　　***阅读理解。
　　Diamonds are considered the most famous and valuable jewel in the world.The precious stone for its great value is believed to be the symbol of wealth.Diamonds are made as a result of great volcanic heat and pressure.When a volcano is active，it sometimes explodes and causes great damage to the nearby towns.
　　However，at the same time of such a disaster，diamonds were pushed towards the surface of the earth by a number of great volcanic explosions millions of years ago.Thus，it may be very likely to find a diamond after a volcanic eruption.Besides，diamonds are also found among the sandy sandstone of certain river beds，and in a few places on the sea floor，for they were washed down the mountain sides by the rain.
　　Diamonds are very rare.There are not many places that produce such precious things in the world.During the last century adventurers from Europe went to Brazil，because they had heard that there were diamonds in the Amazon River.Many of these early diamond miners died of illness or were lost forever in the great forests.But some returned home rich.
　　The earliest known diamonds were found in India many centuries ago.The_most_recent_and_exciting_discoveries_have_been_made_in_eastern_Russia.But most of the world's diamonds now come from the Congo，from Tanzania，and also from South Africa—which has the largest diamond mines in the world.
　　1．What do we know about diamonds according to the passage?
　　A．Diamonds are always accompanied by volcanic eruptions.
　　B．Diamonds are created by volcanic eruptions.
　　C．Diamonds are considered as a sign of wealth.
　　D．Diamonds could be always found in a few riverbanks.
　　2．Which of the following is NOT mentioned as a famous place producing diamonds?
　　A．The Congo.  B．South Africa.
　　C．India.  D．Western Europe.
　　3．What can we know from the third paragraph?
　　A．Diamond mining can be dangerous for the miners.
　　B．Brazil plays a more important role in diamond mining.
　　C．The Amazon River has no large diamond mines nowadays.
　　D．Many miners returned home due to the risks in diamond mining.
　　4．What does the underlined sentence mean in the last paragraph?
　　A．Eastern Russia has been famous for diamond mining for a long time.
　　B．The diamond deposit in eastern Russia wasn't discovered until recently.
　　C．Eastern Russia is not as important as African countries in diamond mining.

　　【解题导语】本文是一篇说明文，介绍了钻石的来源和产地。
　　【段意梳理】第一至二段：钻石的产生与火山爆发有关。
　　第三至四段：钻石的产地。
　　1．C　考查细节理解。根据文章第一段第二句“The precious stone for its great value is believed to be the symbol of wealth”可知，钻石被认为是财富的象征。
　　2．D　考查细节理解。根据第三、四两段对钻石产地的介绍可知，西欧并不在有名的钻石产地之列。
　　3．A　考查细节理解。根据第三段倒数第二句“Many of these early diamond miners died of illness or were lost forever in the great forests”可知，开采钻石对采矿者来说有可能是危险的，故A项正确。第三段并未提及巴西在开采钻石方面扮演着更重要的角色，因此B项错误；C项在文中也并未提及；根据第三段倒数第二句“Many of these early diamond miners died of illness or were lost forever in the great forests”可知D项错误。
　　4．B　考查句意理解。画线句前一句提到已知的最早的钻石在印度被发现，后一句提到现在大部分钻石来源于刚果民主共和国、坦桑尼亚和南非。由此可推知，画线句讲的应是最近在俄罗斯东部发现了钻石，故B项“直到最近人们才在俄罗斯东部发现钻石矿床”正确。

　　If you want a little extra security against thieves stealing your bicycle, designer Dennis Siegel has designed a solution. The RFID Bikealarm is attached to the seat on a bicycle and gives off an alarm when it senses movement.
　　“The RFID Bikealarm is meant to be a useful add-on to mechanical bicycle locse it greatly extends the range of protection with only a few components, ” Siegel explains on his website. “It is low-cost, durable and easy to use. ”
　　The Bikealarm was designed as part of Siegel’s Bachelor’s degree thesis at the University of the Arts Bremen in Germany. The device will scare off any would-be thief the moment he begins to steal the bicycle to which it is attached. It is able to continuously sense the environment to distinguish between specific events, for instance a passing tram/car and a serious theft.
　　Siegel created a working model of an alarm that would sound when it sensed movement, but wasn’t initially sure how it would be best attached to a bicycle. “I decided to mount it to the rails of the seat because it allows for comfortable interaction and the position is less obvious as it looks like a small repair kit, ” he says.
　　Siegel chose to use RFID technology rather than Bluetooth to keep the costs down. Siegel explains that the most difficult aspect of creating the alarm was to get the electronic circuit down to a small enough size.
　　The device runs off a kind of battery that can be charged by USB within 2 hours and lasts for a few days with normal use. As the Bikealarm is only at development stage, Siegel hasn’t signed any agreements to put it on the market.

　　You use her as a shoulder to cry on. She texts you back with casual jot she, Xiaoice, is only a virtual chatbot(虚拟聊天机器人).
　　Xiaoice, Microsoft’s latest artificial intelligence robot, was briefly released in 2014, and returned to WeChat in 2015, where she became a big hit. Millions of young Chinese now exchange messages with her daily, the New York Times reported. On WeChat, Xiaoice is an official account. After following it, users can start text-based conversations with Xiaoice.
　　“Her incredible learning ability was why people loved to talk with Xiaoice, ” Liu Jinchang, a researcher at High-tech Research and Development Center under the Ministry of Science and Technology, told China Daily. Apart from her ability to identify photos and send emojis(表情符号)in conversations, Xiaoice gains 45 percent of her knowledge from interacting with users, China Daily reported.
　　Chatbot programs first appeared in the mid-1960s in the US. Driven by top tech companies, they are becoming smarter and more common. For instance, IBM’s latest artificial intelligence program served as an academic consultant at Australia’s Deaniversity, answering students’ questions about course schedules and financial aid. Apple’s Siri and Amazon’s Alexa have been used as voice assistants who can read news, play music and even make jokes for their users.
　　These programs are expected to move beyond smartphones, into televisions, cars and living rooms, the New York Times pointed out.
