嗨，亲爱的们，今天重庆新航道的小编要给大家分享的是雅思话题分享，讨论转基因农作物的优势与劣势，下面我们就一起来看看吧。
Genetically modified organisms, or GMOs, are plants that have had their genes manipulated. They give the crops new characteristics, like insect resistance, larger yields, and faster growing traits.
转基因生物是指基因被处理过的植物。它们赋予作物新的特性，例如抗虫性，更高的产量和更快的生长特性。
语言解析:
1. modify: 修改, change something slightly in order to improve it. 以后不要总是用change了。
2. manipulate: 操控，对前面modify的一个替换。
3. trait: 特征，对characteristic的替换表达。
At least 26 countries grow genetically modified crops, while 19 of 28 European Union nations have partially or fully banned GMOs because they believe that sufficient research on the long-term effects has not been conducted.
至少有26个国家种植转基因作物，而28个欧盟国家中有19个国家部分或全部禁止了转基因生物，因为他们认为尚未就长期影响进行充分的研究。
语言解析:
4. conduct research: 开展研究，conduct 可以替换为carry out; do; undertake
01 Advantages
Population growth, climate change, over-farming, and water shortages all contribute to food scarcity. GMOs can help address those problems with genetic engineering to improve crop yields and help farmers grow food in drought regions or on depleted soil, therebylowering food prices, feeding more people and alleviating world hunger.
人口增长，气候变化，过度耕作和水资源短缺均导致粮食短缺。转基因生物可以帮助解决这些问题，通过基因工程的技术提高作物产量，并帮助农民在干旱地区或贫瘠的土地上种植粮食，从而降低粮食价格，养活更多人并减轻世界饥荒。
语言解析:
5. lower food prices: 降低价格; lower可以替换成cut; reduce; push down。相反的提高价格是increase; raise; push up。
6. alleviate hunger: 减轻饥荒。把问题减轻，常用的几个词是alleviate; relieve 和 mitigate.
One of the modifications made to the crops is an added resistance to disease that would normally kill off the crops. This means that growing GMO crops leads to reduced use of pesticides which pollute the ground soil. Besides, many GMOs require a smaller amount of chemical fertilizers tothrive, so the impact on the environment is further lessened.
对农作物的改良之一是增加了对通常会杀死农作物的疾病的抵抗力。这意味着种植转基因作物导致农药使用量的减少，这些农药会污染土壤。此外，许多转基因生物需要少量的化肥就能茁壮成长，因此对环境的影响进一步减轻。
语言解析:
7.lessen: 减少，降低，reduce的最常用替换词; lessen the risk; lessen the pain; less the possibility
Along with resistance to insects and disease, the genes of the crops can also be altered tohave a better flavor and increased nutritional value.
除了对昆虫和疾病的抵抗力之外，还可以改变农作物的基因，使其具有更好的风味和更高的营养价值。
语言解析:
8. alter: 改变，change的替换词，对前面modify的替换
02Disadvantages
There has been very little testing and research done on genetically modified foods and the long-term effects have not been discovered yet. This makes many people feel uneasy at the high use of these foods. Ever since the introduction of GMO foods, the amount of childhood food allergies has risen significantly.
对转基因食品的测试和研究很少，长期影响尚未发现。这使许多人对这些食物的大量使用感到不安。自从引入转基因食品以来，儿童期食物过敏症的数量已大大增加。
语言解析:
9. introduction: 新采用或初次投入使用
10. allergy: 过敏症
The crops that have been genetically modified have antibiotic properties put into them in order to make them immune to certain diseases. When consumers eat these foods these properties are left in their body and can make many antibiotics less effective.
经过转基因的农作物具有抗生素特性，以使其对某些疾病具有免疫力。当消费者吃这些食物时，这些特性会留在他们的体内，使许多抗生素的功效降低。
