這是一篇說(shuō)明文。本文以學(xué)生星期一早上上課時(shí)很多學(xué)生難以將他們的睡眠周期調(diào)整到正常為引子，解釋了“night owl”這一睡眠周期現(xiàn)象。43. C 考查判斷推理。文章開(kāi)頭便舉例在星期一早上的課上只有20%的學(xué)生到，在上課15分鐘后，僅有10%的學(xué)生還醒著，有人還穿著睡衣，而最終歸結(jié)到本段的尾句Obviously, students are terrible at adjusting their sleep cycles to their daily schedule。可知答案為C。44. D 考查判斷推理。根據(jù)文章第二段the preferred sleep/wake cycle is delayed in adolescents（首選的醒睡周期在青少年身上被推遲了）第三段話This is opposed to the “early bird” schedule, and is a kind of disorder where the individual tends to stay up much past midnight可知，這種“night owl”現(xiàn)象是一種紊亂，并不是較優(yōu)的睡眠周期。45. B 考查猜測(cè)詞義。根據(jù)此句語(yǔ)境可知答案：調(diào)查結(jié)果表明大約20%的人可歸類為“貓頭鷹”型，只有10%的人可以歸為“早起”型。此處classify應(yīng)為“歸類，分類，分組”等意思。EWomen are friendly. But men are more competitive. Why? Researchers have found its all down to the hormone oxytocin(荷爾蒙催生素). Although known as the love hormone, it affects the sexes differently.“Women tend to be social in their behavior. They often share with others. But men tend to be competitive. They are trying to improve their social status,” said Professor Ryan.Generally, people believe that the hormone exytocin is let out in our body in various social situations and our body creates a large amount of it during positive social interaction（互動(dòng)）such as falling in love or giving birth.But in a previous experiment Professor Ryan found that the hormone is also let out in our body during negative social interactions such as envy.Further researches showed that in men the hormone oxytocin improves the ability to recognize competitive relationships, but in wo
