You might dream of fluency in this or that language, and maybe you've already achieved fluency in a foreign language.{#blank#}1{#/blank#}.

    Fluency, like all abstract terms, has no universal meaning. Each individual must determine what the term means.{#blank#}2{#/blank#}.

    Perfect fluency means knowing every word you encounter, speaking quickly, clearly and easily and having no accent.{#blank#}3{#/blank#}. You aren't familiar with every word of your native language, and sometimes you have to search for the right word, even in your mother tongue.

    Quick fluency is the type of fluency you see in advertisements, because “Master a Language in Two Months!” sounds way catchier than “Fluency in Twenty Years!”{#blank#}4{#/blank#}. It is possible to achieve quick fluency, but the fluency achieved after such a short time frame will be a very thin, superficial fluency.

    {#blank#}5{#/blank#}. Native-like fluency means that you generally know all the same words that a native knows and can speak at the same pace with the same amount of ease as a native speaker. You will likely have an accent, but as long as your conversation partner can understand you, it doesn't matter.

    Literary fluency is like graduating from native-like to educated-native-like fluency. It focuses on the more intellectual（知识性的） side of a language: indulging in literature, attending university, composing song lyrics, etc.

    There are a ton of other things that fluency could potentially（可能地） be, but that's up to you to figure out.

A. It sounds too good to be true.

B. However, Nobody is “perfectly fluent” in any language.

C. Quick fluency is good if you have some sort of deadline.

D. But have you ever considered what fluency really means?

E. But does fluency have the same meaning to other person as it does to you?

F. Unlike perfect fluency, native-like fluency is a reasonable and attainable goal.

G. To assist you in determining what fluency is, I'll describe a few different types of fluency.

    Shoppers in the UK are spending less money on toilet paper to save money, research has shown.

    Penny saving UK consumers choose cheaper products from discounters such as Aldi and Lidi rather than expensive alternatives.

    This has wiped 6% off the value of the soft tissue paper market in the UK. It has reduced from £1.19 billion in 2011 to £1.12 billion in 2015, according to a new report from market research company Mintel. Furthermore, the future of the market looks far from positive, with sales expected to fall further to £1.11 billion in 2016.

    In the last year alone, despite an increase in the UK population and a rise in the number of households, sales of toilet paper fell by 2%, with the average household reducing their toilet roll spending from £43 in 2014 to £41 in 2015.

Overall, almost three in five people say they try to limit their usage of paper – including facial tissue and kitchen roll    to save money. “Strength, softness and thickness remain the leading signs of toilet paper quality, with just a small part of consumers preferring more expensive alternatives, such as those with flower patterns or perfume,” said analyst Jack Duckett. “These extra features are considered unnecessary by the majority of shoppers, which probably reflects how these types of products are typically more expensive than regular toilet paper, even when on special offer.”

    While consumers are spending less on toilet paper, they remain particular about it when it comes to paper quality. One in 10 buyers rank toilet rolls made from recycled paper among their top considerations, clearly showing how overall the environment is much less of a consideration for shoppers than product quality. In a challenge for makers, 81% of paper product users said they would consider buying recycled toilet tissue if it were comparable in quality to standard paper.

    At a meeting of the State Council, China's Cabinet, on Tuesday, Premier Li Keqiang said it is important to keep the social insurance premium（保险费） policy stable（稳定）, which to a large extent has eased people's worries at a time when a new regulation on premium collection has aroused public concern.

    The general offices of the Communist Party of China Central Committee and the State Council recently issued a reform plan for tax collection, which includes pension, medical, unemployment, occupational injury and maternity insurance will be uniformly collected by the taxation authorities from Jan 1, 2019.

    In fact, the taxation authorities have been collecting social insurance premiums for more than one decade. Social insurance premiums in 19 provinces and regions are collected by the local taxation authorities.

    In particular, companies have expressed concern over the uniform collection of social insurance premium by taxation authorities mainly for three reasons.

First, the new regulation indicates the reform of the collecting system as a result of institutional reform of the State Council. The companies are worried especially because they believe compulsory collection of social insurance premium will increase their expenditure on social insurance.

    Second, since the taxation authorities are fully in charge of social insurance premium collection, the companies fear that the establishment of a new collection system will prevent enterprises escaping paying the social insurance premium.

    Third, the media have reported that lately the local authorities in provinces such as Jiangsu, Heilongjiang and Hubei have been ordering enterprises to pay the arrears （ 欠 款 ） in social insurance premium they should have paid in the past years.

    These factors have increased the companies' concern over the new premium-collection regulation. Some people assume the reform will increase the companies' cost, and some companies have even begun to lay off employees fearing that “winter is coming”.

    Thanks to the current premium-collection system, the companies have managed to not pay a huge amount of social insurance premium. Take urban workers' basic pension insurance for example. It is estimated that the companies have paid only about two-thirds of the total amount of social insurance premium. Calculating on the basis of the data for 2017, this year the actual social insurance premium collection is 3.34 trillion yuan ($487.71 billion), while the total amount should be 5.08 trillion yuan. The due amount is more than one-third of the total that should have been paid.

    Hot spots of drones (无人机) in Australia are getting sensors to automatically identify the aircraft and their pilots. Australia's Civil Aviation Safety Authority (CASA) said it would fix the equipment at the nation's airports starting next month. The monitors have been planned for some time, but come in the wake of 72 hours of drone-related disorder at the UK's Gatwick airport last week.

    In 2019, Australia will also start a scheme to register drone owners. The UK is also due to introduce a scheme in November that will require recreational drones weighing 250g (0.55lb) or more to be registered.

    Almost 140,000 air travellers were delayed last week after reports of drone sightings caused huge delays at Gatwick Airport. UK police are still searching for the criminals, although they have also raised the possibility that witness reports of the aircraft were mistaken. The incident “highlights” the need for a drone-spotting capability (能力), CASA spokesman Peter Gibson told the news agency Agence France-Presse. The supervision system would be able to spot the types of drone being flown, read their serial numbers and work out where the pilot was located, he said. Efforts to identify pilots would be aided by the introduction of the registration scheme for commercial and casual drone owners, he added. “2019 will witness severe action towards drone safety,” said Mr. Gibson. As well as airports and other sensitive locations, the drone-spotting systems will be fixed in other places known to be popular with drone owners such as the Sydney Harbour Bridge.

    Authorities in Australia have expressed worries about the number of drones being flown in controlled areas in recent months. Anyone breaking rules could face fines of up to 10,000 Australian dollars ($7,058; £5,600) as well as checks on the safety of their craft. “In 2019 it could be very expensive doing the wrong thing with your drone,” said Mr. Gibson. Events at Gatwick were discussed by ministers in a Christmas Eve phone conference. It is understood that the Cabinet Office “pushed” the Ministry of Defence and the Home Office to update their relevant regulations. They also discussed defence systems across the UK's airports.

    One of the most important aspects of an image is color. People are very sensitive to color, and different colors have different on people.

    In general, red is an exciting color, which creates an image of action, energy danger. Red is also the most frequently used color in flags. Eighty percent of the world's flags contain red. A study in Germany showed that football teams wearing red are more successful. Blue is a very calm color. Business executives usually wear dark blue suits. Blue is also a peaceful color. The flag of the United Nations is light blue. Yellow is associated with openness and freedom. Green is a very relaxing color. Surgeons nowadays wear green, because it's less tiring than white. Black creates an image of power and authority. It can also be a very threatening color. Gangsters and vampires often wear black, white is a pure and strong color. This is one reason why doctors wear white coats. We trust them more. Grey is a very anonymouscolor. People wearing grey don't want other people to notice them. Brown is the opposite of black. It's warm and friendly, while black is threatening

It is believed that Chinese knotting, also known as zhongguojie, originated for recording information and exchanging messages {#blank#}1{#/blank#} writing was invented. Over the past thousands of years, knots {#blank#}2{#/blank#} (play) an important part in the life of Chinese. {#blank#}3{#/blank#} (initial), Chinese knots acted as good -luck charms to drive away evil spirits. Today, Chinese knots are widely used to decorate homes during festivities.

A major characteristic of Chinese knots is that they are often tied from a single continuous length of string. The knots are commonly named {#blank#}4{#/blank#} the shape it takes. Chinese knots are created in a {#blank#}5{#/blank#} (various) of colors such as gold, green, blue, or black, though the most commonly used color is red, {#blank#}6{#/blank#} symbolizes good luck and prosperity.

Crafting the Chinese knot is a three-step process {#blank#}7{#/blank#} (involve) tying knots, tightening them and adding the finishing touches. The knots {#blank#}8{#/blank#} (pull) tightly together and are strong enough to be used for binding or wrapping, making them very practical.

Today, most of such knots are often mass manufactured in factories. Skilled knot artists weave complex knots that you might see {#blank#}9{#/blank#} (sell) as souvenirs that you can take back with you. If you have time, why not try your hand at it? Perhaps these age-old charms can add {#blank#}10{#/blank#} touch of good luck to your daily life?
