6 . Pollution

Pollution happens when the environment is dirtied, by waste, chemicals, and other harmful substances(物质).Pollution is a problem all over the world. But it is especially bad in large cities with a lot of industries and cars.    1    

Wildfires, volcanoes, and industrial chemicals cause some air pollution. But most air pollution comes from burning fossil fuels (矿物燃料）These include coal, oil and natural gas. The burning of fossil fuels may release harmful gases. Air pollution may cause such diseases cancer and asthma. It also leads to polluted rain that can harm living things    2     Finally, air pollution damages the ozone layer(臭氧层)which is important because it protects Earth against harmful rays from the sun.

Causes of water pollution are easy to see. People dump(倾倒) garbage and dirty water into river, lakes and oceans. Factories or cities sometimes release poisonous chemicals, and other wastes into water. These chemicals may make the groundwater unfit to drink.    3    

Littering, or throwing garbage on the ground, is a form of land pollution. Litter can destroy the habitats of plants and animals. The buildup of dangerous chemicals in the ground is another form of land pollution. The chemicals may come from farms or factories.    4     They may even harm people who eat the polluted plants and animals.

Many governments, environmental groups, and ordinary people are working to control pollution. Governments have passed laws to keep people from releasing dangerous chemicals into the environment     5     Instead they are getting power from the sun, wind, water, and other energy sources to produce less pollution. Many communities use recycling to reduce pollution.

A．Farmers use chemical to help crops grow.

B．This type of pollution may be seen in big cities.

C．They also can harm fish and other forms of life.

D．These chemicals can spread to plants and animals.

E．In addition, air pollution may be a cause of global warming.

F．There are three main forms of pollution: air, water, and land.

G．Some companies and people are trying to use fewer fossil fuels.

7 . Organic produce has become increasingly popular in recent years. However, "organic" does not mean "pesticide-free"（无农药的）or "chemical-free". In fact, organic farmers are allowed to use a wide variety of chemical sprays and powders on their crops.

    1     It means that these pesticides, if used, must be got from natural sources, not synthetically（人工合成地）manufactured. Also, these pesticides must be applied using equipment that has not been used to apply any synthetic materials for the past three years.     2     What's more, most organic farmers, and even some conventional farmers, employ mechanical and cultural tools to help control pests.

Many people believe organic produce is healthier and safer. Nobody bothered to look at whether natural chemicals are harmful.     3     But when the studies were done, you found that about half of the natural chemicals studied could cause cancer.     4     We assume that "natural" chemicals were better and safer than synthetic materials, but we were wrong.     5    

A．And the land being planted cannot have been-treated with synthetic materials for that period either.

B．Thus, we should be more cautious in our acceptance of "natural" as being harmless.

C．There are many choices and decisions that we, as consumers, are asked to make.

D．It should be noted that we don't know which system is more harmful.

E．This is a case where everyone made the same dangerous mistake.

F．That was because it was assumed that they posed little risk.

G．So what does organic mean?

8 . Just when you thought you were taking care of your health by eating enough fruit and vegetables every day, new research has come out revealing that you might be swallowing microplastic particles(颗粒)along with all those vitamins, minerals, and fiber. A groundbreaking study published in the journal Environmental Research has found that fruits and vegetables absorb microplastic particles from the soil and move them through vegetal tissues, where they remain until eaten by hungry diners, thus getting transferred to human bodies.

The researchers, who are from the University of Catania in Italy, as well as Sousse and Monastir universities in Tunisia, analyzed a variety of common fruits and vegetables---carrots, lettuce, broccoli, potatoes, apples, and pears. These were chosen for the fact that they are frequently consumed, usually one per day, which allowed the researchers to better assess the dietary intakes of MPs (microplastic particles) and NPs (nano-plastics). The samples were purchased from different sources in the city of Catania, including a small fruit vendor and a supermarket.

The researchers found that apples, followed by pears, were the most polluted fruit samples, and carrots were the most polluted vegetable. In the study’s discussion section, the authors wrote, “We can assume that the fruits contain more MPs not only because of the very high vascularization(血管化)of the fruit pulp (果肉) but also due to the greater size and complexity of the root system and age of the tree (several years) compared to the vegetables (60-75 days for the carrot).”

This study is important because it’s the first to detect microplastics in fruits and vegetables. They have been found in other sources before, such as sea salt, beer, water(bottled, in particular), shellfish, sugar, soil, and even air, but never inside fresh produce. It’s an alarming discovery that raises yet another red flag about microplastic pollution in the natural environment.

It’s an area that will likely see a lot more attention in coming years, with the study authors calling for further research into the question of microplastic and whether it harms the health of both plants and humans.

1. What is the study about?

A．The main cause of soil pollution.

B．The great changes in people’s diets.

C．The benefits of eating fruits and vegetables.

D．The microplastic pollution in fruits and vegetables.

2. Why did researchers choose frequently eaten fruits and vegetables?

A．To lower the cost of the study.	B．To gain widespread acceptance.
C．To improve the accuracy of the study.	D．To reduce the time for preparing the samples.

3. What makes the study quite special?

A．It showed the influences of MPs on plants.

B．It proved the source of microplastic pollution.

C．It presented the danger of MPs to human’s body.

D．It discovered MPs in fresh produce for the first time.

4. What do the study authors think of the research on microplastic?

A．It needs to be further studied.	B．It wasted them quite a lot of time.
C．It has raised people’s awareness of health.	D．It has attracted people’s attention to diets.
