For the last couple of weeks, I had been stuck in front of my computer working on a project that was very important to me. My every waking hour was consumed by the project and although I imagined that I would feel happy after completing parts of the project, I was confused to find that instead, I was feeling rather depressed. I tried a range of methods to help cheer myself up. I had a relaxing bath, cooked a delicious meal to enjoy with my family and even watched a lighthearted movie, but to no avail. It was only when I turned to think for a solution that the answer came to me: turn to nature!
The very next day, I grabbed my camera and a bottle of water and set off to spend a few hours walking in a nature reserve, even though it was pouring with rain. Within a couple of minutes I felt alive again. To be honest, I felt like a young school girl again and had to stop myself from hopping along the path singing, "I'm singing in the rain", a song I used to sing when I was a child. I think as adults we often try too hard to control our inner children and as a result we limit our own spirits, which only leads to depression and stress.
Interestingly, it has been shown that people who spend 40 minutes walking in a nature reserve have a drop in their blood pressure levels, but this does not happen when they spend a similar amount of time walking in a busy city center.
If you feel a little low in spirit and know that you have spent too much time indoors, relax completely, remove your shoes and let your inner child come out and play.The reason why the author felt depressed is that_______.
| A．she was afraid she couldn’t finish her work on time |
| B．she spent too much time indoors in front of her computer |
| C．her every waking hour was consumed by the project |
| D．the project was very important to her |
In the author's opinion, _______.
| A．adults should express their inner feelings freely |
| B．depression is usually caused by hard work |
| C．walking in a busy city center harms people's health |
| D．a bath can make people relaxed |
The last paragraph mainly serves as a(n) _______.
| A．explanation | B．warning |
| C．introduction | D．reminder |
Tail Spin
Two dolphins race around in a big pool in the Ocean Park. The smaller dolphin, Grace, shows off a few of her tricks, turning around and waving hello to the crowd. The most amazing thing about her, however, is that she's even swimming at all. She doesn't have a tail.
Grace lost her tail as a baby when she got caught up in a fish trap. When the dolphin arrived at the Ocean Park in December 2005, she was fighting for her life. “ Is she going to make it？” Her trainer, Abbey Stone, feared the worst. Grace did make it—but her tail didn't. She ended up losing her flukes and the lower part of her peduncle.
Over the past six years, she has learned to swim without her tail. Dolphins swim by moving their flukes and peduncle up and down. Grace taught herself to move another way—like a fish! She pushes herself forward through the water by moving her peduncle from side to side.
The movements put harmful pressure on Grace's backbone. So a company offered to create a manmade tail for her. The tail had to be strong enough to stay on Grace as she swam but soft enough that it wouldn't hurt her.
The first time Grace wore the artificial tail, she soon shook it off and let it sink to the bottom of the pool. Now, she is still learning to use the tail. Some days she wears it for an hour at a time, others not at all. “The new tail isn't necessary for her to feel comfortable，” says Stone, “but it helps to keep that range of motion (动作) and build muscles (肌肉)．”
Now, the dolphin is about to get an even happier ending. This month, Grace will star in Dolphin Tale, a film that focuses on her rescue and recovery. Her progress has inspired more than just a new movie. Many people travel from near and far to meet her. Seeing Grace swim with her manmade tail gives people so much courage.When Grace first arrived at the Ocean Park, her trainer worried about her ________.
| A．physical build |
| B．potential ability |
| C．chance of survival |
| D．adaptation to the surroundings |
A manmade tail is created for Grace to ________.

The story of Grace inspires people to ________.
| A．stick to their dreams |
| B．treat animals friendly |
| C．treasure what they have |
| D．face difficulties bravely |
We can make all the jokes we want about taking baths ourselves, but if we are ill in bed and can't get up, we'll be thankful to the nurses who help us get clean. While I am not a nurse, and have never given anyone a bath, I would imagine that it would take a lot of sympathy (同情) and patience to do so.
Yet those who attended the International Conference on Intelligent Robots and Systems last month were introduced to Cody, a robot that can bathe human beings.
The robot has a base that can be turned to all directions, two humanlike arms, and movable wrists (腕). It uses a camera to locate parts of the human body. It then uses bath gloves to clean with a little pressure.
The robot was designed at the Georgia Institute of Technology. Charles Kemp of the Healthcare Robotics Lab is the senior researcher for the project. In a test run, Cody was able to remove 96% of a test subject's dirt—not bad for a robot.
But don't go asking for Cody yet—he's still a model. Yet researchers believe that one day Cody may take the place of nurses for this task. Researchers say that Cody will give patients dignity and protect their personal information. I suppose that would depend on the patient. I'm not sure whether a robot using a camera would make me feel very dignified.
Even so, I can appreciate the need. We don't have enough nurses to go around, and those places that are the most shorthanded, for example, nursing homes, are those that have the most patients who are unable to bathe themselves. Still, before I get there, I hope they think of a better way to solve the problem.The writer thinks bathing others must ________.
| A．be a lot of fun |

| A．Why and where Cody was designed. |
| B．What Cody looks like and who designed it. |

We know from the fourth and fifth paragraphs that ________.
| A．Cody can bathe patients better than a real nurse can |
| B．robots like Cody are being produced in large numbers right now |
| C．Cody can take the place of nurses completely in hospitals |
| D．researchers think Cody can protect patients' personal information |
There is a need for Cody because ________.
| A．people are becoming lazier |
| B．it can bring down the cost of nursing |
| C．there are not enough nurses |

Every school has an ugly girl. In my primary school, it was me.
From first grade through fourth, I had to wear heavy orthopedic(整形外科的)shoes because of my weak ankles. I sounded like overweight elephant wearing bricks whenever I took a single step.
“Hey, Bigfoot！”
“Geez, you're going to start an earthquake！”
Then in sixth grade I had to start wearing glasses. Mom asked for the least expensive ones and that made me look like a fool.
“Four eyes！”
“Couldn't you cover up more of your faces? Why stop at the eyes？”
In Seventh, I started competing on the city swim team, thinking that if I got a killer body, nobody would notice my face. Wrong again. I loved being fast and winning ribbons now and then, but now I had red, wet eyes from the chlorine(氯) in the pool. I also did not develop a killer body.
I changed my strategy at Eighth grade, the last year of middle school. I offered my help to anyone who needs. I worked for other girls, so they could hang out with their friends. My new program began to work. People who would never have acknowledged my existence before were suddenly seeking me out.
I'd been feeling pretty good until one day I went to Christine's house to help her fill envelopes. Going into each envelope was invitation to Christine's birthday party; it was a big event at a fancy hotel. Complete with dinner. She asked me to help her address these envelopes. There was no envelope for me.
My heart was broken. I tried to escape from all the eyes. High school had to be better, right? Yes and no. Now that I'm here, I know there are still lots of shallow people judging you on what you're wearing or how cool your hair is, but there are also kids who talk to you because they liked your answers or just as you're kind, honest, and a good friend.
I still do kind things because I like the feeling I get when I am helping people. I, with my friends, went to children's hospital, playing games and reading to the sick kids.
I still had wet red and not a smart look, but you cannot tell me I am not beautiful. Every time I visit hospital, fiveyearold Terry grasps my hand, “Morri, you are so nice. I want to grow up to be just like you.”Why was Morri laughed at by her classmates when she was in primary school?
| A．She had weak ankles and eyesight. |
| B．Her glasses couldn't cover up her face. |
| C．She couldn't get along well with them. |
| D．She looked like an overweight elephant. |
Which of the following is the real reason for Morri competing on the city swim team?
| A．To win more ribbons. |
| B．To shift others' attention from her face. |
| C．To develop a killer body. |
| D．To have red wet eyes. |
From what Morri experienced in the last year of middle school, we can learn that ________.
| A．her classmates thought highly of her |
| B．she was popular among her classmates |
| C．she was often cheated by her classmates |
| D．her classmates just took advantage of her |
The passage is intended to encourage people to ________.

| B．take more sport activities including swimming |
| C．take others' comments into careful consideration |
| D．take positive attitude towards disadvantages in life |
As we know, the earth's climate has changed over time.The present rate of climate change depends, in large part, on human activities.Today, people all over the world are making everyday choices that help the environment.Small actions matter.In other words, climate change is your business.
A woman in Nicaragua buys fluorescent (荧光的) light bulbs that are 80 percent more energysaving than traditional ones. Many governments are now subsidizing energysaving lights to encourage people to turn to them.Consumers are discovering that the newgeneration bulbs help them save money in the long run.
Agriculture accounts for about 14 percent of global greenhouse gas emissions (排放) , and transporting the food around adds to the environmental cost.There is a team of young vegetable growers in the United Kingdom who want to encourage kids to start planting their own fruit and vegetables.
A young lawyer wearing business clothes rides her bicycle to work in a large U．S.city.She's been biking to work every day for the past two years and says it's a lot easier than many people think.A recent study shows that more Americans bike or walk to work today than before.
A university student from southeastern China carries a reusable shopping bag to cut back on disposable (一次性的) plastics.Some large shopkeepers have removed paper and plastic bags, and consumers are responding.
In Canberra, Australia, summers are hot and winters cold.To save electricity, Adam Wilson in Canberra uses an energysaving heating system, and he keeps the temperature lower than he did in years past.He still makes it through the summer without air conditioning.The passage mainly tells us that________.
| A．climate change is concerned with everyone |
| B．the global warming is getting worse |
| C．saving energy is of great necessity |

Around 200 million years ago, the earth was 18 degrees warmer than it is now. That might be a bit hot for humans, but it was just right for the giant dinosaurs that wandered about the earth during the Mesozoic (中生代的) era. A new study found that planteating dinosaurs may have contributed to the warming of the earthby releasing significant amounts of methane (甲烷)．
The study, published in science journal Current Biology, focused on sauropods, longnecked herbivores (食草动物) that munched (用力咀嚼) on the top of trees. They were the largest of the dinosaurs; food broke down in their stomachs for long periods of time. The researchers estimate that a sauropoda released 2,675 liters of methane per day—adding up to a large amount of the greenhouse gas being pumped from dinosaur's gut into the atmosphere.
Plant eaters naturally release methane as part of their digestive process. The larger the animal, the more methane it produces. Methane, a greenhouse gas, traps heat and remains in the atmosphere for approximately 915 years, which warms the atmosphere.
Today, some animals, such as cattle, goats and sheep, produce large amounts of methane as a byproduct to their food digestion. Methane is also released from human—influenced sources such as landfill, agricultural activities, coal mining and other industrial practices—which all contribute to today's climate change, according to the Environmental Protection Agency.
The researchers estimate that earth's sauropods would have produced about 520 million tons of methane per year—similar to the total amount of methane produced today by natural and manmade sources. However, the researchers warn that their numbers are estimates based on multiple assumptions about the digestive systems and populations of dinosaurs.
The author of the study David Wilkinson says the emission of methane from dinosaurs would have been just one of the causes of warm climate during the Mesozoic era. Other causes include gases produced from volcanoes, swamps, shallow seas and so on. Still, Wilkinson says，“ The amount of methane from dinosaurs is large enough to have a measurable effect.”Scientists think dinosaurs may have led to the global warming because ________.
| A．they ate everything they found |
| B．they usually had a good appetite |
| C．they released a lot of methane |
| D．there were too many dinosaurs on earth |

| D．By using mind pictures. |
David Wilkinson seems to believe that ________.
| A．methane had little effects on the earth |
| B．many other factors contributed to warm climate |
| C．other causes for warm climate were worth considering |
| D．dinosaurs were mainly to blame for global warming |
