1.------------native to European,the daisy has now spread throughout most of the North America. A. Although B. If it were C. In spite of D. That it is key:A Reason: Although :conj. 连接2个句子。b2个句子的主语一致，谓语不一致！c介词短语，不能连接2个句子。d that 后面是完整的句子，那that应该是形式主语，而这里显然不是。例子: That Taiwan is a part of China is a definite fact. a although 后面省略了it is
2.Commercial expansion from city to suburb has affected the way people in the United States------- A. living and working B. they live and work C. live and work D. to live and work key:c Reason: d 从语法上也讲得通。 c 应该是在way的后面省略了that（在后面的句子力作宾语）。
3.Today--------little fossil ivory remains comes from Alaska. A. what B. which C. there is D. where key:A Reason:和1差不多了。what 和that 一样，引导主语从句，用what 是因它有实际意思.remian是谓语动词。b,which要在句子里作主语或者宾语.c, 使得整个句子有2各谓语is和comes. d, where要做壮语。4各选项里只有what可以引导主语从句
4:-------vastness of the Grand Canyon,it is difficult to capture it in a single photograph. A:while the B:The C:For the D:Because of the key 为什么不能选C? Reason: 有because of the 这么标准的答案，当然不选c。for 表示原因不在句首，而且，for 后面跟表示目的的动名词多一些。
5.The daytime-------bright because the Earth’s atmosphere scatters sunlight. A. while sky is B. has a sky C. sky is D. for the sky key:C Reason: daytime这里是noun用作adj,because 连接2个独立的句子。你选什么？
6.First designated in 1970 Earth Day has become an annual international event----------concerns about environmental issues such as pollution. A. dedicated to raising B. dedicated raising C. dedicated to raise D. that dedicates to raising key:A 为什么选A啊，D有什么不对？
Reason: dedicate 和event之间是被动的关系，event本身不能dedicate。d相当于dedicating to rasing.
ppview test1-1 17. The leopard seal is the only pinniped____ preys on penguins and the seals. 选对了，只是review的时候想不通of which it normally为什么不对？the pinniped表示一类。一时想不到prep.+which的句型了 7.instrument,equipment,furniture 都不是可数名词吧?
