14.MCDONALD'S,one of the world's largest restaurant chains,recently made a big decision.On March 9,the company announced that its chicken suppliers in the US would stop using human antibiotics within two years.
Antibiotics are medicines that attack harmful bacteria(细菌) to help cure illnesses.Many cattle,pig and chicken producers give their livestock(家畜)antibiotics to help them stay healthy.Feeding antibiotics to animals is legal in the US.But the producers feed their livestock not only animal antibiotics,but also those used by humans.Experts say it can lead to public health problems.Overuse of these human antibiotics could cause germs(微生物)to become resistant(抗体)to drugs.When the drugs are used to treat humans,they may no longer be effective.
Many US fast food restaurants already say they serve chicken which are raised without antibiotics,but the decision by McDonald's is important because of its size.The company has over 30,000stores around the world,including 14,000in the US.
In recent years,customers have started to care more about food ingredients(原料).If they feel certain foods are made with ingredients that are of low quality or don't meet certain levels of quality,they'll choose other higher quality foods.
After seeing customer visits to US stores drop two years in a row,McDonald's says more changes to their food could be on the way.
However,McDonald's won't be applying the new antibiotics policy to its Chinese stores soon.
The company said it's not a double standard but they have to take Chinese food safety standards into consideration.
"The measures will be carried out gradually,based on the actual situation of Chinese agriculture,"McDonald's China said in a statement.

11.Last month I got the chance to take part in an underwater research project in an area of the Gulf of Mexico called the Flower Gardens.A team of professional researchers,led by the scientist Dr.Matt Phillips,was trying to learn more about the fish and other creatures that live in this part of the sea.The Flower Gardens are a long way from the shore and we spent three days on a boat.
The team used a piece of underwater equipment called a Remotely Operated Vehicle (ROV) to collect information.The ROV could measure water depth and temperature and it also had a camera that sent live film back to the boat.The ROV was great fun.It was controlled by a computer on the boat,and I was allowed to operate it a few times.
However,the thing I enjoyed most was diving into the water.At first,I was quite frightened-mainly because I couldn't see land in any direction.But as soon as I jumped into the water,I wasn't afraid anymore.It was amazing to see the colourful fish swimming around and I could see all the way to the Flower Gardens,which are almost 30metres down.
I will never forget the Flower Gardens.The trip was like a holiday but I also learnt new things about science and research projects.The team were very friendly and everyone was happy to explain what they knew about the sea.It was a great opportunity and it has made me think about my goals in life.The experience will definitely encourage me to work harder to become a scientist.

76.When did the writer take part in the project?(不多于2个词)Last month.
77.What were the researchers trying to learn about in the Flower Gardens?(不多于5个词)The fish and other creatures.
