Lesson 2: Complex Comparisons
Express precise numerical and degree-based comparisons using A是B的N倍, A比B+V得多, and 差不多 at B1 level.
Overview
Basic comparison with 比 (A比B + adjective) is an A2 skill. At B1 you need to express how much bigger, how many times more, and approximate equivalence. The patterns 是...的N倍, 比...V得多, and 差不多 allow you to make quantified and graduated comparisons that appear constantly in academic writing, news, and everyday persuasion. The tricky part is controlling word order: Chinese comparison structures place the degree word after the verb, not before it as in English.
Learning Objectives
- Construct multiplying comparisons with 是...的N倍.
- Use 比 + 得多/得少 to express significant degree differences.
- Apply 差不多 and 相差 to express approximate equality and measurable gap.
- Avoid common word-order errors when attaching degree complements.

Grammar Focus
Pattern 1: A 是 B 的 N 倍
Structure: A + 是 + B + 的 + [number] + 倍
Use this to say A is N times (as much as) B. Note that 是...的N倍 means exactly N times as large, not N times more. So 是两倍 means "twice as much," not "twice more."
| Chinese | Pinyin | English |
|---|---|---|
| 中国的人口是加拿大的三十多倍。 | Zhōngguó de rénkǒu shì Jiānádà de sānshí duō bèi. | China's population is more than 30 times that of Canada. |
| 这个项目的预算是上次的两倍。 | Zhège xiàngmù de yùsuàn shì shàng cì de liǎng bèi. | This project's budget is twice that of last time. |
| 他的薪水是我的三倍。 | Tā de xīnshuǐ shì wǒ de sān bèi. | His salary is three times mine. |
Common mistake: Do not say 是B多N倍 to mean "N times more." This is a frequent interference from English "three times more." In Chinese, 是...的三倍 means three times as much total.
Pattern 2: A 比 B + Verb + 得多 / 多了
Structure: A + 比 + B + [verb/adj] + 得多 OR A + 比 + B + [verb/adj] + 多了
This expresses a significant difference: "much more/less than." 得多 and 多了 are interchangeable here, though 多了 sounds slightly more colloquial.
| Chinese | Pinyin | English |
|---|---|---|
| 今年的收入比去年多得多。 | Jīnnián de shōurù bǐ qùnián duō de duō. | This year's income is much more than last year's. |
| 这条路比那条路短多了。 | Zhè tiáo lù bǐ nà tiáo lù duǎn duō le. | This road is much shorter than that one. |
| 她的中文比我好得多。 | Tā de Zhōngwén bǐ wǒ hǎo de duō. | Her Chinese is much better than mine. |
Common mistake: Avoid inserting 很 or 非常 inside the 比 structure. 比我很好 is wrong. All degree expression goes after the adjective: 比我好得多.
Pattern 3: 差不多 and 相差
Structure A: A + 和/跟 + B + 差不多 (A and B are about the same) Structure B: A + 跟 + B + 相差 + [amount/很大/不多] (A and B differ by...)
| Chinese | Pinyin | English |
|---|---|---|
| 这两款手机的价格差不多。 | Zhè liǎng kuǎn shǒujī de jiàgé chàbuduō. | The prices of these two phones are about the same. |
| 他们两个人的水平相差不多。 | Tāmen liǎng gè rén de shuǐpíng xiāngchā bù duō. | The two of them differ little in skill level. |
| 他们的年龄相差将近十岁。 | Tāmen de niánlíng xiāngchā jiāngjìn shí suì. | Their ages differ by nearly ten years. |
Contrast: 差不多 can also mean "approximately" as a standalone adverb (差不多三点钟 = around three o'clock), so context determines whether it expresses approximate equality or approximate quantity.
Dialogue
Context: Two friends comparing job offers they received.
A: 你最后决定接受哪家公司的offer了？
Nǐ zuìhòu juédìng jiēshòu nǎ jiā gōngsī de offer le?
Which company's offer did you end up accepting?
B: 我选了那家初创公司，虽然薪水和大公司差不多，但股权更好。
Wǒ xuǎn le nà jiā chūchuàng gōngsī, suīrán xīnshuǐ hé dà gōngsī chàbuduō, dàn gǔquán gèng hǎo.
I chose the startup. The salary is about the same as the big company, but the equity is better.
A: 真的吗？我以为初创公司工资一般比大公司低得多。
Zhēn de ma? Wǒ yǐwéi chūchuàng gōngsī gōngzī yībān bǐ dà gōngsī dī de duō.
Really? I thought startup salaries are usually much lower than big companies.
B: 以前是这样，但现在竞争激烈，差距没那么大了。
Yǐqián shì zhèyàng, dàn xiànzài jìngzhēng jīliè, chājù méi nàme dà le.
That used to be the case, but now competition is fierce, the gap isn't that big anymore.
A: 那福利呢？
Nà fúlì ne?
What about benefits?
B: 大公司的福利是初创公司的两倍不止，这方面差距还是很明显。
Dà gōngsī de fúlì shì chūchuàng gōngsī de liǎng bèi bù zhǐ, zhè fāngmiàn chājù hái shì hěn míngxiǎn.
The big company's benefits are more than twice those of the startup. The gap in this area is still very obvious.
A: 那你不后悔？
Nà nǐ bù hòuhuǐ?
You don't regret it?
B: 不后悔。成长空间比大公司大得多，这对我来说更重要。
Bù hòuhuǐ. Chéngzhǎng kōngjiān bǐ dà gōngsī dà de duō, zhè duì wǒ lái shuō gèng zhòngyào.
No regrets. The room for growth is much greater than at a big company, and that matters more to me.
A: 有道理。每个人的程度和目标不一样，没办法直接比。
Yǒu dàolǐ. Měi gè rén de chéngdù hé mùbiāo bù yīyàng, méi bànfǎ zhíjiē bǐ.
Makes sense. Everyone's situation and goals are different; you can't compare directly.
Extended Reading
根据最新数据，中国的电动汽车销量是五年前的将近十倍。相比传统燃油车，电动车的维护成本低得多，但购买价格目前还是高出不少。不过两者的价格差距正在缩小，专家估计再过几年，电动车的价格和燃油车差不多。消费者对电动车的接受程度也在明显提高，这对整个行业是一个积极的信号。

According to the latest data, China's electric vehicle sales are nearly ten times what they were five years ago. Compared to traditional fuel-powered cars, maintenance costs for EVs are much lower, but purchase prices are still considerably higher. However, the price gap between the two is narrowing. Experts estimate that in a few more years the price of EVs will be about the same as fuel cars. Consumer acceptance of electric vehicles is also increasing noticeably, which is a positive signal for the whole industry.

Cultural Note
Comparisons in Chinese business and academic contexts are rarely casual. Citing specific multiples (是...的N倍) or data-backed degree differences signals credibility. In negotiations, Chinese professionals often use 差不多 strategically to soften a position rather than to state objective fact. Saying 我们的价格和市场价差不多 can mean anything from "nearly identical" to "in the same ballpark," deliberately leaving room for interpretation. Recognizing this ambiguity is as important as producing the grammar correctly.
