【推荐1】Because of a lack of trained lifeguards to watch over swimming pools, a team of scientists from Germany has developed an underwater robot to help lifeguards in rescuing (救援) swimmers in emergencies.
According to scientists, there are some typical postures that you can use to recognize when someone is in danger. The robot has been tested in a variety of settings including indoor pools and open water. If swimmers’ movements are consistent with drowning (溺亡), the information of the drowning person will be sent out, which is stored in a docking station on the pool floor, and it will be released by a signal from the monitoring cameras. Once the robot receives the signal and reaches its destination, it will carry the endangered person to the surface. What’s more, the robot is designed with a set of moving parts to keep the lifeless person from sliding down as the robot surfaces.
When the robot is tested at lakes and other outdoor settings, drones (无人机) took on the task of the monitoring cameras. For rescues in swimming lakes where the visibility is limited, the underwater vehicle must be equipped with acoustic sensors (声音传感器). Sound wave echoes can be used to determine people’s positions so precisely that the robot can autonomously head for the target person and pick them up. When the robot is informed of an emergency (紧急情况), a signal will warn the team immediately.
“The current system is 90 centimeters long, 50 centimeters high, and 50 centimeters wide and looks like an underwater submersible that might be used for exploring ship wrecks. The central innovation (创新)of the system is the side folding wings that fix lifeless people on a stretcher without injuring them. To bring them to the surface of the water, balloons are filled with a total of 15 to 20 kilos of buoyancy (浮力).
The research team are still doing research on the robot, aiming to make future versions smaller, lighter and less expensive. At present, a patent has already been filed for the aquatic robot. In modified versions, it can take on further tasks—such as offshore and dam wall (坝墙)inspections or being used to monitor the health of fish in fish farms.

Several large companies have begun creating paper bottles to replace glass and plastic ones. Paper bottles aren’t quite ready to go yet, but you may see them appearing on shelves over the next few years.
Companies which sell liquids* like drinks or shampoo need lots of bottles. Usually, these bottles are made of plastic or glass. But caring more about the environment, many companies have begun working to develop paper bottles.
Paper bottles have many advantages. Perhaps the most important is that they should be easy to recycle. and paper bottles are lighter than glass or plastic ones, meaning they’ll need less energy to produce and to move around. Since paper is soft and easy to mold*, companies can design their bottles to take almost any shape they choose.
But paper bottles aren’t perfect. Most paper bottles use water pulp, meaning trees need to be cut down to make the bottles. That could harm animals and others who depend on the forests. There’s still lots of testing to be done before paper bottles can replace glass or plastic ones. Companies will need to see how long liquids can be stored in the bottles, and make sure the bottles don’t affect the taste.
But with so many companies working together, it’s sure that we can expect to see paper bottles on store shelves in the near future.
1. Why have many companies begun to develop paper bottles?| A．To reduce the cost. | B．To make more money. |
| C．To become more famous. | D．To protect the environment. |
| A．they may do harm to the forests | B．they are lighter and softer than glass |
| C．they are not as strong as plastic ones | D．they are more expensive than glass ones |
| A．Unclear. | B．Worried. | C．Confident. | D．Surprised. |
| A．Paper Bottles May Produce New Problems | B．Companies Work to Develop Paper Bottles |
| C．Will Paper Bottles Replace Plastic Ones | D．Are Paper Bottles Better than Plastic Ones |
【推荐3】Beep…beep…There went the bell! Robbie opened his eyes. It was 5:00 p.m. And it was time for him to do something.
Robbie looked out of the window. It was still snowing heavily and there was ice on the window. It was a cold day. Robbie got a message from his master (主人). He knew he should turn the heat (暖气) on before the family got home, and he did it.

After that Robbie had to cook dinner for the family. The first thing he did was to get the big pot in the kitchen. Then he put some water in the pot and put it on the stove. He used one of his hands to cut up a chicken and added the pieces to the water to make delicious soup. Then he got some tomatoes, cabbages and carrots to make vegetable salad.
At 8:10 in the evening, he put some bread, the chicken soup and the salad on the table. The moment he turned on the lights, the whole family came home.
“It’s warm here and the soup smells great, Victor,” Helen said to her son. “We really know how to tell Robbie what to do.” Robbie was a robot and he really helped the family do a lot of work.
