【答】As scheduled 是As is scheduled 的省略说法。

网友提供了两种可能，现在，作出正误判断：

As scheduled, we will hold a sports meeting. （正）

1. As it is scheduled, we will hold a sports meeting. （误）

2. As is scheduled, we will hold a sports meeting. （正）

又如：

1. The project will go forward as planned. 该工程将按照计划进行。

等于：The project will go forward as is planned.

2. Everything happened as expected. 一切都像预料的那样发生了。

等于：Everything happened as was expected.

▲ 英语在朝着表达简洁的方向发展，as 的这种用法其实是一种省略现象。as之后实际省略了is。在As scheduled, we will hold a sports meeting. 整个句子中，As 在表意上，as指代下文整个主句的内容；在结构上，as又是表示比较的“连词”，身兼两职，as本身又在比较从句中作主语。传统语法称之为“as引导的非限制性定语从句”，新的语法观点称之为“as引导的比较状语从句”。

用于此句式的这类动词，一般是表示“计划，想象，预料，叙述，描述，提及，说及，显示，指出”之类的动词，多用于议论文体。除了as scheduled以外，常见的有：

as expected 正如预料的那样

as imagined 正如想象的那样

as arranged 正如计划的那样

as seen from above 正如从上述看的那样

as told before 正如前述

as shown above 正如上面显示的那样

as said 正如说过的（那样）

as mentioned 正如提到的（那样）

as described 正如描述的（那样）

as discussed 正如讨论过的（那样）

as noted 正如叙述到的（那样）

as stated 正如说指出的（那样）

as announced 正如宣布的（那样）

as pointed out 正如已经指出的（那样）

as indicated 如前所示（那样）

as hinted 正如已经暗示的（那样）

as told 正如已经告知的（那样）

as already shown 如已显示（那样）

as emphasized 正如已经强调的（那样）

as observed 正如已观察到的（那样）

as explained 正如已经解释过的（那样）

as suggested 正如已经提出的（那样）
