Here’s an idea whose time has come: A flu shot that doesn’t require an actual shot.

For the first time, researchers have tested a flu vaccine patch (疫苗贴) in a human clinical trial and found that it delivered as much protection as a traditional injection with a needle. Doctors and public health experts have high hopes that it will increase the number of people who get immunized (免疫的) against the flu.

Seasonal flu is responsible for up to half a million deaths around the world each year according to the World Health Organization. A team led by Georgia Tech engineer Mark Prausnitz has come up with an alternative method that uses “microneedles”. These tiny needles are so small that 100 of them, arranged in order on a patch, can fit under your thumb (拇指). Yet they’re big enough to hold vaccine for three types of flu.

None of the study volunteers had serious side effects. The groups that got patches had mild skin reactions that were not seen in the regular needle group, while the volunteers in the regular needle group were more likely to experience pain. Overall, 70 percent of the volunteers who got vaccine patches said they’d rather use them again than get a traditional flu shot. The study authors declared it a success on all fronts.

The biggest beneficiaries could be people in low-and-middle—income countries, where flu vaccines are hard to come by. Reducing pain is nice, but other benefits-the patch costs less, is easier to transport, doesn’t require refrigeration, can be self-administered and doesn’t cause waste of needles — are even better.

“Microneedle Patches have the potential to become ideal candidates for vaccination programs,” wrote Katja Hoschler and Maria Zambon of Public Health England.

Did you get a flu shot this year？For the first time，the Centers for Disease Control and Prevention in the US is recommending that all children aged from 6 months to 18 years receive the flu vaccine.

Vaccines battle diseases caused by bacteria and viruses.A weakened form of the germ (病菌) is introduced into the body.The body makes special substances called antibodies (抗体) to fight the germs.If the actual germs were to attack，the antibodies would fight.Because there are many kinds of flu viruses，scientists must create a new vaccine formula (处方) each year.Researchers must make a prediction.

It is like forecasting the weather.Sometimes they are right on，and sometimes they are off.But even when the vaccine does not closely match circulating flu types，it can make the illness less serious.

“The flu vaccine is not as effective as the polio (小儿麻痹症) vaccine or the measles vaccine，” says Dr.William Schaffner of Vanderbilt University School of Medicine.“It’s not a great vaccine，but it is in fact quite a good vaccine.”

But a flu vaccine doesn’t work for everyone.There are certain people who should be careful about taking it，because the vaccine is produced in eggs.Those who are allergic (过敏的) to eggs should not take it.If you have a fever，you should wait until you recover.

Some people are afraid that they might get the flu from the flu shot.Scientists say that it is not possible，because the viruses in the flu shot are inactivated.But some minor side effects such as low­grade fever and body ache could occur.If they do，they begin soon after the shot and usually last only one to two days.

Did you know？Smallpox was the first disease people tried to prevent by putting a virus into a healthy person.In 1796，English scientist Edward Jenner placed some infected material under a boy’s skin.

B．antibody to fight the germs

D．germ to be injected into the body

A．is as effective as the polio and the measles vaccines

B．is worse，compared with the polio and the measles vaccines

C．does help to make illness less serious

D．is quite good because it works for everyone

3.We can infer from the passage that________.

A．those who are not allergic to eggs can take the flu vaccine

B．not all the flu vaccines are effective for everyone

C．you should go to a doctor if you have a fever after taking the flu vaccine

D．it is possible that some people might get　 the flu from the flu shot

A long time ago, there lived a poor man whose real name has been forgotten. He was little and old and his face was wrinkled, and that was why his friends called him Mr. Vinegar. His wife was also little and old, and they lived in a little old cottage at the back of a little old field.

"John," said Mrs. Vinegar, "you must go to town and buy a cow. I will milk her and churn（搅拌） butter and we shall never want for anything."

"That is a good plan," said Mr. Vinegar, so he started off to town while his wife waited by the roadside.

Mr. Vinegar walked up and down the street of the town looking for a cow. After a time, a farmer came that way, leading one that was very pretty and fat.

"Oh, if I only had that cow," said Mr. Vinegar, "I would be the happiest man in the world!"

"She's a very good cow," said the farmer.

"Well," said Mr. Vinegar, "I'll give you these 50 gold pieces for her."

The farmer smiled and held out his hand for the money, "You may have her," he said, "I always like to oblige（施恩惠） , my friends!"

Mr. Vinegar took hold of the cow's halter and led her up and down the street. "I am the luckiest man in the world," he said, "for only see how all the people are looking at me and my cow!"

But at one end of the street, he met a man playing bagpipes（风笛） . He stopped and listened -- Tweedle Dee Tweedle Dee.

"Oh, that is the sweetest music I ever heard," he said, "and just see how all the children crowd around the man and give him pennies! If I only had those bagpipes, I would be the happiest man in the world!!"

"I'll sell them to you," said the piper.

"Will you? Well then, since I have no money, I will give you this cow for them."

"You may have them," answered the piper, "I always like to oblige a friend."

Mr. Vinegar took the bagpipes and the piper led the cow away.

"Now we will have some music," said Mr. Vinegar, but try as hard as he might, he could not play a tune. He could get nothing out of the bagpipes but "squeak, squeak". The children instead of giving him pennies laughed at him.

The day was chilly and in trying to play the pipes, his fingers grew very cold. He wished he had kept the cow.

He just started for home when he met a man who had warm gloves on his hands. "Oh, if I only had those pretty gloves," he said, "I would be the happiest man in the world."

"How much will you give for them?" asked the man.

"Oh, I have no money, but I will give you these bagpipes," answered Mr. Vinegar.

"Well," said the man, "you may have them for I always like to oblige a friend."

Mr. Vinegar gave him the bagpipes and drew the gloves on over his half frozen fingers. "How lucky I am," he said as he trudged（跋涉） homeward. His hands were soon quite warm, but the road was rough and the walking hard. He was very tired when he came to the foot of the steep hill. "How shall I ever get to the top?" he said. Just then he met a man who was walking the other way. He had a stick in his hand which he used as a cane to help him along.

"My friend," said Mr. Vinegar, "if only I had that stick of yours to help me up this hill, I would be the happiest man in the world!"

"How much will you give me for it?" asked the man.

"Well, I have no money, but I will give you this pair of warm gloves," said Mr. Vinegar.

"Well," said the man, "you may have it for I always like to oblige a friend."

Mr. Vinegar's hands were now quite warm, so he gave the gloves to the man and took the stout（结实的） stick to help him along. "How lucky I am!'' he said as he toiled upward.

At the top of the hill he stopped to rest. But as he was thinking of all his good luck that day, he heard someone calling his name. He looked up and saw only a green parrot sitting in a tree.

"Mr. Vinegar, Mr. Vinegar," it cried.

"What now?" said Mr. Vinegar.

"You're a dunce（傻瓜） , you're a dunce!'' answered the bird, "you went to seek your fortune and you found it, then you gave it for a cow, and the cow for some bagpipes, and the bagpipes for some gloves, and the gloves for a stick which you might of cut by the roadside. He He He, you're a dunce! You're a dunce!''

This made Mr. Vinegar very angry. He threw the stick at the bird with all his might. But the bird only answered, "You're a dunce! You're a dunce!" And the stick lodged in the tree where he could not get it again.

Mr. Vinegar went on slowly for he had many things to think about. His wife was standing by the roadside and as soon as she saw him, she cried out, "Where's the cow? Where's the cow?" "Well, I just don't know where the cow is," said Mr. Vinegar. And then he told her the whole story.

1.What’s the meaning of the underlined word in the passage?

2.How many exchanges happen in the passage?

3.Why does the parrot think Mr.Vinegar foolish?

4.What’s Mrs.Vinegar’s feeling after she knew the fact?

The idea that history is an outdated course of study that will lead to limited career options has spread. 1. It is a wonderful way to prepare for a successful future. Here are a few reasons why it’s important that today’s students continue to learn about the past.

Understanding where people come from is key in understanding who we are. 2. It’s deeply influenced the world and its citizens. For this reason, it’s important to understand history in order to understand why people are the way that they are.

3. Through history classes, you can experience a change in the way you think. You’ll look at things from a new angle, as you understand the world in a new way. In the end, this change can improve your ability to assess and understand situations, make educated decisions, and learn how to weigh the consequences linked with each choice before you.

Learning from the past prevents future mistakes. 4. From wars to fashion to political trends, historians are often able to make predictions about the future based upon the past. By having a firm grasp on what happened in the past, today’s generation can better prepare for a brighter future by making the right decisions — instead of repeating old mistakes.

5. The idea that a degree in history can’t lead to a good career is untrue. In fact, students who graduate with degrees in history can become lawyers, business owners, foundation leaders, and non-profit leaders. Besides, history degrees can lead to working as an educator, a leader in a historical organization, a writer, an editor, a journalist, or a producer of multimedia materials.
