Too much work and too much wine go together like biscuits and cheese, a new international studies finds. Employees who work more than 48 hours a week are 11 percent more likely to over-consume (过渡消费) alcohol than those who work standard time, Finnish researchers say. The study looked at more than 300,000 people in Australia, Europe and North America. No differences were seen between men and women, says the study, published in the British Medical Journal.

Risky alcohol consumption is considered as more than 14 drinks a week for women and more than 21 drinks a week for men. About 20 percent of Australians drink at levels that put them at risk of lifetime harm from injury or disease. Drinking alcohol can affect the liver or cause brain damage, heart disease, high blood pressure and increase the risk of many cancers.

Study author Marianna Virtanen said while alcohol might help ease the stress of working long periods of time, risky consumption could lead to difficulties in the workplace, such as poor performance. The European Union Working Time Directive ensures that workers in EU countries have the right to work no more than 48 hours a week, including overtime. “ But many people , for example well-educated managers and professionals, work much longer hours to achieve faster promotions (晋升), salary increases, and more control over work and employment,” said Prof. Virtanen from the Finnish Institute of Occupational Health.

D. South America.

Children who spend more time outdoors may have a lower risk of becoming nearsighted, new research suggests.

In the study, researchers looked at about 1,900 schoolchildren. The scientists found that the kids who had been instructed to spend more time outdoors over three years were 23 percent less likely to develop nearsightedness during this time than those who had not been instructed to spend more time outdoors. Moreover, among the kids who did become nearsighted during the study, the degree to which their eyesight worsened was slightly smaller among those who spent more time outdoors.

The researchers selected six schools and required the children, whose average age was 7 at the start of the study, to attend one additional 60-minute class of outdoor activities during each school day for three years. The parents of these children were also encouraged to engage their children in outdoor activities after school, especially during weekends and holidays. The other half of the children, from another six schools, continued their usual activity patterns. After three years, 30.4 percent of the kids in the intervention(干预) group had become nearsighted, compared with 38.5 percent of the kids in the other group.

It is not clear exactly why spending more time outside would benefit children’s eyesight, the researchers said. However, some research has suggested that the higher levels of light intensity found outdoors may increase the release of the chemical dopamine(多巴胺) of the eye. In turn, dopamine is known to restrain（抑制） the type of growth in the eye that is associated with nearsightedness.

Based on the new results, the researchers recommend that children spend more time outdoors because of the potential benefits to their eyesight. However, it’s important to protect kids’ skin and eyes from UV light, which can be damaging.

1.What did the children in the intervention group do during each school day?

A. Attend an extra class of outdoor activities.

B. Continue to do their usual activities.

C. Spend one hour in doing eye exercises.

D. Participate in outdoor activities with parents.

2.What can be inferred about the chemical dopamine?

A. It can contribute to poor sight. B. It can damage people’s brain

C. It is beneficial to eyesight. D. It means low levels of light intensity.

3.What may be discussed in the following paragraph?

A. How to design outdoor activities for kids.

B. How to prevent kids becoming nearsighted.

C. How to protect kids’ skin and eyes from UV light.

D. How to encourage kids to join in outdoor activities.

4.Which can serve as the best title for the passage?

A. The More Time Outdoors, the Better

B. Kids May See Better if They Play Outside

C. It’s Time to Engage Kids in Outdoor Activities

D. Researchers Found a Cure for Nearsightedness

I was in my first year of college, making friends and enjoying life, but then my whole world turned upside down. I had a heart attack. It felt like someone was stabbing(刺) me in the chest with a knife over and over again.

After three months of rest I went back to college, but then things took a turn for the worse. I was staying at my Nana’s house and woke up in the middle of the night with a terrible pain in my chest. I knew I was having a heart attack again.

I couldn’t even shout for help. Luckily my grandpa was going to the toilet and heard me falling out of bed. If it wasn’t for him, I probably wouldn’t be here.

The two holes in my heart were causing the problems and I needed an operation immediately to repair them. Unfortunately, the surgery didn’t go well and they only managed to repair one of the holes.

When I woke up from the operation, I had a really dry mouth and couldn’t wait to have something to eat and drink. The biggest shock of all came when I was told that I needed a heart transplant and was put on the register. The doctors were stunned(吃惊地) at how quickly heart failure came on—it usually takes years, but it took my heart less than six months to get to that stage. My whole world came crashing down, but I stayed strong. It was a choice between crying every day and getting on with my life.

As time went on, life became even harder. I hated feeling weak all the time and needing help with everything. It got to the point where I thought I would never get a new heart. I was diagnosed with depression.

Even though I thought that Christmas 2016 would be my last, I really enjoyed it and even had a good New Year. Everyone was crying for me when the clock struck midnight and they told me to keep fighting.

A week later, I got a call from the doctors saying they’d found a suitable donor(捐赠人). My wish came true and thankfully the operation went well. I spent four hours in surgery where they took out my old heart and put a new one in. When I woke up I burst out crying. I had a second chance of life.

A new eight-kilometre road is under construction that links the port area with the motorway system. It is expected to carry 20,000 trucks and cars a day, which greatly reduces the overcrowded traffic in the center of the city. As part of the project, two four-kilometre road tunnels are being built below the central area of the city, one for traffic to the north and the other for traffic to the south .The two tunnels are about 20 metres below the surface and are 12 metres wide, providing for two lanes of traffic in each direction.

In the upper part of the tunnel two air-conditioning pipes remove the waste gas of trucks and cars and keep the quality of air inside the tunnel. The lighting is at the top of the tunnel, practically at its highest point. There will also be electronic signs at frequent intervals (间隔). They show traffic conditions ahead, and can be seen clearly by drivers. The wall is made up of four main elements, which include a waterproofing covering and , on the inside of the tunnel , a concrete lining (混凝土衬砌).

Each tunnel is roughly round and the lower part of the tunnel is somewhat flat .The surface of the road lies on the base, which is made of concrete and steel. The drainage system (排水系统), just below the road surface on one side, removes any extra liquid, particularly water. In the event of fire, the fire main, which is made of steel, pipes water to many fire hydrant stations at regular intervals along the length of the tunnel. The fire main is at the side of the tunnel, and at the level of the road surface. Other systems in the tunnel will include emergency phones .

1.Each of the tunnels under construction is ________.

A. eight kilometers long and twenty metres wide

B. four kilometers long and six metres wide

C. four kilometers long and twenty metres wide

D. eight kilometers long and six metres wide

2.Which part of the tunnel in the diagram is used to pipe out extra water?
