262. The scientists checked the data for all possible natural influences such as the lunar cycle as well as random variations and found neither to be at play.

译文

科学家检查了所有自然界可能影响的信息，例如月球周期，以及随机变异，却发现两者都没有产生影响。

点睛

本句的主干是scientists checked data and found neither。for all possible natural influences为data的后置定语；such as...为natural influences的补语，其中as well as起到了并列连接作用；to be at play为neither的宾语补足语。

such as的意思是“例如，诸如”，用于举例说明。如：

The town is still reliant on traditional industries such as farming and mining. 该镇仍然依赖于务农和采矿之类的传统产业。

as well as的意思是“也，又，还”。如：

They sell books as well as magazines. 他们既卖书也卖杂志。

at play此处的意思是“起作用”，还可指“在玩耍”。如：

I can hear the happy laughter of children at play. 我能听到孩子们玩耍时欢快的笑声。

考点归纳

such与as的常见组合及用法如下：

as such意为“从字面意义来看，严格说来”。如：

My new job is not a promotion as such. 我的新职务算不上真正的晋升。

such as还可指“像……这样，诸如……之类”。如：

Opportunities such as this did not come every day. 这样的机会不是每天都有的。

such...as意为“……的那些”。如：

Such food as they gave you was warm and nutritious. 他们给你的食物是热的，而且很有营养。
