A【文章大意】 本文是一篇说明文,主要介绍了美国地质学家Thieler研制出一款应用程序以检测笛鸻栖息地的变化,从而帮助保护这种濒危动物。1.C推理判断题。根据第二段第二句可知,与气候变化有关的海平面上升和在它们的海滩栖息地进行的过度开发威胁到了这种物种。由此可推知,笛鸻的生存环境日益糟糕,故选C。2.D细节理解题。根据第二段第三句可知,Thieler研制iPlover旨在检测笛鸻栖息地的变化,故选D。3.D推理判断题。根据对第三段的整体理解可知,这个免费的应用程序发行后,科学家们的检测范围更广,并能更有效地收集相关数据,这些对于采取措施保护笛鸻是很有好处的。由此可推知,技术的进步会使笛鸻受益,故选D。4.A主旨大意题。根据对文章的整体理解可知,本文主要讲的是技术的进步给保护濒危动物带来的好处,故选A。B【文章大意】 本文是一篇记叙文,主要讲述了Fikiri Kiponda从一名会计到一位投身于拯救濒临灭绝的海龟的海洋自然资源保护者的故事。5.A细节理解题。根据文章第一段前两句可知,Fikiri Kiponda起初的梦想是成为一名会计,并实现了自己的梦想。但一次偶然的机会让他又成为一名海洋自然资源保护者。故选A。6.D推理判断题。根据第四段第二句可知,为了容纳更多的游客,酒店越来越多,海龟筑巢的滩涂越来越少,故推断这是对海龟的主要威胁。故选D。7.B推理判断题。根据第二段中的内容可知,他离开会计工作并全身心地投入到海龟的世界,从而推断出他是一位具有工作热情并富有同情心的人。故选B。8.A主旨大意题。根据对全文的理解可知,本文主要讲述了Fikiri Kiponda从一名会计到一位投身于拯救濒临灭绝的海龟的海洋自然资源保护者的故事,故选A。.【文章大意】 本文是一篇说明文,主要对海洋资源枯竭的原因进行了分析。1.gone考查非谓语动词。gone在此处是过去分词作形容词,意为“不见,消失”,在语境中作表语,和句子谓语are之间没有连词。注意:此处非被动的含义。2.themselves考查代词。与句子主语many species呼应可知,此处用反身代词的复数形式,表示“自我替换,自我循环”的含义。3.in考查介词。be/become interested in意为“对感兴趣”,符合语境,故用介词in。4.catching考查非谓语动词。固定词组搭配begin doing sth意为“开始做某事”,动名词作宾语,与语境中selling呼应。5.greatly考查副词。修饰动词的词一般为副词,故用副词greatly修饰动词reduce,在句子中作状语。6.but考查连词。根据语境可知,上下句表示逻辑上的转折关系,故用连词but。7.which考查定语从句。which引导非限制性定语从句,在从句中作主语,修饰先行词small fish。8.to eat考查非谓语动词。enoughto do sth意为“足够以至于可以做某事”,不定式作状语。9.are考查主谓一致。与语境中they呼应可知,此处表示复数概念,故谓语用复数are的形式。10.difficulties考查词性转换。根据语境所列举的各种困难可知,此处用名词的复数形式,即difficulties。.Among the four seasons in a year, summer is my favourite, that makes me free, excited and energy. which energeticWhen summer vacation came every year, we can do all that we cant do during our school time, go shopping comes goingwith friends, swimming in warm water and even hiking and camping in the deep valleys. These activities lead me to enjoy full free. We can find us in an exciting world every day, with the sun shining bright, trees growing freedom brightlybetter and flowers coming out of with all kinds of colours. Summer makes me full of energy and we feel I have the Istrength to do the most difficult things in my life. I like summer better, and what about you? best
