1 . 阅读下面材料，根据其内容和所给段落开头语续写两段，使之构成一篇完整的短文。

Jayce began noticing when he was in kindergarten that he looked different from his classmates. They had two hands while he had one. Due to their young age, Jayce was encouraged that he was just like an angel with one wing folded to prepare for something.

It started when one boy laughed at him. From that day, 5-year-old Jayce turned sad. He returned home with questions. “Why am I different? Why me? Why?” He cried to ask his mother, Lewis Seeing Jayce was mad at God for making him that way, the poor mother felt it a huge dagger to her heart. What made her more sorrowful was that she didn’t know what to do at that point and how to provide answers to her son’s questions which she could never find out herself. The white lie burst just like bubbles that day.

A few weeks later, Lewis turned on the TV to a news story, where she was shocked to find out the answer. It was Trashaun, an eighth grader, that displayed positive energy from his head to his toe. The 14-year-old sunny boy performed his slam dunks(大灌篮) on the TV, who had been a hit on the Internet. However, like Jayce, he had missed most of his left arm since his childhood! Lewis called her son Jayce in. The poor little boy got spellbound, watching dunk after dunk.

At the time, it seemed that watching Trashaun would simply be an inspiring moment for Jayce. He saw Trashaun as a tough role model who had a seemingly similar born disability but led a brilliant life. And had it stayed just that, Lewis would have been happy. But little did she know that a family friend had already reached out to Trashaun, asking him to help set up a meeting with Jayce to rebuild his confidence.

2 . Dogs feel their way through the world with their noses. Researchers have started imitating this super skill with an artificial-intelligence-based detective tool. In a study published in February in PLOS ONE, a multinational team reported an AI-powered system that is as accurate as trained dogs at correctly identifying cases of prostate cancer from urine samples. Andreas Mershin, a research scientist from Massachusetts Institute of Technology, wants to eventually integrate the technology into smartphones: There would be a tiny sensor in the phone with AI software running in the cloud.

Prostate cancer, the second most deadly cancer in men worldwide, is difficult to detect. The most widely used test can miss 15 percent of cancers. Trained dogs, on the other hand, were able to identify patients with prostate cancer from urine samples more than 96 percent of the time. Yet dogs can get bored and tired, so researchers want to develop an AI system that works more consistently.

Living cells produce chemicals that come out from the skin, blood, urine and breath. Artificial noses, including the "Nano Nose" that Mershin and one of his colleagues developed, can already detect those chemicals at the same parts-per-billion concentration as dogs. The team added to the chemical sensing an artificial neural network—a type of AI algorithm that can learn from looking at examples how to identify faces, for instance.

As the 2015 Journal of Urology study showed, dogs can be trained to reach more than 96 percent accuracy, and the AI can be trained to reach that same rate. Mershin plans to train the AI algorithm using data from the "Nano Nose", which is currently one third the size of an iPhone 10 and could be further shrunk to be integrated into smartphones.

4 . People often want to simplify their lives. It is a lot of stress to have a complicated life, full of schedules, meetings, possessions, and so forth. Usually, a simpler life translates to less anxiety, stress and worry.    1    Follow the step-by-step process below to bare down your lifestyle piece by piece.

First, get rid of all the possessions you haven't used in the last year. If you haven't put a thing to use in one year, it is probably not worth keeping.    2     Put anything you haven't used in one year in that bag. Next, manage your social media and electronics usage. We usually spend more time on our devices than we imagine. These days, people can spend the majority of their days on social media and electronic devices. These all-in-one devices are great tools.    3    

On a deeper level, we can simplify our thinking. Most of our thinking is not necessary.    4    If you do not want to go that far, try to ignore the thoughts that are not related to the present. A continuous stream of thoughts is not necessary. Sure, some planning should be done for the future, but there is no need to overthink.

    5    We can get rid of possession's that are non-essential, manage our social media and electronics usage, and also clean up our thinking so that we are more in the present and do not engage in unnecessary worry, or anxiety. All these things take energy and time, of which we have only have a limited amount.

A．No thought is important.

B．Get rid of electronic devices'

C．So, how do we simplify our lives?

D．Is planning our thoughts effort-making?

E．Simplifying our lives is a complex task.

F．But they should not become the main focus of our life.

G．Get a big garbage bag and walk around your living space.

5 . Delivering medical supplies to hard-to-reach places has been an issue for years. Worldwide, more than two billion people lack access to essential life-saving supplies, such as blood and vaccines（疫苗）. In the African nation of Rwanda, for example, several remote health clinics do not have sufficient quantities of blood and other healthcare products. A company called Zipline is trying to address this problem. It uses drones（无人机）to transport medical supplies around Rwanda. A drone can now deliver medicine in 30 minutes.

Drones are also assisting emergency organizations after natural disasters. In 2015, for example, a powerful hurricane destroyed thousands of buildings in the Pacific island nation of Vanuatu. Around 75,000 people lost their homes, and at least 15 died. After the storm, drones photographed the damage. These surveys helped emergency workers assess the situation quickly and answer important questions: Which areas were hardest hit? Were crops damaged? What roads were affected?

Drones are also helping to protect wildlife populations in parts of Africa and Asia. Every year, poachers（偷猎者） kill thousands of elephants, rhinos, and other endangered animals. To stop them; the environmental organization World Wildlife Fund is using drones to find where poachers are hiding and if they are carrying weapons. Equipped with infrared video cameras, drones can easily identify people and animals at night. These drones are not only helpful, they are affordable.

As well as finding poachers, drones can be used to track animals. Scientists at Liverpool John Moores University （LJMU）plan to employ drones for an ambitious conservation project: documenting the world's wildlife. The long-term project will start with scientific surveys of animal populations. And animal species can then be identified using special software.

Ironically（讽刺地）, a tool originally created for military use is increasingly being used to save lives instead of taking then. Drones have the potential to provide solutions that will benefit both humans and animals.

1. What does the text focus on?

A．Importance of saving lives.

B．Development of drones.

C．Applications of drones.

D．Ways to protect animals.

2. What can drones be used for according to Paragraph 2?

A．Helping predict disasters.

A．Track poachers.

B．Design new practical drones.

C．Record wild animals in detail.

D．Develop an assessing software.

4. What can be inferred about drones?

A．They need to be fitted with video cameras.

B．They are unavailable to ordinary people.

C．They should be limited to military use.

D．They have a promising prospect.

9 . If you were to throw, say, a banana peel out of your car while driving along the motorway, that would be a completely harmless action, due to the fact that it’s part of a fruit — right? Actually, no. A banana peel can take up to two years to be naturally processed, and with a third of motorists admitting to littering while driving, that’s a whole lot of discarded banana peels. An orange peel and a cigarette butt has a similar biodegrading (生物降解) term to that of a banana peel, but tin cans last up to 100 years; and plastic bottles last forever, as do glass bottles.

Despite the fact that longer-lasting materials will serve to damage the environment and its animals for longer, we can’t merely measure the severity of a certain type of rubbish by its lifetime. For example, despite having a fairly short length of biodegrading time, more than 120 tons of cigarette-related litter is discarded in the UK every day.

It’s not a cheap habit either: to keep our streets clean annually costs UK taxpayers £500 million, and when you include our green spaces, that goes up to £1 billion. So, it’s not surprising that if caught fly-tipping you could face a £20,000 fine or even jail time and, if you disposed of something dangerous, the court could give you five years to serve. Regardless of how severe these punishments might seem, however, among the reported cases only 2,000 were found guilty out of 825,000, so we still have some way to go in making sure people obey the rules.

1. What does the underlined word “discarded” in para1 mean?

A．Harmless.

B．Processed.

C．Thrown.

D．Long-lasting.

2. Which of the following has the longest biodegrading term?

A．Glass bottles.

B．Tin cans.

C．Cigarette butts.

D．Banana peels.

3. What can be inferred from the passage?

A．The severity of rubbish can be measured by its lifetime.

B．Quite a few people were found guilty of illegally littering.

C．Every year UK taxpayers spend £500 million keeping streets free of dirt.

D．Cigarette-related litter and peels can be ignored for their fairly short lifetime.

4. What is the purpose of the passage?

A．To inform readers of different biodegrading terms.

B．To call for people not to litter illegally.

C．To encourage people to use fewer plastic bags.

D．To stress the importance of good behavior.
