11．　　One Sunday, I decided to tidy my bookshelf up. Suddenly, a white envelope fell to the floor. I was (1)      ! I didn't put the envelope on my shelf. It must have been years ago!Anyway, I opened the envelope carefully. Inside it, there was a folded piece of paper. I read it. It was a letter written by my (2)      .
　　My dear children,
　　I love you so (3)      ! This is not a letter to be posted. I wrote this and hoped that one day you would find it. Yes, I wanted to let you know something that I thought was not suitable to express (4)      . That's why I wrote this letter to you all.
　　Life is too short and uncertain. What I say is not new at all, but why I say it is important. (5)       you are reading this, I am no longer with you. I'm not there to (6)       you or give you any kind of advice. But I believe that the steps (7)      take will be sound and wise.
　　The world around you can be confusing. But if you look inside yourselves, you can light your way and (8)      where to go. Remember the saying "you'll get what you sow (播种)." The way you act will have a great influence(9)       your life. Be careful and aware of every step. I hope you can understand what I mean. Be kind to others and to yourselves.
Yours love
Mom
　　I stood there for a long time, (10)       silently. I thought about how much I loved and missed my mother.

12．　　Do you know the two lovely mascots?You may know the five "Fuwa" dolls from the 2008 Beijing Olympic Games. On September 17, 2019, the two lovely mascots first showed on TV. Now, let's see who they are.
　　Look at the panda!It looks like an astronaut. It wears an ice shell and looks fat, so we call it "Bing Dwen Dwen". White is the colour of ice and snow. "Bing Dwen Dwen"likes ice sports very much and is good at them. That's why it is the mascot of 2022 Beijing Winter Olympic Games.
　　Do you think the red mascot looks like a lantern?The lantern's name is "Shuey Rhon Rhon". When the Chinese New Year comes, people always make or buy red lanterns. Red is the colour of hope and good luck, so people think their dreams will come true in the new year. "Shuey Rhon Rhon" can give players hope and help them do well in the 2022 Beijing Winter Paralympic(残奥会) Games.

13．　　There were many plants in a forest. When spring came, a pine tree saw a red rose nearby and said, "What a beautiful flower! I wish I were that lovely."
　　The rose proudly said, "It seems that I am the most beautiful flower in this forest." Then the rose looked at a cactus (仙人掌) and said, "Look at that ugly plant full of thorns!"
　　"What a proud flower!" thought the trees.
　　As the days passed, the red rose often looked at the cactus and said bad words about it, like "This plant is useless. How sorry I am to be his neighbor!"
　　The cactus never got angry and even tried to advise the rose, saying, "God did not create any form of life without a purpose."
　　Spring passed, and the weather became very hot. As there was no rain, the red rose began to wilt.
　　One day the rose saw birds put their beaks (喙) into the cactus and then fly away. The red rose asked the pine tree what the birds were doing. The pine tree explained that the birds were getting water from the cactus.
　　"The cactus has water?" asked the rose.
　　"Yes, you can also drink some from it. The birds can bring water to you if you ask the cactus for help."
　　The red rose felt too ashamed to ask for water from the cactus. But finally it did ask for help. The cactus kindly agreed.

14．　　Life comes in a package (包裹). This package includes happiness and sadness, failure and success, hope and despair. Life is a learning process (过程)! Experiences in life teach us new lessons and make us a better person. With each passing day we learn to deal with different situations.
　　Love plays a main role in our life. Love makes you feel wanted. Without love a person could become cruel.
　　In the early period of our life, our parents are the ones who show us with love and care. They teach us about what is right and wrong, good and bad. But we don't always care about it. It is only after our marrying and having kids that a person understands others' feelings.
　　Happiness can bring people a peaceful mind. No mind is happy without peace. Sadness is the cause of the death of a loved one or the failure. But all of these things will pass away.
　　Failure is the path to success. It helps us to touch the sky, teaches us to survive and shows us a specific way. Success brings in money, pride and self-respect.
　　Hope is what keeps life going. Parents always hope their children will do well. Hope makes us dream. Hope builds in patience. Life teaches us not to despair even in the darkest hour, because after every night there is a day.
　　Life teaches us not to regret over yesterday, for it has passed and is out of our control. Tomorrow is unknown, for it could either be bright or dark. So the only choice is to work hard today, so that we will enjoy a better tomorrow.

15．　　You can travel alone, with friends, or with a tour group. They all have strong points and weak points.
　　The best thing about traveling alone is that you can do what you want to do. No waiting around in places you aren't interested in, no missing a bus because your friend was late, etc. This may sound selfish, but this is your experience. Your experience will be greatly improved by traveling alone. The main worry is loneliness, but believe me, it's not difficult to talk to and meet people. Just remember everyone is in the same boat;everyone wants to meet new people, have fun and be friendly!There's a problem of safety in some countries, especially for women traveling alone. You should always check the foreign office of your country for advice on safety. Buying a personal alarm is a good idea for women traveling alone.
　　Traveling with a friend does sound nice, but it depends on how well you get on. If you have similar interests or travel ideas, it should be wonderful. You will find it much cheaper to cook food in developed countries and share a room. However, a lot of people I meet traveling together don't seem to be having as much fun and often go their separate (各自的) ways.
　　Tours are great when they go well. Some of my best memories have been with tour groups. The key there is when they go well. A terrible tour guide, quiet group and terrible food can ruin (毁掉) your time. My advice would be never to do a tour that is too long except in countries with safety problems or poor transport.
　　All in all, traveling alone is the best, but it is good to mix it up. Invite a friend from home to meet you for a few weeks. Try a tour or two﹣﹣some people love them﹣﹣perhaps start with a day tour.

16．　　Robot scientists say that one-year-old human babies have better movement (动作) skills than robots do. Let's take a look at some tasks that are easy for kids but not easy for them.
　　Picking things up is not easy for robots. If we drop our pencil on the floor, our brains work hard. First, we must find the pencil and see where it is. We move our hands to it. A robot cannot always move its "hand" to the right place. A robot doesn't know how far it is. When we touch the pencil, it might roll (滚动) a little bit. Robots cannot easily understand this, either. So, if you drop a pencil on the floor, a robot will probably roll it around the room.
　　If someone drops you in a new building, you might feel a little lost. But you can look around, find a door and get out quickly. You will not get stuck (困住的) in a corner. But a robot will look everywhere for a door, even on floors. This is because it's hard for them to understand spaces, such as walls. Scientists need to train them with lots of data to learn this.
　　"Common sense (常识)" is what we don't need to think or talk about. Because of it, we do not look for doors on the ceiling. We feel whether it has coffee inside, and whether it is hot. A robot may turn the cup upside down and hold the hot part of the cup. Scientists tried to teach robots common-sense rules. Maybe they just need more time to learn.
