五.单句语法填空
1．【答案】has been updated
【详解】考查时态和语态。句意：到目前为止，数据库已经更新，确保了整个系统中数据的准确性和可靠性。空处为句子的谓语动词，根据时间状语“up to now”可知，句子应用现在完成时，主语The database和动词update之间为被动关系，应用现在完成时的被动语态，主语为单数，助动词用has。故填has been updated。
2．【答案】has been improved
【详解】考查时态、语态和主谓一致。句意：到目前为止，互联网已经改善了简的生活。根据时间状语so far可知，句子时态应用现在完成时，主语Jan’s life与improve之间为被动关系，句子应用现在完成时的被动语态，主语Jan’s life为单数概念，助动词应用has。故填has been improved。
3．【答案】has been invited
【详解】考查时态、语态和主谓一致。句意：到目前为止，王教授已应邀到多所大学讲学。so far和现在完成时连用，主语Professor Wang和动词invite之间是被动关系，故用现在完成时的被动语态，主语表示单数意义，助动词使用has，故填has been invited。
4.【答案】has been destroyed
【详解】考查时态和语态。句意：在过去的50年里，大约17%的雨林因人类活动而被破坏。空格处是谓语动词，主语about 17 percent of rainforest与动词destroy之间是被动关系，所以用被动语态；由时间状语over the past 50 years可知，句子用现在完成时，主语是不可数名词，助动词用has。故填has been destroyed。
5.【答案】has been raised
【详解】考查时态、语态和主谓一致。句意：自一年前以来，已经筹集了大量的资金来帮助那些遭受灾难的人。主语A large quantity of money和raise之间是被动关系，结合时间状语“since a year ago”可知此处使用现在完成时的被动语态，主语是不可数名词，助动词使用has。故填has been raised。
六. 语法填空
1．which 2．means 3．various 4．buildings 5．an
6．be ignored 7．to give 8．interesting 9．largely 10．in
【导语】本文是一篇说明文。文章讲述“中国速度”给我们带来的好处和坏处以及未来我们继续加速前进时应该如何平衡。
1．考查定语从句。句意：没有什么比中国的高铁系统更令人印象深刻的了，尤其是它的发展速度。设空处引导非限制性定语从句，修饰先行词the speed，关系代词在从句中做主语，故填which。
2．考查时态和主谓一致。句意：“中国速度”对国家意义重大。设空处为谓语，描述客观事实，应用一般现在时，主语是名词“China speed”，谓语用第三人称单数，故填means。
3．考查形容词。句意：在过去的30年里，中国在经济、科技和贸易等各个领域都取得了快速发展。设空处修饰名词areas，应用形容词various作定语，故填various。
4．考查名词的数。句意：我们看到许多高楼大厦几乎在一夜之间拔地而起，道路和高速公路连接着每一个角落。设空处为名词building，作宾语，前面有lots of修饰，应用复数形式，故填buildings。
5．考查冠词。句意：除了网上购物，移动支付在每个人的生活中扮演着越来越重要的角色。固定短语搭配play a role in，前面有increasingly important修饰，increasingly是发音以元音音素开头的单词，故填an。
6．考查语态。句意：然而，当我们享受“中国速度”的好处时，它带来的问题也不容忽视，比如空气污染和交通问题。此句中的can’t后面需要跟动词原形，但动词ignore与主语the problems之间是被动关系，因此需要用被动语态。故填be ignored。
7．考查不定式。句意：我们需要知道，我们的未来取决于我们今天所做的选择，因此，我们有责任给中国一个新的定义。此处为句型it be one’s duty to do sth.表示“做某事是某人的责任”，不定式作真正主语。故填to give。
8．考查形容词。句意：如果你仔细观察“速度”这个词，你可能会注意到每个字母都代表一些有趣的东西——社会、进步、经济、环境和发展。设空处修饰不定代词something，应用形容词interesting，作后置定语，表示“有趣的”，故填interesting。
9．考查副词。句意：我们社会的进步很大程度上取决于它们之间的平衡。设空处修饰动词depends，应用副词largely作状语，故填largely。
10．考查固定短语。句意：在中国继续加速前进的过程中，我们需要牢记这一点。短语keep in mind，意为“牢记”。故填in。
