【题目】 On my fourth day in a self-driving car, I finally felt comfortable enough to let it stop itself. Before then, I'd allowed the car-a Volvo S90 sedan-to control the direction, with my hands still on the wheel, and to adjust speed in traffic. By Day 4, I was ready to make a jump into the future.

With the car traveling on a busy road, I activated the driverless mode. Soon, a traffic light turned red. For a split second, I prepared to get on the brakes. There was no need. The cameras and computers in the Volvo recognized the traffic conditions and smoothly began applying the brake.

If you're anything like most people, you're familiar with this anxiety. Almost 80 percent of Americans fear traveling in a self-driving car, a recent survey found.

Researchers at the University of Chicago have conducted some clever experiments studying the phenomenon. They asked participants to complete tasks and compare their performance with a computer system's. After the computer made a mistake, people were unwilling to use it again. After the people made mistakes, their self-confidence wouldn't change. It didn't matter that the human beings made more mistakes than the computer. So it is with driving. More than 37,000 Americans died in crashes last year, most from human error. The death count from cars goes beyond that from guns. So if you are shocked and angry by guns and want things to change, you should feel the same about car crashes.

Technology creates an opportunity to save lives. Computers don't get drunk or distracted by text messages, and they don't have blind spots. Just look at commercial airlines: Automation has helped all but get rid of deadly crashes among American air carriers. The last one happened in 2009.

The technology for self-driving cars still isn't good enough. But it is improving rapidly. Within a few years, many cars will have advanced crash-avoidance systems and driving will be revolutionized sooner than many people now understand.

2What can be learnt about the participants of the experiments?

4What does the author expect of the self-driving car?

A.I'll avoid deadly crashes entirely.B.It'll occupy the market in a short time.

C.It'll be bettered in every possible way.D.It'll be popularized sooner than expected.

【题目】 With around 100 students scheduled to be in that 9:00 am Monday morning lecture, it is no surprise that almost 20 people actually make it to the class and only 10 of them are still awake after the first 15 minutes; it is not even a surprise that most of them are still in their pajama’s(睡衣). Obviously, students are terrible at adjusting their sleep cycles to their daily schedule.

All human beings possess a body clock. Along with other alerting systems, this governs the sleep/wake cycle and is therefore one of the main processes which govern sleep behaviour. Typically, the preferred sleep/wake cycle is delayed in adolescents, which leads to many students not feeling sleepy until much later in the evenings. This typical sleep pattern is usually referred to as the “night owl” schedule of sleep.

This is opposed to the “early bird” schedule, and is a kind of disorder where the individual tends to stay up much past midnight. Such a person has great difficulty in waking up in the mornings. Research suggests that night owls feel most alert and function best in the evenings and at night. Research findings have shown that about 20 percent of people can be classified as “night owls” and only 10 percent can be classified as “early birds” ------ the other 70 percent are in the middle. Although this is clearly not true for all students, for the ones who are true night owls, this gives them an excellent excuse for missing their lectures which unfortunately fall before midday.

1What does the author stress in Paragraph 1?

A.Many students are absent from class.

B.Students are very tired on Monday mornings.

C.Students do not adjust their sleep patterns well.

D.Students are not well prepared for class on Mondays.

2Which of the following is true according to Paragraph 2?

A.Most students prefer to get up late in the morning.

B.Students don’t sleep well because of alerting systems.

C.One’s body clock governs the sleep/wake cycle independently.

D.Adolescents’ delayed sleep/wake cycle isn’t the preferred pattern.

3Which of the following is closest in meaning to the underlined word “classified”?

A.CriticizedB.GroupedC.OrganizedD.Named

4What does the text mainly talk about?

A.Functions of the body clock.

B.The “night owl” phenomenon.

C.Human beings’ sleep behaviour.

D.The school schedule of “early birds”.

【题目】 Large rainforests are extremely important ecosystems on our planet. They are home to a large number of animal and plant species, and they absorb vast amounts of carbon dioxide, which helps reduce global warming. These biggest ones in the world are a sight to observe.

Daintree Rainforest

The main river of the rainforest is the Daintree River, and it also includes the Daintree National Park. If you are wondering why everything seems to share the name, the reason is simple-Richard Daintree was a famous Australian geologist and photographer. Plenty of options will take you there, including a ferry.

Valdivian Temperate Rainforest

This rainforest is known to be extremely foggy and humid, but some interesting species live there. Since it is on the coast, you can witness ice sheets and glaciers as well. Getting to the rainforest is most accessible from Santiago, the capital of Chile, and a train ride or a bus is a preferred option.

Congo Rainforest

This rainforest also features a large number of different plant and animal species, including gorillas, forest elephants, and lions. Visiting this rainforest is also recommended by using a tour company, preferably by finding one in the Republic of Congo.

Amazon Rainforest

It is estimated that we can find 16,000 different tree species in the Amazon rainforest.

When it comes to other plants, animals, and insects, the numbers are even more impressive. The especially interesting thing is that there is still a large number of undiscovered species. A tour guide is advised since going through the rainforest can be dangerous, with predatory creatures(食肉动物)running around.

1Which of the following is named after a person?

A.Daintree Rainforest.B.The capital of Chile.

C.The Republic of Congo.D.Amazon Rainforest.

2What is recommended to visit Valdivian Temperate Rainforest?

A.By ferry.B.By train.

C.By plane.D.By bike.

3Where is this text most likely from?

A.A diary.B.A brochure.

C.A novel.D.A report.
