The Gold Coast family holidays are always great fun whether you are from Australia or from abroad. There are beautiful beaches, adventure (冒险) parks, nature parks and so much more.

There are so many sights to see here. It is a pity to drive in a car and youll miss a great part of it. Australia is home to many animals and birds that can only be seen when moving slowly and going into the areas where they live.

When you are on a bicycle, you have the advantage of being able to stop whenever you want to see an interesting animal or bird that you have never seen before. It is a quieter way of transportation as well, so you might even be able to take a picture. When you are on the beach, you can breathe that clean air and view the beauty of the water and sand. It is a totally different experience from passing it in a car.

There are many choices of hiring (租用) a bicycle to experience the Gold Coast. There are stores that will fit a bike perfectly to your size. These bikes for both adults and children are in many kinds and colors to please any taste. If you have ever wanted to try a tandem bike (双人单车), now is your chance, because they have those too.

阅读下列短文,从每题所给的四个选项 (A 、B 、C D )中,选出最佳选项。

Scientists at Harvard University have recycled a kidney(肾)-in a rat. The researchers removed a kidney from a dead rat. Later, the renewed kidney was put into a living rat. It wasn't perfect. It did, however, show signs of working like a kidney should.

"It's really beautiful work," Edward Ross, a kidney researcher at the University of Florida in Gainesville, told Science News. He didn't work on the new study.

Kidneys are bean-shaped and act like guards in the body. They clean the blood by removing waste and extra water. Every day, an adult's kidneys filter (过滤) enough blood to fill a bathtub half full. Along the way, they produce eight cups of urine (尿) from that waste and water. When a person's kidneys fail, all of that waste stays in the body. Such patients can quickly become very sick and die, unless they are regularly connected to a machine that filters their blood.

At any given time, about 100,000 people in the United States are waiting for a replacement kidney. But healthy donated kidneys are difficult to get. Either a living person must donate one, or a kidney must be removed from someone who just died and earlier had agreed to the donation. In either case, people receiving new kidneys face the r isk that their bodies will reject the donated ones.

But there may be another option. Researchers use knowledge of living things to grow or improve tissue that can aid human health. Harald Ott's team at Harvard started with a "used" kidney.

Scientists added kidney cells from rats and blood vessel cells from people to the matrix(母体). These cells attached themselves and began to multiply. Before long, they formed new kidney tissue.

The scientists placed this renewed kidney into another rat. There it produced a small amount of urine. This experiment shows that the lab-grown kidney can do at least some of the work performed by a healthy kidney.

The results are a promising first step toward helping people with serious kidney problems. "This is still very early, but they've come a long way," Ross said.

【1】What can we infer from Paragraph l?

A. Biology is a new and helpful science.

B. It's hard to put the rebuilt kidney into the rat.

C. Kidneys are very important to our life.

D. A used kidney may be recycled for new life.

【2】What does Paragraph 3 mainly talk about?

A. The relationship between kidneys and health.

B. The difficulty of curing serious kidney diseases.

C. The function and importance of kidneys.

D. The methods of curing kidneys diseases.

【3】 For what purpose does the author use the figure 100,000 in Paragraph 4?

A. To stress used kidneys are hard to get.

B. To show the great need for healthy kidneys.

C. To explain many American people get kidney diseases.

D. To call on people to donate kidneys.

【4】Which of the following is true according to the text?

A. The scientists are satisfied with the result of te experiment.

B. Ross is a kidney expert who is involved in the experiment.

C. The function of the renewed kidney is the same as a healthy kidney.

D. The renewed kidney produced a great deal of urine.

A

A big bowl of milk can be a great way to start the day. Many snack bars contain nutrients that help our bodies stay strong and healthy. But some of these foods are packed with too many vitamins and minerals. According to a new study by the Environmental Working Group (EWG), this extra fortification may be more harmful than helpful.

Of the tested snack bars, 27 have more than 50% of the recommended amounts of vitamin A, niacin and zinc. Nutrition facts listed on packages are based on recommended daily values for adults, who are physically larger and require more vitamins and minerals. So when kids eat these cereals (麦片) and snack bars, they are getting more nutrients than they need.

Vitamin A, niacin (烟酸) and zinc (锌) are best in fresh and unprocessed foods that are in their natural state. Vitamin A helps you see at night. It occurs naturally in eggs, meat and carrots. Niacin is a vitamin that helps our bodies make energy. It is found in foods like fish, seeds, and peanuts, as well as in whole grains like wheat and brown rice. Zinc helps our bodies fight off infection. It is found in many foods, including wheat-based products, meats, beans and nuts.

Children typically eat more than one serving of cereal or snack bars a day, in addition to taking vitamin supplements. Eating large amounts of these nutrients can be dangerous to kids’ health. Too much vitamin A can cause liver damage, and high levels of zinc can destroy the body’s natural immunity, or power to fight infection.

The EWG authors are calling for the FDA to make changes to its guidelines for nutrient intake and revise its daily values to match kids’ diets.

【1】 What can we infer from the second paragraph ?.

A. most kids are lack of nutrition.

B. kids need less nutrients than adults.

C. the cereals are full of all kinds of nutrients.

D. the snack bars don’t have enough nutrients .

【2】If you want to avoid infection, what food should you eat more?

A. Meat and nuts. B. Fish and rice.

C. Eggs and carrots. D. Beans and fruits.

【3】The fourth paragraph is mainly to tell us that__________.

A. children like eating fast food

B. vitamins can damage immunity

C. too many nutrients affect health

D. children should refuse to eat cereal

【4】What would be the best title for the text?

A. Nutrients and kids’ health.
