Next week, strangers with a truck will take away everything we own, except the clothes on our backs, the car we will drive, and as much stuff as we can pack into it. It's called moving. Some people do it often. For others, like me, it's a rare experience. In all my adult years, I've moved only three times.
My first husband and I moved into our first house with a bed, our clothes and a few gifts. That was a lifetime ago. Over the years, I filled that house with three children, a few dogs and enough stuff to reach the ceiling.
When the kids grew up, I lost my husband to cancer, and I began to learn about letting go. First, I let go of the idea of being in control. Life isn’t about being in charge of what happens; it's about being in charge of what we do with it. Next, I let go of putting off the things I care most about, like keeping in touch with the people that mean the most to me. I let go of the people whose lives are about anger or hatred, and tried instead to surround myself with those who shine with kindness. Finally, I let go of being alone---I remarried. I eventually moved to a new city with my new husband, and after that move, I promised I'd stop collecting meaningless things. But 12 years later, here I am, still learning about letting go.
Yesterday, while cleaning out a dresser, I found a box filled with old keepsakes. Nothing in that box may mean much to anyone, except me. They are treasures for me because of the memories they preserve. We finally decided to keep them, hold them close and never let them go. We’ll all move someday from this world to the next, but we won't need a truck to do it. We'll take nothing with us and leave behind a memory of the life we lived, the mistakes we made, and all the love and kindness we tried to show. That memory might not be a treasure, but if we're lucky, someone will keep it and hold it close and never let it go.
1.According to paragraph 3, which of the following might the author advise?
A.Never let all the memories go as they are.
B.Put off the things that mean the most to you.
C.Wherever you go, you should be kind to others.
D.Life is 10% what happens to you and 90% how you deal with it.
2.The underlined word ''keepsakes'' in paragraph 4 is closest in meaning to_________.
A.something memorable B.something expensive
C.something unpleasant D.something beautiful
3.What is the author's main purpose in writing the article?
A.To stress the importance of letting the past go.
B.To give advice on how to make choices before moving.
C.To share how she learned to make important choices in life.
D.To explain how our memories can pass on to later generations.
Of all my dreams, my least favorite is the one where I'm in a car. It always begins with me driving, but eventually I realize that for some reason I'm sitting in the back seat. I can’t keep the car under control, rushing toward the roadside until, screaming, I wake up.
This is like the passenger experience in Waymo's self-driving cars. You sit in the back seat of a vehicle and watch as the wheel turns itself above an entirely empty driving seat.
''We made you live your nightmare, '' a Waymo staff member joked after I exited one of the company's fully self-driving car, following a quick drive inside its secret testing site. Waymo, a self-driving car company, arranged these rides for 40 journalists at this site.
There were also some demonstrations(演示). We watched as a Waymo car was cut off by a speeding vehicle. Then the employees created a situation in which a pile of moving boxes fell into the street just as another car passed in the opposite direction. Throughout the day, the cars performed impressively, driving with the level of care you might take if you had a wedding cake in the back seat.
During these demonstrations, Waymo gave information about what it was planning to do with these vehicles. The company has laid out four ways that its technology could be made available to the public. But Waymo's CEO, John Krafcik, wouldn’t show which of these was likely to come to market first, or on what kind of timeline.
I can't help but admire that Waymo is succeeding in developing this technology. There are countless possibilities at play on the road. The task of programming software to react to all those situations is unimaginably complex. What a great breakthrough!

According to a recent report, about 15% of the people in the UK are members of gyms. But are they more likely to be fit?
A study found that gym members were 14 times more active than people who didn’t belong to any health club. Gym members did six hours more exercise a week, and this activity did make them fitter than non-gym members. They also spent less time sitting down every day than non-gym members. The results were the same for men and women.
The study included 405 people between the ages of 30 and 64, and the main characteristics of those who were gym members were the same as those who were not. ''But gym members did more training than non-gym members, '' said the lead author, Elizabeth Schroeder of the University of Illinois.
While it might seem clear that gym members exercising more are healthier than non-members, Schroeder says this has not been directly shown before. However, the study is only designed to show a tie between gym membership and more exercise. It may be that active people like to join gyms. In the study, people who exercised as much as gym members were also in good health.
You can get the same benefits wherever you exercise. This study shows a gym membership can make you do more exercise, but other research shows that exercising outside has other help. Outdoor activities can make you feel happy about life—especially if you run through a forest.
Outdoor exercise is also more enjoyable than going to the gym. The first five minutes of outdoor exercise is especially helpful in making people feel good. But Schroeder says that a gym may also encourage greater exercise because it can be social and fun.
1.What did the new study find out?
A.Gym members had healthier eating habits.
B.There were fewer women gym members than men.
C.Gym members did at least eight hours of exercise a week.
D.Gym members were more active than non-gym members.
2.In the study, researchers studied ____________________.
A.some sports lovers
B.405 gym members
C.people from different age groups
D.30 gym members and 64 non-gym members
3.Which of the following will Elizabeth Schroeder agree with?
A.Women should do more gym exercise.
B.We should be careful with outdoor training.
C.Outdoor exercise is better than gym exercise.
D.It is easier to keep exercising if you go to the gym.
