Food sometimes gets poisoned with harmful things. A person who eats such food can get an illness called food poisoning. Food poisoning is usually not serious, but some types are deadly. The symptoms of food poisoning usually begin within hours of eating the poisoned food. Fever is one of the most common symptoms.
Certain microorganisms(微生物)cause most types of food poisoning. Bacteria and other microorganisms can poison eggs, meat, vegetables, and many other foods. After entering the body, these tiny living things release(释放)poisons that make people sick.
Some chemicals can also cause food poisoning. They are often added to food while it is being grown, processed, or prepared. For example, many farmers spray chemicals on crops to kill weeds and insects. Some people may have a bad reaction to those chemicals when they eat the crops.
Some plants and animals contain natural poisons that are harmful to people. These include certain kinds of seafood, grains, nuts, seeds, beans, and mushrooms.
When people handle food properly, the risk of food poisoning is very small. Microorganisms multiply rapidly in dirty places and in warm temperatures. This means that people should never touch food with dirty hands or put food on unwashed surfaces. Food should be kept in a refrigerator to stop microorganisms from growing. Meat needs to be cooked thoroughly to kill any dangerous microorganisms. People should also wash food covered with chemicals before eating it. Finally, people should not eat wild mushrooms or other foods that grow in the wild. Some of these foods may contain natural materials that are poisonous to humans. In addition, some types of fish can be poisonous.
Most people recover from food poisoning after a few days of resting and drinking extra water. If people eat natural poisons, they must go to the hospital right away to have their stomachs emptied.
1. Which of the following statements is NOT true?
A. Food when poisoned can make people sick.

C.can be noticed within hours
D.can he ignored
3.Food poisoning can be caused by all the following EXCEPT__________

In William Shakespeare’s play, Julius Caesar, there is major difference between two of the characters, Brutus and Mark Antony, Brutus was very honorable and Antony was very persuasive. When Brutus spoke at Caesar’s funeral, he appealed to the people’s logic and Antony spoke to the emotions of the people. Antony was very smart and used his brain frequently during the play and Brutus was very naive(天真的,率直的) about many of things.
Brutus was very honorable in the way that he always told people the truth. Antony was persuasive in the way that he used people to get whatever he wanted. For example, Antony used Lepidus to seek revenge on all of the conspirators (同谋者,阴谋者) to take the blame for their deaths. Brutus’ speech at Caesar’s funeral was very short and to the point and spoke to the logic of the people in the crowd. For example, Brutus spoke in a detached way about Caesar’s death while Antony spoke to the emotions of the crowd by crying and talking about all the good things that Caesar did for Rome. Antony’s intelligence was very apparent throughout the play and Brutus appeared to be naive about many things. Antony as smart in the way that he controlled people to his own advantage. Brutus appeared to be naive throughout the whole play because he believed everyone was as honorable as he. Brutus did not question what he was told, assuming it was always true.
In conclusion, in William Shakespeare’s play, Julius Caesar, there is a major difference between the two characters, Brutus and Mark Antony. The strongest contrast between the two characters appears to be their ability and inability to be both honorable and persuasive.

Thirteen, for me, was a challenging year. My parents divorced and I moved to a new town with my father, far from my old family and friends. I was terribly lonely and would cry myself to sleep each night. To ease my sadness, my father purchased an old horse for me at a local auction.(拍卖) I named him Cowboy.
Cowboy was without a doubt the ugliest horse in the world. But I didn’t care. I loved him beyond all reason. I joined a riding club and suffered rude comments and mean snickers about Cowboy’s looks. I never let on about how I felt, but deep inside, my heart was broken. The other members rode beautiful, registered horses.
When Cowboy and I entered the events where the horse is judged on appearance, we were quickly shown the gate. No amount of preparation and love would turn Cowboy into a beauty. My only chance to compete would be in the speed events. I chose the jumping race.?
One girl named Becky rode a big brown horse in the race events. She always won the blue ribbons.  Needless to say, she didn’t feel threatened when I competed against her at the next show. She didn’t need to. I came in next to last.
The stinging memory of Becky’s smirks(得意的笑) made me determined to beat her. For the whole next month I woke up early every day and rode Cowboy five miles to the arena (赛马场). We practiced running and jumping for hours in the hot sun and then I would walk Cowboy home totally exhausted. All of our hard work didn’t make me feel confident by the time the show came. I sat at the gate and sweated it out while I watched Becky and her horse charge through the course and finish in first place.
My turn finally came. I put on my hat, rubbed Cowboy’s neck and entered the arena. At the signal, we dashed toward the first fence, jumped it without trouble and raced on to the next one. Cowboy then flew over the second, third and fourth fences like a bird and I turned him toward the finish line. As we crossed the line the crowd was shocked into silence. Cowboy and I had beaten Becky and her fancy horse by two seconds!
I gained much more than a blue ribbon that day. At thirteen, I realized that no matter what the odds, I’d always come out a winner if I wanted something badly enough to work for it.
1. The underlined expression "shown the gate" (paragraph 3) most probably means ______.
A. told how to enter the arena
B. shown how to make the horse beautiful
C. removed from the competition early
D. told to enter the timed-speed events
2. When the final race finished, nobody cheered because________.
A. the audience didn’t like Cowboy      B. people envied the writer
C. the win was unexpected?        D. the writer bad run out of time
3. Why was the writer not confident of victory?
A. He was an inexperienced rider.
B. He had not practiced enough.
C. He believed he was unpopular with the crowd.
D. He thought his horse wasn’t as good as the others.
4. What did the writer learn from his experience?
A. Life can sometimes be unfair.
B. Anything is possible if one tries hard enough.
C. A positive attitude will bring success.
D. One should not make judgments based on appearance.

B
It was evening when my parents and I ventured across Nemeiben Lake, in Northern Saskatchewan. This vast lake had a unique reputation as being the best fishing and tourist resort.
With the boat undocked and the gear and luggage stored beneath the security of the seats, we set off into the setting sun at 8:30.
Unlike my parents , I had never been on a fishing boat before and was captivated(迷住) by the speed and grace in which it traveled through the waves. The lake was deserted as the sky began to darken and looked more threatening by the minute.
Suddenly the boat hit something with such a force that we all fell over in our seats. The whole boat shook for a moment, before water started to trickle slowly over stern. My father went to the back and after many attempts to start the engine, he began to look very worried. The water was now rushing in at a much faster rate, tipping the boat at an awkward angle.
We tried our best to hold on to something. The worst was yet to come. With our life jackets secured and fastened, we waited as the boat sank deeper into the water. We were soon immersed in the chilly depths. The biting cold was more terrifying than anyone could imagine.
My parents, who were dressed in floater jackets, clung desperately to each other, trying to keep their heads above water. I, on the other hand, wasn’t so fortunate. A strong gust of wind blew briskly across the lake, bringing with it, torrential rain and threatening thunderstorms. The strong waves carried me on into the night. The waves continued to pound violently, forcing me underwater.
The following morning a fisherman found us. By that time, our body temperatures were twenty-four degrees, which meant we were nearly dead. Later investigation showed that we had been in the water for fifteen hours.
60. What is the main idea of the passage?
A. An exciting experience my parents and I had
B. A disappointing experience my parents and I had
C. An adventurous experience my parents and I had
D. A strong experience my parents and I had
61. Unlike the other lakes in Northern Saskatchewan, the Nemeiben Lake____________.
A. was the most dangerous and threatening lake
B. was most famous for fishing and tourism
C. was the largest and deepest in this area
D. had a good reputation for its wildlife
62. What is the reason which caused the accident?
A. Because of the thunderstorms
B. Because the boat sank.
C. Because the boat hit something with force.
D. Because we had no life jackets

If you want to deal with the association (交往) between boys and girls properly, here are some advice for you to follow.
1) Keep a normal and healthy state of mind. Our schools and classes are made up of boys and girls. It is very natural for the boys and girls to contact each other and build up the friendship with the students of the other sex. Generally speaking, we should broaden the circle of the association. We should make as many friends as possible. We should have more friends of the opposite sex instead of one or two. We should contact the students in public instead of in secret. 
2) Contact students of opposite sex warmly, generously and sincerely. Don’t be too nervous or too shy in contact with a person of the opposite sex. In that case it is very difficult for you to make a lot of friends, as no one likes a person who is too shy to say a word. If you are too shy a person, you can also find a way out. First of all, you can contact the students with the same interest and hobby with you. As both of you have much in common, you may have much to talk about. If you keep doing like that, little by little, you will gladly find you are also as free to express yourself as others.
3) Don't fall into the ditch (泥潭) of early love. The boys and girls at adolescence(青春期)are rich in feelings and full of imagination. They are easy to regard the friendship as a sign of love, and fall in love with other at an early age. In my opinion, boys and girls at middle school are too young and too tender to shoulder the heavy duty of love. Early love is a green apple that can't be eaten. An apple won't taste sweet until it is fully ripe. Do keep out of early love.
1  The underlined word “broaden” in the passage means ________.
A. close down         B. make small        C. make broad         D. make known
2. We should contact (交往)the student of the opposite sex in the following ways EXCEPT ________.
A. with a good state of mind            B. in public
C. in secret                          D. warmly and generously
4. A person at adolescence is NOT ________.
A. rich in feelings                    B. full of imagination   
C. old enough to fall in love            D. easy to regard the friendship as a sign of love
4. The best title of the passage is ________.
A. The early love
B. Some advice on how to associate between boys and girls
C. The contact does good not only to the boys but also to the girls
D. How to talk with a girl

Your mobile phone rings and instead of the usual electronic signals it’s playing your favourite music.A friend sends your favourite song to cheer you up.One day,a record company might forward new records and music videos to your phone.
The mobile business is getting into the music business.For the moment,the interest is in pleasant ring tones,but some companies are hoping to take full advantage of the next generation of mobile phones—all purpose gadgets that blend phone,personal stereo,video player and Internet browser into one.
Finally,record companies might send new records and videos to fans who register their cell phone numbers.
The fans could pass music or songs along to friends—a kind of musical trading card.Unlike Internet tracks,mobile downloads would be easy for record companies to control,said former record industry official Ralph,Simon,who is now chairman of Yourmobile,based in Santa Monic,California.
“If you pass a song along to other phones through a network,each phone can be charged,” said Simon.“It’s like going through toll gate (收费站).There’s more possibility for copyright control than there is on the Internet.”
Massachusetts-based Converse is offering service in Portugal and the Netherlands that lets people record tunes on their voice mail or send music as presents to friends.Finally,people might be able to sing karaoke and pass them along.The company is sure that people will want to use music to reach out and touch someone.
“A mobile phone is not a listening machine,and you’ll be disappointed if you think you can change it into a radio,” said Ouzel,a creative manager for Converse in Israel.“But if someone sends you a song while you’re on vacation,you appreciate the feeling.”
72.The underlined word “blend” in the second paragraph most probably means _____.
A.send                B.come               C.mix                 D.compare
73.“Massachusetts-based Converse”in the sixth paragraph probably refers to ______.
A.a person                                      B.a city in Israel        
C.a state of the USA                    D.a company
74.Record companies ______ the idea of passing songs and music along mobile phones.
A.are worried about                         B.are interested in
C.try hard to stop                             D.take no notice of
75.According to Ralph Simon it would be easier to _______ through mobile phone network than through the Internet.
A.protect copyright of music works   B.send personal messages
C.pass along songs and music            D.send voice mail
