The heart has four <em>chambers</em>.
心脏有两房两室。
The Senate started on the right fool. In1986, it limited its franking budget to half the total appropriation for both <em>chambers</em>. That seemed fair because the100 senators represent the same total number of constituents as the435 House members.
参院走出了正确的第一步。1986年把参院的免费邮件预算限制在参众两院该项预算总和的半数。100位参议员与435位众议员的选民人数一样,所以看来这是公平的做法。
