原文
Instead of lying awake worrying, we’re often told to “sleep on it” when making big or small decisions.
There’s actually a scientific basis for this advice.
Sleep ____1____ influence our response to emotional situations, and helps us to manage our mental health.
To understand ____2____ sleep and emotions are so connected, it’s important to first understand what happens in the brain when we come across ____3____ emotive.
Two main brain regions interact to create emotional responses.
The first is the limbic system (边缘系统) ____4____ (locate ) deep in our brain.
This acts as our emotion center ____5____ quickly considers a situation to make a judgement about it and helps us to decide how to react.
It helps us react quickly in certain situations—for example, when we come across a dangerous animal.
But most of the time we need to adjust our immediate emotional response.
This is where the second region—the prefrontal cortex (前额皮质)—comes in.
Located just behind our forehead, this region ____6____ (help) us to increase or decrease our emotional responses as necessary.
So if we see a predator (such as a bear) in the zoo, the prefrontal cortex tells us we don’t need to panic ____7____ it’s in a cage.
These regions need to be well-connected ____8____ effectively generate and adjust our emotional responses.
This is where sleep comes in.
When we’re sleep deprived (睡眠不足), the connections between these areas weaken, making the reaction in the limbic system ____9____ (strong).
Sleep loss not only increases our reaction ____10____ stressful events during the day, but it also makes these reactions harder to change.
解析
1 主谓宾完整，需要情态动词，表示睡眠能够影响我们对情感情况的反应，故填 can
2 空处及之后的内容为动词“understand”的宾语从句，从句使用了“主系表”结构，成分齐全，结合句意可知这里表示“理解为什么睡眠和情绪如此相关”，空处意思为“为什么”，故填 why
3 come across“偶然遇见”为及物动词，指代某些情感性的事物 故用something
4 过去分词作后置定语，修饰limbic system，位于我们大脑深处的边缘系统，故填 located
5 空处及之后的内容为非限制性定语从句，在定语从句中作主语，所以空处用关系代词which。故填which
6 本段所描述的是客观事实，所以时态用一般现在时。空前“this region”为句子的主语，是第三人称单数，所以空处用单三。故填helps
7 结合句中“we don’t need to panic”和“it’s in a cage”可知，空后的内容是前文“我们不要恐慌的原因”，所以空处用连接词because“因为”。故填because
8 不定式可以表示目的，短语in order to“为了”，也可以表示目的。需要连接良好，是为了有效地产生和调整我们的情绪反应，故填to/in order to
9 当我们睡眠不足时，这些区域之间的联系减弱，使边缘系统的反应更加强烈。根据上文可知，因为睡眠不足，使边缘系统的反应相比变得更加强烈。所以空处用比较级。故填stronger
10 短语reaction to“对……做出反应”。故填to
逐句翻译
1 Instead of lying awake worrying, we're often told to "sleep on it" when making big or small decisions.
我们经常被告知在做大小决定时，与其熬夜担心，不如"睡一觉再说"。
2 There's actually a scientific basis for this advice.
这种建议实际上有科学依据。
3 Sleep (can) influence our response to emotional situations, and helps us to manage our mental health.
睡眠能影响我们对情感情况的反应，并帮助我们管理心理健康。
4 To understand (why) sleep and emotions are so connected, it's important to first understand what happens in the brain when we come across (something) emotive.
为了理解为什么睡眠和情感如此相关，首先了解当我们遇到某些情感性事物时大脑中发生什么很重要。
5 Two main brain regions interact to create emotional responses.
两个主要大脑区域相互作用产生情感反应。
6 The first is the limbic system (边缘系统) (located) deep in our brain.
第一个是位于我们大脑深处的边缘系统。
7 This acts as our emotion center (which) quickly considers a situation to make a judgement about it and helps us to decide how to react.
这作为我们的情感中心，它快速考虑情况以做出判断并帮助我们决定如何反应。
8 It helps us react quickly in certain situations—for example, when we come across a dangerous animal.
它帮助我们在某些情况下快速反应——例如，当我们遇到危险动物时。
9 But most of the time we need to adjust our immediate emotional response.
但大多数时候我们需要调整我们的即时情感反应。
10 This is where the second region—the prefrontal cortex (前额皮质)—comes in.
这就是第二个区域——前额皮质——发挥作用的地方。
11 Located just behind our forehead, this region (helps) us to increase or decrease our emotional responses as necessary.
位于我们前额后方，这个区域帮助我们根据需要增加或减少我们的情感反应。
12 So if we see a predator (such as a bear) in the zoo, the prefrontal cortex tells us we don't need to panic (because) it's in a cage.
所以如果我们在动物园看到捕食者（如熊），前额皮质告诉我们不需要恐慌，因为它在笼子里。
13 These regions need to be well-connected (in order to) effectively generate and adjust our emotional responses.
这些区域需要很好地连接以便于有效地产生和调整我们的情感反应。
14 This is where sleep comes in.
这就是睡眠发挥作用的地方。
15 When we're sleep deprived (睡眠不足), the connections between these areas weaken, making the reaction in the limbic system (stronger).
当我们睡眠不足时，这些区域之间的连接减弱，使边缘系统的反应更强。
16 Sleep loss not only increases our reaction (to) stressful events during the day, but it also makes these reactions harder to change.
睡眠不足不仅增加我们对白天压力事件的反应，还使这些反应更难改变。
