高二英语单项填空困难题查看答案及解析

The bike-sharing companies that are powering a transportation revolution in China’s urban centers are not like those in the rest of the world. Their bikes have no docking ports or assigned zones for parking. Instead, riders open their smartphone apps, hop on, and start riding. So easy!

In 2015, Ofo, China’s bike-share pioneer, launched its first fleet of bicycles in Beijing. The bikes’ bright yellow frames were soon met by the orange-rimmed（镶边）, basket-equipped models launched by Mobike, Ofo’s main competitor today. In little over a year, the two companies have had a huge impact on revitalizing (重振) cycling in China, particularly among young people.

Ofo placed 1 million bicycles across 35 cities and registered 15 million users in its first years, while Mobike has now gained more than 10 million unique users and bicycles in 21 cities. Inspired by their success, at least 10 other companies have jumped into the market, launching their own app-powered, brightly colored bikes in quick succession. But Mobike and Ofo are far ahead of them.

The two industry leaders each take a different marketing method to a similar product. The Mobike app uses GPS to display bikes’ locations to users. They can use the map to reserve a bike and walk over to it. A scan of the bike’s QR code (二维码) unlocks the bike, and when users manually（手动地） lock the bike at the end of their trip, the app records the trip’s end and the bike will pop back up on the map as available. Equipped with this wireless technology, Mobikes cost between 1,000 and 3,000 yuan. Rides cost 1 yuan for an hour or a half hour, depending on whether a user chooses a “Lite” or regular bike, and the deposit (押金) required to the service is 299 yuan.

Ofo, meanwhile, is devoted not just to producing its own bikes, which have slim yellow bodies and cost about 250 yuan, but also to connecting existing bikes to its network----- a philosophy that begins with the practice of 2000 bikes offered to a campus bike-share program. The 2000 bikes were the first generation of Ofo. Yet the majority of the company’s bikes are currently ones that have been specially manufactured and fitted with their lock system. Unlike Mobike,Ofo bikes themselves are offline: their locations are tracked through users’ cell phones. Users find a free bike, enter the license plate number into their app, and receive the bike unlock code. When they have reached their destination, they end the ride on the app and manually lock the bike. Rides cost 1 yuan for an hour and the deposit is 99 yuan.

1.Which of the following statements is TRUE according to the passage?

A. The bike rides based on apps are available whenever you need.

B. The bike body in bright color only attracts young people to choose cycling.

C. Ofo knows their bikes’ location by scanning the bike’s QR code.

D. The bikes are locked automatically when the users reached their destination.

2.Which of the following is close to the meaning of the underlined word “succession ”in the 3rd paragraph?

A. successful experience.　　 B. movement to action.

C. continuous process .　　 D. production line.

3.How are Ofo bikes different from Mobikes?

① no need for online condition.

② without their own lock system.

③ not only to produce ofo bikes but also put existing ones to use.

④ to unlock the bike through app.

⑤ to lock the bike by QR code

A. ①②⑤　　 B. ②③④

C. ②④⑤　　 D. ①③④

4.What is the best title of the passage?

A. Bike-sharing business models: Mobike and Ofo.

B. A real transportation innovation（创新）: app-powered bicycles.

C. The successful secret of two bike-sharing companies.

D. Cool experience of app-powered bicycles.

There are 70,000 pubs in England and Wales have several thousand more in Scotland.

Every country has its drinking shop, but none has an institution quite like the British pub. The most important feature of a good pub (which modern buildings hardly ever achieve) is a feeling of something private. It must have nooks and crannies, corners and snugs, where conversations and assignations can take place without the whole world listening in.

Most pubs have at least two separate bars. The “public bar” which is for ordinary and women is the basic drinking shop. The “lounge bar” (or saloon bar) which is for traveling salesmen and “ladies” probably has a carpet on the floor and rather more comfortable decoration. There may be a difference of a few pence in the drink prices, although all pubs are required by law to put their price lists easily seen on display.

Pubs have been changing over the past few decades. More and more of them sell good, inexpensive food and are competing strongly with restaurants. Tea and coffee are often on offer and children are being made more welcome. The law says that no one under 14 may enter a pub, and between 14 and 18 they must be accompanied by an adult and may not buy or consume alcoholic drink. In reality some pubs, especially in country districts, welcome whole families. Some set aside special rooms for children and where there are gardens they are almost always welcome.

The most basic change, however, came about in the 1938 licensing laws which allowed pubs in England and Wales to open not just at lunch time and in the evening, but all day, from 11 a.m. to 11 p.m. (Scottish laws already permitted all day opening.)

1. Which of the following can be the best title?

A. Pubs’ history                        B. Pubs in Britain

C. Changes of pubs                          D. Features of a good pub

2. According to the British people, what kind of pub is a good one?

A. The one with all day opening time.

B. The one with good and inexpensive food.

C. The one with all kinds of people enjoying themselves.

D. The one with different parts where people can have a private conversation.

3.In paragraph 4, we can learn that ________.

A. pubs allow people above 14 to enter alone

B. pubs never allow people under 18 to enter

C. pubs don’t sell more expensive food than restaurants

D. pubs often sell alcoholic drinks as well as tea and coffee

4.According to the passage, which of the following is NOT true?

A. The law requires all the pubs have slightly different prices of drinks.

B. Ordinary people and women are often having fun in the “public pub”.

C. In some country pubs, children accompanied by their parents are always welcome.

D. Scottish laws allow pubs to open not just at lunch time and in the evening, but all day.

There are several reasons for hair loss in women. However, in most cases, treatment is quite effective. Female hair loss patterns in women are not as easily recognizable as they are in men. A woman may experience it temporarily(暂时地) due to pregnancy or illness, although they may experience it for other reasons.

Hair loss can be due to a variety of factors, including a genetic tendency ( which is not genetically linked to just one parent—both parents contribute to the tendency to lose hair).

Women who are experiencing hair problems seem to have more limited choices than men. There are some female hair loss treatments that are available such as the Tricomin System which is a topical treatment that is nutrition based. Shen Min for Women is another natural treatment that contains herbs (草药) that are said to stimulate(刺激) hair growth and even restore hair that is graying to its natural color.

The majority of the popular, proven hair loss treatments are only intended for men and are not suitable for women. True, a woman’s hair issue is different from a man’s. The biological makeup is different and the needs are different. Women have different needs and their bodies react in different ways to environmental changes, physical illness and even the treatments that are available. There are many natural treatments such as vitamin and mineral supplements that are said to stimulate hair growth, but, for the most part, these claims are currently unproven.

One of the first and most important factors to effectively treating is to get a diagnosis from a doctor. Talk to your doctor about any symptoms that you may be experiencing in addition to the thinning hair. Stress, weight loss or gain, illness and depression, all of these can be contributing factors.

1.It can be learned from the 1^st paragraph that ___________.

A. usually hair loss is hard to heal

B. female hair loss is more common than the men’s

C. women tend to suffer from hair loss during the pregnant period

D. only illness contribute to hair loss

2.Which of the following statements matches the text about the two treatments?

A. Both are to solve the problem of male hair loss.

B. Tricomin System is effective in speeding the growth of the new hair

C. Shen Min is an updated way of treating hair loss

D. The former is nutrition-based, while the latter is medicine-based.

3.The reasons for the differences between the female and male hair loss problems do not include ______________.

A. The biological structure and composition of the hair

B. The wants and needs

C. The reactions and responses to the outside changes

D. The approach to taking exercise

4.The natural treatments __________.

A. include vitamin and mineral supplements

B. are applied to keep the hair healthy

C. have been proved useful

D. are the most commonly-used ways

Taxpayers in America pay less in income tax than many Europeans, according to a Pew Research Center report. Belgium has the highest income tax rate, at nearly 56 percent of income, according to the Organization for Economic Cooperation and Development, or OECD. Taxpayers in the U.S. pay less than 36 percent of their incomes into the national treasury. Taxes pay for services provided by the government. The U.S. ranks 25 of the 34 developed countries polled in the report.

There are many differences between America and China. The biggest difference is traffic rules. In America there are too much more cars than in China. But there are much fewer traffic jams and accidents in America than in China. We hardly see traffic police in the street, but all cars obey strictly traffic rules, and people hardly find that a car does not obey traffic rules in the street.

About American traffic rules, there are many better terms, such as:

1. Stop line: There are stop lines in all crossing without traffic light (some have two stop lines and others have four stop lines). All cars must stop while meeting the stop line.

2. Traffic light: There is traffic light in the crossing of the road. Cars may almost turn every direction. The traffic light can give signal step by step including u-turn. There is a kind of middle lane of turning left. When a car wants to turn left in the road, he may enter into the middle lane of turning left and give a signal of turning left. When he thinks being safe, he may turn left. In many conditions the order of passing is also given very specifically. If people want to change lane or turn, they must look behind and think being safe. Only so, they may do it.

3. Specific item: Such as parking, there are three kinds of lines (their colors are white, blue or red) in the roadside. Every line may park different kinds of cars. There are many streets in some residential areas (住宅区), and there is a kind of rule that any car cannot park at any time or any period time. In every parking, there are some special positions for invalid (伤残的) people.

4. About the priority of passenger and car: At any case, passengers have the priority to cars. And only after passengers have passed the road and got the top of sidestep, cars may go ahead.
