上述实验证实了多项选择注释可以促进词汇附带习得，但它也有难以克服的局限

The above experiments confirmed that multiple choice annotation can promote incidental vocabulary acquisition, but it also has limitations that are difficult to overcome. For example, there is no guarantee that the learner can make the correct choice or establish the correct form and meaning connection according to the context when the learner chooses the meaning of the target word for the first time. Once the learner chooses the wrong annotation meaning, it will cause a series of subsequent reading comprehension misunderstandings. This result goes against the original intention of establishing multiple choice annotations. In order to avoid this problem as much as possible, the later experiments of multiple-choice annotations gradually shifted from a comparison with single-item annotations to task-based research that increases the amount of input.

上述实验证实了多项选择注释可以促进词汇附带习得，但它也有难以克服的局限性。例如无法保证学习者在第一次目标词词义选择时就能根据上下文做出正确的选择或建立起正确的形义联系。而一旦学习者选择错误的注释意思，就会引起后续一系列的阅读理解误区。这样的结果违背了设立多项选择注释的初衷。为了尽量避免该问题，后期多项选择注释的实验逐渐从与单项注释的对比走向了增加投入量的任务型的研究。

These experiments confirm that multiple choice annotation can promote incidental vocabulary acquisition, but it also has some limitations that are hard to overcome. For example, there is no guarantee that learners can make the right choice or establish the correct relationship between form and meaning according to the context when they first choose the meaning of the target word. Once learners choose the wrong annotation meaning, it will lead to a series of misunderstanding in reading comprehension. This result violates the original intention of setting up multiple choice annotation. In order to avoid this problem, the experiment of multiple choice annotation gradually changed from the comparison with single annotation to task-based research with increasing input.<BR>
