But when she woke up, she found that she had a big red pimple on her nose! She worried about it so much that she told me she didn't want to go to school. I knew that she felt embarrassed about having a big red zit on her face, especially when she was about to meet new friends and wanted to leave a good impression on them.

Among the causes of their unexpected deaths, roadkill ranks at the top. In Taiwan, the revealed statistics are rather shocking. According to a five-year survey by the Taiwan Roadkill Observation Network (TaiRoN), approximately five million animals become roadkill each year, involving 550 different species. Between 2012 and 2017, it was found that 54 leopard cats, 257 palm civets, and thousands of cats, dogs, and reptiles perished under the rolling wheels of the motor vehicles. TaiRON originated from a Facebook group created by concerned citizens in August, 2011. The group members come from a variety of locations and academic backgrounds rather than from any particular group or association. It is not an intentionally planned, research-oriented citizen science project. Rather, it is gradually established through discussions and consensus among members. There are four tenets guiding this organization: roadkill mitigation, citizen science, environmental education and life cherish. To encourage people’s participation in the program, TaiRON specifies four easy steps as follows: 1 Turn on GPS on your phone and take sharp photos when you encounter dead (wild) animals in the field. boll N ebonobo 、 20 Upload the photos and information (dates, latitude and longitude etc.) to the database and Facebook by APP. 100 robilo 3 Collect the complete carcass carefully with 2 layer zipper bag, label with information, and then put it into solid cardboard boxes or Styrofoam. 4 Use 7-ELEVEN “Frozen Shipping, Home-Delivery" and "C.O.D.

As Taiwan's only surviving wild cat, this feline species faces death threats from habitat loss, pesticides and car traffic, the last of which is the most serious one. Leopard cats are often found struck and dead on the roadside. By publishing roadkill statistics on leopard cats, TaiRON has championed the protection of this endangered species. Due to their unyielding efforts, there has been a significant drop in leopard cat deaths. toitained and odd or how Torloni 第四回 g 41

B C 閱讀測驗1 There he flies, turns, lands and—to da- a disaster is saved, by Superman. “Come on,” you roll your eyes. “That's NOT real.” But admit it -we LOVE superman. Since the debut of the prototypical superhero Superman in 1938, stories of various superheroes have dominated American comic books and crossed over into such other media as films and animations. Versatile as these super characters may be, they do share certain traits. We know the double-life secret that Peter Parker is Spider-man, Bruce Wayne the Batman, and Clark Kent the Man of Steel. The secret identity has a civilian job while the “super-me” puts on an eye-catching costume, or custom-made accessories like Wonder Woman's bracelets. We are concerned that the bad guys play tricks so as to hurt these protectors. Fortunately enough, our superheroes normally have a base to go for “restoration” to. The Batcave has everything the Batman needs. Isn't that great? Furthermore, these super icons may have some backups and do not always have to work independently. The Fantastic Four or X-men team up as they have common origins or sponsors. These super teams are like a marvelous circle. Nevertheless, there are downsides being a superhero. Credits are not always given as the Batman and Spider-man meet with public skepticism or outright hostility. A superhero may even lose control as the Hulk has an issue with his violent alter ego. We love to see the superheroes think big and achieve big. They for sure reflect what we are and what we want to be. In summary, superheroes are popular and iconic because they each represent a large part of a society's traits and values. Everyone can relate to at least one hero and villain, because those heroes are designed to show the best parts of society, and the villains represent the worst parts. 5 What can we say about the author's tone? (A) Angry. (B) Formal. (C) Harsh. (D) Relaxed. 48 主题5 藝文世界

By paying more, they can also guarantee the safety of workplaces, and be farmers adopt eco-friendly fertilizers to protect the environment. However, although the fair trade system seems beneficial to farmers, and trades are on the increase, it actually leaves much room for criticism. For example, getting fair trade certification is expensive for small businesses and individual producers. They have to split their hard-earne money for being a fair trade member, which ends up being a burden for the poor producers that fair trade system originally urges to help. Such high administration fees inevitably lead to the result that products are sold at much higher prices which weigh on consumers. Hence, customer base around the world is limited, because not everyone is willing to pay extra fees when they can get products of the similar quality but with lower prices. Worst of all, the administration fees don't go to the suppliers but retailers. Although there are obvious advantages of fair trade system, its disadvantages are likely to form a vicious circle and may shrink the fair trade market, if the basic problem doesn't get tackled. 44 Which of the following is the best title for this passage?
