Ⅰ.根据提示填空
Owning a smart phone may not be as smart as you think.They may let you surf the Internet, listen to music and ?snap_photos (抓拍) wherever you are, but they also turn you into a workaholic, it seems.
A study suggests that, by giving you access to emails at all times, the ?smart_phone (智能手机) adds as much as two hours to your working day.Researchers found that Britons work an ?additional (addition) 460 hours a year on average as
they are able to respond to ?_emails (email) on their mobiles.The study shows the average UK working day is between 9 and 10 hours, but a further 2 hours is spent responding to or ?sending (send) work emails, or making work calls.
Almost one in ten admits spending up to three hours outside their normal working day ?checking (check) work emails.Some workers confess they are on call almost 24 hours a day.Nearly two-thirds say they often check work emails just before they go to bed and as soon as they wake up, while over a third have replied to one in the middle of the night.The average time for first checking emails is between 6 a．m. and 7 a．m., with more than a third checking their first email in the period, and a quarter checking them between 11 p．m.and midnight.
Ghadi Hobeika，marketing director of Pixmania，said：“The ability to ?access_millions of_apps (访问数以百万计的应用程序) has made smart phone ?invaluable (valuable) for many people. However, there are disadvantages.Many companies expect their employees to be on call 24 hours a day, seven days a week, and smart phones mean that people cannot ?get_away_from (摆脱) work.The more 10work_capacity constantly in contact we become, the more is expected of us in a ○(工作能力)．”
Ⅱ.片段选词填空
technology， adventure， safety， be cautious about， pick up， come up with， pass through， a hitchhiking robot， GPS tracker， small talk Although most hitchhikers (搭便车的人) are people, passers-by tend to ignore them because they ?are_cautious_about giving rides to strangers. But what will they do if they come across ?a_hitchhiking_robot? Will they take it to its destination or will they just leave the helpless machine by the wayside?
That is the answer Canadian professors, David Harris Smith and Frauke Zeller, who study the relationship between humans and ?technology,_are seeking for after they ?came_up_with the idea of building a hitchhiking robot.
HitchBOT is built with cheap household items. Thanks to a PC tablet, ?GPS_tracker and camera, hitchBOT not only can send its thoughts and pictures to the general public, but also can answer general questions and keep drivers entertained with ?small_talks. The smart robot is even able to quote interesting facts about the areas it has ?passed_through.
Not surprisingly, many people are doubtful about hitchBOT's ability. Most people think the cute robot will be damaged by someone. Actually, they are all wrong. The
robot hitchhiked all the way from Halifax, Nova Scotia, to Victoria, British Columbia, a distance of 3,700 miles. It was first ?picked_up on July 27th by an elderly couple. It not only reached its destination on August 21st, but also had some amazing ?adventures_along the way.

A
(2019·安庆模拟)The United Arab Emirates (UAE) is mostly a desert. However, this has not stopped the country from creating great building projects. On September 26, UAE officials announced another ambitious project — Mars Science City. Expansive deserts and miles of coastline provide plenty of options for safe rocket launches (发射). And its position on the Earth makes it especially appealing as the spin of the Earth provides an extra push, meaning less fuel is needed to get payloads into orbit. All these seem to make it possible.
The Mars City Project, designed by Bjarke Ingels Group, or BIG, will provide a realistic model to simulate (模仿) living on the surface of Mars, the red planet. It is part of the UAE's Mars 2117 Project to lead the global race to land humans on Mars and be the first to build a settlement there. Sheikh Mohammed bin Rashid, Prime Minister and ruler of Dubai, says, “The UAE seeks international support to develop technologies that benefit humans, and lay the foundation of a better future for more generations to come.”
Built outside Dubai, the 1.9 million square feet city is expected to cost $135 million. It will consist of several dome-shaped laboratories, similar to the ones imagined for the first Mars settlers. Scientists from around the world will be invited to conduct research to come up with methods to create food, water and energy, using techniques which can be copied onto the red planet. The living spaces, where the researchers can live for up to a year, will simulate the planet's conditions as much as possible.
The research city will also include a museum featuring famous space achievements to help educate and inspire children to undertake space exploration and discovery. To discover whether the construction method works on Mars, the museum's walls will
