expect接不定式作宾语表示期待某事的发生
“expect”是一个常用的动词，意为“期待”、“期望”或“预料”。当“expect”接不定式作宾语时，它表示期待某人做某事或期待某事的发生。以下是关于“expect”接不定式作宾语的用法辨析：
1. expect + to-不定式：这是“expect”最常见的用法之一，表示期待或期望做某事。不定式“to do”作为宾语，描述了期待的具体内容。例如：
* We expect to arrive in Paris by the end of the week. 我们期待这周末到达巴黎。
* They expect to complete the project by next month. 他们期望下个月完成这个项目。
2. expect + 宾语 + to do：在这种结构中，“expect”后面先接一个宾语，再接一个不定式作宾语补足语，表示期望某人做某事。例如：
* We expect you to arrive on time. 我们期望你准时到达。
* They expect him to perform well in the exam. 他们期望他在考试中表现出色。
3. expect + that-从句：虽然“expect”通常接不定式作宾语，但它也可以接宾语从句，表示对某事的期望或预计。在这种情况下，从句通常使用将来时态。例如：
* We expect that the meeting will be postponed. 我们期望会议会推迟。
* They expect that he will recover soon. 他们期望他很快会康复。
需要注意的是，“expect”后面接不定式时，不定式通常不带“to”作宾语补足语，即不能说“expect sb. to do sth.”，而应该说“expect + 宾语 + to do”或者“expect + to-不定式”。
总结来说，“expect”接不定式作宾语时，表示期待或期望做某事或某事的发生。它可以直接接不定式“to do”作为宾语，也可以接宾语后再接不定式作宾语补足语，或者接宾语从句表达期望的内容。
