跟读心得日记：
1、You can leave your child with us, safe in the knowledge that they will be extremely well cared for.（C17 Test3 Part2第7句）
safe in the knowledge that用于表示因掌握了某种所说明的情况,做某事无风险或无需担忧。这是一个非常有用的短语组合。类似例句还有：
Parents can focus on their work, safe in the knowledge that their kid have arrived home.
Conservative investors feel safe in the knowledge that the demand for properties is high and income is stable.
2、We are insured to provide care for up to 70 children, although we rarely have this many attending at any one session.（C17 Test3 Part2第8句）
insure 与ensure发音差不多，但是意思和使用环境差别大，insure是投保买保险的意思，而ensure则是确保或保证什么事情，ensure = make sure 比如we must ensure that all the doors are locked.
另外还有个assure，这个是向某人保证，让其放心的意思，She assured me that everything will be fine.
3、I think we generally expect around 50–60 children for the afternoon sessions and about half that number for the breakfast sessions.(C17 Test3 Part2第9句）
half这个词既可以做名词，也可以做形容词和副词，所以当我们说某某东西或数量的一半时，不必要用half of，可以直接用half +sth或half + number。
