Philo Farnsworth was a man who made it possible for one of the most important communication devices-television to be created. Philo was born on August 19th, 1906, near Indian Creek in the western state of Utah. He attended a very small school near his family's farm. He did very well at school. He asked his teacher for special help in science. The teacher began helping Philo learn a great deal more than most young students could understand.
One night, Philo read a magazine story about the idea of sending pictures and sound through the air. Anyone with a device that could receive this electronic information could watch the pictures and hear the sound. The magazine story said some of the world's best scientists were using special machines to try to make a kind of device to send pictures.
14-year-old Philo decided these famous scientists were wrong and that mechanical devices would never work. He decided that such a device would have to be electronic. Philo knew electrons could be made to move extremely fast. All he would have to do was to find a way to make electrons do the work.
Very quickly Philo had an idea for such a tube. It would trap light in a container and send the light on a line of electrons. Philo called it “light in a bottle".
Several days later, Philo told his teacher about a device that could capture pictures. He drew a plan for it, which he gave his teacher. Philo's drawing seemed very simple, but it clearly showed the information needed to build a television. In fact, all television equipment today still uses Philo's early idea.
Philo Farnsworth was only 14 years old then. He knew no one would listen to a child. In fact, experts say that probably only ten scientists in the world at that time could have understood his idea.
On September 7th, 1927, Philo turned on a device that was the first working television receiver. In another room was the first television camera. Philo had invented the special camera tube earlier that year.
The image produced on the receiver was not very clear, but the device worked. In 1930, the United States government gave Philo patent documents. These would protect his invention from being copied by others.

Inventions make the world better, smarter and even a little bit more fun. Last year, in November, Time magazine published "2018 Top 50 inventions". Here are three of the most interesting inventions for you. Let's take a look.
Lifepack Carry-on Closet
In many cases, traveling is fun, but packing can be quite annoying. No matter how neatly you pack your clothes, you always end up having to pull out everything in order to find what you need. Well, the Lifepack Carry-on Closet designed by the Danish startup Solgaard Design might change that for good.
From the outside, the Lifepack looks like an ordinary suitcase. But inside, it contains a set of retractable shelves to keep clothes in good order and maximize the space. Its shelf system has many extra pockets and is removable. So when you get to your destination, you just need to take out the shelf system and hang it in your hotel closet.
LynQ
Becoming separated from friends in crowds or losing contact with your family in a strange place can be a nightmare.
But now, LynQ, a new location tracker, has a fix.
When you wear LynQ, you use a combination of GPS technology and long-range radio frequencies to find other LynQs to a distance of up to 5 kilometers from you. In addition, an onscreen dot points each user in the right direction, like a compass.
As Time notes, "LynQ solves the three Ws: No more worrying, wandering or waiting around. "
Gravity jet suit
If you're a big fan of Iron Man, you must have been impressed by his amazing jet suit. Now, there is a real gravity jet suit for us to try.
Developed by London-based technology company Gravity Industries, the flying suit is equipped with five power engines—four are built into units close to the hands and one is built into a backpack.
If these engines fuel together, they can provide 1,050 horsepower to make the wearer move at a speed of up to 51 kilometers per hour. So, for people who can balance with the suit on, it's easy to fly.
1.From the description of LynQ, we can learn that_________.
A.it is a traditional advanced GPS system B.it is a wearable device
C.it is based on a compass D.it makes its users worry-free
2.Which of the following statements is TRUE?
A.It's easy for people to fly because Gravity jet suit can provide adequate power.
B.You won't worry about losing touch with your family once you wear LynQ.
C.Lifepack Carry-on Closet can make packing easier with unique design.
D.Traveling will become more convenient and cozier with the three inventions.
3.What's the purpose of the passage?
A.To introduce some interesting inventions. B.To comment on the latest technology.
C.To appeal to more consumers. D.To promote some creative products.
