A．that； whatB．what；/C．which； thatD．/； that

分析 你只能確定你現(xiàn)在有的東西；不能確定將來你或許會得到的東西．

解答 答案B．考查介詞后的賓語從句．of后面要加賓語，所填詞引導(dǎo)賓語從句，且在從句中作have的賓語，而that引導(dǎo)名詞性從句不擔(dān)當(dāng)任何成分，which意為"哪一個"，不符合題意．這里只能用what來引導(dǎo)．第二空所填詞要引導(dǎo)定語從句，先行詞是something，定語從句中引導(dǎo)詞that充當(dāng)get的賓語可以省略．故選B．

點(diǎn)評 考查從句的題，一定要分析主句和從句的句子成分．

4．Farming is moving indoors，where the sun never shines，where rainfall is irrelevant and where the climate is always right．The perfect crop field could be inside a windowless building with controlled light，temperature，wetness，air quality and nutrition．It could be in a New York high-rise or a complex in the Saudi desert．It may be an answer to the
The world already is having trouble feeding itself．Half the people on Earth live in cities，and nearly half of those-about 3 billion-are hungry or ill-fed．Food prices，currently increasing，arebuffetedby dryness．Hoods and the cost of energy required to plant，harvest and transport it．And prices will only get more unstable．Climate change makes long-term crop planning uncertain．Fanners in many parts of the world already are using water available to the last drop．And the world is getting more crowded：by mid-century，the global population will grow from 6.8 billion to 9 billion．
To feed so many people may require expanding farmland at the expense of forests and wilderness，or finding ways to completely increase crop output．
Gertjan Meeuws has taken the concept of a greenhouse a step further，growing vegetables and house plants in enclosed（封閉的）and regulated environments．In their research station，water flows into the pans when needed，and the temperature is kept constant．Lights go on and off，creating similar day and night，but according to the rhythm of the plant．
A building of 100 square meters and layers（層）of plants could provide a daily diet of 200 grams of fresh fruit and vegetables to the entire population of Den Bosch，about 140，000 people．Their idea isn't to grow foods that require much space，like corn or potatoes．
Here sunlight is not only unnecessary but can be harmful．Plants need only specific wavelengths of light to grow．Their growth rate is three times faster than under greenhouse conditions．They use about 90 percent less water than outdoors agriculture．And city fanning means producing food near the consumer，and there's no need to transport it long distances．
66．What can we mainly learn from Paragraph 2？C
A．The climate is worse and worse．
B．The city people live a hard life．
C．The world has difficulty feeding its people．
D．The world's population is increasing fast．
67．The underlined word"buffeted"in Paragraph 1 meansA．
A．badly affected        B．prevented      C．demanded      D．well achieved
68．Which of the following is true of the environments in the research station？C
A．The temperature is often changed．
B．Sunshine is in great need for plants．
C．Day and night depends on plants．
D．Air quality is controlled by plants．
69．It can be inferred from the text that Gertjan Meeuws's farmingB   
A．helps save sea water a lot                              
B．is highly adaptable
C．resembles greenhouse agriculture                        
D．suits the production of corn
70．What is the text mainly about？D
A．Development of indoor farming．                         
B．Great Revolution in farming．
C．Advantages of indoor farming．                          
D．Sunless，rainless indoor farming．
