【答案】connected；frequently；has reached；as；zones；what；be spent；to put；themselves；(more) successful

【解析】【分析】这是一篇议论文。文章介绍了微信给人们带来方便的同时，也存在着一些弊端。

（1）句意：随着现代技术的发展，人们可以很容易地与家人和朋友保持联系，不管他们相距多远。系动词stay后，用形容词connected“有联系的”，stay connected with“与……保持联系”。故填connected。

（2）句意：微信是中国最常用的交流方式之一。修饰形容词used，用副词。故填frequently。

（3）句意：据报道，到目前为止，微信的用户数量已经超过11亿。so far做时间状语时，应使用现在完成时，the number of做主语时，谓语动词使用第三人称单数形式。故填has reached。

（4）句意：一旦加入微信，人们可以发现越来越多的人开始添加他们作为朋友。根据句意，此处使用介词as表示“作为”。故填as。

（5）句意：他们在交流时不需要考虑时区。“时区”是复数意义，前面没有冠词，应用名词复数形式。故填zones。

（6）句意：人们可以很方便地通过微信立即更新他们正在做的事情。____6____ they are doing by WeChat是一个宾语从句，引导词在从句中做doing宾语，表“正在做的事情”，应使用what引导。故填what。

（7）句意：然而，沉迷于微信将会剥夺人们原本应该花在更重要事情上的时间。“时间”和“花费”之间是被动关系，用被动语态，由空前should可知，此处be动词使用原形。故填be spent。

（8）句意：而许多所谓的朋友根本不是真正的朋友，他们只是想在朋友圈里放广告或卖

东西。固定短语：want to do sth. “想要做某事”。故填to put。

（9）句意：此外，在微信上的人更有可能自己与他人比较，这将使他们当发现一些人似乎更成功，感觉难过。文中表示“人们自己与他人比较”，用反身代词。故填themselves。（10）句意：此外，在微信上的人更有可能自己与他人比较，这将使他们当发现一些人似乎更成功，感觉难过。be后，用形容词作表语，根据语境此处可以使用形容词原级或比较级。故填more successful。

【点评】考查语法填空，考查词汇在语篇中的应用能力。对于给出提示词的空，要注意提示词在句子中充当的成分，若充当谓语，注意动词的时态和语态；若充当非谓语，注意给出单词与被修饰词的主被动关系；若给出形容词，名词，代词等，注意根据句子结构进行变形。若没给出提示词，注意分析句子成分，填出合适的词。
