On Earth, sunlight can be covered by clouds and there is no sunlight at night. But in space, the sun shines all the time.

Imagine being able to use energy from the sun all the time. Scientists at Caltech (California Institute of Technology) are working on collecting sunlight in space and sending its energy to Earth. They have created a special tool called MAPLE for this project. MAPLE’s job is to test the idea of sending energy wirelessly(无线地) from space to Earth. It is a lot more difficult because we usually use wires to move electrical energy from one place to another.

To show that MAPLE could work, the scientists did a test. MAPLE sent energy to two devices (设备) 30 cm away in space. The energy was then turned into electricity, MAPLE sent energy to a lab at Caltech. The scientists were able to discover the energy, showing that it’s possible to send energy from the sun to Earth from space.

The scientists at Caltech are now trying to find ways to improve MAPLE. In the future, they hope to launch (发射) many large devices. Each will have huge solar panels (太阳能电池板), along with MAPLE devices to send the energy down to Earth wirelessly.

Using MAPLE, the scientists will be able to send the power to exactly where they want it, either in space or on Earth. Dr. Hajimiri, thinks that one day MAPLE could bring energy to places that need it, helping more people all over the world.

【小题1】What does the underlined word “It “refer to?
A.Being able to use energy.
B.Collecting sunlight in space.
C.Sending energy to Earth from space.
D.Moving electrical energy to another place.
【小题2】What does Paragraph 3 mainly talk about?
A.How the scientists tested MAPLE.
B.What problems the scientists faced.
C.What the scientists discovered in space.
D.How the scientists sent MAPLE to space.
【小题3】What do the scientists hope to do in the future?
A.Add more panels to MAPLE.
B.Send more large devices into space.
C.Do more scientific tests in the lab at Caltech.
D.Turn more energy from MAPLE into electricity.
【小题4】What does Dr. Hajimiri think of MAPLE?
A.It will be widely used soon.
B.It will take time to get popular.
C.It will be very useful to humans.
D.It will be hard for people to accept it.

As the world of technology is developing very fast, it brings out exciting new inventions which are building a better future. From e-books to robots, the newest inventions are pushing the boundaries (边界) of what we thought was possible. In this article, there are some of these amazing new inventions. Let’s find out the latest and greatest inventions that are shaping our future.

Smart Schoolbag

Forget to pack the books you need into your schoolbag in the morning huh?

A schoolboy aged 11 has invented a schoolbag. It tells you which books to pack. A small computer and a scanner (扫描装置) are fixed in the bag. As each book is put into the bag, it is checked by the scanner. If any book is missing, a message will be shown on the computer screen to remind you.

Weather Sweets

Can you eat weather?

A university makes that happen. It uses a 3D printer to create sweets based on the weather information of a certain day.

The shapes of the sweets are affected (影响) by wind speed. The colors of the sweets are decided by temperature. The sweets act as a weather record of the day when they are made.

Sunrise Bed

It’s hard for you to get up in the morning, isn’t it?

To help you get up, a company has created a kind of “future”—a sunrise bed. It wakes you up gently as a sunrise does. Lights built into the bed turn on and start to get brighter and brighter. When the lights are fully on, soft music will begin to play. It will be louder and louder until you turn it off. The company explains, “The gentle light tells your body that it is morning, so it stops producing a chemical that helps you sleep.”

It’s exciting to think about all the amazing new inventions that are changing our world. These new technologies are making life easier, more fun and more connected and they make the future look bright.

Print a mobile phone at home. Download a film in just one second. Amazing things like these might become reality in 2019 as new technology enters our lives. Check out a few examples here.

Iron Man Suit

Have you ever imagined what fun it would be to fly to school? This Iron Man-style suit from a British company could make your dreams come true. The suit allows users to fly just like Iron Man. It can reach a top speed of 80 km per hour. There is a long way to go before this technology is available to everyone, as the suit is still quite expensive — one model is sold for $440, 000 (about 3 million yuan). It is also very noisy.

3D-printed houses

There are 1.2 billion people in the world who don't have a proper house to live in. The 3D-printed houses made by ICON in Texas may help to solve this problem. The company can print a single-storey house of 60m2 in just 12 to 24 hours. The walls of the house are made of a special cement (水泥) that looks like cream. The 3D-printed houses use less cement than normal houses. 100 homes will be built for people in the Republic of Panama this year. Each house costs only $10,000.

Huawei Mate X

Is it possible to fold your phone screen? Huawei's newest phone, the Mate X, is foldable. You can fold it in half as if you are closing a book. The Mate X is very thin, working as both a phone and a tablet (平板电脑). When folded, it works as a phone. When unfolded, it is a tablet. The other highlight of Mate X is that it supports 5G which means users can download a whole movie in just a second. But users can take selfies only when the phone is folded, because the phone doesn't have a front camera.
