解析

【分析】
本题为短文填空,需结合短文语境、语法规则及固定搭配,对方框内单词进行适当变形。解题时先通读短文理解大意,再逐个分析每个空的语法成分和语境需求:39空需对应“秒”的对应名词,用复数形式;40空前有than,需用形容词比较级;41空考查固定搭配,需用特定形容词;42空考查begin的用法,需用不定式;43空需用形容词修饰名词。
【解析】
39. 语境为“下载信息仅需几秒,而非________”,minute是可数名词,此处表泛指,用复数形式minutes。
40. 由句中than可知需用形容词比较级,fast的比较级为faster,符合“速度是标准家庭网20倍”的语境。
41. 固定搭配be tired of意为“厌倦”,主语为users(人),用修饰人的形容词tired(tiring修饰物,不符合),故填tired。
42. 固定搭配begin to do sth. 表示“开始做某事”,故将use变为不定式to use。
43. 需用形容词修饰名词services,month的形容词形式为monthly(每月的),符合语境。
【答案】
39.minutes 40.faster 41.tired 42.to use 43.monthly
【知识点】
形容词比较级、固定搭配、词形变换
【点评】
本题考查短文填空中的词汇适当形式,侧重基础语法(比较级、不定式)和固定搭配的运用,需学生结合语境准确变形,是常见的基础题型,难度适中。

We had better walk or ride bikes to school. Third, we must save water. At last, we should neither throw rubbish about nor spit in public. Don't walk on grass or pick flowers.
