Notes:

A more direct translation of this phrase would be "Is your health good?"

This is a polite question that is asked when we assume that the other person is in fact well. If we know that the person has recently been sick, or looks sick at the moment, there are other questions we can ask to show a greater degree of awareness or concern. We will study these in later units.

Notes:

A little more about 也 yě:

 也 yě is an adverb that introduces additional information. It does this in two ways, one by introducing additional information about a subject, and the second by stating a similarity between two different subjects. So far, we have only seen the second type, but as new verbs get introduced in later lessons we will see the first type more and more.

Notes:

马特 Mǎtè shows his respect for 张老师 Zhāng lǎoshī by using the respectful form of the pronoun you, 您 nín, as well as by using the teacher's title, 老师 lǎoshī while speaking to her.

你呢？ Nǐ ne? can be translated as And you? Follow up questions with 呢 ne are used to ask the same question as the preceding question, but about another subject or object.

Notes:

再见 zàijiàn is the most common way to say goodbye, it literally means "see you again". There are other ways to say goodbye used when speakers have a more or less particular time they expect to see each other again. 明天见  Míngtiān jiàn, meaning See you tomorrow, is one of these expressions.
