    Schedule it.{#blank#}3{#/blank#}This should include meetings, tasks, and deadlines. Assign each person a color and highlight each task with those colors, so it's clear who is doing what.

    Every day millions of letters go from one country to another. Letters mailed in Italy are received in Japan. Letters mailed in Canada are received in Africa. On the letters there are many different kinds of stamps, bought in different countries.

    The Universal Postal Union helps each letter get to the right place as quickly as possible. It sets up rules about the size and weight of letters, postcards, and small packages. It has rules that all countries must follow about international postal rates.

    On hundred years ago international mail did not move so smoothly. One country did not always accept another country's letters. Letters from some countries were too large to fit into the mailboxes of other countries. Letters traveled by many different routes. Some were lost along the way.

    Sometimes the person who sent the letter could pay only part of the postage. The person receiving the letter had to pay the rest.

    Do you love holidays but hate the fact that you put on weight (增加体重) after the holidays? You are not alone.

    Holidays are happy days with pleasure and delicious foods. Many people, however, are worried about the weight that comes along with these delicious foods.

    With proper planning, it is possible to control your weight. The idea is to enjoy the holidays but not to eat too much. You don't have to turn away from the foods that you enjoy. The following suggestions may help you.

    Do not miss meals. Before yon leave home for a feast(宴会), have a small, low-fat snack. This may help to keep you from getting too excited before delicious foods.

    Begin with clear soup, fruit or vegetables.

    A large glass of water before you eat may help you feel full.

    Use a small plate; a large plate will encourage you to have more than enough.

    Better not have high-fat foods. Dishes that look oily or creamy have much fat in them.

    Choose lean（瘦的） meat. Fill your plate with salad and green vegetables.

    If you have a sweet tooth, try mints (薄荷) and fruits. They don't have fat content as cream and chocolate.

    Don't let exercise take a break during the holidays. A 20-minute walk after a meal can help burn off excess calories (多余的热量).

China's Tianwen 1 Mars probe (探测器) conducted its fourth orbital correction on Friday evening, as the spacecraft makes ready for its arrival in orbit around Feb. 10, according to the China National Space Administration.

The name comes from the long poem Tianwen, meaning Heavenly Questions or Questions to Heaven, written by Qu Yuan, one of the greatest poets of ancient China. In Tianwen, this name conveys the Chinese nation's steady effort in pursuing truth and culture of exploring nature and the universe. CNSA also unveiled (发布) the logo of China's planetary exploration missions, featuring the letter C, signifying China, international cooperation and capacity of entering space.

Tianwen I has flown for 197 days and more than 465 million kilometers on its journey to the planet. It is now around 184 million km from Earth and I. I million km from Mars. Depending on the two planets' orbits, Mars is between 55 and 400 million km from Earth. Mars probe Tianwen I is seen in its first selfies in space on Oct. 1, 2020. The administration also published a black-and-white picture of Mars taken by Tianwen I, the first snapshot (抓拍的照片) from the Chinese craft.

Tianwen I, the country's first independent Mars mission, was launched by a Long March 5 heavy-lift carrier rocket on July 23 from the Wenchang Space Launch Center in Hainan province, kicking off the nation's planetary exploration program.

A successful landing would make China only the second nation to place a spacecraft on the Martian planet. China would also be the first to successfully orbit, land and deploy (部署) a vehicle in the same mission. According to experts, searching for signs of life on Mars will be the first and foremost scientific goal. China is open and inclusive in the development of its space technology not least because it believes that the exploration of outer space should help build a community with a shared future for mankind.

When adult humans meet a baby, many can't help speaking in a higher-pitched (更高音的) and sing-song y voice. This shift, known as parentese, is not unique to humans. It has also been observed in animals like monkeys and gorillas. Now, scientists are adding one more species to that list: bottle-nose dolphins.

Dolphins are intelligent animals that live and hunt in groups. They communicate in a unique way: Every individual produces its own signature sound that acts much like an ID card, usually by its first birthday. But how does each come up with its distinctive whistle? For babies, it might have something to do with listening to Mum. To solve this mystery, researchers examined the sounds mother dolphins make.

Scientists studied 34 years' worth of recordings of sounds made by 19 female bottle-nose dolphins. When the mother dolphins were near their young, they continued to make their signature sounds, but at a higher frequency. They also used a wider range of frequencies than they did when their babies were not nearby.

This discovery suggests that using these modifications, mother dolphins assist their young in learning how to produce these calls themselves. Since baby dolphins often spend some years with their mothers before living on their own, it makes sense that this adaptation would help them learn to communicate. At the very least, the higher-pitched whistle likely gets the babies' attention. "It's important for a baby to know, ‘Oh, Mum's talking to me now,'" says marine biologist Janet Mann.

This kind of research could help us understand how language developed in humans. "It is absolutely essential to have basic knowledge about other species and how they communicate," says Mann. "I would be really interested to see whether dolphins also change their sounds when interacting with babies of others, which is what happens in humans."
