Reading
1. On the other hand, some scientists point out that if you clone an embryo, you can produce valuable human tissues---such as bone or lung tissue—that could be used to save human lives. On the other hand, many people, including some scientists, disagree and are afraid that, if mankind toys with nature in this way, we may be on our way to producing a real-life Frankenstein’s monster.
(1) on (the) one hand…on the other hand…一方面…另一方面…
On one hand, rapid development of the economy will improve the living conditions of people. On the other hand, it will speed up environmental destruction.

(2) point at，point to和point out的意思都與“指”有關(guān)，但還是有一定區(qū)別。
point at習(xí)慣上表示指向離說話人較近的事物，意為“指著”，at是介詞，著重于指的對象。point to多用表示指向離說話人較遠(yuǎn)的事物，意為“指向”，to也是介詞，著重于指的方向。point at可分開使用，point后直接跟名詞或代詞作賓語，at表示方向，而point to卻沒有這種用法，但它還表示“顯示、說明”的意思。
point out表示的是給某人指示方向，要點或錯誤等，意為“指出”，out是副詞。
