【文章內容簡介】 選A。 （3）考查詞義猜測。根據(jù)最后一段中的“Mr. Coker says it also has a parachute (降落傘) that can be used should there be an emergency. It starts to work at very low altitude …., ”Coker先生說Jetpack上也有降落傘，可以在緊急情況下使用?！霸诤０畏浅５偷那闆r下開始用它…”?？芍?，Jetpack上的降落傘（它）是在海拔低時才用。由此可知it指的是parachute (降落傘)。故選D。 （4）考查主旨大意。根據(jù)第一段可知，許多人一直夢想能像騎自行車一樣簡單的飛來飛去，科技的發(fā)展讓這個夢想很快實現(xiàn)。然而飛行自行車的安全性和強度一直是個大問題。接著下面敘述了兩家研發(fā)飛行器的公司的最新的產(chǎn)品，新產(chǎn)品把安全放在首位。故選B。 【點評】本題考點涉及細節(jié)理解，推理判斷和主旨大意三個題型的考查，是一篇科研類閱讀，要求考生在捕捉細節(jié)信息的基礎上，進一步根據(jù)上下文的邏輯關系，進行分析，推理，概括和歸納，從而選出正確答案。5．閱讀理解 When a dog looks at you with big puppydog eyes, it39。s hard for you to go away, and you may speak out “A” without hesitation. However, there39。s a reason why you find a dogs stare so attractive. That sweet stare actually causes the release of a particular hormone, or chemical messenger in the body. This hormone creates feelings of affection in humans. The same thing happens to dogs when people look back at them. Scientists believe this helps people and their fourlegged friends bond, or feel connected. Scientists have wondered what causes dogs to lovingly stare at their owners. To find out, a team of researchers from Azabu University in Japan studied 30 owners and their dogs. The researchers found that after the pets and their owners spent half an hour together, both showed a rise in oxytocin (催產(chǎn)素). One key role of this hormone in many animals is to promote bonding, like that between a mother and newborn. The increase of oxytocin didn39。t happen, though, when scientists repeated the experiment with wolves and the humans who had raised them. A second experiment also found that if dogs were given oxytocin, they looked at their owners longer. Scientists aren39。t sure exactly why, but this reaction occurred only with female dogs. Their owners oxytocin levels also rose as a result. The result of these experiments might help answer an ageold question: How did the fearsome wolf ancestor of modern dogs turn into man39。s best friend? Takefumi Kikusui, an animal scientist who worked on the study, thinks that the change happened when dogs first became domestic (馴養(yǎng)的). According to Kikusui, there may have been a small group of wild dogs that were naturally friendlier. “Humans are very sensitive to eye contact. By using this special munication tool, the dogs are able to win over our hearts. If they are more likely to make eye contact, it would be easier for them to bond with dog owners,” Kikusui said.（1）According to Paragraph 1, people say “A” to .

However, there39。s a reason why you find a dogs stare so ，你毫不猶豫地說“A”，不愿意離開。這是因為你覺得狗的注意力很有吸引力，狗吸引了你，說明你愛狗。故答案選B。（2）細節(jié)理解題。根據(jù)第二段開頭的…after the pets and their owners spent half an hour together, both showed a rise in oxytocin (催產(chǎn)素). One key role of this hormone in many animals is to promote bonding, …寵物和主人在一起半個小時，人與狗身上的催產(chǎn)素就會增加了。這種激素在許多動物中的關鍵作用就是促進關系。說明，催產(chǎn)系可以幫助動物加強聯(lián)系，提升關系。故答案選C。（3）推理判斷題。第三、四兩段給狗催產(chǎn)素，它們注視主人時間更長。但是只有母狗會如此，所以給狗催產(chǎn)素后，狗的反應不一樣。這些實驗的結果可能有助于解決一個古老的問題：現(xiàn)代狗的可怕狼祖先是如何變成人類最好的朋友的？從事這項研究的動物科學家Takefumi Kikusui認為，這種變化就是狗最初成為家畜時發(fā)生的變化。由此可推斷出，這種變化就是狗由令人害怕的狼祖先變成人類最好的朋友。分析選項可知，故答案選A。（4）主旨大意題。通讀全文可知，本文解釋了狗與人類的關系如何演變成今天的如此和諧的朋友關系的原因。分析選項可知D項（解釋人類和狗連系的原因）符合題意，故答案選D?！军c評】閱讀理解題主旨大意及段落大意解題技巧：位于段首：一般而言，以演繹法撰寫的文章，主題句往往在文章的開頭，即先點出主題，然后圍繞這一主題作具體的陳述。位于段尾：有些文章會在開頭列舉事實, 然后通過論證闡述作者的核心論點。位于段中：有時段落是先介紹背景和細節(jié)，接著用一句綜合或概括性的話概括前面所說的內容或事例，然后再圍繞主題展開對有關問題的深入討論。首尾呼應：主題句在段落的開頭和結尾兩個位置上先后出現(xiàn)，形成前呼后應的格局。6．閱讀理解 Two heads are better than one. It means that two people working together have a better chance of solving a problem than one person alone. But not everyone likes working in a group. There can be a number of reasons why people dislike group work. Some may feel nervous or uneasy in group situations. Others might have had a bad experience with individuals who did not work well as a team. Another ment is that teachers or instructors fail to provide roles for group members. This may create a situation where everyone or no one wants to lead. Whatever the issue, the result is the same: the group does not realize its goal. Cooperative (合作的) learning is an educational method that can help to solve this problem. There are many methods of cooperative learning. Today we will talk about one: giving each person in a small group a specific duty to reach a shared goal. For example, if learners are divided into groups of four people each, their roles might be: leader, writer, checker and speaker. This structure helps ensure that everyone takes part equally in group work and allows each member to play a meaningful part in pleting the shared goal. Before dividing learners into groups, it is a good idea for the teacher or club39。s instructor to first have knowledge about the language skill levels of participants. The goal is to make each group a mixture of higher and lowerlevel language learners. Putting too many people with similar skill levels together could
