Senior citizens are permitted to travel cheaply on a bus if they have a special card. Women may get cards when they are sixty.

Mrs. Matthews lives in the country but she went into town once a week to buy food and other things for the house, and she usually went by bus. She always had to pay the full price for her ride.

Then she reached the age of sixty and got her senior citizen’s card, but when she used it for the first time on the bus, it made her feel very old.

The bus driver had often seen her traveling on the bus before, and he notices that she was feeling unhappy, so after she had paid her money, he winked(眨眼)at her and whispered, “Don’t forget to give your mother’s card back to her when you see her again.”

Mrs. Matthews was very happy when she heard this.

As I walked into the drugstore to pick up a roll of toilet paper and cat food the week of Halloween, I found myself being stared down by an oversized Rudolph doll. His eye expression aroused a swell of anxiety within me. This is not because I have an irrational fear of dolls. The red nose is a mocking reminder that for those of us who are members of dysfunctional(功能失调的) families, the most wonderful and challenging time of year is upon us. The issue isn’t that the holiday season brings a new, once-a-year, unpleasant feeling. Rather, this time of year enlarges the most complicated, sensitive area of my life: family.

Over the past several months, certain situations have left me emotionally raw when dealing with the subject of family, particularly my mom. The holiday season has never agreed well with her, physically or emotionally. Her first heart attack took place two weeks before Christmas when I was in the seventh grade. The song “Jingle Bell Rock” instantly took me back to driving to the hospital to visit her after her emergency heart operation. When I was at grade 2 at high school, we found ourselves awkwardly putting turkey into our mouths after my mom had come from a week-long stay in the hospital to recover from heart attack and a stroke. A girl of 15, due to the gift of having my mom alive and home to celebrate, my heart was contradictory that Thanksgiving.

2.By saying the holiday season has never agreed with her, the author wanted to show ________.

A. her mother was not comfortable on holidays

Imagine having an idea, drawing it on paper, bringing it to a store and seeing it turned into a

physical object. This is now possible with the help of 3D printers. Such machines were once used just

by universities and big companies, but now, stores with 3D printing services are appearing around the

United States.

Bryan Jaycox and his wife opened The Build Shop LLC in Los Angeles two years ago. The store

is filled with tools like a laser cutter, an industrial sewing machine and 3D printers. The Jaycoxs offer

3D printing classes and services for anyone who is interested.

"I think 3D printing is going to be huge. It's going to have a huge effect on society as a whole."

One of the students in a recent class was KiChong Tran. He plans to open a 3D printing business in

Cambodia.

3D printing services are becoming available for American consumers.

The UPS Store is a nationwide retailer (零售商 ) that provides shipping, copying and other

services. The UPS Store recently put 3D printers in three of its independently-owned stores. Burke

Jones owns one of the stores in San Diego.

"The demand has been amazing. It's been much more than I would have imagined." The UPS

Store plans to add 3D printers in three more stores.

At The UPS Store, the cost of the object depends on the amount of materials used. The store

charges up to $95 an hour to design the object with computer software that creates a digital file to

guide the printer.

Mr. Jaycox predicts that within five years, 3D printing technology could become more popular.

But KiChong Tran says even current technology can make a difference in a developing country like

Cambodia.

"With 3D printing, you can give them tools; you put it in their hands so they are responsible

more for their own development and they learn skills beyond just learning English and becoming a

tour guide or something like that or working at a bank; you can actually create things that give value

to the world."

He says it's not just in Cambodia but anywhere where there is a 3D printer that it can turn a good

idea into reality.

1.The purpose of the passage is to _

A. attract consumers to buy 3D printers B. explain the importance of 3D printing

C. introduce a new technique-3D printing D. describe the rapid development of technology

2.The Build Shop LLC is a store .

A. promoting 3D printers B. offering 3D printing classes and services

C. selling sewing machines D. known for tools like laser cutters

3.At the UPS Store, the price of a 3D object depends on

A. the person who makes it B. the materials to make it and time to design it

C. the size of the object D. the labor service it needs

4.The attitude of KiChong Tran towards the development of 3D printing technology is

A. positive B. objective C. uncertain D. critical

Artificial intelligence can ide ntify skin cancer in photographs with the same accuracy as trained doctors, say scientists. The Stanford University team said the findings were "incredibly exciting" and would now be tested in clinics. Eventually, they believe using AI could revolutionize healthcare by turning anyone’s smart-phone into a cancer scanner.

The AI was repurposed from software developed by Google that had learned to spot the difference between images of cats and dogs. It was shown 129,450 photographs and told what type of skin condition it was looking at in each one.

It then learned to spot the hallmarks of the most common type of skin cancer: carcinoma, and the most deadly: melanoma(黑色素瘤). Only one in 20 skin cancers are melanoma, yet the tumor(肿瘤) accounts for three-quarters of skin cancer deaths.

The experiment, detailed in the journal Nature, then tested the AI against 21 trained skin cancer doctors. One of the researchers, Dr Andre Esteva, told the BBC News website: "We find excitedly, in general, that we are on par with excellent skin cancer doctors."

However, the computer software cannot make a full diagnosis, as this is normally confirmed with a tissue biopsy(活检). Dr Esteva said the system now needed to be tested alongside doctors in the clinic. "The application of AI to healthcare is, we believe, an incredibly exciting area of research that can be leveraged to achieve a great deal of societal good," he said. "One particular route that we find exciting is the use of this algorithm on a mobile device, but to achieve this we would have to build an app and test its accuracy directly from a mobile device." Incredible advances in machine-learning have already led to AI beating one of humanity's best Go players.

And a team of doctors in London have trained AI to predict when the heart will fail.

1.From the passage we can infer that ________.

A. Artificial Intelligence must replace human one day

B. we can use Artificial Intelligence to cure skin cancers

C. we can use smart-phone to scan our skin at present

D. the research will be of great help to us and our health care

2.Which one will he agree with according to Dr Esteva?

A. Artificial Intelligence has beaten all of humanity’s best Go players.

B. Artificial Intelligence could support assessments by GPs.

C. We still need professional doctors with the help of the system.

D. There are too many disadvantages for Artificial Intelligence.

3.The underlined words “on par with” in Para 4 likely mean ________.

A. inferior to B. equaled by C. superior to D. opposite to

4.What’s probably the best title of this passage?

A. Cancer Doctors Are Out

B. An APP Scanning Skin Cancers

C. Artificial Intelligence—change our future

D. Artificial Intelligence—as good as cancer doctors
