Even if I get a promotion at my company, it's likely to be less sizable than if I were to get a job elsewhere.
即使我在公司获得晋升，其规模也可能比我在其他地方找到工作要小。
"than if I were to get a job elsewhere" 构成比较从句,由 "than" 引导,承接前面的比较级 "less sizable",表示"比起如果我在别处找工作"。该结构存在省略,完整形式为 "than it would be if I were to get a job elsewhere"。
On average, people who changed jobs have almost always gotten better pay raises than those who stayed.
平均而言，换过工作的人获得的加薪幅度几乎总是高于留在原岗位的人。
“than those who stayed”引出比较对象，说明换工作者的加薪与留任者的加薪进行比较；其中“those who stayed”内部还含有修饰“those”的限制性定语从句。
The study found that when people ate a highly processed diet, they consumed about 500 more calories per day than they did when they ate a less processed diet.
研究发现，人们食用高度加工的饮食时，每天摄入的热量比食用加工程度较低的饮食时多约500卡路里。
“than”引导含谓语“did”的比较从句，与前面的“consumed about 500 more calories per day”构成比较；“did”代替前面的“consumed”，避免重复。
Grit tells us that the door is open wider than we first thought possible.
毅力告诉我们，门比我们最初认为的可能开得更宽。
由 than 引导的比较从句，完整形式为 than we first thought (it was) possible，与前文 wider 构成比较，从句中省略了 it was（it 指代 the door is open 的程度）。
We found that enjoyment predicted people's goal persistence two months after setting the goal far more than how important they rated their goal to be,
我们发现，在设定目标两个月后，愉悦感对人们目标坚持性的预测作用远比他们对自己目标重要性的评价要大得多，
该分句由比较标记 "than" 引出，和前面的 "far more" 构成 "far more than ..." 比较框架。"than" 后接一个由 "how" 引导的间接疑问结构 "how important they rated their goal to be"，该结构整体作为比较基准。
Interestingly, they found that men were far more likely to speak in the abstract than were women.
有趣的是，他们发现男性远比女性更有可能进行抽象表达。
than 引导的比较从句,与前面的 "far more likely" 构成比较结构。此处发生倒装,谓语 "were" 提到主语 "women" 之前,完整形式应为 "than women were (likely to speak in the abstract)",省略了与主句重复的部分 "likely to speak in the abstract"。倒装是为了保持句子平衡或强调。
They found that participants in a high-power interviewer role were more likely to give abstract descriptions of behaviors than were participants in a low-power interviewee role.
他们发现，担任高权力面试官角色的参与者比担任低权力被面试者角色的参与者更有可能对行为给出抽象描述。
than引导的比较从句,与前面"more likely"构成比较结构。从句采用了倒装语序"than were participants"(were提前),补全为"than participants in a low-power interviewee role were (likely to give abstract descriptions)"。从句有完整主谓结构。
When an object did not drop out of the bottom of a rattling container, they looked at it for a longer time than they did when the container behaved as expected.
当一个物体没有从发出嘎嘎声的容器底部掉出来时，他们看它的时间比容器表现符合预期时看的时间更长。
"than" 对应前面的比较级 "longer",引出比较对象;"they did" 中 "did" 代替前面的 "looked at it",表示他们看的时间比另一种情况下更长。
They believe that women are paid less than men for doing the same job.
他们认为女性做相同工作时获得的报酬少于男性。
该从句以 "than" 引导比较结构。在 "women are paid less than men" 中,"than men" 引导比较从句,补全后为 "than men are (paid)",省略了与主句重复的谓语部分。这是典型的含谓语(隐含)的 than 比较从句。
At the same time, however, young working women are less likely than men to aim at top management jobs: 34% say they're not interested in becoming a boss or top manager; only 24% of young men say the same.
然而，与此同时，年轻的职业女性比男性更不可能瞄准高层管理职位：34%的人说她们对成为老板或高层经理不感兴趣；只有24%的年轻男性这么说。
这是比较从句,由"than"引导。完整形式是"than men are (likely) to aim at top management jobs",省略了"are likely",只保留"to aim"部分。从句主语"men",谓语省略,不定式"to aim"是补足语。
But is juicing really as healthy as we think?
但是榨汁真的像我们认为的那样健康吗？
这是"as...as"比较结构中的比较从句部分。第一个"as"为程度副词修饰"healthy",第二个"as"为从属连词引导比较从句"as we think"。从句完整形式应为"as we think (it is healthy)",其中"it is healthy"因与前文重复而省略,仅保留"we think"。该从句建立了"juicing的实际健康程度"与"我们认为的健康程度"之间的比较关系。
Contrary to popular belief, consumers aren't as smart as they like to believe.
与普遍看法相反，消费者并没有他们自以为的那么聪明。
这是"aren't as smart as..."中的比较分句，由第二个"as"引导，表示消费者的实际聪明程度与他们自认为的程度进行比较。"they like to believe"中"believe"后的内容被省略，可理解为"believe themselves to be smart"。
On the other hand, advocates of organic farming argue yields and efficiency could be significantly improved if the food industry devoted as much research and money to organic farming as it does conventional agriculture.
另一方面，有机农业的倡导者认为，如果食品行业像对待传统农业那样投入同等规模的研究和资金用于有机农业，其产量和效率将会得到显著提高。
该分句是"as much ... as"比较结构的后半部分，含有主语"it"和谓语"does"；"does"替代前面的"devoted"，比较有机农业与传统农业获得的研究和资金投入。
The colour of the wrapper is similar, as are the illustrations of the features.
包装纸的颜色是相似的，特征的插图也是如此。
由as引导的比较从句,采用倒装结构"as+系动词+主语"(正常语序为"as the illustrations of the features are")。该从句与前面主句构成隐含的"as...as"比较框架(完整形式可理解为"similar as the illustrations are"),省略了第一个as与similar的重复。从句表达"特征插图也(相似)",与主句形成平行对比。
"As much as talent counts, effort counts twice," says Duckworth in Grit.
“天赋固然重要，但努力的重要性是天赋的两倍，”达克沃斯在《坚毅》一书中说道。
"As much as" 引导比较从句,表示程度比较,意为 "和...一样多/重要"。此处表示 "talent counts(天赋重要)的程度有多少",为后文 "effort counts twice" 提供比较基准。
But contrary to all the publicity that everyone needs more protein, most Americans get twice as much as they need.
但是与所有人都需要更多蛋白质的宣传相反，大多数美国人摄入的量是他们所需的两倍。
比较从句,由第二个"as"引导,与前面的"as much"构成"as...as"比较框架。从句主语"they"(指代"most Americans"),谓语"need",宾语省略(指代"much"或理解为省略的量),表示"他们所需要的量"。该从句与"twice"和前面的"as much"共同构成倍数比较结构"倍数+as...as"。
Their stress levels are actually the same as those experienced by the children who yell and scream.
他们的压力水平实际上与那些大喊大叫的孩子所经历的压力水平相同。
as引导比较从句，与主句的same构成"the same as"比较框架。从句主语those指代stress levels，谓语are experienced省略(完整形式为"as those [stress levels are] experienced by...")，仅保留过去分词experienced及其by短语。从句内嵌套定语从句修饰the children。
The body of KaiOS phones is as basic as it gets.
KaiOS手机的机身就像它本身一样基础。
"as it gets"是比较从句,与前面的"as basic"构成"as...as"比较框架,表达"尽可能基本/达到极致的基本"。从句中"it"指代"the body","gets"表示"变得/达到",从句完整为"as (basic as) it gets (basic)",省略了重复的形容词。这是固定用法"as...as it gets",意为"到了极点"。
M: I'm not so sure that sleep is nearly as important as people always say it is.
M：我不是那么确定睡眠几乎像人们总是说的那样重要。
该从句由第二个 "as" 引导（"as … as" 结构中的后一个 as 兼作连词），对比的基准是 "people always say"（人们一直所说的程度）。从句主干为 "people say it is"，其中 "it" 指代 "sleep"，"is" 后省略了比较的形容词 "important"（完整形式为 "people always say it is [important]"）。该省略是比较从句的典型特征，避免重复。
Keeping your name and joining it to your husband's through hyphenation is as legal as simply adopting his name or as simply keeping your own and leaving his out of the picture entirely.
保持你的姓氏并通过连字符将其与你丈夫的姓氏连接起来，与仅仅采用他的姓氏一样合法，或者与仅仅保留你自己的姓氏并完全不提及他的姓氏一样合法。
第二个as引导比较从句，从句部分包含由or连接的两个并列动名词短语"simply adopting his name"和"as simply keeping your own and leaving his out of the picture entirely"。注意第二个并列成分前有重复的as，形成"or as"结构。后者内部又包含由and连接的两个并列动名词"keeping your own"和"leaving his out of the picture entirely"。整个从句与主句表语"as legal"构成as...as比较框架，表达"与...一样合法"的比较关系。
In a review of 14 studies that looked at physical activity and academic performance, investigators found that the more children moved, the better their grades were in school, particularly in the basic subjects of math, English and reading.
在一项对14项研究的综述中，这些研究考察了身体活动和学业表现，研究者发现儿童活动量越大，他们在学校的成绩就越好，尤其是在数学、英语和阅读这些基础学科中。
"the more..., the better..."构成比较从句,表示比例关系:"孩子们运动越多,成绩越好"。前半句"the more children moved"为条件/时间分句,后半句"the better their grades were"为结果分句且采用倒装语序(were提前)。"particularly in..."为补充说明。
The higher their educational level, the more likely they are to delay retirement.
他们的教育水平越高，他们就越有可能推迟退休。
这是"the+比较级…, the+比较级…"结构中的前半部分比较从句，表示条件或程度。"The higher"是比较级形式，"their educational level"是该从句的主语，省略了系动词"is"（完整形式为"The higher their educational level is"）。该从句作状语修饰主句，表示"教育水平越高"这一条件。
"The more creative we are, the more beautiful and delicious our future will be."
"我们越有创造力，我们的未来就会越美丽和美味。"
这是"the+比较级…the+比较级"结构的前半部分比较从句,含完整主谓结构"we are creative",其中"the more creative"是比较级形式作表语。该从句与后半部分"the more beautiful and delicious our future will be"构成呼应,表达"我们越有创造力"这一条件或程度。
The more horrible the school circumstances, the more important pleasure is to achieving any educational success.
学校环境越糟糕，快乐对于取得任何教育成功就越重要。
该从句使用"the+比较级"结构,与后面主句的"the more important"构成完整的"the+比较级…, the+比较级…"比较框架,表示"学校环境越糟糕"。从句主干为"the school circumstances (are) horrible",其中系动词"are"被省略,这是该句型的常见省略现象。
A phantom jam begins when a car in dense traffic slows down even slightly, which causes the car behind that vehicle to slow even more—and the slowing action spreads backward through the lane of traffic like a wave, getting worse the farther it spreads.
幽灵堵车始于密集车流中的一辆车即使轻微减速，这会导致该车辆后方的车减速更多——并且这种减速行为像波浪一样在车道中向后传播，传播得越远情况越糟。
"the farther it spreads" 含有主语 "it" 和谓语 "spreads",表示程度随传播距离变化。它与前面的 "getting worse" 构成省略式关联,可理解为 "the farther it spreads, the worse it gets",属于 "the + 比较级... the + 比较级..." 比较结构的一部分。

粉色越深，雄性被认为越有吸引力；雄性年龄越大，它将拥有越多粉色。
这是"the+比较级..., the+比较级..."结构中的前半部分比较从句。"the pink"是名词化用法指代粉色程度,"deeper"是比较级形容词作表语,省略了系动词"is"(完整形式为"the pink is deeper")。该从句表示条件或程度,修饰后续的主句部分。
And this is more and more true, the higher up the scale you go.
并且这种情况越来越真实，你所处的层级越高越是如此。
这是"the+比较级..., the+比较级..."结构中的后半部分(条件分句)。"the higher"是比较级形式,"up the scale"是方向状语修饰"higher","you go"是完整谓语结构。整个从句表达"你在等级上走得越高"这一条件变量,与主句的"more and more true"形成正相关的比较关系。这种结构中,"the"不是冠词而是程度副词(by how much的意思),引导比较从句。
The more money a project sought, the lower the chance it reached its goal, the researchers found.
研究人员发现，一个项目寻求的资金越多，它达成目标的可能性就越低。
该分句是 "the more..., the lower..." 比较相关结构的前一项,内部有完整主谓 "a project sought","more money" 是被提前的比较成分,表示"项目寻求的钱越多"。
Options are more valuable the longer they can be held.
期权持有时间越长，其价值就越高。
这是 "the+比较级…the+比较级" 结构的后半部分,引导比较从句。完整框架为 "(the) more valuable the longer...",省略了前半句的 "the",但框架仍成立。从句 "they can be held" 含完整主谓结构,"the longer" 作时间状语修饰 "can be held",表示 "持有时间越长"。
And this is more and more true, the higher up the scale you go.
而且这种情况越来越真实，你所处的等级越高越是如此。
这是 "the+比较级..., the+比较级..." 结构的后半部分,省略了前面的 "the more true (it is)",形成对称的比较从句。"the higher" 是比较级结构,"you go" 是完整谓语,"up the scale" 作状语修饰 "go"。
Hiring managers said training was three times more likely to get them to hire applicants over age 45 than, say, government subsidies(补贴).
招聘经理表示，培训比政府补贴（比如说）更有可能让他们雇佣45岁以上的申请人，可能性是政府补贴的三倍。
该分句由 "than" 引导,构成 "three times more likely... than..." 比较框架的后半部分。虽然表面上省略了谓语,但完整形式应为 "than government subsidies were (likely to get them to hire applicants)",是典型的省略式比较从句。"say" 是插入语,表"比如说"。
The team at Stanford investigated the aquifers(地下蓄水层) below this depth and found that reserves may be triple what was previously thought.
斯坦福大学的团队调查了该深度以下的地下蓄水层，并发现储量可能是之前认为的三倍。
由连接代词 "what" 引导的比较从句,提供 "triple" 的比较基准。"what" 在从句中充当主语,融合了先行词和关系代词的功能,表示"之前被认为的(储量)",具有自由关系词性质。该从句在 "be triple" 结构中充当比较对象,表达倍数关系。
For them, output by 2029 is likely to be around 3.5 times what it was when Keynes was writing.
对他们而言，到2029年的产出可能会是凯恩斯写作时的大约3.5倍。
该从句由融合关系词"what"引导，整体作为倍数比较结构"3.5 times"的比较基准，相当于"the amount that it was"。这是典型的倍数比较从句，"times + what从句"构成完整的比较框架。从句内部"it was"后省略了表语，并嵌套了一个时间状语从句"when Keynes was writing"进一步限定时间。
There would be no mystery in this if Keynes had been wrong about the power of technology to increase the economy's productivity, which he thought would lead to a standard of living "between four and eight times as high as it is today."
如果凯恩斯关于技术提升经济生产力的力量的观点是错误的，那么这就不会有什么奥秘了，他认为这种生产力提升会带来“达到今天四倍到八倍之间的生活水平”。
倍数比较从句，"between four and eight times" 为倍数表达，"as high as it is today" 构成比较框架。从句主干为 "it is (high) today"，省略了比较对象 high。该从句修饰 "a standard of living"，说明生活水平的提升幅度。
It costs more than twice as much as a car ride.
它的花费是乘车的两倍多。
这是一个倍数比较从句,框架为 "more than twice as much as",其中 "more than" 修饰倍数词 "twice",表示"超过两倍","as much as a car ride" 构成比较对象。从句中隐含谓语 "(a car ride) costs",这是典型的比较从句省略形式,完整形式应为 "more than twice as much as a car ride costs"。
For example, the United Nations reported that women do nearly three times as much unpaid domestic work as men.
例如，联合国报告称，女性从事的无偿家务劳动几乎是男性的三倍。
由 "as" 引导的比较从句，与前面的 "three times as much unpaid domestic work" 构成倍数比较框架 "倍数 + as much ... as"。从句省略了谓语 "do"（完整为 "as men do"），通过省略避免重复，符合比较从句的常见省略模式。
Tap water consumption is growing at roughly the same pace (UK consumers still drink almost three times as much tap water as bottled water).
自来水消费正以大致相同的速度增长（英国消费者仍然饮用几乎三倍于瓶装水的自来水）。
倍数比较结构"three times as much... as..."，第一个"as"前为倍数词"three times"修饰"as much tap water"，第二个"as"引导比较从句"as bottled water"（完整形式应为"as they drink bottled water"，谓语省略）。从句含隐含谓语，构成完整比较。
Electric bike riders have to follow all the same rules as you would if you were in an automobile.
电动自行车骑手必须遵循与你在汽车中时相同的所有规则。
比较从句，由"as"引导，与主句中"the same...as"形成呼应（完整结构为"the same rules as you would follow"）。从句主语"you"，谓语"would"（省略了与主句重复的"follow"），表示"就像你（遵守的规则）一样"。从句内部嵌套条件状语从句"if you were in an automobile"。
Some people may argue that this is merely reported data, and they say many men feel the same pressures as women in terms of fulfilling responsibilities at work and home.
有些人可能会争辩说这仅仅是报告的数据，并且他们说许多男性在履行工作和家庭责任方面感受到与女性相同的压力。
as 引导的比较从句，与前面的 "the same pressures" 构成 "the same...as" 比较框架。从句内部省略了谓语 "feel the same pressures"，仅保留主语 "women"。完整还原为 "as women (feel the same pressures)"。
According to a new study from Cornell University's Food and Brand Lab, small non-food rewards—like the toys in McDonald's Happy Meals—stimulate the same reward centers in the brain as food does.
根据康奈尔大学食品与品牌实验室的一项新研究，小型非食品奖励——如麦当劳开心乐园餐中的玩具——会像食物一样刺激大脑中相同的奖励中心。
这是比较从句,由 "as" 引导,与主句中的 "the same" 呼应形成 "the same...as" 比较框架。从句中 "food" 是主语,"does" 是替代动词(代替 "stimulates the same reward centers in the brain"),完整表达为 "as food stimulates the same reward centers in the brain"。比较从句的 evidence 包含完整的 "the same...as" 结构。
Human numerical instincts are not so superior to those of other mammals as is generally believed.
人类的数字本能并不像人们普遍认为的那样比其他哺乳动物的数字本能优越。
"as is generally believed" 为比较从句，与主句中的 "not so...as" 结构呼应，补充说明比较的参照标准。采用倒装结构（正常语序为 "as it is generally believed"），"is believed" 构成完整谓语，符合比较从句定义。
However, it's also important to realize that not all of your plans will turn out exactly as you wish.
然而，意识到并非所有你的计划都会完全如你所愿地实现也是很重要的。
此从句由 as 引导，构成比较结构，表示程度相同的比较关系。完整理解为"turn out exactly as (exactly as) you wish (them to turn out)"，即计划结果的程度与期望程度相同。虽然结构上看似简化，但本质上是 as…as 比较框架的省略形式，用于修饰"exactly"表达程度比较。
It should be taught the same way as English is taught.
它应该被以和英语被教授的同样方式教授。
由"as"引导的比较从句，与主句"the same way"构成"the same...as"比较结构。从句内部为完整主谓结构"English is taught"（被动语态），表示教授方式应与英语教学相同。此处"as"引导的是比较从句而非方式状语从句，因为它与"the same"形成固定的比较框架，强调方式的相同性而非单纯描述方式。
As solar panels get cheaper, the world is likely to see more skyscrapers covered in solar panels, collecting energy much like trees do.
随着太阳能电池板变得更便宜，世界可能会看到更多覆盖着太阳能电池板的摩天大楼，它们像树木一样收集能量。
"much like trees do" 是比较从句,"like" 在此引导比较结构(much like = very much as),从句主语 "trees",谓语 "do" 是替代动词(代替 collect energy),表示 "像树木那样收集能源"。"much" 修饰 "like" 强化相似程度。
Initially, kids learn numbers much like they learn letters.
最初，孩子们学习数字非常像他们学习字母。
由 "much like" 引导的比较从句，"like" 后接完整分句 "they learn letters"（主语 they、谓语 learn、宾语 letters），表达方式上的类比 "就像……一样"。"much" 强化比较程度。该从句在主句中充当方式状语，说明 "learn numbers" 的方式类似于 "learn letters"。
