Staying Motivated When Studying
Some people say that the hardest step in studying is to get started. Other people, however, find it difficult to stay motivated, especially when the end seems a long way away. This situation arises. There is no single strategy that will work for everyone. However, 1. and you can see if they work for you in supporting ongoing motivation.
Keep your end goal in mind
One of the best ways to stay motivated is to remember why you are studying in the first place. “Getting good exam results” is not necessarily very motivating. Instead, you need to look beyond that to what the exam results will get you,2. The more detail you can provide for your goal, the easier it will be to keep in mind.
Get into a study routine
It is generally easier to stay motivated if your studying becomes part of your everyday life. For example, you might choose to get up an hour earlier, and spend that hour studying each day. That way, 3., because you know that it is set aside for a purpose. Your friends and family will also get to know when your study time happens, and hopefully avoid you then.
4.
Especially when you first start studying, you will not necessarily know what works for you. It is therefore worth trying different ways of doing, to see which you find most productive. You may find it helpful to vary your style of working. You could, for example, try working in different places. You could also try different types of activities. Options include reading over your notes, writing a mind map, making up songs or poems to help you remember facts.
5..
There are plenty of people to tell you that they have the answer to staying motivated while studying.They may have the answer for them, but only you can work out the answer for you.
A.There is no “one size fits all”
B.Try various study approaches
C.Break the task down into different parts
D.there are plenty of options that you can try
E.it is easier to avoid being distracted during your study time
F.A system of short-term goals and suitable rewards may be needed
G.whether that is a place at your chosen school or university, or a new job
In recent years, the leaders and islanders of many small-island nations have warned that climate change is an existential threat to their homelands, fearing they could disappear under rising seas as the planet warms. But according to the latest research, small, low-lying islands dotted around the Pacific and the Caribbean—often seen as the places most vulnerable to global warming—can naturally adapt and raise themselves above disturbing waves.
A three-year study led by Britain’s University of Plymouth, which looked at coral reef islands such as the Maldives, found that tides move sediment (沉积物) to create higher altitude, a process that may keep islands habitable. These islands were formed hundreds of thousands of years ago by waves moving and piling up reef material or sediment to create higher ground—a natural defence mechanism that continues.
Low-lying island states are judged to be at greatest risk from increasingly powerful storms and rising oceans, with some making preparations to resettle their people within decades. Many are already building sea walls, appealing for international aid or setting up projects to repair damage caused by climate change impacts. The world’s tens of thousands of coral reef islands are mostly uninhabited, but are home to about one million people who largely rely on fishing or tourism for a living.
Scientists built a model coral reef and island in a laboratory tank with rising water levels and used computer models to reproduce how such islands respond to higher seas in reality. The results suggest that by choosing climate-adaptable infrastructure (基础设施) that allows for occasional flooding, like building on stilts (桩子) and movable houses, islanders with enough space could adapt to their shifting environment. Sea walls, however, are compromising the natural ability of the islands to adjust to rising sea levels. “If you stop the flooding of the islands, you also stop the movement of the sediment on top of the island,” said lead author Gred Masselink, professor of coastal geography at the University of Plymouth.
1.What does the underlined word “vulnerable” in Paragraph 1 probably mean?
A.Unnoticeable. B.Beneficial.
C.Significant. D.Sensitive.
2.What do we learn from the three-year study?
A.Piling-up sediment creates a natural defence for small islands.
B.Disturbing waves keep the islands unlivable.
C.A computer model is used to provide more space for islanders.
D.Sea walls prevent the disappearance of small islands.
3.Which word best describes low-lying island states’ attitude to rising seas?
A.Casual. B.Joyful.
C.Unconcerned. D.Defensive.
4.What is the best title for the text?
A.Small Islands May Not Disappear Under Rising Sea.
B.Climate Change Poses Threats to Small Islands.
C.The Climate-adaptable Infrastructures of Small Islands.
D.The Perfect Solution to Rising Seas for Small Islands.
As artificial intelligence (AI) systems become more subtle, we can expect them to be used more often in the world of human medicine and healthcare. AI is designed to imitate the human brain in decision making and learning, so with the computing power to learn tasks in days or even hours, it is possible to create medical AIs that rapidly outperform doctors in certain tasks.
Most of the AI systems working in medicine employ smart algorithms ( 算 法 ), with the machine and deep learning techniques, and are supported by speech recognition and computer or machine vision to make their decisions. It will be some time before researchers can develop artificial general intelligence systems capable of abstracting knowledge and developing their own experiences to share with other AIs. But firms like Microsoft, Google, Apple,
IBM and Facebook are preparing themselves up to deliver the most advanced AI personalized healthcare possible for patients around the world.
Data plays a hugely important role in helping AI systems learn about human medicine. AI systems are trained on large data sets gathered from real-life cases. Providing amounts of detailed patient information is a decisive factor for their success.
One of the most important areas for influencing global health is in the field of epidemiology ( 流行病学).
Predicting disease outbreaks can save millions of lives by having resources ready should the worst happen. Another field where medical AIs are making rapid advances is in diagnostics. Doctors base a lot of decisions on information from X-ray, CT and MRI images. Speeding up diagnoses from patient scans can rapidly improve patient care and outcomes.
Cardiologist (心脏病医生) Rima Arnaout developed an AI that beat human experts at correctly interpreting echocardiograms by 92 percent to 79 percent. She said that despite the result there is no hope of AI replacing human doctors any time soon. "As cardiologists, we read the images and then go see the patient," she said. "So we’re both reading images and practicing medicine. I don't think that the second piece will be taken over so quickly."
1.The purpose of this text is to introduce ________.
A.the speech recognition of AI systems
B.the computer vision of AI systems
C.the rise of AI systems in medicine
D.the development of AI in tech firms
2.What is the key to making medical AI systems successful?
A.Arriving at decisions.
B.Providing patient data.
C.Predicting disease outbreaks.
D.Speeding up diagnoses.
3.What can we infer from Rima's words?
A.She prefers practicing medicine to reading images.
B.AIs do better than cardiologists in seeing patients.
C.She is confident in the irreplaceable role of human doctors.
D.AIs are unable to read images with current technology.
