2015年,中国科学家屠呦呦因发现治疗疟疾的新疗法荣获诺贝尔医学奖。屠呦呦带领团队经过艰苦卓绝的努力并从《肘后备急方》等中医古典文献中获取灵感。《肘后备急方》的治疟验方:“青蒿一握,以水二升渍,绞去汁,尽服之。”但用传统的“熬汤”的方法无法取得治疟疗效,屠呦呦用低沸点的乙醚成功制取了青蒿提取物,开创了疟疾治疗新方法,全球数亿人因这种“中国神药”而受益。这表明(    )

A:  从《肘后备急方》获取灵感﹣﹣对传统文化批判性继承是文化创新的根基

B:“熬汤”的方法无法取得治疟疗效果﹣﹣对落后文化要自觉加以改造

C:用沸点较低的乙醚提取青蒿提取物﹣﹣科技是推动文化发展的决定因素

D:开创了疟疾治疗新方法﹣﹣社会实践是创新的源泉和动力

阅读下列短文,从每题所给的四个选项(A、B、C和D)中选出最佳选项。

    Is your TV connected to the Internet? What about your chair, or your fridge? Probably they are not. But in the future, most things in your home may be connected, thanks to the so-called "Internet of things".

    The Internet of things may be coming sooner than you think. Earlier this year, Samsung CEO spent a lot of time talking about the Internet things. He said that three years from now, every Samsung product will be part of the Internet of things, no matter whether it's a remote control or a washing machine.

    So, how do household objects that are part of the Internet of things work? Well, think of a common chair. When connected to the Internet, the chair warms up when it knows the user has just walked into the room and is feeling cold.

    An Internet-connected camera could help people feel safer in their homes. It can know people's faces and has an infrared sensor(红外传感器), so even if it's dark it can see when someone passes by and send you a message on your smart-phone to let you know who's there. If the person is someone you don't know, it can tell you that, too.

    But according to MIT Technology Review, whether companies are connecting dog food bowls or safety systems to the Internet, there may be some problems. For example, many early connected-home objects don't have much built-in security, which means they could be hacked(攻击). Moreover, it could be difficult to get these new machines to work together especially when they are made by different companies. To fight this, many companies have joined the Open Interconnect Consortium, which had 45 members by late 2015.

    So, picture this: you enter your home. The temperature changes to make you feel comfortable. Your favorite music starts playing for you. Do you think that this would be a good thing? It may happen sooner than you think.
