1 . Sleeping in a noisy room isn’t only distracting (使人分心的), and it can also harm your health. Although researchers have known for decades that longterm loud noises can harm us, it’s only recently become recognized as a widespread problem.
In a new review of previously published studies, researchers from Germany and Denmark took a look at the ways in which noises, such as an airplane passing by or jackhammer digging in the ground, can affect our hearts. Perhaps the most obvious impact of a loud sound while you are sleeping is that it can wake you up. But, even if you don't remember hearing the noise or you don’t physically get out of bed, it can disrupt you in ways you may not realize.
“Noise is not just causing annoyance, but it actually makes us sick,” said Dr. Thomas Münzel, a professor at Johannes Gutenberg University Mainz. “Regardless of where the sound is coming from, if it gets louder than 60 decibels (分贝),it can increase the risk of heart disease.”
When our body hears these noises, it reacts with a stress reaction. In this case, these sudden and unexpected noises cause hormones(荷尔蒙) to speed up and eventually damage the heart. Although the chance that a single noise will affect you is unlikely, it’s the continuous exposure (接触) to the sound that can finally affect you.
“But our heart health isn’t the only cause for concern. Long-term noise may also raise the risk of type 2 diabetes (糖尿病), depression, and anxiety disorders,” he warns. In the future, Münzel plans to examine how noises from cars, planes, and other vehicles affect the brain. But despite the amount or the depth of research he conducts, it’ll take the help of politicians to improve the effect of noise on our health.
“Politicians have to take into account, in particular, the new findings,” Münzel said, “As for aircraft noise and airports, it is important to make new laws and set new lower noise limits that protect people living close by the airport instead of the owners of the airport.”

2 . People tend to cut corners and allow trusted workmates to do their work when working as a team. Now researchers have found that the same thing happens when humans work with robots.
Dietlind Cymek at the Technical University of Berlin in Germany and her colleagues designed an experiment to test whether humans would put in less effort when they think that their personal contribution to a task won’t be noticed.
In the experiment, the researchers asked a group of 42 people to examine images of circuit boards (电路板) for errors using a computer that tracked their work. Half of them looked at boards that had already been checked by a robot, and half were told that they were the only ones responsible for quality control.
People working in partnership with the robot caught fewer errors, after they had already seen that the robot had successfully flagged lots of errors.
The researchers say such teamwork could lead to a drop in motivation if individual effort isn’t visible and warn that there could be safety risks if teams of people and robots work on safety-related tasks in the same way.
Kathleen Richardson at De Montfort University in Leicester, UK, says it is fine to use robots as long as they are effective, but that they should be considered tools rather than workmates or team members. “It just strikes me that workers think when a tool can do something, they let it,” says Richardson.
This is probably down to poor management style, in which individual work isn’t recognised. “I bet you if there was an motivation behind it, and if the humans could get extra pay for spotting errors in the circuit boards, then they’d put a bit more effort into it,” she adds.

Should We Help Strangers?
Recently our class had a discussion about whether we should help strangers. Different students have different opinions.
