• IoT encourages the communication between devices.
• They are better to operate thanks to the connection of more technical information.
• IoT helps to increase efficiency (效率) and save more money by using less strength and time.
• Making daily life tasks smart keeps track of devices well.
• Their good qualities make a better life.
Though there are several advantages, there are certain disadvantages too.
• It may become highly difficult to understand.

解析
【分析】本题为英语阅读理解题，分为判断正误和问答两类题型。解题时需先通读全文，明确IoT设备的优缺点相关内容；针对判断正误题，需将题目表述与原文对应细节逐一比对，判断是否符合；针对问答题，需定位原文对应问题的相关语句，提取关键信息作答，注意表述要与原文一致。
【解析】3-1 (1)原文仅列举IoT设备的优缺点，未提及优点数量多于缺点，故题目表述错误，填F；(2)原文明确提到“IoT encourages the communication between devices”，故题目表述正确，填T；(3)原文指出“Their good qualities make a better life”，并非“making daily life tasks smart”直接导致，故题目表述错误，填F；(4)原文提到“IoT devices may become highly difficult to understand”，对应题目“very hard to use”，表述正确，填T；(5)原文提到“there will be reduction in job positions”，并非增加岗位，故题目表述错误，填F。
3-2 (1)定位原文优点第二条，提取“Thanks to the connection of more technical information”作答；(2)定位原文优点第三条，提取“By using less/reducing strength and time”作答；(3)定位原文缺点第二条，可知IoT设备无国际标准，故答案为“No, they aren’t. Because they may not have an international standard”；(4)定位原文缺点第三条，提取“They may reduce job positions”作答；(5)定位原文缺点最后一条，可知IoT设备可能控制生活，故答案为“No, it doesn’t. Because our lives may be out of control if we are controlled by IoT devices”。
【答案】3-1 (1)F (2)T (3)F (4)T (5)F
3-2 (1)Thanks to the connection of more technical information.
(2)By using less/reducing strength and time.
(3)No, they aren’t. Because they may not have an international standard.
