Studying volcanoes is a demanding profession. Hazel Rymer frequently has to struggle through rainforests, climb to the top of mountains, then climb 200 metres into the crater of active volcanoes. But the 38-year-old volcanologist does her best to make it sound less alarming than it is. “Driving to work is more risky,” she insists. “And the deepest I go into the crater of a volcano is about 300 metres,” she adds, trying to make it all sound as ordinary as taking the dog for a walk.
Hazel has been studying volcanoes for a long time, so it’s not surprising she is used to the danger. Her interest in volcanoes began at school. A teacher gave her a book about Pompeii. “I remember reading about the eruption of Vesuvius and the destruction of the city,” she explains. “The thought of all those people just frozen in time had quite an effect on me and I am still excited by their dangerous beauty today.”
Nowadays, volcanoes are getting more and more unpredictable. There have been many changes in sea level caused by global warming and melting ice caps. These have resulted in some dormant volcanoes erupting, so studying them is more dangerous than ever before. Hazel says that although she doesn’t take any unnecessary risk she has had some frightening moments. Her worst experience was on the slopes of Mount Etna in Sicily, when she was slowly surrounded by lava. “I had a choice of walking ten hours to get around the lava flow or just walking across it,” she explains. She chose to pick a path across the cooler rocks in the lava stream. “I guess it was five metres. The flow was 1,000°C, so if you hesitated your boots would begin to melt. It was scary, but it really was a practical decision --- there wasn't time to do anything else.”
And what about the future? “I haven’t been to the volcanoes in Indonesia yet. And I would love to spend some time working in the Antarctic,” she says. “I would also like to know why quiet lava flows erupt from some volcanoes and why other volcanoes go bang.” In other words, Hazel Rymer won’t be exchanging her volcanoes for the relative safety of driving to work just yet. Hazel’s claim that “driving to work is more risky” than exploring volcanoes shows that ______.
| A．people have exaggerated the dangers of volcanoes in the past |
| B．Hazel does not really understand the dangerous situations she puts herself in. |
| C．there are many bad drivers in the place where Hazel lives |
| D．Hazel is being modest and understating the dangers she faces |
When did Hazel first become interested in volcanoes?
| A．When she was visiting Italy. |
| B．When she was at school. |
| C．When she was twenty. |
| D．When she saw Vesuvius. |
The underlined word “these” (in paragraph 3) refers to __________.
| A．melting ice-caps | B．volcanic eruptions |
| C．changes in sea level | D．higher temperatures |
When Hazel was on Mount Etna she had to ________.
| A．take a dangerous route |
| B．take an unnecessary risk |
| C．leave her boots behind |
| D．walk for ten hours around the mountain |
In the future, Hazel wants to ________.
| A．revisit volcanoes she knows |
| B．go on holiday to the Antarctic |
| C．find a less dangerous job |
| D．discover new things about volcanoes |
As I was busy working on my work plan in my bedroom, I could hear my four children playing upstairs. Suddenly, I heard the children running down the stairs and shouting, “Freddie, Freddie.” I heard the word “window” and rushed outside, heart in mouth. My three-year old son Freddie was lying on his side on the ground. I cried for my husband Simon to dial 999 and within minutes the air ambulance arrived. They quickly took him in the helicopter. During the flight, Freddie was looking at me and I remember thinking was a good sign, but then his eyes began to roll. As the doctors tried to stabilize(稳定) him, I couldn’t believe what was happening.
When we arrived at the hospital in Portsmouth, there were some doctors and nurses waiting for us and they immediately set to work on Freddie. I was hopelessly wishing everything would be alright, but Freddie had broken his skull in two places and blood clots were forming in his brain. He needed surgery(外科手术), and only a surgeon at another hospital in Bristol could do it. This meant another helicopter ride, but we couldn’t go with Freddie because there was no enough space. Simon and I drove the long 130 miles from our home in north Devon in silence. Neither of us dared say what we were thinking, “What if we get there and he’s dead?” “Is he going to be brain-damaged?”
Freddie was just coming out of surgery when we arrived. The surgeon said it had gone well. When I finally saw him, I hardly recognize my child—he was covered in tubes and there were wires coming out of his head.
On the third day, Simon went home to see our three girls and to pick up some clean clothes for us. While he was gone, the pressure in Freddie’s brain suddenly increased. He was taken into theater again and this time I fell apart. Luckily, the surgery managed to stabilize Freddie. After almost a week, Freddie was finally woken up. When he opened his eyes, he looked at me. He didn’t say anything, but I knew straight away that it was my old Freddie, and that he was going to be alright. Over the next two weeks, his recovery went well. After help with learning to swallow again and encouragement with speaking, he was soon playing with his Gruffalo cards and eating meals by himself.
I still don’t know how the accident happened, but we got some idea from our girls. Clearly Freddie and Minnie had been sitting on the window ledge, and Freddie must have opened it to look out and fallen 20 feet onto the ground below.
The guilt I feel is awful— for weeks I was full of “ if onlys”, and we put window locks everywhere. Six months later, although the accident seems a lifetime ago, it has changed me. I feel differently about life now. I’ve left my job to put my children first. I want to spend every minute with them.The underlined sentence in paragraph 1 shows the author was ______________.

A study shows that nearly ninety percent of teens report that they have tried alcohol. That’s an increase of 23 percent in just four years!
Each year, 1.1 billion cans of beer are drunk by students aged 15-19 years old. Beer is the most common alcoholic drink among teens—81 percent of the drinkers had tried it. Beer is followed by wine with 63 percent, hard liquor(烈酒) with 53 percent and wine coolers with 35 percent.
When the young people are asked why they drank, the most common answer is that drinking is “something to do”. If a teen’s parents drink alcohol, the teenager is more likely to start drinking at an early age. Also, tens see all of their friends drinking alcohol so they think it is the must-to-do thing. Peer pressure is probably the hardest thing teens have to deal with. What’s more, teens often drink alcohol because it makes them feel older and cooler.
Researchers asked 56,000 students about their drinking habits and grades, to see how drinking might affect their grades in school. The results seem to be clear. Students who got a C level or lower tend to use three times as much alcohol as those who got B’s or A’s.
Alcohol use can be deadly. About 8,100 young people are killed per year in alcohol-related accidents. Eight young people die per day as a result of a drunk-driving accident. Between 50 and 65 percent of all teen suicides (自杀) occur after the young people drink.
So you see, drinking the alcohol doesn’t always end up with a good time. The next time you try to push someone to drink or someone tries to push you to drink, please remember this. One drink can set the habit for life. Why not throw it away?The reasons for teens’ drinking alcohol are mentioned EXCEPT that _______________.
| A．they think it is cool to drink alcohol |
| B．their parents set a bad example to them |
| C．alcohol can make them happier |
| D．peer pressure plays an important role |
What can we learn from paragraph 4?
| A．Drinking alcohol makes students stupid. |
| B．Good students never try alcohol. |
| C．Drinking habits have something to do with IQ. |
| D．Students with poor grades tend to use more alcohol. |
The passage was written mainly to ______________________.
| A．show the bad effect of drinking alcohol |
| B．show how many teenagers drink alcohol |
| C．tell teenagers not to try alcohol |
| D．tell the reasons why teenagers drink alcohol. |
Growing up, I wanted to be just like my mom. She was kind. People always seemed to feel comfortable in her presence. For years, she was a volunteer in our community. I loved going to the local nursing home with her where she taught a ceramic class.
On one summer day, Mama told me to get changed and meet her at the car.
I had planned to spend the day at the lake with friends. Why did she have to ruin everything? I imagined the cool lake water. Irritated, I climbed into the car and slammed the door shut. We sat in silence. I was too upset to make conversation.
“Tasha, would you like to know where we are going?” Mama asked calmly.
“No,” I said.
“We are going to volunteer at a children’s shelter today. I have been there before and I think it would benefit you,” she explained.
When we reached the shelter, Mama rang the doorbell. Moments later, we were greeted by a woman. She led us to the front room where all of the children were playing. I noticed a baby whose body was scarred with iron marks. I was told it was because she wouldn’t stop crying. The majority of the children had noticeable physical scars. Others hid their emotional wounds.
As I took in my surroundings, I felt a gentle tug on my shirt. I looked down to see a little girl looking up at me. “Hi. You want to play dolls with me?” she asked. I looked over at Mama for reinforcement. She smiled and nodded. I turned back and said, “Sure.” Her tiny hand reached up and held mine, as if to comfort me.
My mom taught me a valuable lesson that summer. I returned to the shelter with her several times. During those visits, some of the children shared their troubled pasts with me and I learned to be grateful for what I had. Today as I strive to instill (逐渐灌输) these values in my own child, I reflect back to that experience. It was a time that I will never forget. The author admired her mom for ________.
