11.C 由three -T知，此处用复数形式,thief的复数形式为thieves0
12.C 主语为they,表语应为复数名词，只有C项是正确形式。

13.A there be句型中，be的单复數形式由最靠近它的主语的单复数决定，故选A。

14.A 由前面的“这个男孩口渴了"町推知他想妥喝的东西，故it Ao
15.A Maths是“数学"，作主语时谓语动词用单数。

16.B It is important for sb. to do slh.为因定句式，意为"对某人来说做某事是重妥的
17. C on the land '在陆地上"，under the wate广在水下句意：地球上有很多动物，一些生活在陆地上，一些生活在水下。

18. D stop to do sth.意为‘仔下来去做某事"，stop doing sth.意为“停止做某事"。

由句意“我们必须停止捕杀动物"町知选Do
19. B throw sth. into th已liver"把某物扔进河里符合句意。

20. C provide sb. with sth.为因定短语，意为“给菜人提供某物二
21. B chance'4机会"，advice"建议"，excuse"借口〔business"商业"。

根据文章最后一段的"So my advice is this: If a snake bites you. pick up your phone「'町知选B。

22. A suddenly"突探"，nearly"几乎"，especially"尤其fortunately"幸运地"。

根据文章叙述，应该是"突然"一条坨出现了，咬到了杰克逊芜生的手。

23. C 通过前文Henry Jackson was workuig in a restaurant kitchen「町知故事应该是发生在一家饭馆里，所以本题选择restaurant o
24. B 根据文章含丈町知应该是这条坨爬出了箱子然后“藏"在世子底下，故选择hid （原形hide“隐藏“）。

hung （原形hang、'悬挂J , jumped （原形jump“跳"）,ran （原形miT跑J均与文意不符。

25. D under"在下面、into"进入", towards"朝”。

不能将蛇扔到厨房下面，故排除under;根据前文我们知道这条蛇本来就在厨房内，所以throw…into"扔进（府房）’'和throw…towards"扔向（厨房）’'均不符合逻辑。

故只有D 符合題意，（hrow i（ across （he kitchen意为"把它从厨房的这一边扔向那一边二
26. A stay cool意为“保持冷静〔说的是杰克逊先生保持镇静，用手机给蛇拍了一张照片。

其他形容词noisy （吵闹的）,pleased （滿意的）,afraid （害怕的）都与文意不符。

27. C 从祈文"bit him on the hand"町知"Soon his hand began to ache…（很快他的手开始疼 ......... ）所以选hand。

28. D 通.过"DoctOTS couldn't say what was wrong"和"they didn't know what kind of snake it was’’"「知"医生说不清楚状况"的原因是•'他们不知道这条坨的种类"，所以选becauseo
29. B send sth. to…意为“把某物送/哥到……"，根据文章令义,医生把杰克逊先生拍摄的照片发送到伦敦动物园。

30. C 从全文町知杰克逊宪生给大家的建议是如果蛇咬了你，给它拍照。

所以本题应用il（蛇）的形容词性物主代词its0
