1 . A Portland, Oregon man has become the first person to travel across Antarctica by himself without receiving any assistance.

Colin O’Brady has completed the 1,500-kilometer trip. He crossed the continent in 54 days. Friends, family and other people followed his progress through messages and pictures he left on social media.

O’Brady spoke with his wife Jenna Besaw by telephone soon after he completed the journey. “It was an emotional call,” she said. “He seemed overwhelmed by love and appreciation, and he really wanted to say ‘thank you’ to all of us.”

The 33-year-old O’Brady documented the trip on the social networking services Instagram. He called his journey “The Impossible First”. He wrote that he traveled the last 129 kilometers in one big, final push to the finish line. The distance took over one day to complete. O’Brady wrote, “While the last 32 hours were some of the most challenging hours of my life, they have quite honestly been some of the best moments I have ever experienced.”

The day before, he wrote that he was “in the zone” and thought he could make it to the end without stopping. “I was listening to my body and taking care of the details to keep myself safe,” he wrote. “I called home and talked to my mom, sister and wife. I promised them I would stop when I need to.”

Other people have traveled across Antarctica, but they all had some form of assistance. They either had better, more plentiful supplies or devices that helped move them forward.

In 2016, British explorer Henry Worsley died in his attempt to travel alone across Antarctica unassisted. Worsley’s friend Louis Rudd, also from Britain, is attempting an unaided solo journey in Worsley’s honor. He was competing against O’Brady to be the first to do it. Besaw told the Associated Press that her husband plans to stay in Antarctica until Rudd finishes his trip.

1. What did O’Brady think of his journey in Antarctica?

A．It was pleasant.	B．It was discouraging.
C．It was impossible to complete.	D．It was hard to complete.

2. What did O’Brady promise his family?

A．Making sure of his safety.	B．Trying to achieve the goal.
C．Keeping in touch with them.	D．Stopping the travel halfway.

3. Why does O’Brady still remain in Antarctica?

A．To wait for another explorer.	B．To compete with others.
C．To help other explorers.	D．To make his victory recognized.

4. What might be a suitable title for the text?

A．The Antarctic Continent	B．The Impossible First
C．Traveling in Antarctica	D．An Incomplete Journey

My classmate Liu Ming succeeded in rescue a child from a burning house last Wednesday's morning. He was about to go to school while he heard a child crying. Looking around, he noticed a house burning fierce. Realizing a big fire had been broken out and a child was in danger, he called the police immediately. But he rushed into the burning house - searching for the crying child. The moment Liu Ming rushed out for the burning house with the trapped child, the house falls down. Liu Ming has set good example for us and we should learn from her heroic deeds.

6 . Recently I’ve had two good roles on television. But when I was just getting started in theater work 17 years ago, I never thought I’d make it. Back then I was recovering from surgery and had been off work for six months. Even worse, as a single mother with three youngsters, I had no place to live in. I felt hopeless.

One Sunday morning I saw actor Robert Young on the television talking about his faith: Believe yourself! If we confidently take that first step, well take the next, until we reach our goal.

The first step was scary. After I went working part-time, I looked for an apartment. The ones I saw were either too expensive, or I couldn’t raise my children in them. I knew a house, not an apartment, was more suitable for me. However, after seeing several houses, my confidence was shaken. I found two seemed right, but when I was about to make an offer, someone else had ordered.

I remembered a saying, “When one door closes, a better one opens.” I wouldn’t just sit staring at the closed one but got up and struggled on. In a real estate (房地产) agent, I found a small house with proper price. To buy it, I had to borrow $ 3,000 for a down payment and get a mortgage (按揭). Common sense argued that a mortgage for a single mother working part-time was impossible. But I had enough self-confidence without following common sense.

After getting the house, my new self-confidence grew. Later , when I began filling small parts in television productions, that self-confidence showed. I'd always played the role as the director wanted. Now I find myself freer to interpret (演绎) it.

Self-confidence has made it through life. Trouble can be scary at first, but each time I take that step, I believe I will win the next.

7 . If you're like most pet owners, you probably talk to your pet all the time, even if you feel a little silly about it. But experts say your pet is actually “talking” back to you, even if you don't totally understand what they're' trying to say. Cats and dogs are extremely cognitive(认知的)beings and communicate with us all the time. A pet's cognition starts developing as soon as they're born and changes with age just like humans.

What is cognition?     1     It involves memory, the ability to deal with a changing environment and interacting with other individuals. Just like people, pets go through age-related cognitive changes, but these changes can often be confused with physical issues because they look similar.

How do you notice cognitive changes?     2     The following could be clues that your pet's cognition is off.

●They appear confused or cannot remember their training. Forgetting tricks or house training can be clues.

●    3     If your pet is showing less affection, it may be a sign that they're having trouble remembering people.

●Aggression. Sudden aggression toward strangers and even family members can be a sign that they've lost the ability to recognize people.

● Lack of appetite.     4    

●Change in sleep-wake cycle. Sleeping all day and staying up all night is not normal behavior and may be a sign of something more.

Giving your pet good nutrition is extremely important.     5    Certain nutrients like antioxidants(抗氧化物) from vegetables, along with vitamins and fats from coconuts, can all help boost an aging dog's brain. And, if your pet is over the age of 7, it's time to start looking for a senior brand of food. If your pet is exhibiting strange behavior, talk to your vet(兽医) about what next steps you can take.

A．Lack of interaction or affection.

B．They aren't interested in anything.

C．It's not always easy to notice these.

D．Pets have cognition the same as human.

E．Nutrition helps bridge the gap for cognition as your pet ages.

F．Your pet may forget where their bowl is or when to expect food.

G．Cognition is the ability to learn something and do complex tasks.

8 . A new phone app uses shaking from smartphones to warn people about earthquakes. The new app is called MyShake, which is the work of four researchers at the University of California, Berkeley.

Smartphones are equipped with accelerometers （加速器）.MyShake uses phone accelerometers to measure seismic （地震的）activity. It has been programmed to know the difference between normal activity and earthquake movement. The software developers say their app is right 93 percent of the time. A smartphone sends seismic information to the app developers. If the developers receive several warnings from one area it recognizes that an earthquake may be taking place or will take place soon. Using information sent from the app, the network then judges the location and strength of the quake in real time. MyShake can record 5. 0 earthquakes at distances of 10 kilometers or less.

MyShake uses very little power according to its developers. Only when seismic activity is sensed by the app does it become active and sends data to the network. The app works best when your phone is resting on a flat surface like a table.

The developers hope that MyShake can add to information collected by the US Geological Survey. That US agency has created the Earthquake Early Warning System also known as the EEW. The EEW has used sensors for measuring quakes in many areas. In places where no such equipment exists MyShake may be the only method of early quake detection（发现）. The app also shows ways to stay safer during an earthquake. The developers say it will become more effective as more people use it.

The developers say they hope to add a feature that will warn people about a possible tsunami（海啸）after an earthquake.

1. What's the main idea of the first two paragraphs?

A．What seismic activity is,

B．What MyShake is and how it works.

C．When accelerometers record earthquakes.

D．MyShake plays an important role in reporting earthquakes.

2. What can we learn from the passage?

A．Only when smart phones are placed on a flat surface can it work.

B．The smart phone can warn its owner when it senses an earthquake.

C．MyShake can quickly send seismic information to the app's developers.

D．MyShake can sense the difference between normal activities and earthquakes every time.

3. What probably will the app developers hope to do next?

A．To better the EEW.

B．To combine the EEW and MyShake.

C．To add its function to warn the possible damage after an earthquake.

D．To use the information by the U.S. Geological Survey to better MyShake.

4. Which of the following could be the best title of the passage?

A．MyShake will Be Used in Earthquakes

B．MyShake Is on the Way to Predict Earthquakes

C．MyShake Has Been Developed to Predict Earthquakes

D．MyShake Makes Earthquake Prediction More Accurate

9 . Have you ever wondered why certain pop songs just make you feel so good? Researchers studying the question found that uncertainty and surprise give listeners the most pleasure. The study included 80,000 chords（和弦）in 745 pop songs between 1958 and 1991.

Each song was stripped of its melody（旋律）and lyrics（歌词）so that only chords were left and the results couldn^’t be misunderstood by other imaginations of the songs that listeners might have had.

They found two things. Listeners got great pleasure from unexpected chords when they knew what would happen. However, they still found it pleasant to hear familiar chords when they did not know what would follow.

Vincent Cheung, the lead researcher, said, "Pleasant songs are likely those which keep a good balance（平衡）between knowing what is going to happen next and surprising us with something we did not expect. Understanding how music starts our pleasure system in the brain could explain why listening to music might help us feel better when we are feeling blue.”

Cheung told CNN that pleasure in music is connected to expectation. The study before had looked into the effects of surprise on pleasure, but his team's study also paid attention to the uncertainty of listeners' expectations.

1. What does the underlined word in Paragraph 2 mean?

A．Removed.	B．Added.
C．Played.	D．Recorded.

2. How did the researchers do the research?

A．They listened to lots of pop songs.

B．They focus on the chords in popular songs.

C．They imagined the songs that can make people pleased.

D．They found lots of songs and then compared each other.

3. What can we learn from the passage?

A．Pleasant music can explain human nature.

B．Listening to music might make people feel blue.

C．Music can improve the pleasure system of people.

D．Pleasant music comes from the balance of expectation and surprise.

4. What is the difference between Cheung's study and others' study?

A．His study only paid attention to chords in songs.

B．His study focused on the effects of surprise on pleasure.

C．His study took time to how music starts the pleasure system.

D．His study paid attention to the uncertainty of listeners' expectations.

10 . Experts from MIT have found means to incorporate (加入) electronic sensors into fabrics, which can help to create shirts or other garments that could be used to monitor vital signs such as temperature and heart rate. The sensor-embedded garments can be customized to fit close to the body of the person wearing them.

“We can have electronic parts or lab-made electronics embedded within the textiles that we wear every day, creating comfortable garments,” says Dagdeviren, an professor at MIT. His group set out to create garments more similar to the clothes we normally wear, using a fabric that has removable electronic sensors in it.

“In our case, the textile is not electrically functional. It’s just a passive element of our garment so that you can wear the devices comfortably during your daily activities,” Dagdeviren says. “Our main goal was to measure the physical activity of the body all from the same body part, without requiring any fixture or any tape.”

The electronic sensors consist of long flexible strips. These channels have small openings that allow the sensors to be exposed to the skin. For this study, the researchers designed a shirt with 30 temperature sensors and an accelerometer(加速度计) that can measure the wearer’s movement, heart rate, and breathing rate. The garment can then transmit this data wirelessly to a smartphone.

This kind of sensing could be useful for personalized telemedicine, allowing doctors to remotely monitor patients. “You don’t need to go to the doctor or do a video call,” Dagdeviren says. “Through this kind of data collection, I think doctors can make better assessments and help their patients in a better way.”

Last summer, several of the researchers spent time at a factory in Shenzhen, China, to experiment with mass-producing the material used for the garments. “From the outside it looks like a normal T-shirt, but from the inside, you can see the electronic parts which are touching your skin,” Dagdeviren says.

1. Why do MIT researchers make sensor-embedded garments?

A．To complete their academic tasks.

B．To transform patents for benefits.

C．To create garments with medical functions.

D．To satisfy customers’ personal need for fashion.

2. What is the main function of the electronic sensors?

A．Monitoring wearers’ behavior.	B．Making the skin fully exposed.
C．Adjusting wearers’ body temperature.	D．Collecting and transmitting health information.

3. What do we know about the sensor-embedded garments?

A．They will bring convenience to patients.	B．They could be in mass-production soon.
C．They might lead the new fashion.	D．They may take the place of doctors.

4. What can we infer about wearing a sensor-embedded garment according to Dagdeviren?

A．It’s fashionable.	B．It’s skin-friendly.
C．It’s eco-friendly.	D．It’s awkward.
