1 . It was a cold evening and my daughter and I were walking up Broadway. I didn't notice a guy sitting inside a cardboard box. But Nora did. She wasn't even four, but she _______ at my coat and said, “That man's cold. Daddy, _______ we take him home?”

I don't remember my reply. But I do remember a sudden _______ feeling inside me. I had always been delighted at how much my daughter noticed in her _______, whether it was _______ in flight or children playing. But now she was noticing _______ and beggary.

A few days later, I saw an article in the newspaper about volunteers who picked up a food package from a nearby school on a Sunday morning and _______ it to an elderly person. It was quick and easy. I _______ us up. Nora was _______ about it. She could understand the importance of food, so she could easily see how ________ our job was. When Sunday came, she was ready, but I had to ________ myself to leave the house to fetch the food package. On my way to the school, I fought an urge to ________. The Sunday paper and coffee were waiting for me at home. Why do this? ________, we phoned the elderly person we'd been appointed. She ________ us right over.

The building was in a bad state. Facing us was a silver-haired woman in an old dress. She took the package and asked us to come in. Nora ran inside. I unwillingly followed. ________ inside, I saw that the department belonged to someone poor. Our hostess showed us some photos. Nora played and when it came time to say goodbye, we three hugged, I walked home in tears.

Professionals call such a(n) ________ “a volunteer opportunity”. They are opportunities, I've come to see. Where else but as volunteers do you have the opportunity to do something ________ that’s good for others as well as for yourself? Nora and I regularly serve to needy people and ________ clothes for the homeless. Yet, as I’ve ________ her grow over these past four years, I still wonder-which of us has ________ more?

2 . To move visual technology into the future, sometimes it helps to make a little noise. Researchers have used sound waves to produce floating 3-D images, create a sense of touch and even supply a soundtrack.

Since the 1940s, scientists have toyed with the concept of acoustic levitation(声悬浮), the use of soundwave vibrations to trap tiny things in midair. The technology has gained greater capabilities in the past decade. Some researchers believe this improvement could lead to applications such as contributing to novel 3-D printing methods, or creating displays that would be visible from any angle without requiring a screen.

Other researchers have also worked on visual displays that use acoustic levitation. In addition to visuals, the system can also produce audible noise to give the display a soundtrack. And the ultrasound speakers can also concentrate vibrations in one spot so that a finger might feel a sense pushing back—a little like the object shown by the floating image is really there. Soundwaves create a 3-D display!

Display without a screen is remarkably useful. It means that everybody in the room can see the image—any angle, location—and that’s extremely helpful. As a communications system, such a display might one day allow users to chat with a 3-D projection(投影) of a person who can turn his or her head to follow as they move around a room.

The display will require a lot more work before you can install it in your living room, however. So far, this has been done in the research laboratory. We need to push it a little bit harder. We need to do more analysis to see if it would make sense to create a real display that people would have at home. The current system can only show simple graphics, such as a smiley face or figure eight, in real time.

Still, we are optimistic about the potential for this type of technology. If the system had only one speaker-covered surface instead of two, it could generate images that are bigger than the device itself. We can’t make a TV image that’s bigger than the TV—even a projector has to have a projection screen that’s bigger than the image itself. But with a volumetric(容积的) display, a small, portable device might produce a much larger picture. We can imagine, in the future, having volumetric displays in watches, for example, that create large images that just project out of your watch.

3 . Examples of effective conservation of places matter to the world. They range from the 1960s Nubian campaign to safeguard Ancient Egyptian monuments from the waters of the Aswan Dam to the removal in 2018 of the Belize Barrier Reef from the List of World Heritage in Danger. Conservation is the core purpose of the World Heritage Convention and it may also be its biggest challenge.

The following example shows how successes at specific sites now serve as models for conservation and sustainable (可持续性) development. A year after Vienna was included on the World Heritage List in 2001, the World Heritage Committee (WHC) expressed concerns about the architectural solutions and height of four planned towers of the Wien-Mitte project. This development project, close to the Historic Centre of Vienna in the site’s buffer zone, the one that lies between two or more other areas, affected the urban scale (规模) and visual effects in and around the property (地产). As a result of the Committee’s concerns, Vienna changed its building codes and launched a new design competition for the Wien-Mitte project to work out architectural plans with reduced size in keeping with World Heritage protection.

The successful practice inspired the government of the city to invite over 600 experts and professionals from 55 countries to an international conference on World Heritage and contemporary architecture, held in Vienna in May 2005. The global discussion that followed, detailing an approach to managing conservation and development, was recorded in the UNESCO Recommendation in 2011.

The Recommendation put forwards an all-rounded and combined approach to balancing urban heritage (遗产) conservation and economic development, arguing that active protection and management of urban heritage supports the goal of sustainable development.

The Recommendation supports the harmonious combination of contemporary involvement into the historic urban framework while holding on to values linked to history, memory and the environment.

A．To explain the goal of the organization.

B．To encourage the public to protect the world.

C．To show the positive effect of conservation.

D．To remind people of the environmental problems.

2. Why was WHC worried about the Wien-Mitte project?

A．It took up too much public land of the city.

B．It had a bad effect on the Historic Centre of Vienna.

C．Its original designs were not environmentally friendly.

D．Its architectural solutions couldn’t meet safety standards.

3. What did the global discussion focus on?

A．The ways to combine conservation and development.

B．The creation of the new UNESCO Recommendation.

C．The international urban management and development.

D．The styles of the contemporary architecture of Vienna.

4. What is the authors purpose in writing the text?

A．To examine the challenges faced by global urban planners.

B．To introduce alternative ways of protecting the environment.

C．To stress the importance of the value of history and memory.

D．To promote active conservation and sustainable development.
