As is known to all, we live in a world of germs（细菌）. It is impossible to avoid exposure. Genetic makeups may give some people {#blank#}1{#/blank#} advantage over others. However, it does not stop people {#blank#}2{#/blank#}(become) sick.

    All of us have been a victim of an {#blank#}3{#/blank#}(ill) at some point in our lives. Moreover, it is likely that we {#blank#}4{#/blank#}(get) sick again in the future. Our best chances of avoiding sickness {#blank#}5{#/blank#}(be) by exercising and employing good {#blank#}6{#/blank#}(habit).

    While good hygiene and exercise serve as obvious advice to most people, eating healthily is not always obvious. If you cannot define ＂healthy＂, then your immune system will be happy {#blank#}7{#/blank#}(tell) you. The immune system is the foundation of our health. It works for us every day to keep us well. Ask yourself: ＂Are you making its job easier {#blank#}8{#/blank#} harder?＂

    Like any system, the immune system is no {#blank#}9{#/blank#}(difference). It has a tolerance too. If you eat unhealthily, your immune system will make you aware of it.

    Take a step {#blank#}10{#/blank#} the right direction by including some healthy food in your diet.

    Friendship is one of the most important things in everyone's life. {#blank#}1{#/blank#} is very difficult to find a better definition of friendship. A true friend is the person {#blank#}2{#/blank#} can share all our sorrows and double all our joys. In time of trial(尝试) , he or she is always at our side to give us his or her help and comfort.

    Knowing how {#blank#}3{#/blank#} (value) friendship is, we should be very careful with our choice of a friend. We should choose those people with a good character as our friends, but we must try to avoid {#blank#}4{#/blank#} (make) friends with a bad man. Besides, we should forgive their mistakes and try to help them as much as possible.

    A true friend can {#blank#}5{#/blank#} (trust), loved and respected. If you tell a friend your secrets, he or she won't tell {#blank#}6{#/blank#}. Friends share their happiness and {#blank#}7{#/blank#}(sad). They help each other when they are {#blank#}8{#/blank#} trouble, and cheer each other up when they are sad. {#blank#}9{#/blank#} most important thing is that a friend always understands you. In conclusion, {#blank#}10{#/blank#} you have made a good friend, don't forget him or her.

Is Hothouse Earth Avoidable?

    Nearly 50 years ago, the Club of Rome's report "Limits to Growth" warned that if economic growth continued fast without regard for the environment, the world could face ecological and economic collapse in the twenty-first century. Yet that is essentially {#blank#}1{#/blank#} has happened. As new research for the Club of Rome shows — and the latest report from the United Nations Intergovernmental Panel on Climate Change (IPCC) states — the world {#blank#}2{#/blank#} well be headed towards disaster.

    Many wrongly {#blank#}3{#/blank#}(interpret) the "Limits to Growth" as an attack on uncontrolled economic expansion. In fact, the report argued that {#blank#}4{#/blank#} the unlimited-growth pathway was chosen, it would require complementary policies (including funding) {#blank#}5{#/blank#} (preserve) the planet's limited life-support systems.

    This argument {#blank#}6{#/blank#} (ignore). Instead, the world has continued to pursue fast growth, without regard for the environmental consequences. This has enabled us to make enormous progress in reducing poverty, increasing longevity, and increasing wealth. {#blank#}7{#/blank#} it has come at a high cost to the formation of the society and the restoration of the planet.

    As scientists have conclusively shown, in the last decade, we have entered a new geological era, the Anthropocene, in which human activity — in particular, economic activity — has been the dominant factor {#blank#}8{#/blank#}(influence) Earth's climate and environment. In the Anthropocene, our planet's life-support system is changing faster than ever.

Climate change now represents a clear and present danger. If our planet becomes just 2℃ warmer than pre-industrial temperatures, we may be placed irreversibly on the path toward "Hothouse Earth" — a situation {#blank#}9{#/blank#} temperatures are many degrees warmer than today, sea levels are considerably higher, and extreme weather events are {#blank#}10{#/blank#}(common) — and more destructive — than ever.

    The Hong Kong –Zhuhai–Macao Bridge, the world's {#blank#}1{#/blank#} (long) cross-sea bridge, enters the history of human engineering and connection as a point of pride upon {#blank#}2{#/blank#} (it) opening to traffic at 9 a. m. on Oct. 24, 2018.

    One day after the opening was announced at a ceremony {#blank#}3{#/blank#} (hold) in Zhuhai, the bridge's ports in three different administrative regions started serving travelers around the clock, opening 24 hours a day, seven days a week. {#blank#}4{#/blank#} (ensure) faster boundary crossings for passengers, the Macao and Zhuhai ports jointly use a one-off immigration model, {#blank#}5{#/blank#} allows travelers to queue up only once to finish both exit and entry procedures of the two cities in about thirty {#blank#}6{#/blank#} (second).

    Apart {#blank#}7{#/blank#} private cars, taxis and goods vehicles, two types of public transportation—shuttle bus and cross-boundary coach—can also run on the HZMB. {#blank#}8{#/blank#} frequency of shuttle buses is about 5-10 minutes during peak hours. Booking tickets for the shuttle bus online in advance {#blank#}9{#/blank#} (be) available since 9 am on Tuesday. With the bridge now in service, the travelling time between Zhuhai and Hong Kong International Airport will {#blank#}10{#/blank#} (shorten) from 4 hours to 45 minutes.

    During the past ten years, traditional Chinese medicine (TCM) has been gaining {#blank#}1{#/blank#} (popular) across the world. This style of health care has spread to 183 countries. Up to now, approximately 100 international agreements {#blank#}2{#/blank#} (sign) with Chinese government on TCM cooperation. One of the reasons for such a growing trend is probably due to the increase of {#blank#}3{#/blank#} (science) research into TCM. Since Tu Youyou, a Chinese scientist was awarded Nobel Prize for her discovery of the drug qinghaosu, TCM has become even more{#blank#}4{#/blank#}(globe) famous. While quite a few {#blank#}5{#/blank#} (explain) have been given to support TCM theories, it is still faced with the challenge in {#blank#}6{#/blank#} (prove) to the public that it has certain effects when used in medical treatment. That's to say, it is significant in {#blank#}7{#/blank#} long run for TCM to team up with Western medicine. Scientists hold the belief {#blank#}8{#/blank#} using the collective knowledge, rather than regarding the two approaches {#blank#}9{#/blank#} being in competition is where the potential for its enormous effects {#blank#}10{#/blank#}(lie) in.
