英语周报答案2023-2024八年级上册1~29期

阅读下面短文并回答问题，然后将答案写到答题卡相应的位置上（请注意问题后的词数要求）。

[1]Oops! In your rush to get to school, you drop a piece of toast on the floor. Do you throw it away or decide it’s still OK to eat? If you’re like most people, you eat it. Maybe you follow the “5-second rule”, which claims foods are safe to eat，if you pick them up within 5 seconds of dropping them. But you might want to think again. Scientists now say that 5 seconds are all it takes for foods to become contaminated with enough bacteria to make you sick.

[2]Bacteria can cause many kinds of illnesses. Some kinds of bacteria can grow on food. If we eat foods on which these bacteria are growing, we can become sick. One of these food-borne bacteria is Salmonella. It makes 1.4 million people sick every year. Earlier this year, 370 people became sick after eating peanut butter that had been contaminated with Salmonella at the manufacturing factory. Salmonella are often found in raw eggs and chicken. Cooking kills these bacteria, which is why it is so important to cook eggs, chicken, and other foods carefully.

[3]Being a good housekeeper is another good way to prevent infection. If household surfaces aren’t washed thoroughly, they can support Salmonella for weeks. A team of scientists at Clemson University in South Carolina have tested the 5-second rule, using sandwich ingredients. First, they placed a known amount of Salmonella cells on three surfaces: wood, tile, and carpet. They then placed a slice of bread and a slice of bologna(博洛尼亚大红肠) on each surface for 5, 30, or 60 seconds. After just 5 seconds, both the bread and bologna picked up enough bacteria to make you sick.

[4]So forget the 5-second rule. If your toast lands on the floor, throw it away. Stick a fresh slice of bread in the toaster. And this time, be careful not to drop it!

英语周报答案2023-2024八年级上册1~29期试题答案

1.If you pick food up within 5 seconds of dropping them, they are safe to eat..

2.Because cooking kills bacteria.

3.Don’t eat food that has dropped on the floor. / Being a good housekeeper.

4.To find out how long it takes these bacteria to attach to food.

5.Negative.

【解析】

试题分析：文章大意：人们遵循的“五秒钟法则”即：“掉落的东西在5秒钟之内是不会沾染细菌的”.这一说法是正确的吗？美国南卡罗莱纳州的科学家做了一个实验，结果发现仅仅五秒钟,沾染到食物上的细菌足以致病，所以下次掉地上食物的时候，还是忘掉五秒钟法则吧。

1.细节理解题，根据文章第一段最后一句Maybe you follow the “5-second rule”, which claims foods are safe to eat，if you pick them up within 5 seconds of dropping them.可以归纳出答案。

2.细节理解题。根据文章第而段最后一句Cooking kills these bacteria, which is why it is so important to cook eggs, chicken, and other foods carefully.，从而可以得出答案。

3.细节理解题。根据文章最后一段So forget the 5-second rule. If your toast lands on the floor, throw it away. Stick a fresh slice of bread in the toaster. And this time, be careful not to drop it!可以归纳出答案。

4.细节理解题。从文章第三段But how long does it take these bacteria to pollute food? A team of scientists in South Carolina did an experiment.可知科学家实验的目的就是为了证明食物在多长时间内才会沾染到足以致病的细菌。

5.5】推理判断题。根据文章最后一段So forget the 5-second rule. If your toast drops on the floor, throw it away可知作者不赞同“五秒钟法则”。
