2021年9月29日托福考試機(jī)經(jīng)完整版(2)
WRITING
Task1
Topic Reading
Captive- raised crows重新放回野生環(huán)境不成功,有三個(gè)原因:
1. Their vulnerability to predators. Captive-raised crows如果回到野生環(huán)境當(dāng)中,會(huì)很容易被
它們的捕食者,比如hawks,給捕獲;
2. They have difciltly in building nests to reproduce. Female birds在筑巢的過程中總是會(huì)受
到male birds的打擾;
3. The eggs cannot be hatched.在最近的一次嘗試當(dāng)中 ,第1次生烏鴉寶寶的female bird
下蛋之后照顧很久,蛋也沒有孵化。.
Listening
1. captive-raised crows can be trained to avoid predators.有兩種方法可以訓(xùn)練它們:第- -,
可以播放hawks捕獵的recordings或是wamning cries of crows;第二,可以給它們看真實(shí)的
hawks是怎么捕獵的;
2. Researchers 已經(jīng)找到筑巢時(shí)male birds disturb female birds的原因了: crows是social
birds,也就意味著它們習(xí)慣于互相interact,但是captive raised birds are in isolation,所以
female birds在野外筑巢的時(shí)候,male birds 會(huì)去打擾。如果把female 和male birds養(yǎng)在一
起,就不會(huì)出現(xiàn)這種情況了,
3.沒有辦法hatch the eggs的主要原因并不是這些captive raised crows的問題,而是這些
eggs本身就是infertile的。這是因?yàn)閒emale birds是在unsuccessul mating之后下的蛋。在
最近的嘗試當(dāng)中,放生的crows都是frstime parents, 對(duì)于frst-time parents 來(lái)說,itis
common to fail. 如果它們多嘗試幾次,-定可以成功交配并且產(chǎn)下fertile eggs that can be
hatched.
Task2
Job sharing means that 2 partime workers share the work, hours and income. Job sharing
helps workers with their ownresponsibilities, such as those who want to study or those who
need flexible working time, to do their own things. Do you agree that job sharing is good for
workers? Why?
由于篇幅的問題,以上只是一部分,更多內(nèi)容請(qǐng)繼續(xù)關(guān)注我們中國(guó)教育在線外語(yǔ)頻道。
