It's actually rather difficult to say which cities【23】the largest. There are two reasons for this difficulty. First of all, it isn't easy to determine a city's boundaries, that is, where a city ends. Nowadays, nearly all cities have a large【24】area around them. So when we talk about the population of a city, we often mean the population of the whole metropolitan area around the city. That means that it's difficult to determine what the population of a city is because it's difficult to define what a city is.
The second reason that it is difficult to【25】the population of different cities is this: it is almost impossible to get【26】about the population of all cities for the same year. For example, we might get an estimate of New York's population in 1979 and an【27】of Mexico City's population in 1981. So we real ly can't compare the numbers because the information is for【28】different years. And the population of cities changes rather quickly, especially in some cases. For example, the population of Jakarta, Indonesia, may increase by 5% each year, so the population figure will change rather quickly.
So we can say that these are our two【29】for comparing the populations of cities: one, it's difficult to determine the【30】of a city, and two, it is difficult to get accurate information.

Did you ever wonder what occurs inside your body when something funny happens？ What is this thing we have in our brains that makes us say "ha-ha" when someone26abanana？
One way to find out is to watch the brain laugh. That"s what Dartmouth neuroscientist William Kelley did. He and his team had a number of volunteers watch an27of Seinfeld while being monitored by an MRI， a machine that allows researchers to see which parts of the brain are active at any 28 time. They then matched the MRI data with the laugh track to see how the brain changes when it"s 29 something funny. There"s no one "funny center" in the brain——but the findings were pretty.
When subjects were looking at something funny， the two regions in their left hemispheres lit up. From 31 studies these regions are known to be associated with resolving unclear meanings. Is there something in "getting it" that"s 32 the process by which we work with unclear information until we suddenly see the pattern in it？
A couple seconds later two other brain regions became 33， called the insula（岛叶 ） and the amygdala（扁桃腺 ）. The insula is associated with 34， so it seems likely that this is the brain feeling good when it gets the joke——the "ha-ha" response. The amygdala is associated with memory formation. As the researchers35，while you may not be able to remember every plot detail in an episode of a soap opera， you can probably remember the jokes. Humor stays with us， forming a lasting memory.

Dear Mr. Robert,
Although we sent you your goods on time, we have waited nearly two months for you to pay the balance of $ 5000, which is over due. When you ordered the shipment of computers, you requested that we send you the entire order no later than June 1 , and we shipped the goods by air freight on May 25.
As you agreed in our original credit arrangement (赊账协议) , payment was due in 30 days, on June 30. Yet, as it is already August 26, we still have not received your payment. In fact, we have not received any answer to the notice we sent to remind you that the payment was due.
We regret to say that if we cannot receive your payment by September 15 , we will be forced to ask our lawyer to take measures and collect it through legal procedures.
Yours faithfully,
Adam Smith
