The day that you enjoy all{#blank#}1{#/blank#} satisfaction of having all the housework done by a robot might still be a few decades off. But increasingly engineers are saying that{#blank#}2{#/blank#} (robot) are going to make the leap from the factory floor to your family room.

    Bill Gates once predicted the “Dawn of the Age of Robots”. What's behind this new era? It's{#blank#}3{#/blank#} (part) a matter of technology. Devices that can recognize and respond to a human voice have been developed. There are now a few different ways for robots {#blank#}4{#/blank#} (move) around. They can walk crawl or ride on wheels. They are being made smaller and smaller these days and also {#blank#}5{#/blank#} (become) more and more efficient.

    A bigger part of the story depends{#blank#}6{#/blank#}the consumers. People around the world have tirelessly searched for ways to get{#blank#}7{#/blank#} (lazy) from the 1950s{#blank#}8{#/blank#} the television remote control was invented. Also {#blank#}9{#/blank#} (consider) the increasing wealth of people ，engineers believe the time appears ripe to introduce robots to ease our daily lives. Robots will do most of the basic housework {#blank#}10{#/blank#}just help you have more fun on the basketball court.

    Africa has been called the “dark continent” for a long time because {#blank#}1{#/blank#} lacks technology, electricity and other {#blank#}2{#/blank#} (achieve) of the modem world. However, it is beginning to change. Africa is starting to catch up with {#blank#}3{#/blank#} (industry) countries and the driving force behind this new development is the Internet and the World Wide Web.

    Now Africa is the fastest {#blank#}4{#/blank#} (grow) place on the earth. So far, governments, businesses and individuals {#blank#}5{#/blank#} (realize) that in order to develop quickly, modem technology is needed.

    Only ten years ago a SIM card used to cost about $100 in Niger. Today you can buy one for under $2 and phone calls have become much {#blank#}6{#/blank#} (cheap), too. As a result, 23% of its population are now mobile phone users.{#blank#}7{#/blank#} (equip) with this new service, people can connect to the Internet easily. Many Nigerians have access {#blank#}8{#/blank#} the World Wide Web now.

    In Ethiopia farmers can now get the prices of their farming products in real time. Until recently, most of the small farmers of the country did not know {#blank#}9{#/blank#} the prices of their products were at {#blank#}10{#/blank#} certain time. Today, they can phone in and get an up-to-the-minute report on prices.

    For thousands of years, fishes {#blank#}1{#/blank#} (feed) the people of Peru. It was only when the industrial fishing boats got started in {#blank#}2{#/blank#}1950s that people lost interest in the fish. Modern fishery turned most of its catch into fishmeal(鱼饲料) for feeding other animals. In fact, most of the fish {#blank#}3{#/blank#} (catch) yearly around the world are for use other than eating, and 90% of them are {#blank#}4{#/blank#} (perfect) good to eat.

    White is a researcher at the University of British Columbia and he spent years {#blank#}5{#/blank#} (research) into fishery catches around the world. According {#blank#}6{#/blank#} his study, about 27% of ocean fish which were caught became fishmeal or fish oil. Those products were used to feed farmed fish or used in agriculture.

    "There could be a {#blank#}7{#/blank#} (good) use of these fish," says White. Instead of feeding fish to fish, the fish could feed people, especially those {#blank#}8{#/blank#} need high-quality protein. But the reason why that doesn't happen is a {#blank#}9{#/blank#} (combine) of economics and regulations(法规). In many places, a fisherman can get more money if he sells his catch for fishmeal than if he sells it to the locals for {#blank#}10{#/blank#} meals. And in Peru, a change in how fishes are handled could both satisfy the need to feed the people and supply the fishmeal industry.

    China successfully landed the Chang'e 4 lunar probe(月球探测器)on the far side of the moon on January 3,2019, becoming the only country in history{#blank#}1{#/blank#}(touch) the lunar surface unseen by those on Earth. The far side of the moon has been seen and mapped{#blank#}2{#/blank#}(previous) by astronauts of the Apollo missions. But it is the first time that the moon's far side{#blank#}3{#/blank#}(set) foot on by any spacecraft, and the successful landing of Chang'e 4 is seen as a major milestone in space {#blank#}4{#/blank#}(explore).

    The Chang'e 4 spacecraft consists{#blank#}5{#/blank#}two parts:a lander and a rover(巡视器). Representing China's{#blank#}6{#/blank#}(new) step in the lunar probe project of all time, it landed at 10:26 am Beijing time. Then it sent back a photo of the landing place.{#blank#}7{#/blank#}(shoot) through cameras on the probe's lander, the photo marks the world's first image taken on the surface of the far side of the moon. One of the photos published by the China National Space Administration shows the place{#blank#}8{#/blank#}Chang'e 4's rover-named Yutu 2~will be heading hours later for{#blank#}9{#/blank#}purpose of conducting further research. The name Chang'e has its roots in the Chinese goddess of the moon. In the ancient tale, Chang'e{#blank#}10{#/blank#}(fly) to the heavens and landed on the moon as her final resting place.
