Do you love holidays but hate the increase weight that follows? 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, though, 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 be of some help to you.

    Do not miss meals. Before you leave home for a feast(宴会),have a small, low-fat snack(小吃). This may help to keep you from getting too excited before delicious foods. Begin with clear soup and 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 meat(瘦肉 ).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(过多的) calories.

    HONG KONG-Cross-border buses operated by Hong Kong companies on Friday started trial runs on the Hong Kong-Zhuhai-Macao Bridge (HZMB) in preparation for the bridge's upcoming opening.

    "The trial runs, arranged by the governments of the Chinese mainland, the Hong Kong Special Administrative Region (SAR) and the Macao SAR, would last for three days and aimed at testing the readiness of boundary crossing facilities (设施) of the three places," the Hong Kong SAR government's Transport and Housing Bureau told Xinhua.

    Two major cross-boundary coach trade associations in Hong Kong were invited to send buses and members to participate in the trial runs.

    Freeman Cheung, secretary of Hong Kong Guangdong Boundary Crossing Bus Association, said his association would run one bus with about 10 passengers on Friday and Saturday respectively as part of the trial runs.

    "Our bus started at noon from the Hong Kong Boundary Crossing Facilities and ran all the way to Zhuhai in about 40 minutes," he said, adding that "the journey was smooth."

    Alan Chan, secretary of another trade association who participated in the trial runs as a passenger, said the clearance procedures at boundary crossing facilities of the three places all went on well and smoothly.

    "The boundary crossing facilities of Zhuhai and Macao, in particular, are operated in a collaborative (合作的) way, which helps remarkably shorten the time needed for the clearance procedures," he said.

    The HZMB, situated at the waters of Lingdingyang of Pearl River Estuary, is a mega-size sea crossing linking the Hong Kong SAR, Zhuhai city of Guangdong Province and the Macao SAR.

    The 55-km bridge is the longest bridge-and-tunnel (隧道) sea crossing in the world.

    The bridge is meant to meet the demand of passenger and freight land transport among Hong Kong, the Chinese mainland and Macao, and to establish a new land transport link between the east and west banks of the Pearl River.

A kind of blue dye (颜料) called folium had been widely used to paint pictures on the pages of manuscripts (手稿) created in the Middle Ages. But long ago, this watercolor fell out of use.

"Manuscripts are an important part of the cultural works of art in the Middle Ages," said scientist Maria in an email to CNN. "Color is a basic feature of these manuscripts. To let ancient manuscripts. keep a good condition for future generations, we sometimes need to repaint their inside pictures through the ancient dye — like folium — that was once used in these manuscripts. But everyone who knew how to prepare folium had died long ago. So 'I led a team to study this dye."

Her team turned to books from the 1400s and found one that described the plant that was its source. It is a tiny plant with silvery-green leaves. Days later, the scientists reached a village in south Portugal, where nobody knew this little plant. However, after carefully going through a plenty of different plants growing there, the scientists finally raked out the plant they wanted and brought some back to their laboratory.

Back in the lab, the scientists produced the dye with the help of an ancient text on colors. The text has clearly described the ways to make it. "It's cool to have done that work of looking in the historical records and traveling back in time," says Casadio, who was not part of this study. It recreates an ancient process. By making the dye, the scientists could study its chemistry without experimenting on priceless delicate (易损的)  works of art, she points out.

Now, the researchers don't know the dye's stability(稳定性)and its ability against the environment that may wear and break it down over time. "To know such information is necessary if we desire to make these colors last long enough," Maria said. "So our study will continue."
