21、When you buy food or other products at the store, you probably don't think much about the people who grew them or made them. That's normal, but many farmers and others involved in producing food and other goods have very hard lives. Farmers work hard to grow crops, but sometimes the weather is bad, and their fields don't produce much. Or sometimes the price of what people produce goes down, and they can't earn enough to support their families. In some industries, workers are not fairly paid to make products cheaper. The fair trade movement tries to solve these problems by taking care of the people whose work benefits consumers.
Fair trade is difficult to define because it includes multiple organizations in many countries. These organizations encourage distributors (分销商) to pay a specified (指定的) minimum price for products. This minimum is often higher than the market price, but it makes sure producers earn enough to make a living. Distributors also pay some additional money that goes to the community that produced the product. This money is spent to thrive the community. For example, they might build a school or dig a well, either of which benefits everyone who uses it.
To be labeled fair trade, products have to be made following certain high standards related to treating workers well and protecting the environment. This can be expensive, but the higher prices paid by purchasers cover the extra costs. These standards can vary from industry to industry to reflect the details of the various production processes.
What does this mean for you? Many fair-trade organizations offer certification for products made with fair-trade ingredients (成分). There are different levels of certification depending on what percentage of the ingredients are fair trade. Certain websites can help you find fair-trade products.
Buying fair-trade products when possible is important because it communicates that you want companies to be involved in fair trade. Businesses need to make money, so manufacturers (制造商) are more likely to use fair-trade ingredients if they know people will pay for them. It's also important for your own integrity. Buying fair trade ensures that you're not benefiting from someone else's suffering. If you want to help more, you can write to companies you buy from and ask them to use fair-trade ingredients. In short, fair trade is about helping people who help you through their labor.
【1】The fair trade movement aims to ________.
A．guide farmers to produce more crops
B．help the people who make the products we use
C．tackle the problem of food shortage in rural area
D．encourage consumers to purchase more products
【2】What does the underlined word "thrive" in Paragraph 2 mean?
A．Rebuild.
B．Develop.
C．Recover.
D．Decorate.
【3】In the fair trade movement, the consumers need to pay a higher price because ________.
A．distributors are in charge of the market price
B．the products labeled fair trade are of higher quality
C．organizations in fair trade encourage them to do so
D．they need to pay for the expense to meet the high criteria
22、What is the purpose of lightning? The new study published at the end of April in Science found that lightning may play a bigger role in global climate change than was previously known by the scientific community.
Many are familiar with the potentially deadly dangers posed by lightning, which is blamed for an average of 43 deaths in the United States each year, based on data from 1989 to 2018. Although the odds of being struck are quite low-1 in 1, 222, 000 in a given year and 1 in 15, 300 in a lifetime many in the weather community have long urged people to take proper precautions to stay safe in storms. However, the researchers recently uncovered a surprising and beneficial impact of lightning.
The study, which included contributions from nine atmospheric researchers across a dozen universities, was based on an airborne research flight conducted by a NASA DC-8 storm-chasing plane in 2012. Researchers initially thought there was a problem with the equipment on the plane, which was being used to measure the hydroxyl radicals (羟基自由基) in the atmosphere until they realized increases they observed corresponded with lightning flashes, ABC News reported.
Hydroxyl radicals, described as a “chemical scavenger (清洗剂) ” by Science Direct, are important chemical compounds found in the atmosphere due to the reactive nature with other organic molecules (分子). Researchers previously understood that lightning could help to clean the atmosphere, but there was no evidence that it could generate compounds like these radicals. “No one has seen that much in the atmosphere from natural processes, ever,” Brune said. As a result, the study estimates that somewhere between 2% and 16% of the oxidizing (氧化), or cleaning that happens naturally in the Earth’s atmosphere, is done by lightning.
Why is this significant? The oxidation process helps to reduce chemicals like carbon monoxide and methane in the atmosphere. These chemicals, known for being greenhouse gases, have been proven to contribute to rising temperatures associated with climate change. Researchers say that more studies will need to be conducted to verify the degree to which lightning contributes to the fight against global climate change.
【1】What do the statistics in Para 2 tell us about lightning?
A．It threatens human lives.
B．It can only harm people.
C．It is a strange phenomenon.
D．It happens quite frequently.
【2】What led to the new discovery in the text?
A．The equipment failure on the storm-chasing plane.
B．The increase of Hydroxyl radicals during lightning.
C．The lightning flashes observed by the research team.
D．The airborne research conducted by NASA scientists.
【3】How does Brune feel about the finding?
A．Doubtful.
B．Amazed.
C．Frustrated.
D．Ambiguous.
【4】What is the main idea of the text?
A．Hydroxyl radicals clean the atmosphere.
B．Oxidizing is a natural result of lightning.
C．Lightning may help address climate change.
D．Greenhouse gases contribute to rising temperature.
23、The Chinese manned submersible(潜水器) Fendouzhe, over 96.5 percent of whose core components have been independently developed by China, reached one of the deepest spots on the planet, a dizzying and dark depth of 10,909 meters.
Extreme water pressure is the first challenge that requires dealing with during the exploration. At 10,000 meters down in the ocean, the submersible has to stand about 1,100 atmospheres of pressure, equal to 2,000 elephants stepping on a person’s back. As the solid “armour (盔甲)”，the manned cabin is a safety guarantee for humans to reach down to 10,000 meters deep in the ocean. To overcome the technical bottleneck, the Chinese researchers developed a new material-Ti62A, successfully solving problems of the strength and toughness of the manned cabin.
To avoid risks of crashes in the dark deep sea with complex terrain(地形)，Fendouzhe requires its control system, a smart “brain” to give the exact instructions. Researchers designed a neural network algorithm(神经网络算法), which enables Fendouzhe to travel automatically according to the seabed terrain and locate fixed points. Its control system has reached the international frontier level.
The submersible is equipped with two flexible and strong “arms”. Each 7-joint arm with 6 degrees - of - freedom control and a weight-carrying ability of more than 60 kilograms can cover the sampling basket and its front areas. With the arms, Fendouzhe collected samples of ocean rocks, deep-sea living things and seabed sediments(沉淀物).
The ocean, especially the deep sea, is widely regarded as Earth's final frontier. Deep down in the ocean are unusual creatures, strange environments and impressive geological wonders, yet humanity knows less about the ocean floor than about the far side of the moon. These samples and data collected from the deep ocean can be used for geological and biological research, as well as study the human impact on the planet.
【1】Why is “2000 elephants” mentioned in paragraph 2?
A．To make the numbers accurate.
B．To provide a biological explanation.
C．To emphasize the importance of the task.
D．To describe the degree of the pressure vividly.
【2】What can “arms” do according to paragraph 4?
A．Collect ocean samples.
B．Land the submersible.
C．Provide safety guarantee.
D．Prevent crashes intelligently.
【3】Which of the following has reached the world advanced level ?
A．The toughness of the cabin.
B．The ability of weight-carrying.
C．The method of data-collection.
D．The technology of control system.
【4】Why do people research the deep ocean according to the last paragraph?
A．It is more complex than the moon.
B．It is seriously affected by humans.
C．To make sure of the depth of the ocean.
D．To explore the less-known field of the planet.
