• Wh- questions usually include the verbs be, have, do, or any of the helping verbs. • To ask for facts, use the question words what, which, who, whom, how, when, where.
Sentence
• Imperatives are a very direct way of telling people to do something. Using do or please before an imperative is more polite.
• 祈使句是告诉人们做某事的一种非常直接的方式。在祈使句之前使用do或please更有礼貌。 • Do sit down. • Do check these figures again. • Please help yourselves to some food. • Please don’t change anything on • my computer.
