A special tea picker has been operating at a West Lake Longjing tea plantation in Hangzhou recently. It is the world's first tea-picking robot. The robot uses two mechanical arms to move back and forth as it searches 【小题1】 tea buds （芽）. When it locates one, it uses a pair of scissors and a suction （抽吸） device 【小题2】 (attach) to the end of its arm to cut and collect the tea buds. It 【小题3】 (equip) with a pair of 3D eyes that can 【小题4】 (automatic) identify tender tea leaves through artificial intelligence technology. People firstly take many photos to tell the machine about the targets 【小题5】 it can pick, and when the photos are enough, the machine will learn by 【小题6】 ( it). The technology is also constantly improving. It has now been upgraded to the fifth generation, and it takes just 1. 5 seconds 【小题7】 (pick) a tea bud, with an 【小题8】 (accurate) rate of 86 percent.

Ruan Jianyun, a tea expert, said, "We still have two problems. One problem is the efficiency and quality of tea picking, and 【小题9】 other is the cost of the machine."

In recent years, mechanization has been widely applied in the tea production industry. However, the picking of high-quality tea still 【小题10】 (rely) on human labor.

Mobile phone technology is quickly changing the way the world operates. Today, we talk about two new projects involving mobile health, also 【小题1】(know) as m-health.

Doctors and technology experts in London are developing a new way 【小题2】(test) for AIDS infections. People place the test paper they 【小题3】(offer) in a small device containing a computer chip. Then the place they device in their mobile phone for testing. Within minutes, they receive information telling them 【小题4】they are infected with HIV. And they receive advice on 【小题5】to do next.

Claudia Estcourt, a research team leader, says, “This isn't designed to replace traditional clinics. This is really opening testing up to people 【小题6】might find it embarrassing or difficult to get into their clinic. And this might be a much quicker, easier choice for them—that they can be sure to get very accurate results.”

Researchers at the University of Canada are studying a mobile phone system that may help people 【小题7】diabetes control their blood pressure. The blood pressure readings collected by the patients at home are then sent to a health-care monitoring system.

Patients receive a mobile phone message telling them how they are doing.【小题8】blood pressure is too high, they are advised to make an 【小题9】 (appoint) with their doctors. Several high readings will cause the system to【小题10】(automatic) contact the doctor.
