(A)你知道转基因食物吗？阅读短文,判断下列句子正(T)误(F)。(10分)
It is hard to be farmers. Cold weather can kill your plants. Bugs can eat your plants. Weeds(杂草) can hurt your plants. Your plants may need more rain than they get. Fruit and vegetables can go bad before you sell them. Some people say farmers can solve all these problems with GM food.
What is GM food? All living things have DNA. DNA tells how living things grow. These days, people can change DNA that tells how food grows. When people change DNA of the food, it is called GM food.
Some GM food can grow in cold weather. GM food can stop bugs from eating it. GM fruit and vegetables can stay longer. One day, GM food may be able to grow in dry land in Africa. It will feed people who do not have much food.
But there is a lot we do not know about GM food. Will GM companies help poor people grow food? Or do GM companies just want to get rich? Does GM food kill bugs we need? Does GM food make birds sick? Does GM food make people sick? We do not know.
( )1. The passage lists six reasons why farmers feel hard.
( )2. 逻辑关系 We get GM food by changing food's DNA.
( )3. Nowadays, we can grow GM food in dry land in Africa.
( )4. 观点态度 The writer wants to tell people to learn more about GM food.

知识点拨
“thanks to”是一个常见的英文短语，通常被翻译成“由于”“多亏”或“因为”。它用来表达某件事的发生是由于某个特定原因，这个原因可能是正面或负面的。然而，尽管“thanks to”看似与“感谢”有关，但它并非总是表达感谢之意。
当“thanks to”后面的原因是正面的时，它确实可以表达感谢，例如：Thanks to your help，I finished the project on time. 多亏你的帮忙，我准时完成了方案。
然而，当“thanks to”后面的原因是负面的时，它就带有一点讽刺的语气，表示某件事发生是因为一个不理想的因素，例如：Thanks to the heavy rain，our picnic was canceled. 由于大雨，我们的野餐被取消了。
因此，在使用“thanks to”时，我们需要仔细考虑后面的原因是正面的还是负面的，以避免产生误解。如果我们想表达感谢，可以使用更直接的表达方式，例如“Thank you for...”。
3. B 解析：根据原文第三个方框“... can improve your sleep. It can control the temperature，light and even air quality in your bedroom. And it can record your sleep cycles.”可知，智能闹钟能够提升你的睡眠质量；它可以控制温度、光线甚至是卧室里的空气质量；它也可以记录你的睡眠周期。文中并没有提到智能闹钟能控制体重，故选 B。
4. A 解析：根据原文第四个方框“The lack of vitamin A can cause blindness.”可知，缺乏维生素 A 会导致失明，故推测如果一个孩子视力不好，他或她可能缺乏维生素 A，故选 A。
5. A 解析：根据文章第一行“Inventions make the world better，smarter and a little more fun.”及下文内容可知，本篇文章介绍了四种发明，所以可能会在报纸上看到这篇文章，故选 A。
2. C 解析：根据原文第二个方框“Now，thanks to an American company，the shoe dream comes true.”可知是美国的公司，故选 C。
