英語四級(jí)聽力真題及答案

埃博拉病毒是一種十分罕見的病毒,這種病毒并不是一種,而是屬于纖維病毒科扒正的數(shù)種病毒的總稱,這種病毒能夠在靈長類動(dòng)物中造成傳染,一旦感染上這種病毒,死亡率是非常高的,這種病毒具體是什么呢?下面為大家介紹埃博拉病毒的由來。

1、名稱由來

埃博拉病毒(Ebolavirus)也曾譯作伊波拉病毒,因?yàn)樵诜侵拊翣枺ìF(xiàn)剛果民主共和國)的埃博拉河最早發(fā)現(xiàn)它的存在,由此得名。最近西非埃博拉病毒疫情嚴(yán)重,引起了全世界的關(guān)注。埃博拉病毒并非一種新型病毒,早在1976年就已被發(fā)現(xiàn)。

2、發(fā)病癥狀

埃博拉病毒是纖維病毒科埃博拉病毒屬下面多種病毒的總稱,感染的主要癥狀為埃博拉病毒出血熱,患者會(huì)出現(xiàn)嘔吐、惡心、腹瀉、膚色產(chǎn)生變化,全身酸痛、體外出血、體內(nèi)出血、發(fā)燒等癥狀。

3、感染方式

埃博拉病毒是一種可以在人和牲畜之間傳染的病毒,潛伏期最長可達(dá)20天,病程較短,病毒侵蝕人體的能力十分強(qiáng),從染上病毒到病發(fā)死亡最短不過3~4天,傳染性極強(qiáng),與患者的嘔吐物、體液、血液、分泌物等有過接觸的人極易感染上該病毒,致死率超過90%。目前,生物醫(yī)學(xué)界認(rèn)為果蝠是埃博拉病毒的原宿主,但目前還沒有得到確切證實(shí)。

由來

據(jù)百科介紹,埃博拉病毒病是由纖絲病毒科(filoviridae)的埃博拉病毒(Ebola virus,EBOV)所引起的一種急性出血性傳染病。主要通過患者的血液和排泄物傳播,臨床主要表現(xiàn)為急性起病,發(fā)熱,肌痛,出血,皮疹和肝腎功能損害。 埃博拉本是剛果(金)(舊稱扎伊爾)北部的一條河流的名字。1976年,一種不知名的病毒光顧這里,瘋狂地虐殺埃博拉河沿岸55個(gè)村莊的百姓,致使數(shù)百生靈涂炭,“埃博拉病毒”因此得名。

癥狀

埃博拉病毒會(huì)導(dǎo)致多器官損害,主要影響肝、脾和腎。潛伏期3~18天,臨床主要表現(xiàn)為突起發(fā)病,有發(fā)熱、劇烈頭痛、肌肉關(guān)節(jié)酸痛,時(shí)而有腹痛,發(fā)病2~3天可出現(xiàn)惡心、嘔吐、腹痛,腹瀉黏液便或血便,腹瀉可持續(xù)數(shù)天。病程4~5天進(jìn)入極期,辯畢發(fā)熱持續(xù),出現(xiàn)意識(shí)變化,如乎液譫妄、嗜睡。

Ebola outbreak: 2nd person dies in Mali By Faith Karimi and Marilia Brocchetto, CNN

November 12, 2014 -- Updated 1206 GMT (2006 HKT)

Eight of nine Ebola patients who've been treated in the U.S. have survived the dangerous virus. That includes Dr.Craig Spencer. Officials say he's cured of the disease less than a month after he was diagnosed with it.

Dr. Spencer had contracted Ebola while treating victims in Guinea, but he didn't show symptoms until after he'd gotten back home to New York.

At this time, there are no other people in the U.S. with the hemorrhagic fever. That's not the case in Africa. In this year's outbreak, more than 13,000 Ebola cases have been reported, half of those who've gotten it in Africa have died.

In a region desperate for good news, some progress in the fight against the Ebola epidemic. At treatment centers in Liberia,there are more empty beds and fewer burials. A sign that the number of cases is down.

The surprising slowdown was confirmed by the World Health Organization. Health officials say they are cautiously optimistic, but warn against declaring a premature victory.

This are slowing down. But are we there yet? No. Do we need to do more? Yes.

Even more treatment centers are being built, as international aid continues to arrive in the region. We just entered the high risk area in Monrovia medical unit.

This one of the kind treatment center built by U.S. troops is set to open. U.S. health workers have been training extensively at the 25 bed facility to trade medical workers infected with the virus.

A different scene in neighboring Sierra Leone where the number of Ebola cases continues to climb. Treatment centers in Freetown are still crowded with the sick.

And outside the capital, aid workers are busy delivering food to rural villages that remain under quarantine.

And in Ghana, West African leaders were screened with the laser thermometer for signs of the virus as they gather to talk about how to fight the epidemic. They say despite some short term gains, economies in the hardest hit nations are still suffering, and much more international help is needed.

Some people think reading shall be chosen. Because some books are good to human beings and some books are harmful to people.

Some people think that men should read books widely. Because wide reading can help man get much knowledge. And man can use it to change the world.

It is my point that reading must be selectively. Because reading is important to man. Some books can help man but some books can lead some people to crime. It can be seen in the newspapers and watched on TV. We can make full use of some good books and gain more useful knowledge. It can make our life more beautiful. We must give up those unhelpful books. They are not good to us. Reading them is wasting time and money. So reading selectively is an important part in reading.

英語四級(jí)聽力真題原文及答案

埃博拉病毒其實(shí)在中國古代明末時(shí)期也發(fā)生過一次,現(xiàn)將原文摘錄如下:明末年間,京師大疫,有胸腹?jié)M生白毛者,有頭大如斗,眼鼻俱沒者,有兩腮紅腫,痰喘雍塞者,呼吸間死以萬計(jì),癥狀但多感覺全身散架似的,全身酸痛,寒熱往來,亦有上吐下泄者,實(shí)為痧癥也。

埃博拉病毒按中國古代醫(yī)學(xué)實(shí)際為痧疫流行而己,即時(shí)按刮痧療法治之可愈,配合刺血療法加中藥治療,治痧之法有很多種,暫列痧癥名稱如下:

風(fēng)痧,暑痧,陰痧,陽痧,紅痧,烏痧,吐痧,瀉痧,緊痧,慢痧,暈痧,絞腸痧,抽筋痧,喑痧,悶痧,落弓痧,噤口痧,撲盯辯蛾痧,角弓痧,瘟痧,滿痧,脫腸痧,羊毛痧,羊筋痧凱肢缺,紫皰沙,瘋痧,血末痧,蛔結(jié)痧,心煩嗜睡痧,遍身青筋痧,遍身腫饑罩脹痧,霍亂痧,瘧疾痧,頭痛痧,心痛痧,身重痧,半身不遂痧,臌脹痧,血衄痧,婦人倒經(jīng)痧,痰喘氣急痧等等,無一不要人命,只要治療即時(shí),一般好的很快。治法太多,這里不便不祥述。
