   A new tool of communication called the "drift diary" is doing the rounds among young college graduates.

The "drift diary", like those ancient paper messages put into a bottle left to drift on the high seas to reach hundreds of miles away, connects lonely hearts. It was first started by a Beijing woman, who goes by the screen name Little S, in 2007.It has become the preferred tool of communication among youngsters afraid to reveal their innermost self to peers, but wanting to share their lives with others. The way it works is that the initiator(发起人)of the diary mentions it on popular Internet forums such as Tianya and Douban. Those wanting to react or otherwise add to the diary then send their real names and addresses to the initiator via e-mails or text messages.

The numbers in one group are usually restricted to between 30 and 50. The diary then is passed on to another by the express delivery or personal handover. The diary writers are mostly anonymous(匿名的)but if they wish to reveal their identity they can do so by posting their contact information at the end of their postings.

The diary writers not just add words but also decorate the plain notebooks with cartoons, drawings or even dress it up with a ribbon or a new cover. Interesting experiences, travel journals, the simple joys of everyday living or sweet recollections of childhood, all find a place in these diaries. Most often, though, the writers set down their frustrations and predicaments.

It usually takes one year for a diary to return to the initiator. The last recorder is the luckiest one, with access to all previous entries, while others can request photocopies of them from the diary's initiator.

【小题1】Why is the "drift diary" popular among youngsters?
A.Because they hate using the Internet.
B.Because they like to show themselves to peers.
C.Because they want to share their lives with strangers.

C.④⑤①②③D.①③⑤②④.

   A solar-powered car that can be charged as it runs is being tested in Germany.

Munich-based manufacturer(制造商)Sono Motors has built the new type, named Sion, and will likely help the European powerhouse hit its national target of 1 million electric cars on the road by 2020.

Sono Motors has solar cells fixed into Sion’s bodywork, with a total of 330 solar cells built into the roof, bonnet and sides of the vehicle. These enable the vehicle’s battery to be charged when sunlight is hitting the solar cells, whether it is on the road,or parked in the sunny spot in a car park.

The solar-powered vehicle is set to be launched in Germany in 2019.

Sono Motors wants Sion to be universal and allows the car to be charged using solar energy as well as conventional outlets(电源插座), so car owners aren’t left on cloudy days.

The firm has made a 2019 date for mass production,which will be undertaken by a European manufacturer. Some 6,500 people have already placed orders for the electric vehicle. Prices for Sion tend to start from € 16,000 next year. The all-electric vehicle will offer a range of around 250 km before the battery runs out completely and it needs recharging either by solar power or using a wall plug, the company said.

Sion was designed originally as an environmentally conscious car,but will also include a number of features designed around comfort to help it compete with other modern vehicles.

“We have a seat heater, air conditioning, and a large entertainment system where I can also connect my phone, which means I really have a full vehicle,” Laurin Hahn, co-founder of the company told Reuters.

【小题1】From the third paragraph we can know that ______.
A.the car is popular on the road
B.the car has a very large battery
C.there are 330 solar cells on the car
D.where there is sunlight, Sion can be charged
【小题2】What does the underlined word in Paragraph 4 “launch” mean?
A.designB.release
C.improveD.recall
【小题3】Why does the car not break down when it is cloudy?
A.Because it is made from the rainproof material.
B.Because it can be charged by clouds on cloudy days.
C.Because it can store a great deal of energy.
D.Because it can be charged by conventional power outlets.
【小题4】What are the features of the car?
A.Modern, powerful and popular.
B.Environmental, comfortable and competitive.
C.Environmental, cheap and simple.
D.Expensive, fashionable and energy-saving.
