Tamiflu does not kill but prevents H1N1 from further proliferation (繁衍) till the virus limits itself in about 1-2 weeks (its natural cycle).H1N1, like other Influenza A viruses, only infects the upper respiratory tract and proliferates (only) there.The only way of entry are the nostrils(鼻孔) and mouth/ throat.In a global epidemic of this nature, it's almost impossible not coming into contact with H1N1.
Contact with H1N1 is not so much of a problem as proliferation is.
While you are still healthy and not showing any symptoms of H1N1 infection, in order to prevent proliferation, some very simple steps can be practiced:
1.Frequent hand-washing.
2."Hands-off-the-face" approach.Resist all temptations to touch any part of face (unless you want to eat or bathe).
3.Gargle(漱口) twice a day with warm salt water (use Listerine if you don't trust salt).H1N1 takes 2-3 days after initial infection in the throat/ nasal cavity to proliferate and show characteristic symptoms.Simple gargling prevents proliferation.In a way, gargling with salt water has the same effect on a healthy individual that Tamiflu has on an infected one.Don't underestimate this simple, inexpensive and powerful preventative method.
4.Similar to 3 above, clean your nostrilsat least once every day with warm salt water,Which is very effective in bringing down viral population.
5.Strengthen your natural immunity with foods that are rich in Vitamin C .If you have to supplement with Vitamin C tablets, make sure that it also has Zinc to boost absorption.
6.Drink as much of warm liquids as you can.Drinking warm liquids has the same effect as gargling, but in the reverse direction.They wash off proliferating viruses from the throat into the stomach where they cannot survive, proliferate or do any harm.
7.All these are simple ways to prevent, within means of most households, and certainly much less painful than to wait in long queues outside public hospitals.

A Charlotte, NC, lawyer bought a box of very rare and expensive cigars, and then insured them against fire among other things.Having smoked his entire great cigars within a month, the lawyer filed claim (索赔) against the insurance company.
In his claim, the lawyer stated the cigars were lost "in a series of small fires".Of course the insurance company refused to pay, giving the obvious reason that the man had consumed the cigars in the normal way.
The lawyer brought the case to the court and out of everybody’s expectation, he actually won! At the end of the trial the judge agreed with the insurance company that the claim was crazy.But the judge said that the lawyer held a policy (保险单) from the company in which it had promised that the cigars were insured and that it would insure them against fire.Because the company didn’t say what is considered to be unacceptable fire, it had to pay the claim.
Rather than put up with long and costly appeal process, the insurance company accepted the punishment and paid $ 15 ,000 to the lawyer for his loss of the rare cigars lost in the "fires."
After the lawyer cashed the check, the insurance company had him arrested and accused him of arson (纵火罪).With his own insurance claim from the previous case being used against him, the lawyer was charged with burning his insured possessions on purpose and was sentenced to 24 months in prison and a $ 24,000 fine.The lawyer had smoked all the cigars ___.

Fruit also makes up a flowering plant. It carries the seeds . The purpose of fruit is to protect a plant’s seeds and help them get spread about. Wind and water spread seeds .So do animals when they eat fruit and drop the seeds .
There are two main types of fruit: fleshy and dry. Fleshy fruits are soft and juicy , the way we usually think of fruits . Peaches ,plums ,and apples are all fleshy fruits . Dry fruits are thin and hard . Grains like wheat and rice , or nuts are dry fruits.
You’ve eaten seedless oranges and grapes . How can they be fruits? It’s because people have changed the way they grow fruit. They can now grow seedless fruit . Seedless fruit comes from special plants called hybrids(杂交生物体) . A hybrid is made by combining two varieties of a fruit to form a new variety . This hybrid grows and produces seeds . But the plants grown from these seeds are seedless . These plants cannot reproduce themselves.
A tomato is a vegetable , right? No , it’s actually a fruit . Other food we think of as vegetables—such as squash , peppers ,and eggplant—also are fruit . They’re fruit because they carry seeds and develop from flowers . Here’s another surprise . Scientists classify the tomato as a berry(浆果) . In addition , they don’t consider some fruits we call berries to be true berries because a berry is normally a type of fruit with a lot of seeds inside it . Technically ,
a strawberry , isn’t a berry , because it has its seeds on the outside . The red part is just the tip of the strawberry stem that’s enlarged.
Fruits are a source of nourishing(滋养) substances that keep us alive and healthy . For example , they contain many vitamins , especially vitamins A and C, and many minerals . They also provide fibre for a healthy digestive system and carbohydrates that the body needs to make energy.

With the theme "Cherishing the earth's resources, transforming the mode of development and living a low-carbon lifestyle," China's Ministry of Land and Resources held a ceremony this Thursday to mark the 41st World Earth Day, aims to generate new ideas of resource-saving, especially among the younger generation. In fact, Chinese young urbanities are turning to the seemingly trendy low-carbon lifestyle.
But for the country as a whole to achieve a low-carbon economy, it could mean ordinary people paying more for electricity, water, gas or simply every purchase. Of necessity, a low-carbon economy would be the basis of China's economic growth, yet it comes with a high price tag. Everybody longs for fresh air, clean water and healthy surroundings. But, who is going to pay for that?
For those who are still working hard for the basic necessities of life, sharing the cost of a greener environment can be taxing. For those who are already victimized by environmental pollution, additional expenditure for saving the environment is hard to bear. Behind all the lofty goals and loaded phrases of climate change
negotiations, in everyday terms, the Chinese want to know whether companies will make them pay the cost of saving energy or whether government would come up with new levels.
They have reasons to worry. The recent hike in the charges of utilities, such as natural gas, water and electricity, have led to widespread public grievance(抱怨,牢骚), for the increases were imposed without proper public hearing. Besides the practice of monopoly State-owned enterprises raising prices at will does not seem to bode well for a low-carbon economy.
The government has a responsibility to strengthen regulation of utility charges and make the pricing mechanism more transparent. In the age of the low-carbon economy, the Chinese government needs to strike a new balance between public welfare and business competitiveness.
How far the initiatives toward a low-carbon economy succeed depends on whether they truly benefit ordinary people and is accepted by them. The majority cannot sacrifice their life to build a greener world for the few.The author probably agrees to call on ____________.
A.more and more citizens to devote themselves to the “Low-carbon economy” for the sake of our earth immediately |
B.the rich to generally pay for the bill, which aims at saving our planet. |
C.our government to take proper measures to make the “Low-carbon economy” benefit more people |
D.all the big enterprises to reduce their prices to build a greener world |
According to the passage, which of the following statements is NOT TRUE?
A.Some people can’t afford their everyday expenses, let alone pay for a better environment. |
B.Putting forward the “Low-carbon economy” costs much. |
C.The balance between public welfare and business competitiveness in China now is not that good for the “Low-carbon economy”. |
D.Now that it’s hard for us to make the “Low-carbon economy” into practice, our government should p![]() |

Motherhood may make women smarter and may help prevent dementia(痴呆) in old age by bathing the brain in protective hormones(荷尔蒙) , U.S. researchers reported on Thursday.
Tests on rats show that those who raise two or more litters of pups do considerably better in tests of memory and skills than rats who have no babies, and their brains show changes that suggest they may be protected against diseases such as Alzheimer’s(早老痴呆症). University of Richmond psychology professor Craig Kinsley believes his findings will translate into humans.
“Our research shows that the hormones of pregnancy(怀孕) are protecting the brain, including estrogen(雌激素), which we know has many neuroprotective (保护神经的) effects,” Kinsley said.
“It’s rat data but humans are mammals just like these animals are mammals,” he added in a telephone interview. “They go through pregnancy and hormonal changes.”
Kinsley said he hoped public health officials and researchers will look to see if having had children protects a woman from Alzheimer’s and other forms of age-related brain decline.
“When people think about pregnancy, they think about what happens to babies and the mother from the neck down,” said Kinsley, who presented his findings to the annual meeting of the Society of Neuroscience in Orlando, Florida.
“They do not realize that hormones are washing on the brain. If you look at female animals who have never gone through pregnancy, they act differently toward young. But if she goes through pregnancy, she will sacrifice her life for her infant—that is a great change in her behavior that showed in genetic alterations(改变) to the brain.”What does the phrase “litters of pups” mean in the second paragraph?
A.Baby rats. | B.Animals. | C.Old rats. | D.Grown-up rats. |
What can protect the brain of a woman according to the passage?
A.Estrogen. | B.The hormones of pregnancy. |
C.More exercise. | D.Taking care of children. |
“It’s rat data but humans are mammals just like these animals are mammals.” What does the sentence suggest?
A.The experiments on the rats have nothing to do with humans. |
B.The experiments on the rats are very important for animals. |
C.The experiments on the rats are much the same on humans. |
D.The experiments on the rats are much the same on other animals. |
Which title is the best for this passage?

I told my friend Graham that I often cycle two miles from my house to the town centre but unfortunately there is a big hill on the route.He replied, “You mean fortunately.”He explained that I should be glad of the extra exercise that the hill provided.
My attitude to the hill has now changed.I used to grumble as I approached it but now I tell myself the following.This hill will exercise my heart and lungs.It will help me to lose weight and get fit.It will mean that I live longer.This hill is my friend.Finally I comfort myself with the thought of all those silly people who pay money to go to a gym and sit on stationery exercise bicycles when I can get the same value for free.I have a smile of satisfaction as I reach the top of the hill.
Problems are there to be faced and overcome.We cannot achieve anything with an easy life.Helen Keller was the first deaf and blind person to gain a university degree.Her activism and writing proved inspirational.She wrote,“Character cannot be developed in ease and quiet.Only through experiences of trial and suffering can the soul be strengthened,vision cleared,ambition inspired and success achieved.”
One of the main determinants of success in life is our attitude towards adversity(逆境).From time to time we all face hardships,problems.accidents、afflictions and difficulties.Some are of our making but many confront us through no fault of our own.While we cannot choose the adversity we can choose our attitude towards it.
Douglas Bader was 21 when in 193l he had both legs cut off following a flying accident.He was determined to fly again and went on to become one of the leading flying aces in the Battle of Britain with 22 aerial victories over the Germans.He was an inspiration to others during the war.He said, “Don't listen to any-one who tells you that you can’t do this or that.That's nonsense.Make up your mind,you'll never use crutches(拐杖)or a stick,then have a go at everything.Go to school,join in all the games you can.Go anywhere you want to.But never,never let them persuade you that things are too difficult or impossible.”
The biographies(传记)of great people are full of examples of how they took steps to overcome the difficulties they faced.The common thread is that they did not become depressed.They chose their attitude.They chose to be positive.They took on the challenge.They won.
Nevertheless.there is still the problem of how you change your attitude towards adversity.Which of the following is true according to the author of the passage?
A.Climbing hills on bicycles is the best way to take exercise. |
B.People are silly to pay to go to the gym. |
