Green Hills, Clear Water, Blue Sky is a project that was set up     1     the government three years ago. Since it was started, many people have taken part. They think it is their duty     2    (make) the Earth beautiful and     3    (peace). At the same time, they insist that the government should play     4     important role and try     5    (they) best to protect the environment. Some owners of factories are. damaging the environment by     6    (pollute) rivers with chemical waste. So it     7    (believe) that the government should pass laws to punish people     8     damage the environment. Besides, the government should build conservation     9    (center )so that plants     10     animals in danger can be protected.

All in all, people and the government should work side by side to take care of the Earth.

Whales have been facing serious danger for a long time.

First, due     1     the greenhouse effect, glaciers are melting, and some living creatures in the Antarctic and the Arctic are in danger of     2     (extinct). Besides, with global warming becoming worse, life in other parts of the ocean has also been     3     (constant) affected, including whales.

Secondly, whaling activity is another killer. Historically, whaling has been popular in some overseas countries, such as England, Japan and Norway.     4     (regard) whales as a money-making machine is the reason why some people’s whaling can’t     5     (stop) easily. A kilogram of whale meat can fetch about $ 100 in Japan. Besides, advanced technology has increased the efficiency of whaling and gradually reduced the number of whales. What’s more, some countries are still on whaling in     6     name of science.

The fact     7     whales have become endangered animals is alarming us. Some     8    (organization) have realized the importance of saving them and have begun working hard to do something for them. The international community     9    (make) a strategy against commercial whaling. In my opinion, governments should also make laws     10    (protect) whales.

The 21st century is dominated by more technology-oriented inventions than before. The 20th century     1    (see) man land on the moon. The 21st century will witness man landing on several planets. The first will be Mars, also     2    (call) the Red Planet. As planned by NASA, the mission can be achieved by 2030. That will set a precedent(先例) for explorations by future generations. Furthermore, increased investment in research is likely     3     (lead) to the discovery of a vaccine for AIDS.

Technology is advancing fast. Social media at present acts as one of the leading 64.    4    (source) of news and interaction,     5     has a negative influence on traditional media,     6    (particular) print newspapers. Social media will soon take over the market.

Mobile phones will play a greater role     7     the purchase of goods, as well as the withdrawing and depositing of money. Electronic money will replace paper money. In addition, with declining oil reserves across the world, electric cars will replace petrol cars in a few decades. As     8     result, there will be a major shift in job trends.

Global warming will become an even     9    (big) problem, with sea levels     10    (continue) to rise. Freshwater sources will be polluted. Fresh water will become a major issue. Hence environmental destruction will increase greatly.
