zhè tiáo lù hěn wēixiǎn.

条 is a measure word (also called a classifier). In Mandarin, when you use a number or a demonstrative like 这 (this) before many nouns, you usually need a measure word in between.

So:

• 这条路 = this road
• not just 这路 in standard usage

条 is commonly used for things that are long, narrow, or stretched out, such as:

• 一条路 = a road
• 一条河 = a river
• 一条鱼 = a fish
• 一条裤子 = a pair of pants

So in this sentence, 条 is the natural classifier for 路.

Mandarin usually puts the demonstrative first, then the measure word, then the noun:

• 这 + 条 + 路
• this + classifier + road

This is the normal pattern:

• 这本书 = this book
• 那个人 = that person
• 这辆车 = this car

So 这条路 follows a very common and important structure in Chinese.

Not always. This is one of the most common questions learners have.

In English, we say:

• This road is dangerous.

But in Mandarin, when an adjective like 危险 is used as the main predicate, it often sounds more natural to put 很 before it:

• 这条路很危险

Here, 很 does not always need to be translated as very. Very often it just helps the sentence sound natural, almost like a grammatical link.

So depending on context, 这条路很危险 can mean:

• This road is dangerous
• or This road is very dangerous

If you want to clearly emphasize very, you can use stronger words such as:

• 这条路非常危险 = This road is extremely/very dangerous
• 这条路特别危险 = This road is especially dangerous

Because 危险 is an adjective, and in Mandarin, adjectives can act as the predicate directly.

So Chinese says:

• 这条路很危险

not:

• 这条路是很危险 ❌

A simple way to think about it:

• Use 是 mainly to connect noun = noun
  • 他是老师 = He is a teacher.
• Do not usually use 是 before an adjective predicate
  • 她很高 = She is tall.
  • 天气很冷 = The weather is cold.
  • 这条路很危险 = This road is dangerous.

Here, 危险 is functioning as an adjective meaning dangerous.

So in:

• 这条路很危险

it describes the road.

But 危险 can also sometimes act like a noun in other contexts, depending on the sentence. For a beginner, the most useful thing to remember here is:

• in this sentence, 危险 = dangerous
• it is acting like an adjective

In standard Mandarin, with 这 / 那 + noun, you normally use a measure word, so:

• 这条路很危险 ✅

is the expected form.

You may sometimes hear classifier omission in casual speech or certain regional styles, but for a learner, it is much safer and more natural to keep 条.

So the best answer is:

• Use 条 here.

The pinyin is:

• zhè tiáo lù hěn wēixiǎn

The tones are:

• 这 zhè — 4th tone
• 条 tiáo — 2nd tone
• 路 lù — 4th tone
• 很 hěn — 3rd tone
• 危 wēi — 1st tone
• 险 xiǎn — 3rd tone

A few pronunciation notes:

1. 条 tiáo sounds like tyao, not like English tee-ow.
2. x in 险 xiǎn is a Mandarin sound made with the tongue forward; it is not exactly like English sh or s.
3. In connected speech, 很 often does not sound like a full, dramatic third tone. It is usually lighter and smoother than beginners expect.

A natural rhythm is:

• zhè tiáo lù hěn wēixiǎn

Usually it means a real, physical road:

• this road

But depending on context, it can also be understood more broadly as:

• this route
• this path

So if someone is talking about travel, directions, or driving, 这条路很危险 could mean:

• this road is dangerous
• this route is dangerous

The exact interpretation depends on the situation.

You can put 不 before 危险:

• 这条路不危险。 = This road is not dangerous.

Notice that 很 usually disappears in a simple negative sentence:

• 很危险 = dangerous
• 不危险 = not dangerous

You would not normally say:

• 这条路很不危险 ❌

A very common way is to add 吗 at the end:

• 这条路很危险吗？ = Is this road dangerous?

Another natural spoken pattern is the A-not-A form:

• 这条路危险不危险？ = Is this road dangerous or not?

Both are useful, but the 吗 version is usually easier for beginners.

You can use stronger degree words than 很:

• 这条路非常危险。 = This road is very dangerous.
• 这条路特别危险。 = This road is especially dangerous.
• 这条路十分危险。 = This road is extremely dangerous.
• 这条路太危险了。 = This road is too dangerous / really dangerous.

This is useful because, as mentioned earlier, 很危险 often just means dangerous in ordinary Mandarin, not necessarily strongly very dangerous.

Yes.

• 这条路很危险。 = This road is dangerous.
• 那条路很危险。 = That road is dangerous.

So the structure stays the same:

• 这 / 那 + measure word + noun + 很 + adjective

This is a very common pattern that you can reuse with many other nouns and adjectives.
