It was a beautiful day at the beach—blue sky, gentle wind, calm sea．I knew these things because a man sitting five feet from me was shouting them into his mobile phone, like a play-by-play announcer （實況解說員）.

“IT’S A BEAUTIFUL DAY,” he shouted．“THE SKY IS BLUE, AND THERE’S A GENTLE WIND, AND THE WATER IS CALM, AND…”

Behind me, a woman, her mobile phone pressed to her ear was walking back and forth.

“She DIDN’T,” she was saying．“No．She DIDN’T．She DID? Really? Are you SERIOUS? She did NOT．She DID? No she…”

And so on．This woman had two children, who were playing in the sea．I found myself watching them, because the woman surely was not．A huge squid could have caught and snatched the children, and this woman would not have noticed．Or, if she had noticed, she’d have said, “Listen．I have to go, because a huge squid just……No! She didn’t ! She DID? No! She……”

And next to me, the play-by-play man would have said: “…AND A HUGE SQUID JUST ATE TWO CHILDREN, AND I’M GETTING A LITTLE SUNBURNED, AND …”

It used to be that the major trouble at the beach was the fellow who brought a boom box （便攜式錄音機） and turned it up so loud that the bass notes caused seagulls to explode．But at least you knew where these fellows were; you never know which beachgoers have mobile phones．You’ll settle next to what appears to be a sleeping sunbather, or even （you hope） a corpse , and you’ll lie happily on your towel, and you’ll get all the way to the second sentence of your 467-page book before you fall asleep to the hypnotic surge of the surf （催人入夢的潮聲）, and …

BREEP! BREEP! The corpse sits up, feels urgently for its mobile phone, and shouts “Hello! I’m at the beach! Yes! It’s nice! Very peaceful! What? She did? No, she didn’t! She DID? No, she…”

Loud mobile-phoners never seem to get urgent calls．Just once, I’d like to hear one of them say, “Hello? Yes, this is Dr．Johnson．Oh, Dr．Smith．You’ve opened the abdominal cavity （腹腔）? Good! Now the appendix should be right under the … What? No, that’s the liver．Don’t take THAT out, ha ha! Oh, you did? My God! OK, now listen carefully…”

From the passage we can know that the writer of the passage _____.

       A．had a wonderful holiday at the beach

       B．must have suffered a lot because of the terrible weather

       C．is only interested in talks by doctors about operation

       D．experienced an unhappy holiday at the beach

       B．A huge squid ate two children while their mother was not watching.

       C．Some people used to play boom box while spending their holidays at the beach.

       D．Some people often make loud mobile phone calls without caring for others.

The underlined word“ corpse”in this passage has the closest meaning to________.

       A．a(chǎn) dead body           B．a(chǎn) loud mobile phone        

       C．a(chǎn) sound sleeper        D．a(chǎn) sleep lover

In the past the fellow who brought a boom box_________.

       A．turned it up to make the seagulls happy

       B．turned it up to cause the seagulls to explode

       C．might cause less trouble than the beachgoers with mobile phones

Once upon a time, there was an island inhabited by: Happiness, Sadness, Knowledge, and all the rest of it, including Love. One day it was announced to the feelings that the island would sink, so all constructed boats and left. Except for Love.

    Love was the only one who stayed. Love wanted to hold out until the last possible moment.

When the island had almost sunk, Love decided to ask for help.

    Richness was passing by Love in a grand boat. Love said, "Richness, can you take me with you?"

    Richness answered, "No, I can't. There is a lot of gold and silver in my boat. There is no place here for you."

    Love decided to ask Vanity(虛榮) who was also passing by in a beautiful vessel. "Vanity, please help me!"

    "I can't help you, Love. You are all wet and might damage my boat," Vanity answered.

    Sadness was close by so Love asked, "Sadness, let me go with you."

    "Oh . . . Love, I am so sad that I need to be by myself!"

    Happiness passed by Love, too, but she was so happy that she did not even hear when Love called her.

February has long been a month of romance. With the sweet smell of roses in the air, romantic films hit cinemas and love stories fill newspapers and magazines.

    On the 14th day, it is a custom for a boy to take his girlfriend out to dinner, buy her flowers and chocolates, write poems, sing to her or even spell out her name with rose petals! This is what you see on Valentine’s Day, a day named after Valentine who was a priest in the third century Rome. When the emperor (皇帝) decided that single men could become better soldiers than those with wives, he didn’t allow marriage.

    But Valentine continued to perform marriage ceremonies for young lovers in secret. When his actions were discovered, the emperor sentenced him to death. While in prison, it is said that Valentine fell in love with the daughter of his prison guard. Before his death, he wrote her a letter, which he signed “From your Valentine”, an expression that is still in use today. Valentine died for what he believed in and so he was made a Saint (圣徒), as well as becoming one of history’s most romantic characters.

     Nowadays, Valentine’s Day is also popular among Chinese young people. Some students are planning to make Valentine’s cards for parents, teachers and friends. Others want to hold parties at which they will exchange small gifts and eat heart-shaped cakes. The idea is to have fun and encourage people to share in the spirit of St. Valentine.

Why did the emperor in Rome not allow marriage in his country?

    A. Because there were few women in his country at that time.

    B. Because he thought men without wives could be better soldiers.

    C. Because there wasn’t enough food for so many people.

    D. Because he wanted to control the birth rate.

Valentine was put into prison because ______.

    A. he killed one of the soldiers           B. he stole a lot of food

    C. he didn’t obey the emperor’s order      D. he didn’t want to be a soldier

The last paragraph mainly tells us ______.

    A. students in China send cards to their teachers

    B. it is a good idea to celebrate Valentine’s Day in China

    C. it is interesting to celebrate Valentine’s Day in China

    D. Valentine’s Day is also popular in China now

The best title for this passage should be ______.

    A. Valentine’s Day   B. A Brave Priest   C. Valentine’s Day in China   D. A Romantic Man
