24、spite recent advancements in 3D food printing, the industry has many challenges to overcome. Currently, most ingredients must be changed to a paste(糊状物) before a printer can use them, and the printing process is quite timeconsuming, because ingredients interact with each other in very complex ways.
25、On top of that, most of the 3D food printers now are restricted to dry ingredients, because meat and milk products may easily go bad.

37、时间是特指的，故应该用定冠词the。3actually考查副词。空格处修饰is，故应将形容词actual写成副词actually。4to improve考查不定式。句中已经出现了谓语动词，且空之前没有连词，所以考虑非谓语；根据句意可知空格处表目的，所以应用不定式to improve。5than考查比较级的固定搭配。根据语意可知此处需要填比较级的固定搭配，再根据前面less可知，此处应为less than固定搭配。6pollution考查动词变名词。decreased pollution 动宾搭配，所以此处需要填名词作宾语。7global考查名词变形容词，意思是“全球的，总体的”。8started考查动词的时态，一般过去时。项目开始的时间是2005，所以用一般过去时。9which/that考查定语从句，先行词是program, 在定语从句中担当主语的成分，用which或that。10feeding考查非谓语，While feeding its citizens是时间状语从句，while it is feeding its citizens的省略。又可理解为此处的“feed”与主语China为逻辑上的主谓关系，故填现在分词形式。
