A

Can you resist cream cakes? I miss my sugar! I’ve decided to lose weight and I had to give up cakes. It’s difficult because I have a sweet tooth and I love cream cakes.

Not having treats can be good for your health. I’ve heard that the Burts, a family of five in South East England,lived sugar free for a whole year after they found out their daughter had diabetes (糖尿 病).It wasn’t easy. To avoid temptation, I don’t go to any bakeries, but this family actually owns one, which makes up to 3 ,000 cakes a week.

They were in shock when the doctor said that their 16-year-old Lucy had to check her blood sugar levels regularly and take insulin (胰岛素). He advised her to eat a normal,balanced diet,but the Burts went further and got rid of sugar altogether.

And how does it feel to live without sugar for a while? Jason Burt said that for a month they felt weak. But later on it all changed. He says he feels “more awake” and full of energy.

And what about the Burt family business? It had to keep using half a ton of sugar a week and any cook worth his salt knows that you have to taste a recipe to know if it’s right. No problem there,says Jason Burt’s wife, Clare. She points out that she’s got lots of people offering to taste the cakes for them. The family is also thinking about selling more delicious products.

I wonder what makes us have a strong desire for sweet food. Anyway, I’ve decided to forget about the sweet taste of sugar for a while. As British model Kate Moss says:“Nothing tastes as good as skinny feels.”

21.From the passage, what do we know about the author?

A. The author runs a bakery. B. The author hates sweet taste.

C. The author is on a diet. D. The author’s daughter had diabetes.

22.What did the Burts do after hearing the doctor’s advice?

A.They were shocked. B. They went too far about it.

C.They used half a ton of sugar a week. D. They avoided sugar completely.

A.to make up to 3 ,000 cakes a week

B.to taste a recipe to know if it’s right

C.to get lots of people offering to taste the cakes

D.to selling more delicious products

24.What does the sentence by Kate Moss mean?

A.It is worthwhile to resist food to look skinny.

B.There is nothing tasting as good as sweets.

C.Nothing tastes good when the skin feels terrible.

D.Nobody can resist the desire for sweets.

B

Parents will do anything for their children. Whether it would be the food, clothes, or the place they live in,parents will always make sure their children have the best of everything. One of the big-gest concerns that parents currently have is educating their children. They are faced with lots of diffi-culties when it comes to education for their young ones. Choices include private school, charter school,public school or home schooling.

lixon 3

Fortunately for parents,there are a variety of different strategies that they can take in order to in-crease their child’s overall intelligence. According to Ross A. Thompson, PhD, professor of psychol-ogy at the University of California at Davis, a child’s brain will actually reach 90% of its full size by the time they start kindergarten.

Researchers at Northwestern University in Chicago concluded that playing a musical instrument directly affected the brain stem, the lower section of the brain. Moreover, children that learn an in-strument at an early age tend to continue it when they are older. And numerous studies show that a well balanced meal is essential for a child’s mental as well as physical health. Some other researchers recommended that a second language should be taught when children are in preschool. They state that three to four years of age is the perfect time and that any age under four would work perfectly fine for a child’s brain development.

The average child will learn how to read between kindergarten and second grade. Many parents can give their children a by teaching them to read before they start school. Children could have an adequate background of the alphabet and sounds of words before attending school. This can be done by simply reading to them whenever you want. The more comfortable they get,the easier the process will be.

A.parents find it hard to satisfy their kids’ various demands

B.parents meet a new challenge when raising their kids

C.parents have more choices in offering education to their kids

D.parents get actively involved in the process of their kids’ growth

26.What suggestion may the researchers in the passage make?

A.To train kids as early as possible.

B.To try as many means as possible.

C.To help kids develop as fully as possible.

D.To use as many available resources as possible.

27.What does the third paragraph mainly discuss about?

A.The proper time to teach children to learn languages.

B.The effective ways to help develop children’s brains.

C.The vital factors to have a great effect on children’s health.

D.The practical steps to arouse children’s interest in study.

28.We can replace the words “jump start” A.inspiration B. introduction C. suggestion D. promotion

One of the greatest gifts one generation can give to other generations is the wisdom it has gained from experience. This idea has inspired the award-winning photographer Andrew Zuckerman. He interviewed and took photos of fifty over-sixty-five-year-olds all over the world. His project explores various aspects of their lives. The photos and interviews are now available on our website.

Let us now have a culture of peace.

一Federico Mayor Zaragoza, Spain

Federico Mayor Zaragoza obtained a doctorate in pharmacy (药学)from the Complutense Uni- versity of Madrid in 1958. After many years spent in politics, he became Director-General lixon 4

of UNESCO in 1987. In 1999,he created the Foundation for a Culture of Peace, of which he is now the president. In addition to many scientific publications, he has published four collections of poems and several books of essays.

Writing is a discovery.

一Nadine Gordimer,South Africa

Due to a weak heart, Nadine Gordimer attended school and university briefly. She read widely and began writing at an early age. She published her first short story at the age of fifteen, and has completed a large number of works,which have been translated into forty languages.In 1991Gordimer won the Nobel Prize for Literature.

Jazz is about the only form of art today.

—Dave Brubeck, USA

Dave Brubeck studied music at the University of the Pacific and graduated in 1942. After World War Two he was encouraged to play jazz. In 1951,he recorded his first album (专辑).Brubeck’s 1959 album has become a jazz standard.He received a Grammy Lifetime Achievement Award in 1996.

As early as the mid-18th century, some people began raising doubts about Marco Polo’s travels. In 1995,historian Frances Wood argued in her book Did Marco Polo Go to China ? that the famous explorer from Venice never made it to pass the Black Sea. She noted that his travel journal left out the Great Wall of China,chopsticks and tea drinking among other details.Furthermore, Chinese documents from Polo’s day made no mention of the explorer and his men. Last year, a team of Italian researchers became the latest to challenge Polo’s accounts. They said that evidence didn’t support his description of Kublai Khan’s Japanese invasions (侵略).
