2 . If you're feeling hungry, what’s the easiest way to satisfy your Hunger? Many of Us will reach for a takeaway menu and order some delicious-but possibly unhealthy -food. And our increasingly hectic lives add to our need to buy ready-made food because we always have no time or energy to cook on our own.

Eating options are endless, and new technology means we can feed our desire at the push of a button. Takeaway delivery apps make ordering food quick and convenient. It's estimated that in the UK alone, people eat three million takeaway meals a day, and the three biggest delivery apps together offer a choice of 100 foods from 60,000 restaurants. Amelia Brophy, head of UK Data Products at YouGov, told the BBC that its research suggests that the frequency of takeaways ordered is expected to increase in the future.

It’s no wonder we are tempted to skip the grocery shopping, bypass the kitchen, and tuck into something that someone else has prepared. But ordering a pizza, a spicy curry or a box of noodles, can come at a price both financially and to our health. Eating too much processed and unhealthy fast food has some effect on obesity and the risk of developing certain diseases. A few years ago, the BBC Good Food Nation Survey found most people eating fast food on average two days per week gradually putting on weight.

Of course, reducing salt, sugar and fat is one way to make takeaway food healthier, as well as offering smaller portion sizes. But the best advice for you is to find a recipe book and try making your own nutritious meals. And if you haven't got time, try ordering a healthier alternative from the menu.

1. What does the underlined word “hectic” in Paragraph 1 probably mean?

A．Abnormal.

B．Busy.

C．Irregular.

D．Social.

2. What has made takeaway foods even more popular nowadays?

A．The various food.

B．Their delicious taste.

C．Their relatively low price.

D．The advanced technology.

A．Takeaway foods may do harm to health.

B．Takeaway foods make people light-hearted.

C．Pizza and noodles are the most popular takeaway foods.

D．The UK has the largest number of people ordering takeaway foods.

4. What is the author’s purpose of writing the last paragraph?

A．To give readers some suggestions.

B．To offer readers an alternative menu.

C．To find the reason for ordering takeaway foods.

D．To choose the best way of making nutritious meals.

4 . A customer stands on the other side of the counter at my work, eyeing the menu. “The food here is so caloric,” she complains, and then looks at me. “You don’t eat here, do you? It certainly doesn’t look like it.” My face turned red.

I’m not quite used to how others see me. Since June 2018, I’ve lost almost 50 pounds. When I made the choice to change my body physically, everyone around me told me that I would be happier: Skinny meant pretty, and pretty meant happy and satisfied. After looking through dozens of before-and-after changes on Instagram and other social media, I was more eager to make myself smaller, to better fit into the world. But none of that happened. I didn’t feel more whole, or more peaceful. More than anything, I felt lied to.

Human health is unbelievably complex, and there’s so much more to our well-being than caloric balance. For several months, I often felt very tired and got angry easily, convinced that my body was a machine and I had to hard-wire it to look as physically perfect as possible. But at the end of the day, I realized that saying no to my body’s natural desire only left me feeling upset.

Our world is filled with losing weight. Nearly every time I listen to the radio, I hear some ads criticizing empty promises of giving you a better body, achieved only by this gym membership/ this prepackaged Keto shake/ this waist trainer. These all live by the same message: That food is dangerous, and the less we eat, the better off we are. In extreme cases, this message can lead to eating disorders, which will affect over 30 million people in their lifetimes, according to the Body Image Therapy Center.

These ideas could not be further from the truth. We eat food for a reason: It gives us energy, it keeps our body functioning, and it makes us human. I urge everybody to adopt a diet based on sustainability (可持续发展), to eat for energy, based on what makes us happy. We all deserve healthy relationships with food and mindful eating is the best place to start.

D．They mislead some youths into having wrong ideas of beauty.

5 . Having worked for more than a decade in finance in the oil industry in Canada, Tori Fahey found herself wanting more from life. But it wasn't through desperation that her circumstances changed: “I didn't get fed up and storm off, nothing like that; it was curiosity about other interests and wanting to experience something new.”

Fahey left her job and completed an MBA before setting up a move to New York to begin a degree. However, the opportunity of an open year between the MBA and the degree came up, and as a keen touring cyclist, Fahey realised that a much dreamed-about adventure was now becoming a possibility: "The ride in Africa had been on my fantasy list. It was a moment when I realised that I could do anything, so I should."

Fahey rode across Africa, a 7,500-mile trip that took four months. The whole experience had a life-changing impact. Fahey said: “Bicycles provide a literal freedom. You don't allow yourself to feel like that in everyday life because there are so many distractions. But when you' re out on the bike and there's nothing else, you' re really free to experience what life is.”

Post-degree, Fahey worked on projects with the UNDP(United Nations Development Project) in Montenegro with the aim of bringing investment to rural communities.

It was while working on these projects that the seeds were sown for the next new investment. “It was through my trip across Africa that I discovered pannier and rack systems inconvenient and I was never going to use them again.” Little did she know this would lead her to start up her own company.

In 2013, Apidura was born, producing storage solutions for people looking to travel the world by bike, race across continents and carry all they need to do so. It's now a successful global brand, but Fahey remains reflective about what else the company can do for people.

A．A tough path to fame.	B．An adventure across Africa.
C．The benefits of green travelling.	D．The story behind the birth of Apidura.

6 . Earl Forlales, a graduate in Materials Science and Engineering, took inspiration from the bamboo hut his grandparents lived in outside Manila and created a house made of bamboo that can be put together in four hours to solve the chronic(长期的) shortage of affordable accommodation in the Philippines. His design won a £50.000 top prize from the Royal Institute of Chartered Surveyors (RICS) in its Cities for our Future competition.

His house, known as Cubo, could be produced in a week, constructed in four hours and costs £60 per square meter. Its use of bamboo—which releases 35％ more oxygen into the environment than trees—was praised by the judges. The ability of the houses to be constructed in any bamboo-producing area was one of the key attractions.

“The world’s cities are growing all the time and there is a real need to make sure they are safe, clean and comfortable places to live in,”John Hughes, the competition’s head judge and then president at RICS, said. “As we look at our competitors, who are our next generation of leaders， I believe that real progress will be made in tackling the world’s biggest issues.

Forlales has already identified a suitable area of land to start building his Cubo houses. He plans to begin the work next year with experts from the RICS in an attempt to help relieve the huge pressure on housing in Manila, where a third of the 12 million population live in poor districts. He said, “I would like to thank RICS for the opportunity, and look forward to working with them to put this money to good use in Manila and then hopefully elsewhere around the world.”

1. What contributes most to Forlales’ winning the prize？

A．The material of his house.	B．The shape of his house.
C．The design of his house.	D．The expense of his house.

2. Which word can best replace the underline word “tackling” in Paragraph 3?

A．A Competition in House Building	B．A Man Devoted to City Development
C．The Bamboo House Winning a top Prize	D．The Way to Solve Housing Shortage

7 . I am proud to be a member of two cultures. Even though I am only ten years old, I have lived in two countries and in two cultures. I have lived in both Mexico and the United States.

I was born in the state of Michoacán. I was born in a small town called Quinceo. Life there was simple and peaceful. There was a small market where we would go on Sundays. There was a corral where we would go and watch rodeos. After school, my friends and I would go for a swim in a creek. My mom did not work; she stayed at home taking care of our family. Life in Quinceo was nice, but money was sometimes not enough to support us.

In 1996, the day came when my dad decided to bring us to the United States. Leaving my town was hard, but it was important that my family stay together. When I left Mexico, I had a lot of special friends and nice teachers.

When I first came to the United States, I started at a new school in Chicago. I found care and company at the school, among Hispanic people, my friends, and my teacher. She helped me all the time.

My education now is different from the one in Mexico. Here, I am studying in two languages. I feel very happy because I am able to communicate in two languages. In my case, speaking Spanish is an indication of my Mexican heritage. Speaking English is a symbol of my triumph and the struggles that I have as an immigrant in this country. Now that I have been here three years, I am proud to offer my help and support to people who need it.

I urge those who come from Mexico and other countries to learn English and to continue speaking their native language, too. It will help them reach out to others.

8 . If your fingers get chilly all year round—even in the peak of summer—you’re not alone. Many people get cold hands during all of the seasons, due to a number of causes, from genetic to chronic illnesses.

Common reasons include being elderly and thin. If your hands are regularly cold or numb, however, it’s a good idea to see a doctor to rule out more serious causes. Cold hands are one of the symptoms of both anemia (贫血症) and hypothyroidism (甲状腺机能减退). Diabetes, which reduces blood circulation, can also trigger it. And if your heart is weak from heart disease, your body may prioritize sending blood to your core over your limbs.

For many others, cold hands are a sign they have a largely harmless condition called Raynaud’s disease. When any of us goes out in the cold, our bodies activate the muscles in our smallest blood vessels to make them even smaller—a survival mechanism to keep blood, and thus warmer temperatures, in our core. For people with Raynaud’s, this reaction is too strong, and instead of just a bit less blood going to their fingers, far too little gets there.

Raynaud’s is more common in women, and it most often develops before the age of 30. In fact, if you develop Raynaud’s when you’re older—usually after 40—it can be a sign of another underlying issue. That could be a smaller problem—a previous incident of frostbite (冻伤) or a sign of a more serious autoimmune condition, like lupus (狼疮).

For the majority of people living with Raynaud’s, medication won’t be necessary. However, a rare, more severe form of Raynaud’s affects less than one in 1,000 people. In these cases, blood can become completely blocked, causing sores on the hands. If they go untreated, it can lead to gangrene (坏疽) and, very rarely, amputation (截肢).

9 . To address the plastic pollution troubling the world’s seas and waterways, Cornell University chemists have developed a new polymer (聚合物) that can degrade (降解) plastic when exposed to ultraviolet radiation, according to the research published in the Journal of the American Chemical Society.

“We have created a new plastic that has the mechanical properties required by commercial fishing gear. If it eventually gets lost in the water environment, this material can degrade on a realistic time scale,” said lead researcher Bryce Lipinski, professor of chemistry and chemical biology at Cornell University. “This material could effectively reduce persistent plastic accumulation in the environment.”

Commercial fishing contributes to about half of all floating plastic waste that ends up in the oceans. Fishing nets and ropes are primarily made from three kinds of polymers, none of which easily degrade. “While research of degradable plastics has received much attention in recent years,” Lipinski said, “obtaining a material with a mechanical strength comparable to commercial plastic remains a difficult challenge.”

Coates and his research team have spent the past 15 years developing the new plastic called isotactic polypropylene oxide, or iPPO. While its original discovery was in 1949, the mechanical strength of this material was unknown before this recent work. The high isotacticity and polymer chain length of their material makes it different from previous plastics and provides its mechanical strength.

Lipinski and other scientists want no race of the polymer to be left in the environment. He notes there is precedent (先例) for the biodegradation of small chains of iPPO which could effectively make it disappear and ongoing efforts aim to prove this.

1. What is the feature about the new polymer?

A．It can solve the problem of plastic consumption.

B．It can degrade plastic waste in the sea water.

C．It has been developed to solve plastic pollution.

D．It has been developed to lower fishing costs.

2. What can we infer from paragraph 3?

A．It requires great effort to invent the new plastic.

B．Fishing should be forbidden in the sea.

C．Fishing nets and ropes are not the major pollution source.

D．Degradable plastics were not paid attention to until recent years.

3. What did the recent study find about iPPO?

A．Its original discovery.	B．Its mechanical properties.
C．Its complex structure.	D．Its mechanical strength.

4. What is Lipinski’s attitude towards the future of iPPO?

A．Doubtful.	B．Promising.
C．Unconcerned.	D．Disapproval.

10 . Today we know Antarctica as an extreme environment containing ice and snow. But new research provides evidence that the area was very different in the past.

The evidence was found inside a piece of earth sediment(沉积物) collected by researchers from a depth of about 30 meters below the ocean floor off the coast of Antarctica. In the sediment, they found forest soil estimated to be about 90 million years old. This would have been in the Cretaceous Period, when dinosaurs were the main land animals.

Johann Klages is a geologist, working in the Institute's Helmholtz Center for Polar and Marine Research in Germany. He said an examination showed that the material formed on land, not in the ocean.

The researchers estimate that the area – about 900 kilometers from the South Pole – had average yearly temperatures of about 12 to 13 degrees Celsius. During the warmest summer months, average temperatures likely reached between 20 to 25 degrees Celsius. The average yearly temperature in that area is about 40 degrees below zero Celsius.

The examination results showed “a dense network of roots that spread through the entire soil layer,” the Helmholtz Center said in a statement.

The dark brownish-gray soil included fine dirt particles and hard clay, as well as substances linked to at least 65 different kinds of plants, the study found. Klages put that the plants included trees, ferns and flowering plants and while no animal remains were found, there were likely dinosaurs, flying reptiles and many insects in the environment.

The researchers said that the rainforest environment in Antarctica was especially surprising because each year, the area experiences a four-month polar night when there is no sunlight to fuel plant life.
