Ⅳ.单项填空
1．Revise reported speech and practise vocabulary ________ global warming, natural disasters and ________ animals.
A．relating to; endangering
B．related to; endangering
C．relating to; endangered
D．related to; endangered
解析句意：复习间接引语并练习与全球变暖、自然灾害及濒危动物有关的单词。第一空relating to“与……有关”，现在分词短语作定语修饰vocabulary；第二空endangered“濒危的”，修饰animals。因animals与endanger 构成被动关系，故用其过去分词作定语。所以应选C项。
答案 C
2．________ the greenhouse effect，the Earth is warmed by gases ________ in the atmosphere.
A．Because; trapping B．Because; trapped
C．Because of；trapping D．Because of；trapped
解析because引导原因状语从句；because of＋名词或名词短语。由句式结构分析，第一空应用because of，故排除A、B两项；第二空gases与trap之间属被动关系，故应用过去分词trapped修饰gases，所以应选D项。
答案 D
3．Overfishing is harmful ________ the ecology of the sea.
A．for B．on C．to D．with
解析句意：捕捞过度对海洋生态是有害的。be harmful to sth对……有害。

4．So high ________ in several places that many homes are at risk from flooding.
A．the water level has risen
B．has the water level risen
C．the water level is risen
D．is the water level risen
解析句意：一些地方的水平面已经上升得如此高以致于许多住宅有被洪水淹没的危险。so＋adj./ad v.置于句首，句子要用部分倒装结构，所以排除A、C两项。rise属不及物动词，不能用被动形式，故应选B项。
答案 B
5．But what exactly is global warming and how is it relevant ________ our lives?
A．with B．to C．on D．of
解析考查固定短语。be relevant to...与……有关。
答案 C

C．in short D．in case
解析句意：全球变暖指的是地球温度平均增长，继而导致气候变化。in turn 转而；反过来；in return作为回报；in short简言之；in case以防万一。由句意知应选A项。
答案 A
7．Over the last 100 years, the global average temperature ________ by 1．
A．increases B．increased
C．will increase D．has increased
解析in/over the last...用作时间状语，句子往往用现在完成时，所以应选D 项。
答案 D
8．Recent reports warned that global warming will cause terrible climate changes ________ more frequent flooding, heat waves and droughts.
A．include B．includes
C．including D．included
解析句意：最近的报告警告说全球变暖会引起可怕的气候变化，包括更加频繁的洪水、热浪与干旱。including prep.意为“包括”，常位于所修饰的名词、代词前面。而included adj.意为“包括在内的”，常位于所修饰的名词、代词之后。所以应选C项。
答案 C
9．How can these disasters be ________ happening?
A．stopped B．kept
C．prevented D．stopped from
解析考查固定用法。stop/keep/prevent sb/sth from doing sth阻止某人/物干某事，其中from与stop或prevent连用时可以省略，但在被动语态中from一般不能省略。所以应选D项。
答案 D
10．________，give reasons for your answers.

阶段性测试(四)高二英语
荥阳高中2017-1018学年上学期实验班 阶段性测试（四）高二英语 第二部分阅读理解（共两节，满分40分） 第一节（共15小题；每小题2分，满分30分） 阅读下列短文，从每题所给的四个选项（A、B、C、D）中，选出最佳选项，并在答题卡上将该项涂黑。 A “I am not an American,” mark twain (1835-1910) once said, “I am the American.” He had good reason to say so. A Nobel winner in literature, US playwright Eugene O’ Neill called him “the father of American literature”. Twain is someone Americans are taught to love. Older relatives, English teachers and the media often praise him. But when you actually take the time to read the adventures of Tom Sawyer, which was first published 140 years ago, you find that his work is more wonderful than you could ever have imagined. The novel describes a young boy named Tom Sawyer growing up in a small town along the Mississippi River. He explores the countryside on a riverboat with his friends, falls in love with girls, starts secret clubs and searches for treasure. Twain’s idea of childhood is magical – a time of imagination, wonder and, of course, adventure. More importantly, through the eyes of Tom Sawyer, Twain cleverly makes fun of US culture. For example, Tom hates going to church, and Twain uses Tom to make fun of religion and its old traditions. “Often, the less there is to justify a traditional custom, the ha rder it is to get rid of it,” he writes in one chapter. Twain’s writing is full of these kinds of critical points about culture and politics. That’s why he is so loved in the US –he wasn’t afraid to state his opinions, and he did so clearly. For instance, Twain didn’t like US wars abroad. In 1900, after the US invaded the Philippines, Twain wrote in a newspaper article: “We do not intend to free, but to subjugate the people of the Philippines… We have gone there to conquer.” He also believed strongly in wo men’s right to vote in elections and gave a famous speech on the subject, called “Votes for Women”, in 1901.
高考数学一轮复习课时跟踪检测三十八空间几何体及表面积与体积含解析
课时跟踪检测（三十八） 空间几何体及表面积与体积 [A 级 保分题——准做快做达标] 1.关于空间几何体的结构特征，下列说法中不正确的是( ) A ．棱柱的侧棱长都相等 B ．棱锥的侧棱长都相等 C ．三棱台的上、下底面是相似三角形 D ．有的棱台的侧棱长都相等 解析：选B 根据棱锥的结构特征知，棱锥的侧棱长不一定都相等． 2．一个球的表面积为16π，那么这个球的体积为( ) A. 16 3 π B.323 π C ．16π D ．24π 解析：选B 设球的半径为R ，则由4πR 2 ＝16π，解得R ＝2，所以这个球的体积为43πR 3＝323 π. 3．如图所示，等腰△A ′B ′C ′是△ABC 的直观图，那么△ABC 是( ) A ．等腰三角形 B ．直角三角形 C ．等腰直角三角形 D ．钝角三角形 解析：选B 由题图知A ′C ′∥y ′轴，A ′B ′∥x ′轴，由斜二测画法知，在△ABC 中， AC ∥y 轴，AB ∥x 轴，∴AC ⊥AB .又因为A ′C ′＝A ′B ′，∴AC ＝2AB ≠AB ，∴△ABC 是直角 三角形． 4．下列说法中正确的是( ) A ．各个面都是三角形的几何体是三棱锥 B ．以三角形的一条边所在直线为旋转轴，其余两边旋转形成的曲面所围成的几何体叫圆锥 C ．棱锥的侧棱长与底面多边形的边长相等，则该棱锥可能是六棱锥 D ．圆锥的顶点与底面圆周上的任一点的连线都是母线 解析：选D 当一个几何体由具有相同的底面且顶点在底面两侧的两个三棱锥构成时，尽管各面都是三角形，但它不是三棱锥，故A 错误；若三角形不是直角三角形或是直角三角形但旋转轴不是直角边所在直线，所得几何体就不是圆锥，故B 错误；若六棱锥的所有棱都
