Dialogues /monologues:

　　1、I would have thought they'd be very useful for children without brothers and sisters.

　　would/should have +过去分词，表示“应该做某事”，而实际没有。

　　本句可以翻译为：我应该想到它们对独生子女是很有用的。

　　2、The reality is that people learn subjects such as languages and mathematics at different speeds.

　　Speed：【俚语】在这里应翻译为： 嗜好，个性：适合某人的兴趣、技能或性格的东西：

　　E.G. Living in a large city is not my speed.

　　住在大城市里不是我所喜欢的

　　1、 My parents recognized that the best learning is learning-by-doing, and they facilitated a lot of interesting experiences for me, whether it was driving me across town, paying for courses and lessons, or just including me in their lives.

　　我的父母认识到，最好的学习方法是边干边学。为此，他们让我体会了许多有趣的经历：或者开车带我在镇里转转，或者花钱让我让各种班，或者干脆将我直接纳入他们的生活。

　　本句解析：My parents recognized that the best learning is learning-by-doing, and they facilitated a lot of interesting experiences for me, (前半部分是具有递进意义的两个并列分句)whether it was driving me across town, paying for courses and lessons, or just including me in their lives. (后半部分是样态状语从句，其中由三个现在分词短语作表语)。

　　2、 interacting with a large group of people my own age was one of the joys I derived from school.

　　Derive sth from sth.

　　<1> 得到，获得。如：

　　She derived no benefit from the course of drugs. 用药疗程后她并无好转。

　　<2>对某事物穷本穷源。如：

　　We can derive the word ‘derelict’ from the Latin ‘derelictus’

　　derelict 一词的起源可追溯到拉丁词 derelictus。
