===TITLE=== UNIT 10: CLOZE TEST (DROPDOWN) :: 16 QUESTIONS ===TIMER=== 15 ===PART=== 1. READING :: 16 :: 1 ===SECTION=== Cloze Test Dropdown ===DROPDOWN=== **Passage 1** Our (1) {continent | polar region | nature reserve | *solar system}, which includes the Sun and eight major planets, is vast and fascinating. (2) {*Mercury | Earth | Venus | Mediterranean Sea}, which is the closest planet to the Sun, is extremely hot and has no atmosphere. Another interesting planet is (3) {coastline | *Venus | beaver | livestock}, which can often be seen brightly in the evening sky from our home. Human beings live on (4) {landform | outer space | *Earth | ocean}, which provides the perfect natural environment for life. However, we are currently facing (5) {science club | geology | fresh water | *global warming}, which drastically threatens the delicate ecological balance. As a (6) {*scientist | human | zebra | giraffe}, who studies outer space and the planets, Mr. Smith always emphasizes the significance of protecting our home. He states that without (7) {pesticide | *fresh water | moonquake | pollution}, which is essential for our survival, no human or animal could exist. Recently, his science club, which focuses heavily on astronomy, discussed the phenomenon of the (8) {food chain | habitat loss | *moonquake | flora & fauna}, which is similar to an earthquake but occurs on the Moon. ===DROPDOWN=== **Passage 2** On Earth, there is a wide variety of flora and fauna, which creates a very complex (9) {outer space | surface | liquid | *food chain}. For example, the (10) {*grassland | solar system | pole | moonquake}, which is a vast and flat landform, provides a natural habitat for beautiful wild animals like zebras and giraffes. Unfortunately, human activities such as using (11) {continents | *pesticides | nature reserves | planets}, which contain harmful chemicals, often pollute the soil and water. This directly leads to severe (12) {science club | giant | *habitat loss | Venus}, which endangers many species. Furthermore, people often (13) {launch | persuade | adjust | *cut down} old trees, which completely destroys the bamboo forest where pandas live. To maintain the ecological balance, we must establish more nature reserves. The (14) {*Mediterranean Sea | Mercury | outer space | geology}, which connects Europe and Africa, is a gorgeous water body but also faces serious pollution issues. We must all (15) {destroy | *make a contribution | threaten | pollute} to saving Mother Earth before it is too late. Our (16) {livestock | beaver | *role | liquid} in this fight is crucial. Giải thích: (1) solar system: Hệ mặt trời (bao gồm Mặt Trời và 8 hành tinh). (2) Mercury: Sao Thủy (hành tinh gần Mặt Trời nhất). (3) Venus: Sao Kim (nhìn thấy rõ vào buổi tối). (4) Earth: Trái Đất (nơi con người sinh sống). (5) global warming: Sự nóng lên toàn cầu (đe dọa cân bằng sinh thái). (6) scientist: Nhà khoa học (người nghiên cứu không gian vũ trụ). (7) fresh water: Nước ngọt (thiết yếu cho sự sinh tồn). (8) moonquake: Động đất trên Mặt Trăng. (9) food chain: Chuỗi thức ăn (tạo ra từ sự đa dạng hệ động thực vật). (10) grassland: Đồng cỏ (môi trường sống của ngựa vằn, hươu cao cổ). (11) pesticides: Thuốc trừ sâu (chứa hóa chất độc hại). (12) habitat loss: Sự mất môi trường sống (khiến nhiều loài gặp nguy hiểm). (13) cut down: Chặt đốn (cây cối). (14) Mediterranean Sea: Biển Địa Trung Hải (nối liền châu Âu và châu Phi). (15) make a contribution: Đóng góp (vào việc cứu Mẹ Trái Đất). (16) role: Vai trò (của chúng ta trong cuộc chiến này là cực kỳ quan trọng).
