It was in the Victorian Era(维多利亚时期) that the novel became the leading form of literature in English. Most writers were more concerned to meet the tastes of the middle class. The best known works of the period included the works of Charles Dickens and the Bronté sisters and others.

    Charles Dickens came on the literary scene in the 1830s. Dickens wrote vividly about London life and the struggles of the poor. Most of his works were written in a very humorous style, which was popular with readers of all classes.

    The Bronté sisters were English writers of the 1840s and 1850s. They began to write from early childhood. In 1846 they published the first book at their own expense as poets; however, their book attracted little attention, selling only two copies. Then the sisters turned to writing novels, each producing a novel in the following year.

    An interest in rural matters and the changing social and economic situation of the countryside may be seen in the novels of Thomas Hardy and a number of others.

    Literature for children developed as a single style. Some works became well-known, such as those of Lewis Carroll and Edward Lear. Adventure novels were written for adults but are now generally grouped in the list for children. Helen Beatrix Potter was an English author at the end of the Victorian Era, best known for her children's books, which featured animal characters. In her thirties, Potter published the highly successful children's book The Tale of Peter Rabbit in 1902.

     “I see you've got a bit of water on your coat,” said the man at the petrol station. “Is it raining out there?”“No, it's pretty nice,” I replied, checking my sleeve. “Oh, right. A pony(马驹) bit me earlier.”

As it happened, the bite was virtually painless: more the kind of small bite you might get from a naughty child. The pony responsible was queuing up for some ice cream in the car park near Haytor, and perhaps thought I'd jumped in ahead of him.

    The reason why the ponies here are naughty is that Haytor is a tourist-heavy area and tourists are constantly feeding the ponies foods, despite sighs asking them not to. By feeding the ponies, tourists increase the risk of them getting hit by a car, and make them harder to gather during the area's annual pony drift(迁移).

    The purpose of a pony drift is to gather them up so their health can be checked, the baby ones can be stooped from feeding on their mother's milk, and those who've gone beyond their limited area can be returned to their correct area. Some of them are also later sold, in order to limit the number of ponies according to the rules set by Natural England.

    Three weeks ago, I witnessed a small near-disaster a few mils west of here. While walking, I noticed a pony roll over on his back. “Hello!” I said to him, assuming he was just rolling for fun, but he was very still and, as I got closer, I saw him kicking his legs in the air and breathing heavily. I began to properly worry about him. Fortunately, I managed to get in touch with a Dartmoor's Livestock Protection officer and send her a photo. The officer immediately sent a local farmer out to check on the pony. The pony had actually been trapped between two rocks. The farmer freed him, and he began to run happily around again.

    Dartmoor has 1,000 or so ponies, who play a critical role in creating the diversity of species in this area. Many people are working hard to preserve these ponies, and trying to come up with plans to find a sustainable(可持续的) future for one of Dartmoor's most financially-troubled elements.

    Staying up late is a potential battle between parents and kids. But the solution could be as simple as changing your meal time.

    Researchers at the University of Surrey, UK, found that delaying (延迟) meals could help change one of the internal (内部的) body clocks. Besides a “master” clock in the brain, there are clocks in other parts of the body. They are usually synchronized (同步的) according to factors including light.

    During the study, researchers tested 10 participants to study the effect of changing meal times on their body clocks. The participants were given three meals – breakfast, lunch and dinner. In the first stage, participants received breakfast 30 minutes after waking. Lunch and dinner followed, after 5-hour intervals (间隔). In the second stage, each meal was delayed by 5 hours. Right after each stage, blood and fat samples (样本) were collected.

    Results showed that later meal times greatly influenced blood sugar levels. A 5-hour delay in meal times caused a 5-hour delay in the internal blood sugar rhythms (规律性变化).

    The discovery showed that meal times are in line with (与……一致) the body clock that controls blood sugar levels.

    This is a small study but the researchers believed the findings could help jet lag (飞行时差反应) sufferers and night-shift (夜班的) workers.

    In a study by the University of Surrey in 2013, researchers explored what happened when a person's body was changed from a normal pattern to that of a night-shift worker's.

    After people work through the night, over 97 percent of the body's rhythmic genes are disrupted (扰乱).

    These findings explain why we feel so bad following a long flight, or after working at night, according to Simon Archer, one of the study's researchers.

    “It's like living in a house. There's a clock in every room in the house and in all of those rooms those clocks are now disrupted, which of course leads to chaos (混乱) in the household,” fellow researcher Derk-Jan Dijk told the BBC.

    Changing meal times didn't affect the “master” body clock – the one controlling when we get sleepy – but it can reset the body clock that controls blood sugar levels.

    This wouldn't necessarily cure jet lag completely, but it might reduce the negative effects.

    A study published earlier this year suggested that just a weekend camping trip could be enough to reset our body clocks. And now this latest research shows regular food schedules could play a key part too.

    I was very excited on the first day of high school! I had P.E for the first period. We hurriedly gathered in the locker room (衣帽间) when the headmaster began to speak, “Good morning, boys and girls! Welcome to the first day of the great new school year. We will begin with the pledge (誓言) of loyalty.”

    I pulled my shirt over my head and my right hand immediately rested over my heart. A few tears came to my eyes as every time I pledged. I thought of my grandpa. He had died almost a year before, but I still missed him every day. Grandpa served in World War II and the flag had a very special meaning for him.

    The next morning in the locker room, I noticed something strange. Some girls talked through the pledge. After that, even fewer did the pledge, including the teachers. By the second week of school, I was the only girl in the whole locker room that did the pledge.

    The next morning, I hid in the bathroom to change clothes and pledge. There I couldn't see the flag and I had a sense of sorrow to be hiding like that. I kept hiding for the next week and felt worse.

    I spent a weekend gathering up my nerve. On Monday, I changed into my gym clothes right away and was standing by my locker when the headmaster began morning announcements. The pledge started and I put my hand over my heart. A girl nearby locked her locker and asked, “Why are you doing that? ” She looked confused.

    “My grandpa fought in World War II and he died last year,” I said. “I'm doing it for him.”

    She felt embarrassed and looked away. “Oh.” She said.

    Over the next few weeks, more girls questioned me about the pledge. I gave them all that same answer. I never inspired other girls to do the pledge along with me. They made their choice; I made mine. I was doing it for my Grandpa, but more than that, I was doing it for myself. Grandpa raised me to be proud of my country and that pride didn't stop.

    Despite what so many people would love to believe，NASA hasn't discovered any evidence of past or present intelligent life on Mars. Therefore, when the Curiosity rover  (好奇号探测器)found something suspicious on the Red Planet's surface, they were not only surprised but also a little bit worried.

    The thin fragment (碎片)was suspicious enough to guarantee its own name, with NASA's Curiosity rover team calling it the “Pettegrove Point Foreign Object Debris，” named for where it was discovered. With no idea what it was or where it came from, the rover's handlers began to worry that it might actually be a piece of the rover itself，suggesting some unseen damage or other issue with the robot. Thankfully，those concerns seem to have been unfound.

    In a new update from NASA the object has now been identified as a natural piece of rock rather than a piece of any man-made craft or vehicle. The team analyzed the unusual object with a tool called the Chem Cam RMI. The instrument uses a laser (激光器)to sniff out the makeup of anything that is pointed at, and the results for this particular piece of debris revealed that it's actually just a very thin piece of rock.

    NASA describes the inspection: The planning day began with an interesting result from the previous plan's Chem Cam RMI analysis of a target that was referred to as “Pettegrove Point Foreign Object Debris”(PPFOD)，and supposed to be a piece of spacecraft debris fact. In fact it was found to be a very thin slice of rock, so we can all rest easy tonight. Curiosity has not begun to shed its skin!

    How this particularly thin sliver of rock got to where it is—and why it seems to be a different colour than the surrounding sand and debris—remains unexplained, but at least the rover isn't falling apart.
