Most plastic is not biodegradable (可生物降解的), and a lot of it ends up in the sea. How big is the problem? There are billions of bits of plastic in the world’s sea! Every ocean and every beach has plastic, from large objects to small pieces called microplastics. Tons of plastic go into the sea every year. Increasing like this, by 2050 there will be more plastic than fish in the sea! How does plastic harm sea animals? Fish, sea turtles, and birds think plastic is food, and they eat it. The plastic stays in their stomachs. Dead seabirds are found with stomachs full of plastic. Whales, dolphins, and seals are caught by plastic bags or fishing nets. It’s said that millions of ocean animals die each year because of plastic rubbish in the sea around the world. What can we do? Many people and organizations around the world are taking action. In some countries, plastic bags aren’t allowed to use. Scientists are developing new biodegradable plastic. Many communities are trying to use less plastic and recycle more. Kids are playing their part, such as working to make their schools “zero plastic”. Plastic pollution is becoming more and more serious, so it’s necessary for us to produce, buy and use fewer plastic products. Above all, one person can’t solve it alone, but together we will make a difference. 1. What will happen to the world’s oceans by 2050 according to the passage? A.

How does water get from the roots of a plant to the other parts of the plant? The water travels through “small pipes” to all parts of the plant. And here is a scientific experiment to show it. What we need: How we do it: 1. Put a few drops of the red food colour in the glass of water. 2. Cut the bottom of the celery stick and place the celery in the water. 3. Leave the celery stick in the glass of water for a few hours. 4. Take the celery stick out of water and cut it into pieces across the stern. What happens: You can see red food colour in all cross parts from the bottom of the celery stick right up to the leaves. Why it happens: The water, with the red food colour, has run in the celery stick through the small pipes in it. The experiment, therefore, shows that the small pipes in the plant allow water to reach all parts of it. The red food colour shows where the water has travelled in the celery stick. 1.

Put a few drops of the red food colour in the glass of water. 2. Cut the bottom of the celery stick and place the celery in the water. 3. Leave the celery stick in the glass of water for a few hours. 4. Take the celery stick out of water and cut it into pieces across the stern. What happens: You can see red food colour in all cross parts from the bottom of the celery stick right up to the leaves. Why it happens: The water, with the red food colour, has run in the celery stick through the small pipes in it. The experiment, therefore, shows that the small pipes in the plant allow water to reach all parts of it. The red food colour shows where the water has travelled in the celery stick. 1. Which shows the correct order of the experiment? ① ② ③ ④ A. ①-③-②-④ B. ③-①-②-④ C. ①-③-④-② D. ③-①-④-② 2. According to the experiment, what can you see after cutting the celery stick into cross parts? A. The inside of the celery stick has nothing. B. The water in the celery stick is running. C. The celery stick is bigger and taller. D. All the cross parts are red. 3. What is the aim (目的) of the experiment? A. To tell us plants would die without water. B. To tell us the way water runs through a plant. C. To show doing a science experiment on plants is easy. D. To show how to make colorful leaves by coloring the water. 【答案】CDB 【导语】本文通过一个实验证明水是如何在植物内部传输的。 1. 细节理解题。根据“ Put a few drops of the red food colour in the glass of water.”可知，首先是一杯水里滴几滴红色食用色素，即①；根据“Cut the bottom of the celery stick and place the celery in the water.”可知，然后是切芹菜杆的底部，并把芹菜放在水里，即③；根据“Leave the celery stick in the glass of water for a few hours.”可知，接下来是把芹菜杆置于水中几个小时，即④；根据“Take the celery stick out of water and cut it into pieces across the stern.”可知，最后是将芹菜杆从水中取出，从尾部切成小块，即②；因此正确的顺序为①-③-④-②。故选C。 2. 细节理解题。根据“You can see red food colour in all cross parts from the bottom of the celery stick right up to the leaves.”可知，你可以看到从芹菜杆底部到叶子的所有交叉部分都是红色的食用色素。故选D。 3. 主旨大意题。根据“How does water get from the roots of a plant to the other parts of the plant? ... And here is a scientific experiment to show it.”及全文可知，本文通过一个实验证明水是如何在植物内部传输的。故选B。 1 / 14 学科网（北京）股份有限公司 $$
