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.The underlined word “vaccine” (in Para.1) refers to________.
| A．virus used for fighting against disease |

| 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 |
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 |
When people take the flu vaccine，________.
| A．they’ll be allergic to eggs |
| B．their bodies will ache for 5 days |
| C．they probably have a low fever |
| D．they won’t catch a flu ever after |
Lying in the sun on a rock, the cougar （美洲狮）saw Jeb and his son, Tom, before they saw it．Jeb put his bag down quickly and pulled his jacket open with both hands, making himself look big to the cougar．It worked．The cougar hesitated, ready to attack Jeb, but ready to forget the whole thing, too．
Jeb let go of his jacket, grasped Tom and held him across his body, making a cross．Now the cougar’s enemy looked even bigger, and it rose up, ready to move away, but unfortunately Tom got scared and struggled free of Jeb．
“Tom, no!” shouted his father．
But Tom broke and ran and that’s the last thing you do with a cougar．The second Tom broke free, Jeb threw himself on the cougar, just as it jumped from the rock．They hit each other in mid-air and both fell．The cougar was on Jeb in a flash, forgetting about Tom, which was what Jeb wanted．
Cougars are not as big as most people think and a determined man stands a chance, even with just his fists．As the cougar’s claws（爪子）got into his left shoulder, Jeb swung his fist at its eyes and hit, hard．The animal howled（吼叫）and put its head back．Jeb followed up with his other fist．Then out of the comer of his eye, Jeb saw Tom．The boy was running back to help his father．
“Knife, Tom,” shouted Jeb．
The boy ran to his father’s bag, while Jeb started shouting as well as hitting, to keep the cougar’s attention away from Tom．Tom got the knife and ran over to Jeb．The cougar was moving its head in and out, trying to find a way through the wall Jeb was making out of his arms．Tom swung with the knife, into the cougar’s back．It howled horribly and ran off into the mountains．
The whole fight had taken about thirty seconds．
16．Why did Jeb pull his jacket open when he saw the cougar?
A．To get ready to fight． B．To frighten it away．
C．To protect the boy． D．To cool down．
17．What do we know about cougars?
A．They are afraid of noises． B．They hesitate before they hit．
C．They are bigger than we think． D．They like to attack running people．
18．How did Jeb try to hold the cougar’s attention?
A．By keeping shouting and hitting． B．By making a wall out of his arms．
C．By throwing himself on the cougar． D．By swinging his fists at the cougar’s eyes．
19．Which of the following happened first?

Our “Mommy and Me” time began two years ago．My next-door neighbor and fellow mother, Christie, and I were out in our front yards, watching seven children of age 6 and under ride their bikes up and down．“I wish I could take one of my children out alone,” said Christie．
Then we worked out a plan: When Christie takes one of her children out, I’ll watch her other three．And when she watches two of mine, I’ll take someone out．
The children were extremely quick to accept the idea of “Mommy and Me” time．Christie’s daughter, McKenzie, went first．When she returned, the other children showered her with tons of questions．McKenzie was smiling broadly．Christie looked refreshed and happy．“She’s like a different child when there’s no one else around,” Christie shared with me quickly．With her mother all to herself, McKenzie didn’t have to make an effort to gain attention．
Just as Christie had noticed changes in McKenzie, I also discovered something different in each of my children during our alone times．For example, I am always surprised when my daughter, who is seldom close to me, holds my hand frequently．My stuttering（口吃的）son, Tom, doesn’t stutter once during our activities since he doesn’t have to struggle for a chance to speak．And the other son, Sam, who’s always a follower when around other children shines as a leader during our times together．
The “Mommy and Me” time allows us to be simply alone and away with each child —talking, sharing, and laughing, which has been the biggest gain．Every child deserves（应得到）to be an only child at least once in a while．
20．What is the text mainly about?
A．The experience of the only child being with mother．
B．The advantage of spending time with one child at a time．
C．The happy life of two families．

22．What is one of the changes the author finds in her children?
A．The daughter acts like a leader． B．Sam holds her hand more often．
C．The boys become better followers． D．Tom has less difficulty in speaking．
23．The author seems to believe that ___________．
A．having brothers and sisters is fun
B．it’s tiring to look after three children
C．every child needs parents’ full attention
D．parents should watch others’ children
It was a winter morning, just a couple of weeks before Christmas 2005．While most people were warming up their cars, Trevor, my husband, had to get up early to ride his bike four kilometers away from home to work．On arrival, he parked his bike outside the back door as he usually does．After putting in 10 hours of labor, he returned to find his bike gone．
The bike, a black Kona 18 speed, was our only transport．Trevor used it to get to work, putting in 60-hour weeks to support his young family．And the bike was also used to get groceries（食品杂货），saving us from having to walk long distances from where we live．
I was so sad that someone would steal our bike that I wrote to the newspaper and told them our story．Shortly after that, several people in our area offered to help．One wonderful stranger even bought a bike, then called my husband to pick it up．Once again my husband had a way to get to and from his job．It really is an honor that a complete stranger would go out of their way for someone they have never met before．
People say that a smile can be passed from one person to another, but acts of kindness from strangers are even more so．This experience has had a spreading effect in our lives because it strengthened our faith in humanity（人性）as a whole．And it has influenced（影响）us to be more mindful of ways we, too, can share with others．No matter how big or how small, an act of kindness shows that someone cares．And the results can be everlasting．
16．Why was the bike so important to the couple?
A．The man’s job was bike racing． B．It was their only possession．
C．It was a nice Kona 18 speed． D．They used it for work and daily life．
17．We can infer from the text that ____________．
A．the couple worked 60 hours a week． B．people were busy before Christmas
C．the stranger brought over the bike D．life was hard for the young family．
18．How did people get to know the couple’s problem?
A．From radio broadcasts． B．From a newspaper．
C．From TV news． D．From a stranger．
19．What do the couple learn from their experience?
A．Strangers are usually of little help． B．One should take care of their bike．
C．News reports make people famous． D．An act of kindness can mean a lot．
