Then an icy chill skittered up my spine as something with a rough surface 5 (slide) slowly onto my ankles. My heart jumped and I froze. Rattlesnake! Flashed across my mind, searing my thoughts with the old timers’ tales about these deadly reptiles 6 inhabit the hills in Franklin Count — and their sometimes lethal bite.

I prayed sincerely to God for safety, and asked for forgiveness. Images of my family flashed before my eyes. The crawling, ticklish movement suddenly stopped. The rattler now lay partially lengthwise along my upper legs and buttocks. Not a muscle twitched as I searched my mind for a way out of the predicament. I had just about decided to catapult myself from the sleeping bag when the snake slowly crawled over my hip and began to coil (盘绕) its full length into the warm confines of my lower stomach, groin and thighs. No movement was made by cither the rattler or me for 1 seemed like an eternity. My mouth was like cotton, and I longed 2 (emit) a long, deep breath. Then waves of goose pimples rippled up my stomach as the snake began to make another move. Oh, God, deliver me, I prayed. I lay frozen, my heart 3 (pound) in my ears. 【答案】 1．spread 2．To 3．as if/as though 4．should 5．slid 6．that/which 7．it 8．what 9．to emit 10．pounding 【导语】本文是一篇记叙文。文章主要讲述了作者一次在密西西比州西南部山区狩猎白尾鹿时遭遇响尾蛇的惊险经历。 1．考查非谓语动词。句意：晚餐吃完沙丁鱼、饼干、奶酪、洋葱和柠檬水后，我们回到橡树下铺着的鹅绒睡袋里。句中谓语是retired，空格处用非谓语动词，bags和spread之间是逻辑动宾关系，因此空格处用过去分词，表被动，故填spread。 2．考查介词。句意：伴随着偶尔掉落的橡子扑通扑通的声音，Joey很快就睡着了。to the tune of意为“和着……的曲调”，因此空格处用介词to，位于句首的单词首字母大写，故填To。 3．考查表语从句。句意：我仿佛感觉到了内心深处的危险信号。由“I had felt a danger signal deep within me”可知，句子表示“我仿佛感觉到了内心深处的危险信号”，空格处意为“仿佛”，用as if或as though引导表语从句，故填as if或as though。 4．考查情态动词。句意：我侧身躺下，一只胳膊交叉在头下，意识到事情并不像它们应该的那样。空后be是原形，空格处用情态动词，句子表示“意识到事情并不像它们应该的那样”，空格处意为“应该”，情态动词用should。故填should。 5．考查动词时态。句意：然后，一股冰冷的寒意掠过我的脊柱，一个表面粗糙的东西慢慢地滑到我的脚踝上。空格处是谓语，由skittered可知，时态是一般过去时，空格处用过去式slid，故填slid。 6．考查定语从句。句意：响尾蛇！我的脑海中突然闪过关于富兰克林县山丘上这些致命爬行动物的古老传说，以及它们有时致命的咬伤，这些传说像烙印一样灼烧着我的思绪。空格处引导的是限制性定语从句，从句中缺少主语，先行词reptiles是动物，因此空格处是that或which。故填that或which。 7．考查代词。句意：我喘着气，想知道我是否散发出一种恐惧的气味，可能会引起它的攻击。根据语境可知，空格处指代“响尾蛇”，用it，故填it。 8．考查宾语从句。句意：响尾蛇和我都一动不动，似乎过了很长一段时间。空格处引导的是宾语从句，从句中缺少主语，此处表示“响尾蛇和我都一动不动，似乎过了很长一段时间”，因此空格处用what引导宾语从句。故填what。 9．考查非谓语动词。句意：我的嘴干燥无力，我渴望深深地吸一口气。long to do sth.是固定短语，意为“渴望做某事”，因此空格处用不定式to emit。故填to emit。 10．考查非谓语动词。句意：我一动不动地躺在那里，心砰砰直跳。句中谓语是lay，空格处用非谓语动词，heart和pound之间是主谓关系，因此空格处用现在分词，表主动，故填pounding。 C (24-25高二上·上海育才中学·期中) Directions: After reading the passage below, fill in the blanks to make the passage coherent and grammatically correct.
