Why are firetrucks so loud?

消防车会这么大声，是为了让大家听见它来了，赶快让路。

Xiāofángchē huì zhème dàshēng, shì wèile ràng dàjiā tīngjiàn tā lái le, gǎnkuài rànglù.

消防员有时候要很快赶到火灾现场，或者别的紧急情况那里。警报声是一种特别大声的声音，它像在告诉车子和路上的人：“请让一让，我们要快点过去。” 这样消防车就能更安全、更快地到达需要帮忙的地方。

Xiāofángyuán yǒu shíhou yào hěn kuài gǎn dào huǒzāi xiànchǎng, huòzhě bié de jǐnjí qíngkuàng nàli. Jǐngbàoshēng shì yì zhǒng tèbié dàshēng de shēngyīn, tā xiàng zài gàosu chēzi hé lù shàng de rén: "Qǐng ràng yi ràng, wǒmen yào kuài diǎn guòqù." Zhèyàng xiāofángchē jiù néng gèng ānquán, gèng kuài de dàodá xūyào bāngmáng de dìfang.

下次你听到警报声的时候，你觉得会是什么样的帮助正在路上呢？

Xiàcì nǐ tīngdào jǐngbàoshēng de shíhou, nǐ juéde huì shì shénme yàng de bāngzhù zhèngzài lùshàng ne?

Firetrucks are loud so people can hear them coming and move out of the way.

Firefighters sometimes need to get to a fire or another emergency very fast. The siren is a special loud sound that tells cars and people, "Please make space. We need to hurry." That helps the firetruck get through safely and quickly.

Next time you hear a siren, what kind of help do you think might be on the way?
