Is it necessary to learn when we are 50s, 60s or even 70s?Most people consider when they get retired, they are supposed to be completely laidback, do something fun, or hang around.1. It’s particularly important to the elderly.
Through learning, we know how to think, how to memorize, how to ask questions and even how to interact with others. According to a study, while we are learning, “the brain creates neural(神经)pathways” that make us smarter. 2. The more we learn, the mote new neural pathways develop in our brains.
When it comes to learning, it doesn’t mean we must load ourselves with lots of knowledge. What we need to do is just learn something we like day in and day out. 3. Everyone learns from bottom to up. If we have an interest to learn, that desire will naturally push us to move forward.
As we feel worn out from learning, don’t be discouraged.4. An old saying goes, “Birds of a feather fly together.” As long as we have partners to learn all together, our learning excitement will come alive again. On the contrary, if we don’t learn, and choose to distance ourselves from other, we might be getting dumb, and slow; eventually, we lose energy, and life passion. Instead of being bored, dumb, why don’t we keep learning?
5. More importantly, learning explores our life horizon, helps us build up our confidence; gradually, it leads us to a way of finding a sense of value and ach.
A.It’s never too old to learn.
B.Don’t worry if we cannot learn well.
C.You should set a high learning target.
D.Learning makes us understand how potential we are.
E.Look for a partner who has the same common interest as you do.
F.In other words, our brains are active as we learn something new.
G.However, the truth is that learning makes us energetic, and self-fulfilled.

The summer is so hot and sticky, why would we want to sweat even more by exercising? Or is it just I who think like that? Sweat and clothes sticking to our bodies as we move make exercise seem rather uncomfortable. What can be done to fix it?
Researchers at MIT have come up with a solution. They’ve developed a workout suit with flaps that open as the wearer begins sweating. As the person cools off, the flaps shrink until they assume their original position.
Sounds cool, sounds practical. These flaps are lined with live, microbial ( 微生物的)cells. These cells can detect when the body is heating up too much, and in response, expand. It’s just as if they were working within any other organism, recognizing patterns of heating and cooling, then responding appropriately to maintain body temperature. It seems kind of strange to have living cells (that aren’t your own) on you, right? Not to fear, these cells have been believed safe. Plus, there’s a material in the suit that helps the flaps/cells hover ever so slightly above the exerciser's skin. The flaps start opening as soon as people start feeling warm and sweaty, and the bit of space between the suit and the skin helps develop that feeling of cool and refreshing air as they move. For more information about flaps, click here.
According to Gadgetify.com, researchers have also been working to apply this technology to running shoes as well. Moisture-responsive workout clothing has the potential to revolutionize sport fashion industry. People can stay drier, cooler and fresher at the end of the workout, which sounds better than leaving the gym with a trail of sweat and a red face. It’s possible that the comfort of these suits can make people enjoy exercising more and exercise with more intensity.

We all know the dangers of fires. It’s good and necessary for a family to learn how to prepare for a fire. Here are some suggestions.
Put a smoke alarm(火警) in the house. Smoke from a fire causes the alarm to go off. The alarm makes a loud sound. The sound tells everyone to leave the house at once.
Make escape plans. We should know all the ways out of the house. If there is a fire, everyone follows the plan to get out. Part of the plan is to check all the windows to make sure they can be opened easily.
Buy fire extinguishers(灭火器) in the house. Everyone in the family should know how to use them.
Practise for a fire. We do fire practice because we teach children about fire safety. Everyone in the family should know the following fire rules:
★Don’t open a hot door! The fire can grow more quickly if you open the door.
★Stay close to the floor! Smoke can be more dangerous than fire. The best air is near the floor because smoke rises.
★What will you do if your hair or clothes start to burn? First, stop! Don’t run! The fire burns faster because of more air. Drop! Fall to the floor. Then roll! Turning over and over will make the fire go out. Put a blanket(毯子) around you to keep air away from the fire that may still be on you.
There are many possible causes for fires. A wise family is ready all the time. If there is a fire, don’t forget to call 119 for help.

Dear Mr Green,
I am very exciting to learn that we are going to start a magazine together. It is indeed a wonderful idea and everyone hopes its success.
I would like a magazine to have three columns: News, Teachers’ Advice or Students’ Voice. From the News column we can learn about what was going on in both of our schools. In Teachers’ Advice, our teacher can give us such help that we may not be able to get in the classroom. Students’ Voice will allow us to free express our thoughts and feelings about our lives and studies.
I believe that this magazine will surely strengthen between our ties, and I am looking forward to read it.
Yours faithfully,
Li Hua

When it comes to making sure our food is safe, we are often advised to wash vegetables and fruits before eating. This has been a good method recommended by food safety experts. However, is this way of cleaning also useful for raw meat? No! The US Departement of Agriculture hs been warning people against washing raw meat before cooking , as it can do more harm than good to our health. Then, why do people want to wash raw meat? Here are some answers.
Some people complain that the unpleasant smell coming from the chicken forces them to wash it.Well, this might never happen if you have bought it from a reliable source. Also, many people say that it helps to get rid of the sliminess(粘连) of the store-bought chicken. And others just want to remove the bacteria from it. But the idea that washing meat helps to clean the chicken is only partly true. This is because some of the bacteria remain firm on the surface, though the meat has been washed several times.
In fact, the surface of the chicken is often polluted with a lot of bacteria. So, when you wash the meat under the tap, it can lead to the bacteria being removed from the meat’s surface, and spreading all over the kitchen. These small infected(受到污染的)water drops can move as far as half a meter. So if you have kept any ready-to-serve dishes on your kitchen top, they are likely to get polluted, and may cause food poisoning if they are eaten.
Of course, if you are really serious about food safety, make sure that the chicken is cooked in a proper way. Eating undercooked meat is another common cause of food poisoning. Bacteria can be killed by the heat of above 70℃. This is the best way to get the bacteria present on raw meat destroyed.
In conclusion, food safety is important but that doesn’t mean that you have to wash raw meat with running water, which carries a lot of health risks.
Should raw meat be washed before cooking? | |
Topic | The Us Department of Agriculture has given a(n) 1._________ that it’s unnecessary to wash raw meat before cooking. |
2.____for people’s washing raw meat | Some people wash raw meat to get rid of its bad 3._____. Some people wash raw meat to get rid of its sliminess. Some people wash raw meat to get rid of its bacteria, but it’s 4._____ to wash all of them away. |
