本文主要介绍了黑洞的形成和科学家目前对它的了解等。11．objects [考查名词单复数。句意：它们是在很小的区域包含大量质量的物质。设空处位于系动词are后作表语，分析句子结构可知，空后是由that引导的定语从句，设空处为先行词，应用名词，且根据主语They和空后的contain可知，设空处应用复数形式，故填objects。]12．a [考查冠词。句意：当一颗恒星死亡时，它的组成物质会被挤压到一个越来越小的空间里。根据句意可知，此处泛指“一颗恒星”，应用不定冠词，且star的发音以辅音音素开头，故填a。]13．of [考查介词。句意见上一题解析。bemadeof为固定搭配，意为“由……制成”，故填of。]14．what [考查名词性从句。句意：最终它形成了所谓的恒星质量黑洞。设空处位于动词forms后，引导宾语从句，从句中缺少主语，且指代物，应用what引导，故填what。]\n15．is [考查动词的时态和主谓一致。句意：天文学家估计，这些相对较小的黑洞每秒都会有一个诞生。分析句子成分可知，设空处为that引导的宾语从句的谓语动词。由主句的谓语动词estimate可判断，从句是推测客观情况，应用一般现在时；且从句主语oneoftheserelativelysmallblackholes为第三人称单数概念，谓语动词应用第三人称单数形式，故填is。]16．bigger [考查形容词的比较等级。句意：顾名思义，超大质量黑洞要大得多。设空处位于系动词are后作表语，应用形容词；且根据句意和空前的much可知，此处应用比较级，故填bigger。]17．recently [考查词性转换。句意：但直到最近才有人真正看到过黑洞。结合句意可知，此处用作时间状语，表示“最近”，应用副词，故填recently。]18．called [考查非谓语动词。句意：这个环被称为吸积盘，散发热量和光。本句中已有谓语heatsup和givesoff，且与call之间无连词连接，故call应为非谓语形式作定语，修饰名词Thisring，且call和Thisring之间为逻辑上的被动关系，应用过去分词形式，故填called。]19．shared [考查动词的时态。句意：2019年初，科学家们分享了第一张黑洞照片。分析句子成分可知，设空处为句子的谓语动词；由时间状语Inearly2019可知，这是发生在过去的事情，应用一般过去时，故填shared。]20．using [考查非谓语动词。句意：他们用一个结合了世界各地八个天文台力量的虚拟望远镜拍摄了这张照片。本句主句中已有谓语动词made，且use与其之间无连接词，应用非谓语形式作状语，且use与其逻辑主语They之间为主动关系，应用现在分词形式，故填using。]
