英语翻译1.I have never understood why so many people visit Rome from late spring to early autumn,when traffic,heat and stressed shopkeepers and waiters lead to the lower tone of the city2.In winter,the colors are more vivid and the low-flying sun turns Rome into a wonderful stage set.3.Perhaps the only period you might want to avoid is the two weeks before Christmas.Christmas in Rome is an important family event.4.If you're lucky with the weather,it's in January and February that Rome is at its best.This is also a good time of year to find accommodation bargains.
1.我一直不能理解为什么那么多人总喜欢在春末到初秋这段时节去罗马旅游参观,这段时节是交通繁忙、气温炎热和店主店员们充斥只压抑和无力的时节,这使整个罗马成为一个没有趣味,低迷的城市.2.在冬天时,城市的颜色是明艳的,太阳低低地悬浮在它的上空,这使罗马富有了不可思议的舞台剧般的色彩.3.也许在整个(冬天)时节中你唯一不想经历的就是圣诞节的前两周.圣诞节是罗马人一个非常重大的家庭节日.4.如果在天气方面你是一个幸运儿的话,罗马在1月到2月这两个月中天气是最棒的,这同时也是一年当中食宿方面最优惠的两个月.
I expect the pallet is reliable, and will not cause any damage to the goods during transportation. 注:货物托盘 - pallet 质量可靠 - reliable
1 我从不理解为什么从晚春到早秋有这么多的人到罗马旅游,当交通,气温和压力极大的店家与服务员导致城市的状态下降时。the sun rises late and sets early in winter.这里为什么set和rise要加s_百度知道

December solstice 2015 comes on Tuesday, December 22 at 4:48 UTC.
Celebration time!
Sunlight on Earth, on the day of the winter solstice.
The north polar region of Earth is in 24-hour darkness, while the south polar region is in 24-hour daylight.

Late dawn. Early sunset. Short day. Long night. For us in the Northern Hemisphere, the December solstice marks the longest night and shortest day of the year.
Meanwhile, on the day of the December solstice, the Southern Hemisphere has its longest day and shortest night.
This special day is coming up on Tuesday, December 22 at 4:48 UTC (December 21 at 10:48 p.m. CST).
No matter where you live on Earth’s globe, a solstice is your signal to celebrate.

Day and night sides of Earth on the December 2015 solstice
Day and night sides of Earth at the instant of the December 2015 solstice (2015 December 22 at 4:48 Universal Time). Note that the north polar region of Earth must endure 24 hours of night, while the south polar region gets to bask in 24 hours of daylight. Image credit:
When is the solstice where I live?
The solstice happens at the same instant for all of us, everywhere on Earth.
In 2015, the December solstice comes on December 21 at 10:48 p.m. CST.
That’s on December 22 at 4:48 .
It’s when the sun on our sky’s dome reaches its farthest southward point for the year.
At this solstice, the Northern Hemisphere has its shortest day and longest night of the year.
To find the time in your location, you have to translate to your time zone.
Just remember: you’re translating from 4:48 UT on December 22. So for most of the world’s eastern hemisphere – Europe, Africa, Asia, Australia and New Zealand – the December solstice actually comes on December 22. For example, if you live in Perth, Australia, you need to add 8 hours to Universal Time to find out that the solstice happens on December 22, at 12:48 p.m. AWST (Australian Western Standard Time).
Earth has seasons because our world is tilted on its axis with respect to our orbit around the sun.

What is a solstice?
The earliest people on Earth knew that the sun’s path across the sky, the length of daylight, and the location of the sunrise and sunset all shifted in a regular way throughout the year.
They built
– or, for example, at
– to follow the sun’s yearly progress.
But we today see the solstice differently.
We can picture it from the vantage point of space.
Today, we know that the solstice is an astronomical event, caused by Earth’s tilt on its axis, and its motion in orbit around the sun.
Because Earth doesn’t orbit upright, but is instead tilted on its axis by 23-and-a-half degrees, Earth’s Northern and Southern Hemispheres trade places in receiving the sun’s light and warmth most directly.
The tilt of the Earth – not our distance from the sun – is what causes winter and summer.
At the December solstice, the Northern Hemisphere is leaning most away from the sun for the year.
At the December solstice, Earth is positioned in its orbit so that the sun stays below the north pole horizon.
As seen from 23-and-a-half degrees south of the equator, at the imaginary line encircling the globe known as the Tropic of Capricorn, the sun shines directly overhead at noon. This is as far south as the sun ever gets.
All locations south of the equator have day lengths greater than 12 hours at the December solstice. Meanwhile, all locations north of the equator have day lengths less than 12 hours.
For us on the northern part of Earth, the shortest day comes at the solstice.
After the winter solstice, the days get longer, and the nights shorter.
It’s a seasonal shift that nearly everyone notices.
Around the time of the winter solstice, watch for late dawns, early sunsets, and the low arc of the sun across the sky each day.
Notice your noontime shadow, the longest of the year.
Meanwhile, at the summer solstice, noontime shadows are short.

Where should I look to see signs of the solstice in nature?
Everywhere.
For all of Earth’s creatures, nothing is so fundamental as the length of daylight. After all, the sun is the ultimate source of all light and warmth on Earth.
If you live in the northern hemisphere, you can notice the late dawns and early sunsets, and the low arc of the sun across the sky each day. You might notice how low the sun appears in the sky at local noon. And be sure to look at your noontime shadow. Around the time of the December solstice, it’s your longest noontime shadow of the year.
In the Southern Hemisphere, it’s opposite.
Dawn comes early, and dusk comes late.
The sun is high.
It’s your shortest noontime shadow of the year.
friend John Michael Mizzi saw this sunset from the island of Gozo (Malta), south of Italy.
The earliest sunsets come a couple of weeks before the winter solstice.
Why doesn’t the earliest sunset come on the shortest day?
The December solstice marks the shortest day of the year in the Northern Hemisphere and longest day in the Southern Hemisphere.
But the earliest sunset – or earliest sunrise if you’re south of the equator – happens before the December solstice.
Many people notice this, and ask about it.
The key to understanding the earliest sunset is not to focus on the time of sunset or sunrise.
The key is to focus on what is called true solar noon – the time of day that the sun reaches its highest point, in its journey across your sky.
In early December, true solar noon comes nearly 10 minutes earlier by the clock than it does at the solstice around December 22.
With true noon coming later on the solstice, so will the sunrise and sunset times.
It’s this discrepancy between clock time and sun time that causes the Northern Hemisphere’s earliest sunset and the Southern Hemisphere’s earliest sunrise to precede the December solstice.
The discrepancy occurs primarily because of the tilt of the Earth’s axis. A secondary but another contributing factor to this discrepancy between clock noon and sun noon comes from the Earth’s elliptical – oblong – orbit around the sun. The Earth’s orbit is not a perfect circle, and when we’re closest to the sun, our world moves fastest in orbit.
Our closest point to the sun – or perihelion – comes in early January.
So we are moving fastest in orbit around now, slightly faster than our average speed of about 30 kilometers (18.5 miles) per second. The discrepancy between sun time and clock time is greater around the December solstice than the June solstice because we’re nearer the sun at this time of year.

The precise date of the earliest sunset depends on your latitude.
At mid-northern latitudes, it comes in early December each year.
At northern temperate latitudes farther north – such as in Canada and Alaska – the year’s earliest sunset comes around mid-December. Close to the Arctic Circle, the earliest sunset and the December solstice occur on or near the same day.
By the way, the latest sunrise doesn’t come on the solstice either.
From mid-northern latitudes, the latest sunrise comes in early January.
The exact dates vary, but the sequence is always the same: earliest sunset in early December, shortest day on the solstice around December 22, latest sunrise in early January.
And so the cycle continues.
Bottom line:
In 2015, the December solstice comes on December 21 at 10:03 p.m. CST.
That’s December 22 at 4:48 .
It marks the Northern Hemisphere’s shortest day (first day of winter) and Southern Hemisphere’s longest day (first day of summer). Happy solstice, everyone!
