And it just may provide a little extra protection to everyone39。故選C。根據第三段中的“If you are truly in danger, these hormones can help you.”如果你真的有危險，這些荷爾蒙會幫助你。故選D。釋放出的化學物質更積極。 （1）考查細節(jié)理解。s opinion? has the same effects as laughter. can be used to take the place of medicine. is better than any healthy lifestyle to health. can make our body produce beneficial chemicals.（2）What can we know about the mentioned stress hormones? can lower our blood pressure. will surely lead to heart diseases. can benefit us when we are in danger. will make us live an unhealthy lifestyle.（3）Why does Dr. Chockalingam think smiling is helpful to our health? can make us relax. increases sugar levels. has little bad side effects. can happen for no reason.（4）What can be the best title for the text? Thorough Analysis of the Causes of Heart Diseases Thing You Can Do Right Now to Help Your Heart Thing That Is Closely Connected with Stress Hormones Clear Connection Between Unhealthy Lifestyles and Heart Diseases【答案】 （1）D（2）C（3）A（4）B 【解析】【分析】本文是一篇說明文，哥倫比亞的心臟病專家Chockalingam博士建議多保持微笑，他認為微笑可能是幫助心臟的一種方式。Once people smile, they are relaxing. This relaxation directly lowers blood pressure, improves sugar levels in the blood. If we are smiling, we are breaking that link between stress and health. And it just may provide a little extra protection to everyone39。 Researchers say the connection between stress and heart disease is still unclear. However, they claim that when people are stressed for long periods of time, they may have an unhealthy lifestyle, which can lead to health problems. s main stress hormone. It increases sugar in the bloodstream. If you are truly in danger, these hormones can help you. They are part of what we call our fightorflight response. Dr. Chockalingam, a heart disease specialist in Columbia, advises his patients to smile. He says a smile may be one way to help your heart. When we smile, the brain wiring changes. The chemicals that are released are more positive. He says smiling is the first step in fighting physical and emotional stress and its sometimes harmful effects on human health. This is not just New Age advice. Several studies support his opinion. 4．閱讀理解 故選D。所以短文主要是圍繞著海洋氧含量下降而展開的。 （4）考查主旨大意。故判斷出海洋脫氧改變了一些動物的自然領地。這些調整可能使動物暴露在新的掠食者面前，或迫使它們進入食物匱乏的地區(qū)。 （3）考查推理判斷。所以表面的極地冰水阻止氧氣下沉是海洋缺氧的原因之一。這個過程會形成一種冰蓋，它可以防止水流將地表水混合到海洋更深的深度。 （2）考查細節(jié)理解。所以根據前兩段，科學家最擔心的是變暖的海洋中日益惡化的脫氧現(xiàn)象。一些最近的研究表明，在過去的50年里，一些熱帶地區(qū)的氧氣含量下降了驚人的40%。 （1）考查細節(jié)理解。The Ocean Is Running Out of Breath【答案】 （1）A（2）C（3）A（4）D 【解析】【分析】本文是一篇說明文，介紹了海洋氧含量下降是一個與氣候變化有關的令人擔憂的趨勢。Ocean Warming Affects Food WebC.The Oxygen Levels of Marine LifeNot all ocean animals are bothered by the decreasing oxygen levels.D. natural territories.B.Salty water holds less gas in the increasingly warmer ocean.（3）What can be inferred from the passage? A.Global warming reduces the amount of oxygen in the air.C.The lack of attention to the warming of tropical oceans.（2）Which of the following is a reason for the oxygen loss in the ocean? A.The survival of predators and various marine animals.C. Aside from food web problems, animals face various other physiological challenges as their bodies adjust to lower oxygen levels. Chinese shrimp (蝦) move their tails less vigorously to preserve energy in lower oxygen environments. Some creatures, such as jellyfishes, are more tolerant of low oxygen than others are. But all animals will feel the impact of deoxygenation because they all have evolved their oxygen capacity for a reason, says Oschlies. Any drop in oxygen is going to damage survivability and performance, he says.（1）According to the first two paragraphs, what worries scientists the most? A. A warming ocean loses oxygen for two reasons: First, the warmer a liquid bees, the less gas it can hold. That is why carbonated drinks go flat faster when left in the sun. Second, as polar sea ice melts, it forms a layer of water above colder, more salty sea waters. This process creates a sort of lid that can keep currents from mixing surface water down to deeper depths. And because all oxygen enters the surface, less mixing means less of it at depth. Escaping predators (食肉動物), digestion and other animal activities—including those of humans—require oxygen. But that essential ingredient is no longer so easy for marine life to obtain, several new studies reveal. 【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，是一篇科普類閱讀，要求考生在捕捉細節(jié)信息的基礎上，進一步根據上下文的邏輯關系，進行分析，推理，概括和歸納，從而選出正確答案。文章第一段前四句話點明了文章中心：我們看到的黑板大多是綠色的，為什么叫黑板？通讀全文也可知文章主要講述了黑板發(fā)展過程中顏色從黑色變成綠色的過程和原因。故選D。 （3）考查細節(jié)理解?？芍ｉL讓學生把他們的迷你板拼湊在一起是為了創(chuàng)造一個大的空間來畫地圖。In 1800 when a Scottish headmaster named James Pillans wanted his students to draw maps, the students couldn39。 （2）考查推理判斷。根據第一段中的，...late 18thcentury students used their own mini boards made of slate (石板) or painted wood...可知，18世紀的學生用的是“迷你板”。回答了黑板為什么是綠色的？
