It can 16 suddenly, progressing from a feeling of uneasiness to a cold sweat.
答案：(D) strike
strike 用於疾病、災難時是「突然發作、突然侵襲」，與 suddenly 及後面的 progressing from a feeling of uneasiness to a cold sweat 完全吻合；crash（碰撞）、flush（沖洗、臉紅）、burst（爆裂，須接 into／out）都不合。
答對率 31%，鑑別度 14。
a disease／disaster + strike。strike 你記的是「打、擊」（strike a ball 擊球）與「罷工」（go on strike）。它還有一個用法課本少提：主詞換成疾病、災難、天災時，意思是「突然發作、突然侵襲」，這一義在新聞與健康類文章裡到處都是。同義的說法是 hit，兩個字可以互換：An earthquake struck／hit the area.（地震侵襲該地區。）
主詞 It (motion sickness) 指的是前一句的動暈症，空格後面緊接 suddenly，再接 progressing from a feeling of uneasiness to a cold sweat（從一陣不適逐漸演變成冒冷汗）——整句描述的正是症狀突然發作、然後一路惡化。疾病當主詞、後面接 suddenly，答案就鎖定 strike。一句記完：The typhoon struck the island just after midnight, and classes were called off at dawn.（颱風在午夜剛過時侵襲本島，天一亮就宣布停課。）〔情境取材自 114 學測作文題：颱風停課〕
crash 是「碰撞、墜毀」，用在車輛或系統；flush 是「沖水、臉紅」，雖然跟臉有關，講的是臉紅不是發病；burst 是「爆裂」，要表達突然發生必須接介系詞（burst into tears 突然大哭、burst out laughing 突然大笑），不能像本句這樣單獨用。
a disease strikes（疾病發作）、a disaster strikes（災難侵襲）、be struck by lightning（被閃電擊中）、strike a balance（取得平衡）、go on strike（罷工）、motion sickness（動暈症）。
If you have ever been sick to your stomach on a rocking boat or a bumpy car ride, you know the discomfort of motion sickness. It can 16 suddenly, progressing from a feeling of uneasiness to a cold sweat. Soon, it can lead to dizziness, nausea, and vomiting.
Motion sickness occurs when the signals your brain receives from your eyes, ears, and body 17 . Your brain doesn't know whether you are stationary or moving when these parts send conflicting information: One part of your balance-sensing system detects that your body is moving, but the other parts 18 . Your brain's confused reaction makes you feel sick. You may experience the discomfort from the motion of cars, boats, or amusement park rides. You may also get sick from playing video games, or looking through a microscope.
You can take some 19 to help avoid the discomfort. If you are traveling, reserve seats where motion is felt the least, such as the front row of a car or forward cars of a train. Looking out into the distance from the vehicle can help 20 . You can also take medicine before your ride to avoid or reduce nausea and vomiting.
