Here is an advertisement about four-day tour between Hong Kong and Macao.

    Lin Feng is a Grade 8 student in Hailing School. Last week he joined the four-day tour between Hong Kong and Macao with his parents.

The eco-house

    Simon Dale didn't want to live in a city's apartment building. So he made up his mind (build) his own home in the countryside. He moved to Wales with his family and built a wooden eco-house. With the help of his father-in-law, a builder, he moved into a (comfort) new home after only four months.only cost $4,700 to build the house.

    The eco-house is made of natural (material). Simon Dale and his father-in-law (dig) into the side of a hill and then used the mud and stone to make the walls. The floors (make) from wood from the nearby area. The design is open-plan. There is no central heating, there's a wood-burner and solar panels (太阳能电板) on the top can provide power for lighting, music and computing. Drinking water is from a nearby spring. The fridge stays cool, thanks air from under the ground. Simon Dale says, "We try to live in peace with the natural world." He has (certain) done his best to achieve that.

It's hard to turn down a tasty banana. They taste good and you don't have to wash them before eating them. However, British scientists say that the fruit may disappear by 2050.

One reason for this is climate change. Scientists at the University of Exeter collected numbers from 27 countries and areas that produce 86 percent of the world's bananas. They found that climate change has improved growing conditions in 21 of these countries. In the past 60 years, the production has reached 1.37 tons of bananas per hectare.

⑴ Ten of the countries, including India, the world's biggest producer of bananas, will produce fewer bananas. By 2050, the fruit may die out. ⑵ Shouldn't bananas grow more easily if it's hotter outside? ⑶ In fact, the perfect temperature for growing bananas is between 24 and 32℃. If temperatures get too high, they will stop growing. ⑷

Diseases (疾病) are another danger to bananas. Unlike other plants, the bananas we grow come from shoot cuttings (扦插) rather than seeds (种子). This means that all banana plants have the same genotype (基因型). In other words, if a disease is able to kill one plant, it could kill them all.

One serious disease is called Panama. Caused by fungus (真菌) in the soil, it spreads easily. It has spread across South Asia, Africa, the Middle East, and Australia. If one banana plantation meets the disease, it will take 30 years until it is able to grow bananas again. Scientists have yet to find a cure (治疗) for this disease.
