Section A 选词填空

　　The sheets are damp with sweat. You're cold, but your heart is racing as if an assailant just chased you down a dark street. It was just a nightmare, you tell yourself; there's nothing to be afraid of. But you're still filled with __26__. Given how unsettling and haunting nightmares can be, is there a way for dreamers to __27__, or even turn off, these bad dreams as they happen? Research is ___28___, but some studies suggest that people who can master lucid dreaming — that is, the ability to be __29__ that a nightmare is happening and possibly even control it without waking up — may hold the __30__. Nightmares are part of the human experience, especially for kids. Doctors ___31__ don't consider occasional nightmares a problem, but there are options for people whose nightmares occur frequently and negatively affect their lives during the day. These can be symptoms of nightmare disorder, a sleep disorder that can stem from trauma, stress and certain drugs. To treat nightmare disorder, there are a number of medications and therapies that are backed by ___32___ research, according to the American Academy of Sleep Medicine, which analyzed the available research on the treatment of nightmare disorder in a 2010 __33__ published in the Journal of Clinical Sleep Medicine.

What we do know is that people __35__ to have different kinds of nightmares at different points during the sleep cycle.

　　fear

　　缺名词。前文在描述nightmare“噩梦”的场景：出汗sweat弄湿了被子sheets，被行凶者assailant在漆黑的街上追赶。所以充满恐惧“fear”。

　　avoid

　　to 后面加动词原形，且后面有or，所以意思上并列turn off(关掉)，避免avoid噩梦发生。

　　limited

　　主系表结构，is后加形容词。上文提出问题：人们是否可以阻止噩梦发生，此句为回答，且28空后面“but”转折——但是有人可以掌控梦境。所以28空应是否定含义，固limited(研究结果是有限的)。

　　aware

　　be动词后接形容词。本句是对上半句掌控梦境的继续阐述——“这种能力就是“意识到aware”梦境正在发生，继而控制梦境”。

　　answer

　　空前有定冠词the，后接名词。该句主语为破折号前的“people who can master lucid dreaming”，掌控梦境的人可能有这个问题的答案，固answer。

　　typically

　　句子成分完整，填副词。注意：typically在这里为“通常”，而非“典型”之意。通常医生不认为偶尔的噩梦是个问题。

　　rigorous

　　research为名词，前缺少形容词进行修饰。back在此为动词“支持”之意，疗法therapies有研究research支持，固rigorous“严谨的”符合题意。

　　暂缺

　　review

　　前有a 2020，固缺少一个可数名词单数，后有published出版，所以应为“review报告，述评”。

　　tend

　　该句缺动词，且空后有to，所以需要不及物动词，tend to 固定搭配“通常，往往会”。
