【分析】

1．考查介词短语。句意：不顾他们对我的指指点点，我将继续我的工作。regardless of“不顾；不管”，与句意相符。

2．考查if only的用法。if only“要是……就好了”；由时间状语yesterday来看，这是对过去所发生事情的虚拟，所以用过去完成时。

3．“get＋过去分词”构成被动语态。句意：逃犯一出现在火车站就被逮捕，并再度被送进监狱。

4．be of great significance“有重大意义；非常重要”。

5．考查时态。答句句意：在我们到达之前下了四天的雨，道路异常泥泞。表示在过去某一动作之前一直在进行，并有可能继续下去的动作，用过去完成进行时。

6．句意：假如我们得不到必要的设备，我们将不得不放弃这个实验。assuming表示“假定；设想”，引导条件状语从句，相当于if。具有相同用法的词还有supposing，regarding，given等。

7．句意：每天都有许多游客在这座可追溯到800年前的塔前拍照。短语date back to相当于date from，意为“追溯到；始于”。两者通常与过去的时间状语连用，但多用于一般现在时。

8．句意：许多年的*勤努力之后，她现在几乎能熟练地表演各种音乐。

9．考查非谓语动词。句意：校长匆忙赶往音乐厅，结果却发现主持人已经走了。第一空only后接不定式表示出乎意料的结果，意为“结果却……”；第二空可以用gone。

10．考查动词时态。句意表示母亲一上午都在做家务，现在仍在厨房做，故应用现在完成进行时表示从过去至今一直在持续的动作。

知识点：过去完成进行时
