Japan is a mysterious land of technological wonders, but the latest is a relatively simple solution to an age-old problem faced by beginners and professional chefs alike.

Grocery stores across the country are about to start stocking onions that won’t make people cry. The new tear-free onion is called the Smile Ball, which is a pretty adorable name for a vegetable, and it’s an onion carefully engineered to not irritate (刺激) the eyes of people who cut into it.

Regular onions release a gas when their cells are damaged and that gas irritates people’s eyes and make them tear up. The Smile Ball onions release no such a gas, so they can be chopped easily. They are also sweet like fruit when eaten raw.

The scientific advancement of the tearless onion is not free, however. Smile Balls, developed by the Japanese producer House Foods, will cost about $4.30 for a pack of just two when they go on sale in supermarkets across Japan. That’s about double the cost of a normal onion, but it might be worth the extra money for those who are particularly sensitive to traditional onion gas. Earlier test sales of the tear-free onions were held in Tokyo, with the onions selling out quickly.

1.What do the people say about tear-free onions?

A. They’re too expensive to afford.

B. They’re sweeter than candies.

C. They're especially suitable for kids.

D. They’re worth buying, though expensive.

2.What can we learn about the Smile Ball?

A. It never gives off a strong gas.

B. It has a pretty look.

C. It belongs to a new kind of fruit.

D. It rarely goes bad.

3.What’s mainly discussed in the last paragraph?

A. How to produce tear-free onions.

B. Tearless onions are more popular.

C. The development of House Foods.

D. People are sensitive to tearless onions.

4.What can be the suitable title of the text?

A. Say Goodbye to Regular Onions

B. Tear-free Onions vs Regular Onions

C. Onions That Don’t Make You Cry

D. The Future of Tear-free Onions

The documentary “Under the Dome” went viral (走紅)online just before Chinese lawmakers opened their yearly meeting. The film examines the health effects of China’s massive air pollution, or smog problem. It also presents the difficulties environmental officials face in enforcing laws.

A former reporter for China’s state-run television, Chai Jing, produced the documentary. It argues that state-run businesses, especially energy companies, are part of China’s pollution problem.

At the end of National People’s Congress meeting, a reporter asked Prime Minister Li Keqiang whether he thought the film was correct. Are big oil companies barriers to environmental law enforcement? Mr. Li said under this year's Environmental Protection Law officials are committed to taking legal action against those who add to the pollution problem. He said anyone involved in acts of illegal production and emissions will be brought to justice. He said the government must make businesses that illegally emit(排放) and dump(丟棄) pay a price too heavy to accept.

Others also commented on the film before it was banned, including former basketball star Yao Ming. Mr. Yao served as a representative at the legislative meetings. He said he had watched the film and was thankful for the information film producer Chai Jing made public. He said the film expressed the feelings in many people’s hearts.

A respiratory(呼吸的) expert and representative at the legislative(立法的) meetings also spoke to VOA about “Under the Dome.” Zhong Nanshan said Chai Jing’s film takes a good look at where smog comes from, how harmful it is and the efforts being taken to deal with it. Previously, Mr. Zhong said that China’s smog is an even scarier problem than the serious illness SARS.

1.The documentary “Under the Dome” suggests that ______.

A. water pollution in China has very bad effect on people’s health.

B. energy companies take all the blame for China’s pollution.

C. all the state-run companies know nothing about environment protection.

D. China’s environmental departments face troubles when dealing with pollution.

2.From Para.3, we can infer that ______

A. The Chinese government will take more measures to deal with air pollution.

B. Companies must pay a lot of money before they cause some pollution.

C. Prime Minister Li praised environmental officials.

D. Prime Minister Li doesn’t think highly of the film.

3.What does the underlined phrases “be brought to justice” probably mean?

A. Be questioned B. Be removed

C. Be grounded D. Be punished

4.What is Yao Ming’s attitude to the film “Under the Dome”?

A. Indifferent B. Supportive

C. Doubtful D. Negative

科目：高中英語 來源：陜西省咸陽市2016-2017學(xué)年高二下學(xué)期第三次月考英語試卷 題型：閱讀理解

It is generally believed that we are getting cleaned when we step under a shower. We are, but we’re also giving a home to lots of tiny little creatures we didn’t even know about. A shower head carries thousands of bacteria called Mycobacterium. These can cause problems like coughs and tiredness, and a general feeling of being sick. When you turn on the water, the bacteria go from the shower head onto and into your body.

This is a finding of Norman R. Pace and his team at the University of Colorado, in the US. Pace's team looked at 45 shower heads in nine American cities. They discovered that 30 percent of them had large amounts of flying Mycobacterium.

But Pace said that they pose few threats to the health. Only those with a weak immune system might need to worry．He told the New York Times that the bacteria are not as unpleasant as might be thought. He said that having a shower is no more dangerous than anything else we do in the morning.

But for those who feel sick about the idea of all those microorganisms (微生物), he had some advice. Let the water run for 30 seconds before getting into the shower. Why? The number of bacteria is smaller than that when the water is just turned on. If that seems like a waste of water, he added that you could also change your shower head every few months.

However, Pace had good news too. He has also been testing the air in US subways. Apart from iron particles (粒子), which are ground off the track by the wheels of trains, subway air is fresh. The reason is that a train’s movement pumps fresh outdoor air into the tunnels.

1.From the finding of Norman R. Pace, after taking a shower, we might cough or feel tired because ________.

A. it’s easy to get a cold when taking a bath

B. the shower head carries many bacteria causing illness

C. we don’t get cleaned while showering

D. we don’t get a weak immune system

2.We can learn from the third paragraph that ________.

A. the bacteria always threat people’s health

B. there is no need to fear microorganisms for people with strong immune system.

C. the bacteria always threat people’s health when people have a shower

D. it is better to do some exercise in the morning than have a shower.

3.What contributes to fresh air in US subways?

A. The train’s movement. B. Iron particles.

C. Train wheels. D. Air conditioners on the trains.
