Many other cities in China are planning to create ______ garbage-sorting rules.
______ should we sort our garbage? The answer lies in the increasing amount of waste we are producing Chinese cities produce over 200 million tons of waste each year of and most of this waste is in landfills (垃圾填埋场), which may pollute water and soil. Besides, we are running out of ______ for new landfills.
In fact, more than half of our waste can be recycled, Recyclable garbage can be made ______ new materials, while wet garbage can be used to make gas, heat and fertilizer (肥料). But in order to recycle well, we need to sort our garbage.

You might have learned in your science classes that the sun is quite large and heavy. What if you heard that we’ve found a black hole that contains the mass (质量) of nearly 70 suns?
Chinese scientists used LAMOST, a powerful Chinese telescope (望远镜), as well as telescopes in Hawaii and the Canary Islands, to make this discovery.
According to Einstein’s theory, black holes come from dying stars. The star collapses (坍塌) into a small point with a lot of mass and strong gravity (引力). The strong gravity of the black hole allows it to pull other things in and “eat” them. Scientists search for black holes by looking at x-rays that are released when they “eat” nearby stars. However, when black holes are inactive, this method doesn’t work.
This time, the researchers looked at stars that orbit invisible (看不见的) objects. These objects, they believe, cannot be anything but black holes. After calculating (计算) the speed of one particular star in a star system named LB-1, the scientists figured out that it was orbiting (绕轨道运行) a stellar-mass black hole.
The black hole’s mass is about 70 times the mass of our sun. According to current theory, this black hole shouldn’t even be able to exist. It was previously believed that the mass of such a black hole cannot be bigger than that of 25 suns. Stellar (星球的) winds blow away the heavy elements that are left behind when a star dies. But somehow, this black hole kept most of its heavy elements.
Researchers said it is possible that the black hole formed out of two large stars that died and merged (结合) together.
The discovery is also inspiring some researchers to revisit their previous studies. “This discovery forces us to re-examine our models of how stellar-mass black holes form,” University of Florida physicist David Reitze was quoted as saying in a press release.
1.How did Chinese scientists find the stellar-mass black hole?
A.By looking at stars moving away from the black hole.
B.By studying x-rays that came from the black hole.
C.By calculating the gravity of a nearby black hole.
D.By looking at the speed of a star that orbits it.
2.What does the underlined word “inactive” mean in Chinese?
A.积极的 B.不活跃的 C.快速的 D.活泼的
3.What do we know about the black hole?
A.It is much heavier than the sun. B.It is moving faster than the sun.
C.It hasn’t “eaten” any stars. D.It will disappear soon.
4.What is the last paragraph about?
A.The importance of this discovery.
B.Previous studies on black holes.
C.The formation (形成､构成) of stellar-mass black holes.
D.The preparations that were done before making this discovery.
5.What do we know from the story?
A.Black holes are usually heavier than 25 suns.
B.We cannot believe current scientific theories.
C.Black holes can form after stars die.
D.Stellar-mass black holes contain no heavy elements.
A famous teacher was speaking to the students at our school. He began his lesson by holding up a ¥100 bill. Then he said to the three hundred students, “Who would like this ¥100 bill?” The students began to put up their hands at once.
Then he said, “I am going to give this ¥100 to one of you, but first, let me do this.” He then made the bill into a ball. Then he said, “Who wants it now?” The hands went back into the air.
“Well,” he said, “What if I do this?” and he dropped it on the floor and stepped on it. He picked up the dirty, crumpled bill and said, “Who still wants it?” Hands went back into the air.
“My friends,” he said, “you have learned a valuable lesson today. No matter (无论) what I did to the money, you still wanted it because it did not go down in value (价值). It was still worth ¥ l00!”
Many times in our lives, we are dropped, crumpled, and stepped on by the chances we take and the things that happen to us. We feel as if we are worth nothing. But remember, no matter what has happened to you, you will never lose your value: you are always valuable to those people who love you. Your value doesn’t come from what you do or whom you know, but WHO YOU ARE.
You are special and valuable. Don’t ever forget it!

In the past, working people in Britain only had holidays on “holy” (religious) days: Sundays, Christmas and Easter. Now most people have about four weeks of holiday time every year plus public (公共的) holidays (also called “bank holidays”).
When?
Most British workers take a two-week holiday in July or August. School children are on holiday from the end of July to the start of September. Taking a second holiday break in winter or spring is also becoming more popular in the UK.
Where?
The most popular holiday destinations for Brits include Spain, France, Greece and the US. Lots of people buy a package holiday that includes flights and a hotel or an apartment (公寓). Cheap overseas flights mean that many British people are able to spend two weeks a year vacationing abroad. Flights and package holidays are much cheaper during school terms and the British government is worried that some young people are skipping school (逃课) to go on holiday. Parents who take their child on vacation during term time must now pay a fine (罚款).
British people also like to go on holiday in the UK. They might go to England, Northern Ireland, Scotland or Wales, In Cornwall (康沃尔), for example, there is an environmental project called the Eden Project. You can see plants from all over the world there.
Independent (独立的) holidays
Some teenagers want to spend their holidays doing something without their family. A language exchange (交换) is one way to become more independent and improve one’s language skills. A British teenager might spend a week or two in a foreign country, staying with a family who has a son or daughter of the same age and practicing the local language. Later, the foreign teenager might visit the UK to practice their English with a British family.
