Now that she is out of a job, Lucy ____ going back to school, but she hasnt decided yet.

A. had considered

B. has been considering

C. considered

D. is going to consider

解析：B 句意為：由于失業(yè)了，Lucy一直在考慮回學(xué)校學(xué)習(xí)，但還沒有決定。所以應(yīng)用現(xiàn)在完成進(jìn)行時(shí)態(tài)表示一直在持續(xù)的動(dòng)作。consider考慮，后接動(dòng)名詞作賓語。

2.People also travel to meet new friends, to try new kinds of food, to experience life in other parts of the world or simply to get away from cold weather.

1)experience可用作動(dòng)詞，意為“體驗(yàn)；有……經(jīng)驗(yàn)”。

Have you experienced real hunger? 你體驗(yàn)過真正的饑餓嗎？

Experiencing pain is as valuable as experiencing pleasure.

解析：C根據(jù)句意“從一萬英尺高空的飛機(jī)上跳下是一次非常令人激動(dòng)的體驗(yàn)”判斷experience應(yīng)為可數(shù)名詞，所以第二空要加不定冠詞an。第一空加不定冠詞an表泛指。

3.Watch out for dangers, such as spiders, snakes or poisonous plants.

1)watch out(for)=look out(for)意為“當(dāng)心；提防”。

Watch out for that man.

要提防那個(gè)人。

Watch out!Theres a car coming. 當(dāng)心！有車來了！
