Learn Hardcore Chinese: tā yuē wǒ míngtiān zài túshūguǎn jiànmiàn, zhǐyào bù lěng wǒ jiù qí zìxíngchē qù. - She asked me to meet at the library tomorrow; as long as it isn’t cold, I’ll bike there.

只要…就… means “as long as…, then…”. It states a sufficient condition: whenever the condition holds, the result follows. Pattern: 只要 + condition，(subject) 就 + result. In your sentence: 只要不冷，我就骑自行车去. Using 就 is standard; dropping it is possible but less natural.

Why is it 不冷 and not 没冷?

不 negates states/adjectives or habitual/future actions; 没(有) negates past or completed actions/existence. 冷 is an adjective, so use 不冷. Tone tip: 不 changes to bú before a 4th tone, but stays bù before lěng (3rd tone).

Why use 见面 instead of 见?

见 is “to see/meet” and can take a direct object: 见她 “see her.”
见面 is “to meet (each other),” inherently mutual and intransitive. It cannot take a direct object. Use 跟/和 + person + 见面 if you name the other person.

Do I need 跟/和 with 见面 here?

Not in this sentence, because 她约我…见面 already makes the participants clear. If you restate the partner, say 明天在图书馆跟她见面 or 我们明天在图书馆见面.

Is the time/place order right? Could I say 在图书馆明天见面?

Yes, it’s right. Default order is Subject + Time + Place + Verb: 我们明天在图书馆见面. Saying 在图书馆明天见面 is awkward.

What does the final 去 refer to? “Go where?”

The destination (the library) is understood from context. Chinese often omits obvious information. To be explicit: 我就骑自行车去图书馆.

Why 在图书馆见面 instead of 到图书馆见面?

在 + place marks where the action happens. 到 + place expresses “arrive/go to” and usually pairs with a motion verb: 到图书馆去见面 works, but 在图书馆见面 is simpler and most common.

Why use 去, not 来?

Use 来 for movement toward the speaker’s current location; 去 for movement away from it. The library isn’t the speaker’s current location, so 去 fits.

Can I drop the second 我 in 我就骑自行车去?

Yes. Subjects are often omitted when clear: 只要不冷，就骑自行车去 is fine in context.

What exactly does 就 add here?

It links condition to result (“then/so”) and makes the consequence feel prompt/guaranteed. Without 就, it’s grammatical but less idiomatic after 只要.

Should there be a comma after 只要不冷?

Preferred punctuation is 只要不冷，我就骑自行车去. Your sentence’s comma after 见面 is fine, but most writers also add the comma between condition and result.

Is 见面 a separable verb? How do I add aspect or measure words?

Yes, it’s a verb–object compound (离合词):

Aspect: 见了面, 见过面
Quantification: 见一次面, 见个面 It still can’t take a direct object: say 跟她见了面, not 见面她.

Do I need 了 after 约? What’s the difference between 约 and 邀请/约会?

了 after 约 (e.g., 约了我) emphasizes the inviting act as completed; without 了 it can read as a present plan/arrangement. Both are acceptable here.
约 = arrange/ask to meet (neutral, informal). 邀请 = invite (more formal). 约会 = go on a (romantic) date.

Could I use 如果 instead of 只要?

Yes, but nuance changes. 如果…就… = “if… then…,” neutral. 只要…就… = “so long as… then…,” highlighting that the single condition is enough. Your sentence promises biking whenever it’s not cold.

Is 骑车 okay, or must I say 骑自行车?

骑车 is natural and common shorthand. All of these work: 我就骑车去, 我就骑自行车去.

Do I need 会 to show future: 我就会骑自行车去?

Not required. Chinese often uses present form for future context. 会 adds a predictive tone (“will/likely will”), slightly softer.

Could I say 她跟我约明天在图书馆见面 instead of 她约我…?

Yes. 她跟我约… highlights mutual arrangement; 她约我… highlights her initiating the invite. Both are natural here.
