2 . Austrian company Tec-Innovation recently disclosed smart shoes that use sensors to help people suffering from blindness or vision damage to detect obstacles up to four meters away.

Known as InnoMake,the smart shoe may become a possible alternative to the decades-old waking stick that millions of people depend on to get around as safely as possible. The currently available model relies on sensors to detect obstacles and warms the wearer via vibration and an alert sounded on a Bluetooth-linked smartphone. "Sensors on the toe of the shoe detect obstacles up to four meters away.The wearer is then warned by vibration and/or acoustic (听觉的) signals.This works very well and is already a great help to me personally,"Markus Raffer, one of the founders of Tec-Innovation, himself visually damaged,said.

That sounds impressive enough, but the company is already working on a much more advanced version that combines cameras and artificial intelligence to not only detect obstacles but also their nature."Not only is the warming that I am facing an obstacle relevant, but also the information about what kind of obstacle I am facing. Because it makes a big difference whether it's a wall, a car or a staircase, Raffer claimed.

The advanced system is fix in the front of the shoes, in a waterproof and dust proof case. It is powered by a heavy-duty battery that can last for up to one week, depending on use.The battery can be charged in just three hours, using a USB cable.

The next step for Tec-Innovation is to use the data collected by its system to create a kind of street view navigation map for visually damaged people.

"As it currently stands, only the wearer benefits from the data the shoe collects as he or she walks. It would be much more sustainable if this data could also be made available to other people as a navigation aid,"computer scientist Friedrich Fraundorfer explained.

1. InnoMake aims to

A．collect data as blind people walk

C．clear obstacles in streets for blind people

D．help blind people walk around more safely

2. What is Paragraph 2 mainly about?

A．The way that InnoMake works.

B．More wearers will benefit from innoMake.

C．There's still space for InnoMake to improve.

D．Data should be shared among more wearers.

3 . Butter coffee, also sometimes referred to as bulletproof coffee, is almost exactly what it sounds like. Take a cup of black coffee and drop a bit of butter into it. Though the name doesn't indicate this, you also need to add a little coconut oil. Upon hearing about butter coffee, people generally all into one of two camps. Either you are disgusted at the notion and determine never to try it or you are more laid-back and think "Sure, why not?"

If you are still puzzled about why this drink exists, here's a bit of backstory. In 2009, Dave Asprey, a businessman, launched and trademarked Bulletproof coffee. He got the idea during his travels in Tibet, where yak butter (酥油) tea is common. He marketed and sold the concept as a low-carbon, high-fat breakfast alternative that would help people lose weight and be energized.

Despite all of Asprey's claims, there are not many benefits to butter coffee, especially if anyone skips meals and replaces them with the drink. While cutting out carbohydrates (碳水化合物) may be good for people with type2 diabetes, a low-carbon diet is usually only recommended for a short period of time. And though the fat from the butter may keep you feeling full for a while, there are a number of downsides to adding a couple of tablespoons to your morning coffee.

Doctors point out that the amount of fat in butter coffee is higher than most recommended daily amounts. Additionally, a breakfast of butter and coffee does not contain nutrients that are essential to a healthy diet.

1. What does the author mean by "two camps" in the first paragraph?

A．The campsites where Asprey tried yak butter tea.

B．The areas where one can buy fresh butter coffee.

C．The two versions of butter coffee that are popular.

4 . Take a bottle of soda, and shake it really hard. Gas will form inside, causing a buildup of pressure. Twist the cap off. Pressure will be released from the bottle, and soda will shoot everywhere.

    1     Pressure builds up inside a volcano as gas forms in magma (岩浆), which is hot liquid rock beneath the surface of the earth. Gas bubbles in the volcano need to escape. When a volcano erupts, magma is pushed up through the opening with great force. When magma reaches the earth’s surface, it’s called lava (熔岩).

Some volcanic eruptions are explosive. Lava shoots into the sky. Gas and hot pieces of rock and ash are also released. The intensity of an eruption depends on a few factors. One is the magma’s temperature. Another is the magma’s thickness.     2    

Volcanic eruptions can cause other natural disasters. These include landslides, mudslides, earthquakes and tsunamis. Volcanoes can be destructive.     3     The Hawaiian Islands were created by the eruptions of large low-lying volcanoes which are made up of layers of hardened lava.

    4     Ash from volcanoes adds helpful minerals to soil. This helps plants grow strong. Healthy plants produce oxygen for humans and animals to breathe. Volcanoes also remove heat from the earth’s interior (内部), which helps keep our planet cool.

In recent years, a new benefit of volcanoes has surfaced.     5     Their measures involve using the heat beneath the earth’s surface to produce electricity.

Volcanoes may be unpredictable. However, as we learn more about how they work, they will become even more important to life on the earth.

A．However, they can also create new land.

B．Volcanoes can become more dangerous.

C．A volcanic eruption works much the same way.

D．Scientists are using volcanoes to help power cities.

E．The amount of gas trapped inside is also an important one.

F．Volcanoes are threatening the life of people across the world.

G．Volcanoes have played an important role in shaping the earth.

5 . 阅读下面短文，在空白处填入1个适当的单词或括号内单词的正确形式。

Inside the greenhouses of a modern agricultural base in Jiangmen, Guangdong Province, grow hydroponic vegetables,     1     （range）from ordinary ones to varieties rarely seen on the market. Inside the pools seven species of fish are raised, living with the vegetables     2    （harmony）.

“Fish farming without the need to change the water and growing vegetables without the need to fertilize. This is the fish-vegetable symbiosis system." said Fung Leung, the     3     (found) of the project. "All the vegetables are free of pesticide residues, because once pesticides and fertilizers     4     (apply), the fish will die.”

Since starting their business in Jiangmen, Leung     5     (witness) the development that has taken place in the city and also in the Greater Bay Area. "Better transportation and     6    frequent exchanges between the mainland and Hong Kong have also helped us reduce transport costs,”   he said.

In 2019 he established a second project in Jiangmen, which covers     7     area of 26.67 hectares and is capable of producing 8,800 tons of vegetables every year for Hong Kong.

“Food safety is what people are most     8     (concern) about in their pursuit of quality life. Local agriculture in Hong Kong is unable to satisfy the city’s demand for such products in terms of scale and quality. Vegetables     9     (supply) to Hong Kong from the mainland must meet very high standards throughout the whole process of production and processing," said Leung. According to him, it is promising business opportunities such as these     10     have convinced him to focus on growing organic vegetables in the long term.

6 . Test anxiety is a feeling someone might have in a situation where performance really counts. It can bring on “butterflies," a stomachache, or a headache.     1     A student with strong test anxiety may even feel like he might throw up. Feeling ready to meet the challenge, though, can keep test anxiety at a manageable level.

    2     Although a little test anxiety can be a good thing, an overdose of it is another story. If a test gets you so stressed that your mind goes blank, then your level of test anxiety probably needs some attention. Your teacher or a tutor can be good people to talk to when test anxiety gets to be too much to handle.

Watch what you’re thinking. If expecting to do well on a test can help you relax, what about if you expect you won’t do well? Watch out for any negative messages you might be sending yourself about the test.     3    If you find yourself thinking negative thoughts, replace them with positive messages. Not unrealistic positive messages, but ones that are practical.

Accept mistakes. Another thing you can do is to learn to keep mistakes in perspective — especially if you’re a perfectionist. Everyone makes mistakes, and you may have even heard teachers refer to mistakes as “learning opportunities.”     4    

Take care of yourself. It can help to learn ways to calm yourself down and relax when you’re tense or anxious.     5     Practicing breathing exercises regularly helps your body see these exercises as a signal to relax. And, of course, taking care of your health can help keep your mind working at its best.

A．Ask for help.

B．Use stress to your advantage.

C．They can contribute to your anxiety.

D．Some people might feel shaky as they wait for the test.

E．Learning to tolerate small failures and mistakes is a valuable skill.

F．They find their test anxiety eases when they start to study more regularly.

G．For most individuals, this might mean learning a simple breathing exercise.

7 . My father Earl was to take two-lane highways all the way from Chicago to New York. "This way," he explained, "we’ll actually see where we’re going. I hate turnpikes (收费高速公路), Virgil." There were other reasons for taking highways: no fee to pay, cheaper gas stations, and a chance to shop for food.

He had me laughing from the moment we left town. I’d never seen him in better spirits. He did imitations, told stories and made remarks to the waitresses in the restaurants we’d stopped in every three hours, highly praising their cooking skills.

Earl asked me to keep an eye out for hitchhikers (搭便车的人), so we might have someone to share the driving. My father had, however, tough standards of selecting hitchhikers. We passed teenagers, soldiers and old men, and each time Earl had a different excuse for not stopping.

Finally, my heart was filled with uncontrollable anger. "Why don’t you ever stop? It’s not fair to look at people and then not stop."

Earl looked at my face. "I don’t know. Virgil," he said. "I think the reason is that I don’t want anyone in the car. We never have any time alone and I like it with just the two of us.”

Hearing what he said, I felt tears welling up in my eyes. How wonderful, yet disturbing and unprepared I was to hear it.

We pulled in for the night some twelve hours after leaving Chicago and checked into a nameless motel. It was in this motel that my father and I spent one of the best nights of our lives. He watched TV with me for a while and he begged a pack of cards from the motel manager and did card tricks for me — a skill I had no idea he possessed. Then my father and I played a card game and we were so comforted by the game that we took the pack with us when we drove out for a late night snack of ham and eggs.

The sky was filled with stars. After turning off all the lights, we whispered to each other in bed, like boys who fear they might be overheard. I don’t remember what I said, but I was sure he was listening.

1. Why did Earl refuse to take those hitchhikers?

A．He was doubtful about them.

B．He wanted to be with his son alone.

C．They didn’t meet Earl’s tough standards.

D．He had to reach New York as soon as possible.

A．To describe a beautiful night.

B．To reflect on a difficult decision.
