[语篇解读]　本文是一篇应用文。文章主要介绍了四本以女孩为主角的科幻小说。

1．D　[细节理解题。根据The Care and Feeding of a Pet Black Hole部分“Stella goes on a day trip to NASA and brings home a very unusual souvenir－a black hole that acts like a pet！(斯特拉去美国国家航空航天局进行了短途旅行，并带回了一件非常奇特的纪念品——一个像宠物一样行事的黑洞！)”可知，The Care and Feeding of a Pet Black Hole这本书中的Stella从美国国家航空航天局带回了某样东西。]

2．C　[细节理解题。根据Plotting the Stars: Moongarden部分“Myra, the main character, finds a hidden garden filled with dangerous plants.This discovery sets off a chain of events that changes her life forever.(米拉是故事的主角，她发现了一个隐藏的花园，里面长满了危险的植物。这一发现引发了一系列事件，彻底改变了她的生活。)”可知，在Plotting the Stars: Moongarden中，Myra发现了一个隐藏的花园，这改变了她的生活。]

3．B　[推理判断题。根据第一部分“But things don't go as planned.There are lots of problems along the way that threaten to ruin their vacation.(但事情并没有按计划进行。一路上有很多问题可能会毁了他们的假期。)”；第二部分“At first, it seems fun because the black hole can suck up(吸收) anything.But then it sucks up Stella and

her little brother.As Stella tries to get back home, she also has to deal with the sadness she feels since her dad passed away”；第三部分“Hana is trying to win a competition to connect her mind to the web, but she discovers a dangerous plot that puts her loved ones in danger.(哈娜正试图赢得一项连接自己思维与网络的竞赛，但她却发现了一个危险的阴谋，这阴谋将她的亲人置于危险之中。)”以及最后一部分“This discovery sets off a chain of events that changes her life forever.(这一发现引发了一系列事件，彻底改变了她的生活。)”可知，这些书中的主角有一个共同点：她们都面临着挑战。]

 

 

 

Have you ever lost something in a hard­to­reach space，like behind a couch or a cupboard? Wouldn't it be nice to just be able to squeeze in and out? New innovations in the field of robotics will soon be able to make this nice idea into a reality.

In a study published on Jan. 25 in the science journal Matter, engineers from The Chinese University of Hong Kong and Carnegie Mellon University in the US have developed small robots that can quickly change back and forth from liquid to solid states.

According  to the website Mashable, the scientists were inspired by sea cucumbers. They are able to change the stiffness(僵硬度) of their body or reduce the potential for physical damage. The robots in the study were made from gallium(镓), a soft metal with a low melting point of 30℃. The scientists then used changes in the magnetic field to control the magnetic particles inside the gallium material to provide heat. This heat then allowed the robots to change between solid and liquid states as well as to move around.

As the website Tech Xplore pointed out，other similar materials require external heat sources such as heat guns and electrical currents to induce a change of states; but now, the robots can use a heat source inside itself to change states independently. During the robots' experimental trials，the scientists conducted a number of tests. These tests included having the robots melt into liquid and re­form to escape a prison­like cage. It can remove a foreign object from and deliver medicinal drugs to a model stomach. The robot is also able to build and repair hard­to­reach circuits. The robots' ability to switch between states of matter allows for a number of possible uses and advancements in different fields, such as the biomedical and circuit assembly(组装) industries.

 Still，in the words of senior author Carmel Majidi at Carnegie Mellon University, for now
