Monday morning. Xiaoyu went hiking; Chen Hao slept for two days.
Chen Hao
小雨，周末你去哪儿了？
Xiǎoyǔ, zhōumò nǐ qù nǎr le ?
Xiaoyu, where did you go at the weekend?
Xiaoyu
我跟朋友去爬山了，城西边的那座。你去过吗？
Wǒ gēn péngyou qù páshān le, chéng xībiān de nà zuò. Nǐ qù guò ma ?
Hiking with friends, up the mountain west of the city. Have you ever been?
Chen Hao
去过一次，两年前。山上的风景真好。
Qù guò yī cì, liǎng nián qián. Shān shàng de fēngjǐng zhēn hǎo.
Once, two years ago. The view up there is magnificent.
Xiaoyu
我们早上六点出发，中午就到山顶了。
Wǒmen zǎoshang liù diǎn chūfā, zhōngwǔ jiù dào shāndǐng le.
We set off at six in the morning and were at the top by midday.
Chen Hao
累不累？
Lèi bù lèi ?
Was it tiring?
Xiaoyu
下山的时候腿特别疼。
Xià shān de shíhou tuǐ tèbié téng.
On the way down my legs hurt terribly.
Chen Hao
我周末哪儿也没去，在家睡了两天。
Wǒ zhōumò nǎr yě méi qù, zài jiā shuì le liǎng tiān.
I did not go anywhere at the weekend, I slept for two days at home.
Xiaoyu
下个星期天一起去吧，天气预报说不会下雨。
Xià gè xīngqītiān yīqǐ qù ba, tiānqì yùbào shuō bù huì xià yǔ.
Come next Sunday, the forecast says it will not rain.
Chen Hao
好啊，这次我带相机。
Hǎo a, zhè cì wǒ dài xiàngjī.
Gladly, this time I will bring the camera.
去爬山了 places the outing at a particular moment, this weekend. 去过一次 does not say when: it attests that the thing has happened at least once in a lifetime. The question 你去过吗 therefore expects an answer about experience, and 我去了 would not answer it. The negative separates them better still: 没去 for a fact, 没去过 for a whole life.
Chinese does not say "nowhere" with a special word: it takes the question word, follows it with 也 or 都, and then negates. 哪儿也没去, to go nowhere; 什么都不想吃, to want nothing to eat; 谁也不认识, to know nobody. The same construction without the negative gives the universal: 什么都吃, he eats anything.
座 serves for mountains, bridges, buildings, cities: 一座山, 一座桥, 一座城市. It names what is set on the ground and stays there, which is why it is used neither for a tree (一棵) nor for a road (一条). Getting a measure word wrong does not make the sentence incomprehensible, but it is heard straight away.
