芬蘭科學(xué)家稱，在未來(lái)十年內(nèi)，這種“用空氣制成的”蛋白質(zhì)將在價(jià)格上與大豆競(jìng)爭(zhēng)。這種蛋白質(zhì)是由土壤細(xì)菌制成的，這種細(xì)菌以電解水中的氫為食。

With farming blamed for contributing to many environmental problems, there's been increasing investment in novel foods grown from bacteria. A study last year concluded that protein from microbes was several times more efficient than soya in terms of land use and required just a tenth of the water.

由于務(wù)農(nóng)活動(dòng)被認(rèn)為是造成許多環(huán)境問(wèn)題的原因，人們對(duì)由細(xì)菌制成的新型食物的投資不斷增加。去年的一項(xiàng)研究得出結(jié)論：制造微生物蛋白質(zhì)的土地使用效率要比種植大豆高出數(shù)倍，而且用水量?jī)H需其十分之一。

The bacteria food, Solein, can be used as a substitute for soya in a host of foods, such as pies, ice creams, breads and cakes. It can also feed livestock without harming rainforests in the way new soya plantations often do.

這個(gè)名為 “Solein” 的細(xì)菌食品可作為許多食物中大豆的替代品，如餡餅、冰淇淋、面包和蛋糕。它還可以在不破壞熱帶雨林的情況下用來(lái)喂養(yǎng)牲畜，在這一點(diǎn)上它與多數(shù)新型大豆種植園的做法相同。

Academics say it won't be a cure for all the problems associated with farming, but it will help if people are willing to eat it.

學(xué)者們表示，這不會(huì)完全解決與務(wù)農(nóng)相關(guān)的所有問(wèn)題，但如果人們?cè)敢獬运?，則將有一些幫助。

閱讀理解：請(qǐng)?jiān)谧x完上文后，回答下列問(wèn)題。

1. How is growing protein from microbes more efficient than growing soya?

2. Why has there been increasing investment in foods grown from bacteria?

3. How much damage is there to the rainforest when livestock are fed bacteria-grown foods?

4. True or false? Soleine can be eaten as a substitute for things like ice cream and cakes.

答案

1. How is growing protein from microbes more efficient than growing soya?
Growing protein from microbes was several times more efficient than soya in terms of land use and required just a tenth of the water.

2. Why has there been increasing investment in foods grown from bacteria?
Farming has been blamed for contributing to many environmental problems. As a result, there's been increasing investment in novel foods grown from bacteria.

3. How much damage is there to the rainforest when livestock are fed bacteria-grown foods?
According to the report, none: Bacteria food can feed livestock without harming rainforests in the way new soya plantations often do.

4. True or false? Soleine can be eaten as a substitute for things like ice cream and cakes.
False. The bacteria food, Soleine, can be used as a substitute for soya in a host of foods, such as pies, ice creams, breads and cakes.
