Only discovered in 1930 because of its vast distance from Earth, Pluto has remained a largely mysterious object ever since.
Some three billion miles from the Sun, Pluto, a dwarf planet, remains to be visited by a spacecraft.
Its first known satellite is called Charon . With a diameter of 1,200 km , it is half that of Pluto-unusually large for a moon in relation to its primary .
But now , using images from the Hubble Space Telescope , scientists from Johns Hopkins University , Southwest Research Institute and the Massachusetts
Both are traveling outside the orbit of Charon and are tiny by comparison , the scientists wrote in the journal Nature .
P1, the more distant of the two from Pluto , has a diameter of between 60 and 165 km while P2 is 20 percent smaller .
“Although definitive orbits cannot be obtained , both new satellites appear to be moving in circular orbits in the same orbital plane as Charon with orbital periods of about 38 days for P1 and 25 days for P2,” they wrote .
The discovery of the two new members of P1uto’s family makes it the only object in the Kuiper belt―a vast region of rock and ice beyond Neptune which contains debris from the formation of the solar system―known to have multiple satellites , the scientists said .
72．It is implied in the passage that .
A．Charon was not discovered until the late 1960s .
B．Charon is the largest satellite in the solar system
C．a(chǎn)ll the inner planets are better observed than Pluto
D．Pluto may have some more moons to be discovered
73．The underlined word “primary” in Paragraph 4 refers to .
A．size B．shape C．planet D．Earth
74．Which of the following show the possible orbits and positions of Pluto’s satellites ?
|
75．Which of the following is the best title for the passage ?
A．Pluto : furthest in the solar system . B．Pluto : two additional moons found .
C．Pluto : tiny , distant and frozen planet . D．Pluto : two satellites formed in 30 years .

B
You are standing under the most famous neon lights in the centre of London, waiting to cross the road. Suddenly the traffic stops. You hear the distant sounds of cheering, clapping and shouting. Then, like a multi-colored train, 2, 000 people with wheels on their feet zoom past you. You have just witnessed the London Skate, a twice weekly roller-skate(溜旱冰) event that attracts people in their hundreds and thou-
sands London. Skate is a completely free tour of the streets of London -the only condition is that you go along on roller-skates. It lasts between two and three hours and by the end of it you have skated between 10 and 12 miles. The skate snakes round the streets of London along several different routes. Many of the routes pass by tourist attractions such as Buckingham Palace and Big Ben. Marshals (交通協(xié)調(diào)員) go ahe- of the group, stopping the traffic so that people can skate as safely as possible. Everyone is welcome to take part and people from the age of 4 to 63 years old join the fun. "I love it very much, it is amazing. It feels just like a carnival (狂歡節(jié))，" said Celeste Beverage regular skater.
Roller-skating is really taking off across Europe and America. It is a very good way to keep fit and can be practised anywhere there is a smooth surface. Many big cities in Western Europe and in the US now ha- ve a regular group skating event. The biggest skates take place in Paris and Munich and tens of thousands of fans show up on warm evenings. "Roller-skating is taking over the world," said Julian Grenoble, a 25- year-old ski shop employee from London. Grenoble went to the Paris-Roller (Paris skate) regularly until he moved to Britain.
"It's so exciting to skate in Paris. Everyone skates so fast and puts in their best efforts!" he said. The Paris Roller is well known because of the huge attendance, the presence of marshals and the police protection. Paris is a great city for roller-skating because of its long wide streets and smooth surfaces. Roller-skating is also becoming more popular in China among young people and children. Skating fans' favorite places to practise in China are big squares.
