    您好, 提供以下見解供您參考:

    1. 因為這句的主詞是 "gateway drugs." Drugs, 用了複數, 所以後面的動詞 lead 用原式. 不是用 leading 的原因 ... 這麼說好了, 這個句子是兩個句子的合併, 分開來說的話可以這麼說:

    Gateway drugs are substances people take.

    Gateway drugs lead them to take more drugs.

    第二句要用 leading 的話, 缺了個 be 動詞對不對? 所以答案是 lead, 不是 leading. 第一句的 are 已經用在 drugs are substnaces 上了, 不是影響合併後子句動詞型態的因素.

    --------------------------------------

    2. 這句如果用 Since 開頭, 到 marijuana 就結束的話, 文法上是錯的 - 後面還需要有補充的句子才能算完整. Since 是有[因為...]或是[自從...]的意思, 用它起頭的話你後面要有說明. Such 常用來取代 it is 或是 this is 開頭的句子, 用意在強調該主詞.

    用中文翻譯的方法看看:

    用 Since 的話, 不完整:

    慣性酗酒者在一段時間後可能會覺得對酒精感到厭倦了, 而想要尋求更刺激的物品. 自從一個狀況常會引導青少年去嘗試其它如大麻的毒品. ( ... 然後呢?)

    用 Such 強調是[這個狀況]:

    慣性酗酒者在一段時間後可能會覺得對酒精感到厭倦了, 而想要尋求更刺激的物品. 這個狀況常會引導青少年去嘗試其它如大麻的毒品.

    Gateway drugs are substances people take that _ them to take more

    drugs.

    這裡有一個形容詞子句 people take that 修飾 gateway drugs are subtances

    所以 people take that 視為一個名詞 動詞就是 lead

    people 是複數 不需用三單

    Habitual drinkers may find alcohol not stimulating enough

    after a while and want to seek other more stimulating substances.

    ____ a circumstance often preconditions teenagers to the possibility

    of taking other drugs such as mauijuana....

    since 自從 後面接過去式

    as 當..... 由於.......

    all 全部的 所有的 通常置於複數名詞前面

    such 如此..的 , 這樣的 置於 a/an之前 後接句子

    所以選 such
