Unfortunately, plant sounds are at too high a frequency for the human ear     3     (pick) up. Humans can only hear frequencies of up to 16 kilohertz (赫兹). Using special Al technology, scientists can now pick up sounds     4     (send) out by plants that are up to 250 kilohertz. The Al can also tell differences between different types of plant sounds.

The research     5     (do) in a greenhouse at Israel’s Tel Aviy University. Lead researcher Professor Lilach Hadany said: “Plants usually give off sounds when they     6     (be) under stress.

As artificial intelligence products steadily improve at pretending to be human, people will increasingly be put in the unsettling situation of not knowing     1     they are talking to a machine.

But there is always the desire     6    (earn) extra points at the partner’s expense. Previous work suggested people tended to distrust machines, so the scientists hoped people     7     (play) with a known robot would recognize its ability to cooperate and would     8     (eventual) get past their distrust.

“Sadly, we failed at this goal,” says Talal Rahwan, a senior author on the paper,     9     (publish) last November in Nature Machine Intelligence. “A robot was     10     (likely) to obtain cooperation than another human, even though its strategy was clearly more beneficial to both players.”

It seems that there is a long way to go before trust in robots is established.

9 . Here are this year’s four scientific discoveries that could lead to new inventions.

Discovery 1—To survive in the ocean, some animals hide themselves from the light, hoping not to be found by a predator (捕食者). However, their eyes reflect (反射) light, creating shine that can give away their location. Some tiny crustaceans (甲壳类动物) have developed a way around this disadvantage. Their eyes are covered with a sheet of special glass that effectively matches their eyeshine to the color of surrounding water. In this way, they become invisible (看不见的). This discovery might help researchers improve relative technologies in remote sensing and communications.

Discovery 2—Brown bears seldom suffer from blood clots (血栓). To find out how they do it, scientists tracked down brown bears in Sweden. They discovered one protein (蛋白质) in brown bears showed a significant seasonal change. The discovery could provide ways for preventive treatment for cancer patients and those likely to develop blood clots.

Discovery 3—Asp caterpillar venom (毛虫毒液) contains an unusual protein. When it reaches the outer surface of a cell (细胞), this protein makes a hole through the cell wall. By researching such nature, engineers could develop medicine delivery ways to get drugs (药物) inside cells where they need to work.

Discovery 4—This year, scientists found two special proteins in bowhead whales. The proteins called CIRBP and RPA2 play a role in DNA repair, making the animals unlikely to develop cancers. As a scientist says, we probably have the solution to cancer medicine out there in nature already.

10 . The daily life can be busy and at times difficult. It may sometimes feel like bringing just a little more inner peace and calmness into your life is a hopeless wish.     1     Small and smart changes can make a big difference over time. Here are some tips for finding more peace and calmness in everyday life.

Solve a problem that is weighing heavily on you. Solve your problem and release (释放) all the stress that it is creating in your life. You probably already know what to do, and you are just not doing it yet.     5     So get up from your chair and get started right now.

C．But it doesn’t have to be that way.

D．And say no if you really don’t have the time.

G．But the longer you wait,the worse the tension (紧张) inside becomes.
