易错题解析：
Paragraph 1: Sometime after midnight on February 8,1969, a large, bright meteor entered Earth's atmosphere and broke into thousands of pieces, plummeted to the ground, and scattered over an area 50 miles long and 10 miles wide in the state of Chihuahua in Mexico. The first meteorite from this fall was found in the village of Pueblito de Allende. Altogether, roughly two tons of meteorite fragments were recovered, all of which bear the name Allende for the location of the first discovery.
2. Which of the following can be inferred from paragraph 1 about the large meteor that entered Earths atmosphere on February 8, 1969?
O It was almost ten miles wide.
O It was the biggest meteor ever to hit Mexico.
O It weighed more than two tons.
O It broke into more pieces than most meteors do.
题型：推论题。答案是(C)
解析：以时间做关键词定位至第一句，事实上整个第一段都是在描述1969年2月8号进入地球大气层的那颗大陨石，所以可以先浏览整断然后再判断选项。原文第二句说收集了大致两吨的碎片，碎片都有两吨了，那meteor自然不止两吨，所以C正确。
A选项定位原文“···and scattered over an area 50 miles long and 10 miles wide in the state of Chihuahua in Mexico.”说的是meteor的碎片掉落的区域的宽度是10英里，并不代表meteor有10米宽，所以A错;B选项的biggest太绝对，并且在原文中没有相关信息可以推断，所以错误;D选项的more pieces，原文将1962年2月8日进入地球的陨石和其他陨石坠落情况进行比较，所以不选。
易错选项：(A)。
14. Directions: An introductory sentence for a brief summary of the passage is provided below. Complete the summary by selecting the THREE answer choices that express the most important ideas in the passage. Some sentences do not belong in the summary because they express ideas that are not presented in the passage or are minor ideas in the passage. This question is worth 2 points.
Studies of the Allende meteorite provided information about the composition of chondritic meteorites and their possible origin.
Answer Choices
O When Allende entered Earth's atmosphere, it broke into thousands of pieces called chondrites because they look like glassy, black seeds.
O The mineral content of chondrules suggests that they were probably formed in isolated regions of the nebula that remained much hotter than the rest.
O Chondrules are tiny, millimeter-sized drops of silicate materials that probably formed when lumps of nebular dust were fused at extremely high temperatures and then quickly cooled.
O Irregularly shaped inclusions in Allende are composed of minerals that are resistant to melting and are believed to be the earliest minerals to have condensed out of the nebula.
O The matrix that holds the chondrules and inclusions together in Allende consists mainly of grains of nebular dust that were trapped inside the meteor before they could be melted.
Except for being depleted in volatile elements, chondritic meteorites are probably very similar in composition to the matter from which planets were assembled.
题型：文章小结题。答案是(C D F)
原文思路：
第1段 阿伦德陨星坠落的时间地点
第2段 阿伦德陨星的组成成分
第3段 阿伦德陨星属于球粒陨石
第4段 阿伦德陨星的成分是耐高温的内含物
第5段 阿伦德陨星里的陨石球粒和内含物是由球粒陨石基质结合到一起的
第6段 各种各样的组分被凝聚到一起形成了球粒陨石，就像与太阳具有很多相似化学组分的阿伦德陨星。
解析：C选项对应原文第三段，正确;D选项对应原文第四段的开头两句，Equally perplexing …… chondrules. They are …… elements in the nebula. 正确;F选项对应原文最后一段，正确。
