7、The findings are the first to show in humans how keeping fit affects the ageing process.The study of 2,401 twins found that a sedentary (惯于久坐的) lifestyle raises the risk of a range of problems from heart disease to cancer and appears to play a key role in the ageing process.It all appears to boil_do

15、r telomeres one has，the more slowly one gets old1Without knowing the language，it is very difficult for the stranger to understand the people of the country and their customs.(完形填空第一段)如果不懂(这一国家的)语言，对一位陌生人来说要理解这个国家的人们和风俗习惯是很难的。(1)It is difficult for you to pass the College Entrance Examinations if you
16、 dont study hard.如果你不努力学习，是很难通过高考的。(2)It is necessary for everyone to learn a skill for life.对每个人来说，为了生活学习一门技术是有必要的。2It all appears to boil down to the length of structures called telomeres.(阅读理解第四段)所有这些问题似乎都归结于一种叫做“端粒”的长度(1)It appears that there has been a change in the plans.计划好像作了修改。(2)The boys a
17、re completely innocent?So it would appear from the press reports.这些孩子完全是无辜的？从新闻报道看好像是的。3The reason why exercise has this effect is not clear.(阅读理解最后一段)运动为什么有这样的效果其原因不清楚(1)The reason why he was late this morning is the heavy traffic.今天早晨他迟到的原因是由于交通堵塞。(2)The reason why she brought up what she had eate
18、n was that she was ill.她把吃的东西都吐了，原因是她病了。答案.1.A根据文中第一句大意可知。2Canyone用于肯定句时，意为“任何人”。3Benough修饰interested；enough修饰形容词时，必须放在它所修饰的形容词之后。4B要去一个国家旅游，就应该学习该国语言，以便能够与那里的人们进行交流。5C句中but表示转折，暗示“学习某种语言很难，但对在该国旅游的好处是显而易见的”。6Dsuch an effort意为“这一努力”。7A掌握该国语言的好处只有在到达该国之后才能体现出来。8D根据句意可知，it指“掌握外语”，要是待在家里，学习外语的重要性根本体现不出
19、来。9Chow表示方式。10A对于一个到外国旅游的人来说，如果语言不通就无法订饭、租房，因此知道如何订饭、租房是必要的。11Dstrange陌生的。12B把四个答案进行对比，只有knowing意义符合上下文。13D只有very才符合上下文大意。14B此处是指理解这个国家的人。15D根据生活常识判断，出国旅游见到熟人时，往往会说“这世界真小”。16D该段从另一方面说明懂外语的重要性。本句讲即使在国外能遇到懂自己语言的人，也不如自己懂外语方便。17B不懂外国的语言，也能看见各个地方和各种事物，see意为“看见”。18Ause表示的意义最为全面。19Cheart在这里表示一个国家的内涵或核心。20B
20、进一步强调懂得外语确实很重要。.1.C标题判断题。综观全文可以看出，文章第一段向我们讲述了一项研究结果：锻炼身体是永葆青春的秘诀。下文进一步解释了该项研究的具体细节和成果，因此Exercise keeps you younger(多锻炼让你青春永驻)就是该文的标题。2C细节理解题。文章第三段告诉我们：久坐的生活习惯不但会加大患心脏病和癌症等一系列疾病的风险，而且是影响衰老进程的关键因素。也就是说：久坐的人容易生病(are inclined to be taken ill)。3A词义猜测题。该段是对上文研究中发现“久坐的生活习惯不但会加大患心脏病和癌症等一系列疾病的风险，而且是影响衰老进程”原因的分析，本句意思是“所有这些问题似乎都归结于一种叫做端粒的长度”。由此可以看出：boil down to意思是“在于，归结于”。4B细节判断题。由倒数第四段可判断，B项错误，C项正确；由第五段的第一句“. telomeres get shorter over time”可以判断A项正确；由倒数第二段可以看出D项正确。5D推理判断题。由第五段的“.telomeres get shorter over time，suggesting the cells are ageing or dying”可以推出：一个人拥有的端粒越长，衰老得就越慢。
