70. Space (space) vegetables
解析
文章大意:本文主要讲了人们需要了解一些关于太空蔬菜的事实。
66.     (1). which/that    (2). For   【解析】分析“Space vegetables are grown from seeds (A)_____ are carefully chosen.”的句子结构可知此处是seeds作先行词的定语从句,先行词指物,且在从句中作主语,用关系词which或that;“____ example”后的句子是举例说明太空蔬菜比我们平时吃的蔬菜更好,此处用for example表示“例如”,for的首字母大写。故答案为which/that; For。
67. seeds (from space)  【解析】根据画线词所在语境“After seeds are brought back from space, (C)they are tested to make sure that the vegetables they grow will be safe to eat.”可知被测试的是从太空带回了的种子,they指代上文中的来自太空的seeds。故答案为seeds (from space)。
68.     (1). be    (2). harmful  【解析】考查同义句转换。结合题干中“to your health”可推出原句中be bad for要替换为近义短语be harmful to,表示“对……有害”。故答案为be harmful。
69.     (1). bigger    (2). healthier 【解析】根据第1段中“When they are brought back to the earth, these seeds produce vegetables that are bigger, healthier and more nutritious than normal vegetables.”可知太空蔬菜比普通蔬菜更大、更健康、更有营养。故答案为bigger; healthier。
70. Space (space) vegetables【解析】结合全文内容可知本文主要讲的是太空蔬菜的一些相关事实,能说明本文中心大意的短语是“space vegetables”。故答案为Space (space) vegetables。
