Global warming has caused a rise in sea levels,{#blank#}1{#/blank#}has increased the amount of salt in fresh water used on seaside farms. As a result, farmers are{#blank#}2{#/blank#} (increase) unable to use fields close to the sea.{#blank#}3{#/blank#}a farmer in the Netherlands is now using a mixture of sea and fresh water {#blank#}4{#/blank#} (grow) tasty vegetables.

    It is in his eight areas {#blank#}5{#/blank#}he teamed up with scientists such as George Hambley to make the first attempt. Separate {#blank#}6{#/blank#} (pipe) pumped mixed water. And a computer program controlled the levels of salinity and water{#blank#}7{#/blank#} (call) “Sensor”. The researchers said they were able to harvest vegetables from most of{#blank#}8{#/blank#}eight test areas. They said the vegetables were smaller than{#blank#}9{#/blank#}grown in fresh water. However, due to more sugar and salt in the water, they taste{#blank#}10{#/blank#}(good).

    Nobody wants to be aged, but {#blank#}1{#/blank#} it comes to visiting cities, most of us want to visit the world's oldest cities. Luoyang is one of the oldest and most {#blank#}2{#/blank#}(attract) cities in the world that I'd like to recommend to you.

    Luoyang stands out {#blank#}3{#/blank#} the oldest continually inhabited city in Asia. The city is considered to be {#blank#}4{#/blank#} birthplace of Chinese culture and history as well as being one of the Seven Ancient Capitals of China.

    With such a long and exciting history, Luoyang has really a lot {#blank#}7{#/blank#}(offer). The Longmen Grottoes, which {#blank#}8{#/blank#}(include) in the world Heritage List since 2000, and many historic Buddhist temples {#blank#}9{#/blank#}(constant) attract tourists from all over the world.

    Tea is one of the{#blank#}1{#/blank#}(much) popular drinks in the world. You make it by pouring hot water over the dried leaves of a tea plant. For {#blank#}2{#/blank#} (hundred) of years people believed that tea could cure illnesses, and they used {#blank#}3{#/blank#}as medicine. Today scientists know that tea contains chemicals that prevent cells from dying. Most teas have caffeine in them, {#blank#}4{#/blank#}makes you feel more active. Some people have problems{#blank#}5{#/blank#}(drink) tea because it can cause sleeplessness.

    The tea plant{#blank#}6{#/blank#}(grow) best in tropical and temperate places where rain falls throughout the year. Teas can be grown from sea level {#blank#}7{#/blank#}about 2,000 metres, but the best quality grows in higher regions.

    Tea comes from the leaves and buds of tea plants. Wild plants can be up to 9 metres high, however, on tea plantations,{#blank#}8{#/blank#}( pull ) the leaves {#blank#}9{#/blank#} (easy), people cut them back to a bush of about a metre in height. It takes a plant three to five years before it is ready for picking.

    A picker can harvest about 20 kg of tea {#blank#}10{#/blank#}day. On large tea plantations the leaves are harvested by machines, but the quality of tea is higher when the leaves are picked by hand.
