When we hear of dangerous diseases, cancer and heart disease are often what first come
to mind. Recently, a virus called Ebola has reappeared in Guinea, killing 62 people so far. It leads to high fever, bleeding and so on. Ebola can kill 90% of those infected (感染), especially in underdeveloped societies like those in Africa.
Ebola is named after the Ebola River, where it was first discovered in 1976. There are five different types of the Ebola virus, each named after where they first happened: Sudan, Ivory Coast, Reston, Bundibugyo, and Zaire. The deadliest of the five, Zaire, was responsible for the 2012 outbreak, and is believed to be attacking Guinea.
Ebola is naturally found in fruit bats, which pass on the virus to other animals by biting or sucking on their blood. Humans who are suffering from the Ebola infection might have touched the bodily fluids (体液) of the infected animals. Once infected, a human becomes a carrier of the deadly virus.
Since we live in an interconnected world, where the situation in one country can affect us all, the effects of Ebola are huge: damaging trade relations, affecting foreign visitors, and weakening entire countries. Already the Guinea virus is spreading fast with a few cases spotted in Conakry—the capital city of Guinea, far away from the origin of the virus. It is feared that the disease may have already reached neighboring Liberia and Sierra Leone, too.
Unfortunately, there are no disease-specific treatments for Ebola. Healthcare workers only supply the infected people with water to keep them in good condition. Since there have been many cases of nurses catching the disease from patients, they are forced to wear strict protective clothes, and in some cases, not even allowed to get close to the infected. The fact that there is no cure for the Ebola virus is what makes the outbreak a challenging one to control.
1.From the text we know that ________.
A. Ebola is naturally found in fruit

2.What is Paragraph 4 mainly about?

Eating red meat is linked to cancer and heart disease, but are the risks big enough to justify giving up juicy burgers and delicious steaks? Probably not, according to researchers who reviewed data from 12 clinical trials involving about 54,000 people. In a series of controversial papers, the researchers argue that the increased health risks tied to red meat are small and uncertain, and that cutting back likely wouldn't be worth it for people who enjoy meat.
Those conclusions go against established medical advice. They were swiftly attacked by a group of famous U.S. scientists who took the unusual step of trying to stop the papers from being published until their criticisms were addressed.
The new work does not say red or processed meats like hot dogs and bacon are healthy, or that people should eat more of them. The team’s reviews of past studies generally support the ties to cancer, heart disease and other bad health outcomes. But the authors say the evidence is weak, and that there’s not much certainty meat is really the cause, since other diet and lifestyle factors could be at play.
If the latest example of how divisive nutrition research has become, with its uncertainties leaving the door open for conflicting advice. Critics say findings often aren't backed by strong evidence. Defenders counter that nutrition studies can rarely be conclusive because of the difficulty of measuring the effects of any single food, but that methods have improved.
Based on their analyses, the researchers said people do not have to cut back for health reasons. But they noted that their own advice is weak, and acknowledged that they didn't consider factors such as animal welfare and the environment. Indeed, the case that meat production is bad for animal welfare and the environment is stronger than the case that it's bad for human health, according to an editorial that accompanies the report.
Not all of the report authors agreed with its conclusions. Three of the 14 researchers said they support reducing red and processed meats. A coauthor of one of the reviews is also among those who called for a publication delay.
Those who pushed to postpone publication also questioned why certain studies were included in the reviews while others were left out.
As for his own diet, Dr. Gordon Guyatt, a member of the international research team that conducted the reviews, said he no longer thinks red or processed meats have significant health risks. But he said he still avoids them out of habit, and for animal welfare and environmental reasons.
1.What is the author’s purpose in writing the passage?
A.To introduce a new relationship between health and eating red meat.
B.To urge more people to keep away from eating red meat regularly.
C.To present a new controversial view on impacts of eating red meat.
D.To criticize nutrition studies for lacking of conclusive evidence.
2.What is the author’s attitude towards the new research?
A.Doubtful. B.Positive.
C.Disapproving. D.Objective.
3.Guyatt’s avoiding red meats has the weakest connection with ________.
A.health risks B.diet habits
C.animal welfare D.environmental protection
4.What can we learn from the recent research?
A.Red meats don’t have significant health risks.
B.Reducing meat consumption will be worth it.
C.The report authors have reached a consensus.
D.Consuming red meat will do good to health.
