1.使用时不能和小朋友互动(ask question and get feedback)
例文： The speaker rebuts反驳 the reading's argument by pointing out the inadequacy of the web-storybook services' interaction with children, the incompleteness of the data pool, and by undermining the assumption that saving parents' reading time is a benefit.
The speaker begins by stating that merely pronouncing the words and story for the children will not provide adequate learning experiences. Despite the time saved and pronunciation utilities laid out in the reading, the web services can only respond with "correct" or "not correct". The lack of feedback to children's questions will not create an effective learning process.
Then the speaker goes on to argue that the current web-storybook services have a very limited collection of books, thus not being able to save parents the cost of new books as the reading states, because the parents still have to buy many books that the web services do not provide.
Lastly, the speaker challenges the validity有效，正当 of the assumption of saving parents' time to read stories to children. The reading argues that saving the time is a benefit for the parents, but the speaker maintains that the whole point of reading stories is far beyond reading stories alone. In contrast, it is an essential way of communicating and building relationship between parents and children.
