The interjection 喂 [wèi] can be used to get someone's attention, but can be considered a bit rude. More often 喂 [wéi] as a second tone is used as a greeting when answering the telephone.

啊 [à] is an interjection used to express surprise. It is very much like the English interjection with the same pronunciation "Ah".

The following are a few additional interjections:

The conjunction 和 [hé] is used to join nouns, pronouns, and nominal expressions. Unlike the English "and" it is never used to connect verbs, adverbs, clauses, or sentences.

Note that when 和 is used to join nouns in the subject phrase 都 is often used before the predicate.

The conjunction 也 [yě] is used to join clauses and predicate constructions, but is never used to join nouns alone.

We learn a new way to ask a question in this lesson. As an alternate to using a question word, a common way to ask a question is the choice question. In this type of question the questioner provides a yes or no choice in the form of verb 不 verb.

For transitive verbs the object is placed after the affirmative-negative verb. Like in other question forms the structure of the sentence does not change.

To reply in the affirmative use the verb. Negative replies use the 不 verb option.

A few issues to be aware of when using the affirmative-negative question.

• Don't use with adverbs.
• Grammatically accurate choice questions with multi-syllable verbs will use the complete verb 認識不認識 介紹不介紹.
• The 不 has a neutral tone 是不是[shì bu shì], 對不對[duì bu duì].

When two or more verbs or verbal expressions are used in the same sentence the function of the verb construction dictates the order in which it occurs in the sentence. In this chapter we deal with verb expressions indicating place or location, and constructs indicating purpose. In these type of sentences the place expression always comes before the purpose expression. Place or location expressions use verbs such as 在, 來, and 去.

The negative expression is almost always used in the first verb phrase.
