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。
