Children who are spanked (挨打) have lower IQs worldwide, including in the United States. All parents want smart children. Avoiding spanking and correcting misbehavior in other ways can help that happen.

A new research by Professor Murray Straus found that children in the United States who were spanked had lower IQs four years later than those who weren’t spanked. Straus and Mallie Paschall, a senior research scientist, studied nationally examples of 806 children aged 2 to 4, and 704 aged 5 to 9. Both groups were retested four years later.

The IQs of children IQs aged 2 to 4 who weren’t spanked were 5 points higher four year later than the IQs of those who were spanked. The IQs of children aged 5 to 9 who weren’t spanked were 2.8 points higher four years later than the IQs of children at the same age who were spanked. How often parents spanked made a difference. The more spanking, the slower the development of children’s mental ability. But even small amounts of spanking made a difference.

Straus also found a lower national average IQ in nations in which spanking was more popular. His analysis shows the strongest link between physical punishment and IQ is for those whose parents continue to use physical punishment even when they are teenagers.

Straus also found a lower national average IQ in nations in which spanking was more popular. His analysis shows the strongest link between physical punishment and IQ is for those whose parents continue to use physical punishment even when they are teenagers.

Straus and colleagues in 32 nations used data on physical punishment experienced by 17,404 university students when they were children. According to Straus, there’re two explanations for the relation of physical punishment to lower IQ.

First, physical punishment is extremely stressful and can become a long-lasting stressor for young children, who typically experience punishment three or more times a week. For many it continues for years. The stress of physical punishment often leads to being fearful that terrible things are about to happen and being easily shocked. They’re associated with lower IQ. Second, a higher national level of economic development leads to both fewer parents using physical punishment and a higher national IQ.

The good news is that the use of physical punishment has been decreasing worldwide, which may signal future gains in IQ across the globe. The United Nations has called on all member nations to forbid physical punishment by parents. Nevertheless, there’s evidence that attitude favoring physical punishment and actual use of physical punishment have been declining even in nations which haven’t forbidden physical punishment.

1. From the passage we can know that physical punishment will make______.

A. no scientist

B. a well-behaved child

C. a bad parent-child relationship

D. a child feel nervous continuously

2.It can be concluded from Paragraph 3 and Paragraph 4 that______.

A. long-term spanking will cause children’s mental disorder.

B. low national average IQ limits the mental development of children

C. young children have more chances to suffer from physical punishment.

D. high frequency of spanking results in slow development of children’s intelligence

3. According to Straus’s research, children’s being spanked is probably related to parents’______.

A. low income

B. little education

C. long-lasting pressure

D. passive personalities

4. It can be inferred from the last paragraph that______.

A. the improvement of global average IQ is out of the question

B. physical punishment becomes less popular in the world

C. most countries have realized the negative consequence of punishing in its member nations.

D. the UN has succeeded in banning physical punishment in its member nations

Just as the world’s most respected scientific bodies have confirmed that the world is getting hotter, they have also stated that there is strong evidence that humans are driving the warming. Countless recent reports from the world’s leading scientific bodies have said the same thing. For example, a 2010 summary of climate science by the Royal Society stated that: “There is strong evidence that the warming of the Earth over the last half-century has been caused largely by human activity.”

The idea that humans could change the planet’s climate may be counter-intuitive (与直觉不符的), but the basic science is well understood. Each year, human activity causes billions of tons of greenhouse gases to be released (释放) into the atmosphere. As scientists have known for years, these gases hold heat that would otherwise escape to space, wrapping the planet in an invisible blanket.

Of course, the planet’s climate has always been changing thanks to “natural” factors such as changes in solar or volcanic activity, or cycles relating the Earth’s going around the sun. According to the scientific literature, however, the warming recorded to date matches the pattern of warming we would expect from a build-up of greenhouse gas in the atmosphere – not the warming we would expect from other possible causes.

Even if scientists did discover another reasonable explanation for the warming observed so far, that would beg a difficult question. As Robert Henson puts it in The Rough Guide to Climate Change: “If some newly discovered factor can account for the climate change, then why can’t carbon dioxide and the other greenhouse gases?

The only way to prove with 100% certainty that humans are responsible for global warming would be to run an experiment with two identical Earths – one with human influence and one without. That obviously isn’t possible, and so most scientists are careful not to state human influence as an absolute certainty.

1.In most scientists’ opinion, the global warming is mainly caused by ____

A. solar activity

B. volcanic activity

C. the Earth’s going around the sun

D. human activity

2.The text is developed by ____

A. giving typical examples

B. following the order of space

C. analyzing a theory and arguing it

D. comparing and finding differences

3.The underline word “identical” means ____

A. totally different B. exactly the same

C. extremely important D. relatively independent

People in the United States honor their parents with two special days:Mother’s Day, on the second Sunday in May, and Father’s Day, on the third Sunday in June. These days are set aside to show love and respect for parents. They raise their children and educate them to be responsible (有责任感的) citizens. They give love and care. These two days make us think about the changing roles of mothers and fathers. More mothers now work outside the home. More fathers must help with child care.

These two special days are celebrated in many different ways. On Mother’s Day people wear carnations. A red one symbolizes a living mother. A white one shows that the mother is dead. Many people attend religious services to honor parents. It is also a day when people whose parents are dead visit the cemetery (墓地).On these days families get together at home, as well as in restaurants. They often have outdoor barbecues for Father’s Day. These are days of fun and good feelings and memories.

Another tradition is to give cards and gifts. Children make them in school. Many people make their own presents. These are valued more than the ones bought in stores. It is not the value of the gift that is important, but it is “the thought that counts”. Greeting card stores, florists, candy makers, bakeries, telephone companies, and other stores do a lot of business during these holidays.

1.Which of the following is NOT a reason for children to show love and respect for parents?

A. Parents bring up children.

B. Parents give love and care to children.

C. Parents educate children to be good persons.

D. Parents pass away before children grow up.

2.What do you think “florists” do?

A. They sell flowers.

B. They make and sell bread.

C. They offer enough room for having family parties.

D. They sell special gifts for Mother’s Day and Father’s Day.

3.What do you know from the passage?

A. Mother’s Day and Father’s Day are both in May.

B. Fewer women worked outside the home in the past.

C. Not all the children respect their parents

D. Fathers are not as important as mothers at home.

4.On Mother’s Day and Father’s Day, ________.

A. people usually have family parties

B. everyone goes to visit the cemetery

C. children always go to parents’ home

D. hand-made cards are the most valuable gifts

Football T-shirts are more commonly connected with boys than girls. This can often cause a problem when you want to find a cool shirt for a girl. That is not to say that there are no cool shirts out there for girls to wear. The problem is that they are often harder to find than the ones for boys.

You can get custom (订制的) shirt printed for girls from a number of custom print stores. Of course you have to make sure that they are legally allowed to use the logos (商标) and colours of the team you want to support.

You can also go through official channels to get the shirt you want. The official channels will generally be the large sportswear stores or the official stores of the teams. These stores will be able to use the colours of the teams and even put the name of the person who the shirt is for on it.

If you do not feel like you have to try the T-shirts on, then an online store may be your best choice. The reason for this is that you can visit various stores and find the best ones.

If you want to see what the T-shirt looks like in real life, then going to a store is the best choice. Large sportswear stores often have football shirts. These are the best places to go if you do not live close to an official store. And these stores usually have lower prices than the official stores.
