Chen Chen is 8 years old. For the Spring Festival this year he was given an iPad as a present and never goes anywhere without it.     2     This is serious for such a young child.

Many children in China are suffering the same problem:     3     Xinhua New Agency went so far as to call the iPad the “No.1 killer of children’s eyesight.”

“There are about 30 shortsighted children coming every day,” said Hu Dali, a doctor at Guiyang Aier Eye Hospital. “Half of those children are suffering from reduced vision because they have played with mobile phones and iPads for too long.”

Experts say children’s version is not yet fully developed and their eyes get tired more easily.     4    

The iPad uses a very bright LED backlight. A user’s pupils (瞳孔) have to keep getting used to the new light levels. If children stare at an iPad screen for a long time, their eyes do not have time to rest.     5    

Experts suggest that users should hold their iPad between 40—60 centimeters away from them. The brightness of the screen should be made comfortable for children. Parents should also stop their children from using an iPad for more than one hour every day.

A．IPad use is damaging their eyesight

B．A month later his eyesight has reduced to 300 degrees

C．Children go eye bad due to the iPad

D．How an iPad influences children

E．This will make their eyesight worse over time

F．It does harm to their eyesight

G．This means the iPad has a greater effect on their eyes

5 . Recent research confirms what our farming ancestors have known for centuries about hedges (树篱). They conserve precious soil by acting as windbreaks and absorbing rainwater that would otherwise wash it from the fields. And hedges store carbon, putting them in the front line of our bi d to tackle the climate crisis.

However, hedges have had a tough time in the poor countryside, with farmers encouraged to tear them down in pursuit of maximum production and larger field s to accommodate ever-larger machinery. What’s more, some hedges have been ignored. If left to their own devices, they’ll eventually become a line of trees. Some hedges each year lose their structures and fail to fulfil the primary duty as a barrier. Around a half of the nation’s hedges have disappeared in the past century.

There are signs that “the tide is turning”. The search for net zero has aroused many organizations’ interest in the humble hedge’s role as a carbon sink. The Climate Change Committee is recommending a 40 percent increase in hedges: an additional 200,000 km. Such recommendations are starting to drive policy. Cash-pressed farmers will be encouraged to create new hedges and improve their management of existing ones under the new Environmental Land Management Schemes, which will replace many of the existing agricultural support payments in coming years. Meanwhile, initiatives such as Close the Gap, led by the Tree Council, is providing funding and support to plug the gaps in existing hedges with new planting. There’s even an app to help time-pressed farmers do a quick survey to spot where their hedges need some help.

This is a good time for hedges. Take some of the most pressing challenges facing the countryside, and indeed, the world as a whole — the climate crisis, soil erosion (侵蚀), insect attack and wider biodiversity loss — and hedges are part of the solution.

6 . 阅读下面材料，根据其内容和所给段落开头语续写两段，使之构成一篇完整的短文。

Today was Sunday, so I was in no hurry to get out of bed. As I rolled over and stretched, I heard my father shouted, “Oh, dear, fire!” There was unmistakable urgency in his voice. Upon hearing that, I got up and hurried downstairs. And my mother who was preparing breakfast also stopped cooking immediately. My father showed us a video shot by some witness, where we saw a fire inside a building. My mother stood beside him and shook her head.

“What a pity! Is it local?” my mother asked. As a policeman, my father had a keen observation ability. “It’s your hospital!” he watched the screen carefully and said in surprise.

It turned out that a building of the hospital where my mother worked as a head nurse was on fire. We found out later that an old wire first caused the building to catch fire and it began to spread. The camera captured the firefighters’ figures in black and orange uniform as they aimed endless streams of water at the fire.

“I have to get there,” said my mother, feeling anxious. My father and I offered to go with her. She threw on uniform and drove to the site.

Luckily, the fire didn’t spread to the building where my mother worked. After making sure that it was safe, we came to my mother’s office. My mother’s co-workers came to the office off and on as well. They were horrified at the sight of the next building but still thought about how to help.

Through a front window, I suddenly saw the rows of medical records in the next building, and I hurried to tell my mother. She felt really nervous and instantly consulted with her co-workers about how to cope. The situation was very urgent. They knew that if they waited until the firefighters who were busy evacuating (疏散) patients got here, those recordings might burn up. The fire broke out before the records, which were irreplaceable histories of their patients, could be entered into the computer.

8 . Here are five common mistakes distance learners make.

Choosing the wrong school.     1     “Diploma mill” schools charge unsuspecting students thousands of dollars for worthless degrees, whereas trustworthy schools are able to give their students diploma they are proud of. Before you enroll in an online school, do some research to find out what type of program, resource and support will be provided.

Putting off things. Many students never finish their degrees because they lack the self-discipline and motivation to sit down and get their work done on a daily basis.     2     Many students have found it beneficial to create a deadline for receiving their degrees and set small monthly, weekly, and daily goals that will allow them to reach that deadline.

Failing to connect with their peers and professors.     3     Building meaningful relationships with your peers and professors can allow you to learn more, stay motivated, and have a way to express your own understanding of the subject matter. So stay connected through message boards, chat rooms, email, and other virtual resources.

Scaring potential employers. More and more people are recognizing the validity (有效性) of online education.     4     Some potential employers may see warning signs if you announce that you have earned your degree through the Internet. Even if you attend a famous school, avoid calling attention to the fact that your studies are done online.

    5     There’s a lot of online material available to help out students. Make sure you know where you can get the help you need. Be aware of the general resources such as virtual dictionaries, online books, and resources that relate to your specialized subject matter.

A．Paying too much.

B．Paying no attention to online resources.

C．However, be aware that it is not completely accepted by all people.

D．Many students attend an online course feeling as if it is very easy.

E．Selecting the right school is the biggest difficulty that distance learners face.

F．If you often put off your work, set some specific goals for yourself and stick to them.

G．One of the most rewarding experiences in education is learning through teamwork.
