Unit 1 Fresh start Quiz 1

1、 问题:Living in an urban area with green spaces has a long-lasting positive impact on people’s mental well-being, a study has suggested. UK researchers found moving to a green space had a sustained positive effect. Co-author Mathew White, from the University of Exeter, UK, explained that the study showed people living in greener urban areas were displaying fewer signs of depression or anxiety. “There could be a number of reasons,” he said, “for example, people do many things to make themselves happier; they strive for promotion or pay rises, or they get married. But the trouble is that within six months to a year, people are back to their original baseline levels of well-being. So, these things are not sustainable; they don’t make us happy in the long term. ”Dr. White said his team wanted to see whether living in greener urban areas has a lasting positive effect on people’s sense of well-being or whether the effect also disappeared after a period of time. To do this, the team used data from the British Household Panel Survey compiled by University of Essex.“What you see is that even after three years, mental health is still better, which is unlike many other things that we think will make us happy.” He observed that people living in green spaces were less stressed, and more sensible and communicated better.With a growing body of evidence establishing a link between urban green spaces and a positive impact on human well-being, Dr. White said “There’s growing interest among public policy officials, but the trouble is who funds it.”1. According to a study, what do green spaces do to people?
选项:
A:Improve their work efficiency.
B:Add to their sustained happiness
C: Help them build a positive attitude towards life.

Unit 2 Loving parents, loving children Quiz 1

1、 问题:Popping food into the microwave for a couple of minutes may seem utterly harmless, and Europe’s stock of these quick-cooking ovens emit as much carbon as nearly 7million cars, a new study has found, and the problem is growing. With costs falling and kitchen appliances becoming "status" users, owners are throwing many microwave after an average of eight years. This is pushing sales of new microwave which are expected to reach 135 million annually in the EU by the end of the decade.A study by the University of Manchester worked out the emissions of carbon dioxide — the main greenhouse gas responsible for climate change — at every stage of microwaves, from manufacture to waste disposal.     "It is electricity consumption by microwaves that has the biggest impact on the environment," say the authors, who also calculate that the emissions from using 19 microwaves over a year are the same as those from a car. According to the same study, efforts to reduce consumption should focus on improving consumer awareness and behaviour to use appliances more efficiently. For example, electricity consumption by microwaves can be reduced by adjusting the time of cooking to the type of food."However, David Reay, professor of carbon management argues that, although microwaves use a great deal of energy, their emissions are minor compared to those from cars. In the UK alone and these emit way more than all the emissions from microwaves in the EU. Backing this up, recent data show that passenger cars in the UK emitted 69m tonnes of CO2 in 2015. This is 10 times the amount this new microwave oven study estimates for annual emissions for all the microwave ovens in the whole of the EU. Further, the energy used by microwaves is lower than any other form of cooking. Among common kitchen appliances used for cooking, microwaves are the most energy-efficient, followed by a stove and finally a standard oven. Thus, rising microwave sales could be seen as a positive thing.1. What is the finding of the new study?
选项:
A:A) Quick-cooking microwave ovens have become more popular.
B:B) The frequent use of microwaves may do harm to our health.
C:C) CO2 emissions constitute a major threat to the environment.
D:D) The use of microwaves emits more CO2 than people think.
答案: 【D) The use of microwaves emits more CO2 than people think.

2、 问题:2. Why are the sales of microwaves expected to rise?
选项:
A:A) They are becoming more affordable.
B:B) They have a shorter life cycle than other appliances.
C:C) They are getting much easier to operate.
D:D) They take less time to cook than other appliances.
答案: 【A) They are becoming more affordable.

3、 问题:3. What recommendation does the study by the University of Manchester make?
选项:
A:A) Cooking food of different varieties.
B:B) Improving microwave users’ habits.
C:C) Eating less to cut energy consumption.
D:D) Using microwave ovens less frequently.
答案: 【B) Improving microwave users’ habits.

4、 问题:4. What does Professor David Reay try to argue?
选项:
A:A) There are far more emissions from cars than from microwaves.
B:B) People should be persuaded into using passenger cars less often.
C:C) The UK produces less CO2 than many other countries in the EU.
D:D) More data are needed to show whether microwaves are harmful.
答案: 【A) There are far more emissions from cars than from microwaves.

5、 问题:5. What does Professor David Reay think of the use of microwaves?
选项:
A:A) It will become less popular in the coming decades.
B:B) It makes everyday cooking much more convenient.
C:C) It plays a positive role in environmental protection.
D:D) It consumes more power than conventional cooking.
答案: 【C) It plays a positive role in environmental protection.

Unit 3 Digital campus: blessing or curse Unit 3 Quiz1

1、 问题:PepsiCo is to spend billions of dollars to develop drinks and snacks and reformulate existing ones with lower sugar, salt and fat, as consumers demand healthier options and regulatory pressure intensifies amid an obesity epidemic. The maker of Mountain Dew and Gatorade has been one os me earlier movers in the industry to offer products with reduced levels of unhealthy ingredients — PepsiCo claims a packet of its chips now contains less salt than a slice of white bread. However, its new 10-year plan makes clear it believes it still has a long way to go.Shifting eating habits, including a sharp drop in consumption of sparkling drinks, have forced radical change on the industry. But those shifts have yet to be reflected in record obesity levels, which stand at 36. 5% overall in the US.   Indra Nooyi, PepsiCo chairman, said the plan to make its products healthier was important for the company’s growth. But on the subject of obesity, she pointed out that consumers’ lifestyles have changed significantly, with many people being more sedentary not least because more time is spent in front of computers. She said Pepsico’s contribution was to produce healthier snacks that still tasted good. "Society has to change its habits, " she added. “We can’t do much to alter sedentary lifestyles, but we can provide consumers with great-tasting products, low in salt, sugar and fat. In the past we had to have a taste trade-off. But we re breaking that trade-off. But we are breaking that trade-off.”PepsiCo’s plan for its foods and drinks is based on guidelines from the World Health Organisation, which last week backed using taxes on sparkling drinks to reduce sugar consumption. Initiatives also include efforts to reduce its environmental impact, water consumption and materials used in packaging by 2025. PepsiCo did not say exactly how much it planned to invest to reach its goals. However, Dr Mehmood Khan, chief scientific officer, said the company had doubled research and development spending in the past five years and was "committed to sustaining investment", adding that companies cannot cost-cut their way to increasing sales. PepsiCo’s research and development budget in 2015 was $ 754 million. 1. Why is PepsiCo making a policy change?
选项:
A:To win support from the federal government.
B:To be more competitive in the global market.
C:To satisfy the growing needs for healthy foods.
D:To invest more wisely in the soft drink industry.
答案: 【To satisfy the growing needs for healthy foods.

2、 问题:What does PepsiCo think it will have to do in the future?
选项:
A: Invest more to develop new snacks.
B:Reduce levels of obesity in the US.
C:Change consumers’ eating habits.
D:Keep on improving its products.
答案: 【Keep on improving its products.

3、 问题:Why does PepsiCo plan to alter its products, according to Indra Nooyi?
选项:
A: To ensure the company’s future development.
B:To adapt to its customers’ changed taste.
C:To help improve its consumers’ lifestyles.
D:To break the trade-off in its product design.
答案: 【 To ensure the company’s future development.

4、 问题:What does Indra Nooyi say about the obesity epidemic?
选项:
A:It is mainly caused by over-consumption of snacks.
B:It results from high sugar and salt consumption.
C:It is attributable to people’s changed lifestyles.
D:It has a lot to do with longer working hours.
答案: 【It is attributable to people’s changed lifestyles.

5、 问题:What has PepsiCo been doing to achieve its objective?
选项:
A:Studying WHO’s guidelines.
B:Increasing its research funding.
C:Expanding its market overseas.
D:Cutting its production costs.
答案: 【Increasing its research funding.

Unit 4 Heroes of our time Unit 4 Quiz1

1、 问题:The latest in cat research reveals that the lovely animal seems to have a basic grasp on both the laws of physics and the ins and outs of cause and effectAccording to a newly published study, cats seem to be able to predict the location of hiding prey using both their ears and an inborn understanding of how the physical world works.In a recent experiment, Japanese researchers taped 30 domestic cats reacting to a container that a team member shook. Some containers rattled; others did not. When the container was tipped over, sometimes an object fell out and sometimes it didn’t. It turns out that the cats were remarkably smart about what would happen when a container was tipped over. When an object did not drop out of the bottom of a rattling container, they looked at it for a longer time than they did when the container behaved as expected."Cats use a causal-logical understanding of noise or sounds to predict the appearance of invisible objects,” lead researcher Saho Takagi says in a press release. The researchers conclude that cats’ hunting style may have developed based on their common-sense abilities to infer where prey is, using their hearing. Scientists have explored this idea with other endearing creatures: babies. Like cats, babies appear to engage in what’s called "preferential looking” — looking longer at things that are interesting or unusual than things they perceive as normal.When babies’ expectations are violated in experiments like the ones performed with the cats, they react much like their animal friends. Psychologists have shown that babies apparently expect their world to comply with the laws of physics and cause and effect as early as two months of age. Does the study mean that cats will soon grasp the ins and outs of cause and effect? Maybe. Okay, so cats may not be the next physics faculty members at America’s most important research universities. But by demonstrating their common sense, they’ve shown that the divide between cats and humans may not be that great after all.1. What do we learn from a newly published study about cats?
选项:
A: They can be trained to understand the physical world.
B:They know what kind of prey might be easier to hunt.
C:They have a natural ability to locate animals they hunt.
D:They are capable of telling which way their prey flees.
答案: 【They have a natural ability to locate animals they hunt.

2、 问题:What may account for the cats’ response to the noise from the containers?
