本题对应人教版八年级上册Unit7的语法知识点，考查名词复数、固定搭配、一般将来时、形容词比较级、反身代词、词性转换等内容：
30. 空格前有some修饰，可数名词prediction需要变为复数形式；
31. 考查固定搭配be able to do sth.，意为“能够做某事”，要接不定式结构；
32. 考查固定用法the same，意为“同样的”，是固定搭配；
33. 根据时间状语in the future（在未来），句子要用一般将来时结构will+动词原形；
34. 副词much常用来修饰形容词比较级，此处表示让生活舒适得多；
35. 考查固定短语at the same time，意为“同时”；
36. 考查固定搭配by oneself，意为“独自、自行”，此处指代复数的lights，要使用对应的反身代词；
37. 考查固定结构succeed in doing sth.，意为“成功做某事”，介词in后要接动名词形式；
38. 此处修饰动词短语arrive home，需要使用副词形式；
39. 前后文是因果逻辑关系，前文提到黑客可能通过网络闯入家中而你无法立刻赶回家，因此人们必须小心个人信息，句首单词首字母大写。
