A recent study led by researchers from the National University of Singapore (NUS) has found a clear link between the color of a taxi and its accident rate. An analysis of 36 months of detailed taxi, driver and accident data from two fleets of yellow and blue taxis in Singapore suggested that yellow taxis have fewer accidents than blue taxis. The higher visibility (能見度） of yellow makes it less difficult for drivers to avoid getting into accidents with yellow taxis, leading to a lower accident rate.

The study was led by Prof Ho. To test whether there was a relationship between the color of a taxi and the number of accidents the taxi had, the research team analysed data collected by the largest taxi company in Singapore. The researchers found that yellow taxis have about 6. 1 fewer accidents per 1,000 taxis per month.

They also studied the economic effect of changing the color of the entire fleet of taxis to yellow. The Singapore taxi company involved in the study owns about 16,700 taxis in a ratio (比例) of one yellow to three blue taxis. If a commercial decision is made to switch from blue to yellow taxis, 76. 6 fewer accidents will occur per month or 917 fewer accidents per year.

Assuming an average repair cost of $1,000 per car and a downtime of six days, the color of all taxis to yellow could produce an annual saving of $2 million.

“We are eager to continue to validate (證實) the findings of our study by looking at the use of yellow in other types of public transport, such as school buses. For example, we hope to compare the accident rates of yellow school buses against those of other colors to find out if yellow is indeed a safer color for school buses. Besides, we’ re also interested to look at private-hire vehicles and do a comparison of the accident rates of vehicles that are of different colors explained Prof Ho.

1.Why do yellow taxis result in fewer accidents?

A. Because yellow signals a warning of danger.

B. Because yellow can be seen more easily.

C. Because drivers tend to he more careful in yellow taxis.

D. Because people act more quickly in yellow surroundings.

2.What’ s Prof Ho’s study based on?

A. Physical risks taxi passengers experience.

B. The economic effect of changing taxi color.

C. Personal reports from taxi drivers worldwide.

D. Data from Singapore's largest taxi company.

3.What do Prof Ho’s words in the last paragraph suggest?

A. School buses should be painted yellow.

B. Their findings are worth popularizing.

C. Their study will be furthered.

D. Yellow should be widely used in public transport,

4.What can be the best title for the text?

A. Safer to ride in yellow taxis B. Caution: yellow taxis ahead

C. Why are yellow Taxis preferred? D. How can colors help prevent accidents?

Four Wild Animal Species Were Endangered

Maybe you can still see them at the zoo. But that doesn’t mean they’re doing alright in the wild.

Tigers

All six tiger species are endangered, with Sumatran tigers and South Chin tigers at a seriously endangered status. The main reasons for their population decline are illegal hunting and destroyed habitats(棲息地), as humans clear forests to gather timber（木材）and build roadways. Only about 3890 tigers presently live in the wild.

Ground squirrels

That’s right, even squirrels are endangered, specifically the San Joaquin ground squirrel. Native to California, USA, these guys have been disappearing since 1979 on account of the construction and human developments going through their habitat. Their total population is unknown , but it could be anywhere between 124000 and 413000.

Giraffes

The International Union for the Conservation of Nature recently put giraffes at a vulnerable status, the level just before endangered. The giraffe population has declined 40 percent in the last 30 years, primarily due to loss of habitat and illegal hunting. Some giraffes are killed just for their tails, which are considered status symbols in Africa.

Asian elephants

The main threat to Asian elephants, one of the most intelligent animals, is their shrinking habitat. As the human population grows, people invade their land to build roads and railway tracks. Elephants in Myanmar are at an especially high risk for being captured and traded or used illegally in the tourist industry. Fewer than 50000 are left on the entire continent.

1.What is the total population of tigers living in the wild?

A. Around 3890.

B. 50000.

C. 124000.

D. 413000.

2.Which of the following is considered one of the most intelligent animals?

A. Tigers.

B. Giraffes.

C. Ground squirrels.

D. Asian elephants.

3.What is the common threat to the four wild animals?

A. Illegal hunting.

B. Disturbed habitat.

C. Developing tourism.

D. Unnecessary construction.

4.Which word can best describe the present situation for protecting wild animals?

A. Satisfactory.

B. Optimistic.

C. Urgent.

D. Stable.

One day on my way to school, I went to buy the pancake in a food store, leave my bag on the table while waiting. With the pancake ready, and I paid for it, took “my bag” on the table, and hurriedly headed to school.

Seating in the classroom, I was about to take my books out while suddenly I became frozen. It was not my bag! I took the bag for mistake! What surprised me most was there was a large sum of money in it. Calming me down, I turned to the teacher for help.

At that time, I come to understand the true meaning of being honestly.
