	Here's a reminder of the functions we saw in the last section. They should be useful for the exercises!	这里是上一节我们学到的函数的提醒。它们应该对练习有用！
	:command:`sum(expression)` aggregate to return a sum for a set of records	::command:`sum(expression)` 聚合函数，用于计算记录集合的数值总和
	:command:`count(expression)` aggregate to return the size of a set of records	:command:`count(expression)`聚合函数，用于返回记录集的条目总数
	:command:`ST_Contains(geometry A, geometry B)` returns true if geometry A contains geometry B	:command:`ST_Contains(geometry A, geometry B)`如果几何图形 A 包含几何图形 B，则返回 true
	:command:`ST_Crosses(geometry A, geometry B)` returns true if geometry A crosses geometry B	:command:`ST_Crosses(geometry A, geometry B)`如果几何图形A与几何图形B交叉，则返回true
	:command:`ST_Disjoint(geometry A , geometry B)` returns true if the geometries do not "spatially intersect"	:command:`ST_Disjoint(geometry A , geometry B)`如果几何图形不“空间相交”，则返回true
	:command:`ST_Distance(geometry A, geometry B)` returns the minimum distance between geometry A and geometry B	:command:`ST_Distance(geometry A, geometry B)`返回几何图形A和几何图形B之间的最小距离
	:command:`ST_DWithin(geometry A, geometry B, radius)` returns true if geometry A is radius distance or less from geometry B	:command:`ST_DWithin(geometry A, geometry B, radius)`如果几何图形 A 与几何图形 B 的距离为‘radius’或更近，则返回 true
	:command:`ST_Equals(geometry A, geometry B)` returns true if geometry A is the same as geometry B	:command:`ST_Equals(geometry A, geometry B)`如果几何图形 A 与几何图形 B 相同，则返回 true
	:command:`ST_Intersects(geometry A, geometry B)` returns true if geometry A intersects geometry B	:command:`ST_Intersects(geometry A, geometry B)`如果几何图形 A 与几何图形 B 相交，则返回 true
	:command:`ST_Overlaps(geometry A, geometry B)` returns true if geometry A and geometry B share space, but are not completely contained by each other.	:command:`ST_Overlaps(geometry A, geometry B)`如果几何体A和几何体B有公共空间，但不完全由彼此包含，则返回true。
	:command:`ST_Touches(geometry A, geometry B)` returns true if the boundary of geometry A touches geometry B	:command:`ST_Touches(geometry A, geometry B)`如果几何体A的边界接触几何体B，则返回true
	:command:`ST_Within(geometry A, geometry B)` returns true if geometry A is within geometry B	:command:`ST_Within(geometry A, geometry B)`如果几何图形 A 在几何图形 B 内部，则返回 true
	Also remember the tables we have available:	当然！我们有以下表可用：
	``nyc_census_blocks``	``nyc_census_blocks``
	blkid, popn_total, boroname, geom	blkid, popn_total, boroname, geom
	``nyc_streets``	``nyc_streets``
