“Our aim is to take our art to the world and make people understand what it is to move,” said David Belle, the founder of parkour(跑酷).

Do you love running? It is a good exercise, yet many people find it boring. But what if making your morning jog a creative one? Like jumping from walls and over gaps, and ground rolls? Just like the James Bond in the movie Casino Royale? Bond jumps down from a roof to a windowsill and then runs several blocks over obstacles on the way. It is just because of Bond’s wonderful performances that the sport has become popular worldwide.

Yes, that’s parkour, an extreme street sport aimed at moving from one point to another as quickly as possible, getting over all the obstacles in the path using only the abilities of the human body. Parkour is considered an extreme sport. As its participants dash around a city, they may jump over fences, run up walls and even move from rooftop to rooftop.

Parkour can be just as exciting and charming as it sounds, but its participants see parkour much more than that.

Overcoming all the obstacles on the course and in life is part of the philosophy(理念) behind parkour. This is the same as life. You must determine your destination, go straight, jump over all the barriers as if in parkour and never fall back from them in your life, to reach the destination successfully. A parkour lover said, “I love parkour because its philosophy has become my life, my way to do everything.”

Another philosophy we’ve learnt from parkour is freedom. It can be done by anyone, at any time, anywhere in the world. It is a kind of expression of trust in yourself that you earn energy and confidence.

Parkour has become popular throughout the world because of     .

A. its founder, David Belle                  B. the film, Casino Royale

C. its risks and tricks                          D. the varieties of participants

The underlined word “obstacles” in Paragraph 2 is closest in meaning to “    ”.

A. streets                                           B. objects

C. barriers                                         D. roofs

Which of the following is true of parkour?

A. It challenges human abilities.          B. It is a good but boring sport.

C. It needs special training.                 D. It is a team sport.

As its participants move around a city,     .

A. they can ask for help                      B. they may choose to escape

C. they should run to extremes             D. they must learn to survive

Which of the following is the philosophy of parkour?

A. Sports and extremes.                      B. Excitement and popularity.

C. Dreams and success.                       D. Determination and freedom.

科目:高中英語 來源:2015屆四川省高一12月檢測英語試卷(解析版) 題型:閱讀理解

Food sometimes gets poisoned with harmful things. A person who eats such food can get an illness called food poisoning(中毒). Food poisoning is usually not serious, but some types are deadly. The symptoms of food poisoning usually begin within hours of eating the poisoned food. Fever is one of the most common symptoms.

Certain microorganisms(微生物)cause most types of food poisoning. Bacteria and other microorganisms can poison eggs, meat, vegetables, and many other foods. After entering the body, these tiny living things release(釋放)poisons that make people sick.

Some chemicals can also cause food poisoning. They are often added to food while it is being grown, processed, or prepared. For example, many farmers spray chemicals on crops to kill weeds and insects. Some people may have a bad reaction to those chemicals when they eat the crops.

Some plants and animals contain natural poisons that are harmful to people. These include certain kinds of seafood, grains, nuts, seeds, beans, and mushrooms.

When people handle food properly, the risk of food poisoning is very small. Microorganisms multiply rapidly in dirty places and in warm temperatures. This means that people should never touch food with dirty hands or put food on unwashed surfaces. Food should be kept in a refrigerator to stop microorganisms from growing. Meat needs to be cooked thoroughly to kill any dangerous microorganisms. People should also wash food covered with chemicals before eating it. Finally, people should not eat wild mushrooms or other foods that grow in the wild. Some of these foods may contain natural materials that are poisonous to humans. In addition, some types of fish can be poisonous.

Most people recover from food poisoning after a few days of resting and drinking extra water. If people eat natural poisons, they must go to the hospital right away to have their stomachs emptied.

1.Which of the following statements is NOT true?

A.Food when poisoned can make people sick.   B.Food poisoning means death.

A.are always accompanied by a fever          B.are too common to be noted

C.can be noticed within hours               D.can he ignored

3.Food poisoning can be caused by all the following EXCEPT       .

A.some chemicals                        B.low temperatures

C.some tiny living things                    D.certain natural materials

4.From Paragraph 5,we can learn that        .

A.mushrooms should not be eaten

B.vegetables are safer than meat and seafood

C.natural poisons are more dangerous than chemicals

D.different types of food should be handled differently

5.It can be inferred from the passage that       .
