This exercise machine provides further analysis exercises. Clicking on the button below will generate a sentence to be analyzed, and clicking on the sentence will display an analysis of it step by step, with the next step analyzing the component you have clicked on. If you click on a component when no further analysis is possible, it will be abbreviated. When the final unanalyzed component is abbreviated, the analysis will be displayed in the symbolic and English notation. You can back up to a previous step in the analysis by clicking on it; this will not change the final analysis but it will enable you to display the analysis of components in the different order.

Exercises can be generated quickly and their quality will vary widely, so you should be ready to ignore a suggested exercise and request another you like better. Some problems will be obvious—for example, the machine will sometimes generate very short or very long sentences—but others may be less obvious. In particular, a sentence may be ambiguous and, in such cases, the machine will not always have the most natural analysis in mind. (And it is stubborn: once it has an analysis in mind, there is nothing you can do to convince it to consider a different one.)

The menu just to the right of the exercise button will enable you to the limit the range of examples for certain chapters (and such limits may already have been imposed by the source of the link you followed to the machine). And the button at the far right will hide or show these instructions.
