Firstly, exploring space has already made a difference in the fight against world hunger. It has directly resulted in the many satellites that now orbit Earth. A number of the satellites record data on land and weather patterns. Then the data is transmitted to scientists on Earth. After careful analysis, the scientists can provide useful recommendations and advice for farmers. As a result, space-based science has helped Farming in its efforts to grow enough food to feed Earth's increasing population.

Secondly, space exploration has already promoted technological improvements that benefit us all.High-end products around the world are made to a higher standard now because of advanced technology which was first created to meet the requirements for space exploration. For example, space technologies have helped the research and development of different types of new material. They have also helped companies make better heart monitors and other machines that doctors regularly use. Today, space technologies are widely used in all kinds of industries, and everyday products such as GPS, memory foam pillows, and smartphone cameras are changing our lives.

Finally, sending astronauts into space has helped people to think about the world' s problems and even to find ways to solve them. Seeing pictures of our planet as an island in a black sea made people realise that our planet's resources are limited. In order to provide for such a rapidly increasing population, scientists are trying to find other planets that could one day be our new home. The greatest attention at present is on Mars because it is closer to Earth in the future, humans may live on both planets.

Post-Reading
Space exploration is a Waste of Time and Money
Everyone gets excited by the news of the most recent space fights,and I too share
in people's sense of awe (敬畏) and wonder at the photos from space that we see.
Having said that, it is hard to believe that the high cost of space flight is justified
so that we can get some lovely pictures. We should be spending our money more wisely, on what people need.
I cannot understand spending all this money on expensive research and experiments when so many people need food.Around the world. millions of people
are hungry and dying of starvation. On the other hand, we hear on TV that for as
little as a dollar a day,a child in Africa can be saved.Considering the billions spent on space travel, it just seems a better investment to feed the hungry.
Post-Reading
Some people argue that someday we will have to go to live in space because the world will be made impossible to live in through pollution. This seems silly. When your house gets dirty, you spend the time and money cleaning it up. You don't
move house simply because you need to wash your windows or vacuum the floor. In the same way,it makes more sense to use our time and money to take care of our planet, rather than look for a new home.
Post-Reading
Finally, there are a lot of unsolved mysteries on Earth. So why are we going into space to explore There are still many things to discover in the ocean depths and
the Antarctic. But we do not even have to go that far: Science has yet to unlock
all the mysteries of the atom, and there are many realms of technology that we are just beginning to understand and explore.
In the end, it just does not seem a very wise investment to go to space. We have
too many needs here on Earth to be wasting our effort on space exploration.

[答案] Dear Tom,
How are you I'm glad to tell you that there will be a lecture so I am writing to invite you to my school to attend it. Let me introduce it to you.
The lecture is given by a famous professor named Mr Zhang next weekend in our school hall. The content of the lecture is about "black hole", which is a hot topic among people recently. So Professor Zhang is going to tell us
what caused the black hole and what effect it will result in on the whole world. In order to attend the lecture you are supposed to make full preparations for it. For example you'd better have a wide range of knowledge such as
geography, physics and astronomy.
I'm looking forward to your early reply. Welcome to my school. I'll meet you at the school gate.
Yours
Li Hua
