Let’s ride bicycles

Good morning, everyone! I’m Jack from Honor Senior high school. The topic of my speech is “Let’s ride bicycle”.

As is known to all, with the     1    (improve) of people’s living standards, cars have become a popular means of transport,     2    (bring) great convenience to our life.     3    , they have also caused some problems such as air     4    (pollute) and traffic jams.

How can we solve the problems then? As far as I am concerned, riding bicycles is a good solution. For    5     thing, bicycles don’t need     6    (some) petrol and they are energy-saving. For another, bicycles are environmentally     7    (friend) because they won’t give off waste gas. What’s more, riding bicycles is a good way for us     8    (exercise) and it is beneficial to our health.

Therefore, let’s take the responsibility to build up a low-carbon city by     9    (ride) bicycles. Come on and     10    us !

Thank you!

Air pollution is a killer. The World Health Organization says it kills about seven million people around the world each year. Even if    1    (pollute) air does not kill us, it can make us very sick.       2    (wear) face masks, people walk past heavy traffic as Beijing is hit by a sandstorm. The government in Beijing issued a blue warning on air pollution as sandstorms swept through the Chinese capital city.

However, breathing in dirty air    3    (frequent) may do more harm to your body,    4    can also affect your brain and your ability to think. A new study shows that air pollution can cause a huge decrease in our    5    (intelligent).The researchers reported that long term suffering air pollution can affect a person's mental abilities in two    6     (area):language and math.

The researchers studied about 25,000 people from across China. Between 2010 and 2014, these Chinese men, women and children     7    (give) language and math tests. The researchers found that breathing in     8    air which has been polluted can reduce a person's education level by about one year. The effect generally is even    9     (bad)for those over years of age, for men and for those with little or no education. The researchers noted that the effect of pollution    10     language ability is even more serious as people age, especially among men and the less educated.

The earth’s plants     1     animals become endangered every day. And many of them are     2     (die) out. If nothing is done, we may find     3     (our) alone on the earth.

Wild animals live in the forests     4     are being destroyed by people. As a result, the animals are losing their habitats. Besides, animals are short of food because of     5     (pollute). Even     6     (bad), buying leads to killing, too.

I suggest that measures should be taken     7     (protect) wildlife. First, we can try to raise people’s awareness to love animals, for they are our     8     (friend). Then the government should make laws, if someone hunt, they must     9     (punish). If we do so, I am sure humans can live in harmony     10     animals.
