On a sunny day last August, Tim heard some shouting. Looking out to the sea carefully, he saw a couple of kids in a rowboat were being pulled out to sea.
Two 12-year-old boys, Christian and Jack, rowed out a boat to search for a football. Once they'd rowed beyond the calm waters, a beach umbrella tied to the boat caught the wind and pulled the boat into open water. The pair panicked and tried to row back to shore. But they were no match for it and the boat was out of control.
Tim knew it would soon be swallowed by the waves.
"Everything went quiet in my head," Tim recalls(回忆). "I was trying to figure out how to swim to the boys in a straight line."
Tim took off his clothes and jumped into the water. Every 500 yards or so, he raised his head to judge his progress. "At one point, I considered turning back," he says. "I wondered if I was putting my life at risk." After 30 minutes of struggling, he was close enough to yell to the boys, "Take down the umbrella!"
Christian made much effort to take down the umbrella. Then Tim was able to catch up and climb aboard the boat. He took over rowing, but the waves were almost too strong for him.
"Let's aim for the pier(码头)," Jack said. Tim turned the boat toward it. Soon afterward, waves crashed over the boat, and it began to sink. "Can you guys swim?" he cried. "A little bit," the boys said.
Once the were in the water, Tim decided it would he safer and faster for him to pull the boys toward the pier. Christian and Jack were wearing life jackets and floated on their backs. Tim swan toward land as water washed over the boys' faces.
“Are we almost there?" they asked again and again. "Yes," Tim told them each time.
After 30minutes, they reached the pier.
Why did the two boys go to the sea?

What does "it"in Paragraph 2 refer to?

Why did Tim raise his head regularly?

How did the two boys finally reach the pier?

LONDON - A British judge on Thursday sentenced a businessman who sold fake(假冒的) bomb detectors(探测器) to 10 years in prison, saying the man hadn't cared about potentially deadly consequences.
It is believed that James McCormick got about $77.8 million from the sales of his detectors - which were based on a kind of golf ball finder - to countries including Iraq, Belgium and Saudi Arabia.
McCormick, 57, was convicted(判罪) of cheats last month and sentenced Thursday at the Old Bailey court in London.
"Your cheating conduct in selling a great amount of useless equipment simply for huge profit promoted a false sense of security and in all probability materially contributed to causing death and injury to innocent people," Judge Richard Hone told McCormick. "you have neither regret, nor shame, nor any sense of guilt."
The detectors, sold for up to $42,000 each, were said to be able to find such dangerous objects as bombs under water and from the air. But in fact they "lacked any grounding in science" and were of no use.
McCormick had told the court that he sold his detectors to the police in Kenya, the prison service in Hong Kong, the army in Egypt and the border control in Thailand.
"I never had any had results from customers," he said.
Why was McCormick sentenced to prison?

According to the judge, what McCormick had done _______.

Which of the following is true of the detectors?

It can be inferred from the passage that McCormick _______.

Home to me means a sense of familiarity and nostalgia(怀旧). It's fun to come home. It looks the same. It smells the same. You'll realize what's changed is you. Home is where we ran remember pain, live, and some other experiences; We parted here; My parents met here; I won three championships here.
If I close my eyes, I can still have a clear picture in mind of my first home. I walk in the door and see a brown sofa surrounding a low glass-top wooden table. To the right of the living room is my first bedroom. It's empty, but it's where my earliest memories are.
There is the dining room table where I celebrated birthdays, and where I cried on Halloween-when I didn't want to wear the skirt my mother made for me. I always liked standing on that table because it made me feel tall and strong. If I sit at this table, I can see my favorite room in the house, my parents' room. It is simple: a brown wooden dresser lines the right side of the wall next to a television and a couple of photos of my grandparents on each side. Their bed is my safe zone. I can jump on it anytime - waking up my parents if I am scared or if I have an important announcement that cannot wait until the morning.
I'm lucky because I know my first home still exists. It exists in my mind and heart, on a physical property(住宅) on West 64th street on the western edge of Los Angeles. It is proof I lived, I grew and I learned.
Sometimes when I feel lost, I lie down and shut my eyes, and I go home. I know it's where I'll find my family, my dogs, and my belongings. I purposely leave the window open at night because I know I'll be blamed by Mom. But I don't mind, because I want to hear her say my name, which reminds me I'm home.
Why does the author call her parents' bed her "safe zone"(Paragraph 3)?

What can be learned from the passage?

Sometimes when she feels lost, the author will _______.

What is the author's purpose of writing this passage?

Fear may be felt in the heart as well as in the head, according to a study that has found a link between the cycles of a beating heart and the chance of someone feeling fear.
Tests on healthy volunteers found that they were more likely to feel a sense of fear at the moment when their hearts are contracting(收缩) and pumping blood around their bodies, compared with the point when the heartbeat is relaxed. Scientists say the results suggest that the heart is able to influence how the brain responds to a fearful event, depending on which point it is at in its regular cycle of contraction and relaxation.
Sarah Garfinkel at the Brighton andSussexMedicalSchoolsaid: "Our study shows for the first time that the way in which we deal with fear is different depending on when we see fearful pictures in relation to our heart."
The study tested 20 healthy volunteers on their reactions to fear as they were shown pictures of fearful faces. Dr Garfinkel said, "The study showed that fearful faces are better noticed when the heart is pumping than when it is relaxed. Thus our hearts can also affect what we see and what we don't see - and guide whether we see fear."
To further understand this relationship, the scientists also used a brain scanner(扫描仪) to show how the brain influences the way the heart changes a person's feeling of fear.
"We have found an importantmechanismby which the heart and brain‘speak’to each other to change our feelings and reduce fear," Dr Garfinkel said.
"We hope that by increasing our understanding about how fear is dealt with and ways that it could be reduced, we may be able to develop more successful treatments for anxiety disorders, and also for those for those who may be suffering from serious stress disorder."
What is the finding of the study?

The study was carried out by analyzing _______.

Which of the following is closest in meaning to "mechanism" in Paragraph 6?

This study may contribute to _______.
