1.听写包答案：

Good question! Abell’s definition of a cluster is this:

First, there have to be more than 50 galaxies within a specific amount of space.
He said basically that clusters have radius of roughly 2 megaparsecs.
And it was just an assumption that all clusters would be about the same size.
It’s remarkable that it proved to be correct. And this standard cluster radius is known today as “the Abell Radius”.
And second, those 50 plus galaxies have to be a certain brightness.
Of course it was a rough estimate, but looking at galaxies’ brightness was a good way to distinguish between clusters that were nearby and those (that) were more distant.
好问题！Abell对星团的定义是：
首先，在特定太空区域内必须有50个以上的星系。
他说基本上星团的半径大约有2个百万秒差距。
而且认为所有的星团规模都一样只是一个假设。
值得一提的是，这被证明了是正确的。现在标准的星团半径被命名为“Abell半径”。
第二，那50多个星系必须有一定亮度。
当然这只是一个粗略的估算，但是看星系的亮度是区分附近的和位置较远的星团的一个好办法。

从某种意义上说,他的记忆力如此之差以至于他对某个曰期或某行诗句的记忆从不会超过几天。

3.写作包答案：

Known as China’s national opera, Peking Opera originated in the late 18th century from the basis of some local operas in Anhui and Hubei Provinces. Peking Opera is the most influential and representative of all operas in China. It has won great popularity not only in China but also throughout the world. Peking Opera is a harmonious combination of many art forms. It is a synthesis of traditional music, dancing, poetry, acrobatics and martial arts. It is famous for its exquisite costumes, beautiful make-up or painted face, and established performing conventions and rules. Each of patterns and brilliant colors on the painted face has a symbolic meaning: red suggests loyalty; blue suggests cruelty; black suggests honesty.
