When Gitanjali Rao was 11， she invented equipment that quickly tests lead in water. She became the youngest ever winner of the Discovery Education 3M Young Scientist Challenge.

In 2016， the news was full of stories about dangerous drinking water in Flint， Michigan. The water had too much lead in it. Lead is a metal that can cause health problems when people eat or drink it.

There was home test equipment that could detect lead in water. But these tests didn’t work very well. They took too long and often gave wrong results. Gitanjali wondered if she could create a test that was quick， easy， and right.

One day， Gitanjali read a news story about using carbon nanotubes (納米管) to test for poison in the air. The nanotubes were coated with a chemical that stuck to the poison. When the poison stuck， it changed the way electricity flowed through the tubes. Scientists could measure the electric flow to see how much poison was in the air. Gitanjali wondered if she could use the same way to detect lead in water.

She e-mailed a chemistry teacher at her local school. They didn’t have a fancy lab， but it was good enough for Gitanjali to test whether her detector could sense lead at all. They started by testing clean water. The electricity meter (電表) jumped all over the place. Gitanjali learned how to adjust it. Next they added tiny spoons of lead. After many， many tries—her detector worked.

Then Gitanjali made a phone app so users could use the results at once on their phones. She entered her idea in a big national competition. When she was picked for the semi-finals， she was assigned an advisor to help her work on her equipment. And—she won!

Gitanjali’s next goal is to sell her equipment in stores and make versions that test for different kinds of pollution. She is also very interested in genetics (遺傳學(xué)).

24. What can we know about the home test equipment from Paragraph 3?

A. It’s quick. B. It’s expensive. C. It’s time-saving. D. It’s inaccurate.

25. Where did Gitanjali get the inspiration of her invention?

A. From the news story she read. B. From a chemistry teacher.

C. From a chemistry lesson. D. From the 2016 news.

26. What does the underlined word “it” in Paragraph 5 refer to?

A. The place. B. Her detector. C. The quantity of lead. D. The electricity meter.

27. What words can best describe Gitanjali?

A. Determined and creative. B. Hard-working and outgoing.

C. Confident and devoted. D. Energetic and honest.

The early life of the green sea turtle is full of danger. Only one in 1，000 baby sea turtles survive to adulthood. From its home in the sand， it breaks its egg with an egg tooth. Its mother is not there to help it. Instead， it is greeted by crabs， coyotes， and dogs waiting to eat it for dinner. To survive， the baby turtle must hide in the sand until night. Then， it moves slowly to the sea.

The small turtle must swim hard to reach the ocean waters. In the sea， it tries hard to find food. It must also keep itself from being food for fish.

As dangerous as the sea turtle’s life is in the natural world， its most dangerous enemies are humans. The rubbish left by humans in the ocean causes problems for the small green sea turtle. A little turtle might eat a piece of plastic in the sea. It might also eat oil on the ocean’s surface. Young turtles also get caught in fishing nets. There are laws against hunting sea turtles. Still， many are hunted， both for their meat and for their shells. All of these dangers must be prevented.

Sea turtles that do survive to grow into adulthood go through many changes. For example， adult green sea turtles weigh about 500 pounds. They stop eating jellyfish and other meat and eat only plants. And they may plan a trip to go back home again. A mother sea turtle goes back to the beach where she was born. This is the only place where she will lay eggs. Even if it has been forty years since she was a baby， she always knows her way back home.

28. Why do baby turtles move to the sea at night?

A. They dislike sunshine. B. They need to avoid enemies.

C. They can find food easily then. D. They prefer lower temperatures.

29. What does the author think of the young turtles in Paragraph 3?

A. Pitiful. B. Careless. C. Interesting. D. Courageous.

30. What can we learn about sea turtles from the last paragraph?

A. They mainly feed on fish and meat. B. They can live for about 40 years.

C. They produce eggs at their birthplaces. D. They visit their beach homes every year.

31. What is the text mainly about?

A. The homes of green sea turtles. B. How sea turtles find their food.

C. The dangers faced by sea turtles. D. How young turtles become adults.

A robot created by Washington State University (WSU) scientists could help elderly people with Alzheimer’s Disease (阿爾茨海默病) and other limitations live independently in their own homes.

The Robot Activity Support System， or RAS， uses sensors (傳感器) installed in a WSU smart home to determine where its residents are， what they are doing and when they need assistance with daily activities. It positions through rooms and around obstacles (障礙) to find people on its own， provides video instructions on how to do simple tasks and can even lead its owner to objects like their medicine or a snack in the kitchen.

“RAS combines the convenience of a mobile robot with the activity detection technology of a WSU smart home to provide assistance in the moment， as the need for help is detected，” said Bryan Minor， a postdoctoral researcher in the WSU School of Electrical Engineering and Computer Science.

Currently， an estimated 50 percent of adults over the age of 85 need assistance with everyday activities such as preparing meals and taking medicine and the annual cost for this assistance in the US is nearly $2 trillion. Researchers hope that technologies like RAS and the WSU smart home will make it easier for older adults to live alone.

RAS is the first robot researchers have tried to include into their smart home environment. They recently published a study in the journal Cognitive Systems Research that demonstrates how RAS could make life easier for older adults struggling to live independently.

“While we are still in an early stage of development， our initial results with RAS have been promising，” Minor said. “The next step in the research will be to test RAS’ performance with a group of older adults to get a better idea of what prompts， video reminders and other preferences they have regarding the robot.”

32. What does RAS serve elderly people with?

A. Sensors. B. Smart objects. C. A mobile robot. D. A detection system.

33. What can we learn about RAS?

A. Its users are those over 85. B. Its function remains to be tested.

C. It is the first robot used in daily life. D. It can locate people and do complex tasks.

34. What is Minor’s attitude toward the future of RAS?

A. Doubtful. B. Critical. C. Positive. D. Unconcerned.

35. What is a suitable title for the text?

A. RAS， the First Robot to Make Home Smart B. Older Adults Will Benefit from RAS

C. Elderly People Leave the Nursing Home D. WSU Tests First Elder-Care Robot

Cities are getting bigger， busier， and more crowded. Removing road traffic completely is almost impossible. 38 For example， public agencies use data insights to map out regular routes， create other routes in case something goes wrong.

Entertainment

The entertainment services we use every day， such as music and video streaming apps， are largely designed on the basis of big data. 39 At a higher level， big data helps entertainment production houses predict the kind of shows that viewers from different age groups want so that they can create favored content.

Finance (金融)

In the past financial services such as insurance and banking were built on an inflexible， one-size-fits-all mode， which meant not only people with low credit scores were rejected in some ways， but also clients couldn’t get what they needed. 40

Big data has influenced many other sectors as well， like agriculture， science， education， and manufacturing， and it remains to reveal its full potential (潛能) in the future.

A. And this gives rise to big data.

B. A process like this is known as big data analytics.

C. But big data is able to assist in keeping it under control.

D. These platforms use data to discover what customers like most.

E. Now big data has made it easier to offer proper services to them.

F. It refers to a large amount of data that come in various forms sources.

G. The coming of big data analytics has influenced our lives in many ways.

China is leading the world in facial recognition algorithms (人臉識別算法). It is reported that its best algorithm can recognize 10 million people 61 a single mistake in less than a second.

The top five of the 39 facial recognition algorithms in the world come from China， according to a test， 62 released the results last Friday. YITU Technology， 63 Shanghai-based company that claimed both the top and second spot on the list， said that its top algorithm is able 64 (recognize) nearly every person in a sample base of 10 million. However， “it is very likely for a human brain to make 65 (mistake) in recognizing the identities (身份) of 100 people，” the company said. Algorithms from Beijing-based company Sense Time 66 (win) the third and fourth spot， while the Shenzhen Institutes of Advanced Technology (SIAT) claimed 67 (five) in the test. YITU said that higher facial recognition accuracy means that users gain 68 (good) experiences when 69 (use) related products. For example， when a user uses facial ID for payment on a smartphone， it will not authorize the payment for someone else with a similar 70 (appear) as the user， the company noted.
