解析：第一代可穿戴智能设备旨在帮助人们了解身体活动,现在医疗业正在寻找方法使用智能设备来监控有慢性疾病的病人。①考查非谓语动词。beaimedatdoingsth.为固定用法,空处作at的宾语,故应填动词ing形式。②考查名词复数。对医院来说,在病人回家之后了解他们的动态越来越重要。patient为可数名词,其前没有限定词,故应用复数形式。③考查形容词。分析句子结构可知,空处作表语,且其前有increasingly修饰,故填形容词。④考查非谓语动词。医疗业正在寻找方法使用智能设备来监控有慢性疾病的病人。由语境可知,此处作目的状语,因此用动词不定式。⑤考查介词。根据语境及空前的Founded可知,此处表示"由……创建",故应用by。⑥考查代词。结合语境并分析句子结构可知,空处作定语,故应填形容词性物主代词is。⑦考查主谓一致和时态。此处陈述客观事实,故应用一般现在时,主语为第三人称单数,故应填sends。⑧考查定语从句。分析句子结构可知,空处引导定语从句,并在从句中作主语,先行词是apatch,指物,故填that/which。⑨考查主谓一致、时态和语态。根据语境,此处表示过去发生的动作,应用一般过去时,主语为setup,为第三人称单数,且与design为被动关系,故用一般过去时的被动语态wasdesigned。⑩考查连词。由语境可知,空处前后句子为转折关系,故应填but。17.答案：①what②observed③voluntarily④a⑤locked⑥uncertainty⑦shouldroll⑧of⑨where⑩themselves

解析：①考查固定句型。句意:仁慈之于灵魂,犹如阳光之于庄稼。固定句型:AistoBwhatCistoD"A对B就像C对D一样"。故填what。②考查时态。句意:温斯顿•丘吉尔曾经说过……。根据时间状语once可知空处要用一般过去时态,故填observed。③考查副词。句意:许多活动义务帮助老人、残疾人和儿童。修饰动词aid,需用副词。故填voluntarily。④考查不定冠词。句意:在快乐给予的阳光下,没有人是一座孤岛。此处表示泛指,且lonely以辅音音素开头。故填a。⑤考查过去分词。句意:有时我们陷入生活的“你死我活的竞争”中,成功的不确定性使我们气馁。固定结构:getlockedin…陷人

,故填locked。⑥考查名词。句意同上。分析句子结构,the用在名词前面,故此处是名词。certain是形容词,意为“确定的”,其名词形式是certainty“确定性”,再结合句意可知这里应该用certainty的反义词。故填uncertainty。⑦考查虚拟语气。句意:考虑到志愿劳动服务的重要性,现在是我们卷起袖子伸出援助之手的时候了。It'stime+that从句,表示“现在是做某事的时候了”,从句用虚拟语气,从句通常用一般过去时或从句谓语用"should+动词原形"。结合题型要求应填rolled。⑧考查介词。句意:关
