Can you imagine a cloud floating in the middle of your room？ Do you want to know what it feels like to fly like a bird？ Find your answers in Time Magazine's 25 "Best Inventions". Here, we have picked out the most interesting 4 to share with you.
Talking Gloves
Ever felt confused by the sign language used by disabled people？ Here is the "helping hand"you need. Four Ukrainian students have created a pair of gloves that helps people with hearing and speech problems communicate with others. The gloves are equipped with sensors that recognize sign language and translate it into text on a smartphone. Then the smartphone changes the text to spoken words.

The glasses also have a camera and GPS mapping system. Users can take and share photos, check maps and surf the Internet just by looking up, down, left and right.
Indoor Clouds
It's not virtual.That's a real world.Dutch artist Smilde managed to create a small but perfect white cloud in the middle of a room using a fog machine.But it required careful planning-the temperature, humidity（湿度）and lighting all had to be just right.Once
everything was ready, the cloud formed in the air with the machine.But it only lasted for a short while.
Wingsuits
The suit fulfills your dreams of flying like a bird.Well, not exactly flying, but gliding（滑翔）through the air.It increases the surface area of the human body, which makes it easier for people to float in the air. Fliers wearing wingsuits can glide one kilometer in about 30 seconds.

Dale Carnegie（戴尔·卡耐基） was an American writer and lecturer,
and the developer of famous courses in self-improvement, salesmanship, corporate training, public speaking and interpersonal skills.
Born in 1888 in Maryville, Missouri, Carnegie was a poor farmer's boy.His family moved to Belton, Missouri when he was a small child.In his teens, though still having to get up at 4 am every day to milk his parents' cows, he managed to obtain an education at the State Teacher's College in Warrensburg.His first job after college was selling correspondence courses.He moved on to selling bacon, soap, and lard（猪油）for Armour&Company.
After saving $500, Dale Carnegie quit sales in 1911 in order to achieve a lifelong dream of becoming a lecturer.He ended up instead attending the American Academy of Dramatic Arts in New York, but found little success as an https://www.doczj.com/doc/b71631523.html,ter he got the idea to teach public speaking.In his first session, he suggested that students speak about"something that made them angry", and discovered the technique that made speakers unafraid to address a public audience.From its beginning, the Dale Carnegie Course developed.Carnegie had made use of the average American's desire to have more self-confidence.
Perhaps one of Carnegie's most successful marketing moves was to change the spelling of his last name from"Carnagey"to Carnegie, at a time when Andrew Carnegie was a widely recognized name.

Developing healthy eating habits starts from childhood, therefore it is important for parents to teach and provide children with a healthy diet. DPHSS administrator of the Bureau of Nutrition Services, Charlie Morris told KUAM News, “A healthy diet for a child consists of a lot of fruits and vegetables in the diet limiting the amount of simple sugars in the diet and high fat food and highly processed（加工的） food.”
This means staying away as much as possible from food such as chips, cookies, candies and sugary drinks, as all children need to have meals which involve a well-balanced diet. Community nutritionist（营养学家） Thelma Romoso said, “The fruit, the vegetable, the grain,
the protein, and also the milk, the diary product, so for the fruits it's easy for a mother to go into the two plus three concept of fruits and vegetables or five a day.”
This concept means that there are at least two servings of fruits a day, three servings of vegetables a day which can be served for lunch and dinner. As for protein parents can make a variety of dishes from chicken, beef, fish or even dried beans to make sure the child gets three servings a day.
Morris said that the child's hunger level controls how much is eaten and the parent controls what and when the meal is offered, saying, “Mom needs to ensure that the food offered is good food for the child to eat and throughout the day depending on how active they are, snacks（零食） are not a bad thing, so the mom should offer good kinds of snacks.”
When it comes to preparing your child's lunch and snacks for school, make sure to keep in mind that the food you provide should not only be a source of energy but also be nutritionally beneficial such as fresh fruits, and whole grain bread. But parents must be sure to remember that a good nutritional diet must be balanced with physical activity, namely it is important that children get outside and run around and play and get activity in addition to eating a good diet.
32.What does the author intend to tell us in the text？
A.Fruits and vegetables are good for your child.
B.Choose healthy food and snacks for your child.
C. Take steps to provide a good lunch for your child.
D. Make various and delicious dishes for your child.
33. According to Charlie Morris we can know that_________.
A. highly processed food should be reduced in daily life
B. mothers should prepare delicious food by themselves
C. sugars and high fat exist in few kinds of food
D. active children prefer more and more snacks
34. Which is NOT true when preparing your child’s food for school？
A. The food must provide energy as well as nutrition.
B. Running and playing when eating is beneficial.
C. Physical exercise is as important as a good diet
D. Fruits and whole grain foods should be included.
35. It can be inferred from the text that _________.
A. Fresh fruits are often ignored by children
B. A good nutritional diet may cost too much
C. Parents play an important role in children's diet
D. Choosing healthy food is linked with income

Dear Editor,
I am Li Hua, a student of Senior One. I have some trouble in learning English and hope you can give me some useful advice.
There is always a long list of new words in my book. I have never learned them before. It is a hard job for me to remember the spelling of them and even the Chinese meanings. So I cannot understand what the English teacher says in class. I become worried and afraid that I will fall behind in English. Could you please give me some advice on how to learn English？ I am looking forward to your early reply.
Best wishes！
Yours sincerely， Li Hua

河南省周口市中英文学校2020-2021学年高三上学期第一次 月考英语试题 学校:___________姓名：___________班级：___________考号：___________ 一、阅读选择 It's 10:30 pm, and 11-year-old Brandon Blanco is sound asleep at home. Suddenly, a loud noise wakes him up. Naturally, Brandon reaches for his cell phone. The message becomes clear: "R U awake?" Brandon' s use of technology doesn' t stop there. He also has a computer, a TV and three video-game consoles (控制台) in his room. With so many choices, it' s no surprise that when he isn' t at school, he spends nearly every waking minute using one or more of these devices. Brandon is hardly alone. According to a recent study by the Kaiser Family Foundation, kids aged 8 to18 are spending more time than ever before using electronic devices. How much time? More than seven and a half hours a day on average, the study found. The jump is the result of a huge explosion in mobile devices, says Victoria Rideout, the lead author of the study. Today, nearly seven out of ten kids have cell phones. Just five years ago, it was four out of ten. Often, kids multitask, or use more than one device at a time. " If you’ve got a chance to do something on your computer and take a phone call and have the TV on in the background, why not?" media expert Cheryl Olson says. Most experts agree technology has much to offer kids. But some worry the kids could be missing out on other activities like playing outside or hanging out with friends. " It' s a matter of balance," says Olson." You’ve got to work on it. " Multitasking while doing homework is another concern. Some kids listen to music, watch TV or use the phone while doing their homework. "It' s important to make sure that you can stop and concentrate on one thing deeply, " says Rideout.
