Tests have shown robots can diagnose heart problems in as little as four seconds, as a review of artificial intelligence （Al） finds machines are now as good at spotting illness as doctors.
Analyzing a patient's heart function on a cardiac MRI （心脏磁共振成像）scan currently takes doctors around 13 minutes. But a new trial by University College London （UCL） showed an Al program could read the scans in less time with equal accuracy. There are approximately 150,000 such scans performed in the UK each year, and researchers estimate that fully using Al to read them could save 54 clinician-days （临床天数）at each cardiac centre per year. So it can make up for the shortage of doctors.
It is hoped that Al where computer systems are able to learn from data to identify new patterns with minimal human intervention will transform medicine by helping doctors spot dis- eases such as heart disease and cancer faster and earlier. However, most scans are still read by specially trained doctors.
Dr Charlotte Manisty, who led the UCL research, said, "Cardiovascular MRI offers in- comparable image quality for assessing heart structure and function. However, current manual analysis remains basic and outdated. Automated machine techniques offer the potential to change this and completely improve efficiency and accuracy, and we look forward to further research that could confirm the superiority to human analysis."
She added, “Our dataset of patients with a range of heart disease who received scans enabled us to demonstrate that the greatest sources of measurement errors arise from human factors. This indicates that automated techniques are at least as good as humans, with the potential soon to be 'super-human'—transforming clinical and research measurement precision."
Professor Alastair Denniston said, "Within those handful of high-quality studies, we found that by deep learning Al could indeed detect disease ranging from cancer to eye disease as accurately as health professionals. But it's important to note that it did not absolutely exceed human professional diagnosis. ”

4.What is the main idea of the text?
A.Al has many shortcomings in practice.
B.Al totally shows its superiority to human analysis.
C.Al can reduce medical errors arising from human factors.
D.Al can diagnose heart disease as well as doctors in less time.
You should try your best to create your own family library so that you and your family are always learning. "It is a great mistake to think that education is finished when young people leave school. Education is never finished even if you grow older," said Mrs Child in The Mother's Book. "Collecting a library of books in your home is really helpful to your family. ”
"What is really interesting about having so many books in your home is that a book you purchase has a chapter about the deeper knowledge of your favorite subject at school," said a university graduate. Researchers in a study tries to identify what parents do has an influence on how well their children do on standardized tests. One positive aspect they find is the availability of a large number of books at home. This has a stronger connection, especially when you read to your children every day. The more books your older kids have access to at home, the more likely they are just to be reading for fun, rather than having to wait for weekly trips to the library.
John Henry, one educated parent, said, "I have been homeschooling my children using the philosophy of A Thomas Jeffer son Education. This philosophy of learning is based on the reading of classic books. ” Clinton Fadiman said, "When you reread a classic, you do not see more in the book than you did before； you see more in you than before. " Classic books also make you smarter and wiser! The wisdom comes in the examples in the lives of the characters.
"It is within your power to guide your youth in their reading and to cultivate in their hearts a desire for good books. It is the most unfortunate if a person is not possessed with the desire for good reading. The reading habit, like charity, should begin at home," said Mrs Child.

2.How does the author explain the effect of reading classic books at home in paragraph 3?

3.What can we learn from what Mrs Child said?
A.East or west, home is best.
B.One is never too old to learn.
C.He who makes no mistakes makes nothing.
D.Charity is the soul, rather than the virtues of hand.
4.What can be the best title for the text?
A.Where to Store Your Favorite Books at Home?
B.When to Read the Classic Books to Your Children?
C.Which Is Better, a Home Library or a Public Library?
D.Why Not Have Your Own Library of Books at Home?
As I drove along the road, a small car flew across the center divider from the opposite direction and crashed into my car head-on, I fainted and was awakened by the ringing of my mobile phone.
I was brought to Kuala Lumpur General Hospital bleeding on from my nose, mouth and legs. But the hospital staff was too busy to attend to me, so I called a friend to tell him about the accident. Some friends arrived very soon and sent me to a private hospital nearby. I saw my injured feet hanging from my body, blue and lifeless, and I begged the doctors to save them at all costs. They calmly promised to do their best.
The doctors made it. After I was discharged, I was given ten months medical leave. My heart sank, knowing that it meant I, a big man, couldn't work. How was I going to support my 65-year-old mother and other family members? I felt completely helpless, but a lot of unexpected blessings came my way. I had many visitors during my 14 days in hospital and when I was recovering at home. Friends and relatives helped me with my banking, insurance or simply came to cheer me up.
When the casts （石膏）were removed, I did not let the sight of my weak legs discourage me. I worked hard at my physiotherapy （物理疗法）with only one aim. After eight months, I was walking without the aid of a walking stick. On February the following year, I returned to my job again. Today, after eight years, I have travelled to many countries as a tour leader.
The accident makes me realize how lives can change in a split second. I value life more, not only of my own but also of everyone I know, and I will always try to help when I know of someone in trouble.

There was a time when I was addicted to online games. Because of that, my study was suffered a lot. Instead for scolding me, Mother gave me a book by Helen Keller and asked me to read it. Hardly have I finished a few pages when I was great attracted by Helen Keller. Despite her disability, she didn’t abandon hope and achieve a lot. This was her determination and courage that made her huge success.
When I finished reading the book, Mother had a talk with me. “You can also accomplish which Helen Keller did.” Mother’s words ring in my ear whenever I see the book, inspired me to face challenges in life.
