If you want to get the most out of the study of a language, you must also read for pleasure: novels, plays, travel books, and so on. And in reading books of this kind the important thing is to get on with reading; to try to grasp what the writer is going to tell you in the book as a whole. This is impossible if you stop and think over the meaning of every single word which happens to be unfamiliar. You can not enjoy a story if you stop half a dozen times on every page in order to look up words in the dictionary. You may even prevent yourself from understanding the story as a whole by doing this.

    When you are reading books of this kind, therefore, you will usually have to rely mainly on the context to help you. If you meet an unfamiliar word, do not let it take too much of your attention from the main thread(主线) of the story. In all probability you will meet the same word again a few pages later on in a slightly different context, and each time you see it that your understanding of it will become more exact.

    Mother's Day is a time of memory and celebration for Mom. The earliest Mother's Day celebrations date back to ancient Greece in honour of Rhea, the Mother of Gods. During the 1600s, England celebrated a day called “mothering Sunday”. Celebrated on the fourth Sunday of Lent(四旬斋)，“mothering Sunday” honoured the mothers England.

    During the time many of the England's poor worked as servants for the wealthy.AS most jobs were located far from their homes, the servants would live at the houses of their employers. On Mothering Sunday, the servants would have the day off and were encouraged to return home and spend the day with their mothers. A special cake, called the mothering cake, was often brought along.

As Christianity(基督教) spread throughout Europe, the celebration changed to honour the “Mother Church”—the spiritual power that gave them life and protected them from harm. Over time the church festival combined with mothering Sunday celebration. People began honouring their mothers as well as the church.

    In the United States Mother's Day was first suggested in 1872 by Julia Ward Howe as a day devoted to peace. Then in 1907 Ana Jarvis, from Philadelphia, began a campaign(运动) to establish a national Mother's Day. Ms Jarvis persuaded her mother's church in Grafton, Virginia to celebrate Mother's Day on the second anniversary of her mother's death, the 2nd day Sunday of May. By the next year Mother's Day was also celebrated in Philadelphia.

    Ms Jarvis and her supporters began to write to ministers, businessmen, and politicians demanding to establish a national Mother's Day. It was successful as by 1911 Mother's Day was celebrated in almost every state. President Woodrow Wilson, in 1914, made the official announcement that Mother's Day was a national holiday and it was to be held each year on the 2nd Sunday of May.

    While many countries of the world celebrate their own Mother's Day at different times throughout the year, there are some countries such as Denmark, Finland, Italy, Turkey, Australia, and Belgium which also celebrate Mother's Day on the 2nd Sunday of May.

    Imagine a brand-new, magical pill which can measurably improve your memory, overall cognitive (认知的) performance, ability to learn new information, mood, ability to handle problems and more. Would you buy it?

    Yeah, yeah, you saw this coming: That pill exists, but not in pill form. You can have all of those benefits for free, and all it takes is going to bed a little bit earlier. So what are we to do to get a better night's sleep?

    First, learn how much sleep you need. Generally, if you're waking up tired, you're not getting enough. However, the gold standard of eight hours per night might not be right for you. A study from 2015 brought into question whether we need that magical number, so following your body is the best way to figure out the right rhythm. The only real guideline is to get as much sleep as you need to feel refreshed and energized the next day.

    Next, figure out your body's natural rhythm. Maybe after years of trying, you need to acknowledge that you're just not a morning person. And that's perfectly fine! Click the link and take the quiz to find out what kind of sleeper you are, and don't fight your body's natural sleep tendencies.

    Last, keep a consistent sleep schedule. This can be the most important part of your overall sleep quality We're all equipped with circadian clock (生物钟), which s that internal 24-hour timer that naturally tells us when to sleep, and the best way to getting rest and feeling rested is to keep this consistent. Fall asleep and wake up at the same time every day, and try to build as much regularity into your schedule as possible. And don't forget to keep your bedroom cool.

    Babies have an astonishing talent that adults entirely lose. By the age of one, they can recognise the significant noises around them and group them into a language. When we have lost this capacity as adults, it becomes enormously difficult to distinguish between sounds that are glaringly different to a native speaker. It all sounds Greek to us. This is because the range of possible sounds that humans use to convey meaning may be as high as 2,000, but few languages use more than 100 and even then the significant noises－the phonemes (音素) of a language－each cover a range of sounds and so vague distinctions which would change the meaning of a word in other languages.

    But where do these phonemes come from and why do they shift over time? New research suggests that the apparently arbitrary distribution of some sounds around the world may be partially explained by diet. This is unexpected. We'd rather think of language as product of our thought  rather than of the arrangement of our teeth. In reality, though, any given language must be both.

    Hunter gatherer languages very seldom use the sounds known as labiodentals (唇齿音)－those such as f and v－that are made by touching the lower lip with the upper teeth. Only two of the hundreds of Australian aboriginal languages use them, for example. But in cultures that have discovered farming, these consonants (辅音) are much more common. The argument goes that farmers eat more cooked food and more dairy than hunter gatherers. Either way, they need to chew mush less, and to bite less with their front teeth. So farmers grew up with smaller lower jaws and more of an overbite than their ancestors who had to bite through harder foods. It became easier for them to make the labiodental consonants instead of purely labial (唇音) ones: one example is that f come to take the place of p. Romans said "pater" but English speakers (unless they're Rees－Moggs) say "father".

    Beyond these particular changes, the story highlights the way in which everything distinctively human is both material and spiritual: speech must combine sound and meaning, and the meaning can't exist or be transmitted without a real object. But neither can it be reduced to the purely physical, as our inability to understand or even to recognise foreign languages makes clear. The food we eat shapes our jaws, and our jaws in turn shape the sounds of our language. The ease with which we eat probably shapes our thought too, as anyone who has suffered toothache could testify. What we eat may have shaped the sounds of our language, but how we eat changes how we feel and what we use language to express. A family meal is very different from a sandwich at the office desk, even if the calorie is the same. Food has purposes and meanings far beyond keeping us alive and pleasing the Palate (味觉).

    In the US and Britain, the slogan around colleges was "Save water. Shower with a friend." Now, Wuhan University has come up with another system for the campus bathhouse. It charges students for the amount of time in a shower. Before entering the bathhouse, students pay for the amount of time they want in the shower with cash or their student ID card. The clock starts ticking the minute the tape is turned on. It pauses when a button is pressed for soap. An integrated circuit (IC) card reader at each tap shows the time. No money, no water. The benefits of the new system can be seen with the old system, which charged 1 yuan for each person regardless of time in the shower. The university used about 320 tones of water daily under the old system, but only 160 tons now.

    Many students use the new system but opinions on it are divided. Some students say it is bad because bathing had become a sort of race. Many people using it for the first time are not sure how long they need to shower. Some might be embarrassed if their time is up and they're still covered in soap. They have to ask the bathhouse worker to help them buy extra time.

    "It's a flaw in the system that you can not buy extra time on the ID card," said Ren, a freshman in Wuhan University. The university is also considering some students' suggestions that they be allowed to pay after they've finished the shower. Not surprisingly, some are complaining about losing the hour shower. But many students say the move helps them develop a water-saving sense.

    Without the time limits, most students tended to shower for 30 to an hour in the bathhouse.

    Some even used the hot water to wash their clothes. "In my experience, 10-20 minutes is enough," said Dai Zhihua, a third-year student who usually takes 8 minutes.

    A similar system has been installed in other universities. Shanghai Normal University introduced it at its Fengxiang Campus in September. The bathing fee there is 0.2 yuan per minute. One male student responded by setting a record with a two-minute shower.
