• 指示限定词，用在单数或不可数名词前，指在空间、时间或语境中距离说话者较远的人或事物。

A word used before a singular noun or uncountable noun to point to something that is distant in space, time, or discourse from the speaker or writer. It functions as a demonstrative determiner, helping to identify or specify which particular item is being referred to when there is more than one possibility.

1. Demonstrative determiner indicating distanceA1formal

   Used to refer to a singular noun or uncountable noun that is physically farther away from the speaker, or conceptually more distant in time or previous mention. It contrasts with 'this' which indicates nearer items and helps the listener understand exactly which one among several is meant.

   • Can you hand me that book on the top shelf?

2. Use with singular countable nouns for specific referenceA2formal

   Precedes a singular countable noun to make it clear which particular item is being discussed, especially when the item is not close to the speaker or when contrasting with something nearer. It adds precision to identification without needing additional descriptive words.

3. Referring to abstract or previously mentioned ideasB1formal

• 代词，用来代替名词或名词词组，指代较远的人或事物，或引出关于已提到对象的补充信息；也可引导定语从句或表示“那个、那种、那样”。

A word used in place of a noun or noun phrase to refer to something already mentioned, known from context, or being pointed out. It functions both as a demonstrative pronoun indicating distance (farther away) and as a relative pronoun introducing additional information about a previously mentioned noun. This helps avoid repetition and connects ideas smoothly in sentences.

1. Demonstrative pronoun (indicating something farther away)A1formal

   Used to refer to a specific thing, person, idea, or situation that is distant in space, time, or context from the speaker, replacing a noun to avoid repetition while pointing it out.

   • We tried many restaurants last month. That was the most expensive one.

2. Relative pronoun (introducing a relative clause)B1formal

   Used to connect a clause that provides more information about a noun mentioned earlier, often referring to things or ideas rather than people, and functioning as the subject or object within that clause.
