1 . Smartwatches and fitness trackers (健身追踪器) have gained popularity recently. These tools can record your daily steps, heart rates, etc.     1    . If yes, it might be a sign that you’re addicted to your fitness tracker.

    2    . If you keep setting unrealistic daily goals that involve working out for too long, and if you begin to ignore friends and responsibilities to make time for your workout, then you’re most probably addicted to your fitness tracker.

It’s a struggle to overcome the addiction to fitness trackers.     3    . For example, the number in your smart watch showing how far you’ve come can give you a sense of achievement.

Of course, failing to meet your daily goal can be discouraging. You might focus on your shortcoming rather than your progress. Another problem is that you might find yourself paying too much attention to the step number rather than how your body feels.     4    .

Therefore, if you’re spending too much time looking at your smartwatch, limit your daily step count to a comfortable level.     5    . For example, concentrating on your hobbies or socializing with friends can be a great way to keep your mind on other things.

A．How can you tell whether you’re addicted to your fitness tracker?

B．Actually this addiction to step count can be risky, mentally and physically.

C．Don’t overuse your smartwatch.

D．However, do you find yourself checking your steps and heart rates too often?

E．After all, reaching a daily step count can be so appealing.

F．Besides, you can find other things to do that don’t involve checking your fitness tracker.

G．It doesn’t covey what you’re really feeling.

3 . Art and science may seem like opposite things. One means the creative flow of ideas, and the other means cold, hard data-some people believe. In fact, the two have much in common. Now, a study finds art can help students remember better what they have learned in the science class.

Mariale Hardiman, an education specialist at Johns Hopkins University, noticed that students who used art in the classroom listened more carefully. They might ask more questions. They might volunteer more ideas. What’s more, students seemed to remember more of what they had been taught when their science lessons had involved(涉及) art. To prove that, Hardiman teamed up with some researchers and six local schools.

In the experiment, the researchers worked with teachers in 16 fifth-grade classrooms. They provided traditional science lessons and art-focused ones. In a traditional science class, for example, students might read aloud from a book. In the art-focused one, they might sing the information instead.

The team randomly assigned(随机分配) each of the 350 students to either a traditional science classroom or an art-focused one. Students then learned science using that way for the whole unit-about three weeks. When they changed to a new topic, they also changed to the other type of class. This way, each student had both an art-focused class and a traditional one. Every unit was taught in both ways, to different groups of students. This enabled the researchers to see how students did in both types of classes.

The team found that students who started off in a traditional class performed better after they moved into an art-focused class. But those who started off in an art-focused class did well even when they went back to a traditional science class. These students appeared to use some of the art techniques(技巧) after going back to a traditional class. Classroom teachers reported that many students continued to sing the songs that they learned after finishing the unit. “The more we hear something, the more we retain it,” Hardiman says. “It suggests that the arts may help students apply creative ways of learning on their own.”

4 . Thirteen-year-old Kaylee has a lot of friends — 532, actually, if you count up her online friends. And she spends a lot of time with them.

But is it possible that Kaylee’s online friendships could be making her lonely? That’s what some experts believe. Connecting online is a great way to stay in touch, they say. However, some experts worry that many kids are so busy connecting online that they might be missing out on true friendships.

Could this be true? During your parents’ childhoods, connecting with friends usually meant spending time with them in the flesh. Kids played Scrabble around a table, not Words With Friends on their phones. When friends missed each other, they picked up the telephone. Friends might even write letters to each other.

Today, most communication takes place online. A typical teen sends 2,000 texts a month and spends more than 44 hours per week in front of a screen. Much of this time is spent on social media platforms (平台).

In fact, in many ways, online communication can make friendships stronger, “There’s definitely a positive influence. Kids can stay in constant contact, which means they can share more of their feelings with each other,” says Katie Davis, co-author of The App Generation.

Other experts, however, warn that too much online communication can get in the way of forming deep friendships. “If we are constantly checking in with our virtual words, we will have little time for our real-world friendships.” says Larry Rosen, a professor at California State University. Rosen also worries that today’s kids might mistake the “friends” on the social media for true friends in life. However, in tough times, you don’t need someone to like your picture or share your blogs. You need someone who will keep your secrets and hold your hand. You would like to talk face to face.

1. What is the purpose of the first paragraph?

A．To summarize the text.	B．To tell about true friends.
C．To bring up a discussion.	D．To encourage online friendship.

2. What does the underlined part “in the flesh” mean in Paragraph 3?

A．In person.

B．In advance.

C．In any case.

D．In full measure.

3. What is Katie’s attitude towards online communication?

A．Worried.

B．Positive.

C．Confused.

D．Unconcerned.

4. What view does Rosen hold?

A．It’s wise to turn to friends online.

B．It’s easier to develop friendships in reality.

C．Social media help people stay closely connected.

D．Teenagers need focus on real-world friendships.

6 . It happens every spring. Flowers suddenly come out everywhere on the same day, as if they made an appointment with one another. But how exactly do plants “know” when to flower?

It is a question that has puzzled biologists for years. But according to Science Daily, a US research group may have finally answered it —the secret lies in a protein (蛋白质) called FKF1. This allows plants to sense the differences in day lengths so that they can tell the seasons are changing.

Researchers discovered the FKFI protein when they were studying a plant called Arabidopsis. They found that the FKFI protein is a photoreceptor (感光器). This means it is sensitive to, and can be activated by sunlight.

“Plants produce this protein every day in the late afternoon throughout the year. If there is no light at this time, for example, in winter when the sun goes down early, the protein won’t be activated,” explained Takato Imaizumi, the leader of the study. “But when spring comes and the days get longer, the FKF1 protein can be activated by daylight and the plants ‘know’ it is time to flower.”

Although researchers have only studied how the FKF1 protein works in the Arabidopsis, they believe that the process is similar in other plants, including crops like rice and wheat. This could be useful to the agricultural industry in the world.

1. The underlined word “activated” in paragraph 3 probably means__________.

3. This text may be taken from__________.

A．a travel brochure	B．a science magazine
C．a medical magazine	D．a personal journal

7 . Earthquakes are something that people fear. There are some places that have few or earthquakes. Most places in the world, however, have them regularly. Countries that have a of earthquakes are usually quite mountainous.

The most-talked-about earthquake in the United States was in San Francisco in 1906.Over 700 people died in it. The strongest one in North America was in 1964. It happened in Alaska.

Strong earthquakes are not always the ones that kill the most people. In 1755, one of the strongest earthquakes ever recorded was felt in Portugal. Around 2,000 people died. In 1923, a very strong earthquake hit Tokyo, Yokohama area of Japan. 140,000 people died. Most of them died in fires which followed the earthquake.

One of the worst earthquakes ever was in China in 1976. It killed a large number of people. The worst earthquake ever reported was also in China, in which 830, 000 people were killed. This earthquake happened in 1556.

Earthquakes worry people a lot. The reason is that we often do not know when they are coming. People cannot prepare for them beforehand.

9 . The Double Ninth Festival falls on the ninth day of the ninth month in the Chinese lunar calendar. According to tradition, we should celebrate the festival by going mountain climbing. How many people today still keep this tradition?    1    However, they are an important part of Chinese culture, and we must protect and maintain them.

    2    The Dragon Boat Festival, for example, is celebrated in honour of Qu Yuan. By celebrating the Dragon Boat Festival with rice dumplings and dragon boat races, the story of Qu Yuan is passed down from generation to generation. Promoting traditional festivals helps spread knowledge about the past of our country. Moreover, traditional festivals enable us to learn more about fine Chinese values. Many festivals, such as the Mid-Autumn Festival, have a family-centred message at their heart.    3    With the celebrations of these festivals, younger generations learn to honour fine Chinese values.

Finally, traditional festivals area source of national pride and help shape (塑造) our national identity. For example, we celebrate the Hanshi Festival and the Lab a Festival with unique customs, and these shared experiences bring us together as a people.    4    

Traditional festivals have been passed down to us from previous generations. It is the duty of every one of us to protect them for generations to come.    5    We may even lose the festivals which belong to us.

A．Many young people celebrate western festivals.

B．Traditional festivals can help develop our economy.

C．Traditional festivals teach us a lot about our nation’s history.

D．People will come back home even if they live very far away.

E．Traditional festivals tell us who we are and fill us with pride in being Chinese.

F．In modern society, many traditional Chinese festivals are becoming less and less popular.

G．If we don’t pay much attention to these traditional festivals, some customs may fade away.

10 . Ludwig van Beethoven was a German composer. In his twenties, he had been very famous for his skills on the piano, but then he began to lose his hearing. Beethoven thought about giving up, but in the end he continued to write music. He carried on with the composition until his death in 1827. He composed more than 130 musical works, including his Ninth Symphony (交响曲) .

One day in February 1824, his Ninth Symphony was finally completed. Writing the piece had taken several years. A she proudly signed his name at the bottom of the page, Beethoven tried to imagine how people would respond when they heard it for the first time. Before the performance, the backstage atmosphere at a very famous theatre in Austria was anxious. Beethoven was afraid that the performance would be a disaster. After all, what use is a conductor who could not hear his orchestra (管弦乐) — even if he has a talent for music?

The audience didn’t hesitate to applaud (鼓掌) loudly as the famous composer walked out on to the stage. The theatre’s musical director, Michael Umlauf, joined him and together the two men took charge of the orchestra. For more than an hour, Beethoven jumped about in front of the orchestra, waving his arms wildly in the air, and madly turning the pages of his score (乐谱).

As the symphony came to an end, the audience jumped to their feet, clapping, cheering and waving their hats. But Beethoven continued conducting, his head buried in the score. It was not until Caroline Unger, one of the singers, took his arm and turned him to face the audience that the great man realized his symphony was a victory.

Later, Caroline remembered that Beethoven was not the only one who got a surprise. “The audience was shocked as well,” she said with abroad smile. “Most of them had no idea that he lost his hearing. The one person in the room who didn’t hear the symphony — and never would — was the very man who composed it.”
