The Peppered Moth, a kind of insect, is found in England. It is light brown in color and likes to settle on trees which are also light brown. This makes the moth difficult to be seen and birds are less likely to notice and eat it.
But with the development of industry, smoke from factories began to reach the trees where the moth settled. It made the trees blacker. Then something very strange took place: in industrial areas, the Peppered Moth began to change color. It became darker as well. Although the change took several years, some scientists soon noticed that newly-born moths were a little darker than usual.
A scientist called Kettle Well decided to make a careful study of this. He marked some of the light moths and some of the darker ones, and set them free in the woods near Birmingham, an industrial city. Later he retarget as many the marked moths as possible ( The result was given in the chart ).
Kettle Well’s research was done in the early 1950s. Soon afterwards Britain introduced new laws to reduce smoke and factory pollution.

Across the globe, single-parent homes are on the rise. In the US, the 2000 census (人口普查 ) showed 24.8 million or nearly 24 percent of the nation's 105.5 million households, were traditional two-parent homes. By comparison, 9.8 million households or 9.8 million of all US households were headed by an adult raising a child alone. The 1990 census showed 26 percent of homes were led by a married mother and father, and 8 percent of homes were led by a singe parent.
Similar increases occurred in other countries. In the UK, lone-parent family homes increased from 3.3 percent in 1990 to 5.5 percent in 1999. Single parent households in Australia rose from 5.8 percent in 1990 to 7.6 percent in l999. Belgium saw the increase from 1. 8 percent to 2.7 during the same period of time. These countries tend to have greater acceptance of single parenting because there are fewer nearby family members to disapprove, Riche, a Census Bureau director, said.
Just as in the US, those changes raised new questions about how involved government should be in helping single-parent families. Some research suggests children raised in two-parent families are better off than those who depend on one.
"The position of one-parent families in any country is very much a gender (性别) issue－women's opportunities, especially working-class women on low income," said Sue Chen, coordinator (协调员) of the Single Action Parents Network in England.Not considering the exact number of the single-parent families, which country saw the fastest rise rate in 1999, compared with 1990?
| A．UK. | B．Australia. | C．America. | D．Belgium. |
What is the cause of the rise of single-parent families across the globe?
| A．The nearby family members have a favorable opinion. |
| B．A lone parent is well off enough to support his/her children. |
| C．A lot of problems have arisen in two-parent families. |
| D．We cannot get enough proving information from the text. |
Which of the following is TRUE about the increase of single-parent families according to the passage?
A. It will somewhat limit the growing population of younger generation.
B. Governments should take actions about the social problems brought about by it.
C. Single-parent families are not looked down upon in any country mentioned here.
How can you help kids cope with （对付）stress? Proper rest and good nutrition can improve coping skills, so can good parenting. Make time for your kids each day. Whether they need to talk with you or just be in the same room with you, make yourself available.
Even as kids get older, quality time is important. It’s really hard for some people to come home after a tiring day of work, get down on the floor, and play with their kids or just talk to them about their day -- especially if they’ve had a stressful day themselves. But expressing interest in your kids shows that they’ re important to you.
Help your child deal with stress by talking about what may be causing it. Together, you can come up with a few solutions. For example, he should cut back on after-school activities, spending more time talking with his parents or teachers, developing an exercise plan or keeping a journal.
You can also help by predicting potentially stressful situations and preparing kids for them. For example, let a child know ahead of time, but not too far ahead of time, that a doctor’s appointment is coming up and talk about what will happen there. Keep in mind, though, that younger kids probably won’t need too much advance preparation. Too much information can cause more stress.
Remember that some level of stress is normal, Let kids know that it’s OK to feel angry, scared, lonely, or anxious and that other people share those feelings, too.
When kids can’t or won’t discuss these problems, try talking about your own concerns. This shows that you’re willing to handle tough topics and are available to talk with when they’re ready. If a child shows symptoms that concern you and is unwilling to talk, consult a counselor （顾问）or other mental health experts.

My grandfather came from Hungary and was the only one in his family who settled down in the United States. The rest of his family remained in Europe. When World War I broke out, he seemed to have become another man, downhearted. Such obvious change was not born out of concern for his welfare, but out of fear: if his only son, my uncle, had to go to war, it would be cousin fighting against cousin.
One day in 1918, my Uncle Milton received his draft notice. My grandparents were very upset. But my mother, at the age of 10, felt on top of the world about her soldier brother going off to war. Realizing how he was regarded by his little sister and all of her friends, my uncle bought them all service pins, which meant that they had a loved one in the service. All the little girls were delighted.
The moment came when my uncle and the other soldiers, without any training but all in uniforms, boarded the train. The band played and the crowd cheered. Although no one noticed. I’m sure my grandmother had a tear in her eye for the only son. The train slowly pulled out, but not about a thousand yards when it suddenly paused. Everyone stared in wonder as the train slowly returned to the station. There was a dead silence before the doors opened and the men started to step out. Someone shouted, “The war is over!” For a moment, nobody moved, but then the people heard someone bark orders at the soldiers. The men lined up in two lines, walked down the steps, and with the band playing, marched down the street, as returning heroes, to be welcomed home. My mother said it was a great day, but she was just a little disappointed that it didn’t last a tiny bit longer.What the grandfather was most worried about was ______.

false ideas about being fat and doing weight as they get older, while others
I‘ll never lose weight一I come from a fat family
Wrong! While we can’t change the body type we are bom with, we can’t blame our genes for making us fat. There’s plenty of evidence that fatness runs in families, and the main reason is that they

The Cost of Higher Education
Individuals (个人) should pay for their higher education.
A university education is of huge and direct benefit to the individual. Graduates earn more than non-graduates. Meanwhile, social mobility is ever more dependent on having a degree. However, only some people have it. So the individual, not the taxpayers, should pay for it. There are pressing calls on the resources (资源) of the government. Using taxpayers' money to help a small number of people to earn high incomes in the future is not one of them.
Full government funding (资助) is not very good for universities. Adam Smith worked in a Scottish university whose teachers lived off student fees. He knew and looked down upon 18th-century Oxford, where the academics lived comfortably off the income received from the government. Guaranteed salaries, Smith argued, were the enemy of hard work; and when the academics were lazy and incompetent, the students were similarly lazy.
If students have to pay for their education, they not only work harder, but also demand more from their teachers. And their teachers have to keep them satisfied. If that means taking teaching seriously, and giving less time to their own research interests, that is surely something to celebrate.
Many people believe that higher education should be free because it is good for the economy (经济). Many graduates clearly do contribute to national wealth, but so do all the businesses that invest (投资) and create jobs. If you believe that the government should pay for higher education because graduates are economically productive, you should also believe that the government should pay part of business costs. Anyone promising to create jobs should receive a gift of capital from the government to invest. Therefore, it is the individual, not the government, who should pay for their university education. The underlined word "them" in Paragraph 2 refers to
| A．taxpayers | B．pressing calls | C．college graduates | D．government resources |
The author thinks that with full government funding
| A．teachers are less satisfied |
| B．students are more demanding |
| C．students will become more competent |
| D．teachers will spend less time on teaching |
The author mentions businesses in Paragraph 5 in order to
| A．argue against free university education |
| B．call on them to finance students' studies |
| C．encourage graduates to go into business |
| D．show their contribution to higher education |
