Blade and future are words of open syllable.

Many discussions take a【C1】______view that the workforce will indeed be【C2】______by robots in the future—and why that is a good thing. Carl Bass, the chief executive of Autodesk, acknowledged that workplace automation has【C3】______or reduced many manufacturing jobs, and will continue to do so in the future,【C4】______major shifts in the labor market. Entire【C5】______such as trucking, will eventually be disrupted by robotic【C6】______like self-driving cars, he said. But, Bass asked: "Are the jobs【C7】______to automation ones that you would want for your children？" Few parents, he said, dreamed their kids would someday become fuel pumpers or elevator【C8】______jobs already replaced by automation. In the next 30 years, Bass added, smart machines and robots will【C9】______humans on the planet. Bass presented some【C10】______ideas to help societies deal with the structural【C11】______generated by a robot-heavy workforce, including taxing economic output rather than income, or【C12】______a "negative income tax," in which governments pay citizens a subsidy in order to【C13】______a level of income. "With our【C14】______and imagination, we will find harmony with the robots," Bass said. 【C15】______, other discussions focused on identifying jobs which were likely to remain【C16】______from robots. For example, hairdressers might be considered safe. But not because robots cant cut hair—the relationship between hairdressers and their【C17】______simply cant be robotized(And, some people might be【C18】______of a robot holding a sharp blade so close to their necks,【C19】______plenty of robots already perform. delicate surgery.) Another job【C20】______safe？ Roboticist.

th. But it is【C1】______ oneself that one has the【C2】______ understanding of.

When you are going upwards in life you tend to【C3】______ yourself. It seems that everything you seek for is within your【C4】______ ; luck and opportunities will come your【C5】______ and you are overjoyed that they constitute part of your worth. When you are going downhill you tend to underestimate yourself, mistaking difficulties and【C6】______ for your own【C7】______ . It's likely that you think it wise for yourself to know your place and stay aloof【C8】______ worldly wearing a mask of cowardice, behind which the flow of sap in your life will be【C9】______ .

To get a thorough understanding of oneself is to gain a correct view of oneself and be a sober 【C10】______ -- aware of both one's strength and shortage. You may look【C11】______ hopefully to the future but be sure not to expect too much, for ideals can【C12】______ be fully realized. You may be【C13】______ to meet challenges but it should be clear to you【C14】______ to direct your efforts. That's to say so long【C15】______ you have a perfect knowledge of yourself there won't be difficulties you can't【C16】______ , nor obstacles you can't surmount.

To get a thorough understanding of oneself needs【C17】______ . Whether you like yourself to a towering tree or a blade of grass, whether you think you are a high mountain or a small stone, you【C18】______ a state of nature that has its own value of existence. If you earnestly【C19】______ yourself you'll have a real sense of self-appreciation, which will give you confidence. As soon as you gain full confidence in yourself you'll be【C20】______ to fight and overcome any adversity.

To get a thorough understanding of oneself is to get a full control of one's life. Then one will find one's life full of color and flavor.

est drug on the market that they use; it's also the most up to date equipment. Innovations include: the use of the contemporary bicycle against the recumbent(斜卧式)bicycle, the texture of a golf ball to take full advantage of its traveling distance, the traditional wooden bat versus the new aluminum bat which is said to maximize one's athletic talent. Hockey has had changes. Perhaps one of the biggest changes of all was the mandate to wear a helmet. Today, the size and shape of pads, goalie equipment and even their sticks have been changed from wood to graphite(石墨). All of these efforts are in an attempt to "improve" the performance of athletes. Even figure skating(花样滑冰)is using technology to advance its skaters. There isn't just one brand of skate that skaters use. There are numerous different boots that all apply to what category of skating they do. For instance, a dancer and a single's skater would not have the same skate. Each boot and blade would be fit in order to maximize his or her performance. A single's skater's boot would be incredibly padded, sturdy and strong in order for them to land those powerful jumps. Yes, it is a safety issue as well, but this technology has led skating to the level it is at today.

All in all, it is quite hard to say whether we should be accepting these new technological advances or whether we should be sticking to the traditional model of sport. We are currently in the middle of both drug use and the use of new and innovative equipment as far as I can tell. Where are we going to progress from here？ Are athletes actually going to put microchips in their brain in order to attain an athletic title？ The future holds many options for the outlook of sport, and it will be interesting to address tradition in sport in the years to come.
