8.此题为时态考查。通过上下句可知,文章以过去时为时间基调。因此,starte采用过去时started.

拓展:(2014年新课标I) The river was so polluted that it(62)(actua)caught fire and burned.

基本结构:主语+have/has+动词的过去分词(p.p)

b,定语从句所修饰的词叫先行词;定语从句一般用关系代词或关系副词来引导,关系词放在先行词与定语从句之间起连接作用,同时又作从句中的一个成分。

Diets have changed in china-and so too has its top crop. Since 2011, the country ____(grow)more corn than rice。 Corn production has jumped nearly 125 percent over____past 25 years, while rice has increased only 7percent.

1. has grown 2. the 3. actually 4. to improve 5. than 6. pollution 7. global 8. started 9.that/which 10.feeding。

拓展:非谓语动词包含四种形式,即不定式、动名词、现在分词和过去分词。

拓展:a,在复合句中,修饰某一名词或代词的从句叫定语从句。

6.此题考点为构词法。语境需要名词形式。pollute是“污染;玷污;败坏”的意思,变成名词pollution“污染”。

2.冠词的考察。in/over the past/last few years“在过去的几年里”, 都是现在完成时态的标志。

不定式:a,基本形式:to do(表示主动,并且一般表示将来);b,被动式:to be done(表示被动,并且一般表示将来);c,进行式:to be doing (表示主动和进行);d,完成时:to have done(表示主动和完成);e,完成被动式:to have been done(表示被动和完成);f,完成进行时:g,to have been doing (表示主动和完成进行)。

4.此题考点是非谓语动词,动词在句子中除做谓语外的其它语法成分叫非谓语或非限定动词。本题中所给动词(improve)作目的状语,因此用不定式(to improve)。对于非谓动词考查比较难,必须考虑非谓语动词的具体语体与语态问题。

拓展:现在完成时的用于:a,过去发生的动作对现在造成的影响。b,过去的动作或状态持续到现在并且可能继续下去。c,现在完成时表示将来。

(形容词变副词) actually

拓展:a,介词不能单独使用,必须带上宾语构成介词短语,或依附在不及物动词后面使用。介词短语可以在句子中充当状语,定语,表语和宾语补,本题是介词短语作比较状语。b,than用作介词时意思为“与…相比”,用于名词或代词前表示比较关系,也可用于在度量衡方面的比较。

3.此题考点为构词法。副词主要用来修饰动词,形容词,副词或其他结构。actual为形容词,actually为副词。

10.此题考查了现在分词作状语。句中用feed的非谓语动词feeding,在句中作状语,feeding的逻辑主语是句子的主语。

9.此题考点为定语从句。本句中“a soil-testing program”为先行词,它在从句中做主语因此既可以填which也可以填that 。

阅读下面短文,在空白处填入1个适当的单词或括号内单词的正确形式。

5.此题考点为介词,根据句义和标志“less”,此题填介词“than”。

1.谓语动词的时态考查。从上下文的语境,以及 “Since 2011“作为时间标志,可以判定此句用现在完成时。

According to the World Bank, China accounts for about 30 percent of total ____(globe)fertilizer consumption. The Chinese Ministry of Agriculture finds that between2005-when the government ____ (start) a soil-testing program ____ gives specific fertilizer recommendations to farmers- and 2011, fertilizer use dropped by 7.7million tons. That prevented the emission(排放) of 51.8 million tons of carbon dioxide.China's approach to protecting its environment while ____(feed) its citizens“offers useful lessons for agriculture and food policymakers worldwide,” says the bank's Juergen Voegele.

7.此题考点为构词法。语境需要形容词形式。globe是“地球;地球仪;球体”的意思,变成形容词global“全球的;总体的;球形的”。
