【題目】Directions:Complete the following passage by using the words in the box. Each word can only be used once. Note that there is one word more than you need.
Cure isn’t a word normally used in the 【1】 of AIDS. For most of the 35 years since HIV, the virus responsible for the disease, was first identified, doctors have viewed the notion of a cure as more 【2】 than fact.
That’s because HIV is a virus unlike any other. It disables the very immune cells that are 【3】 to destroy it, carrying out the ultimate deadly ambush(埋伏)whenever the guard of immune 【4】 comes down, months or sometimes even years later.
Yet for the first time in the HIV epidemic that 【5】 affects nearly 37 million people worldwide, some experts are starting to aim for a cure cautiously. The National Institutes of Health(NIH)is funding HIV cure efforts and advocacy groups like amfAR are also 【6】 resources into not just treating HIV, but also finding ways to eliminate it completely.
“Absolutely HIV can be cured,”says Rowena Johnston, vice president and director of research for amfAR.“The question is how.”
Doctors today have no trouble keeping HIV under control in people who are infected, thanks to antiretroviral(ARV)drugs, which stop the virus from replicating(復(fù)制). If it is not making more copies of itself. HIV cannot spread to infect new cells. That can 【7】 into healthier, longer lives for people who are HIV-positive.
Powerful as the current drug treatments are, they can’t actually 【8】 the body of infected cells. For self-preservation, some HIV lies latent(潛伏性的)inside certain immune cells. These are the viruses that come coaring back when people stop taking their medications.
But the latest report this month revealed the strongest evidence that these latent viruses can be activated and eliminated, at least in animals. Dr. Dan Barouch and his colleagues showed that a drug that stimulates the immune system, 【9】 with a powerful antibody, prevented HIV from roaring back in five of 11 animals, six months after they stopped taking ARVs.“I think our data raises the 【10】 that an intervention achieving a functional cure is possible,”says Barouch.

【1】考查名詞。句意:“治愈”這個(gè)詞在艾滋病的語境中并不常用。分析句子結(jié)構(gòu)可知,空處填名詞,再根據(jù)句意可知,context是名詞,意為“文本、語境”,與題意相符,故選H。
【2】考查形容詞。句意:自從艾滋病病毒首次被發(fā)現(xiàn)以來的35年里,醫(yī)生們認(rèn)為治愈艾滋病的想法更多的是幻想而不是事實(shí)。分析句子結(jié)構(gòu)可知,空處填形容詞,根據(jù)句意可知,more…than…意為“不是……而是”,fantasy在此處做形容詞,意為“虛幻的”,故選G。
【3】考查固定搭配。句意:它會(huì)破壞原本要摧毀它的免疫細(xì)胞,在幾個(gè)月甚至幾年之后,當(dāng)免疫防御系統(tǒng)崩潰時(shí),它就會(huì)進(jìn)行終極的致命伏擊。分析句子結(jié)構(gòu)可知,空處填動(dòng)詞,根據(jù)句意可知,be supposed to是固定搭配,意為“本該、應(yīng)該”,與題意相符,故選C。
【4】考查名詞。句意:它會(huì)破壞原本要摧毀它的免疫細(xì)胞,在幾個(gè)月甚至幾年之后,當(dāng)免疫防御系統(tǒng)崩潰時(shí),它就會(huì)進(jìn)行終極的致命伏擊。分析句子結(jié)構(gòu)可知,空處填名詞,根據(jù)句意可知,immune defense意為“免疫防御”,與題意相符,故選J。
【5】考查副詞。句意:然而,在目前影響全球近3700萬人的艾滋病流行中,一些專家首次開始謹(jǐn)慎地尋找治療方法。分析句子結(jié)構(gòu)可知,空處填副詞,currently是副詞,意為“目前”,與題意相符,故選K。
【6】考查動(dòng)詞。句意:美國(guó)國(guó)立衛(wèi)生研究院(NIH)正在資助艾滋病病毒的治療工作,像amfAR這樣的倡導(dǎo)組織也在投入大量資源,不僅用于治療艾滋病,而且還在尋找徹底消滅艾滋病的方法。分析句子結(jié)構(gòu)可知,空處填動(dòng)詞,且此處用現(xiàn)在進(jìn)行時(shí),再根據(jù)句意可知,pour是動(dòng)詞,在此處意為“傾注、投入”,與題意相符,故選I。
【7】考查動(dòng)詞。句意:艾滋病毒不能傳播感染新細(xì)胞。這可以轉(zhuǎn)化為艾滋病毒陽性患者更健康、更長(zhǎng)壽的生活。分析句子結(jié)構(gòu)可知,空處填動(dòng)詞原型,translate into意為“轉(zhuǎn)化為”,與題意相符,故選A。
【8】考查動(dòng)詞。句意:盡管目前的藥物治療很有效,但它們實(shí)際上無法清除體內(nèi)的感染細(xì)胞。分析句子結(jié)構(gòu)可知,空處填動(dòng)詞原型,rid意為“使擺脫”,與題意相符,故選B。
【9】考查過去分詞。句意:丹·巴魯奇博士和他的同事們展示了一種刺激免疫系統(tǒng)的藥物,結(jié)合一種強(qiáng)大的抗體,在11只動(dòng)物停止服用抗逆轉(zhuǎn)錄病毒藥物6個(gè)月后,阻止了其中5只動(dòng)物的艾滋病毒卷土重來。分析句子結(jié)構(gòu)可知,空處和其后短語做a drug的后置定語,再結(jié)合句意可知,be combined with意為“與……相結(jié)合”,所以此處略去be動(dòng)詞,用過去分詞combined做后置定語,故選D。
【10】考查名詞。句意:我認(rèn)為我們的數(shù)據(jù)提出了一種剝離方法,即干預(yù)實(shí)現(xiàn)功能性治療是可能的。分析句子結(jié)構(gòu)可知,空處填名詞,根據(jù)句意可知,deprive在此處用作名詞,意為“剝奪、剝離”,與題意相符,故選E。

【題目】 You have probably heard that Japan has among the highest life expectancy(預(yù)期壽命) in the world and that the island of Okinawa(沖繩) has the greatest concentration(濃度) of centenarians(百歲老人). But do you know that two-thirds of the centenarians are still functioning independently? That means they are in their own homes, cooking their own meals and living their lives fully - at about 100 years old!
The elders there are less likely than their counterparts in the United States to have heart disease, dementia(癡呆) or certain cancers. Their bones are stronger than those of similarly aged people around the world. Many of these residents are the subjects of one of the largest studies of centenarians ever conducted. Since 1976, nearly a thousand centenarians on the islands have been studied.
More than anything, the Okinawa diet has long captured the headlines. Before knowing what the Okinawans eat, there is a valuable lesson in how they eat.
Remember this term: hara hachi bu. It is translated into English as “Stop eating when you are 80% full.” With hara hachi bu, the philosophy is that you should still be a little hungry when you push the plate away. You are also advised to reduce your portion(食物的分量) sizes, use smaller plates and eat more slowly.
There is a basic biological (生物學(xué)的) reason this works. It takes about 20 minutes for the stomach to send signals to the brain that it is full. Unfortunately, most people can shovel down another several hundred calories in that short time. Instead, if you push the plate away and just wait, you will have eaten less and still feel satisfied.
Eating less is associated with longevity, but of course, that also depends on what you eat. Okinawans typically eat seven different fruits and vegetables and 18 different foods a day, and more than 200 different foods and spices regularly in their overall diet.
However, the younger generations are eating more meat and fast food instead of fish and soy. The elderly there are still widely revered(崇敬), but there are fewer of them, and they are less often living to 100 than in decades past.
【1】What is the key to the high life expectancy in Okinawa?
A.What they eatB.How they eat
C.Where they liveD.When they exercise
【2】Which of the following has the closest meaning to the underlined part “shovel down” in Paragraph 5?
A.fill inB.put down
C.fill outD.push away
【3】Which of the following statements about Okinawa is true?
A.The elderly are in bad need of mutual respect.
B.There are an increasing number of the elderly.
C.The younger generations have a varied diet.
D.Things are starting to change for the worse.
【4】Which could be the best title for the passage?
A.Eat less to live longer.
B.Healthy diets build longevity.
C.The Okinawa: a place of longevity.
D.Improve life expectancy? Slow down.
