五、词与短语填空(共 5 小题,每小题 2 分,满分 10 分)
large / products / small / makes up / cost / focusing / looking
There are many types of dairy alternatives(乳制品替代品) on the market today, often made from things like nuts and soybeans.
But have you heard someone is now making butter from air?
Why butter?
A 2021 study showed that food production about 35% of the world's greenhouse gas emissions(排放) — and some scientists think that about 7% of greenhouse gas emissions are just from producing fat.
Some scientists are on butter to start with partly because its high price point makes it easier to compete on . But other scientists hope to develop other like milk, ice cream, cheese — even meat.
"Man - made fats may seem strange at first, but they can greatly reduce our carbon footprint and their potential(潜力) is very ." Gates once wrote.
66. 67. 68. 69. 70.

66. makes up 67. focusing 68. cost 69. products
70. large

【解析】
66. 此处需表达“占（比例）”，主语food production是第三人称单数，结合语境填makes up，意为“构成，占比”。
67. 固定搭配focus on表示“专注于”，句中已有are，用现在分词focusing构成现在进行时，符合句意。
68. 根据前文“its high price point”可知，这里指在成本上竞争更有优势，填cost（成本）。
69. 后文列举的milk, ice cream等都属于产品，other后接可数名词复数，故填products。
70. 此处描述人造脂肪的潜力，large表示“大的”，符合“潜力很大”的语境。
【答案】
66. makes up
67. focusing
68. cost
69. products
70. large
