What would the world be like if cars could drive themselves? Imagine seeing an empty car passing by on its way to pick up its owner, or a car full of passengers who are reading, listening to music or even sleeping. But none of them are worried about the road ahead.
Well, all of this could be the future of driving. There are several companies, including Google, working on driverless cars. So far, no Google self-driven cars have gotten a traffic ticket (罚单), but some of them have been in accidents when other cars hit them.
These cars are now still in the testing stages (阶段). But, if the tests are successful, these electric self-driven cars could be put into use very soon.
The cars are so special that they can take the place of drivers during certain situations. They are able to park themselves, or slow down when they notice objects close by. They can also control the speed if there is danger.
Scientists and engineers believe, with the help of wireless signals (无线信号) , cameras and GPS, creating a safe self-driven car might be possible. The cause of deadly (致死的) road accidents is usually careless drivers or bad conditions. The self-driven car may be able to prevent these. However, some people don’t like the idea. American lawyer Whit Drake does not believe these cars are safe. He thinks that technologies can also be mistakes.

Do you often use plastic straws (吸管)? You probably use them to drink lots of things, such as cola or milk tea 1. They are made in 10 minutes, used in 20 minutes and remain on the earth for over 100 years since they can't be broken down (分解) easily.
But how do plastic straws get into the ocean? Through human mistakes, they are often thrown everywhere. The waste management in some areas is so poor. All gutters (排水沟) lead to our ocean 2. Once a turtle was found bleeding because a 12-centimeter-long plastic straw was pushed into its nose. How terrible!
3. That is enough to circle nearly two-and-a-half times around our planet! If we didn't act now, there would be more plastic in the ocean than fish by 2050.
Luckily, more and more people around the world have realized this problem. They begin to consider if they really need to use plastic straws when drinking drinks.
So what can we do to reduce (减少) plastic pollution? 4. For example, next time you go to a restaurant, make sure you order your drink without a straw. What if people need to use a straw? There are reusable straws that can be cleaned and reused instead.
Starbucks (星巴克) has started to offer straw less lids (盖子) and paper straws instead of plastic straws in almost 1,000 stores in Shanghai and Shenzhen. Starbucks is not alone. 5. It is hoped that more businesses and customers will play a part in protecting our environment.
