In recent years, organic farming ________ (popularity), so our class had a discussion about it. ________ (opinion, topic).
80% of students are in favor of it. Firstly, they think organic farming ________ (beneficial, environment) by reducing the level of pollution. Secondly, it reduces the costs of agricultural production. However, 20% of them insist that now organic food ________ (meet, demand), and that there is still a long way for organic farming to provide sufficient food.
In my opinion, we should ________ (attitude, organic farming), and I believe that it will be very mature in the future.
A. Brusatte said that becoming smaller was “a common way that mammals deal with climate change”. He added, “That’s not to say every species of mammal would get smaller, but it seems to be a common survival trick of mammals when temperatures rise pretty quickly. Which does raise the question: If temperatures do rise really quickly, might humans become shorter, might humans get smaller? And I think that’s certainly reasonable.”
B. Lister doubts that humans will be shorter as the climate heats. “We are not really controlled by natural selection,” he said. “If that was going to happen, you’d need to find large people dying before they could reproduce because of climate warming. That is not happening in today’s world. We wear clothes, we have got heating, we have got air conditioning if it is too hot.”
C. “The climate crisis may lead the human race to shrink in size, as mammals (哺乳动物) with smaller frames appear better able to deal with rising global temperatures,” a leading fossil expert has said. Prof Steve Brusatte, a professor at the University of Edinburgh also notes that animals in warmer parts of the world today are often smaller than those in colder areas.
D. Another study has showed that researchers studying human remains over the past million years have also suggested that temperature is a major predictor of body size change, while scientists studying red deer have said that warmer winters in northern Europe and Scandinavia may lead to the body size of these animals becoming smaller.
E. However, not all experts agree that rising temperatures cause mammals to shrink. Prof Adrian Lister, of the Natural History Museum in London, said the relationship shown by the recent human remains study is weak, while the strong relationship between temperature and mammal body size may often be down to the availability of food and resources.
Hello, everyone! I have just come back from a wonderful trip to Tibet. It was so beautiful there that I felt I was in a fairyland. The scenery was so impressive and the air was pretty fresh and clean.
A. It’s already affecting nearly every aspect of our lives and our children’s futures, our heat waves more deadly, our storms more intense, and our wildfires burn.
B. But the most important thing we can give them is hope that there are solutions, and everyone has something to contribute no matter how old they are.
C. As parents, many of us have had challenging conversations with our children. There’s one more to add to the list — climate change.
D. By taking the time to understand how we feel about climate changes ourselves and then listening to our children discussion about their hopes around the issue, we can help them figure out how they can be part of the solution.
E. When we talk to our kids, we have to be honest. Climate change is real and serious.
We require healthy water and air, and so do we require healthy soil. It makes water clean and serves as a growing medium, It provides a living space for billions of organisms. And it also provides us with food. Therefore, we should do something to protect the soil.
One of the easiest ways we can support the soil is by wasting less food. All the food that ends up in our shopping bags requires land, water and energy to produce. By throwing away less, we will prevent materials in soil from being wasted.
By eating different types of foods, we can help create demands for different farming products, which is better for soil. Food diversity can improve soil quality. In general, eating a diverse (多样的) diet is better for our health too.
Read the instructions on garden products.
When we walk through any garden store, there are many products for our gardens. No matter which product we end up selecting, the most important step before using it is to read the instructions, Misuse can cause problems.
If we are looking to fertilize (施肥) our garden，we need to know what materials are already in the soil before adding more. Or, we might just need to add one specific material, and not others. Local university laboratories can help provide information on testing soil. It’s usually a matter of digging up soil from a few areas of the yard and sending it in to the lab!
A. Buy less food.
B. Eat a diverse diet.
C. Perform soil tests.
D. Reduce food waste.
6 . Landslides and earthquakes are even more dangerous now than in the past because around half of the world’s population now live-in cities. Many people in cities and towns in South America and Asia are at risk from landslides. In April 2017,the city of Mocoa in Colombia was hit by a landslide, leaving many dead and injured. A great number of people live at risk from earthquakes too. These have claimed more than 1.6 million lives in the last hundred years.
Most disaster experts believe that things could get a lot worse. Professor Hou Ming of Peking University studies volcanoes. He warns that the world has not seen the worst yet. The worst eruption in human history was probably Mt Tambora in 1815,in Indonesia. Dust from the volcano rolled across the Earth’s skies. There was no summer in Europe and America the following year. But evidence shows that 73,000 years ago there was a much greater eruption. “It reduced temperatures by maybe 6°C in some places, and the whole planet was sent into winter for years. And there are about two of these events every 100,000 years...”
Why is Mt Tambora mentioned in the text?
| A．To demonstrate the world could get worse. |
| B．To show volcano eruptions have taken many lives. |
| C．To explain a natural disaster by showing an example. |
| D．To describe the worst volcano eruption in human history. |
A. The giant panda used to have a population of 1, 114 in the 1970s. It now totals 1, 864 thanks to 52 protection areas.
B. China will continue its efforts of the wildlife protection. Key projects will be continually carried out to improve protection, including making the lists of wild animals and plants under State protection, and also fighting against illegal wildlife trade, which includes ivory(象牙).
C. In recent decades, a series of wildlife-protection movements have been carried out by the central government. Several species in danger of extinction have made impressive progress .
D. Another species was once thought to be extinct. In 1981, only seven crested ibises were found in Yangxian county, Shaanxi Province. Since then, breeding programs have helped the population reach 2, 000.
E. China has made great improvements in environmental protection during the past 70 years. Protecting wildlife is, without doubt, an important part.

A. These homes can easily collapse during earthquakes or slip and slide downhill in landslides, especially after heavy rain.
B. On the top of that, there is the added aspect of global warming. This has mainly been caused by the huge amount of carbon dioxide produced by factories and vehicles.
C. The reason why nature is beginning to turn on us is that overpopulation. The population of the world is growing at the rate of 10,000 people an hour, nearly 90 million a year.
D. The destruction of the world’s forests plays a part, too. As a result, a hotter ocean causes stronger winds. Atlantic hurricanes are 40% stronger now than they were 30 years ago.
E. Most of the growth is in the developing world. Poor people in agricultural areas often move to the cities. They build homes from whatever materials they can find.
10 . The Last Straw?
Every second, the world uses 160,000 plastic bags — that is a total of over five trillion per year. Up to 99 percent of these plastic bags hang around for at least 1,000 years and pollute Earth. And yet, plastic bags are hardly a necessity in our lives. Of all the changes we could make to create a more sustainable lifestyle, a total ban on plastic bags should be simple.
At the beginning of 2021, Shanghai put in effect a ban on all plastic bags in shopping malls and supermarkets, as well as a ban on non-degradable plastics in many other areas. Over the years, individuals and companies have worked to replace plastic items, such as cups and straws, with paper ones.
Customers complain that paper straws often become soft and break before they can finish their hot drinks. Experts, however, have repeatedly stressed plastic substitutes (替代品) are not the ultimate solution, and that our consumption habits need a bigger change.
In college, one of my environmental science professors promoted a type of waste-free living. She carried around a small glass jar with her, and in it was all her trash she collected for the entire year. She was able to do this by bringing her own cup to Starbucks, her own bags to the shops, and never buying anything that came wrapped in plastic. Her food waste also became compost.
Plastic bags are incredibly easy to forget about when they become increasingly common.
| A．Clearly she demonstrated our ability to live a completely healthy life without creating a great deal of plastic waste. |
| B．Plastic bag litter has even caused great problems in some areas. |
| C．If they’re free to use and easily disposed of, they’re a mere tool that we don’t have to think about. |
| D．Some of these decisions have been met with criticism. |
| E．Unfortunately, such a high level of pollution doesn’t come without consequences. |
