Use 离 (lí, from) to describe the distance between two places. Just say 离 between the two locations, and then add 近 (jìn, close) to say close, or 远 (yuǎn, far) to say far.
You can also use 很 (hěn, very) or 太 (tài, very, so, or too) before the adjective.
When you use 太, remember to add 了 (le) after the adjective.
You’ve already learned to use 得 (de) after a verb to describe the action. For example, 你说得很快 (nǐ shuō de hěn kuài) means You speak quickly.
We can also add 得 (děi) before a verb to say need to. Notice that the pronunciation changes!
