A planet the size of Jupiter has been discovered and it is one of the hottest ones known to us. This has made scientists think about how planets are formed.
Planets such as Earth have more oxygen than carbon, but what if the composition（组成）is just the opposite? This is a question opened up by a recent discovery of a diamond planet by US and UK scientists. The planet is 1200 light years away from Earth and was observed using NASA's Spitzer Space Telescope. Dr Marek Kukula explained that researchers initially used the Super WASP(Wide Angle Search for Planets) robotic observatories operating continuously, all year around. They detected the planet, then it was observed with the Spitzer Space Telescope, which detected the heat coming from the planet, and from that heat signature they can tell what this planet is made from.
The planet is very different to Earth. "It's giant planet," explains Dr Kukula, "a gas planet, a bit like Jupiter in our solar system. But the interesting thing that they've discovered is that it has a very different composition to the planets in our solar system. This planet has more carbon than oxygen." This suggests that there is more than one way to make a solar system and the range of planets in the universe could be much wider than previously thought.
Dr Kukula says that if there are smaller planets in the same solar system with a similar composition, rich in carbon, their rocks could be rich in minerals such as carbon and diamonds, unlike Earth which has silica（硅石）, the sand that rocks on Earth are made from. "This is where this diamond planet idea comes from; they haven't actually detected a diamond planet yet," explains Dr Kukula.it' s hypothetical（假设的）, "but you can imagine strange landscapes with black graphite rocks lying around and the surface could be covered with sticky liquids instead of water".
1.What planet has been discovered recently?
A.A planet with more oxygen. B.A planet with more carbon
C.A planet hotter than others. D.A planet bigger than Jupiter.
2.How do scientists decide a planet's composition?
A.By its heat. B.By its size.
C.By telescope. D.By distance.
3.What can we learn about the new planet from paragraph 3?
A.It is in our solar system. B.It looks like Earth.
C.It is completely different from Jupiter. D.It contains a lot of gas.
4.Why do scientists call the planet "a diamond planet"?
A.It is rich in carbon. B.It is rich in silica.
C.It is rich in water. D.It is rich in sticky liquids.

阅读下面材料，在空白处填入适当的内容（1个单词）或括号内单词的正确形式。
As is known to us, the year 2016 has one extra day in it — February 29th. This is because it’s 1. we call “a leap year”. Every four years, the year has 366 days in 2. instead of 365.
It is called a leap year because hundreds of years ago in England, the extra day wasn’t 3. (legal) recognized. There is a well-known tradition in the UK 4. (associate) with February 29th, introduced many centuries ago. Women are allowed to break with tradition and propose(求婚) to their boyfriends on this day. This all started back in the 5. (five) century, when a famous Irish saint made a 6. (complain) that women had to wait too long for men to propose. According to the legend, Saint Patrick said any female dreaming of a proposal could ask her boyfriend to marry her on this additional day in February. This so-called tradition 7. (write) in law in the thirteenth century. Scotland passed a law allowing women to propose to men in a leap year. It was said that if the men refused, they had to pay a fine!
Now in 2016, there are calls 8. February 29th to become a public holiday. Some people believe that it should be an 9. (office) day off, because no one gets 10. (many) payments for working an extra day in a leap year. For the moment though, the British still have to go to work on this day.

At the age of seven, I went to see my grandma in Warwick and spent the summer with her. One day I went to a general store with a 34full of what Grandma needed.
“Excuse me, I need to 35 these,” I said .
“So ? I’m not your 36! You should get yourself a basket and start filling,” Miss Bee, the owner of the store, said 37 without smiling. “If you’re 38 you’ll be home by sunset.” Sunset was five hours away. 39, the store was a puzzle, and I wasn’t sure if I would make it.

Glad I met Miss Bee ? No!
Until one day my daughter came to me with homework47. “It’s too hard,” she said. “Could you finish it for me?”
