【題目】閱讀理解

China's introduction of the two-child policy has caused worry that the change will further make the shortage of pediatricians (兒科醫(yī)生) worse.
The number of pediatricians in China dropped from 105,000 to around 100,000 within five years, according to China's public health statistical (統(tǒng)計的) yearbook in 2015. On average, there are only 43 doctors per 100,000 children.
Wang Baoxi, a pediatrician with the Shaanxi branch of Chinese Medical Doctor Association, told Xinhua that situation was even worse in smaller cities and counties. In Weinan City, which is about 70 kilometers away from Shaanxi's capital Xi’an, they only had 17 doctors to care for 100,000 children.
The Lingnan branch of No.3 Hospital Affiliated (附屬的) with Sun Yat-sen University posted a notice telling people emergency treatment services in the pediatric department were canceled due to lack of doctors. "Since the department was finished in 2011, we have employed eight doctors. Four left in the following years,” said Shan Yutao, who works in the hospital's medical management office.
The shortage of pediatricians has made it difficult for parents. Low salary, high pressure and high risk are the main causes behind people's reluctance (不情愿) to become pediatricians.
According to the National Health and Family Planning Commission, 90 million Chinese women are allowed to have a second child under the two-child policy, which took effect on Jan. 1, 2016.
An Haiyan, an official with the Shaanxi provincial health and family planning commission, suggested that more attention be paid to pediatric departments in hospitals, and pediatricians be given subsidy (補貼) for their work.
（1）What is people's idea towards the two-child policy according to Paragraph One?
A.Supportive.
B.Against.
C.Unconcerned.
D.Worried.
（2）Why don't people want to become pediatricians?
① Because pediatricians have low salary.
② Because pediatricians have high risk.
③ Because pediatricians' work is hard.
④ Because pediatricians have high pressure.
A.①②④
B.①②③
C.②③④
D.①②③④
（3）What do the underlined words “due to” mean in Paragraph Four?
A.Unaware of.
B.As a result of.
C.Even though.
D.Afraid of.
（4）What is the main idea of the passage?
A.The two-child policy was coming.
B.More pediatricians are needed.
C.Some parents are worried about their second child.
D.Some hospitals can provide good service for children.

【題目】 People have seen the colorful shared bikes (共享單車) in the city streets around China for two years. People can rent (租用) them with a smart phone app and then park anywhere they choose. To relieve (減少) traffic jams and air pollution, many cities have introduced bike-sharing services. But sometimes, dreams are not so perfect.

It is true that it is convenient for people to go out by shared bike. As shared bikes become more popular, problems showed up. According to news reports, users treated shared bikes badly. After people used the bikes, some of them just threw them onto streets and even into the ditches (水溝). Some people stole the bikes or locked them up in chains (鏈條). A month ago, the police fined a man in Shanghai 1,000 yuan, because he stole a shared bike.

Besides, the damage to the QR codes (二維碼) on the bikes has brought huge losses to bike-sharing companies, like Mobike (摩拜單車). If the QR code is bad, people cannot use the bike anymore. It can take several hundred yuan for the company workers to find a lost bike and repair it. Mobike has 100 credit scores for each user. Once the score drops to below 80, bike rental (租金) will go up five yuan per 30 minutes.

However, punishment may not be the best way to stop shared bikes from being stolen or damaged. Bike-sharing services will work better only if people follow the rules and show respect for the bikes.

【1】People can easily rent a shared bike with _________.

A.It is unnecessary to have shared bike in the city.
