13、le3.答案：invisible4.答案：straightforward5.答案：Fetch二、 6.答案：invited many aliens7.答案：screamed8.答案：was held9.答案：were very awesome三、答案：DECAG解析：根据上一句可以看出,研究者在实验中种植了10种不同的农作物,而由选项D中Tomatoes, peas, turnips, cabbages这些农作物种类可以判断该项符合上下文逻辑。 该空位于段落的开头,是该段的主题句。该段讲述了实验取得的一些进展,因此可以判断E项为正确答案。由后文的In the next round they f
14、lourished.可以判断C项符合上下文语境。Wamelink教授在此叙述了研究者没有吃这些农作物的原因。而A项正是原因之一,即土壤中含有重金属。由空格后文Wamelink教授给出的原因可知,G项中讲了这些农作物的种植条件,符合上下文的逻辑关系。四、答案：fascination ; a; what ; their ; was invented; giving; further ; Currently ; completed ;that 解析：考查词性转换。句意:自从人类历史开始以来,夜空一直是一个无穷无尽的魅力源泉。由设空处前面的介词of可以判断,此处应该填名词形式。因此填fascinati
15、on。 考查冠词。句意:很长一段时间,人们无法理解他们所看到的。while在此处是名词, for a long while意思为“很长一段时间”。考查名词性从句。what they could see在此处作understand的宾语,意思为“他们所能看到的东西”。考查代词。句意:古代的人们不知道星星是什么,他们用他们的想象力在天空中创造一个世界。根据设空处后的名词imaginations可以判断,此处应该填形容词性物主代词their。考查动词的时态和语态。句意:在第一个基于地球的望远镜被发明近400年后,哈勃太空望远镜被发射到轨道上,给了天文学家实际上是我们所有人第一个从地球以外拍摄到的我们的宇宙的叹为观止的美丽的图像。根据句意和上下文语境可知,此处应该用一般过去时的被动语态。考查非谓语动词。本句已有谓语,所以此处用非谓语动词。考查比较级。句意:为了更深入地观察宇宙,许多国家现在都在忙着建造更先进的望远镜。由设空处前面的even可以判断此处应该用比较级形式。考查副词。句意:目前,中国运行着世界上最大、最强的射电望远镜FAST望远镜已于2016年建成。副词放于句首,作状语,修饰后面整个句子。考查非谓语动词。过去分词在此处作定语,修饰前面的the FAST telescope。考查状语从句。由前面的So可以判断,此处填that,构成so.that.结构。
