Air pollution, such as haze, has become a serious problem around the world. Besides wearing a mask, what else can we do to protect ourselves from the dirty air?

Scientists have developed a new inhaler (吸入劑) that can reduce the effect air pollution has on people. It could help millions of people who are suffering from air pollution, the Guardian reports.

This inhaler is developed by German company Bitop and contains a molecule (分子) named Ectoine. The molecule creates a layer (涂層) that protects lungs from polluted air. It’s reported that the inhaler will be affordable to most people when it comes to the market.

Air pollution kills more than three million people a year worldwide and leads to health problems like lung and heart disease and strokes, according to a 2016 research project in the journal Nature. It is also linked to brain disease, mental illness and diabetes (糖尿病).

Andreas Bilstein at Bitop believed that the inhaler could be useful around the world, because air pollution is not just a European problem: “Especially in Asia － China in particular － the demand for such a product is even higher.”

Many Chinese cities have been suffering from haze. According to World Health Organization, two of the 10 most polluted cities in the world in 2015 were in China. About 800,000 deaths that are linked to air pollution take place in the country every year.

However, such inhalers should never be an excuse for not trying to stop air pollution, said Professor Jean Krutmann at the Leibniz Research Institute for Environmental Medicine. “The best thing is that we have clean air and we don’t need any prophylactic (預(yù)防性的) treatment,” he said.

1.What is the new inhaler?

A. It can help protect the environment.

B. It can help us reduce the harm of air pollution.

C. It can solve the air pollution problem.

D. It can make the dirty air clean.

2.From the third paragraph, we learn that ________.

A. the inhaler comes from a US company

B. the inhaler is named Ectoine

C. a molecule in the inhaler forms a layer on lungs

D. the inhaler’s price will not be too high for most people

3.Which of the following is NOT true?

A. Air pollution kills millions of people a year worldwide.

B. Air pollution can cause mental illness.

C. There are no air pollution problems in Europe.

D. Air pollution is a serious problem in China.

4.Which is Professor Jean Krutmann’s opinion?

A. Such inhalers mean much to people.

B. We should take action to control air pollution.

C. We can depend on inhalers to solve air pollution problems.

D. We’d better produce more medicines to treat lung diseases.

Li Hua and Wang Hai are students of Senior One. They all work hard but have different learning methods. Li Hua listens to her teachers attentive and tries to catch everything the teachers say. She spends more time doing her homework. It is certain what she can go to bed earlier and always keeps energetic in the day.

However, Wang Hai had a different way of learning. He likes to stay up late at the night, so he often feels sleepy in class. As the result, he misses lots of key point and it usually takes him more time to finish his homework, that makes it difficult for him to concentrate what he is doing. I prefer Li Hua's learning method.

Japanese high school students either walk or ride bicycles if the distance is not too great. In other cases, students must take public buses and trains. After junior high school, students attend schools based on their high school entrance examination scores. So some students travel a great distance to attend the school.

◆________

The school day begins at 8:30. Then students assemble in their homeroom classes for the day's studies. Each homeroom has an average of 40-45 students. Students stay in their homeroom classrooms for most of the school day. Only for physical education, laboratory classes, or other subjects requiring special facilities(設(shè)備) do students move to different parts of the school. Between classes and at lunchtime, classrooms can be noisy, lively places. Some schools may have a cafeteria(自助餐廳), but most do not. In most schools, students bring a box lunch from home, prepared by the mother in the early morning hours.

Japanese students spend 240 days a year at school, 60 days more than American

students. Students in high schools take three years' studying of each of the following subjects: mathematics, social studies, Japanese, science and English. Other subjects include physical education, music, art, and moral studies(思想品德課). All the students in one grade level study the same subjects. Given the number of required subjects, electives(選修科目) are few.

◆After-school Activities

Club activities take place after school every day. Students can join only one club, and they rarely change clubs from year to year, so the clubs are relatively stable. Clubs are made up of sports clubs (baseball, soccer, judo, kendo, etc.) and culture clubs (English, broadcasting, science, etc.). New students usually are encouraged to select a club shortly after the school year begins in April. Clubs meet for two hours after school each day and many clubs continue to meet during school vacations.

1.Most Japanese high school students often have their lunch ________.

A. in restaurants

B. in school cafeterias

C. at home

D. in homeroom classrooms

2.Students in the USA go to school ________ days a year.

A. 180B. 200C. 240D. 300

3.The underlined word "rarely" in the fourth paragraph means "________".

A. alwaysB. neverC. seldomD. often

4.The best subtitle for the second and third paragraphs may be "________".

A. At schoolB. In classC. SubjectsD. Homerooms
