No. It’s not necessary (5) . Notes:
1. “shall”和“will”构成一般将来时用的助动词，shall用于第一人称will用于第二、三人称，疑问式是将助动词放置句首，但是在“What shall I do?” “Shall I wash them?”等句中，shall不表将来，而是征求对方意见。 “我干什么呢？”“需要我洗土豆吗？”。
2. 然后呢？
3. 去皮以后呢？
4. “be going to ”表示打算，准备做的事或即将发生或肯定要发生的事。“我们打算用土豆做汤吗？”
5.这是一句省略回答，全句应该是It is not necessary for you to dice the potatoes.这里的“it”为引词作形式主语，真实主语是后面的动词不定式，“to dice the potatoes”。 |
