下一阶段，具体运算阶段，七到十二岁，儿童可以解决守恒问题，但儿童的抽象推理能力仍然有限。

The next phase, concrete operations, from seven to twelve, you can solve the conservation problem, but still you're limited to the extent you're capable of abstract reasoning.

第一，通过将其他字符串添加在一起，可以创建新的字符串，具体方法可以使用+运算符，或者干脆使用适当的引号将字符串连在一起。

First, you can create a new string by adding other strings together, either using the + operator or by just sticking strings together using the appropriate quotes.

对成员2007执行的查询将返回来自数据集[cube B]的结果，对成员2008执行的查询将返回来自[cubea]和[cube B]的结果(具体结果取决于合并运算符)。

A query against 2007 returns data from its parent cube [CubeB], and a query against the merged member 2008 returns the results from both [CubeA] and [CubeB] according to the merge operator.

We'll, later in the term when we get to more detailed numerical things, look at what's wrong.

这个学期的晚些时候我们,会做一些更具体的数值运算。
