【題目】How AI Protects Us

We should consider AI not as something competing with us, but as something that can strengthen our abilities. 【1】 And it might help keep us safe in the 21st century.

Predict infectious (傳染性的) diseases

The AI in medicine is a system that combines the time and location of each new infectious disease. “These are all factors that determine how the disease will spread,” explains a researcher. 【2】 It will allow public health officials to take action early for locals.

Keep hunger from the door

Researchers develop an automated system aimed at fighting against diseases in crops. The Mcrops project allows local farmers to take pictures of their plants and use computers that have been trained to spot the signs of the four main diseases that are responsible for damaging crops. 【3】

Fight cancer

Cancer causes more than 8.8 million deaths worldwide and 14 million people are diagnosed with some form of cancer every year. 【4】 Now Google and IBM have been applying their AI technology to this problem.

【5】

The task of balancing power supplies is getting harder. The spread of smart meters — digital energy monitors that automatically record usage - is also providing more data than ever about how and when consumers use energy. The EU alone plans to have 500 million smart meters in homes by 2020.

A.Record the locations smartly.

B.Keep the balance of power supplies

C.Thus, the farmers can have a good harvest.

D.The system can also help to predict the disease.

E.This is because AI has an ability that’s far beyond humans.

F.But now people have no ideas how to deal with the terrible problem.

G.Yet catching cancers as early as possible can greatly improve a patient’s chances of survival.

【題目】 If our bodies actually suffer from eating too much sugar, then why do we like it? And why don 't we have such a strong eager for food like, say, broccoli (西蘭花)，which is a great source of Vitamin C,Vitamin K iron, all things our body actually needs? If it's so bad for us, then why does sugar taste so good? There are hundreds of journal articles trying to answer that very question. Let' s take a look at what they' ve come up with.

Studies have shown that the love children have for sugar may be born with. In other words, kids may have a built-in love of all things sweet. The preference for sweet foods is found to be already evident in newborns, who prefer sweeter formulas (配方). It also seems to be shared by children globally across cultures and climates. There’s further evidence that kids’ taste buds (味蕾) are more sensitive to bitter-tasting foods, further pushing them to reach for the sweets. One study showed that adults tend to maximize their sugar preference at about the level of sugar in a can of soda, but older children still liked drinks that were twice as sweet. The scientists couldn't find a limit to the concentration of sugar younger children preferred. It turms out that the kids still liked the sugary drink even past the point where there was too much sugar to be dissolved (溶解) in water anymore.

Sugar gets a bad fame, but it isn't all bad. Sugar provides our bodies with calories, which we can then change into energy. Children, in particular, need this energy to fuel their rapid growth. Sugar also helps us store fat, which can be drawn on later if needed. Our body knows to pursue the things it needs as two way of signaling our brain to start eating what we’re missing.

As a vegetarian (素食主義者)，I know that when I start thinking about stealing the peanut butter sandwich that's been floating around in my kid' s backpack, it' s probably not because the sandwich is so delicious. It' s more likely that I haven't gotten enough protein for the day.

【1】What makes so many people study sugar?

A.High sugar intake.

B.Curiosity about Sugar.

C.The love for sugar.

D.The magic effect of sugar.

【2】What do the studies show about eating the sweets?

A.Loving sugar is human's nature.

B.A vegetarian doesn't like sugar so much.

C.The older one is, the more sugar one needs.

D.The love for sugar depends on living habits.

【3】How does sugar impress us according to the text?

A.Deadly but irresistible.

B.Beneficial but harmful.

C.Necessary but not welcome.

D.Useful but not nutritious.

【4】Why does the author steal his kid's food?

A.To store more protein,

B.To treat his illness.

C.To avoid his kid eating more.

D.To meet body' s needs.

【題目】On March 17, people around the world celebrate the Irish holiday of Saint Patrick’s Day. It is a major holiday in Ireland, but the rest of the world has influenced its celebration as much as the Irish themselves.

Most Americans think of Saint Patrick’s Day as a big party centered around drinking alcohol. But its beginnings in Ireland were religious, says Mike Cronin, a professor of Irish history with Boston College of Massachusetts.

Ireland is a mostly Roman Catholic country. Saint Patrick lived in Ireland more than 2,000 years ago. He is widely considered to have established Christianity in the country. The Church honored him with a holy day in the 17th century. March 17 marks the date of his death. The average Irish person honored March 17 quietly. Attending church services was the main activity. In fact, most businesses that served alcohol would close in honor of the day.

In the early 1900s, Ireland’s government made St. Patrick’s Day an official holiday. By the 1960s, towns across Ireland started celebrating the holiday with parades and music. In Ireland today, St. Patrick’s Day is a four-day public celebration that includes parades, music, food, and games.

For Irish people living outside Ireland, Saint Patrick’s Day became a chance to celebrate their Irish identity and culture. Now, countries and cities around the world celebrate March 17 in creative ways. Many countries hold Saint Patrick’s Day parades. Famous monuments, including the Great Wall of China, the Niagara Falls, and the Gateway of India in Mumbai will all be colored by green light for the day.

Cronin says that the worldwide popularity of Saint Patrick’s Day has helped the Irish government, which uses the holiday as a form of diplomacy. And for a small island of 4.5 to 5 million people it’s quite remarkable that they have that kind of soft power.

【1】How did average Irish people celebrate Saint Patrick’s Day in the 17th century?

A. Drinking alcohol. B. Parading in the streets.

C. Attending church services peacefully. D. Coloring well-known monuments green.

【2】What can we learn from the passage?

A. Saint Patrick’s Day is the most significant day in the US.

B. Saint Patrick’s Day plays a role in foreign affairs in Ireland today.

C. Saint Patrick’s Day is celebrated worldwide today as in the 17th century.

D. On Saint Patrick’s Day, parades and parties are held throughout America.

【3】What is the passage mainly about?

A. The origin of Saint Patrick’s Day.

B. The celebration of Saint Patrick’s Day.

C. The influence of Saint Patrick’s Day on the world.

D. The role of Saint Patrick’s Day in Irish diplomacy.

【4】What is Cronin’s attitude towards the popularity of Saint Patrick’s Day?

A. Unclear. B. Neutral. C. Negative. D. Positive.
