3．(2018·浙江卷阅读)The easiest way __________________(accmplish) this is t make sure yu cnduct yurself as a gd neighbr shuld.解析：句意：实现这一点的最简单的方法是确保你的表现和好邻居应该的表现一样。4．__________ he culd call the plice, the thieves had run away with the suitcase，leaving him shcked and helpless.解析：考查连词。句意：他还没来得及打电话报警，小偷已经带着手提箱逃跑了，这使他感到震惊与无助。根据句意可知，befre“在……发生以前”正确。
t accmplish　
5．I'd appreciate ______ if yu culd cme and help me nce mre and I always appreciate ___________(help) me with my English in the past.解析：考查appreciate的用法。I'd appreciate it if...为固定结构，意为“假如……，我将不胜感激。”；appreciate后可以跟动名词作宾语。6．With his attentin _________(fix) n his mbile phne, he didn't ntice his headteacher's appearance.解析：考查with的复合结构。句意：他只顾看自己的手机，没有注意到班主任老师的出现。“with＋名词/代词＋分词/形容词/副词/介词短语”为with的复合结构，在句子中作状语，表行为方式、伴随、时间等。固定搭配：fix ne's attentin n sth.“集中注意力于……”，为固定搭配，本题中attentin与fix构成动宾关系，故应用过去分词。
7．Ht ______________ the night air was, we slept deeply because we were s tired after the lng jurney.解析：句意：虽然晚上很热，但因长途旅行之后很累，我们睡得很沉。as/thugh“虽然”，引导让步状语从句时，要将表语、状语或动词原形置于句首。8．There are several ways ________ we can crss the river withut the help f lcal villagers.解析：考查定语从句。句意：在没有当地村民的帮助下，我们有几种过河的方法。分析句子结构可知，这是一个定语从句，that引导定语从句，在从句中作方式状语，修饰先行词ways。注：在定语从句中，当先行词是way时并在从句中作状语，定语从句的引导词可用in which，that或省略关系词。
9．It's standard practice fr a cmpany like this ne______________(emply) a security fficer.解析：考查非谓语动词。句意：对像这样的一个公司来说，雇用一个安全人员是常规做法。首先分析句子结构和句意可知题干中主系表结构已经很完整了，而且a cmpany与emply之间构成主动关系。只是it所指代的内容还不够明确和详细，所以it是形式主语，真正的主语是后面的不定式短语t emply a security fficer。a cmpany like this ne 是emply的逻辑主语。10．(2017·北京)T d CPR, yu press n the sick persn's chest ______ that bld mves thrugh the bdy and takes xygen t rgans.解析：句意：要进行心肺复苏，你要按压病人的胸膛，这样血液在身体里流动，把氧气带到各个器官。

I'll tell Dad there's nthing serius.解析：某些不可数名词，如pity，shame, success，relief等，在表示具体某一次时，可加a，但无复数。
