The important things to consider when planning a multi-generational holiday trip

Take the whole family to a beach or a mountain, forming holiday memories that will last a lifetime. Whether those memories are pleasant or not will depend on a lot of things, but the one you can control most is how well you plan the trip. Multi-generational travel is different from planning for just yourself or your family. 1.

Perhaps your family is happy to have one person take control. But you may have newer family members who consider vacation planning a more collective experience. If that’s the case, you need to make sure they feel like they had some input in the process, or you won’t get much participation. 2.

Holiday resorts are likely a better choice than a big house or hotels, both because they offer separate condos (公寓式旅馆) where people can operate on their own schedules and because they offer activities, meals, and other entertainment (消遣) you won’t have to plan. Condos also often come with kitchens, if you do feel like having dinner at home a couple of times. 3. You might not want to share a hotel room with your brother and his wife, for example. But sharing a two-bedroom condo--which is usually about the same price — just feels like being roommates.

So finding a resort with activities that fit as many people’s interests as possible is key. 4. Your cousins may prefer doing food tours. Your father-in-law may just want a big pool. Regardless of what your family enjoys, think about everyone’s interest—or at least what you know of them—and find a place that has as many as possible.

5. Even if you’re leading the trip planning, leave group-activity planning to the people who want to do it as they’ll have the most drive and motivation (动机) to make it happen. Don’t force anyone into doing activities they aren’t interested in doing. So once you’re there, try your best to have a good time with them.

A.You may be a big diver.

B.Childcare on vacation is a big one.

C.The point of this whole thing is to have fun.

D.Making food for that many people is difficult.

E.And multi-bedroom setups allow for the less cost.

F.You’ve got all sorts of things to consider for a large group of people.

G.So making sure everyone’s planning styles are respected is an important early step.

    There’s nothing magical about the number 10,000. In fact, the idea of walking at least 10,000 steps a day for health goes back many years to a marketing campaign started in Japan for the sale of a pedometer (计步器). And, in the years that followed, it was accepted in the US as a goal to build up good health. It’s often the default setting (默认设置) on fitness trackers, but what’s it really based on?

“The original basis of the number was not scientifically determined,” says researcher I-Min Lee of Brigham and Women’s Hospital. She was curious to know how many steps you need to take a day to maintain good health and live a long life, so she and her workmates designed a study that included about 17,000 older women. Their average age was 72. The women all agreed to wear devices to track their steps as they went about their day-to-day activities.

It turns out that women who took about 4,000 steps per day got an increase in longevity (长寿), compared with women who took fewer steps. In fact, women who took 4,400 steps per day, on average, were about 40 percent less likely to die during the follow-up period of about four years compared with women who took 2,700 steps. The findings were published Wednesday in JAMA Internal Medicine.

Another surprise: The benefits of walking maxed out at about 7,500 steps. In other words, women who walked more than 7,500 steps per day saw no additional increase in longevity.

Janz, who released the new national exercise recommendations last November, says the message that comes from this study was encouraging. “I think it’s really good news for women who may not be particularly active.” says Janz. “All they have to do is walk. To me, this study suggests there are more benefits to light activities than we were previously thinking there might be.”

1.How did the idea of walking 10,000 steps a day come into being?

A.It was made up by a group of elderly ladies.

B.It was indeed the result of a scientific research.

C.It actually came from a business advertisement.

D.It was based on a test by both Japan and the US.

2.Which is an ideal choice for women walkers according to the study?

A.2,700 steps. B.4,400 steps.

C.10,000 steps. D.17,000 steps.

3.Which of the following does Janz agree with?

A.Light activities benefit people most.

B.The study is not as satisfying as expected.

C.Women should be more active than before.

D.The result of the study is a little surprising.

4.In which part of a newspaper can you read the passage?

A.Health. B.Culture.

C.History. D.Tourism.

    The Colorado River is the lifeblood of the American Southwest. It supplies water to more than 36 million people, has changed the desert into farmland, and allows cities like Los Angeles, Phoenix, and Las Vegas to develop. But satisfying the region’s need for water has come at a price.

The river once traveled all the way from Colorado’s Rocky Mountains to the Gulf of California. Now, dams (水坝) control the river’s water for human use. As a result, the river no longer reaches the ocean. Without water, the delta (三角洲) at the river’s mouth has become dry and poor.

To bring the delta back to life, engineers recently opened the Morelos Dam near the US-Mexico border to free a temporary burst of water. This pulse flow allowed the Colorad River to reach the sea for the first time in 16 years, helping the river’s delta come alive.

The dams built by the US government form a system of man-made lakes. These lakes can store four times the river’s yearly flow. “The lakes are like the river basin’s bank accounts,” says Taylor Hawes. “They provide a place to save up water for not-so-rainy days — like right now”.

In wetter times, on and off since the 1960s, the Colorado managed to complete its journey to the sea. During those rare times, spring floods temporarily brought life back to the delta. Seeing the difference a little water could make gave scientists the idea for this year’s pulse flow.

“Just add water and you get an amazing recovery,” says Eloise Kendy. “The project serves as a model of how to manage rivers sustainably (可持续) for both people and nature. A lot of rivers in the West have problems. We used them to make the deserts bloom and build cities. We didn’t think about the environment. But it’s possible to restore them. If we can do it in the Colorado River Delta, we can do it anywhere.”
