Unit 3 Science versus nature教案
Module5 Unit 3 Science versus nature語(yǔ)言點(diǎn)
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.
(短語(yǔ)) at hand 在手邊，在附近 by hand 用手；親手
in hand 手頭現(xiàn)有的，正在進(jìn)行，在處理中 hand in 交上來(lái)
hand out 分發(fā) hand over移交
hand down 把…傳下去 hand in hand手拉手

(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(shuō)話人較近的事物，意為“指著”，at是介詞，著重于指的對(duì)象。point to多用來(lái)表示指向離說(shuō)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(yǔ)，at表示方向，而point to卻沒(méi)有這種用法，但它還表示“顯示、說(shuō)明”的意思。
point out表示的是給某人指示方向，要點(diǎn)或錯(cuò)誤等，意為“指出”，out是副詞。
根據(jù)句意，用point at，point to或point out的適當(dāng)形式填空。
1.The teacher is pointing at/to the map on the wall.
2. Both the hour hand and the minute hand point to twelve. It was noon.

(4) on one’s (the) way to doing sth. “正在做某事的過(guò)程中,即將成功,離…不遠(yuǎn)了”. to是介詞，后接名詞、代詞或動(dòng)名詞短語(yǔ).
