China plans to launch 156 small satellites by 2025 toprovide Internet services in low signal areas and placeswith adverse natural environment, according toChinaAerospace Science and Industry Corporation(CASIC).
Due to environmental conditionsof deserts,mountains and seas, half of the world's population has noaccess to the Internet, and the information deficiencyhamperslocal development.
It will be China's first broadband Internet accesssystem with small satellites hovering in low orbit, whichwill also help meet the needs of commercial space development.
The project, named Hongyun, plans to send the firstsatellite by 2019, and launch four more by 2020. By theend of 2025, CASIC plans to have all of the 156 satellites in operation.
The Hongyun Proiect, which focuses on communication,remote sensing and navigation, can offer communicationand Internet services for China and less-developed 3countries with reduced latency. Meanwhile, the projectcan also benefit emergency communication, sensor data collection and remote control of unmanned equipment.
Currently, international maritime satellites are widely used in communications in mountainous areas and airplanes, but those satellites, 36, 000 kilometers abovethe Earth, have time and signal delay as well as high cost for providing services.
The small satellites sent by the Hongyun Project will hover in low orbits only hundreds of kilometers to 1, 000 kilometers above the Earth, and thus could improve the Internet access. However, the low orbit satellites may face challenges in power supply, as they need more energyto reduce the influence of air-resistance compared to highorbit satellites. Experiments are needed to determinewhether solar energy alone is enough.
1.According to the passage, ________________.
A.156satellites will be launched by the Hongyun Project by 2020
B.international maritime satellites can cause signaldelay
C.The Hongyun Project may not encourage commercialspace development
D.low orbit satellites are currently used widely incommunications in mountainous areas
2.The underlined word “hampers” in Paragraph2 probably refers to ________.
A.accelerates B.determines
C.prevents D.promotes
3.Which of the following is not included in the HongyunProject?
A.Communication and Navigation. B.Remote sensing.
C.Data collection. D.Solar energy.
4.Low orbit satellites need more energy in order to________.
A.provide more accurate data B.improve the Internet access
C.reduce the effect of air-resistance D.face more challenges

China has now mapped out plans for its next four launches in the Shenzhou program on the next flight. But one conclusion seems to have escaped most reports in the aerospace media. The flight of Shenzhou 7 could be timed to coincide with the Beijing Olympics. Plans for the 2008 Summer Olympics call for the events to be held between the 8th and 24th of August. It's reasonable to expect that China will use the event to promote its achievements before the world, and human spaceflight is China's most significant recent breakthrough.
Shenzhou 7, China's next manned space mission, was originally advertised for 2007. This fit into the pattern of staging a two-year gap between crewed Shenzhou missions, which have previously launched in 2003 and 2005. But Chinese media statements have recently amended this to 2008. Chinese media have reported that while the overall program is going well, more time is needed to work on the spacesuit that will be used on this flight to stage China's first spacewalk. It's possible that Chinese engineers want to make best preparations for this complex mission.
China could intend to carry out the mission of Shenzhou 7 just as media attention is focused on the lead-up to the Olympics. The crew of the flight, and possibly China's other flown astronauts, could then take part in the opening ceremony. China has previously feted her space travellers in great celebrations, such as the Hong Kong event that saw Yang Liwei singing with actor Jacky Chan.
China has also suggested that the activity will be carried out by a single astronaut, and has indicated that half an hour is a rough estimate of the planned time for the spacewalk. China is apparently following suit, probably for the same reasons of conservative mission planning and safety.
1.From the first paragraph we can infer that ___________.
A. China hasn’t made its plan for the Beijing Olympics
B. the new Shenzhou program are known to all the reporters
C. China has planned to send up Shenzhou 7 in 2008
D. Beijing Olympics will be held during the flight of Shenzhou 7
2.China has decided to carry out its human spaceflight in 2008 in order to _________.
A. make the Beijing Olympics more interesting.
B. show its great achievements to the world.
C. prove that China is a developed country.
D. introduce its science and technology to the world.
3.Which one of the following is WRONG according to this passage?
A. China sent its first manned spacecraft in October of 2003.
B. Chinese engineers want to make more preparations for Shenzhou 7.
C. The spacesuit for the flight of Shenzhou 7 hasn’t been prepared well.
D. Two Chinese astronauts walked in space in 2003.
4.The underlined word “amended” in the passage has a similar meaning to _________.
A. improve B. change C. expect D. decide
5.What would be the best title for this passage?
A. The Beijing Olympics.
B. The Shenzhou Olympics.
C. China’s Shenzhou Program.
D. Spacewalk in 2008.

Taiwan will finalize a plan by the end of June to open up the island to tourists from mainland China, though no date has been fixed for formal implementation（执行）, an official at the Mainland Affairs Council（MAC）said on Monday．
The official said the reports in the local press on Monday that the MAC has decided to postpone its plan to announce the implementation of the new plan on July 1 were inaccurate．
The official said cooperation between different organizations was still underway．The United Daily news quoted the director of the MAC’s legal affairs department, Liu Thehsun, as saying the plan to open up to mainland tourists would not be implemented as scheduled due to a lack of cross-strait communication．
Although relevant authorities, including the Bureau of Immigration and the Tourism Bureau, have complete reports on how to deal with visitors from mainland China, the decision has been taken not to press, ahead with announcement of the plan’s implementation on the first of July, Liu was quoted as saying．
The report also said that while no restrictions would be imposed on the mainland visitors in terms of age or residence in China, the visitors would need to hold a steady job or have more than 50,000RMB（about 6,000, U．S．dollars）in bank savings before they would be eligible（有资格的）to visit Taiwan．
In addition, Taiwan bound mainland tourists would have to come as part of a tour group and would be allowed to stay a maximum of 10 days each time．
The number of mainland tourists allowed to enter the island would also initially be limited to 1,000 people a day．
Although most people from Taiwan are free to travel to China, only a small number of mainland Chinese have been able to visit the island due to restrictions imposed by both sides of the Taiwan Strait after the end of a civil war in 1949．
1.At the moment, according to the passage,___________．
A．no mainland Chinese can visit Taiwan now
B．any mainland Chinese can visit Taiwan now
C．many mainland Chinese have ever visited Taiwan since 1949

B．mainland visitors who want to travel in Taiwan must have at least ￥50,000 in the bank savings account
C．there will be no age restrictions to the mainland visitors
D．mainland visitors will be free to travel to Taiwan
3.We can infer from the passage that ______get（s）involved in the implementation of the plan．
A．MAC B．United Daily
C．several organizations D．Bureau of Immigration
4.Which of the following statement is TRUE?
A．The implementation of the plan has not been fixed．
B．It was originally fixed on July 1 to announce the plan’s implementation．
