Gnocchi (['noki] or ['njoki]; singular gnocco) are various thick, soft dumplings that may be made from semolina, ordinary wheat flour, flour and egg, flour, egg, and cheese, potato, breadcrumbs, or similar ingredients.

Common accompaniments of gnocchi include melted butter (sometimes fried butter) with sage, pesto, and various sauces. In cuisine, an omelette ['omlit] or omelet 西式鸡蛋饼 is a dish made from beaten eggs 打散的鸡蛋 quickly cooked with butter or oil in a frying pan, sometimes folded around a filling such as cheese, vegetables, meat (often ham), or some combination of the above. To obtain a fluffy texture, whole eggs or sometimes only egg whites are beaten with a small amount of milk or cream, or even water, the idea being to have "bubbles" of water vapour trapped within the rapidly cooked egg. Some home cooks add baking powder to produce a fluffier omelette; however, this ingredient is sometimes viewed unfavourably by traditionalists. 5.

Low-lying muddy land that is covered at high tide and exposed at low tide. wiki: Mudflats or mud flats, also known as tidal flats, are coastal wetlands that form when mud is deposited by tides or rivers. They are found in sheltered areas such as bays, bayous, lagoons, and estuaries. Mudflats may be viewed geologically as exposed layers of bay mud, resulting from deposition of estuarine silts, clays and marine animal detritus. Most of the sediment within a mudflat is within the intertidal zone, and thus the flat is submerged and exposed approximately twice daily. In the past tidal flats were considered unhealthy, economically unimportant areas and were often dredged and developed into agricultural land. Several especially shallow mudflat areas, such as the Wadden Sea, are now popular among those practising the sport of mudflat hiking. 10. goer ['gəuə] n I. a person who attends something regularly. filmgoer.

"Sydney is turning into a beast unto itself," Mr Christopher said. "We have strong conviction that the ABS will record 15 - 20 per cent house prices for the year in that city." JP Morgan economist Tom Kennedy, however, is less bullish乐观的 on Sydney, predicting 2014 house price growth at a similar level to Melbourne. "We certainly forecast price growth, but more around the 5 per cent mark," Mr Kennedy said. "It would be very hard to say that Sydney will register double digit growth and we are more conservative." "There's a lot of talk of overheating过热, but we don't think that's the case. Credit is low and prices are the only thing that's going higher," Mr Kennedy said. 15.

You mentioned this is life-changing for him, and it has been that and then moreso( 更甚于此, 尤甚于此. Though the phrase more so is conventionally spelled as two words, the one-word moreso gained ground in the late 20th century and continues to appear despite the disapproval of usage authorities and of spell check. More so strictly means that to a greater degree, and so recalls an adjective or adverb used earlier. For example, in the sentence, "Gina is studious, and Eleanor is more so," so recalls指代 the adjective studious, and so is a crucial element 关键元素 of the sentence while more is not. We could change more to less or equally, for instance, and the sentence would still make sense. So because more and so function separately, changing more so to moreso in cases like this is difficult to justify. But more so is used in several other ways, some of which are not strictly logical. Consider this example: It's not that Badet wasn't happy for his peers. More so(= even more, rather), he couldn't understand why he was being overlooked. Here, so does not recall an earlier word, and more and so do not perform separate functions. They work together as an adverbial phrase similar to even more or rather. If we accept this use of more so—and we have no choice, because it's common—there's no reason we shouldn't accept the compound moreso in its place. In fact, accepting moreso as an adverb synonymous with even more or rather takes care of any quibbles we might have over so's lack of antecedent.). It's just incredible what this guy has gone through in the last four months.

Miley Cyrus, 20, and Liam Hemsworth, 23, have ended their relationship and called off their engagement, reps for both stars have confirmed for USA TODAY. The buzz has long been brewing发酵, but now it's official. E! News reports that the split was "Miley's decision, after coming to grips with Liam being what she believed was less than faithful to her." People.com says the two have been "living separate lives." The couple – who met on the movie set of 2010's The Last Song – got engaged in May 2012. But there has been buzz for months that the relationship was on the rocks触礁. In April, rumors surfaced that the wedding had been postponed. All of it comes amid an Us Weekly report that Hemsworth was texting January Jones, with whom he had been linked at an Oscar party in March. His rep called that report a "fabrication编造, 胡编烂造."
"追尾, 尾随"相关: 1. tail I. Informal To follow: tailed after the leader. tailgate I. To drive so closely behind (another vehicle) that one cannot stop or swerve with ease in an emergency. Tailgating is the practice of driving on a road too close to a frontward vehicle, at a distance which does not guarantee that stopping to avoid collision is possible. Approximately one third of rear-end collisions involve tailgating. II. Slang To follow closely behind (another person), as in gaining access to an area requiring the use of an electronic identification card. To describe the act of an unauthorized person who follows someone to a restricted area without the consent of the authorized person, the term tailgating is also used. wiki: "Tailgating" implies without consent (similar to a car tailgating another vehicle on the freeway), while piggybacking usually implies consent of the authorized person. Tailgating can occur because of a lack of perceived risk in so doing. Thus, it is done unconsciously or negligently, very often by people who consider themselves safe drivers and generally obey the other rules of the road. In its worst form, it can be a particularly violent form of road rage and a form of intimidation. An example would be where the tailgating driver (the driver in the following vehicle) threatens damage to the leading vehicle and its occupants by driving aggressively — perhaps also with use of headlights and horn — to bully the leading vehicle's driver to get out of the way. A form of deliberate tailgating known as slipstreaming, "draft-assisted forced stop", or "draft-assisted forced auto stop" (D-FAS) is a technique which has been used by people known as hypermilers to achieve greater fuel economy. D-FAS involves turning off the engine and gliding滑行 in neutral while tailgating a larger vehicle, in order to take advantage of the reduced wind resistance in its immediate wake. Note that this practice is extremely dangerous: while tailgating itself is inherently risky, the danger of collision is increased with D-FAS as power for power brakes can be lost after a few applications of the brake pedal and, with older cars, the pressure that causes power steering to function can be lost as well. 2. In security, piggybacking 尾随入内 refers to when a person tags along with another person who is authorized to gain entry into a restricted area, or pass a certain checkpoint. The act may be legal or illegal, authorized or unauthorized, depending on the circumstances. However, the term more often has the connotation of being an illegal or unauthorized act. To describe the act of an unauthorized person who follows someone to a restricted area without the consent of the authorized person, the term tailgating is also used. "Tailgating" implies without consent (similar to a car tailgating another vehicle on the freeway), while "piggybacking" usually implies consent of the authorized person. Piggybacking came to the public's attention particularly in 1999, when a series of weaknesses were exposed in airport security. While a study showed that the majority of undercover agents attempting to pass through checkpoints, bring banned items on planes, or board planes without tickets were successful, piggybacking was revealed as one of the methods that was used in order to enter off-limits areas禁区(restricted areas 限制区域). 3. rear-end accident or rear-end collision: Who is at fault in rear-end collisions? If only 2 cars are involved in the accident, the car which hits from behind is liable in most circumstances. In 3 or more car pile-ups, it is necessary to determine whether the car immediately behind hit first or whether it had stopped in time and was pushed by the car behind it. If the latter case can be clearly determined then the car at the rear is responsible. In situations where a car rolls back into a stationary vehicle behind, it is the front car that is liable regardless of how close the rear vehicle was behind. In the absence of any independent witnesses however, it is often difficult to prove a situation such as this, unless the owner of the forward vehicle willingly admits liability. 4. A rear-end collision (often called simply rear-end or in the UK a shunt( I. To turn or move aside or onto another course: shunting traffic around an accident. II. To evade by putting aside or ignoring: urgent problems that society can no longer shunt aside. III. 扳道. To switch (a train or car) from one track to another. to shift (railroad rolling stock) from one track to another; switch.) ) is a traffic accident wherein a vehicle (usually an automobile or a truck) crashes into the vehicle in front of it. Common factors that contribute to rear-end collisions include by driver inattention 不留神, 不小心 or distraction, tailgating, panic stops, and reduced traction due to weather or worn pavement. It may also be a rail accident wherein a train runs into the rear of a preceding train. Typical scenarios for rear-ends are a sudden deceleration by the first car (for example, to avoid someone crossing the street) so that the following car does not have the time to brake and collides with the first. Alternatively the following car may accelerate more rapidly than the leading (for example, leaving an intersection) resulting in a collision. As a rule of thumb, if the two vehicles have similar physical structure, crashing into another car is equivalent to crashing into a rigid surface (like a wall) at half of the closing speed. This means that rear-ending a stationary car while travelling at 50 km/h (30 mph) is equivalent, in terms of deceleration, to crashing into a wall at 25 km/h (15 mph). The same is true for the vehicle crashed into. However if one of the vehicles is significantly more rigid (e.g. the rear of a truck) then the deceleration is more typically reflected by the full closing speed for the less rigid vehicle. A typical medical consequence of rear-ends, even in case of collisions at moderate speed, is whiplash ( ['wip,læʃ] I. The lash of a whip. II. an abrupt snapping motion resembling the lash of a whip. An injury to the cervical spine caused by an abrupt jerking motion of the head, either backward or forward. ). In more severe cases permanent injuries, e.g. herniation, may occur. The rearmost passengers in minivans benefit little from the short rear crumple zone, so they are more likely to be injured or killed in a rear-end collision. For purposes of insurance and policing, the driver of the car that rear-ends the other car is almost always considered to be at fault due to not leaving enough stopping distance or lack of attention. An exception to this rule comes into play if the rear-ended vehicle is in reverse gear. If the driver of the car that was rear-ended files a claim against the driver who hit him, said driver could be responsible for all damages to the other driver's car. 5. A tailwind顺风 is a wind that blows in the direction of travel of an object, while a headwind顶风 blows against the direction of travel. A tailwind increases the object's speed and reduces the time required to reach its destination, while a headwind has the opposite effect. Tailwinds and headwinds are commonly measured in relation to the speed of vehicles — commonly air and watercraft — as well as in running events — particularly sprints. In aeronautics, a headwind is favorable in takeoffs and landings because an airfoil moving into a headwind is capable of generating greater lift than the same airfoil 机翼, 螺旋桨 moving through tranquil平静的 air or a tailwind at equal ground speed. As a result, aviators and air traffic controllers commonly choose to take off or land in the direction of a runway that will provide a headwind. In sailing, a headwind may make forward movement difficult, and necessitate tacking into the wind.
