This hotel is located at the eastern shore of the Great Salar de Uyuni,near the world's biggest salt flat.Since the building and some furniture are made entirely of salt,there are some specific rules the guests should follow.For example,visitors are banned from licking(舔)the walls and they also should be careful with salt furniture.Typically,the Bolivians treat their guests to salty meat.

Das Park Hotel

Das Park Hotel,located in Linz,Austria,is actually a number of drainpipes(排水管)that have been turned into rooms.It's one of the greatest example of how people can reuse materials.Since the space of each room is about 2 square meters,there are only a bed,light,power and ventilation(通风设备).You should pay for the bathroom and kitchen equipment.It uses a wonderful sound-proofing material to protect from being disturbed by the outer noise.The hotel is only available from May to October.

Some African schools are adding programs that teach what officials are calling "soft skills" to students.Soft skills are personal qualities that help a person relate effectively to others.Officials say this kind of training can help students succeed in the job market and in life.

The training is being offered at the St.Bernadette Kamonyi Secondary School in Kigali,Rwanda.For weeks,its students have been visiting neighborhood businesses.The goal of these field trips is for the young people to learn what is necessary to secure a job.

For the secondary school students,this information is important.In a few months,they'll complete their studies and try their best to find work.One of the Rwandan students is 22-year-old Aminadab Niyitegeka.He says he will look for any job available.He hopes that what he learns in his work readiness class will help.Traditionally,secondary schools in Africa have spent more time on subjects like mathematics and science,largely ignoring areas like public speaking and teamwork.But that is changing.Schools are exploring new teaching models to offer soft skills and professional training.It is part of an effort to perpare students to become better communicators,problem solvers and citizens(公民).

Rwanda has started a work readiness training program called Akazi Kanoze Access.It means "work well done" in Kinyarwanda,the official language of Rwanda.The program has trained more than 20,000 students to help make them more appealing to employers.

Emmanuel Ntagungira is a teacher and works as a trainer for Akazi Kanoze Access.He often visits employers who have given jobs to high schools.The employers are very happy because the graduates are ready to work.He says he hopes the program will help lower unemployment,which stands at over 13 percent nationwide.He also explains that the graduates have a healthy mindset and employers are satisfied with the job they've been doing.

5.Why do St.Bernadette Kamonyi Secondary School students visit neighborhood businesses?______

A. To find some suitable jobs for them.

B. To explore new learning methods.

C. To help the neighbors with daily affairs.

D. To learn some skills to get a job.

6.What do secondary schools in Africa traditionally focus on?______

A. Subjects like mathematics and science.

B. Public speaking and teamwork.

C. Communicating skills with employers.

D. New teaching models and skills.

7.What does Emmanuel Ntagungira think of the program?______

A. Instructive.

B. Beneficial.

C. Persuasive.

D. Controversial.

C

Do you ever find yourself spending time on product reviews when you buy something online,only to find that the product you bought is junk(废物)?New research led by Dr.Powell of Stanford University may explain why this happens:it boils down to the number of reviews a product has.

The study found that when choosing between two products online,people tend to favor the one with more

reviews despite the fact that the more reviewed product is of lower quality.This is because when shopping online,consumers engage(从事)in a type of "social learning",where they learn from observing the decisions of other people and the results of those decisions.People attach more importance to the choices of others.When evaluating online products,the item's rating and number of reviews can be helpful to an unsure customer.But a new study,published in the journal Psychological Science,found that consumers don't check those figures to learn their true meaning enough.So they fail to do a simple task when viewing online rating and reviews,leading them to purchase products of poor quality.When shopping online,consumers engaging in social learning become informed from the decisions of others.For example,you're more likely to buy a book at the top of the New York Times' best-sellers list or buy an app that's been downloaded millions of times.But looking at other people's choices is only a part of social learning.However,how people understand or fail to understand this data is affecting their decision-making in a negative way.Overcoming this bias(偏见)is difficult because consumers find comfort in popularity.

Powell and his colleagues also found evidence of this trend beyond the study."It doesn't necessarily mean that better things don't become more popular,but as a consumer,when you're looking at the number of reviews,it's not telling you anything," said Dr.Powell.

8.What does the underlined phrase "boils down to" probably mean?______

A. is equal to

B. results in

C. is due to

D. focuses on

9.What belief do unsure consumers hold when purchasing products?______

A. Rating determines quality.

B. Popularity is good.

C. Bad reviews should be ignored.

D. More-reviewed products is poor.

10.What do Dr.Powell's words mean in the last paragraph?______

A. The product's rating often fails to reflect true quality.

B. Usually consumers will find much comfort in popularity.

C. Consumers should distinguish good things and bad things.

D. Consumers should follow others when buying things online.

11.What is probably the best title of the text?______

A. How to Purchase Online

B. Why We Buy Junk Online

C. Why We Ignore Bad Reviews

D. How to Review a Product

D

Google's self-driving car is designed to work without a gas pedal(踏板)or steering wheel(方向盘).Now,the company has confirmed that the car doesn't have any windscreen wipers either,because there's no need for passengers to see where they are being driven.

The car requires no input from a driver,other than telling it the destination.There is no driving in the way we know it and all people inside the cars will be passengers who can spend their time paying no attention to the road.While the car may not need windscreen wipers,the lack of them may make passengers feel helpless if they are unable to see where they are going clearly.

Google's two-seater "bubble" cars have buttons to begin and end the drive,but no other controls.An on-board computer uses data from sensors,including radar(雷达)and cameras,to make turns and navigate its way around pedestrians and other vehicles.Under the vision made public by Google,passengers might set their destination by typing it into a map or using commands.The new car can't go faster than 25 miles per hour(40

km/h).It is electric and has to be recharged after 80 miles(129 km).They can only be used in areas that have been thoroughly mapped by Google.

Google has been testing its self-driving cars since 2009 and its steering wheel-less sample since early this summer.It intends on making its driverless cars available to consumers in the next five years.The ultimate goal of the project is computer-controlled cars that can get rid of human error,which results in about 90 percent of the 1.2 million road deaths that occur worldwide each year and it was also inspiring to start with a blank sheet of paper.

12.Why may people feel helpless riding in Google's self-driving car?______

A. They have no idea of the destination.

B. There are no other controls.

C. They are unable to see the road clearly.

D. The car is traveling too fast.

13.What's the main idea of the third paragraph?______

A. The tests the car needs to pass.

B. What the drivers need to drive the car.

C. The development of the new car.

D. How Google's self-driving car works.

14.How long can Google's self-driving car travel before being recharged?______

A. 25 miles.

B. 40 miles.

C. 80 miles.

D. 129 miles.

15.What can we learn from the last paragraph?______

A. Google began to test self-driving cars this summer.

B. The majority of the road deaths are caused by drivers.

C. Driver less cars will be available to consumers next year.

D. Google's computer controlled cars fire the drivers' inspiration.
