8B Unit 8主题阅读训练

主题介绍：Daniel是一个认真践行绿色生活的学生。他每天学习并实践着保护环境的生活方式，为应对气候变化、保护人类家园而努力。最近，他打算参与一项植树的志愿活动。为什么呢？我们一起听听他的想法吧！

 

 I. 气候变化

Daniel认为全球变暖等气候问题是人类发展过程中不容忽视的、亟需解决的问题。而解决这个问题，每个人都需要付出努力。

The world's highest ski place, Chacaltaya, was closed after the 18,000-year-old glacier melted in 2009. Many scientists agree that the glaciers around the world could disappear in this century, much faster than we thought.

As we all know, the reason for this is global warming. When a certain gas such as carbon dioxide (CO₂) is largely emitted into the atmosphere, it causes the greenhouse effect which makes the earth warmer.

As the earth becomes warmer, glaciers melt more quickly, and dark rocks are uncovered. Then these rocks take in more heat, causing the temperature to rise. As a result, the remaining snow on glaciers melts faster.

The effects of global warming will be far-reaching and often devastating. While the melting of glaciers may flood some areas of the earth, in other places, it is making water disappear. An increasing number of heat waves and droughts worldwide will also change the face of the world in the future.

Global warming is a real problem, and one largely caused by human activities. Solving the problem is not easy, and there is no single magic way. However, we can begin by lowering the amount of CO₂ in our daily lives.

Peter Miller, along with his wife, took part in a scientific test to see how much CO₂ they could cut down in a month. The average USA household produces about 80 kilos of CO₂, which was more than twice the European average and almost five times the global average. Their final goal was to produce less CO₂ than most American families.

First, they found out how much CO₂ they were producing. Then they asked an expert for

advice on how to reduce CO₂ emissions. According to the expert's advice, they made some changes to their house, replaced their lights, and changed some of their living habits. At the same time, they either biked, walked, or used public transportation. A month later, they saved 70% on electricity, 40% on gas, and drove half as much as others. Their daily CO₂ emissions were fewer than the USA average, at 32 kilos.

Protecting our planet starts small, change a light, open a window, walk or bike. With a little effort, and not much money, most of us can make a difference.

1. Why was the ski place, Chacaltaya, closed in 2009?

A. Because the ski place was too old.

B. Because few tourists came to this place.

C. Because the ski place was too high to reach.

D. Because the 18,000-year-old glacier melted.

2. How does the writer show that Peter succeeded in the scientific test?

A. By listing numbers.

B. By asking questions.

C. By giving explanations.

D. By giving suggestions.

3. Which of the following can match the information in the passage?

4. What's the structure of this passage?（画出文章的篇章结构）

II.重要的植物

在了解了树木的重要性后，Daniel打算在假期参与一项植树的志愿活动。（有一项多余）

A lot of health care is connected with being around trees. 1._________ According to one 2015 study, a walk in the woods can make you feel seven years younger.

They also do a great deal of good for the environment by reducing air pollution and taking in carbon dioxide from the atmosphere. 2._________ A new study by researchers at University College London found that the trees in the London Borough of Camden store as much carbon per hectare as rainforests.

A tree's ability to take in carbon dioxide is especially useful when the tree is in cities or towns, where there are too many industrial activities. For the study, the researchers used laser scanning methods to take their own carbon readings of trees from the ground as well as the air. 3.__________ They were able to know there are about 85,000 trees in Camden, where the university is based.

They decided that Camden had a median carbon density of around 55 tons of carbon per hectare (t/ha). Greener areas of the borough, like Highgate Cemetery, had a carbon density of 380 t/ha—levels that are typically seen in rainforests. 4.____________

So what exactly does this mean? Trees could help cool the atmosphere by removing carbon dioxide from the air. However, some climate scientists argue that it's more complicated than that. 5.__________ Still, with all of the other benefits trees offer, planting a seed or two couldn't hurt.

A. We need to protect the ones we already have. B. These benefits aren't just felt in the countryside either. C. For comparison, major cities in the USA have a carbon density of 7. 7. D. They have been known to reduce people's stress and improve overall mental health. E. Then they compared their findings with the data from the UK Environment Agency.
