Waiting for a bus can be very{#blank#}1{#/blank#} (annoy). Often you{#blank#}2{#/blank#} (be) at the bus stop for half an hour, and the bus still hasn't come. {#blank#}3{#/blank#}, people in Zhongshan, Guangdong don't have to suffer this. It's all because of a mobile APP, Zhongshan Real-time Buses. With the APP, people can find out the exact time a bus arrives and set an alarm to remind {#blank#}4{#/blank#}to go to the bus stop in time.

    Five Senior 1 students make the APP possible. At first, they just wanted to add or change bus lines to help make it{#blank#}5{#/blank#} (easy) for students at their school to take buses. But later, they wanted to make something that is{#blank#}6{#/blank#}（benefit) to all the people of Zhongshan. {#blank#}7{#/blank#} (get) technical support, the team turned to the local public transportation group company. They carried out three surveys by collecting questionnaires {#blank#}8{#/blank#} are completed by about 600 people in shopping malls and bus stops. “The work took{#blank#}9{#/blank#} almost all of our spare time for four months,” said Su Yinan, 16.

    On Feb 25, Zhongshan Real-time Buses was born. It now covers over 100 bus lines in the city and has been downloaded more than 60,000 times. The project won the first place on the Fifth National High School Students Leadership Convention this summer.

    “We are very happy that Zhongshan people are using the results of our efforts,”said Chen, “Students can also make a big difference{#blank#}10{#/blank#}society.”

    The carrier rocket sent a Shenzhou-ll spacecraft（航天器）with astronauts Chen Dong and Jing  Haipeng into space. The rocket was fired from the Jiuquan Satellite Launch Center{#blank#}1{#/blank#}the Gobi desert. After two days in Earth's orbit, the spacecraft{#blank#}2{#/blank#}(be) to link up with China's space  laboratory, called the Tiankong-2,{#blank#}3{#/blank#}name means“Heavenly Palace 2". The lab {#blank#}4{#/blank#} (place) into orbit last month.

    The astronauts will spend 30 days on the Tiankong-2. They plan to perform {#blank#}5{#/blank#} (science) and spacecraft-related experiments and test systems for a future space station. In{#blank#}6{#/blank#}words, the Tiankong

    2 laboratory will not be part of that space station. Its main goal is to practice the techniques and the{#blank#}7{#/blank#}(technology) that they will be {#blank#}8{#/blank#}(use)to build and operate that final space station.

    It is predicted that the Chinese space station will be built mostly by machine. China hopes to have the space station{#blank#}9{#/blank#} (complete) by 2022 and it is expected to operate for at least 10 years.

    China also plans to land a probe（探测器）on Mars by 2020. Until now, China has completed a total of five manned space missions. And, in 2003,it {#blank#}10{#/blank#} (successful)landed a probe on the moon.

    Tea is an important part of Chinese tradition. The practice of drinking tea has{#blank#}1{#/blank#}long history in China, having originated there. Nowadays, Chinese tea generally represents tea leaves which have been processed {#blank#}2{#/blank#}(use) methods inherited from ancient China.

    According to popular legend, tea{#blank#}3{#/blank#}(discover) by Chinese Emperor Shen Nong in 2737 BC{#blank#}4{#/blank#}a leaf from a nearby shrub fell into the water the emperor was boiling. The Emperor was interested in the new liquid,{#blank#}5{#/blank#} (drink) some carefully, and found it very refreshing. And so, tea was said to be created in 2737 BC.

    Tea is deeply woven into the history and culture of China. The beverage(饮料) is considered one of the seven{#blank#}6{#/blank#}(necessity) of Chinese life, along with firewood, rice, oil, salt, soy sauce and vinegar. Around 771 BC—476 BC the Chinese tea was used {#blank#}7{#/blank#}(help) treat some diseases.

    Most Chinese teas are cultivated and consumed in China. Tea shops and tea houses in the street are easily found in China. Meanwhile, they are also exported internationally due{#blank#}8{#/blank#} a rise in the{#blank#}9{#/blank#}(popular) of Chinese cuisine worldwide. Tea has become one of Chinese specific drinks in the world. It is {#blank#}10{#/blank#}(common) available in Chinese restaurants and grocery shops world wide.

    If you study abroad, it's necessary to mix with the locals. This allows you{#blank#}1{#/blank#}(test) your language skills and find out more about the local culture. Having lived abroad for three years, I'm able to put forward a list of tips to help you make friends in a foreign country.

    Firstly, say yes to everything within reason. Obviously, if you don't feel {#blank#}2{#/blank#} ease, you can choose not to do anything. However, don't put off trying something new. The group of students from your class who invite you out for a coffee might end up {#blank#}3{#/blank#}(be) your friends for life!

    Secondly, develop a {#blank#}4{#/blank#} (entire) new hobby. Join a dance class, a walking club or learn to cook the local food—the {#blank#}5{#/blank#}(possibility) are endless!

    Thirdly, get out of the house! Hours {#blank#}6{#/blank#}(spend) on the computer chatting with your family back at home surely make you even homesick. Just get out and explore the exciting place you live in.

    Lastly, be {#blank#}7{#/blank#}(confidence) when you are surrounded by people speaking {#blank#}8{#/blank#} unfamiliar language. Even if you may find {#blank#}9{#/blank#} difficult to involve yourself in conversations, you should try to make your voice heard. Once you open your mouth and begin to speak, it's likely {#blank#}10{#/blank#} you will find everyone wants to know more about you.

    The Hong Kong –Zhuhai–Macao Bridge, the world's {#blank#}1{#/blank#} (long) cross-sea bridge, enters the history of human engineering and connection as a point of pride upon {#blank#}2{#/blank#} (it) opening to traffic at 9 a. m. on Oct. 24, 2018.

    One day after the opening was announced at a ceremony {#blank#}3{#/blank#} (hold) in Zhuhai, the bridge's ports in three different administrative regions started serving travelers around the clock, opening 24 hours a day, seven days a week. {#blank#}4{#/blank#} (ensure) faster boundary crossings for passengers, the Macao and Zhuhai ports jointly use a one-off immigration model, {#blank#}5{#/blank#} allows travelers to queue up only once to finish both exit and entry procedures of the two cities in about thirty {#blank#}6{#/blank#} (second).

    Apart {#blank#}7{#/blank#} private cars, taxis and goods vehicles, two types of public transportation—shuttle bus and cross-boundary coach—can also run on the HZMB. {#blank#}8{#/blank#} frequency of shuttle buses is about 5-10 minutes during peak hours. Booking tickets for the shuttle bus online in advance {#blank#}9{#/blank#} (be) available since 9 am on Tuesday. With the bridge now in service, the travelling time between Zhuhai and Hong Kong International Airport will {#blank#}10{#/blank#} (shorten) from 4 hours to 45 minutes.

    {#blank#}1{#/blank#}(see) from outer space, Earth is a blue planet, due to the fact that the ocean covers over 70 percent of its surface. According to a new study published in the journal Science, the ocean plays a great role in {#blank#}2{#/blank#}(slow)down global warming. It is" {#blank#}3{#/blank#}important buffer(缓冲物)", {#blank#}4{#/blank#}The New York Times put it.

    The oceans can absorb 93 percent of the heat trapped by the greenhouse gases {#blank#}5{#/blank#}humans release into the atmosphere. And the other 7 percent {#blank#}6{#/blank#}(absorb)by the air, land and ice caps, according to the Guardian.

    "If the ocean wasn't absorbing as much heat, the surface of the land would heat up much {#blank#}7{#/blank#} (fast) than it is right now," said professor Malin L. Pinsky at Rutgers University in the US. "In fact, the ocean is saving us from rapid warming right now."

    However, the ocean itself, as Discover Magazine noted, is heating up 40 percent faster on average than the United Nations {#blank#}8{#/blank#}(believe) five years ago. That means if the ocean temperatures increase {#blank#}9{#/blank#} this speed, the high water temperatures "will kill off marine ecosystems, raise sea {#blank#}10{#/blank#} (level) and make hurricanes more destructive (破坏性的)", the Guardian reported.
