【推荐1】Shenzhen, Jan 1st, 2018—Shenzhen has become the world's first city to make about 16,359, run on electricity(电；电能）. 12,518 taxis in the city are electric ones. "We will replace（替换）the rest of the taxis with electric ones by 2020." said Mr. Chen from the government.

"I have been a driver for twenty years," said Mr. Zhang, a driver who started to drive electric buses a month ago. "We had a lot of training and passed strict exams before we were allowed to drive the electric buses."

The city has built 8,000 charging poles（充电桩）and 501 bus charging stations. "A bus can be fully charged in two hours and the charging poles can serve 300 buses a day at our station. Since the replacement, the bus station has become quiet." said Mr. Guan, the manager of Qinghu Bus Station.

The use of electric buses and electric taxis plays an important role in making air fresher. In a year, the electric buses use 72.9 % less energy than the traditional ones. The electric taxis will save the energy of 119,000 tons of standard coal.

Shenzhen was one of the first 13 cities to take part in the National New-Energy Vehicle Program . In 2017, the city spent 3.3 billion yuan on electric buses and the charging equipment（设备）. The city also encourages people to bus new-energy cars or electric cars by spending less money.

【推荐1】Our new foreign students are going to arrive very soon, and here are some ways to communicate with them politely.

How close do you stand when you talk to a friend? You can stand close to people in the Middle East, but don’t stand too close to North Americans! Give them more personal space.

Do you know how to touch people correctly? Chinese girls often walk arm in arm with their friends. South Americans sometimes hold your arm when they talk to you, so you can’t move away! But in Britain, many people don’t like other people to touch them at all.

Do you look at people when you talk? In some places, it isn’t polite to look at people when you talk, but in other countries it isn’t polite to look somewhere else. In Britain and the US, people usually look at each other when they talk.

And how do you say goodbye? That’s easy, wave (挥手) to say goodbye. But be careful! In Greece, it’s not polite at all! In fact, it’s very rude!

【推荐2】International tourism is becoming more and more popular. Large numbers of people from all over the world come to visit famous places, such as the Great Wall of China and the Sistine Chapel in Vatican City. These visitors are instrumental in the local development, but at the same time they have caused many problems. They’ve thrown rubbish everywhere, brought more traffic and even done serious damage (破坏) to these places.

As for the damage, there are many different causes. For example, the paintings in the Sistine Chapel are being damaged because people breathe onto them when they visit. Damage in other places such as the Great Wall is serious partly because tourists climb on delicate (脆弱的) areas. Even though some of the walls were built of stone, after so many years, they are already in poor condition and need to be rebuilt.

What can we do to deal with these problems? On the one hand, we have to cut down tourist numbers, because fewer visitors will result in less damage. On the other hand, we should make strict rules about which areas people can visit and what they can do when they get there. For example, visitors should not be allowed to walk off the special paths. Visitors to indoor places can be asked to wear masks to protect the paintings.

It is necessary to control tourism in famous places. If we do not do this, these places will disappear from our planet. And people who live hundreds of years later will have no chance to see these great places.

【推荐3】In Britain you may often hear “Drop in any time” or “Come to see me soon”, but you can’t really do that. People just say those things to make you feel welcome. It is better to telephone before visiting someone at home. If you receive a written invitation to an event that says “RSVP”. You should reply to let the person who sent the invitation know whether or not you plan to go.

You should never accept an invitation unless you really plan to go. You may refuse by saying, “Thank you for inviting me, but I will not be able to come.” If, after accepting, you are unable to go, be sure to tell those who are expecting you as soon as possible that you will not be there.

Though it is not necessarily expected that you give a gift to your host, it is considered polite to do so, especially if you have been invited for a meal. Flowers, chocolate, or a small gift are all appropriate（合适的）. A thank-you note or telephone call after the visit is also considered polite and is an appropriate way to express your appreciation for the invitation.
