1The weather in Texas may have cooled since the recent extreme heat, but the temperature will be high at the State Board of Education meeting in Austin this month as officials debate how climate change is taught in Texas schools.
主干主语：the weather / the temperature；谓语：may have cooled / will be；表语：high
结构并列复合句：前一分句含 since 引导的时间状语；but 连接转折。后一分句中 as 引导时间状语从句，其内嵌 how 引导的宾语从句作 debate 的宾语。temperature will be high 为双关，既指气温也指会议气氛紧张。
译文得克萨斯的天气或许已从近日的极端高温中凉快下来，但本月奥斯汀州教育委员会会议上的“温度”仍会很高，因为官员们将辩论气候变化该如何在得州学校讲授。
考点as 引导时间状语从句，常表“当……时/随着”，勿一律译成“因为” · how 引导的名词性从句作 debate 的宾语
2A study last year by the National Center for Science Education, a non-profit group of scientists and teachers, looking at how state public schools across the country address climate change in science classes, gave barely half of US states a grade B+ or higher.
主干主语：a study；谓语：gave；间接宾语：barely half of US states；直接宾语：a grade B+ or higher
结构主干为 A study gave...。by... 介词短语作后置定语；a non-profit group... 为同位语；looking at... 为现在分词短语作定语，其内含 how 引导的宾语从句。插入成分多，易把 looking 误当成谓语。
译文去年，由科学家与教师组成的非营利组织“国家科学教育中心”开展的一项研究，考察了全美各州公立学校在科学课上如何讲授气候变化，结果仅有勉强一半的州获得 B+ 或更高评级。
考点give sb. a grade 双宾语结构 · 分词短语 looking at 修饰 study，不是独立谓语
3Among the 10 worst performers were some of the most populous states, including Texas, which was given the lowest grade (F) and has a disproportionate influence because its textbooks are widely sold elsewhere.
主干主语：some of the most populous states；谓语：were（倒装）；表语：among the 10 worst performers
结构地点状语 among... 前置引起完全倒装。including Texas 作补充说明；which 引导非限制性定语从句，内含并列谓语 was given 与 has；because 引导原因状语从句。
译文表现最差的十个州里，就有若干人口大州，包括得克萨斯：该州被评为最低等（F），却因教材销往外州而影响力不成比例地大。
考点Among... were... 完全倒装 · which 定语从句中并列谓语 + because 原因从句
4Another issue is that while climate change is well integrated into some subjects and at some ages—such as earth and space sciences in high schools—it is not as well represented in curricula for younger children and in subjects that are more widely taught, such as biology and chemistry.
主干主语：another issue；谓语：is；表语：that 从句（主句 it is not as well represented）
结构that 引导表语从句。从句内 while 引导让步状语从句；破折号插入举例；主句用 not as well... 比较结构；that are more widely taught 为定语从句修饰 subjects。
译文另一问题是：尽管气候变化在某些学科、某些学段——例如高中的地球与空间科学——已融入得较好，但在低龄儿童课程以及更普遍开设的学科（如生物、化学）中，它的体现远没有那么充分。
考点while 此处表让步而非时间 · not as well represented 比较结构省略 as in some subjects
5Branch points out that, even if a growing number of official guidelines and textbooks reflect scientific consensus on climate change, unofficial educational materials that convey more slanted perspectives are being distributed to teachers.
主干主语：Branch；谓语：points out；宾语：that 从句（主语：unofficial educational materials；谓语：are being distributed）
结构that 宾语从句中，even if 引导让步状语从句；主句为被动进行时 are being distributed；that convey... 为定语从句修饰 materials。even if 与主句被逗号隔开，层次需分清。
译文布兰奇指出，即便越来越多的官方指南和教材已体现关于气候变化的科学共识，向教师分发的非官方教辅材料仍在传达更为偏颇的观点。
考点even if 让步状语从句 · that convey... 限制性定语从句 + 被动进行时
