英语句子解析The farmers avidly took to pesticides as a sure measure to boost crop yield.为什么took后面加了一个to.so integral have these time-based technologies become to day-to-day existence.为什么become后面加了一个to.这两句话都选自Cambridge IELTS 8

农民到贪婪的技术带到农药作为确定措施以提高作物产量，所以积分有这些基于时间成为日常 existenceThe。我只能帮助你这些了。

took to : 开始(喜爱；养成；走向；容易学会)
The farmers avidly took to pesticides as a sure measure to boost crop yield
农民们贪婪地把杀虫剂来提高作物产量的一个确定的措施
become to : 成为
so integral have these time-based technologies become to day-to-day exist...
所以这些时间积分技术成为日常生活

因为pesticides是行为动词，前面加to

原句应该是：
The farmers avidly took to pesticides as a sure measure to boost crop yield so integral （that they）have these time-based technologies become to day-to-day existence
took to 原形take to 开始从事
have 使 我觉得become 后面的to接become的宾语（个人感觉：强调的方向由、、、变成、、、）
我感觉可以这么意译：
农民们如此热衷于将使用杀虫剂作为提高粮食产量可靠的办法，以至于将这些需要依赖时间起作用的技术变成了每天的必需品。

take to 是固定搭配,意思是“开始经常做某事”（to start doing something often）
另例：
She was so depressed she took to drink.
（她（那时）很压抑,然后开始酗酒.）
become 后的to 不是接在become之后,而是接在integral之后的,这个短语是become integral to ...（逐渐融入到……）.整个句子因为so引起了倒装（助动词have 位于主语之前）,所以读到become时需要停顿.
另例：
Bars and cafés are integral to the social life of the city.
（酒吧和小饭馆融入到这座城市的社会生活中.）
