What do you get when you mix six little pigs, four monkeys and the deadly Ebola virus? Bad news, according to a recent experiment by Canadian researchers.
The experiment is the first to suggest that the Ebola virus can spread through the air. The study, published in November, detailed how the virus apparently moved from pigs to monkeys without their coming into physical contact. Previously, researchers thought animals had to touch to pass along the virus, which has been blamed for the deaths of more than 1,500 people.
In the experiment, researchers infected six piglets with Ebola. The team then placed the infected piglets in a room with several monkeys. A barrier separated the monkeys from the pigs, so the two species could not touch. And yet, after about a week, two monkeys became sick, infected with the virus. A few days later, the other two monkeys also fell sick with Ebola.
The Ebola virus is named for a river in the Democratic Republic of the Congo in Africa, close to where the germ was discovered. The virus causes high fevers and deadly bleeding disorders in primates, including people and monkeys. It is often deadly. However, scientists previously believed that the virus spread only through direct contact with the blood or other body fluids of an infected person or animal. Other viruses, including the ones that cause chicken pox and the common cold, are known to spread through the air.
Though Ebola too appeared to spread through the air in the laboratory experiment, researchers haven’t documented any cases of airborne infection under normal conditions. Since the discovery of Ebola in 1976, it has infected more than 2,200 people. Of that total, only 13 people fell ill apparently without coming into direct contact with an infected animal or person. If Ebola spreads easily through the air, scientists and doctors would expect to see more such cases.
1.What does the underlined part “Bad news” in Paragraph1 refer to?
A. The animals will only spread the virus to other animals.
B. Canadian researchers have not reached a conclusion.
C. The virus will be spread among people by pigs and monkeys.
D. The pigs and monkeys will get infected with the virus.

A. The Ebola virus can be deadly to animals in the wild.
B. The Ebola virus can spread without direct physical contact.
C. The Ebola virus can kill humans after they get infected with it.
D. Animals have to touch each other to pass along the Ebola virus.

b. It spreads totally differently from chicken pox.
c. It cannot spread through other body fluids besides blood.
d. People usually suffer from high fevers after getting infected.
e. It spread only through direct contact with the blood in the past.
A. abe B. ad C. abc D. bcde
4.It is implied about the Ebola virus in the last paragraph that ___.
A. it has killed thirteen people in total through air spreading
B. it cannot cause any human infections under normal conditions
C. spreading through the air is not an efficient route of transmission
D. more than 2,200 people have died because of the infection of the virus

3.
Highly organized people make sure they find time every week or more to organize their things. Stuff does not stay organized on its own; it needs to be reorganized continuously and consistently. Use small bits of time to clean out a drawer or put old clothes into a box for donation.

You have removed the things you don’t need. Will you replace them when you see something on sale? Instead of bargain shopping without planning ahead, write down exactly what you need and buy only those items. 4. Items on sale will only produce more waste.
Work hard
Put in a little effort. 5. Staying organized is not all a breeze. It requires that you work hard with recognition that when you work harder, you can enjoy your mess-free home life later. What’s more important is to remember what you work for is meaningful to you.
